Abstract: A touch sensitive mechanical keyboard configured to enable a standard look and feel mechanical keyboard to sense fine hand/finger motion over the surface of the keys. Command and cursor input (e.g., pointing and gestures) can be received from the user on the touch sensitive mechanical keyboard without requiring the user to move the user's hand off the keyboard. Fine hand/finger motion detection can be enabled by embedding clusters of capacitive sensors near the surface of the keyboard's keys. The touch sensitive mechanical keyboard can operate in two or more modes—e.g., a typing mode and a mouse mode—and operating the keyboard in mouse mode or switching between the modes can be facilitated by holding (depressing and holding) or tapping (depressing and releasing) arbitrary combinations of keys, or by detecting the number of fingers touching the touch sensitive mechanical keyboard.

Abstract: Embodiments relate to functional test methods useful for fabricating products containing Light Emitting Diode (LED) structures. In particular, LED arrays are functionally tested by injecting current via a displacement current coupling device using a field plate comprising of an electrode and insulator placed in close proximity to the LED array. A controlled voltage waveform is then applied to the field plate electrode to excite the LED devices in parallel for high-throughput. A camera records the individual light emission resulting from the electrical excitation to yield a function test of a plurality of LED devices. Changing the voltage conditions can excite the LEDs at differing current density levels to functionally measure external quantum efficiency and other important device functional parameters.

Abstract: A measurement gap enhancement method is disclosed for use in both synchronous and asynchronous networks. The measurement gap enhancement method employs a first measurement gap pattern, suitable for synchronous networks, including measurement gaps that are of shorter duration and available for more frequency measurements than in legacy implementations. The measurement gap enhancement method also employs a second measurement gap pattern, which also includes short duration measurement gaps, but is also characterized by flexible measurement gap repetition periods suited to asynchronous networks. The first and second measurement gap patterns are made known to an user equipment by way of novel information elements used during RRC connection reconfiguration by the enhanced NodeB base station. The measurement gap enhancement method enables the user equipment to maintain its radio frequency setting between measurements, particularly automatic gain control.
