Disclosed is a docking station for an electronic device having a housing, a top surface of the housing for receiving the electronic device, a plurality of positioning members of the top surface for positioning the electronic device with respect to the top surface, a first sensor for detecting the presence of the electronic device, a first connector block, a first connector of the first connector block, a first arm of the first connector block, a motor connected to the first arm via one or more gears, and a security hole for attaching a lock.

BACKGROUND OF THE INVENTION

Field of the Invention

The embodiments of the invention relate a docking station for an electronic device, and more particularly, to a software controlled, horizontally oriented docking station for a laptop computer. Although embodiments of the invention are suitable for a wide scope of applications, it is particularly suitable for use with laptop computers that have ports on two opposing sides and for protecting an electronic device from unauthorized removal from a docking station.

Discussion of the Related Art

The related art docking stations include docking stations for laptop computers. Docking stations of the related art are generally of the form disclosed in U.S. Pat. No. 6,309,230 to Helot, particularly FIG. 1 and FIG. 2. The related art docking stations generally interface with an electronic device such as a laptop computer. The electrical connection between electronic device and docking station is generally achieved through a single, multi-pin docking port. The related art docking station generally provides a multitude of additional interface ports connected to the docking port.

Docking stations of the related art also include multi-plug to multi-port docking stations such as disclosed in U.S. Pat. Pub. 2013/0148289 of Kitae Kwon (“Kwon”), particularly in FIG. 2 (multi-plug), and FIG. 6 (multi-port). See also U.S. Pat. Pub. 2012/0127651 of Kitae Kwon, et. al. Kwon discloses, generally, a plurality of plugs on a sliding arm that can be activated by a lever. When the lever is activated, the arms squeeze together and engage the plurality of plugs with the corresponding ports of an electronic device. Kwon also discloses using a Kensington-style lock to bind the sliding arm to the chassis and prevent movement sliding arm.

The related art docking stations also include opposing connector blocks. To connect a computer to the related art docking stations, a user positions the electronic device within the docking station, and activates a lever to cause the opposing connector blocks to press into the electronic device thereby making an electrical connection between the docking station and the electronic device. In the related art, the opposing connector blocks can be connected to the lever through a hinge or a cam. Both the hinge and cam are described in U.S. Pat. Pub. 2013/0148289 of Kitae Kwon, particularly in FIG. 1A, FIG. 1B (cam), and FIG. 4 (hinge). See also U.S. Pat. Pub. 2012/0127651 of Kitae Kwon, et. al.

There are some disadvantages of the related art systems. For example, the related art docking stations rely on a lever to so that a user can manually actuate the connector blocks. The lever is generally offset from the axis of the connector blocks the lever can be accessible by a user. An offset lever creates a non-linear force on the connector block and can cause misalignment of the connector block and prevent the connector block from interfacing with the docked device as designed. The lever also has the disadvantage that it must be moved to effectuate docking and undocking. The lever can be challenging to manipulate on a crowded desk or by a person having limited dexterity.

The related art docking stations are also generally passive—the dock does not have awareness of whether an electronic device is present or if the connectors of the connector blocks are inserted into the docked device. A passive docking station cannot, for example, detect whether the electronic device is properly positioned within the dock.

The related art docking stations also have a predetermined range of motion for the connector blocks. This range of motion is determined by the length of the lever arms and hinges or the size of the cam. Mechanical devices, however, tend to wear with extended use. As the related art begins to wear, the range of motion for the connector blocks can become sloppy or loose. Because docking requires high tolerances, a loose connector block could cause misalignment or incomplete insertion.

The related art of Helot, requires that the electronic device includes a docking connector. Thus the docking station of Helot cannot be used with electronic devices that do not include a docking connector. Helot is also limited in that Helot does not provide a mechanism to secure either the electronic device or the docking station. While Kwon teaches using multiple plugs instead of a docking connector and using a Kensington-style lock to secure the electronic device and docking station, Kwon does not allow removal of the electronic device without also manually removing the Kensington-style lock.

Laptop computers generally include an integrated audio device to allow audio output to integrated speakers or a headphone jack. However, most laptop computers include a hardware switch in a headphone jack that automatically disables the internal speakers of a laptop computer when a plug is inserted into the headphones jack. In most commercially available laptop computers the hardware switch in the headphones jack cannot be overridden by software such that if a plug is inserted in the headphones jack, playback through the internal speakers of the laptop computer is impossible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1is perspective view of a docking station for an electronic device. As shown inFIG. 1, the docking station has a tray100, a plurality of connectors110, a plurality of ports120, a plurality of pins130, and a security hole140. The tray100is formed to compliment the size and shape of the electronic device. The tray can hold the electronic device in position to interface with the plurality of connectors110. The plurality of connectors110can be positioned to match the location of corresponding ports of an electronic device.

The plurality of connectors110can be electronically connected to the plurality of ports120. The electronic connections can be pass-through meaning that each of the plurality of connectors110corresponds to one of the plurality of ports120and that the electrical signals between the connectors and ports are not altered by the docking station. The electronic connections can be active meaning that one or more of the plurality of connectors110can be electrically connected to circuitry and subsequently connected to one or more of the plurality of ports120. For example, one of the plurality of connectors110can be a USB connector electronically connected to a USB hub which is in turn electronically connected to more than one of the plurality of ports120.

The plurality of pins130can be the pins described in U.S. Pat. No. 8,512,080 to Vroom et. al, the entirety of which is hereby incorporated by reference. The security hole140can be sized to accommodate a Kensington style lock.

FIG. 2is a perspective view of connector block actuator of a docking station for an electronic device. As shown inFIG. 2the connector block actuator includes connector blocks200and230and gear box300. The connector block200is has a block-side arm portion210, a follower arm portion220, and an alignment arm205. The connector block230is has a block-side arm portion240, a follower arm portion250, and an alignment arm235. The gearbox300includes a motor310. The docking station includes sensor400for detecting when an electronic device is properly inserted into the docking station. The docking station can have a symmetrical sensor (not shown) on the opposite side near connector block200. The docking station can include a sensor420for detecting when a lock is inserted in the security hole140ofFIG. 1.

FIG. 3is a perspective view of connector block actuator of a docking station for an electronic device. As shown inFIG. 3the connector block actuator includes connector blocks200and230. The connector block200is has a block-side arm portion210, a follower arm portion220, and an alignment arm205. The connector block230is has a block-side arm portion240, a follower arm portion250, and an alignment arm235. The connector block actuator includes a motor310. The docking station includes sensor400for detecting when an electronic device is properly inserted into the docking station. The docking station can have a symmetrical sensor (not shown) on the opposite side near connector block200. The docking station can include a sensor420for detecting when a lock is inserted in the security hole140ofFIG. 1.

