Research output: Patent


Sensors can be used to obtain encoded sensing results from objects that have nonuniform relative motion. A photosensor or impedance-based sensor, for example, can obtain sensing results from objects that have relative motion within a sensing region relative to the sensor, with the relative motion being, for example, periodically varying, randomly varying, chirp-varying, or modulated relative motion that completes at least one modulation cycle within the sensing region. Relative motion can be caused by varying objects' speed and/or direction or by controlling flow of fluid carrying objects, movement of a channel, movement of a support structure, movement of a sensor, and/or pattern movement. A fluidic implementation can include shaped channel wall parts and/or a displacement component causing time-varying lateral displacement.; A support structure implementation can include a scanner device and a rotary device that respectively control scanning and rotating movement of a movable support structure or of a sensor.
