A proximity sensing device includes: a light source, a sensing unit, a light guide unit, and a window. The light source emits light, which is guided by the light guide unit to the window. The emitted light reflected by an object is received by the same window. The light guide unit includes a partial-transmissive-partial-reflective (PTPR) optical element, whereby the light emitted from the light source is reflected by the PTPR optical element, while the light reflected by the object passes through the PTPR optical element. There is only one window required.

A ramp system for a vehicle includes a control device. Using an obstacle detection device, the control device determines whether an obstacle exists within a ramp extension area. Upon determining that an obstacle exists within the ramp extension area, the control device causes a vehicle to move to a location in which no obstacle exists within the ramp extension area.

Systems and methods for tracking an object. The method comprising: receiving, by a processor, a series of observations made over time for the object; selecting, by the processor, a plurality of sets of observations using the series of observations; causing, by the processor, the plurality of sets of observations to be used by at least one filter to generate a track for the object (wherein the at least one filter uses sensor data associated with each of a plurality of frames of sensor data only once during generation of the track); and causing, by the processor, operations of an autonomous robot to be controlled based on the track for the object.

An embodiment device includes an optical source configured to transmit an optical pulse and an optical sensor configured to receive a reflection of the optical pulse. The device further includes a processor configured to determine a parameter based on the reflection, the parameter indicative of a distance between the device and a target; and a controller configured to generate a first control signal based on the parameter, the first control signal being configured to control an operation of the optical source.

Various approaches to ensuring safe operation of industrial machinery in a workcell include disposing multiple image sensors proximate to the workcell and acquiring, with at least some of the image sensors, the first set of images of the workcell; registering the sensors to each other based at least in part on the first set of images and, based at least in part on the registration, converting the first set of images to a common reference frame of the sensors; determining a transformation matrix for transforming the common reference frame of the sensors to a global frame of the workcell; registering the sensors to the industrial machinery; acquiring the second set of images during operation of the industrial machinery; and monitoring the industrial machinery during operation thereof based at least in part on the acquired second plurality of images, transformation, and registration of the sensors to the industrial machinery.

An information processing system includes an irradiation unit configured to irradiate a deposited material with electromagnetic waves, a detection unit configured to detect scattered waves or transmitted waves of the electromagnetic waves with which the deposited material has been irradiated by the irradiation unit, and a determination unit configured to determine a state of the deposited material from an image based on the scattered waves or the transmitted waves detected by the detection unit.

A light detection and ranging system can consist of a detector body constructed of Germanium and configured with a Mie resonance. A metal contact and metasurface can each be positioned atop the detector body with the metal contact preventing screening of light to the detector body. Impedance mismatch can be corrected to eliminate reflection from the metasurface.