In operation, the motor310can turn the gears (not labeled) and cause the follow arm portions220and250to slide or traverse inwards and outwards. The follow arm portions220and250are connected to the block-side arm portions210and240(respectively) which are in turn connected to the connector blocks200and230(respectively). When an electronic device (not shown) is positioned in the docking station, the motor310can be activated to cause the connector blocks200and230to slide inwards thereby causing the plurality of connectors (not labeled) to be pressed into the electronic device. The motor310can be operated in a reverse direction causing the connector blocks200and230to slide outwards thereby causing the plurality of connectors (not labeled) to be removed from the electronic device.

When the connector blocks200and230are in an inward, “closed”, or “docked” position, the electronic device is securely retained in the docking station to prevent theft of the electronic device. The docking station can be locked to a stationary object by inserting a Kensington-style lock into the security hole140ofFIG. 1. In this way, an electronic device that is docked in the docking station is secured to the docking station, and the docking station is locked to the stationary object thereby preventing theft of either the docking station or the docked electronic device. The sensor420can detect the presence of a lock in the security hole140ofFIG. 1and optionally disable opening of the connector blocks200and230. The electronic device can interface with the docking station to determine the status of the sensor420and enable/disable docking through software. If the lock is removed from the security hole140, the docking station can allow normal docking/undocking without software.

The sensor420can also act as a reset switch. For example, when the sensor420is activated five times in rapid succession, the docking station can interpret that signal as a reset signal and cause the connector blocks200and230to move outwards into an “open” or “undocked” position. The presence of a lock in the security hole140can block the sensor420thereby preventing unauthorized resetting of the docking station and removal of the electronic device.

FIG. 4is a top view of connector block actuator of a docking station for an electronic device. As shown inFIG. 4the connector block actuator includes connector blocks200and230. The connector block200is has a block-side arm portion210, a follower arm portion220, and an alignment arm205. The connector block230is has a block-side arm portion240, a follower arm portion250, and an alignment arm235. The connector block actuator includes a motor310. The docking station includes sensor400for detecting when an electronic device is properly inserted into the docking station. The docking station can have a symmetrical sensor410on the opposite side near connector block200. The docking station can include a sensor420for detecting when a lock is inserted in the security hole140ofFIG. 1.

The docking station can include a sensor430for detecting the position of the connector block200or230. The sensor430can detect the position of a tab221or other movable feature and thereby infer the position of the connector block200or230. In the exemplary embodiment ofFIG. 4, a closed position can be indicated when the tab221is on the left edge of the sensor430. In the exemplary embodiment ofFIG. 4, an open position can be indicated when the tab221is on the right edge of the sensor430.

FIG. 5is a detailed top view of connector block actuator of a docking station for an electronic device. As shown inFIG. 5the connector block actuator includes a block-side arm portion210, a follower arm portion220, a block-side arm portion240, and a follower arm portion250. The docking station can include a sensor420for detecting when a lock is inserted in the security hole140ofFIG. 1. The follower arm portion220includes a rack-gear portion223. The follower arm portion250includes a rack-gear portion251.

The connector block actuator can include a motor310, a worm-gear320, a clutch-gear330, a pinion-gear340, and an emergency override gear350. InFIG. 5, the pinion-gear340has been moved and shown in perspective for clarity. The clutch-gear330has a slipping feature so that if the connector blocks or other moving parts become jammed or their movement is otherwise impeded that the motor310will not burn out or destroy the other gears.

The clutch-gear330also works in conjunction with the emergency override gear350. In the event of a power failure and an electronic device is in the docking station with the connector blocks in the closed position, the emergency override gear350can be manually manipulated with an allen key or like tool. Those of skill in the art will appreciate it is difficult to drive a worm-gear in reverse. The clutch-gear330allows the other gears to turn in response to a manual rotation of the emergency override gear350so that the connector blocks and arms can be positioned in the open position. The clutch-gear330in this instance slips so that the other gears may turn.

When rotated, the pinion-gear340causes the rack-gears223and251to move laterally and, consequently, move the connector blocks inwards or outwards.

FIG. 6is a perspective view of a pinion-gear. The pinion-gear340includes a smaller portion341and a larger portion342. The smaller portion341drives the rack-gears223and251ofFIG. 5. The larger portion342is driven by the motor via the other gears in the gearbox. A rotation of the larger portion342causes the smaller portion341to rotate and move the rack-gears.

FIG. 7Ais a perspective view of a clutch-gear andFIG. 7Bis a perspective view of a clutch-gear with portions removed for clarity. As shown inFIG. 7AandFIG. 7B, the clutch-gear330includes a first gear331, a second gear332, and a spring333. The spring333exerts a force on the second gear332and pushes the second gear332into the first gear331. The first and second gears331and332are thus held together by friction. If a force on one gear exceeds the friction force holding the two gears together, the clutch-gear330will “slip” and the first and second gears will be free to move independently. The opposing faces (not shown) of the first and second gears can have mating surface features such as ribs, bars, or ridges to increase friction between the gears and prevent unintended slipping.

FIG. 8is a perspective view of a connector block and arm. As shown inFIG. 8the connector block and arm includes a connector block200, a block-side arm portion210, an alignment arm205, and a follower portion220. The follower portion220includes a positioning indicator tab221for interfacing with the positioning sensor430. The block-side arm portion210is connected to the follower portion220with a linear clutch assembly215. The block-side arm portion210includes two rails212and two slider blocks211. The slider blocks211can be fixed to the block-side arm portion210. The rails212can slide freely within the slider blocks211. The block-side arm portion210can include cutouts213to allow the passage of a screw or tool for securing the rails212to retention slots on the underside of the top cover (600ofFIG. 18).

The block-side arm portion210includes a sensor part440and the follower portion220includes a sensor part445. The sensor part445can be a resistive pad that detects a change in resistance if the sensor part440moves. Together the sensor parts440and445can detect a movement between the block-side arm portion210and the follower portion220. In normal operation the block-side arm portion210should be rigidly secured to the follower portion220. In the event of a jam or misalignment of a component of the docking station, the linear clutch assembly215can slip allowing the follower portion220to move independently of the block-side arm portion210. Those of skill in the art will appreciate that other sensor designs can detect movement between the block-side arm portion210and the follower portion220.

