DETAILED DESCRIPTION
Power may be provided from a host device through a powered USB cable to one or more peripheral devices. However, these powered USB cables are limited by the individual connector power limits prescribed by regulations. As such, each powered USB socket connection provides a key position location corresponding to each level of voltage to deliver to the one or more peripheral devices. The different levels of voltage correspond to the various types of powered USB cables.
One solution is to provide a mechanical barrier to physically block at least a portion of the connector. In this solution a movable barrier is positioned by a user to create the different types of socket structures to deliver the corresponding voltage level. However, this solution requires the barrier to be accessible and controlled by the user to create the socket structure to deliver the corresponding voltage. Further, this solution lacks automation for the host device to detect the type of socket structure to deliver the corresponding voltage. For example, the user moves the mechanical barrier to create a 12 volt powered USB socket connection and to another location to create a 24 volt powered USB socket connection. Additionally, this solution requires much space and design on the host device to incorporate the mechanical barrier.
In another solution, power and communications are delivered on separate USB cables. In this solution, the USB socket delivers communications on a separate socket connection than the power socket. Further, this solution lacks a universal USB connection socket to deliver power and communications through the USB cable. Additionally, this solution requires the use of a separate USB cables to receive both USB data communications and power. Further, this solution also takes up much space on the host device as two different socket connections are required for the data communications and the power delivery.
To address these issues, example embodiments disclosed herein provide a computing system comprising a host device with a connection socket to support multiple types of cables through detecting key positions. This embodiment enables the connection socket to accept and support multiple types of cables providing an aspect of universality to the connection socket. Detecting the key positions enables the host device to determine the type of cable. For example, the key position in the connection socket for a 12 volt powered USB cable is in a different location from the key position for a 24 volt powered USB cable. Rather than requiring different connection sockets, the connection socket supports multiple voltage versions by detecting the key positions to determine that type of version's voltage. Utilizing two key positions enables the host device to identify a type of cable from two or more types of the cables.
Additionally, the host device determines the impedance of each key position. The impedance is a measurement of opposition between each of the key positions in the connection socket on the host device to that of the USB cable. Determining the impedance of each key position provides an auto-detection of the key positions, by measuring the connection between the USB cable and the host device. Further this provides also provides an efficient aspect as it requires no user input.
In another embodiment, the system comprises a switching circuit to determine a logic state of each of the key positions to deliver a power associated with the type of cable based on the logic states. Utilizing the logic states, the switching circuit may switch between various power levels providing additional efficiency
In a further embodiment, the switching circuit turns off the power (i.e., delivers 0 volts) if it is determined both key positions are activated in the connection socket. Delivering 0 volts provides a safety aspect to prevent voltage and/or power delivery to the peripheral device on the type of cable which may have mechanical failure as inserted into the connection socket. Preventing power delivery prevents additional damage to the USB cable and/or peripheral device when the cable and/or connection socket may suffer a mechanical failure.
Yet, in a further embodiment, the switching circuit includes multiple semiconductors to obtain the logic states of each of the key positions. Utilizing semiconductors enables the host device to utilize internal circuitry to assign logic states to the key positions without the use of an external device which may increase cost, design, and space.
In summary, example embodiments disclosed herein provide a universal powered USB connection socket to detect the type of USB cable and to deliver the corresponding voltage. Further, example embodiments save time and space by providing a universal connection for multiple types of USB cables. In addition, examples provide a connection socket to detect the type of cable for cables other than USB cables.
Referring now to the drawings, FIG. 1 is a block diagram of an example host device 102 including a connection socket 104 with a first key position 106 and a second key position 108, the key positions 106 and 108 determine a type of cable. Additionally, the host device 102 includes a switching circuit 110 to determine a logic state 112 for each of the key positions 106 and 108 to deliver power 114 associated with the type of cable based on the logic states 112. The host device 102 is an electronic device that is programmed to carry out tasks and/or operations. Specifically, the host device 102 is considered an electronic device including a powered universal serial bus connection interface to deliver communication data and/or power 114 over a universal serial bus cable to one or more peripheral devices. In this embodiment, the universal serial bus connection allows for a higher powered device (i.e., peripheral device) to obtain its power through the host device 102 rather than requiring an independent power supply and/or adapter. As such, embodiments of the host device 102 include a computing device, client device, personal computer, desktop computer, laptop, a mobile device, a tablet, a video game console, or other electronic device suitable capable of including a connection socket 104 to detect key positions 106 and 108 to determine the type of corresponding cable. In another embodiment, the host device 102 is a point of sale device supplying power 114 in addition to the data communication to peripheral devices, such as receipt printer, barcode readers, printers, scanners, etc.

Further, the connection socket 104 communicates with the switching circuit to output the power 114 based on the logic states 112 to one or more peripheral devices. The connection socket 104 is designed to standardize the connection between a USB cable and the host device 102 for communication and/or power 114. The connection socket 104 is a type of electro-mechanical device that joins a cable with the host device 102 to enable data communication and power.

