    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: 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 1mm 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 an open-loop control circuit (OLCC) configured to determine a photodiode element (PDE) drive voltage as a function of a commanded photodiode gain level and a measured temperature signal. In an illustrative example the OLCC may receive a current temperature of an APD element. The OLCC may, for example, receive a commanded gain for the APD relative to a predetermined reference gain. The OLCC may, for example, retrieve a predetermined efficiency characteristic (PEC) of the APD based on the current temperature. If the temperature corresponds to a substantially non-linear portion of the PEC, the OLCC may, for example, determine the drive voltage as a function of the temperature and the commanded gain based on the PEC. Various embodiments may advantageously provide direct control of output gain of photodiodes over a wide dynamic range of temperature associated with the photodiode.

    Abstract: Apparatus and associated methods relate to a safety control system having a processor that (1) automatically interrogates a portable data storage device, (2) determines whether a configuration profile of the safety control system matches a stored configuration profile in the portable data storage device, (3) obtains network settings of the safety control system, and (4) stores network settings into the portable data storage device. In an illustrative example, a safety control system may include a processor designed to perform operations to configure the safety control system with a configuration profile stored in the portable data storage device or download network settings of the safety control system to the portable data storage device under some predetermined conditions. By using the above method, the safety control system may be quickly configured, and network settings may be easily obtained and backed up.

    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 field selectable gain mode system. In an illustrative example, an APD-based sensor may, for example, have two or more predetermined gain modes. The gain modes may, for example, be activated in response to a selection signal(s) generated by a user. For example, the APD-based sensor may apply the user-selected gain mode by independently controlling a circuit gain, an emitter gain, and an APD gain. When the user selection signal is selected, for example, a controller may apply corresponding independent gain parameters to the circuit gain, the emitter gain, and the APD gain, such that a collective high dynamic range sensor system is provided. For example, the independent gain parameters may include a range of control voltages, a range of control current, and/or a range of gain input. Various embodiments may advantageously achieve increased accuracy across an extended operating range of gain values.

    Abstract: Apparatus and associated methods relate to a networked system having a master and multiple slaves, where each slave stores a unique (actual) slave address and a non-unique (virtual) slave address in memory, such that each slave is configured to respond to request messages addressed to the slave's non-unique slave address if a sensor device associated with the is in an active state when the slave receives the request message. In an illustrative example, the networked system may be a Fieldbus-style network (e.g., a network implementing the Modbus protocol). A sensor device may be a break-beam, capacitive touch, or push-button device, for example. An output indicator/ actuator may be associated with a sensor device to indicate the status of the sensor device to a user. A networked system implementing sensor-activated response gating may beneficially expand the number of slave devices on the network while achieving low latency response times.