FIG. 9is a perspective view of a connector block and arm. As shown inFIG. 9the connector block and arm includes a connector block230, a block-side arm portion240, an alignment arm235, and a follower portion250. The block-side arm portion240is connected to the follower portion250with a linear clutch assembly215. The block-side arm portion240includes two rails212and two slider blocks211. The slider blocks211can be fixed to the block-side arm portion240. The rails212can slide freely within the slider blocks211. The block-side arm portion240can include cutouts213to allow the passage of a screw or tool for securing the rails212to the underside of the top cover (FIG. 18). The block-side arm portion240can include a sensor part (not shown for clarity) similar to the sensor part440ofFIG. 8. The follower portion250can include a sensor part445.

FIG. 10is a top view of a docking station for an electronic device. As shown inFIG. 10, the docking station has a tray100, indexing points150,151,152, and153, vent slots160and161, vent notch170, sensor holes180and181, and recessed portions190. The tray is shaped to receive an electronic device such as an Apple MacBook Pro. The tray has indexing points150,151,152, and153to precisely position the electronic device within the tray. Indexing point150has a rounded portion positioned to indexing a rear surface and a first side surface of the electronic device. Indexing point151has a rounded portion positioned to indexing a rear surface and a second side surface of the electronic device. Indexing points152and153are protrusion from the tray100for indexing a front surface of the electronic device.

Vent slots160are positioned on the left and right sides of the tray100to allow airflow to the electronic device. Vent notch170extends along the back side of the tray100between indexing points150and151. Vent notch170allows airflow to the electronic device.

Sensor holes180and181can correspond to the position of sensors400and410ofFIG. 4. If the sensors400and410are mechanical button-style sensors, the sensors can protrude through the sensor holes180and181. The sensors400and410can be depressed when an electronic device is inserted into the tray100to indicate to the docking station that an electronic device has been inserted. Recessed portions190are sized to be larger than a foot of the electronic device. The feet of an electronic device are frequently contacted through normal use and can become worn causing the feet to be poor indexing points. The recessed portions190allow the feet of an electronic device to free float in the recessed portions190. The main surface of the tray can serve as an indexing point for the bottom of the electronic device.

FIGS. 11A-11Dare a detailed perspective views of a top surface of the docking station for an electronic device. As shown inFIGS. 11A-11Dthe indexing points150and151can be rounded to match the contour of the electronic device. The indexing points150and151can contact a side surface and a rear surface of the electronic device. The indexing points150and151can contact a bottom surface of the electronic device. The indexing points150and151can be shorter than a thickness of the electronic device. In preferred embodiments of the invention the indexing points150and151are shorter than a base portion of the electronic device so that a screen of the electronic device can open freely without interference from the indexing points150and151.

The vent notch170can be bounded on a left and right side by the indexing points150and151. The vent notch170can be formed in the tray100, and in preferred embodiments is generally referred to as the area bounded by the tray100and the dotted line.

FIG. 12is a detailed perspective view of an arm of a connector block actuator with a linear clutch removed. As shown inFIG. 12, the connector block actuator includes a block-side arm portion210and a follower portion220. The block-side arm portion210has a cutout214. The follower portion220has a slot222. The block-side arm portion210can have a sensor part440and the follower portion220can have a sensor part445. The docking station can include a sensor430for detecting the position of the connector block (not shown). The sensor430can detect the position of a tab221or other movable feature and thereby infer the position of the connector block (not shown).

The block-side arm portion210can be connected to the follower portion220by a linear clutch (SeeFIG. 13A). In the event of an obstruction or jam, the block-side arm portion210can slide in the direction of the slot222of the follower portion220.

FIG. 13AandFIG. 13Bare a perspective views of a connector assembly for a linear clutch. The linear clutch ofFIG. 13Bhas portions removed for clarity. As shown inFIG. 13AandFIG. 13B, a linear clutch has a bottom alignment member500, a bottom slider member510, a top slider member520, a bottom washer530, a spring540, a top washer550, and a bolt560. The bolt560has a slot portion570. The bolt560can thread into the bottom alignment member500to tighten the assembly.

Referring toFIGS. 12, 13A, and 13B, the top surface of bottom slider member510can contact a bottom surface of the follower portion220. The follower portion220can have a channel shape and the bottom alignment member500can be sized to fit in the channel of the follower portion220. The bottom surface of the top slider member520can contact a top surface of the follower portion220. The top and bottom slider members510and520can be formed from plastic or metal. The bottom washer530can exert an even force on the top slider member520. The bottom washer member530can be sized to fit in the hole214of the block-side arm portion210.

The linear clutch can have a spring540. The spring540can be compressed to apply a constant force to the components of the linear clutch. The top washer550can be positioned on top of the spring540and below the head of the bolt560. When the bolt560is tightened, the head of the bolt560applies a force to the top washer550which in turn compresses the spring540. A slot portion570of the bolt560can pass through the slot222ofFIG. 12.

The linear clutch can be tightened so that the block-side arm portion210and the follower portion220are held fast during normal operation. In the event that the actuator mechanism becomes jammed or blocked, the clutch can “slip” to allow the block-side arm portion210to slide in the direction of the slot222of the follower portion220. This slipping feature can prevent damage to the docking mechanism or electronic device in the event of an error.

A slip of the linear clutch can be detected by the sensor parts440and445ofFIG. 12. If a slip is detected, the docking station can be programmed to cause the port-blocks to open to their maximum positions thereby resetting the linear clutch to where the slot portion570of the bolt560is in the left most side of the slot222ofFIG. 12.

FIG. 14is a bottom view of connector block actuator of a docking station for an electronic device,FIG. 15is a detail bottom view of the connector block actuator ofFIG. 14, andFIG. 16is a detail perspective view of the bottom of the connector block actuator ofFIG. 14. As shown inFIG. 14,FIG. 15, andFIG. 16, a connector block actuator can include connector blocks200and230. The connector block200is has a block-side arm portion210, a follower arm portion220, and an alignment arm205. The connector block230is has a block-side arm portion240, a follower arm portion250, and an alignment arm235. The connector block actuator includes a motor310, clutch gear330, and emergency override gear350. The docking station includes sensor400for detecting when an electronic device is properly inserted into the docking station. The docking station can have a symmetrical sensor410on the opposite side near connector block200. The docking station can include a sensor420for detecting when a lock is inserted in the security hole140ofFIG. 1. The docking station can include a button450for causing the dock to open or close the port blocks200and230. The button450can be a capacitive touch button. The follower portion220can have a slot222. The block-side arm portion210can be connected to the follower portion220by a linear clutch215.

FIG. 17is a perspective view of an emergency override gear. As shown inFIG. 17, the emergency override gear350includes a lock-collar351, locking members352, and a manual interface353. The lock-collar351can surround the locking members352. The locking members352can interface with teeth of the lock-collar351. The manual interface353can be a keyed interface for accepting a tool such as an allen wrench or screw driver. The effect of the lock-collar351and locking members352can be to only allow the manual interface353to be turned in a single direction. The single direction can be the direction associated with opening the port blocks of the docking station.

