Title: Sliding contact mechanical/electrical displacement transducer
Inventor: JACOBSEN STEPHEN C
IPC: G01P15/12
Filed: 1991-02-04
Abstract: ABSTRACT            SLIDING CONTACT MECHANICAL/ELECTRICAL DISPLACEMENT                       TRANSDUCER    Displacement measuring apparatus for measuring the displacement and movement of an object includes an array of sensors having an operative surface and circuitry for producing an electrical output signal whose value is dependent upon the disposition of an electrical/magnetic field producing member along the sensor array.   The field producing member is disposed to contact and slide over  the  operative  surface  as the  object  whose displacement is to be measured is moved.  The value of the electrical output signal produced by the circuitry is  thus  dependent  upon  the  position  of  the  field producing member along the sensor array and thus by the position and movement of the object.

Abstract: ABSTRACT OF THE DISCLOSURE    A webbing for a safety belt comprising warps and wefts is characterized in that the wefts exhibit an elongation of at least 30% at breakage.  Accordingly, the wefts stretch a large amount and with comparative ease when the warps are tensioned or pulled, and therefore the wefts almost never break.  Consequently, the warps also do not break.  The end result is a webbing of increased strength.

Abstract: A periodic pulse discrimination system (10) particularly suitable for use with electronic article surveillance systems is capable of detecting valid tag pulses while discriminating against periodic pulses caused by resonances and interfering carriers as well as random noise. Circuitry that determines the periodicity of a pulse signal and is responsive to amplitude differences between successive detected pulses controls an adaptive threshold and sampling window (30) to discriminate against signals having an incorrect periodicity and an inadequate envelope rise time. A notch circuit (42) notches out pulse trains that have the correct or substantially correct periodicity but persist for a longer time period than the time period required for a tag to pass through the detection zone.

Abstract: A retractable low voltage lighting fixture can be buried in the ground leaving only the top surface exposed and flush with the ground surface. When activated, an interior lamp housing raises out of the ground via a mechanical drive and a lamp contained therein lights up. The lighting fixture provides illumination for walkways, driveways and other areas requiring outdoor lighting. After a specified period of time, the light goes off and the interior housing is driven back down into the ground flush with the ground surface, completely hidden and out of the way of possible damage by vandalism or accidental breakage.  The lighting fixture is comprised of two major component parts - an interior lamp housing and an elongated exterior housing. The interior lamp housing houses the following components: switches, gearbox, motor, electrical components, batteries and light bulb. The exterior housing is buried in the ground and slideably receives the interior lamp housing. The exterior housing provides the appropriate electrical connections and removably receives a gear rack to which the interior lamp housing is drivingly engaged.

Title: Heart assist system with muscle fitness detection by colorimetry
Inventor: GRANDJEAN PIERRE-ANDRE
IPC: A61M60/592
Filed: 1990-12-04
Abstract: Apparatus and method for monitoring the performance of skeletal muscle (22) used in a skeletal muscle powered cardiac assist system. The monitoring is performed by an oxygen sensor (106) which determines the adequacy of circulatory support to the skeletal muscle (22). An adequately supported skeletal muscle can offer the desired cardiac assistance chronically. Insufficient support indicates that the skeletal muscle will easily fatigue until adequate vascularization is achieved. If the circulatory support is chronically insufficient, the risk of ischemia becomes high and additional surgical intervention may be required. A preferred mode employs a two wavelength reflectance oximeter. The sensed data may be stored in memory within an implantable pulse generator. This memory may be interrogated telemetrically.

Abstract: The principal object of the present invention is to provide an effective, easy-to-use and power-driven device for optimizing and comforting the process of using a dental floss to clean teeth. In accordance with this invention, there is provided an automatic dental flossing device comprising an elongate housing handle with an extending thinner arm forked at its front end, in which a pair of removable reels with dental floss on them, a transmission gear system, an operating switch, a winding switch and a powered motor are installed. The handle is divided into three casings which are the upper, bottom and rear casings, respectively. The upper casing is openable for storing or changing the dental floss on the two reels. The gear system is mounted in the bottom casing. The motor is in the rear casing. A pair of guiding slots are grooved on the forked arm which has a pair of slotted conducting tube-like means on its two tines, for guiding the dental floss from the upper casing to the tines of the forked arm. The dental floss, stretched across the two tines of the forked arm, is guided into the handle and wound on the two reels one of which supplies fresh dental floss, another of which takes up the used one. The dental floss can be automatically reciprocated by pulling the operating switch means backward, or tightly held by pushing the same switch means forward. Tension of the dental floss is controllable. On the other hand, the dental floss can be wound continually in one direction, backward or forward, by using the winding switch means. The pair of removable reels carrying the dental floss are driven by the transmission gear system which comprises a primary gear with partially geared circumference, a belt, and two pinions installed on two separate shafts on which the two reels are also installed. The primary gear can be moved into three engaging positions to alternately drive the two pinions, or engage only one of them, so the dental floss will be manipulated in three different operating modes for reciprocating, supplying or rewinding the dental floss. The driving belt deliver power from the motor to the primary gear, having flexibility of slipping on the shafts to release any unexpected overload for protecting the device and user as well.
