A pedestrian hazard detection system. The pedestrian hazard detection system has a housing that is sized and shaped to receive and secure a mobile device, such as a cellphone, therein. At least one sensor, such as a motion sensor, is disposed within the housing. The sensor can detect obstacles that are approaching and are in the vicinity of the housing. The sensor is operably connected to the mobile device and whereupon the sensor detecting the at least one approaching obstacle, a signal is sent to the operably connected mobile device to emit an alert. The alert can notify a user that the obstacle is approaching such that the user can take appropriate action to avoid a collision.

A method of calibrating a total station having a laser based range finder is disclosed. The method includes the steps of positioning a first subsystem including the total station and a first RTK receiver at a first location and determining that location using RTK location information. A second subsystem having an optical target and a second RTK receiver is positioned at a first remote location and that location is determined by an RTK approach. The distance and azimuthal information between first and second subsystems is determined by the total station. The second subsystem is moved to a plurality of additional remote locations and the determinations are repeated. The results are used to calibrate the total station.

A method, device and system for generating a transformation function, mapping position detections of objects in a scene, detected with a positioning device, to a graphical representation of the scene. The teachings enable the detected positions by the positioning device to be mapped to the graphical representation of the monitored scene without the need of previous references to geographical coordinate systems for the positioning device and the graphical representation of the scene. Virtually any type of image may hence be used as a graphical representation of the scene, even hand-drawn sketches.

A light source module and a display module are provided. The light source module includes: a substrate; a plurality of first light sources spaced on the substrate, each of the plurality of first light sources being configured to emit visible light; a depth sensor on the substrate; and a first blocking member configured to shield visible light but transmit invisible light. The depth sensor includes a second light source configured to emit invisible light and a light receiving member configured to sense invisible light, an orthographic projection of the second light source on the substrate is located within an orthographic projection of a gap between two adjacent first light sources on the substrate, an orthographic projection of the first blocking member on the substrate at least partially covers the orthographic projection of the second light source on the substrate.

Methods and systems for detecting objects in a three-dimensional space. The method includes emitting, by a plurality of transmitters oriented in a respective plurality of directions, signals to produce uniform millimeter wave illumination of the three-dimensional space. The method includes determining object data including a direction, a phase, and a timing of signals reflected from one or more objects within the three-dimensional space. The method includes detecting, by a processor, the one or more objects in the three-dimensional space based on the object data. The method includes rendering, by the processor, an image corresponding to the one or more detected objects.
