Abstract: A tray handler for transporting a tray into or out from a selectable position within a tray stack stowed in the tray handler has an unload station to stow a tray during a sort procedure, a tray elevator configured to vertically transport the tray stack to the selectable position such that the tray is positioned to be horizontally received from or by the unload station, and a separator above the tray elevator and coupled to the unload station, the separator configured to vertically split the tray stack for opening the selectable position and horizontally transporting the tray into or out from the unload station.

Abstract: Asynchronous electrical circuitry produces a stationary carrier signal and encodes a system input signal amplitude into output signal time-sequence information by establishing at a digitizer an operating point value as an average amplitude of the system input signal. It applies to the digitizer a multicomponent digitizer-input signal corresponding to a sum of a passband signal component and a feedback signal component to produce a pulse-width modulated digitizer output signal representing the system input signal. An asynchronous time delay is introduced to produce the pulse-width modulated system output signal. The circuitry performs digital-to-analog conversion (DAC) to the pulse-width modulated system output signal to produce a DAC output signal. The DAC output signal or its summation with the passband signal component is integrated to produce the feedback signal component. Additional, multiple-order embodiments include sequential feedback paths or carrier-shaping functions.

Abstract: Asynchronous electrical circuitry (400, 500, 600, 700, 800, 900) produces a stationary carrier signal (470, 470?) and encodes a system input signal (460, 460?) amplitude into output signal time-sequence information by establishing at a digitizer (410, 510, 610, 710, 810, 910) an operating point value (416, 516, 616, 716, 816, 916) as an average amplitude of the system input signal. It applies to the digitizer a multicomponent digitizer-input signal (470, 470?) corresponding to a sum of a passband signal component and a feedback signal component to produce a pulse-width modulated digitizer output signal (480, 480?) representing the system input signal. An asynchronous time delay (t(s)) is introduced to produce the pulse-width modulated system output signal (y(s)). The circuitry performs digital to analog conversion (DAC) to the pulse-width modulated system output signal to produce a DAC output signal (490, 490?).

Abstract: In one embodiment, a power conversion system includes a controller to provide power control to a converter, and a distortion mitigation circuit. In another embodiment, a system includes a converter to transfer power between a power source and a load having fluctuating power demand, and a controller to provide power control, where the controller may selectively disable the power control. In another embodiment, a power conversion system includes a controller to generate a drive signal to provide power control to a power path in response to a sense signal from the power path, where the sense signal is taken from other than the input of the power path, or the drive signal is applied to the power path at other than a first power stage.
