Granted: 1999-08-31
Abstract: A surround sound processor for presenting stereophonic audio signals on a number of loudspeakers surrounding a listening area, comprising an input matrix stage, a detector filter and matrix circuit, a direction detector circuit incorporating improved filters, a novel detector splitter circuit providing three direction signals from the two direction detector circuit outputs, a novel three-channel servologic circuit with improved variable filters responding selectively to the rates of change of the direction signals and providing six control voltage signals through linearity correction networks to six voltage-controlled amplifiers, the outputs of which are combined in an output matrix to provide a number of loudspeaker feed signals through buffer amplifiers to the output terminals of the processor. The detector splitter circuit is configurable to either a forward oriented or a backward oriented mode of operation, corresponding changes being made to the voltage-controlled amplifiers and output matrix circuitry.  Additionally the detector splitter may be switched to eliminate the third direction signal with corresponding changes to the output matrix circuitry.

Abstract: The present invention discloses a spinal fusion implant that is at least partially cylindrical, made of material appropriate for human implantation and having preferably, but not necessarily, one closed end and one end capable of being closed, such that an internal chamber can be filled and hold any natural or artificial osteoconductive, osteoinductive, osteogenic, or other fusion enhancing material. The partially cylindrical implant directly participates and is incorporated in the ensuing fusion. In the preferred embodiment, the implant of the present invention relies on surface roughenings of the outer surface to enhance its stability and resist dislodgement from within the disc space between two adjacent vertebrae. The implant of the present invention incorporates at its rear end, an engagement means to facilitate insertion or extraction of the implant. The implant may be filled with, coated with, and/or composed of, fusion promoting substances. Finally, the implant of the present invention does not require rotation for its insertion and can be seated by linear advancement.

Abstract: A brake control apparatus for a vehicle employs a pressure-amplifying device which reduces a quantity of brake fluid generating a  first brake-fluid pressure in a  first conduit connected to a master cylinder, and increases second brake-fluid pressure in a second conduit, applied to a wheel cylinder  simultaneously with the  reduction in brake-fluid quantity in the first conduit. As a result, increase in the first brake-fluid pressure is suppressed even when a driver depress  a  brake  pedal  and  load  to  generate  the  first brake-fluid  pressure  is  alleviated.    Additionally,  the pressure-amplifying  device  applies  the  increased  second brake-fluid pressure to the wheel cylinder.  Therefore, it is possible to ensure sufficient braking force.

Abstract: A lightweight braided metallic shielding is applied to wiring harnesses to protect against lightning strikes and electromagnetic interference (EMI). The braided shielding has an open braid construction which may be as much as 40% lighter in weight and which provides better electromagnetic shielding th an conventional braided shielding. The decrease in weight is achieved by utilizing a braid carrier application angle, as measured from the axis of the wire harness, which is as small as about eighteen degrees, so as to produce a braided shie ld that has as few as four picks per inch. The ensuing braided shield is very flexib le and results in a degree of wire harness coverage which may be as low as about 60 %, but which exhibits low electrical resistance which contributes significantly to lightning protection and EMI shielding.
