    Abstract: A backplane has an array of output terminals arranged on an output surface of the backplane, and an array of solid state optical switches, each optical switch corresponding to one of the output terminals, wherein the solid state optical switches are responsive to light of a control wavelength and are transparent to light of a sensing wavelength, wherein the backplane is of a material transparent to light of a sensing wavelength different from the control wavelength. An optical system includes a backplane having an array of optocouplers, a projector to generate light of a control wavelength to which the optocouplers are responsive, optics to direct the control light onto the array of optocouplers on a backplane, an imaging system responsive to light of a sensing wavelength, wherein the backplane is at least partially transparent to the sensing wavelength.

    Abstract: A microassembler system includes an alignment surface, a two-dimensional array of electrodes adjacent the alignment surface, a sensor network arranged adjacent the array of electrodes, and a control computer electrically connected to the array of electrodes and the sensor network, the control computer to receive signals from the sensor network indicating a position of at least one chiplet and to actuate the electrodes to change the position of the chiplet based upon the signals. A method of assembling chiplets includes receiving, at one of an array of control logic units, a signal from a control computer identifying an assembly location in a block of an assembly template at which a chiplet is to be located, using a sensor to determine a chiplet location of a nearest chiplet, and generating, using electrodes corresponding to the control logic unit, a traveling wave pattern to translate and orient the nearest chiplet to the location.

    Abstract: An elapsed timer device includes a timer element comprising a timer chamber, a timer chamber conditioning material disposed within the timer chamber, and a sensor arranged to sense a timer chemical within the timer chamber. The sensor indicates elapsed time in response to a threshold level of the chemical being present within the timer chamber. The timer chamber, timer chemical adsorption/desorption characteristics of the timer chamber conditioning material, and the sensor are configured so that an amount of the timer chemical within the timer chamber reaches the threshold level within a predetermined time after initialization of the timer element.