FIG. 18is a bottom view of a top surface of a docking station for an electronic device. As shown inFIG. 18, the bottom-side of the top surface of the docking station can include retention slots600for the rails212ofFIG. 8. A screw can secure the rails212ofFIG. 8in the retention slots600. The bottom-side of the top surface can include sensor holes180and181and alignment slots610. The alignment slots610can be shaped and positioned to accommodate the alignment arms205and235ofFIG. 2. The sensor holes180and181can be positioned to allow the sensors400and410ofFIG. 4to detect whether an electronic device is in position for docking.

FIG. 19is detail view of a slide mechanism for an arm of a connector block actuator. InFIG. 19, the block-side arm portion (210ofFIG. 4) has been removed for clarity. As shown inFIG. 19, the slide mechanism includes rails212and slider blocks211. The rails212can be sized to fit into retention slot600. The rails can be held in the retention slot600by inserting an appropriately sized screw or other fastener into hole605. The slider blocks211can be attached to the block-side arm portion (210ofFIG. 4) and can slide freely on the rails allowing the port block (200ofFIG. 4) to slide between an open and closed position.

This configuration is advantageous as the main connection points for the moving parts are located on the underside of the top tray. The indexing points for positioning the electronic device are on the top surface of the top tray. In this way, the components of the docking station that require the most precision can be anchored to common structural element such as the top tray. Such a configuration can limit tolerance stacking as the anchor points for moving parts can be located on the same structural element as the indexing members.

FIG. 20is a block diagram of hardware and software systems according to an exemplary embodiment of the invention. As shown inFIG. 20, the system includes docking station components1000and electronic device components1030. The docking station components include the docking station hardware components1010and the docking station firmware components1020. The electronic device components1030include the electronic device hardware components1040, electronic device operating system1050, and electronic device docking software components1060.

With reference to the docking station components1000, the docking station hardware components1010can include the physical structures that enable the docking station such as electronics, circuit boards, gears, motors, etc. More specifically, the docking station hardware components1010can include the structures shown inFIG. 1-FIG. 19. The docking station hardware components1010can include a docking station controller that includes docking station firmware1020. The docking station controller can have a USB connection to one of the plurality of plugs110shown inFIG. 1.

The operation of the docking station controller can be governed by the docking station firmware1020. The docking station controller and docking station firmware1020can receive inputs from sensors400,410ofFIG. 4, sensors420, and430ofFIG. 4, and sensor440ofFIG. 12. The docking station controller and docking station firmware1020can control the motor310ofFIG. 4. The docking station controller and docking station firmware1020can include a communications function for communicating with the electronic device1030present in the docking station. The communications can be, for example, via a USB connection.

The docking station firmware1020can receive a signal from sensors400,410ofFIG. 4to determine whether an electronic device is properly positioned within the tray110. The docking station firmware1020can receive a signal from sensor430to determine whether the connector block is in the open or closed position. Sensor420can be a reset switch that, when pressed, sends a signal to the docking station firmware1020. The docking station firmware1020can interpret the signal from the sensor420and reset the docking station to a factory defaults. The docking station firmware1020can interpret the signal from the sensor420and cause the port blocks to move to an open position.

The docking station firmware1020can have a firmware upgrade feature such that the firmware can be updated via USB. The docking station firmware1020can receive a signal from sensor440to indicate a slippage in the mechanical components. In the event of a slippage, the docking station firmware can mechanically reset the dock by running the motor in reverse thus opening the port blocks to the maximum position.

The docking station firmware1020can control the motor310to open and close the port blocks. The docking station firmware1020can monitor the current draw of the motor as an indicator of an error condition. In the event of a jam or misalignment, the motor will work harder, turn slower, and accordingly draw additional current. The current draw of the motor310can also indicate that the port blocks are fully inserted into the docking station. For example, as motor310draws the port blocks into the electronic device, the motor310will turn slower, and therefore draw more current, when the port blocks are fully inserted. One of skill in the art will appreciate that the docking station firmware could similarly monitor a voltage drop instead of the current draw to achieve the same sensor capabilities.

The electronic device hardware components1040can include standard computer components such as keyboard, monitor, mouse, motherboard, network card, WiFi/Bluetooth, and hard drive. The electronic device operating system1050can be any operating system such as Apple's OSX, Microsoft Windows, or Linux variant. The electronic device docking software components1060can be used to interface with the docking station1000and more particularly, the docking station firmware.

The electronic device docking software components1060can include a messaging module that can send a message to the docking station firmware1020to open or close the port blocks (i.e. dock or undock). The electronic device docking software components1060can receive a message from the docking station that a user has pressed an “undock” button and cause the electronic device to dismount attached storage devices. The electronic device docking software components1060can send a message to the docking station firmware1020to set the docking station to a locked or unlocked state. When in a locked state, authorization can be required to open or undock the electronic device or to set the docking station to an unlocked state.

The electronic device docking software components1060can be used to select an audio input/output device with audio input/output selection modules. In preferred embodiments, a docking station includes a USB audio device and a PCIe audio device. The USB audio device can have an input/output of standard 3.5 mm or ⅛″ headphone jack. The PCIe audio device can be an audio device connected to a display device such as a display connected via thunderbolt. In certain embodiments, the docking station can include a HDMI audio device, such as the audio device and speakers of an external monitor connected to the docking station via HDMI. In this instance the electronic device docking software components1060can selectively enable any of the connected audio devices. The electronic device docking software components1060can further enable/disable or mute/unmute an internal audio device of the electronic device.

The electronic device docking software components1060can include a dismount module to automatically dismount all externally attached storage devices. The dismount module can ensure that all write buffers have been written to disk and that all attached storage devices have been cleanly dismounted before undocking.

The electronic device docking software components1060can further include a profile manager. The profile manager can set the electronic device to a particular state given a set of conditions. For example, in the case where the electronic device is docked with an external monitor, the profile manager can position preselected windows onto the external monitor. Similarly, when undocked, the profile manager can reposition the windows onto a screen of the electronic device. The profile manager can further enable a preselected audio device based upon the device being in a docked/undocked state.

The profile manager can determine a profile based upon a set of conditions. As an example of a condition, the profile manager can detect the presence of the docking station to know that the electronic device is in a “docked” state. Similarly, the profile manager can detect the presence of a particular Wifi access point, attached peripheral, or GPS coordinates to determine that the electronic device is at home, office, or other location associated with a profile. The conditions that define a profile can be set by a user. The device settings for a given profile can also be set by a user. For example, profile manager can detect that the electronic device is in a docked state and near an access point “X” associated with an office and, in response, position an email window on an external monitor and select an audio device associated with headphones. When the electronic device is undocked, the profile manager can still detect the presence of access point X and reposition the email window to the monitor of the electronic device and selects/enables an internal audio device of the electronic device. When the electronic device is subsequently in a docked state and detects an attached peripheral associated with a home location, the docking station can, for example, position an audio player window on an external monitor and select an audio device associated with a home stereo system.

