Patent ID: 8153950

Claim:
Apparatus comprising: an encoder/sensor that obtains sensing results from objects in an encoding/sensing region relative to the encoder/sensor; a trigger detector that responds to each of a set of distinguishable objects when the object is in a trigger detection region relative to the trigger detector, providing a respective trigger signal; a relative motion component that causes relative motion of a subset of the distinguishable objects into the trigger detection region, from the trigger detection region into the encoding/sensing region, and within the encoding/sensing region; and a circuitry component that includes at least one of: control circuitry that, in response to the respective trigger signal of an object in the subset, provides control signals that cause one or both of the encoder/sensor and the relative motion component to operate so that the encoder/sensor obtains respective encoded sensing results indicating at least one time-varying waveform with information resulting from the object's relative motion within the encoding/sensing region; and processing circuitry that, in response to the respective trigger signal of an object in the subset, obtains data from the sensing results, the data indicating at least one time-varying waveform with information resulting from the object's relative motion within the encoding/sensing region.
