Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application claims priority from U.S. Patent Application Ser. No. 61/531,316, filed Sep. 6, 2011, the content of which is incorporated herein by reference in its entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present description relates generally to docking stations for mobile electronic devices, and in particular to methods and systems for docking and providing power mobile electronic devices. 
     2. Description of the Related Art 
     Many types of conventional docking stations and mounts exist for mobile electronic devices. Often, the docking station requires that the mobile electronic device be carefully plugged in to a mating connector each time the mobile electronic device is docked. Lack of care during the docking process can lead to damage to the docking station or mobile electronic device. To prevent this damage, the docking station may be constructed with a cavity or well to receive the mobile electronic device. The cavity or well of the docking station may help prevent damage due to lack of care during docking but do not prevent long time wear and tear on the docking station and the mobile electronic device mating connectors. 
     Recently, both conductive and inductive mats have been developed such as the WildCharge conductive charging mat the PowerMat inductive charging mat. The conductive and inductive charging mats often require that the mobile electronic device be inserted in a sleeve. The WildCharge mat is much larger than the WildCharge sleeve and the mobile electronic device. The PowerMat uses a slight well to receive the mobile electronic device and to position the mobile electronic device properly while charging. Charging mats are intended to be used on a relatively flat and horizontal surface and the mobile electronic device is not easily used while charging. Existing inductive chargers have been developed for low power devices that require 1 amp or less of charging current. Mobile electronic devices such as the Apple iPad require up to 2.1 amp of charging current so existing charging mats can&#39;t be used to charge the iPad. Certain inductive charging stations require that the device being charged be at a fixed orientation. 
     Non-charging mounts for mobile electronic devices have also been developed that allow the mobile electronic device to be held and operated in multiple orientations. The mounts require a cable from an external charger be plugged in to the mobile electronic device to charge or maintain a charge during use. The use of a charging cable in this type of mount restricts the movement or position of the mobile electronic device and will create the possibility of wear or damage to the mobile electronic devices charging connector and charging cable. 
     Semi-permanent mounts with integrated charging have also been developed such as the iPort CM-IW2000 that allow mobile electronic devices such as the iPad to be wall mounted and remain fully charged. The CM-IW2000 holding the iPad remains fixed in one position or orientation that is determined at the time the mounting hole for the CM-IW2000 is cut in a wall. The CM-IW2000 utilizes magnets to firmly secure the iPad in the mount and was not designed to allow the iPad to be removed easily and used as a mobile device.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     Disclosed herein are methods and systems of powering and/or charging mobile device. Certain embodiments provide a mobile device docking station that enables power to be provided to a mobile device at multiple orientations. Certain embodiments of the docking station are configured to charge a mobile device battery. Certain embodiments of the docking station are configured to supply power to the mobile device inductively and/or conductively. 
     In view of the deficits of conventional docking systems, such as those discussed above, there is a need for an improved docking system for mobile electronic devices that does not require plugging charging cables or docking connectors every time the mobile electronic device is charged, allows ease of use of the mobile electronic device during charging, permits multiple orientations of the device and allows the mobile electronic device to remain mobile and easily docked and undocked without excessive care. 
     Embodiments of a docking system is disclosed. As described in greater detail below, in certain embodiments, the docking system may include a sleeve and base. The sleeve may be a form fitted sleeve for a mobile electronic device. The base may be configured to hold the sleeve at multiple planes and or multiple orientations within a single plane. The sleeve is supported on the base using mechanical design features and/or magnetic force. The docking system may include at least one indention and at least one corresponding protrusion for locating the desired position of the sleeve on the base when docking and to allow rotation of the sleeve to alterative operating positions on axis after the sleeve is docked. The sleeve may include a connector port interface to the mobile electronic device. The base may include a connector port interface to an external power source. The docking system may include a conductive and/or inductive charging function for the battery within the mobile electronic device. 
     Referring to the drawings  FIG. 1 , is a simplified block diagram of inductive charging electronics for a docking system. The use of an inductive charging circuit in a docking station provides improvement over docking stations that require that the mobile electronic device be plugged in to a connector or cable that provides charging. Inductive charging is an improved method of charging that does not require electrical conducting connectors between the base  10  and the sleeve  9 . 
