20140091752 | USB Charging System - A dual USB port charging system that can charge at 2.1 A and also at 1 A at the same time when the power supply is only capable of 10 W. A USB port is set as a 2.1 A port via resistor network. If nothing is connected to the other USB port, it charges at 2.1 A. If a device is connected to the other USB port, it automatically detects this condition and momentarily interrupts the 5V output while resetting the USB port to 1 A (the resistor network is changed to 1 A spec). Both devices will then charge at 1 A. If the second device is disconnected while the first device is still charging at 1 A, the charging system will interrupt the output momentarily and reset the network back to 2.1 A. The first device re-registers and is now able to charge at 2.1 A again. If the second USB device is connected first while the first USB port is unused it will also set both ports as 1 A. As the standard USB port is switched between 1 A and 2.1 A network, the current limit is also automatically switched from 1 A to 2.1 A. | 04-03-2014 |

The remote motion sensor is operated by the operator's hand motion near the sensor without contacting the sensor. The remote motion sensor may be detachable from the vehicle power adapter. The operator's hand motions are translated into control signals and sent to a portable electronic device to control its functions. The control signals may be sent through a wire or wirelessly through a wireless transmitter. | 02-09-2012 |
20120028484 | Automatic Sliding Door - An automatic cover for universal serial bus (USB) port that opens and closes automatically when a USB plug is inserted and removed from the USB port. The automatic sliding door for a universal serial bus comprises a top door, a biasing means to urge the top door downward, a bottom door, a biasing means to urge the bottom door upward, and a support structure to which the top door and the bottom door are pivotally affixed.

20120019392 | USB Charger - A USB charger comprises a power input, a microprocessor, a resistor network, and a USB port for charging electronic devices through the USB port. The USB charger defaults to provide 2000 mA when power is applied through the power input. When a device is detected at the USB port, it measures device current drain to determine if it is charging. If the device is charging, then it remains in the 2000 mA charging mode. If no current drain is detected, the power supply switches to 1000 mA. If the electronic device recognizes the proper charging network it will begin charging. When the microprocessor detects current drain, it leaves the charging network as is. If still no current drain is detected, the USB microprocessor will attempt the 500 mA charging current. If there is a current drain, it will leave the charging network as is. If no current drain is detected, then it indicates a fault and a LED flashes to indicate the fault. | 01-26-2012 |
