Distributed voice user interface
A distributed voice user interface system includes a local device which receives speech input issued from a user. Such speech input may specify a command or a request by the user. The local device performs preliminary processing of the speech input and determines whether it is able to respond to the command or request by itself. If not, the local device initiates communication with a remote system for further processing of the speech input.

Buoyant airbarge and spinnaker sail combinations for generating electric power from wind
InactiveUS20120049533A1Minimal powerMinimal resistanceWind energy with electric storageWind energy with garvitational potential energyWind systemPower cycle
Systems for generating electric power from wind are disclosed, which use buoyant aircraft and spinnaker sails to generate very large pulling forces, which will be used to drive electric generators. The buoyant aircraft, referred to as “airbarges”, will have large, wide, and flat shapes which combine various traits of kites, manta rays, and “flying wing” aircraft. They can be flown “nose up” during the pulling stage of each power cycle, and “nose down” during retrieval. Spinnaker sails are comparable to horizontal parachutes, with tethering systems that will enable them to be pulled back to a starting location in a “luffing flag” or “closed umbrella” configuration. Because of various factors, spinnaker sails can generate much greater power output and operating efficiency than 3-blade wind turbines. “Webbing sails” made from interwoven straps also are disclosed, which can be used even in extremely high winds.

Optical transmitter

In an optical transmitter of the invention, continuous light from a light source is a (CS)RZ-D(Q)PSK modulated by two optical modulators connected in series, and a part of the optical signal output from a post-stage optical modulator is branched by an output monitor section, and the power of a preset frequency component, excluding a frequency component corresponding to a baud rate, included in an electrical spectrum acquired by photoelectrically converting the branched beams is measured. The relative phase of drive signals applied to the optical modulators is then feed-back controlled so that the power becomes a minimum. As a result, a delay shift due to a temperature change or the like between drive signals applied to respective optical modulators, can be reliably compensated.

Self-healing analog-to-digital converters with background calibration
ActiveUS20120206281A1Minimal area overheadMinimal extra areaElectric signal transmission systemsAnalogue-digital convertersMultiplexerFinite-state machine
Calibration of an analog-to-digital converter (ADC) is accomplished via a reference comparator, a first and second multiplexer (MUX), and a finite state machine (FSM). By sampling an analog input with the reference comparator and comparing the results with those of the ADC using the FSM, all the comparators in the ADC can be calibrated without interrupting the ADC's normal operation. The first MUX provides a same reference voltage to the reference comparator as a comparator selected for the calibration, and the second MUX provides the FSM with the output of the selected comparator. The FSM then performs a comparison of the reference comparator and the selected comparator, extracts the polarity of the mismatch, and updates the contents of a memory with the extracted polarity. An offset control in the selected comparator receives a signal corresponding to the extracted polarity stored in the memory and injects offset current into the comparator.

A battery powered ignition and control system for a gas burner includes circuits for controlling a pilot burner, a main burner, a flame sensor and an igniter. Mechanically latched valves, which require power only to switch between and open and closed state are used to control the pilot and main gas. The circuitry spends a majority of time in a powered down state and draws power only when required to interrogate the state of the flame and to perform an ignition sequence as required, as periodically dictated by a watchdog system. The latching valves are electrically pulsed to change state and thus draw very low average power when called upon. Lithium batteries provide system power for a long duration.
