A cleaning robot is provided. The cleaning robot includes a body, a light detection and ranging (LiDAR) module having a LiDAR sensor rotatably supported by the body, a light-emitting display module mounted on the LiDAR module, wherein the light-emitting display module is configured to display an image based on an afterimage effect according to a rotation of the LiDAR module.

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 (δ.sub.1i). Various embodiments may, for example, advantageously prevent the visual indication from responding to perturbations in the detection signal.

A survey system is provided which includes a surveying instrument capable of performing distance and angle measurements of a target attached to a pole, a controller that is attached to the pole and transmits commands from an input unit for inputting commands to the surveying instrument, and an eyewear device capable of displaying an image superimposed on a landscape. Measurement points are displayed by being synchronized with and superimposed on a landscape of a survey site on an eyewear device, and by inputting a command from the controller to the surveying instrument in a state where the controller is attached to the pole, distance and angle measurements of the target are made. Unnecessary turning of gaze and hand movements are omitted, and a survey work can be efficiently performed by the worker alone.

A method for dynamic monitoring of a trailer using a light detection and ranging (LIDAR) system comprising: scanning the trailer using a set of sensors positioned on a tractor towing the trailer to generate a point cloud of the trailer and monitoring an initial set of motion data of the trailer produced within the point cloud, wherein the motion data comprises velocity data related to the trailer. Provided the initial set of motion data is outside a safe operational threshold, instructing the tractor to perform a corrective action that causes a subsequent set of motion data of the trailer to be within the safe operational threshold. Provided the initial set of motion data is within the safe operational threshold, continuing to monitor the initial set of motion data until the initial set of motion data is outside the safe operational threshold.

A laser rangefinder may include a housing supporting an objective optic, an eyepiece optic, and a view-thru display. The view-thru display may be located along an optical path between the objective optic and the eyepiece optic. The view-thru display may comprise a first transparent sheet and a plurality of electrodes disposed on a first inner surface of the first transparent sheet. The view-thru display may be disposed rearward of the objective optic and the eyepiece optic may be disposed rearward of the view-thru display assembly so that a scene or subject can be viewed through the eyepiece optic and a plurality of display elements selectively displayed by the view-thru display assembly are superimposed on the scene or subject being viewed. Information regarding wind in proximity to the laser rangefinder may be presented on the view-thru display.

A ranging system and a mobile platform are provided. The ranging system includes a laser, a coaxial optical lens group, a mirror group, a moving component, and a processing circuit. When the laser emits laser light to the mirror group by using the coaxial optical lens group, the moving component drives the mirror group to rotate, so that the laser light is irradiated to a measured object at different angles, to implement ranging of the measured object. The moving component bears a light object, so that the moving component rotates quickly. Therefore, if the ranging system is installed on a vehicle, the ranging system can implement fast ranging of incoming and outgoing vehicles and meet a ranging requirement of an autonomous driving technology.