FIG. 21is a block diagram of the electronic hardware components of a docking station according to an exemplary embodiment of the invention. As shown inFIG. 21, the docking station1100includes a USB hub1110, USB audio device1120, a PCI/MiniDisplay Port controller (ThunderBolt)1130, a USB SD card reader1140, a USB docking station controller1150, a charge controller1160, a USB Ethernet device1170, a ThunderBolt USB Hub1180, and a PCIe/MiniDisplay Port Audio Device1190.

The USB Hub1110can be electrically connected to a USB plug on the docking station. When in a closed or docked position, the USB plug can interface with a corresponding port of the electronic device. The USB hub1110can allow many USB devices to be connected to a single USB port of the electronic device. The USB audio device1120, USB SD card reader1140, and USB Ethernet device1170can be connected to the USB hub1110. The USB docking station controller1150can be connected to the USB hub1110or be electrically connected to a USB plug on the docking station that interfaces with a corresponding port of the electronic device.

The charge controller1160can receive electrical power from an external power source and provide power to the electronic device via the plurality of pins130shown inFIG. 1. The charge controller1160can communicate with components of the electronic device to determine the charge level, temperature, and charge rate of a battery of the electronic device. The charge controller1160can optionally convert AC power to DC power or DC power to DC power.

The PCI/MiniDisplay Port controller (ThunderBolt)1130can be connected to the electronic device through the docking station via a ThunderBolt plug. The PCI/MiniDisplay Port controller1130can have a number of output ports that are disposed on a rear portion of the docking station and can be used to attach external monitors and other ThunderBolt devices. The PCIe/MiniDisplay Port Audio Device1190can be connected to the PCI/MiniDisplay Port controller1130. The ThunderBolt USB Hub1180can be connected to the PCI/MiniDisplay Port controller1130to provide a plurality of USB ports. In certain embodiments, the USB Ethernet device1170can be connected to the PCI/MiniDisplay Port controller1130rather than connected via USB.

Those of skill in the art will appreciate that a variety of communications devices such as USB, Ethernet, Thunderbolt, Firewire, etc, can be integrated into the docking station and connected to the electronic device via an appropriate connector or communications protocol. Therefore, while particular communications technologies have been discussed herein, one of skill in the art will appreciate that other communications technologies can be substituted for those explicitly disclosed.

FIG. 22Ais a flow chart for docking an electronic device according to an exemplary embodiment of the invention. As shown inFIG. 22A, docking begins in step1200and can be initiated by a button press1205or other signal from a user. In decision step1210, the dock controller and firmware can detect the button press1205. If the button has not been pressed, the dock controller can wait or listen for a button press1205in the future. If the button has been pressed, the dock controller can check1215position sensors in the docking station to determine if an electronic device is present in the docking station and can detect if the electronic device is properly seated so that the plugs can enter the electronic device smoothly without binding. The position sensors can be the sensors shown inFIG. 4, reference numerals400and410.

The dock controller can read the input from the position sensors to determine1220if the electronic device is properly positioned. If the device is not properly positioned, the docking controller can indicate an error condition1225. In preferred embodiments of the invention, the docking station has a ring-shaped light surrounding a “dock” button. In the event of an error condition1225, the controller can change the color or display of the ring-shaped light to indicate the error condition. For example, the light can be blue or green and change to red or amber to indicate an error condition. The dock can revert to blue or green after five seconds. In the alternative, the dock can include a speaker or piezoelectric buzzer to emit a chirp or series of chirps in the event of an error condition. In the alternative, the dock can send an audio signal to an attached audio device to play an error sound over attached speakers. After the error condition1225is indicated, the dock can revert to the “waiting” state1205where the dock controller is listening for a button press or other indicator that docking is to commence.

If the electronic device is properly positioned, the docking controller can begin inserting1230the plugs into the electronic device. In preferred embodiments of the invention, the force to insert the plugs is provided by a motor. While the plugs are being inserted, the docking controller can detect an error condition1235. An error condition1235can be, for example, that the plugs have become jammed or are binding while being inserted into the electronic device by the motor.

The error condition1235can be detected by a sensor, such as the positioning sensors described in conjunction with step1215. The error condition1235can also be detected by a sensor, such as sensor440ofFIG. 5. InFIG. 5, the block-side arm portion210is connected to a follower arm portion220via a linear clutch as shown inFIG. 12,FIG. 13A, andFIG. 13B. If the insertion of the plugs is blocked, jammed, or the insertion force exceeds a mechanical limit, the linear clutch can slip allowing the two arm portions to move independently. The sensor440can detect the slippage between the two arm portions and indicate the error condition to the dock controller. The mechanical limit can be set by the selection of materials in the linear clutch. In exemplary embodiments of the invention, the mechanical limit is approximately five to ten pounds. The exact mechanical limit is not critical—it is sufficient that the mechanical limit exceed the insertion force required to insert the plugs. Similarly, it is desirable that the mechanical limit is not so high that damage to the docking station or electronic device occurs in the event of an error condition.

If an error is detected at step1240, the dock controller can reverse the motor and thus plug insertion1245. Optionally, the dock controller can mechanically reset the slip clutch by running the motor in reverse to the maximum extent. The dock controller can indicate an error condition1250and transition to a “waiting” state1205for detecting a press of the “dock” button.

If an error condition is not detected at1240, the docking controller can detect whether insertion of the plugs into the electronic device is complete1255. The detection of a complete status can be determined by a sensor, such as sensor430ofFIG. 2. Alternatively, the detection of a complete status can be detected by a spike in the current draw on the motor, or a voltage drop across the motor. If insertion is complete, the process can transition to an end state1280.

If there is no error condition1235, and insertion1255is not complete, the dock controller can detect a “cancel” signal1265. A cancel signal can be generated by a user of the docking station when, for example, when the user decides that they no longer want to initiate docking. In this instance, insertion of the plugs1230can be aborted by pressing a cancel button1265or similar indicator. The cancel button can be an independent button from the “dock” button. In preferred embodiments of the invention, the “dock” button and the “cancel” button are the same button. During plug insertion1230, the dock controller can interpret subsequent presses of the dock button as a “cancel” signal. If a cancel signal is not detected at1270, the process can cycle back to checking for error conditions1235. This cycle of checking for errors, completion, or a cancel signal continues. If the cancel button was pressed at step1270, the dock controller can reverse plug insertion1275by reversing the motor and the process can end at a step1280.

