A probe system includes a probe and a transmission/reception element. The probe and the transmission/reception element are configured such that information is transmittable between them in wireless fashion via a radio signal. The transmission/reception element or the probe has two antennas, set apart from each other, for receiving the radio signal, so that the information received by the two antennas via the radio signal is able to be processed concurrently.

Probe system and method for operating a probe system

A probe system includes a probe head and a transceiver element. Due to contact of a stylus, a sensor signal is able to be generated by a sensor element. The probe head and the transceiver element are configured such that a wireless data transfer is able to be produced between them, so that readiness information is transmittable from the probe head to the transceiver element. The readiness information is transmittable by two bit strings including high bits and low bits, the bit strings being transmittable following defined time intervals, and the second bit string having fewer high bits than the first bit string.

A probe system includes a probe head and a transceiver element. The probe head has a feeler and a sensor element. Moreover, the probe head is able to be transferred from a passive state to an active state, a sensor signal being able to be generated by the sensor element in the active state. The probe head and the transceiver element are configured such that a wireless data transmission is possible between them in a manner that the sensor signal is convertible in the probe head into a switching signal which is transmittable from the probe head to the transceiver element. During the active state, a control command is able to be transmitted continuously in wireless fashion by the transceiver element, the active state of the probe head being able to be maintained by the continuously transmitted control command. Furthermore, the switching signal is able to be transmitted without collision with respect to the transmission of the control command.

A method for serial data transmission between a position measuring system and a processing unit that includes transmitting position data and further data between the position measuring system and the processing unit in serial form as digital data words, transmitting up-to-date position data between the position measuring system and the processing unit upon a position request command and always transmitting further data, whose processing is not time-critical, immediately following the up-to-date position data.

Method and device for serial data transmission between a position measuring system and a processing unit

An optoelectronic transceiver including an optoelectronic transmitting unit disposed along an optical axis and having a radiation-emitting layer region and an active radiation-sensitive layer region. The optoelectronic transceiver further including an optoelectronic receiving unit disposed along the optical axis and is disposed in bridge-like fashion above the optoelectronic transmitting unit. The optoelectronic receiving unit having an active radiation-sensitive layer region disposed perpendicular to the optical axis and located in a thin membrane, which is disposed immediately in front of the radiation-emitting layer region of the optoelectronic transmitting unit, and a radiation-emitting layer region.

Optoelectronic transceiver

A method and a system is for evaluating the transmitted signals of a probe system, which has a probe element that is deflectable out of a rest position and which generates transmitted signals, which include a switch-on signal during a deflection of the probe element out of its rest position and which, together with interference signals, are transmitted to a receiving unit, in which the received signals made up of the transmitted signals and the interference signals, are compared to a reference signal. In this context, the reference signal is formed by interlinking information signals generated from the received signals, and the interference signals, and/or the received signals are differentiated by time, prior to the comparison with the reference signal.
