    Abstract: Some embodiments of the technology disclosed herein relate to a sensor device. An elongate sleeve has a first end and a second end and extends along a longitudinal axis. A plurality of sensors are fixed relative to the sleeve. A first endcap is coupled to the first end, where the first endcap has an endcap body. A first axle is coupled to the endcap body, where the first axle extends along the longitudinal axis and the first axle defines a retaining feature. An intermediate component is coupled to the first axle, and the intermediate component is selectively rotatable about the longitudinal axis. The sensor device has an orientation locking structure that is configured to be engaged to selectively fix the orientation of the intermediate component about the longitudinal axis relative to the endcap body.

    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 a lens alignment system having opposing end effectors configured to control a position of a rigid lens body with respect to a plane. In an illustrative example, each of the opposing end effectors may engage a corresponding receptacle on respective opposite faces of the lens body. Each of the end effectors may, for example, frictionally contacts each of the corresponding receptacles within a respective portion of each of at least two contact regions. During the engagement, each of the contact regions may, for example, lie on opposite sides of an axis of rotation that extends between the end effectors. In response to at least a predetermined minimum net moment applied to the lens body, the lens body may, for example, be rotatable about the axis of rotation. Various embodiments may advantageously enable precise and/or rapid positioning of the lens body in the plane.

    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: A sensor device having a sensor housing and a printed circuit board coupled to the sensor housing. A light emitting device is coupled to the printed circuit board. The light emitting device has an emitter face defining an emission face area. An aperture plate is coupled to the sensor housing, the aperture plate defines an aperture having an aperture area that is less than the emission face area of the emitter face. The aperture is less than 1 mm from the emitter face wherein the light emitting device is not fixed to the aperture plate. A lens is coupled to the sensor housing, having an optical axis extending through the aperture. The aperture plate is positioned between the lens and the emitter face. Boresighting angle variation across sensor components on a manufacturing line may advantageously be reduced without increased cost associated with active alignment. Irradiance drop-out may also be reduced.

    Abstract: Apparatus and associated methods relate to a dual-input voltage range compatible light adapted to reconfigure two light elements in series or in parallel and make corresponding current limit adaptations, in response to the input voltage entering one of two predetermined ranges. In an illustrative example, the lighting elements may be strings of LEDs. The current limit may be regulated, for example, by two linear current regulators. In various examples, the current through each of the light elements may be maintained at a predetermined current level independent of the input voltage range. A network of switches may reconfigure current paths among the light elements and the current regulators, for example, in response to the voltage range detected by a control module. The current limit adaptations may advantageously maintain power dissipation of the linear current regulators at a reduced level across a wide input voltage range, and without generating substantial electromagnetic interference.

    Abstract: Apparatus and associated methods relate to a light curtain protection system having a passive optical module arranged to receive, from an active optical module, a light signal such that a reflector reflects, through a polarization control module, the light signal to be received by a receiver in the active optical module. In an illustrative example, the polarization control module includes a half-wave plate aligned with the reflector to impart a first predetermined polarization to the reflected light signal such that the reflected light signal corresponds to a second predetermined polarization when received by the receiver. The polarization control module includes optical elements, such as, for example, a linear polarizer, to receive the reflected light such that the optical elements polarizes the received reflected light signal to correspond to a predetermined polarization. In some examples, the light curtain protection system may advantageously require operating power only for the active optical module.

    Abstract: Apparatus and associated methods relate to dual safety touch button systems for generating machine operation commands, according to predetermined safety guidelines, from status information received via an intercommunications link (ICL) operably connecting the dual safety touch buttons (STBs). In an illustrative example, each of a pair of STBs includes a processor configured to receive, via an intercommunications link port, status information from the other STB. In response to the received information and predetermined safety guidelines, the STBs may generate machine operation commands that operate a pair of relay switches. In some embodiments, each STB may be activated within a substantially simultaneous period (e.g., less than 0.5 seconds) to actuate corresponding relay switches for operating a potentially dangerous machine.

    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.
