An apparatus for generating a data signal comprises a processing circuit configured to generate the data signal, the data signal comprising a sequence of a first signal edge of a first type, a second signal edge of a second type, and a third signal edge of the first type, the first signal edge and the second signal edge being separated by a first time period corresponding to first data to be transmitted, and the second signal edge and the third signal edge being separated by a second time period corresponding to second data to be transmitted. An output interface circuit is configured to output the data signal.

A sensor comprises a transmitter to transmit signals over a communication path, the sensor further capable to receive signals from the communication path, wherein the sensor is configured to communicate sensor data having a nibble data signal format at the transmitter in response to a trigger signal received at the sensor.

Input/output (I/O) operation requests from pageable storage mode guests are interpreted without host intervention. In a pageable mode virtual environment, requests issued by pageable storage mode guests are processed by one or more processors of the environment absent intervention from one or more hosts of the environment. Processing of the requests includes manipulating, by at least one processor on behalf of the guests, buffer state information stored in host storage. The manipulating is performed via instructions initiated by the guests and processed by one or more of the processors.

Efficient codeword synchronization methods and systems for fiber channel protocol are disclosed. The method includes identifying a codeword boundary by detecting 100-bit known patterns in a bit codeword in a transmission.

An antenna array is steered electronically by controlling the transmission speed of the RF signal in feed line of each radiator in the array. The transmission speed is controlled using phase shifters, that include variable dielectric constant (VDC) material causing the change in transmission speed. The control signal applied to the VDC material generates the required phase shift. The control signal is calculated for each phase shifter in real time for each control cycle, so as to enable the main beam to track a target, such as a satellite. The control signal is a square wave signal, and each control signal has a specifically calculated duty cycle or frequency to generate the required phase shift.

The transmission unit includes a modulation unit that generates a PWM signal having a predetermined duty ratio, an output unit that outputs the PWM signal, a feedback unit that feedbacks the PWM signal, and a transmission controller that controls the modulation unit using the feedbacked signal. The receiving unit includes a reception controller that determined whether to drive a load based on the PWM signal and a switching unit that is turned on or turned off based on the determination of the reception controller.

One embodiment provides haptic functionality. The embodiment receives an encoded value that encodes an actuator drive value, where the actuator drive value corresponds to a strength of a haptic effect. The embodiment converts the encoded value into a pattern of ON/OFF durations, and plays back the pattern of ON/OFF durations on an actuator to produce the haptic effect.

Systems, methods, and apparatus are described that enable a device to indicate availability of priority data to be communicated over a half-duplex serial bus without waiting for an ongoing transmission to be completed. In-datagram critical signaling is accommodated without breaking backward compatibility. A method implemented at a transmitting device coupled to a serial bus includes transmitting a data byte over a first line of the serial bus to a receiving device in accordance with a clock signal transmitted by a master device on a second line of the serial device, detecting a first pulse on the first line of the serial bus during a cycle of the clock signal designated for an acknowledgement or negative acknowledgement by the second device, and processing an alert indicated by the first pulse.