     Referring more particularly to  FIG. 1 , AC power  1  may be used provide a source of power for a docking system. AC power  1  may range for example from 90 V AC to 240 V AC at 50 Hz to 60 Hz depending on where you are located in the world, other AC power voltages and frequencies may also be used. The external power supply  2  receives input AC power for example of 90 V AC to 240 V AC at 50 Hz to 60 Hz from AC power  1 . The external power supply can be a wall mounted unit that is plugged directly in to an AC power  1  outlet and may use country specific plug adapters to mate with the style of AC power  1  outlet. A power source such as an external power supply  2  provides input power for the driver board  3  of the docking system base  10 . A DC power input from a battery system in a vehicle such as an automobile could also be used in place of the AC power and external power supply to provide input to the driver board  3 . The driver board  3  is used to drive electrical current in to the driver coil  4  at a frequency range for example of 60 KHz to 130 KHz, other frequencies may be used. The driver board  3  may be implemented using a small programmable micro controller allowing use of various sensor inputs and allow various modes of operation. A sensor may be included on the driver board  3  or within the base  10  that senses when the sleeve  9  is docked on the base  10 . A magnetic sensor on the driver board  3  or base may be used to detect the magnetic field from a permanent magnet in the sleeve  9  as an indication that the sleeve  9  has been docked on the base  10 . A current sensor may be included on the driver board  3  and used to detect the change in driver board  3  current when the sleeve  9  is docked on the base  10 . The base  10  may use the detection of the sleeve  9  to change the operating mode of the driver board  3 . The driver board  3  may have several operating modes including a power saving low power sleep mode when the sleeve  9  is not docked on the base  10 . 
     The low power mode, for example, may draw less than 1 W of power from the AC power input when the sleeve  9  is not docked on the base  10 . The driver board  3  may also use a current sensor to determine when to change charging modes and also to monitor and control the charging of the mobile electronic device  7 . The mobile electronic device  7  may require much more current to recharge the mobile electronic device&#39;s batteries when the batteries are very low. The driver board  3  may sense the current need of the mobile electronic device  7  using a current sensor and vary the driver board  3  drive current as needed. 
     The driver board  3  may also include a temperature sensor. A temperature sensor may be used by the driver board  3  to change operating modes of the driver board  3  based on ambient temperatures. The driver board  3  may change operating modes to a low power mode if high ambient or driver board  3  temperature is detected. 
     The docking system may be designed to pass radiated emission and conducted emission FCC specifications. The driver board  3  may cause undesired excessive radiated and conducted emissions when driving current to a driver coil  4  during charging. To minimize or reduce radiated emissions and conducted emissions caused by driving current to a driver coil  4 , the frequency of the driver board  3  coil drivers may be varied within the optimum operating frequency range of the docking system reducing peak level of measured emissions. 
     The driver coil  4  may consist of multiple turns of wire. Multi-strand wire may be used for the driver coil  4 . The use of multi-strand wire for the driver coil  4  increases efficiency of the drive coil  4  and reduces heat generated by the drive coil  4 . The multi-strand wire used for the drive coil  4  may have individual strands of wire that are as thin as 40 A WG for example and may consist of 50 or more strands of wire. The drive coil  4  may further have multiple turns of wire forming the coil on the bobbin that held is by the ferrite pot core. The ferrite core helps focus the energy of the driver coil  4  to the receiver coil  5 . The use of a ferrite pot core with the drive coil  4  increases the power that may be transferred to the receiver coil  5  allowing the inductive charging circuit to achieve the higher current demands of devices such as an iPad for example that may need over 2 amps of charging current at 5 volts. 
     The receiver coil  5  may be located in the sleeve  9 . The receiver coil  5  may be implemented as a coil formed with etched copper using a printed circuit board. The use of a circuit board for the receiver coil  5  reduces the overall thickness of the receiver coil  5  and therefore reduces the space required for the receiver coil  5  within the sleeve  9 . The receiver coil  5  may use both outer surfaces of the receiver coil  5  printed circuit board when fabricated using double sided copper clad printed circuit board material. The receiver coil  5  may alternately be fabricated using multilayer printed circuit board material allowing the turns of the receiver coil  5  represented in etched copper be placed in series therefore increasing the turns of the receiver coil  5  and increasing the receiver coil  5  AC voltage level that is determined by the ratio of the receiver coil  5  windings to driver coil  4  windings or in parallel reducing the resistance of the receiver coil  5  therefore increasing the receiver coil  5  current carrying capability and reducing the receiver coil  5  heat caused by the current flow during charging the mobile electronic device  7  resulting in a voltage drop caused by resistance of the receiver coil  5 . A flat piece of ferrite material may be placed on the side of the receiver coil  5  printed circuit board that is most distant from the driver coil  4  when the sleeve  9  is docked on a base  10 . A flat ferrite piece on the back of the receiver coil  5  may be used to increase the efficiency of the transfer of power between the driver coil  4  and the receiver coil  5  over the space or gap between the two coils. The receiver coil  5  may also fabricated using copper wire wound to form a coil and backed with a flat piece of ferrite material. 
