摘要： The present invention is a vehicle traffic measurement system designed to accurately count and record the number of vehicles passing through a selected location, to more accurately determine and record the velocity at which the individual vehicles travel through that location, and to accurately determine and record in which relative direction the vehicles are traveling as they pass that location. The basic physical principle is of a moving object interrupting two parallel light beams a known reference distance apart, and information extracted from the interruptions sensed and electronically processed into count, direction, and velocity being recorded for subsequent data analysis.

摘要： A method for recognizing potential faults of one or more remote body detectors of a door can be applied to a wide variety of conventional detectors that may not necessarily have a self-monitoring feature themselves. The method may be counter-based, timer-based or a combination of the two. In some embodiments, the method involves comparing the behavior of a detector to that of another detector at the door or to the activity of another door-related event, such as the door opening or closing. In some cases, the activity of a single detector is compared to a predetermined acceptable range of activity over a given period.

摘要： A level of received light detected by a light-receiving means (R) is given to both an indication controller (11) and a transmitter (13). The indication controller (11) obtains a flashing frequency corresponding to the given received light level, and flashes an LED (12) at the frequency obtained. The received light level transmitted from a transmitter (13) is demodulated and decoded in a receiver (4) and then given to an indication controller (3). The indication controller (3) obtains a flashing frequency corresponding to the given received light level, and flashes an LED (2) at the frequency obtained. Thus, the operator can recognize the received light level readily and reliably. Accordingly, it is only necessary for the operator to adjust the angle of the projecting optical system of a light-projecting means (T) in the vertical and horizontal directions so that the flashing frequency of the LED (2) lowers and eventually the LED (2) turns off, and to adjust the angle of the receiving optical system of a light-receiving means (R) in the vertical and horizontal directions so that the flashing frequency of the LED (12) lowers and eventually the LED (12) turns off.

摘要： An electromagnetic (EM) radiant energy beam source transmits a beam of reflectable EM energy toward the space in a hospital bed normally occupied by a patient being monitored. In one embodiment, the beam is reflected by the patient if found within the confines of the hospital bed, and the reflected beam is detected by an EM energy sensor located on the apparatus. A control logic circuit then receives data from the energy sensor regarding the level of reflected energy detected. If a certain beam intensity level has been detected, the control logic circuit sends a signal to an output relay that the patient is still in the bed. If the patient is no longer in the bed, an alternate signal is sent to the output relay. The output relay serves as an interface to an external occupancy monitoring system or may alternatively operate an alarm bell or light to indicate the absence of the patient.

摘要： Pulse formers (14) driving respective LEDs (12) are energized by the cells of a shift register (16) which is docked by a clock line (CK), and to whose first cell an initial pulse is applied by a first signal generator (GR). A barrier-end Line (FB) is connected to the output of the shift register and to the input of the first signal generator. The latter resets the shift register cells through a reset line (RS). A plurality of photodiodes (42) facing the LEDs are connected in common to a bus line (BUS) through resistors (47) and electronic switches (44) which are dosed in turn by the cells of a shift register (46) similarly controlled by a second signal generator (GE) in synchronism with the first. The bus line is connected across a voltage supply through resistors (61, 63) and provides a multi-level signal to an evaluator circuit (VAL). The two shift registers, including the associated LEDs or photodiodes, may form blocks connected in cascade.

摘要： A light curtain system and method of operation includes a control circuit having visible light indicators positioned adjacent channels of individual light beams established across a guard zone. The light beams are transmitted along a plurality of parallel channels between a transmitter bar and receive bar. The control circuit operates to sense when one or more beams are blocked by the intrusion of an opaque object. The circuit responds by operating visible light LEDs which are positioned adjacent the channels of the blocked beams. The visible light provides continuous feedback to the machine operator as to the condition of the guard zone. The visible light indicators are also used to facilitate alignment of the transmitter and receiver bars.

摘要： A photodetection system and related circuitry designed to sense the intrusion of an opaque object in a light plane. Upon sensing the intrusion, the system quickly initiates a machine-stopping sequence prior to the opaque object coming into contact with the machine while that machine is operating. The system comprises a SYSTEM microcontroller and a WATCHDOG microcontroller, both of which operate an output control device of the light curtain switch of the invention, wherein the output control device comprises a plurality of electromechanical relays. Both microcontrollers also perform system hardware and software integrity checks. Furthermore, the WATCHDOG microcontroller evaluates the performance of the SYSTEM microcontroller by transmitting a false intrusion signal to a photosource, determining whether the false signal has been detected, and then verifying that the SYSTEM microcontroller has initiated the machine-stopping sequence. The machine-stopping sequence may be overridden by the WATCHDOG microcontroller, or it may be initiated if the false signal is not detected. The combination of electronic, mechanical, and optical modules of the present invention provides improved reliability and accuracy. In addition, the SYSTEM microcontroller and the WATCHDOG microcontroller are designed so as to reduce the system's sensitivity to spurious signals.

摘要： A photoelectrical switching circuit, which produces a pulse-modulated light for detecting presence of an object by light interruption or reflection, comprises a frequency divider circuit and a signal output circuit and may comprise a control circuit. The frequency divider circuit includes a counter formed by flip-flops and an operation stop circuit. The counter generates light emission pulse signals with variable period and read pulse signals to pick up light sensing signals and outputting the state of the final stage flip-flop as an operation signal. The operation stop circuit stops the operation of the final stage flip-flop after the operation signal is input. The signal output circuit, which provides output signals after the operation signal is input, includes a shift register for shifting the light sensing signals in step with clock pulses, a set output AND circuit, and a reset output AND circuit. The output AND circuit provides a logical product of a set output of the final stage and a set output of the m-th stage of the shift register to direct set terminals of the m+1-th and subsequent stages of the shift register, the reset output AND circuit performs the same operation with the reset outputs and the reset terminals of the shift register, and then the signal output circuit outputs output signals of the final stage of the shift register. The control circuit makes the period of pulse signals of the frequency divider circuit fixed for a predetermined length of time.
