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.

Abstract: A slide actuation apparatus includes a bezel configured to maintain a configuration of the slide actuation apparatus. The bezel also includes an opening on an external surface. The slide actuation apparatus also includes an actuator configured to move within a compartment formed by the opening and a sliding rail configured to guide movements of the actuator along a surface of the sliding rail. The sliding rail is compressible downward in response to movement of the actuator along the surface of the sliding rail. The slide actuation apparatus further includes a slide contact configured to make an electrical connection to a flexible circuit and configured to provide a signal of a change to a circuit board of an attached computing device in response to downward compression of the sliding rail.

Abstract: A light emitting diode (LED) display assembly is formed of a translucent plastic housing, a light diffuser film coupled to the translucent plastic housing, a light barrier gasket coupled to the diffuser film, and an LED module coupled to the light barrier gasket. The LED module comprises a plurality LEDs individually controlled for generating a light source to form a graphic on the surface of the translucent plastic housing.

Abstract: A display system (200) is provided to withstand high impact in conjunction with electrostatic discharge (ESD) protection. The display system (200) comprises a display lens (205) coated with a layer (220) of electrostatic discharge material. The display system (200) further comprises an inner housing layer (210) formed of an insulative material providing structural support to the display lens (205) and an outer housing layer (215) formed of an antistatic material providing an electrical path for dissipating electrostatic charge accumulated on the display lens (205). A portion of the display lens, formed as a flange (225), is mounted between the inner housing layer and the outer housing layer.

Abstract: A housing (100) provides electrostatic discharge protection and structural robustness for a portable communication device. A hybrid formation of an inner housing portion (102) composed a non-ESD material provides for robustness and an outer housing portion (104) formed of ESD material provides improved grounding.

Abstract: A radio device housing uses an exterior layer or surface made of an electrically conductive anti-static material that is formed over an interior or inner layer that is made of a non-conductive material. The anti-static material prevents the accumulation of static charge on the device housing in accordance with intrinsically safe design standards. An antenna portion is formed on a section of the non-conductive material that is not covered by the conductive material. An antenna element is disposed on the antenna portion and coupled to a radio circuit inside the device.
