Filed:

Aug 22, 2001

Appl. No.:

09/935374

Inventors:

Asad M. Madni - Los Angeles CA
Jim B. Vuong - Northridge CA
Robert K. Hansen - Burbank CA

Assignee:

BEI Sensors Systems Company, Inc. - Sylmar CA

International Classification:

G01L 312

US Classification:

73862326, 32420717

Abstract:

A non contacting angular differential displacement torque sensor utilizes a split shaft with a connecting torsion bar with a pair of receive disks each with an intervening coupler disk carrying a conductive attenuating pattern where the inductive coupling between transmit and receive disks is individually attenuated in accordance with the angular position of the shaft on which the disks are mounted. The pair of receive disks which receive signals from a common transmitter have their angular difference taken and this is the actual torque on the shaft.

International Classification:

G01L 314

US Classification:

73862337

Abstract:

A differential capacitive torque sensor for a continuously rotating shaft such as the steering column of an automobile provides an apertured metal cage shielding a dielectric rotor. They are respectively mounted on opposite sides of a split shaft connected by a torsion bar. The relative rotation of the apertured conductive plates and the rotor change the overall differential capacitance of the system to proportionally indicate clockwise or counter-clockwise torque.

International Classification:

G01L003/14

US Classification:

73862337, 73862045, 73862325, 310 40 R

Abstract:

A radial movement capacitive torque sensor includes a pair of concentric capacitor plate rings lying in a common plane, a capacitor plate ring facing the pair of concentric capacitor plate rings, and a paddle assembly disposed between the pair of concentric capacitor plate rings and the capacitor plate ring. The paddle assembly includes a first rotor having a circular opening and having at least one pair of spaced apart bearings mounted thereon, a second rotor having a circular opening and having at least one pivot point located thereon, and at least one paddle having a dielectric head, a curved neck and a body. The curved neck is disposed between a corresponding one of said at least one pair of spaced bearings, and the body is pivotally coupled to a corresponding one of said at least one pivot point. The sensor can be mounted on a shaft having two shaft portions interconnected by an embedded torsion rod to measure the torque applied to the torsion rod when the shaft portions are rotated one with respect to the other.

US Classification:

324658, 381400

Abstract:

A voice coil actuator having a capacitive sensor. A magnetic housing contains at least one magnet, and has a wall that defines a first cavity. A magnetic core is coupled to the magnetic housing and extend from an interior surface of the magnetic housing in a direction of a center axis of the wall of the magnetic housing. A coil assembly has a wall defining a second cavity that at least partly envelops the magnetic core, disposed at least partly inside the first cavity, and adapted to move linearly with respect to the magnetic housing. The coil assembly forms a capacitive sensor with the magnetic core, the capacitive sensor adapted to measure at least one of position, velocity and acceleration of the coil assembly with respect to the magnetic housing.

International Classification:

A61B 104

US Classification:

600115

Abstract:

An endoscope which is both flexible and easily cleaned having a pair of telescoping sections at its distal end one of which carries a camera and which are alternately actuated to provide movement through a body passageway by a Bowden type of cable. Such cable has an outer helical casing with an inner steel wire. Respectively attached to the two cylindrical sections are inflatable bladders which provide for the movement above which also are an integral part of the flexible sterilized sheath being held to the respective sections by O-rings.

International Classification:

H04M 1100

US Classification:

179 2A

Abstract:

A number of remotely located locked devices (26 and 27) are selectively operated by sending signals from a central supervisory location (28) through the telephone network (27) to a telephone set 32 and a converter (44) installed at each remote location. Initiating call signals from a remote telephone set are automatically generated and routed through the telephone network to a supervisory telephone set equipped with a standard 0-9 digit dial plus a special pushbutton (34) for generating a special signal. Receipt of the special signal at a calling remote station disconnects the remote telephone set and conditions a stepping circuit (74-86) and a sequence circuit (81-82) for subsequent operation upon receipt (88-104) of a predetermined sequence of 0-9 digit signals. Upon receipt of the predetermined sequence of signals within a first set time period, the stepping circuits and the sequence circuits are operated to generate (111) a signal that releases the locked device for a second set time period.