FIG. 22Bis a flow chart for docking an electronic device including exemplary additional steps toFIG. 22A. The flow chart ofFIG. 22Bshows optional, additional, “handshake” step that can occur after the plugs have been successfully inserted according toFIG. 22A. As shown inFIG. 22B, if the plugs have been successfully inserted1260into the electronic device, the process can transition to the optional handshake step1261. If the insertion1260was not successful, the process can transition to step1265ofFIG. 22A. In the handshake step1261, the docking station verifies that the computer being docking in the docking station is the computer that set the lock. The handshake1261can prevent an electronic device from becoming locked in the docking station where the owner of the electronic device is not authorized to remove the electronic device from the docking station.

In the handshake step1261, the electronic device can send an identifier to the docking station. The identifier can be any information sufficient to identify an electronic device to the docking station. The identifier can be, for example, the MAC address of an Ethernet device in the electronic device. The identifier can be, for example, a serial number of a motherboard or other hardware device in the electronic device. In the case of an enterprise with many docking stations, the identifier can be an enterprise identifier that is shared between all electronic devices. Upon receiving the identifier, the docking station can compare the identifier to a stored identifier or list of stored identifiers. If there is a match, the docking station will know that the electronic device is “known” to the docking station and, presumably, the user of the electronic devices has the necessary credentials to subsequently undock the electronic device.

The handshake1261can ensure that an unknown device, such as a laptop computer of a guest or visitor, is not accidentally docked to a docking station in the locked state. Without such a handshake1261, an electronic device could conceivably be docked to a “locked” docking station when the user or owner of the electronic device does not have credentials to unlock or undock the docking station. Similarly, if an electronic device does not have software installed to communicate with the docking station, it will not become locked in the docking station.

If at step1262, the handshake is unsuccessful (indicated an unknown device) or there is a timeout (indicating the electronic device is off or does not have appropriate software), the process can transition to step1275wherein the docking station controller reverses the plug insertion thus freeing the electronic device from the docking station.

FIG. 23is a flow chart of undocking according to an exemplary embodiment of the invention. The flow chart ofFIG. 23can be applicable when, for example, when a user presses an “undock” button on the docking station and the electronic device is in an “on” state. The “undock” button can be a separate and independent button from the “dock” button. In preferred embodiments of the invention, the “undock” button is the same as the “dock” button. When the dock is a “docked” state, the dock controller can interpret a signal from the “dock” button as signal to “undock”. As shown inFIG. 23, undocking can begin1300by detecting1305a signal from the “undock” button on the docking station. If no “undock” signal is detected at step1310, the docking station can continue to check1305for an “undock” signal. If an “undock” signal is detected1310, for example, via pressing the undock button on the docking station, the docking station can next detect1315whether the docking station is in a “locked” state.

The purpose of the “locked” state is to prevent the removal of the electronic device from the docking station. In use, when an electronic device is docked, plugs enter the electronic device from both sides and secure the electronic device to the docking station. The electronic device can only be removed when the plugs are removed, thus freeing the electronic device. Accordingly, the electronic device can be secured in the docking station by preventing removal of the plugs (preventing undocking) when the docking station is in a “locked” state.

In preferred embodiments of the invention, the plugs are electrical plugs that electrically interface with the electronic device. In other embodiments, the plugs can be “dummy” plugs formed from nylon or other sturdy yet non-electrically conductive material. In embodiments utilizing dummy plugs, the plugs on one side of the docking station can be electrically functional plugs and plugs on the opposite side can be dummy plugs. Embodiments utilizing dummy plugs can save the cost of electrical components while still achieving the benefit of the locking capability.

The docking station can be set to a “locked” state by a user of the electronic device. The docking station can be set to a locked state, for example, by pressing and holding the “dock” button for five seconds. The docking station can be set to a locked state by a remote administrator. The “locked” state can be represented by setting a bit or a flag in the dock controller. Docking and undocking can be achieved by the motor and gears shown inFIG. 5. The motor can be controlled exclusively by the dock controller. When the docking station is in a “locked” state, the dock controller can ignore or reject messages or requests to undock the electronic device thus securing the electronic device in the docking station. The docking station can be physically attached to a large stationary object with a Kensington-style lock thus preventing removal of the docking station and electronic device together.

An electronic device locked in the docking station can also be protected against unauthorized access to data when a thief has physical access to the electronic device. For example, a common attack is to boot a password-protected electronic device from an external storage device to gain access to data stored on the hard drive of the electronic device. If, however, the electronic device is locked in the docking station, the ports on the left and right sides of the electronic device can be physically covered by the docking station thereby preventing attachment of an external storage device. Similarly, a thief could not physically access and remove an internal hard drive of the electronic device because doing so would require disassembly of the electronic device—a challenging task when the electronic device is locked in the docking station.

Detecting lock state1315can include checking whether the bit or flag indicates a locked state. At step1320, if the docking station is not in a locked state, the undock process will transition to “request confirmation” step1325. At step1325, the dock controller can send a message to software running on the electronic device indicating that the “undock” button has been pressed. The software running on the electronic device can prompt a user of the electronic device to confirm1330that they desire to undock. If the user does not confirm, or a timeout condition occurs, the process can end at step1345. If the user confirms at step1330, the software running on the electronic device can cause attached storage devices to dismount in step1335and all caches and buffers be written to the attached disks. When the software running on the electronic device detects that the attached storages have been dismounted in step1335, the electronic device can send an “undock” message to the dock controller to remove the plugs1340from the electronic device. Upon receiving the “undock” message, the dock controller can activate the motor to remove the plugs from the electronic device. When the docking station detects that the plugs are completely removed, the process ends1345.

In the event that the docking station is locked at step1320, the dock controller can authorize removal of the electronic device in step1350. Authorization can be accomplished in many ways. For example, authorization can include sending a “request authorization” message from the dock controller to software running on the electronic device. Upon receiving the “request authorization” message, the electronic device can prompt the user to enter a password. In preferred embodiments of the invention, the password (or a password hash) is stored in memory on the docking station. Accordingly, authorization further includes sending a password entered by the user to the dock controller. The docking controller can subsequently compare the entered password to the stored password1355and, if the passwords match, set the docking station to an “unlocked” state1375.

Authorization can also be provided by a hardware key connected to the docking station or electronic device. In this instance, when the electronic device receives the “request authorization” message from the docking station, the electronic device can check for the presence of the hardware key and, if the key is present, send a message to the docking station indicating authorization was successful1355and setting the docking station to an “unlocked” state1375.

