摘要： A calibration device is provided for use with automatic test equipment (ATE). The calibration device includes circuitry having a fanout circuit. The compare-side fanout circuit has an input connected to a first channel of the ATE and outputs connected to N (N>1) channels of the ATE, where the N channels do not include the first channel. The ATE propagates an edge on the first channel, and the fanout circuit transmits the edge to the N channels. Optionally, a calibration device for use with automatic test equipment includes a drive-side circuit. The drive-side circuit includes circuitry having multiple inputs connected to N (N>1) channels of the ATE and an output connected to a second channel of the ATE that is not one of the N channels. The ATE propagates an edge on each of the N-channels and the circuitry propagates each edge to the second channel of the ATE.

摘要： A trackpad has a cover abutting a housing. The cover includes a body that is transparent to infrared light and visible light. A first ink, deposited in a first area on a surface of the cover body, is transmissive to the infrared light and substantially opaque to visible light. A second ink is deposited in at least one second area on the surface of the cover body and is transmissive to visible light. A first emitter, within the housing, produces infrared light that is transmitted through the cover. A second emitter, within the housing, produces visible light that is transmitted through each second area of the cover. An optical sensor is provided within the housing for receiving infrared light that is reflected by an external object back through the cover.