The key positions 106 and 108 within the socket connection 104 correspond to features that identify the type of cable. Specifically, on an end of the cable, there is a plug and/or connector which contains one or more features to correspond to the key positions 106 and 108. In this embodiment, the key positions 106 and 108 are mechanical attributes that respond to the features in the cable in various locations that form a pattern indicating the type of cable. For example, these mechanical attributes correspond to features within the type of cable being plugged into the connection socket 104 and may include pins, spring triggers, etc. to enable the socket connection 104 identify that type of cable. In this regard, detecting the key positions 106 and 108 provides the connection socket 104 to detect the type of cable other than USB cables. In one embodiment, the key positions 106 and 108 correspond to features on the type of cable to indicate which level of voltage to deliver. In a further embodiment, the key positions 106 and 108 may include a third and fourth key position, each key position located in a separate location and each indicating the type of USB cable. This embodiment may be explained in further detail in FIG. 3B. Embodiments of the key positions 106 and 108 include pins, spring triggers, switches, triggers, or other type of mechanical attributes within the connection socket 104 to identify the type of cable. As depicted in FIG. 1, both the key positions 106 and 108 communicate with the switching circuit 110 to signal which key positions 106 and 108 are being used with the type of cable. Further, utilizing the two key positions 106 and 108 enables the connection socket 104 to support two or more types of cables.
The switching circuit 110 switches between various powered USB cables based on the logic states 112 to deliver the power 114 corresponding to that type of cable. In this embodiment, the switching circuit 110 assigns logic states 112 corresponding to the type of powered USB cable to auto switch the voltage based on the type of powered USB cable which is plugged into the connection socket 104. In another embodiment, the switching circuit 110 may turn off the power 114 (i.e., deliver 0 volts) if it is determined both key positions 106 and 108 are plugged into the connection socket 104. This is a safety feature to prevent voltage on an incorrect connection. In a further embodiment, the switching circuit may include multiple semiconductors and/or switches to assign logic states 112 to delivery of the power 114.
The logic states 112 are representations of a finite number of states that signal to the switching circuit 110 which level of power 114 to provide based on the type of cable detected through the key positions 106 and 108. In one embodiment, the logic states 112 are assigned bits of data to signal to which level power 114 to deliver. This embodiment is described in further detail in FIG. 3B. The logic states 112 may include binary states, Boolean logic, high, low, high-impedance, low impedance, voltage difference between the signal and a reference point, or other type of state to signal which level of power 114 to deliver to one or more peripheral devices.
The power 114 provides electrical energy from the host device 102 to one or more peripheral devices based on the logic states 112. Additionally, the power 114 is considered associated with the type of cable as determined by the key positions 106 and 108. For example, the type of powered USB cable may include 12 volts, thus the key positions 106 and 108 will be in a different pattern compared to a 24 volt powered USB cable, etc. Embodiments of the power 114 include watts, current, electrical change, watts, alternating current, direct current, voltage, analog voltage, digital voltage, or other type electrical energy capable of being supplied from the host device 102.

Further, in this embodiment, the connection socket 204, includes two connections stacked such that one of the connectors accepts the USB plug and the other connector accepts a power plug. Additionally, this embodiment enables various voltages on the cable 216. For example, the various voltages may include 5 volts, 12 volts, and/or 24 volts and as such, the plug and/or connector may be keyed with three different pattern variations, so the host device 202 will only accept connections requiring that version's voltage.

FIG. 3A is an example connection socket with various locations of the key positions 304, 306, 308, and 310, each location of the key position 304-310 corresponds to a different type of cable.
The various locations of the key positions 304-310 are each considered a different pattern representing a different type of cable. In this embodiment, each of the key position locations 304-310 represents each of the key positions, respectively. For example, key position location 304 represents the first key position, the key position location 306 represents the second key position, the key position location 308 represents the third key position, and the key position location 310 represents the fourth key position. Each of these key position locations 304-310 represent the different type of cable. The different types of cable may correspond to various power levels delivered to a peripheral device. For example, key position location 304 may represent 12 volts, key position location 306 represents 24 volts, key position location 308 represents 5 volts, and key position location represents 0 volts. Thus, in this example, when a corresponding feature on that different type of cable, such as a pin is inserted into key position 304, this cable is identified as the 12 volt cable. Further, although FIG. 3 depicts each of the various key locations 304-310 being located in the top of each connection, embodiments should not be limited to this illustration as the various key position locations 304-310 may be towards the bottom, side, and/or any combination of adjacent locations. Additionally, each of the key positions 304-310 are associated with logic states 314-322 to deliver the corresponding power 322 from the host device to the peripheral device.
FIG. 3B is a data arrangement of an example table 312 of each of the key position locations 304-310 as in FIG. 3A with the corresponding logic states 314-320 and power 322.
The logic states 314-320 are representations of the finite number of states that signal which level of power 322 to deliver from the host device to the peripheral device. For example, the first key position 304 corresponds to “Position 1,” accordingly, the “1” is a logic state 314 which indicates the first key position is activated, while the other key position locations 306-310 are inactive as indicated with a “0” logic state. Thus, the corresponding power level 322 to deliver associated with that type of cable based on the logic state of “1” is 12 volts. In another example, the third key position location 308 corresponds to “Position 3,” activating a “1” logic state while the first, second, and fourth key position locations 304, 306, and 310 are inactive and thus delivers 5 volts. Additionally, although FIG. 3B illustrates the logic states 314-320 as binary bits, embodiments should be limited to this illustration as it may include impedance or other type of data to indicate the level of power 322 to deliver corresponding to the type of cable.
The power 322 represents various voltage levels corresponding to the types of cables as identified from the key position locations 304-310. Although FIG. 3B, power 322 representing each of the different types of cables with the corresponding voltage level, embodiments should not be limited to this illustration as the power 322 may include various current levels, watts, or other type of electrical energy.
FIG. 4 is a block diagram of example computing device 400 including a processor 402 to detect key positions, determine a logic state of each key position to then deliver the power associated with a type of USB cable from the host device to a peripheral device. Although the computing device 400 includes processor 402 and machine-readable storage medium 404, it may also include other components that would be suitable to one skilled in the art.

