  • Patent number: 6289072
    Abstract: An improved speed indication method for a sensor that develops one or more electrical pulses per unit movement of a movable part, wherein the indicated speed is based on the number of speed pulses generated per unit time, but is constrained by a limit function based on the time elapsed without the generation of a speed pulse. When the pulse generation rate falls below the update rate of the speed indication, a maximum possible speed based on the duration of the “no pulse interval” is computed, and the indicated speed is reduced based on the computed maximum. When the next pulse occurs, the speed indication is updated based on the lower of a new speed calculation and the computed maximum speed. If speed pulses continue to be received, the computed maximum is no longer used as a limit, and the speed indication is updated in accordance with the pulse based speed calculation.

  • Patent number: 6130928
    Abstract: A method of determining the acceleration of a rotating body by counting the number of teeth on a rotating gear member for one or more revolutions. The method minimizes the measurement lag using an overlapping method and calculating acceleration on each control loop that a new revolution count is available. The method determines the new tooth count based on the tooth count estimated for the next update. The old tooth count is discarded and the new tooth count is adjusted to match the old tooth count within the system constraints to provide less interrupts and faster acceleration updates. The number of gear revolutions to be counted are increased at higher gear speeds.

  • Patent number: 5386428
    Abstract: Monolithic arrays having closely spaced laser stripes which output laser beams with large, but well-controlled, wavelength separations. The monolithic array uses a plurality of stacked active regions which are stacked in the order of decreasing energy bandgaps as one moves away from the substrate. Those active regions are separated by one or more thin etch stop layers. Between the bottom active regions and the substrate is a lower cladding layer, while over the topmost active region of each stack is an upper cladding layer. Beneficially, an electrical connection is made to each stack using a heavily doped capping layer/metallic contact above each stack and a metallic contact on the substrate (which is shared by all stacks). Lateral carrier and optical confinement is achieved using a confinement layer which surrounds each stack. Beneficially, that confinement layer is formed using layer induced disordering.

  • Patent number: 4399548
    Abstract: A surge counter for a rotating compressor is provided which detects surging by monitoring the vibration signal from an accelerometer mounted on the shaft bearing of the compressor. The circuit detects a rapid increase in the amplitude envelope of the vibration signal, e.g., 4 dB or greater in less than one second, which is associated with a surge onset and increments a counter. The circuit is rendered non-responsive for a period of about 5 seconds following the detection which corresponds to the duration of the surge condition. This prevents multiple registration of counts during the surge period due to rapid swings in vibration amplitude during the period.
