    Abstract: Apparatus and associated methods relate to a modular plug-in accessory including a connector for making pluggable electrical connection to a cascading electrical output port for providing cascading connection from an elongate light curtain, the accessory comprising an omni-directional light indicator to illuminate a light signal indicative of a status of the light curtain, wherein the accessory is configured to releasably make or break operative connection to the end cap containing the output port while the end cap is sealably connected to an end of the light curtain. In an illustrative example, the accessory may plug in directly to the terminal end of a light curtain. The receiving light curtain may be connected at the distal end of a string of light curtains. In some examples, the accessory may provide high visibility status indication information about any of the light curtain segments in the string of light curtains.

    Abstract: Apparatus and associated methods relate to a stretchable cover assembly (100, 600, 1000, 1200) permeable to electromagnetic signals formed within an enclosed device envelope to increase the resilience of the actuator body envelope against high-pressure fluid. In an illustrative example, a cover assembly is configured to encapsulate an electronic device (101, 1000, 1200). For example, the cover assembly may include a unitary envelope formed from a translucent, radio permissive, and ultraviolet light reflective material. An internal cavity defined by the unitary envelope may repeatedly receive substantially an entire exposed surface of the electronic device. The cover assembly may include an elastic opening that, in a relaxed state, the elastic opening is configured to be sealingly pressed against the enclosed electronic device forming a seal around the entire elastic opening to form a dust-tight and watertight cover. Various embodiments may advantageously protect the enclosed electronic device while selectively permitting electromagnetic signals to pass through.

    Abstract: Apparatus and associated methods relate to an alignment system including an alignment source module (ASM) and an alignment indicator module (AIM) configured to be releasably coupled to a first unit and a second unit, respectively, of a pair of optoelectronic arrays. In an illustrative example, the ASM may be oriented, when coupled, to emit an optical beam in substantial alignment with a first optical axis of the first unit. The AIM may, for example, be configured, when coupled, to provide a visible indication when the optical beam is within a predetermined near-alignment orientation range relative to a second optical axis of the second unit. Each of the AIM and the ASM may, for example, be configured to axially couple along respective longitudinal axes of the first unit and the second. Various embodiments may advantageously facilitate manipulation of the pair of optoelectronic arrays into near alignment with each other.

    Abstract: Apparatus and associated methods relate to a field-adjustable distance sensor configured to translate a transfer function of the sensor by a substantially constant value in a position domain by calibration at one or more known distances. In an illustrative example, the transfer function may correlate multiple distances to corresponding position vectors describing a position of a light signal on a receiver. The receiver may, for example, generate a detection signal corresponding to a position on the receiver of a light signal reflected off a target. A control circuit may, for example, generate a position vector in response to the detection signal. A calibration constant (C) may be generated, for example, as a function of a known distance of the target and position vector. C may be applied, for example, to translate the transfer function in the position domain. Various embodiments may advantageously reduce non-linear error in a distance sensor.

    Abstract: Apparatus and associated methods relate to a select frequency phase measurement (SFPM) time of flight (TOF) system including an emitter and a receiver. The emitter may generate a modulated emitted signal by at least one frequency. The emitted signal may, for example, be a pulsed light signal. The receiver may generate a signal in response to receiving a reflection of the emitted signal off a target object. An ADC element may digitize a signal generated by the receiving element, and a reference signal generated by a monitored signal of the modulated emitted signal. A processing element may generate a phase signal using single frequency analysis of the digitized signals. A distance measurement signal may be generated as a function of the phase signal. Various embodiments may, for example, advantageously enable sub- millisecond sensor response times using commodity processing elements.

    Abstract: Apparatus and associated methods relate to detection systems with chatter-mitigated output indication. In an illustrative example, a sensor may generate a detection signal as a function of a physical relationship of a target to the sensor. A control circuit may, for example, generate a control signal in response to the detection signal and as a function of a predetermined indication response profile defining a transition threshold for each of multiple nominal transition points. A light-emitting indicator array may, for example, generate spatially distributed indication in response to the control signal. The indication may, for example, change from a first spatial distribution to a second spatial distribution in response to the detection signal crossing a first nominal transition point by at least a corresponding transition threshold (δ1i). Various embodiments may, for example, advantageously prevent the visual indication from responding to perturbations in the detection signal.

    Abstract: Apparatus and associated methods relate to a side-mounted field-installable indication module (SMFIIM) configured to reflect a status of a manufacturing area (e.g., a status a machine, status a light curtain). In an illustrative example, the SMFIIM may include a light emitting module configured to emit a visual indicium corresponding to the status of the manufacturing area, and a coupling member configured to be releasably captured within a longitudinally extending channel of a housing of a light curtain. After installation, for example, the SMFIIM may be disposed on a side of and substantially parallel to the housing. The light emitting module may emit the visual indicium in an emitting plane oriented at an angle less than 90° to a plane tangential to a mounting surface of the light curtain housing. Various embodiments may advantageously provide a wide viewing angle of the light emitting module around the lighting curtain.

    Abstract: Apparatus and associated methods relate to detecting jams when an intensity of a reflected signal exceeds a predetermined intensity threshold and an intensity window metric based on historic intensity value(s) fails to exceed an intensity window threshold for more than a predetermined time threshold. In an illustrative example, a jam detection unit (JDU) may emit a signal and detect a reflection of the signal. The JDU may, for example, compare intensity of the reflected signal to the intensity threshold. The JDU, for example, may compare the intensity threshold with at least one historic intensity value to determine the intensity window metric. If the intensity value exceeds the intensity threshold and the intensity window metric has not exceeded the intensity window threshold for longer than the time threshold, then the JDU may, for example, generate a jam signal. Various embodiments may advantageously detect jams based on intensity of a reflected signal.

    Abstract: Apparatus and associated methods relate to generating a wiring schema with more than one safety device sharing at least one test signal through one or more external terminal blocks when the number of terminals required by safety devices exceeds the number of available terminals of a safety controller. In an illustrative example, the method may include determining a total number of terminals A of safety devices to be connected to a safety evaluation device having a number of terminals B. If A is greater than B, the method may then include generating a wiring schema that one or more external terminal blocks may show indicia of electrical connections between an identified set of safety devices and a shared terminal of the safety evaluation device associated with that set. By using the method, the number of devices that can be connected to the safety evaluation device may be expanded.
