Abstract: A push button for a control panel. The push button includes a button body and a reflector molded as a single, monolithic piece with links extending between the button body and the reflector. A divider of the button body is between a first light source of a printed circuit board and an indicator light guide of the button body. The divider restricts light from the first light source from illuminating the indicator light guide.

The digital data interface device can be used to control a peripheral device, such as a camera, bar code reader, image scanner, audio device or other sensor. In one example, a cellular telephone having a camera with an MDDI link and a digital data device interface is provided.

Abstract: A method, apparatus, and computer program product embodied on a hardware computer readable storage medium for compensating mismatched delays in at least two signals of a mobile display digital interface (MDDI) system. The method, apparatus, and computer program product embodied on a hardware computer readable storage medium sends a skew calibration packet from a host to a client. The host begins a calibration pattern; then toggling a data signal and a strobe signal at a substantially similar time which strobe signal is used by the client as a clock source. The method, apparatus, and computer program product embodied on a hardware computer readable storage medium also aligns a timing of the strobe signal and the data signal by providing varying delays and resetting the client to an original clock source before a next packet reception.

Abstract: A memory tracking circuit controls discharge duration of a tracking bit-line based on (i) a signal received at the far end of a tracking row after a propagation delay and (ii) a signal applied to a transistor-based gate delay. The tracking circuit (i) extends the discharge duration when one or more of (a) the propagation delay and (b) the transistor-based gate delay is shorter than an uncontrolled discharge duration of the tracking bit-line, and (ii) does not extend the discharge duration otherwise. Based on the discharge duration, the tracking circuit activates a reset signal that resets a clock-pulse generator to switch the memory from an access operation to a recess state. Controlling the discharge duration, and consequently the reset signal, based on the propagation delay and the gate delay allows the clock-pulse generator to adjust access times to account for the memory array configuration and process, temperature, and voltage conditions.

Abstract: A data Interface for transferring digital data between a host and a client over a communication path using packet structures linked together to form a communication protocol for communicating a pre-selected set of digital control and presentation data. The signal protocol is used by link controllers configured to generate, transmit, and receive packets forming the communications protocol, and to form digital data into one or more types of data packets, with at least one residing in the host device and being coupled to the client through the communications path. The interface provides a cost-effective, low power, bi-directional, high-speed data transfer mechanism over a short-range “serial” type data link, which lends itself to implementation with miniature connectors and thin flexible cables which are especially useful in connecting display elements such as wearable micro-displays to portable computers and wireless communication devices.

Abstract: A double data rate serial encoder is provided. The serial encoder comprises a mux having a plurality of inputs, a plurality of latches coupled to the inputs of the mux, an enabler to enable the latches to update their data inputs, and a counter to select one of the plurality of inputs of the mux for output. In another aspect, the mux provides a glitch-less output during input transitions. The mux includes an output selection algorithm optimized based on a priori knowledge of an input selection sequence provided by the counter.

Abstract: The present invention provides systems and methods for adaptive digital data transmission rate control. A digital data transmission system for adaptively transferring packets over a transmission link includes a client device having a bandwidth control module and a host device coupled to the client device over the transmission link. The host device includes one or more bandwidth control registers and a packet builder. The bandwidth control module determines a packet speed and/or size for packets transmitted from the host device to the client device over the transmission link. The bandwidth control registers store the requested packet size and/or rate. The packet builder accesses these registers when transmitting packets to determine the requested packet size and/or rate.
