A wireless communication device, comprising one or more intra-device modules, an internet protocol (IP) router for providing inter-device connectivity between a host and the intra-device modules, and one or more transport mechanisms, for coupling the IP router to the host. One or more intra-device modules are accessed via a standard internetwork protocol as if the intra-device modules were local servers.

Adaptive transport TCP/IP phone management

A keypad that produces a voltage level indicative of a key pressed and a touch panel that produces a voltage level indicative of a location on the touch panel that has been pressed are both coupled to the input of an analog-to-digital converter (ADC). A processor, coupled to the output of the ADC, reads the ADC output.

ADC sharing for keypad and tough panel of a phone

A detection circuit that detects the open and close state of a flip cover of a communications device. The detection circuit includes a resistive network and an analog-to-digital converter (ADC). When the flip cover is in the closed position, the circuit detects a unique resistive value through a set of contacts. This voltage level is converted from an analog signal to a digital signal via the ADC for input into a microprocessor. When the flip cover is in the open position, the contacts are broken, thus, disabling the detection of the unique resistive value. The resulting voltage level is converted from an analog signal to a digital signal via the ADC for input into a microprocessor. Software, programmed within the microprocessor, enables the communications device to operate in the appropriate mode according to the detection of the open/close state of the flip cover.

Detection of flip closure state of a flip phone

A flip cover and hinge operate as a rotary switch to select the mode of operation of a communications device. Multiple contacts are located on the sides of the inner surface of the flip cover and a single contact is located on each side of the body of the communications device. Each contact located on the sides of the inner surface of the flip cover represents a different mode of operation for the communications device. As the flip cover rotates from a closure position to its final position as a stand, the mode of operation of the communications device changes as the contact from the body of the communications device connects with one of the contacts on the flip cover. Three modes of operation are presently implemented: the KEYPAD mode, the SMARTPHONE mode, and the SPEAKERPHONE mode.

Selecting flip phone operating mode using flip position

A method and apparatus for calibrating a resistive ladder switching matrix coupled to a keypad in a portable electronic device having a housing with a cover that may be positioned in an open state or a closed state. A first contact of a calibration element is coupled to a reference voltage and a second contact of the calibration element is coupled to ground by moving the cover from the open state to the closed state. When the first contact of the calibration element is coupled to the reference voltage and the second contact of the calibration element is coupled to ground, a calibration resistance across the calibration element is determined. The calibration resistance may correspond to an input impedance of the resistive ladder switching matrix when no buttons associated with the keypad are depressed. Signals from the resistive ladder switching network are calibrated when the cover is in the closed state in accordance with the calibration resistance.
