Abstract: The attitude of a tiltable body is tracked and controlled on the basis of signals outputted from gyros and tilt sensors. The signals outputted from the gyros are transformed and integrated to produ ce estimated position information in the form of a modified quaternion in which the yaw component is constrained to a zero valu e. Modified quaternion information in the same form is also generated from signals outputted from the tilt sensor and is used to detect and correct an error component in the estimated position information. Gyro drift is also corrected based on the output of th e tilt sensor.

Title: Highly accurate digital to analog converter
Inventor: PAQUET FRANCOIS J
IPC: H03M1/66
Filed: 2002-09-06
Granted: 2009-06-30
Abstract: The present invention relates to a highly accurate D/A converter. The converter comprises four main building blocks - in logical order of their operation - a DC processing circuit, an analog switching device, a bootstrap circuit, and a third order low-pass filter. The boots trap circuit is interposed between the switching device and the low-pass filter for substantially reducing loading created by the low-pass filter circuit and acting on the switching device. Furthermore, a new modulation scheme is used to eliminate cross-over discontinuity in the continuous analog signal by interposing between each two successive pulses a cross-over correction pulse having opposite polarity and a predetermined fixed pulse- width. The relatively simple circuit is capable of being implemented with parts that are readily available, and more particularly parts that are readily available in radiation hardened versions for space applications such as control of gyroscopes and accelerometers in satellites.

Granted: 2007-01-02
Abstract: The invention comprises a cog type belt having a plurality of transverse teeth (5) on an inner surface. The belt comprises an outer extensible elastomeric layer (8), an inner compression layer and a tensile member (9). Each tooth further comprises a non-metallic or plastic transverse member, pillar or rod (10) that extends across the width of each tooth (5). The opposing outer surfaces of each transverse member are inclined to each other and each end approximately equates to an outer surface of the belt body elastomeric. A  compressive load between the sheaves is carried by the rod and the sidewall in proportion to the modulus of each component. The transverse members have pegs or legs (12, 14) that allow proper spatial orientation of each transverse member in each tooth during the fabrication process, thus assuring proper operating characteristics, including proper alignment within a pulley.

Abstract: A line-up clamp unit is powered by a diesel engine which drives a hydraulic pump for operating hydraulic equipment in the unit. The unit includes a line-up clamp which has front shoes, rear shoes and expanding copper back-up tiles. Drive wheels are deployed by a hydraulic cylinder and operated by a hydraulic drive motor.  Brakes are also operated hydraulically. A group of aligning assemblies are electrically operated and function to extend L-shaped members to beyond the diameter of the pipe being welded so that the unit can be retracted and automatically positioned at the end of a pipe section.  A control box is mounted to the line-up unit and includes a radio receiver for receiving control signals and producing corresponding electric control commands for operating the hydraulic and electric components of the line-up unit. A remote control radio transmitter has operating mechanisms, including push buttons and toggle switches, for operating the multiple operative elements of the line-up unit, including the engine, drive motor, brakes, line-up clamp and aligners. By using the remote control unit and transmitting the control signals by radio signal to the receiver in the control box of the unit, there is no need for a reach rod or tether for moving, positioning and operating a line-up clamp. The use of a radio control unit as described reduces the time required for positioning and operating a line-up clamp unit in welding pipe sections to construct a pipeline.

Abstract: A multichannel hearing aid (20) comprises at least one frequency channel having a compressor (38) with a compression threshold at an output level bel ow the hearing threshold and an attack time above 0.5 seconds whereby hearing o f a sudden sound in a stationary sound environment is facilitated. With this compressor, the amplification of low signal levels may be increased compared to the prior art, as the compressor kicks in to generally suppress steady noises. The gain may generally be increased as high as feasible in view of t he microphone baseline noise, which should preferably be kept below the hearing threshold. Thus the user of the hearing aid will generally have the option o f a higher gain of low level sounds than generally feasible with prior art hearing aids.

Abstract: An implementation, as described herein, facilitates fast start-up of a new media stream while avoiding temporal interruption (i.e., "hiccups") of the presentation of that new media stream. At least one implementation, described herein, coordinates the delivery of multiple simultaneous media streams on a media-stream network. Its coordination accounts for traversal of bandwidth- restricted chokepoints; quickly stopping delivery of one or more media streams from the set of streams; quickly initiating delivery and presentation of one or more new media streams not previously in the set (i.e., a "channel change"); and producing clean playback of all of the streams in the set, despite their different timelines. This abstract itself is not intended to limit the scope of this patent. The scope of the present invention is pointed out in the appending claims.
