Abstract: A corner bumper is adapted to be mounted to a corner of a substantially hard-sided carryable case, transport container, or the like, to act as a shock absorber for protecting the case and its contents from exterior impact. The bumper comprises intersecting wall portions to substantially cover the adjacent planes of a corner. The bumper includes feet elements to act as a base upon which the case can stand and space the base a distance from the underlying support surface.

Abstract: A desaturation detector receives signals from a gate driver and circuitry that indicate whether a power semiconductor device is on and in desaturation. A logic circuit produces a signal as a function of the signals, from which a latch circuit produces an output signal. The signal has first and second values respectively in an as-designed condition, and in a short-circuit condition in which the power semiconductor device is on and in desaturation. The output signal has the first value, and transitioned and latched to the second value in response to a transition to the short-circuit condition, which causes the gate driver to switch the power semiconductor device off. And filter(s) reduce noise within the desaturation detector.

Abstract: A method is provided for power limiting in a power inverter configured to produce an output voltage and having a voltage regulator with a voltage setpoint defined for no load on an external bus line. The method includes determining a power level related to a load on the external bus line, determining an adjusted voltage setpoint based on the power level, including: decreasing the voltage setpoint to the adjusted voltage setpoint having a first value when the power level is above a maximum threshold, increasing the voltage setpoint to the adjusted voltage setpoint having a second value when the power level is below a minimum threshold, and slewing the adjusted voltage setpoint to the voltage setpoint so that the adjusted voltage setpoint has a third value when the power level is within a range defined by the maximum threshold and the minimum threshold.

Abstract: A hinge assembly for pivotally joining the opposing halves of a carryable case, especially a case for housing an electronic apparatus. The disclosed hinge is adapted to convey electrical conductors from one half of the case to the other, while protecting them from damage by excessive flexing, abrasion, moisture, and debris.

Abstract: An interposer is shown with contact points on a lateral edge. When assembled between a board under test and an integrated circuit, traces of the interposer carry signals between the board under test and the integrated circuit and also between signal lines of the integrated circuit and the lateral edge contact points. The signals can then be accessed by test equipment at the lateral edge contact points. The interposer may include additional components connected to the traces.

Abstract: Apparatus and methods for generating checksums may process two or more segments of a message in parallel, and may be used with a communications channel having time slots. An apparatus may include a cumulative checksum generator to generate a cumulative checksum for a message, a partial checksum generator to generate one or more partial checksums from one or more respective message segments, and a speculative checksum generator to generate a speculative checksum for each of one or more time slots. In one aspect, a partial checksum corresponding with an initial segment of the message may be generated from at least an initialization vector. A speculative checksum selector may select a first speculative checksum for use in determining whether the message was transmitted without error. The generating of partial and speculative checksums results in a maximally pipe-lined architecture with speed limited only by a minimal cumulative CRC calculation that is fundamentally unavoidable.

Abstract: A method and a control system (20) are provided for determining a relation between stimulation settings for a brain stimulation probe (10) and a corresponding V-field. The brain stimulation probe (10) comprises multiple stimulation electrodes (11). The V-field is an electrical field in brain tissue surrounding the stimulation electrodes (11).

Abstract: A bridge connector assembly may provide access to signals of a circuit that includes an integrated circuit. The bridge connector assembly may include first and second circuit boards that are mated edge to edge, structural members that maintain the position of each circuit board in relation to each other and connectors to carry signals from edge connectors on one board to corresponding connectors on the second board.

Abstract: A test assembly that may provide access to signals of a circuit that includes an integrated circuit. The test assembly may include structural members that limit movement of components relative to each other.

Abstract: A signal analysis system that may include threshold setting for analyzing analog signals. The system may include a plurality of digitizers and adjustable power supplies for supplying threshold voltages for the digitizers. The system may digitize a set of analog signals, locate features and attributes in the digitized signals and determine a duty cycle for signals based on the signal features and attributes. The determined duty cycle may then be used to set threshold voltages on the power supplies.
