  • Patent number: 11112825
    Abstract: A top case assembly for a portable computer is disclosed. The assembly may include an integral unified (e.g., homogenous) top case formed from a single part. The integral top case provides an enclosure, frame and cosmetic exterior of the portable computer. The integral top case also serves as the primary structure of the portable computer. The assembly may include a variety of subassemblies such as keyboards, touchpads, circuit boards, and drives that are carried by the underside of the integral top case. The integral top case may be formed from aluminum slab that has been machined to form walls, openings, attachment areas and cosmetic areas of the top case.

  • Patent number: 11110493
    Abstract: An electrode film includes a first electrode pattern having a first set of parallel conductive electrodes and a second electrode pattern having a second set of parallel conductive electrodes disposed on a first surface of a transparent film, wherein elements of the first electrode pattern do not cross over elements of the second electrode pattern. A third electrode pattern having a third set of parallel conductive electrodes is disposed on a second surface of the transparent film, wherein the first, second and third sets of parallel conductive electrodes are arranged in an interlaced pattern. The electrode patterns are configured to be connected to respective power sources of electrical power supplying respective waveforms to generate a time-varying electric field pattern above a surface of the electrode film.

  • Patent number: 8600062
    Abstract: Systems and methods are described for over-encrypting symmetrically pre-encrypted content for off-line delivery to playback devices using portable media drives in accordance with embodiments of the invention. One embodiment of the method of the invention includes symmetrically pre-encrypting the content, receiving a request to issue content for playback on at least one playback device associated with a user account, where each playback device includes a processor containing a private key assigned to the playback device by a conditional access system, generating a content key and over-encrypting at least a portion of the symmetrically pre-encrypted content in response to the request, obtaining a public key for each playback device, encrypting a copy of the content key using the public key of each playback device associated with the user account, and delivering the over-encrypted content and the at least one encrypted copy of the content key to a playback device associated with the user account.

  • Publication number: 20080117081
    Abstract: A traffic analyzer for detecting a magnetic permeable mass passing a fixed position includes a calibrated magnetic background memory device, a first magnetic field detector, a second magnetic field detector, a window comparator, and a programmable processor. The first magnetic field detector is operative to detect a change in a magnetic field caused by a magnetic permeable mass passing the magnetic field detector. The window comparator then generates a comparative output of the detected change and a threshold value stored in the calibrated magnetic background memory device. The window comparator then generates a comparative output to place the programmable processor in an active state. The programmable processor is then operative to calculate characteristic data of the magnetic permeable mass using the output from the first and second magnetic field detectors. The characteristic data may be stored in a memory storage device according to a dynamic distribution classification.

  • Patent number: 6388849
    Abstract: An arc fault detector includes an average instantaneous current generator which averages the current over the fundamental period and produces a substantial output only where there are substantial variations in waveform between half-cycles which is indicative of an arc. To discriminate over inrush currents, a pulse generator generates a pulse in response to the step increase in current caused by striking of an arc. An output circuit generates an arc signal when the time attenuated accumulation of pulses occurring in half-cycles in which the average instantaneous current is above a selected threshold reaches a predetemiined level. To further discriminate over dimmers during turn on of a cold tungsten bulb, die ANDing with the average instantaneous current is delayed until a time attenuated accumulation of the pulses reaches a threshold value. The average instantaneous current can be approximated by a bandpass filter with a center frequency below the fundamental of the ac current.

  • Patent number: 5896262
    Abstract: An arc fault detector of the type which generates a trip signal when a time attenuated accumulation of pulses produced each time an arc is struck reaches a selected value, includes a pulse conditioner which discriminates against false trips induced by phenomena such as tungsten bulb burn out and turn on of a cold tungsten bulb controlled by a dimmer. The pulse conditioner includes a zener diode which limits the amplitude of the pulses applied to the integrator, and stretches all of the pulses to reduce the variation in pulse duration. The latter can be accomplished by a peak detector which stretches pulses which reach the zener limit to a duration of at least about a half cycle.

  • Patent number: 5805398
    Abstract: A circuit breaker with an arc fault circuit provides immunity to false trips caused by tungsten bulb burnout and by a cold tungsten filament energized through a solid state dimmer. The detector circuit includes a pulse generator which generates pulses in response to the step increases in current occurring each time an arc is struck. A zener diode limits the amplitude of pulses generated by the pulse generator to a value which is below that of pulses generated by the tungsten lamp. When a time attenuated accumulation of these pulses reaches a predetermined value, the circuit breaker is tripped. By clipping the pulses with the zener diode, the few large pulses generated by tungsten bulb burnout or energization of a cold tungsten bulb by a solid state dimmer switch are insufficient to allow the time attenuated accumulation of pulses to reach the trip value.
