摘要： An protection barrier provides voltage and current necessarily conveyed to hazardous, such as explosive, areas. The system includes a current sensing circuit which triggers a silicon control rectifier based crowbar circuit in the event over current is detected. This triggering, in turn, trips a relay severing the current path entirely. A reverse polarity circuit provides for immediate clamping of improperly bias connections in a similar crowbar arrangement, and also provides for tripping of the circuit breaker. Thermistors are also provided in current series in the event the circuit breaker fails to trip, or is forcibly bypassed. The circuit breaker additional provides a visual indicator when it is in the tripped position. The intrinsic barrier system is suitable to serving as a first stage protection to zener barrier modules as utilized in the prior art.

摘要： Systems and methods are provided for sensing or measuring capacitive or inductive reactance or changes in reactance in which the sensed reactance is coupled with a known resistance in a sensor circuit and a start signal is provided to the sensor circuit, and a programmable delay line is used to generate a programmable delay signal. The outputs of the programmable delay and the sensor circuits are compared to ascertain which transitions first, and the programmable delay value is adjusted in successive approximation fashion to identify a programmable delay that best represents the delay time of the sensor circuit from which the sensed reactance value can be determined.

摘要： Methods and ultrasonic sensor systems are presented for sensing distance in which an acoustic output signal is directed toward a target and acoustic input signals are received from the direction of the target, and the received signal is compared with a selected one of a plurality of different receiver threshold curves to identify the acoustic wave travel time to the target and back while differentiating between the target and acoustic waves reflected more than once and waves reflecting off obstructions between the sensor and the target, where the user selectable receiver threshold curves are tailored for different target and/or obstruction conditions.

摘要： An assembly for a conveyor system includes a conveyor side rail and a sensor mounting device. The conveyor side rail includes an outer surface, an inner surface, and an opening. The inner surface is the surface generally facing moving components of an associated conveyor system. The sensor mounting device is received in the opening of the conveyor side rail. The sensor mounting device is configured to secure to the conveyor side rail via a resilient fit by an inserting the sensor mounting device into the opening. An associated sensor for the associated conveyor system selectively attaches to the sensor mounting device.

摘要： Low voltage logic circuitry is used to permit an entire subsystem of an industrial controller to be placed within a hazardous environment to receive a high speed serial link and undertake the control of multiple control points without expensive and awkward long cable runs and electrically isolating circuits for each cable run. Energy and bandwidth limiting on the high speed link allows power levels commensurate with high data rates yet intrinsic safety of the media allowing it to freely pass in and out of the hazardous area. A mixture of intrinsically safe and non-intrinsically safe equipment on the same logical rack is allowed through a bus isolator providing isolated data communication in backplane fashion between modules while wholly isolating power transmission along the backplane.

摘要： A palm-button control system provides for machinery control with minimized operator hand pressure by use of capacitive switches and reduced susceptibility to radio frequency interference. The system employs first and second capacitive palm-button switches, both of which must be contacted before machinery is activated. Each capacitive palm-button includes a radio frequency sensor which functions to disable machine activation in the presence of a sufficiently strong radio signal. Circuitry for periodically testing the radio frequency sensors provides periodic visual operator feedback indicative of operability of the system. All controls are synchronized or enabled in accordance with a series of digital pulses.
