Abstract: A plurality of video cameras (7a-d) are mounted on a table which is adapted support a workpiece or other object to be measured, and the mounting of each camera to the table provides for controlled universal orientation of each camera via an articulating head having provision for selective rotation about each of two orthogonally related axes. The table is provided with vibration damping, whereby both the measured object, and the cameras which provide triangulation data for each measurement, can operate from the same rigid base, isolated from external sources of mechanical shock. The video signals of the cameras are fed, along with instantaneous optical-axis orientation data for each camera, to the computer of a coordinate-measuring machine.

Abstract: A reflectance oximeter is so mounted to the upstream or proximal side of a laryngeal mask as to face the posterior wall of the pharynx when the laryngeal mask has been positioned to perform its function of sealed, exclusive airway communication with the laryngeal inlet. Thus positioned, radiation from the oximeter can utilize local back-bone features as a reflector, for two-way passage of the radiation through tissue which characterizes the posterior wall of the pharynx. Moreover, the oximeter-observation region is within the body, so that ambient light has no degrading effect, and changes in oxygen saturation will be detected earlier than by use of any peripherally placed oximeter probe.

Abstract: Coins stored in a hopper (1) are delivered one by one towards an outlet of a hollow cylindrical case (3) on a base plate (2) by coin feeding arms (9) of a coin feeding disc (4) having coin receiving holes (8). The coin feeding disc (4) is rotated in the hollow cylindrical case (3). The coin is further delivered out of the hollow cylindrical case (3) by coin feeding wings (12) of a scraper (13) rotated on the base plate (2) outside of the hollow cylindrical case (3). An upright coin carrier duct (17) is disposed, with an opening at the lower end thereof, on the inclined base plate (2). A coin guide (21) is disposed along a coin transporting path (15) where a coin is delivered by the coin feeding wings (12) of the scraper (13). The coin engaged with the coin guide (21) is pushed towards the lower end port of the coin carrier duct (17 ) by a convex portion formed at the leading side of each of the coin feeding wings (12).

Abstract: A jig is detachably secured to the proximal end of an installed intramedullary nail having a transverse bolt hole near the distal end of the nail. The jig comprises an offsetting arm which so mounts an elongate template as to be movable in a geometric plane substantially parallel to the nail. A guide bore near the distal end of the template is on an axis perpendicular to the geometric plane. When the jig is chucked to the nail, the axis of the guide bore of the template is parallel to the axis of the bolt hole of the nail, and both the guide-bore axis and the bolt-hole axis are at identical distance from the offsetting arm. The distal end of the template is adapted to removably mount a metal-detector establishing a magnetic-field about a directional axis, such that the metal-detector can be selectively moved or positioned on one and then the other side of a central position in which the template is strictly parallel to the nail.

Stock trade executions, quotations and other ticker plant information is communicated in parallel to a hierarchy of system data processing terminals, e.g., those located at area, branch and individual work station locations. Storage media at the several system data processing levels extracts and stores data base information of differing purport and completeness for the disseminated data to support the system work station users.In accordance with one aspect of the present invention, information characterizing a dynamically changing sub-population of the overall ensemble of market securities is maintained at and becomes immediately available to each work station responsive to the pattern of usage at that specific station.

Abstract: An elongate bandage that is predominantly stretchable in the longitudinal direction enables readily applied development of an elastic surgical limb sleeve that can be rendered locally inextensible. The bandage features multiple longitudinally spaced rows of transverse slits which are in staggered offsetting interlace, from one to the next-adjacent row, such that when a circumferential wrap of the bandage completes a sleeve, the multiple slits are arrayed parallel to the axis of the limb. The limb sleeve gently conforms to the shape of an affected or injured joint or other body part, and the gentle conformance is operative to convert slits into ventilation openings. One or more strips of relatively inelastic hook material applied to the outer surface of a developed sleeve not only complete the sleeve but, when desired by the surgeon, can exert localized pressure to the injured area either directly or indirectly as in the treatment of swelling or in the control of bleeding.

Abstract: An oral hygiene composition in a suitably applicable form for whitening and cleaning teeth provides a non aqueous composition containing an oxygen releaser such as calcium peroxide, magnesium peroxide or potassium chlorate. The oxygen in these agents is stable in the composition until the composition meets water during actual brushing at which time the oxygen is released to effect a bleaching action removing stains from the surface of the teeth, thereby serving to whiten them. The composition may be formed with other known dental hygiene constituents providing for whitening and hygiene in one application.

Abstract: A system for delivering audio advertising messages to shopping carts moving through a plurality of spatially defined transmission zones arranged in the aisles of a store. In the illustrative embodiment, a plurality of transmitters of compact construction are each attached to a shelf within the store. Each shelf transmitter has a spatially defined transmission zone of selected geometry and predetermined dimensions so as to occupy an assigned region of space within one of the aisles in the store. When any one of these transmitters detects a shopping cart residing in its spatially defined transmission zone, the transmitter transmits over its spatially defined transmission zone, a modulated signal carrying an audio message provided by a playback mechanism within the transmitter. A receiver on the detected shopping cart demodulates the received modulated carrier signal and produces an audible signal of the audio message provided by the playback mechanism in the transmitter.

Abstract: The present invention provides a method and apparatus for prepayment of telecommunication connections between first and second telecommunication devices operably associatable with the telecommunication lines of a telecommunication switching network. In general, the method involves storing telecommunication-time data representative of a prepurchased amount of telecommunication-time available for payment of telecommunication connections in the telecommunication switching network. At the initiation of the first telecommunication device, a telecommunication connection is established between the first and second telecommunication devices so that a telecommunication process can be conducted therebetween. The telecommunication connection between the first and second telecommunication devices is terminated in response to termination of the telecommunication process. The time duration of the telecommunication connection is measured.
