Abstract: An apparatus designed to damp external noises, allowing the user to sleep in noisy environments. More particularly, it relates to a pair of hearing-protecting ear covers that insulate the user's ears from external noises, ear covers that incorporate a headphone stereo for transmission of a time, smoke, fire and/or security alarms. The headphone stereo can also transmit music, peaceful sounds, or noise reducing frequencies. The sound producing circuitry is connect in parallel to the alarm system to allow alarm detection even when the user is listening to music or other sounds.

Abstract: A single pull-up circuit is shared between a redundant row antifuse cell, and a redundant column antifuse cell. Additionally, a single selection circuit is shared between the two antifuse cells. A row selection signal supplied thereto selects the antifuse cell for the redundant row, while a column selection signal selects the antifuse cell for the redundant column. A small channel length transistor is employed within the latch circuit. As a result, the latch can quickly pull up a value when the antifuse cell is not blown, and quickly latch that value within the latch since an RC time constant of the latch is decreased. A pulsed pull-up signal having a very short duration is employed to enable the latch. Since the pulsed pull-up signal has a short duration, a high voltage supply V.sub.CC is provided through the latch and a blown antifuse cell to ground for only a short duration, thereby minimizing the possibility of such a low resistance current path from damaging the circuitry.

Abstract: An apparatus for releasably retaining a recreational board, such as a skateboard, snowboard or skis, is shown and described. In one embodiment, the apparatus has a main body with a front portion to which one or more straps is attached, and a rear portion to which a pair of opposing flaps is attached. The flaps extend from the main body such that the second flap overlaps the first flap when the two are wrapped in opposite directions around the recreational board. The overlapping surfaces of the two flaps are secured together to releasably retain the board. A connector is fixed to the second flap and extends from the rear portion of the carrier to the front portion of the carrier where it terminates in a grip. A force exerted on the grip subjects the connector to tension, causes the second flap to be separated from the first flap, and releases the board. In another embodiment, the connector extends through apertures in the front and rear portions of the main body.

Abstract: A telecommunications connector includes a body having a first end to mate with a mating connector and a second end having an aperture. A plurality of connector elements have a connection portion to make electrical contact with individual wires from wire cables. In an exemplary embodiment, the individual wires are in the form of twisted pair cables.

The elongated intermediate portion minimizes the overall surface area of the electrical contacts thereby reducing the capacitance between individual ones of the connector elements. In addition, the connector elements are mounted in a low dielectric constant material to further reduce capacitance between individual ones of the connector elements.

Abstract: A computer system with a memory device having plural memory banks and a method of accessing a selected one of the memory banks, the memory device including local control signal generators that control timing of operations in each respective block of a memory array. Overall timing of the device is controlled by first and second global control signals generated in a command sequencer and decoder. The second global control signal is derived from a delayed version of the first signal, and both signals are applied to local control signal generators along with address bits indicating a selected block. The timing of the global signal generators is determined by row charge and discharge models. Local timing is determined by the global control signals and by local circuitry within the local control signal generators. The second global control signal drives a first portion of a sense amplifier and a delayed version of the second global signal drives a second portion of the sense amplifier.

Abstract: A computer-based method and system for digital 3-dimensional imaging of an object which allows for viewing images of the object from arbitrary vantage points. The system, referred to as the Lumigraph system, collects a complete appearance of either a synthetic or real object (or a scene), stores a representation of the appearance, and uses the representation to render images of the object from any vantage point. The appearance of an object is a collection of light rays that emanate from the object in all directions. The system stores the representation of the appearance as a set of coefficients of a 4-dimensional function, referred to as the Lumigraph function. From the Lumigraph function with these coefficients, the Lumigraph system can generate 2-dimensional images of the object from any vantage point. The Lumigraph system generates an image by evaluating the Lumigraph function to identify the intensity values of light rays that would emanate from the object to form the image.
