| 20090167678 | SYSTEM AND METHOD FOR NAVIGATING A MOBILE DEVICE USER INTERFACE WITH A DIRECTIONAL SENSING DEVICE - An electronic mobile device includes a display, a tilt sensor and a processor. The display is for displaying a graphical element. The tilt sensor is configured to measure a tilt angle of the mobile device. The processor is configured to store the measured tilt angle as a reference tilt angle, subsequently determine a delta tilt angle as the difference between a currently measured tilt angle and the reference tilt angle, compare the delta tilt angle to different thresholds, and alter the position of the displayed element on the display at a rate that is based on the number of the thresholds the delta tilt angle has exceeded. | 07-02-2009 |
| 20090200989 | Method and Apparatus for Handling a Charging State in a Mobile Electronic Device - The present invention is directed at a method of handling a device charging state for a Universal Serial Bus (USB) connected mobile electronic device comprising the steps of sensing a presence of a bus voltage; sensing an enumeration acknowledgement signal between the device and a USB host; and transmitting a signal to instruct the device to enter the device charging state. | 08-13-2009 |
| 20100076678 | MOBILE DEVICE WITH ON-SCREEN OPTICAL NAVIGATION - A mobile computing device, including a main body, a processor and associated memory housed within the main body, a display screen housed within the main body and responsive to signals from the processor, an optical sensor fixed to the main body for capturing successive images and providing image signals representative of the captured images to the processor, and a navigation module associated with the processor for determining, based on the image signals, a relative movement between the main body and a reference surface and moving a pointer on the display screen based on the determined relative movement. | 03-25-2010 |
| 20100102774 | Method and Apparatus for Handling a Charging State in a Mobile Electronic Device - In accordance with the teachings described herein, a method and apparatus for handling a charging state in a mobile electronic device is provided. A universal serial bus (USB) interface may be used for connecting the mobile device to a USB host. A processing device may be used to control operation of the mobile device and receive an enumeration acknowledgement signal from the USB host via the USB interface and generate an enable signal upon receiving the enumeration acknowledgement signal. The method and apparatus may further include a rechargeable battery, a battery charger, a timing circuit, and a battery charger enabling circuit. | 04-29-2010 |
| 20100117595 | Method and Apparatus for Handling a Charging State in a Mobile Electronic Device - A system and method for using a universal serial bus (USB) interface in a mobile device is provided that includes providing a battery charger operable to receive a voltage provided at the USB interface, the battery charger operable for charging a battery in the mobile device, and, a voltage regulator operable to receive a voltage provided at the USB interface, the voltage regulator used in powering the mobile device. The method also includes, detecting a USB bus voltage at the USB interface, measuring passage of a predetermined amount of time upon detecting the USB bus voltage, and disabling at least one of the voltage regulator and the battery charger if the predetermined amount of time expires before an enumeration acknowledgement signal is received at the USB interface. | 05-13-2010 |
| 20100289456 | Method and Apparatus for Handling a Charging State in a Mobile Electronic Device - The present invention is directed at a method of handling a device charging state for a Universal Serial Bus (USB) connected mobile electronic device comprising the steps of sensing a presence of a bus voltage; sensing an enumeration acknowledgement signal between the device and a USB host; and transmitting a signal to instruct the device to enter the device charging state. | 11-18-2010 |

| 20110136485 | SYSTEM AND METHOD FOR SENSITIVITY MEASUREMENT IN WIRELESS MOBILE STATIONS - A system and method is provided for performing a wireless reception performance test between a wireless device and a base station emulator. The method comprises generating a path loss correction factor. The path loss correction factor compensates for path loss from an antenna port of the base station emulator to an antenna port of the wireless device. The method further comprises transmitting from the base station emulator at least a further signal transmission. The further signal transmission includes the path loss correction factor such that the transmission power of the further signal transmission removes the effect of path loss from the wireless reception performance test. | 06-09-2011 |