Authorization can also be provided by the presence of a cellular telephone. In common user scenarios, a user is likely to desire the electronic device to be secured against theft while the users is not present, but easy to remove while the user is present. The presence of a user can be determined, for example, if the user's cellular telephone can be detected by the electronic device. In this instance, when the electronic device receives the “request authorization” message from the docking station, the electronic device can check for a Bluetooth or WiFi signal emitted by the cellular telephone. If the cellular telephone is detected by the electronic device, the electronic device can send a message to the docking station indicating authorization was successful1355and setting the docking station to an “unlocked” state1375.

In the alternative, the electronic device can use an electronic identifier of the cellular telephone as a password. The electronic identifier can be, for example, the MAC address of a wireless card, a serial number, or other electronic identifier of the cellular telephone. The electronic identifier can be used as a password. In embodiments of the invention, the cellular telephone can include an app that provides a password to the electronic device which in turn provides the password to the docking station to authorize unlocking or removal of the electronic device.

If authorization was not successful, the process can transition to decision step1360where authorization is retried in step1350or aborted. For example, if authorization is unsuccessful, a user can indicate “cancel” to abort undocking. If authorization has failed multiple times, the docking controller and/or electronic device can automatically abort undocking.

FIG. 24is a flow chart of undocking according to an exemplary embodiment of the invention. The flow chart ofFIG. 24can be applicable when, for example, when a user presses an “undock” button on the docking station and the electronic device is in an “off” state.FIG. 24represents a special use-case because, if the electronic device is “off”, the electronic device cannot be used for authorization. As shown inFIG. 24, undocking an electronic device can begin1400by a user pressing an “undock” button1405on the docking station. In decision step1410, if the button is pressed or undocking is otherwise indicated, the process can transition to step1415where the dock controller determines whether the dock is in a “locked” state. At decision step1420, if the dock is in a “locked” state, the dock indicates an error condition1435and the process ends1430. Alternatively, if the docking station is not in a “locked” state, the dock controller can activate the motor to remove the plugs at step1425thus freeing the electronic device and ending the process1430.

FIG. 25is a flow chart of undocking according to an exemplary embodiment of the invention. The flow chart ofFIG. 25can be applicable when, for example, when a user initiates undocking from the electronic device. As shown inFIG. 25, undocking can start1500when an “undock” command is detected1505by software running on the electronic device. An undock command can be generated by many circumstances, for example, the software can have a button or menu item that generates an undock command or signal when selected. The software application can also recognize a hotkey or series of hot keys and, in response, generate the undock command, signal, or otherwise begin the undocking process1505. In decision step1510, when the undock command is detected, the process transitions to step1515where the software on the electronic device detects whether the dock is in a “locked” state. Detection of the dock state can be determined, for example, by sending a query to the dock controller. The dock controller in turn reads the “locked” bit or flag and returns the result to the software running on the electronic device. In the alternative, the “lock” state can be stored locally on the electronic device.

At decision step1520, if the device is “unlocked”, the electronic device can request confirmation1525from the user. Confirmation can be obtained, for example, by displaying a dialog to the user with two choices “confirm” or “cancel.” In decision step1530, if the user confirms, the software on the electronic device can dismount attached storage1535and when complete, send a message to the dock controller instructing the dock controller to remove1540the plugs from the electronic device thus completing the undocking1545.

If, at decision step1520, the docking station is in a locked state, the software running on the electronic device can authorize1550undocking according to the previously disclosed methods including password, hardware key, or cellular telephone detection. In decision step1555, if authorization is successful, the electronic device can send a message to the dock controller instructing the dock controller to set the dock to an unlocked state1575. The software on the electronic device can then dismount attached storage1535and when complete, send a message to the dock controller instructing the dock controller to remove1540the plugs from the electronic device thus completing the undocking1545. In decision step1555, if authorization is not successful, the process can transition to cancel undocking step1560.

In preferred embodiments of the invention the docking station is maintained in the “locked” state even when undocking. In these cases, after successful authorization, the step of unlocking the dock1575can be skipped and the undocking process can proceed to dismounting1535and removing plugs1540. This embodiment can be preferable in circumstances where a user desires the electronic device to be always locked when docked. There are also efficiencies to maintaining the dock in a locked state. For example, a user would not have to manually set the dock to a locked state.

When the dock is “open” and also “locked” an undesirable operating method is possible. For example, if a user inserts an electronic device that is not loaded with the appropriate software to communicate with the dock controller and the user presses the “dock” button, the device can become irretrievably locked in the docking station. There are multiple safety mechanisms to prevent such undesirable operational modes. For example, if the docking is initiated when the dock is already in a “locked” state, the dock controller can ignore the “lock” status and allow undocking. As a second safety mechanism, when docking is initiated and the dock is in a “locked” state, the docking controller can communicate with the electronic device when docking is complete. Successful communication can indicate that the electronic device is loaded with the appropriate software and thus unlocking and undocking is possible via software. If communication is unsuccessful, the dock can automatically “undock” or allow undocking notwithstanding the lock bit. As a third safety mechanism, the dock controller can detect a signal from the reset button420ofFIG. 5and set the dock to an unlocked state. As a fourth safety mechanism, an emergency override gear350ofFIG. 5can be turned with an allen wrench to manually open the docking station.

FIG. 26is a flow chart of undocking according to an exemplary embodiment of the invention. The flow chart ofFIG. 26can be applicable when, for example, an undocking signal is received from a remote computer. A remote undock signal could be generated, for example, by an administrator of a computer lab that desires to remove all docked and locked laptops at once, such as for maintenance. In such a circumstance, a single undock command can be sent by a remote computer to the docking stations and attached electronic devices to initiate undocking simultaneously.

As shown inFIG. 26, remote undocking beings1600by sending an undock message from a remote computer1605. The undock message can be received1610by software running on a docked electronic device. The undock message can include an instruction to initiate undocking and an authorization token, such as a password. The electronic device then authorizes1615the remote computer by analyzing the authorization token. In the example where the token is a password, the password can be compared against a password stored on the docking station or the electronic device. In decision step1620, if authorization is successful, the software on the electronic device can optionally warn1625the local user that undocking is about to begin, ask the user to save work, and confirm to proceed. The undocking process can be aborted if the local user does not confirm. In the alternative, undocking can occur automatically (or be aborted) after the expiration of a predetermined time period, such as thirty seconds. The time period and an action to be performed at the expiration of the time period can be provided in the undock message. If the user confirms undocking at decision step1630or if a timeout was specified and a default action was set to “undock”, then the process can proceed to a step1635where the lock state is detected. In decision step1640, if the device is locked, the dock can optionally be unlocked at1645. Next, external storage devices can be dismounted1650and the plugs of the docking station can be removed1655thereby completing the process1660.

