Abstract: An embedded processor system having a single-chip embedded microprocessor with analog and digital electrical interfaces to external systems. A novel processor core uses pipelined execution of multiple independent or dependent concurrent threads, together with supervisory control for monitoring and controlling the processor thread state and access to other components. The pipeline enables simultaneous execution of multiple threads by selectively avoiding memory or peripheral access conflicts through the types of pipeline stages chosen and the use of dual and tri-port memory techniques. The single processor core executes one or multiple instruction streams on multiple data streams in various combinations under the control of single or multiple threads.

Abstract: A logic circuit is provided that implements soft error detection and recovery for protecting the logic circuit from the negative effects of soft errors caused by single event upsets. The logic circuit may include a configurable processing module, an input buffer, an output buffer, a configuration and scrub control module and a buffer control module. The configuration memory of the configurable processing element may be periodically read and checked for errors. If an error is detected, the configurable processing element may be at least partially reloaded, the output data produced since the last checking operation is discarded, and the input data may be reprocessed by the reloaded processing element. If no error is detected, then the output data may be marked for release and processing continues. Additionally, the logic circuit may include error checking of the input buffer, the output buffer and control logic to ensure that the logic circuit has complete soft error detection and recovery capability.

Abstract: A system for extracting samples from a stream in a conduit utilizing a probe, placed in the stream and having a channel for passing samples from the conduit stream. First and second pressure taps measure the pressure inside and outside the probe. A feedback signal, based on a pressure differential relative to the probe, is generated and controls a valve regulating sample velocity flow through the probe channel, that bears a fixed proportion to the velocity of flow in the conduit. The constant of proportionality between flow velocities in the conduit and the probe may be 1.0, resulting in an isokinetic sampling condition.

The supersonic exhaust nozzle is configured with a variable exhaust expansion ratio.

Abstract: A novel control system for image input device, especially fingerprint image input device, is disclosed. The control system comprises a fingerprint image input device selection module, an instruction conversion module and a fingerprint image size determination module. The fingerprint image input device selection module selects a particular fingerprint image input device from a variety of fingerprint image input devices. The instruction conversion module generates, upon an image capture instruction or a match instruction from a fingerprint verification software, particular image capture instructions to a the selected fingerprint image input device, wherein the instruction pertains to a specification of image as selected by a user or determined with a particular method. The fingerprint image size determination module determines the specification, including the resolution and the size of fingerprint image to be captured.

Abstract: An energy absorbing knee bolster for use in an interior of a vehicle is disclosed. The knee bolster is configured to absorb energy from the vehicle's occupants during a crash.
