Abstract: A method of obtaining a dot product using a memristive dot product engine with a nulling amplifier includes applying a number of programming voltages to a number of row lines within a memristive crossbar array to change the resistance values of a corresponding number of memristors located at intersections between the row lines and a number of column lines. The method also includes applying a number of reference voltages to the number of the row lines and applying a number of operating voltages to the number of the row lines. The operating voltages represent a corresponding number of vector values. The method also includes determining an array output based on a reference output and an operating output collected from the number of column lines.

Abstract: A color analysis system includes a light source and a sensor configured to provide an output signal in response to reflected light received from the first light source. A controller receives the output signal and is configured to determine an adjustment factor based on the output signal, and determine a color based on the output signal and the adjustment factor.

Abstract: A color analysis system includes a plurality of light sources configured to illuminate a test patch. A sensor is configured to receive light from the plurality of light sources reflected from the test patch. A controller is configured to determine the color of the test patch in response to light received by the sensor reflected from the first light source, and adjust the color determination in response to light received by the sensor reflected from the first and second light sources.

Abstract: A computer implemented method for utilizing a plurality of self-activating display shaping devices to provide shape adjustment information for a digital image projected on a display is disclosed. In one embodiment, the plurality of display shaping devices are automatically activated, the plurality of display shaping devices defining a desired digital image shape for a display. In addition, the plurality of display shaping devices is utilized to identify an actual projected digital image shape. The actual projected digital image shape is then compared with the desired digital image shape for the display. Correction information is then provided for adjusting the actual projected digital image shape to approximate the desired digital image shape for the display.

Abstract: A device includes a housing; a color sensor within a first end of the housing, the color sensor configured to sense a color of a sample when the color sensor is placed proximate the sample; and a display within the housing, the display configured to display the color of the sample sensed by the color sensor.