     The main board  6  may be located in a sleeve  9  receives the AC input from a receiver coil  5 . A capacitor may be used in parallel with the receiver coil  5  to for near to resonance operation of the receive circuit. At resonance the transfer function of energy to the receive coil may approach  1  and therefore increase the efficiency of the inductive charging circuit allowing the circuit to deliver the higher charging currents required by mobile electronic devices such as the iPad. The AC input from a receiver coil  5  may be rectified in to unregulated DC voltage by a full wave bridge on a main board  6 . The unregulated DC voltage from the bridge rectifier may be used as the input for a DC to DC switching power regulator circuit on the main board  6 . 
     The use of a switching power regulator on a main board  6  may improve the efficiency for example from 20% to nearly 90% of the conversion of unregulated DC voltage input to regulated voltage output over the use of conventional linear voltage regulators. The switching power regulator may be configured to output regulated +5VDC output or other voltage for charging a mobile electronic device  7 . The output of a main board&#39;s  6  regulated DC output is used as the input to a connector board  8 . The connector board  8  may be located in the sleeve  9  and may include a mating connector  27  for the charging port on the mobile electronic device  7 . The connector board  8  may also include a connector that is accessible from the outside of the sleeve  9  that allows an alternate method to charge the mobile electronic device  7  using a conventional charger. 
     The mobile electronic device  7  charging port may plug in to a mating connector on the connector board  8  when a mobile electronic device  7  inserted in to the sleeve  9 . The sleeve  9  may be intended to remain in place on the mobile electronic device  7  semi-permanently and does not need to be removed for normal use of the mobile electronic device  7 . The sleeve  9  may be form fitting and also may provide a level of increased protection for the mobile electronic device  7 . The mobile electronic device  7  installed in the sleeve  9  may be placed on the base  10  to charge the mobile electronic device  7 . Optionally, no additional plugging of cables or connectors are required to charge the mobile electronic device  7  when installed in the sleeve  9  and placed on the base  10  that is receiving power from an external power supply  2 . The driver coil  4  of the base  10  may need to be aligned properly with the receiver coil  5  in the sleeve  9  to properly transfer power and allow charging of the mobile electronic device  7 . 
     Smaller magnets  35  in the sleeve  9  may be used to attract to ferrous metal in the base  10 . A combination of magnetic force and mechanical design features of a base  10  and a sleeve  9  may be used to enable the sleeve  9  to be easily docked properly aligning the receiver coil  5  and the driver coil  4  on the base  10  without excessive care from the intended user. The mechanical design features of the base  10  and the sleeve  9  also allow the sleeve  9  to be rotated to any position within a single plane while a sleeve  9  is installed on the base  10 . The magnetic force may be used to hold the base  10  and sleeve  9  together with enough force to allow the mobile electronic device  7  to be used normally while docked. The magnetic force between the sleeve  9  and base  10  may be such that it is not strong enough to prevent the mobile electronic device  7  held in the sleeve  9  from easily being undocked by a user and used as a mobile device. 
     Referring to the drawing  FIG. 2 , is a front perspective view of a docking system with table top base. 
       FIG. 2  shows the docking system when the sleeve  9  and the mobile electronic device  7  is docked on the base  10 . The base  10  may be constructed to hold the sleeve  9  and the mobile electronic device at any angle that allows the mobile electronic device  7  to be easily used while docked on a base  10 . The base  10  may have weight added for stability of the docking system. The sleeve  9  holding the mobile electronic device  7  may be rotated to any position within a single plane while the sleeve  9  is docked on the base  10 . The base  10  may alternately be constructed as a free standing module with a mating surface for the sleeve  9  at any useful angle or with a mating surface for the sleeve  9  that allows the mating surface angle or plane to be adjustable.

     Referring to the drawing  FIG. 15 , is a simplified block diagram of conductive charging electronics for a docking system. The use of driver contacts and receiver contacts and a conductive charging circuit in a docking station provides improvement over docking stations that require that the mobile electronic device be plugged in to a connector or cable that provides charging. 
