Abstract: An article carrier comprises a crossbar (16) to be detachably engaged with carrier rails (18, 20) secured to a motor vehicle body panel (12). The longitudinal rails may be aligned to correspond with style lines of the body panel and need not be aligned parallel to each other in order to receive the crossbar. The crossbar (16) includes an elongated rail (22) carrying at least one slider (24), the slider having an end removably engageable with the longitudinal rail. A guide carries the slider along an elongated rail of the crossbar while a latch fixedly locates the position of the slider along the elongated rail of the crossbar. In addition a lock retains the latch in an engaged position to restrict manual operation of the latch. In the preferred embodiment, the longitudinal rails include a track adapted to accommodate correspondingly conforming ends on the slider.

Granted: 2001-07-24
Abstract: A control valve system has two valve trains each of which has a series of valves which dynamically move between a deactuated position and an actuated position. An inlet of the valve system is connected to an outlet of the valve system when all of the valves are actuated and the outlet of the valve system is connected to an exhaust when all of the valves are deactuated. Each valve train includes asolenoid valve which when actuated moves the remaining valve members to their actuated position. The various valves of each valve train are interconnected with the valve of the other valve train such that actuation of all of the valves in a substantially simultaneous manner will connect the inlet of the valve system to the outlet of the valve system and deactuation of all of the valves in a substantially simultaneous manner will connect the outlet to the exhaust. The valve system monitors the dynamic movement of the valve members during its operation will move to a locked out condition when any valve is in a deactuated position and when one other valve is in an actuated position. In the locked out condition, the outlet of the valve system is connected to the exhaust. In one embodiment, The valve system will remain in this locked out condition until a resetting operation is performed. In an additional embodiment, the valve system will automatically reset itself

Abstract: A calibration standard for use with an infrared optical absorption measurement gauge comprises an assembly comprising an optical inter-ference filter (22) and one or more optical elements. The interference filter has spectrally selective properties so that all but a selected spec- tral band is reflected by the filter towards the detectors of the gauge (not shown). The transmitted band is selectively absorbed by the optical el-ement(s) which are spectrally unselective and also directed towards the detectors of the gauge. The position and strength of the selected band can thereby be adjusted to simulate an absorption spectrum, i.e. a corre-sponding spectral band which is characteristic of the absorption spectrum of a material (7) under measurement. The standard is used to calibrate the absorption measurement gauge.

Abstract: An edge clip is disclosed for electrically connecting a conductive pad on the surface of a printed circuit board or its edge to an external connector. The edge clip (10) is substantially U-shaped, with first and second opposing, non-parallel sides (12, 14) defining a space therebetween.      For connection, the printed circuit board edge is fitted into the space such that the opposing sides provide spring-like deflective force against the pad and the printed circuit board (38), thereby providing a more reliable connection. The edge clip may include an alignment feature for facilitating alignment prior to soldering. The alignment feature may include small projections formed on the edge clip to align with, and fit into, holes on the printed circuit board. Scored sections (28) may be disposed on one edge of the clip to facilitate removal of the edge clip from a carrier during assembly. Further, the edge clip may include a center beam (54) extending away from one of the opposing surfaces to provide contact with another metallic surface, such as a miniature card case, thereby providing additional grounding capabilities which can provide protection against static discharge.

Title: A directional hearing system
Inventor: WIDROW BERNARD
IPC: H04R25/00
Filed: 1997-04-17
Granted: 1999-09-21
Abstract: A directional acoustic receiving system is constructed in the form of a necklace including an array of two or more microphones mounted on a housing supported on the chest of a user by a conducting loop encircling the user's neck. Signal processing electronics contained in the same housing receives and combines the microphone signals in such a manner as to provide an amplified output signal which emphasizes sounds of interest arriving in a direction forward of the user. The amplified output signal drives the supporting conducting loop to produce a representative magnetic field. An electroacoustic transducer including a magnetic field pick-up coil for receiving the magnetic field is mounted in or on the user's ear and generates an acoustic signal representative of the sounds of interest. The microphone output signals are weighted (scaled) and combined to achieve desired spatial directivity responses. The weighting coefficients are determined by an optimization process. By bandpass filtering the weighted microphone signals with a set of filters covering the audio frequency range and summing the filtered signals, a receiving microphone array with a small aperture size is caused to have a directivity pattern that is essentially uniform over frequency in two or three dimensions. This method enables the design of highly-directive hearing instruments which are comfortable, inconspicuous, and convenient to use. The invention provides the user with a dramatic improvement in speech perception over existing hearing aid designs, particularly in the presence of background noise and reverberation.