Specifically, the processor 402 executes: instructions 406 to detect key positions to identify a type of cable; instructions 408 to determine an impedance of each of the key positions; instructions 410 to determine the logic states of the key positions to deliver power; and instructions 412 to deliver power associated with the type of cable from the host device to the peripheral device. Embodiments of the processor 402 include a controller, microchip, chipset, electronic circuit, microprocessor, semiconductor, microcontroller, central processing unit (CPU), graphics processing unit (GPU), visual processing unit (VPU), or other programmable device capable of executing instructions 406-412.
The machine-readable storage medium 404 may include instructions 406, 408, 410, and 412 for the processor 402 to fetch, decode, and execute. The machine-readable storage medium 404 may be an electronic, magnetic, optical, memory, storage, flash-drive, or other physical device that contains or stores executable instructions. Thus, the machine-readable storage medium 404 may include, for example, Random Access Memory (RAM), an Electrically Erasable Programmable Read-Only Memory (EEPROM), a storage drive, a memory cache, network storage, a Compact Disc Read Only Memory (CDROM) and the like. As such, the machine-readable storage medium 404 may include an application and/or firmware which can be utilized independently and/or in conjunction with the processor 402 to fetch, decode, and/or execute instructions of the machine-readable storage medium 404. The application and/or firmware may be stored on the machine-readable storage medium 404 and/or stored on another location of the computing device 400.
Instructions 406 detect the key positions of a USB cable. In another embodiment, instructions 406 detect the key positions of the USB cable by obtaining an impedance measurement of each of the key positions.
Instructions 408 determine an impedance of each of the key positions detected at instructions 406. Impedance is a measure of opposition between each of the key positions in a connection socket of a host device and the USB cable. In this regard, when the key position is plugged in, the impedance measurement of that key position will be minimal, indicating a connection between the USB cable and the host device. This connection indicates the type of USB cable plugged into the connection socket.
Instructions 410 determine logic states of each of the key positions to deliver power. In one embodiment, the logic states are determined by multiple semiconductors, such as transistors. In another embodiment, the logic states are determined through multiple switches for the host device to deliver power at instructions 412. Determining logic states enables the host device to switch between the various levels of power corresponding to the types of the powered USB cables. The logic states further correspond to the type of USB cable to deliver the corresponding power. For example, logic states may include switches to connect and deliver 12 volts or 24 volts of power.
Instructions 412 deliver power to the peripheral device. In another embodiment, instructions 412 deliver voltage corresponding to the type of the USB cable as detected from the key positions at instructions 406.
FIG. 5 is a flowchart of an example method performed on a computing device to detect key positions indicate a type of universal serial bus cable, obtain an impedance measurement of each key position, determine a logic state of each key position, if the logic states are similar, the computing devices delivers no power, otherwise the computing device delivers the power associated with the type of USB cable, and delivers voltage corresponding to the type of USB cable. Although FIG. 5 is described as being performed on computing device 102, 202, and 400 as in FIGS. 1-2, and 4, it may also be executed on other suitable components. For example, FIG. 5 may be implemented in the form of executable instructions on a machine-readable storage medium, such as machine-readable storage medium 404 in FIG. 4.

At operation 504, the computing device obtains the impedance measurement of each of the key positions detected at operation 502. In this embodiment of operation 504, each type of powered USB cable is indicated as for the key positions, so the first key position has a corresponding feature in the USB cable. When the USB cable is connected, the measure of opposition between the first key position and the feature will be minimal, thus a socket may continue the connection from the USB cable to the host device.
At operation 506, the computing device determines the logic state for each of key positions as detected at operation 502. Determining the logic state, enables a logic state circuit to auto-switch between the different types of powered USB cables.
At operation 508, if the logic states as determined at operation 506, the computing device delivers no power. For example, the logic states of the key positions may both include logic highs, however, this indicates the key positions detected at operation 502 have a mechanical failure. Preventing power delivery at operation 508 prevents additional damage to the cable and/or computing device once the cable and/or socket connection on the computing device may be suffering a mechanical failure.
At operation 510, the computing device delivers power associated with the type of USB cable to a peripheral device. In another embodiment of operation 510, the computing device converts the power into a voltage to deliver to the peripheral device.
