    Abstract: A method and apparatus for quickly forming a PAN is describe herein. During operation, a modulated vibration will be received that identifies that network formation is to take place. All devices detecting the vibration will be paired/associated to form a PAN. In one embodiment of the present invention a first device generates the vibration and the subset of available devices will form a PAN with the first device acting as a master device within the formed PAN. In another embodiment of the present invention, a piece of clothing (e.g., a vest) is equipped with a haptic module (vibrating circuitry) to generate the vibration. All pieces of equipment attached to the piece of clothing will receive the vibration and pair accordingly.

    Abstract: A portable battery-operated communication device includes a high-speed communication bus, a first high-speed communication processor coupled to the bus and configured for transferring communication signals to a second high-speed communication processor over the bus, and an isolation circuit for the bus with a first terminal coupled to the bus and configured to receive a first communication signal from the first processor via the bus, and a first resistor that is coupled to the first terminal and configured to protect the first terminal from an overcurrent failure condition, in which the isolation circuit is configured to match impendences between the isolation circuit and bus, isolate series inductance associated with the first terminal, protect the first terminal from an overvoltage failure while maintaining signal integrity of the first communication signal, and pass through the first communication signal from the first terminal to a second terminal coupled to the high-speed communication bus.

    Abstract: A holster is provided to receive a radio (mobile communications device). The radio is operatively equipped with a front-facing touchscreen. The holster is equipped with an optical reflector. The optical reflector is adapted to change the direction of light rays passing through it in order to reflect only a portion of the front-facing touchscreen to a top window located within the holster. The top window and the touchscreen are substantially perpendicular to each other. The holster is equipped with at least one capacitive touch extension element that couples the top window to a point on the touchscreen to control an interface element on the touchscreen.

    Abstract: A method and circuitry for detecting a touch on a device is provided herein. Touch-sensing circuitry comprises two antennas coupled to two voltage-controlled oscillators (VCOs). A phase locked loop (PLL) is provided coupled to the VCOs. The PLL compares a VCO output with a frequency source (temperature controlled crystal oscillator (TCXO)), and outputs a tuning voltage (steering voltage) for the VCO that is based on the difference between the VCO frequency and the TCXO frequency. The steering voltages for each VCO are compared, and a decision is made as to whether or not a touch has been made to the antennas. If the antennas have been touched, a location of the touch is determined based on a difference in the steering voltages of the two VCOs.
