A laser processing system includes: a first light irradiator including: a first light emitter to emit first laser light; and a first light scanner to scan a first region of a workpiece with the first laser light emitted from the first light emitter; a second light irradiator including: a second light emitter to emit second laser light; and a second light scanner to scan a second region different from the first region of the workpiece with the second laser light emitted from the second light emitter. The first light irradiator emits the first laser light to the first region of the workpiece in a first irradiation direction, the second light irradiator emits the second laser light to the second region of the workpiece in a second irradiation direction opposite to the first irradiation direction.

A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGO™ RFID backscatter transponders, SEGO™ RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.

A vehicular system (1) detects a magnetic marker (10) laid in a road and wirelessly communicates with a wireless tag (15) attached to the magnetic marker (10). The system includes a measuring unit (2) which detects the magnetic marker (10) by sensing magnetism, a tag reader (34) which executes a communication process with the wireless tag (15), and a control unit (32) which sets a communication start point as a start point of the communication process by the tag reader (34). The control unit (32) sets, as a communication start point, a time after a lapse of specified time with reference to a time point of detection at which the measuring unit (2) detects the magnetic marker (10). Upon reading information from the wireless tag (15), the tag reader (34) terminates communication, thereby shortening a communication time.

Approaches for synchronising electronic animal identification tag readers for reading electronic animal identification tags attached to animals Embodiments include using a pulse from a GNSS receiver, adjusting for an error between a reference cadence signal and a local cadence signal, and using a synchronisation signal.

A reading apparatus includes a synchronizing signal output unit, a first imaging unit, a second imaging unit, an acquisition unit, and a transmission unit. The synchronizing signal output unit outputs a synchronizing signal. The first imaging unit images a read target at an imaging position from a first direction in synchronism with the synchronizing signal. The second imaging unit images the read target at the imaging position from a second direction in synchronism with the synchronizing signal. The acquisition unit acquires a first image of the read target captured by the first imaging unit in synchronism with the synchronizing signal, and a second image of the read target captured by the second imaging unit in synchronism with the synchronizing signal. The transmission unit correlates the first image and the second image, and transmits the correlated first image and second image.