It is noted that the “unlock” step is optional and that undocking can be achieved while the docking station is in a locked state if authorization is successful. In such a circumstance, the docking station would be in an open or undocked state and “locked.” Any subsequently docked electronic device would become locked in the docking station.

Just as a remote computer can initiate undocking, a remote computer can further initiate setting the docking stations to a locked state. For example, an authorized remote computer can send a “lock” message to a docked electronic device present on a network. The remote sending of a “lock” message could be desirable in the event of a building evacuation where a network administrator desires to secure electronic devices against theft during the chaos of a building evacuation. In embodiments of the invention, the docking software of the electronic device can receive a lock message from a remote administrator and in response, set the docking station to a locked state. When a docking station is remotely set to a locked state, the docking station can disable undocking for a predetermined period of time—even if a user is otherwise authorized to undock the electronic device.

In embodiments of the invention, the docking software can detect if the electronic device was removed from a docking station without providing valid credentials. Such a circumstance could indicate theft of the electronic device, such as by forcefully breaking the docking station or by manually rotating the gears to remove the plugs from the electronic device. In such a circumstance, the electronic device can perform a set of actions that can be predetermined by an administrator of the electronic device. For example, the docking station software can call a script or program generated by an administrator of the electronic device that automatically encrypts or deletes sensitive user data. The script can delete cached passwords and internet browsing history. The script can activate a geolocation device such as GPS or WiFi and transmit the location of the electronic device back to the administrator. The script can activate a camera on the electronic device and periodically take photographs and transmit the photographs back to an administrator of the electronic device.

FIG. 27is an exemplary call flow between a dock controller of a docking station and a docked electronic device. As shown inFIG. 27, an exemplary call flow between an electronic device1700and a dock controller of a docking station1710can begin with a lock message1715to lock the docking station. The lock message can be sent from the electronic device1700to the docking station1710. The lock message can include an instruction to set the docking station to a locked state. The lock message can optionally include an authorization token such a password that can later be used to unlock the docking station. After receiving the lock message1715, the docking station can respond with a confirmation message1720that confirms to the electronic device that the docking station is now in a locked state. The electronic device can optionally store the lock status of the docking station to avoid unnecessarily requesting lock status from the docking station.

In the exemplary call flow, a user presses an “undock” button on the docking station1710causing the docking station1710to send a “request authorization” message1725to the electronic device1700. When the request authorization message1725is received the docking station can perform one of the aforementioned authorization methods to determine whether undocking is authorized. If undocking is authorized, the electronic device1700can send an unlock message1730to the docking station1710. The unlock message1730can include an instruction to set the docking station1710to an unlocked state. The unlock message1730can include an authorization token such as a password. Upon receiving the unlock message1730, the docking station can compare a previously stored authorization token to the authorization token provided in the unlock message1730and, if the tokens match, set the docking station1710to an unlocked state.

When the docking station1710is set to an unlocked state, the docking station1710can send an unlock confirmation message1735to the electronic device. If, however, the docking station1710was not set to an unlocked state (i.e. authorization failed), the docking station can send an authorization failure message (not shown) to the electronic device1700. Upon receiving the unlock confirmation message1735, the electronic device1700can begin dismounting attached storage devices. When dismounting is complete, the electronic device1700can send a “remove plugs” or “undock” message1740to the docking station1710. Upon receiving the undock message1740, the docking station can activate a motor contained therein to drive the gears thus removing the plugs from the electronic device1700.

FIG. 28is an exemplary call flow between a dock controller of a docking station and a docked electronic device wherein the docking station remains in a “locked state” after undocking. As shown inFIG. 28, an exemplary call flow between an electronic device1800and a dock controller of a docking station1810can begin with a lock message1815to lock the docking station. The lock message1815can be sent from the electronic device1800to the docking station1810. The lock message1815can include an instruction to set the docking station to a locked state. The lock message can optionally include an authorization token such a password that can later be used to unlock the docking station1810. After receiving the lock message1815, the docking station1810can respond with a confirmation message1820that confirms to the electronic device1800that the docking station1810is now in a locked state.

In the exemplary call flow, a user presses an “undock” button on the docking station1810causing the docking station1810to send a “request authorization” message1825to the electronic device1800. When the request authorization message1825is received, the docking station can perform one of the aforementioned authorization methods to determine whether undocking is authorized. In the case of password authorization, the electronic device can prompt a user to enter a password. Upon entering the password, the electronic device1800can “check” the password by sending an “authorize” message1830to the docking station1810. The authorize message1830can include an authorization token, such as the password. At the docking station1810, if the password matches the stored password, the dock can respond with an authorization confirmation message1835that indicates to the electronic device1800that the authorization was successful (or not). If the authorization confirmation message1835indicates that authorization was successful, the electronic device can now dismount attached storage devices and, when complete, send a “remove plugs” or “undock” message1840to the docking station1810. In this exemplary call flow, because the device was not unlocked, the undock message1840can also include the authorization token password.

FIG. 29is a perspective view of a port misalignment detection mechanism according to an exemplary embodiment of the invention. As shown inFIG. 29, a port misalignment detection mechanism includes electrical contacts1905and1910and one or more plugs1915. The electrical contacts1905can be located on a tray portion of the docking station and be positioned such the electrical contacts1905touch a chassis of an electronic device inserted into the docking station. The electrical contacts1910can be located on one or more plugs1915.

The electrical contacts1910can be positioned such that when the plugs1915are inserted into the electronic device in a misaligned orientation, the electrical contacts1910contact the chassis of the electronic device. The electrical contacts1910can be positioned on the plugs1915such that when the electronic device is properly aligned in the docking station and the plugs1915are inserted into the electronic device, that the electrical contacts1910do not contact the chassis of the electronic device.

Together, electrical contacts1905and1910can detect a misalignment of the electronic device in the docking station when the chassis of the electronic device is formed from an electrically conductive material such as aluminum. For example, the electrical contacts1905and1910can be part of an electrical circuit (see simplified circuit diagram inset onFIG. 13.) If both electrical contacts1905and1910contact the conductive chassis of the electronic device, the circuit can be completed indicating that the plugs of the docking station may be misaligned with the corresponding ports of the electronic device.

In alternative embodiments, the electrical contacts1910can be omitted and instead the metal portion of the plug1915can be used as an electrical contact. If the electronic device is misaligned in the docking station, the one or more plugs1915can contact a chassis portion of the electronic device thus completing the circuit between the electrical contact1905and the metal housing of the plugs1915. If a misalignment is detected the dock controller can indicate an error condition and reverse the insertion of the plugs1915.
