摘要： An optical operating element comprises a light-emitting transmitter, an optical receiver, a prism, and a cover. The prism has a side surface that is an active sensor area, and the prism is arranged below the cover such that the active sensor area is oriented substantially parallel to the underside of the cover. The cover has a sensor region which is above the active sensor area and which has a transmittance of at most 99%, at most 95%, at most 90%, at most 80% or at most 50%. Light emitted by the transmitter is guided through the prism and passes through the active sensor area and the cover. The emitted light reflected at an object enters through the sensor region and the active sensor area and is guided through the prism to the receiver. A change in reflection is identified by an evaluation circuit and is interpreted as switching.

摘要： A light receiving detection circuit has a light receiving element configured to receive light emitted from a corresponding projection element, a current/voltage conversion circuit that converts a current signal passing through the light receiving element into a voltage signal, and a filter portion that has a plurality of stages. The filter portion has a high-pass filter and an amplifying circuit. The high-pass filter is able to be switched such that a time constant of the high-pass filter increases when the light receiving element receives light emitted by the corresponding projection element such that the time constant decreases when other projection elements except for the corresponding projection element emit the light.

摘要： An apparatus and method are disclosed to digitize an input electrical signal. A sequence of nonuniformly spaced optical pulses impinges an optical modulator, where the pulses are modulated by the electrical input signal, the optical pulses being detected by one or more photoreceivers, the photoreceiver outputs being electrically sampled in analog-to-digital converters and then processed in a digital signal processor (DSP) in order to measure the electrical input signal. The series of nonuniform pulses are formed by interleaving L uniformly spaced pulse streams each of repetition period T and where fmax, the maximum allowable spectral frequency of the input electrical signal, is greater than 4·L·f/2, where f=1/T.

摘要： A die temperature sensor circuit (200) includes an amplifier (203) that has first and second stages of amplification and that has bipolar transistors (201 and 202) as an input differential pair. The bipolar transistors have different current densities. A difference between base-emitter voltages of the bipolar transistors is proportional to absolute temperature of the bipolar transistors. The bipolar transistors also provide amplification for the first stage of amplification. Multiple feedback loops maintain a same ratio between the current densities of the bipolar transistors over temperature by changing collector currents that bias the bipolar transistors. A feedback loop includes a second stage of amplification and such feedback loop cancels effect that base currents of the bipolar transistors have on an output signal of the die temperature sensor circuit.