     Referring more particularly to  FIG. 15 , AC power  1  may be used provide a source of power for a docking system. AC power  1  may range from 90 V AC to 240 V AC at 50 Hz to 60 Hz depending on where you are located in the world and other AC power voltages and frequencies may be used. The external power supply  2  receives input AC power 90 V AC to 240 V AC at 50 Hz to 60 Hz from AC power  1 . The external power supply can be a wall mounted unit that is plugged directly in to an AC power  1  outlet and may use country specific plug adapters to mate with the style of AC power  1  outlet. A power source such as an external power supply  2  provides input power for the driver contacts  54  of the docking system base  45 . A DC power input from a battery system in a vehicle such as an automobile for example may also be used in place of the AC power  1  and external power supply  2  to provide input to the driver contacts. The driver contacts  54  are used to transfer power the sleeve  38  when the sleeve  38  is docked on the base  45 . The driver contacts  54  may be spring loaded insuring a good electrical contact with the receiver contacts  55  on the sleeve  38 .

The receive contacts  55  are used to receive the power transferred from the driver contacts  54 . 
     The regulator board  56  receives the power input from the receiver contacts  55 . The regulator board  56  may be located in a sleeve  38 . The power input from the receiver contacts  55  may be rectified in to DC voltage by a full wave bridge or half wave bridge on the regulator board  56 . Alternately, if a DC voltage source is used for the driver contact  54  power then a full wave bridge or half wave bridge is not needed to create DC voltage. The DC voltage from the full or half wave bridge rectifier or DC power input from the receiver contacts  55  may be used as the input for a DC to DC switching power regulator circuit on the regulator board  56 . The use of a switching power regulator on the regulator board  56  may improve the efficiency from 20% to nearly 90% of the conversion of unregulated DC voltage input to regulated voltage output over the use of conventional linear voltage regulators. The switching power regulator may be configured to output regulated +5VDC output or other voltage for charging a mobile electronic device  7 . The output of a regulator board&#39;s  56  regulated DC output is used as the input to a connector board  57 . 
     The connector board  57  may be located in the sleeve  38  and may include a mating connector for the charging port on the mobile electronic device  7 . The connector board  57  may also include a connector that is accessible from the outside of the sleeve  38  that allows an alternate method to charge the mobile electronic device  7  using a conventional charger. The mobile electronic device  7  charging port may plug in to a mating connector  27  on the connector board  57  when a mobile electronic device  7  inserted in to the sleeve  38 . The sleeve  38  may be intended to remain in place on the mobile electronic device  7  semi-permanently and does not need to be removed for normal use of the mobile electronic device  7 . The sleeve  38  may be form fitting and also may provide a level of increased protection for the mobile electronic device  7 . The mobile electronic device  7  installed in the sleeve  38  may be placed on the base  45  to charge the mobile electronic device  7 . Optionally, no additional plugging of cables or connectors are required to charge the mobile electronic device  7  when installed in the sleeve  38  and placed on the base  45  that is receiving power from an external power supply  2 . The driver contacts  54  of the base  45  may need to be aligned properly with the receiver contacts  55  in the sleeve  38  to properly transfer power and allow charging of the mobile electronic device  7 . 
     Smaller magnets  35  in the sleeve  38  may be used to attract to ferrous metal in the base  45 . A combination of magnetic force and mechanical design features of a base  45  and a sleeve  38  may be used to enable the sleeve  38  to be easily docked properly aligning the receiver contacts  55  and the driver contacts  54  on the base  45  without excessive care from the intended user. The mechanical design features of the base  45  and the sleeve  38  also allow the sleeve  38  to be rotated to any position on axis within a single plane while a sleeve  38  is installed on the base  45 . The magnetic force may be used to hold the base  45  and sleeve  38  together with enough force to allow the mobile electronic device  7  to be used normally while docked. The magnetic force between the sleeve  38  and base  45  may be such that it is not strong enough to prevent the mobile device  7  held in the sleeve  38  from easily being undocked by a user and used as a mobile electronic device  7 . 
     Referring to  FIG. 16 ,  FIG. 16  is a simplified flow chart of the operation of the docking system microcontroller firmware. 
     The microcontroller is initialized when the docking system has power applied from the external power supply. This is the POWER ON state of the docking system. The microcontroller next initializes the internal registers that control the input and output pin configurations and timers that may be used. After initialization is complete the system enters LOW POWER MODE. In LOW POWER MODE the charging function is disabled or OFF. The docking system may stay LOW POWER MODE and loop checking if a sleeve has been docked. When the docking system detects that a sleeve has been docked it will exit LOW POWER MODE and enter CHARGE MODE. The charging function is enabled or turned ON in CHARGE MODE. The firmware will remain in CHARG MODE and loop checking that a sleeve is still docked. If the sleeve remains docked on the docking system then CHARGE MODE will remain ON. If the sleeve is removed from the dock the docking system will return to LOW POWER MODE and the charge function will be turned OFF. The docking system will remain in LOW POWER MODE until a sleeve is docked and the process describe above will repeat indefinitely until power to the docking system is removed.
