Electronic probe handle

Disclosed is a mobile device comprising a voltage supervisor and reset (VSAR) module configured to detect an input voltage, start a timer set to a predetermined time period responsive to detecting the input voltage, and output a low signal responsive to detecting the input voltage. The mobile device also comprises a battery charger module configured to receive the input voltage, receive the low signal, output a power signal, and charge a battery. The mobile device also comprises a processing module configured to receive the power signal, and attempt enumeration responsive to receiving the power signal, wherein the VSAR module is further configured to output a high signal to the battery charger module when the timer expires and enumeration has not been completed.

Method and apparatus for handling a charging state in a mobile electronic device

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.

Mobile device with on-screen optical navigation

An electronic mobile device that includes a controller including at least one processor, for controlling operation of the mobile device, a display coupled to the controller, and a navigational input mechanism coupled to the controller and responsive to user manipulation thereof. The controller, in one input mode, moves a selection marker on a user interface screen on the display in response to user manipulation of the navigational input mechanism, and in a second input mode, authenticates a user of the device in dependence on a sequence of input events resulting from user manipulation of the navigational input mechanism matching a predetermined passcode sequence.

Touch entry of password on a mobile device

An electronic mobile device includes a display for displaying a graphical element. A tilt sensor is configured to sense first and second tilt angles of the mobile device. A processor is coupled to the display and the tilt sensor and configured to move the graphical element relative to the display in a first direction based on the first tilt angle, and to move the graphical element relative to the display in a second direction based on the second tilt angle.

System and method for navigating a mobile device user interface with a directional sensing device

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.

System and method for sensitivity measurement in wireless mobile stations

Systems and methods of providing power through a Universal Serial Bus connector are provided. A charging system comprises an interface configured to receive power, a power converter coupled to the power source interface, the power converter configured to use the received power to generate power output, and a charging controller configured to control an amount of power provided at the USB connector on the power lines derived from the power output, and configured to generate an identification signal on the USB connector's two data lines, the identification signal usable to indicate the charger is not subject to standard USB power limitations, the identification signal provided through the use of a resistance between the D+ and D&#x2212; data lines.

Charger system and method

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.

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.
