This disclosure describes, in part, techniques for generating location information associated with a video. For instance, an electronic device may use a radar sensor to generate radar data. The electronic device may then analyze the radar data in order to determine a location associated with an object. In some instances, the location may correspond to at least a first coordinate along a first axis and a second coordinate along a second axis. The electronic device may also generate image data using the imaging device. Additionally, the electronic device may analyze the image data in order to determine that the image data represents an object and/or a type of object. The electronic device may then generate location data representing an identifier for the object and the location. Next, the electronic device may send the image data and the location data to one or more computing devices.

This disclosure describes, in part, techniques for generating location information of an object along with a video that depicts the object. For instance, an electronic device may include a radar sensor that determines locations of the object. The electronic device may then store radar data representing at least the locations. Additionally, based on detecting an event, the electronic device may begin to generate image data representing the video. The electronic device may then analyze the radar data and the image data in order to determine that the object detected by the radar sensor includes the same object represented by the image data. As such, the electronic device may send the radar data and the image data to one or more computing devices. This way, a user device is able to display both the video depicting the object as well as the location information representing the motion of the object.

This disclosure describes, in part, techniques for displaying location information of an object along with a video depicting the object. For instance, an electronic device may use a radar sensor to generate radar data representing the locations and an imaging device to generate image data representing the video. A user device may then use the image data to display the video. Additionally, the user device may display a map of a geographic area that includes the electronic device over a portion of the video. The electronic device then uses the radar data to determine positions on the map that corresponds to the locations. Using the positions, the electronic device displays interface elements representing the locations of the object. In some circumstances, the interface elements include different characteristics, such as colors, indicating a direction of motion of the object.

A hygiene monitoring and management system including a monitoring module and a display. The management module with an input and that receives data via the input. The received data includes one or more locations of a device in a facility, and the management module further includes one or both of software and hardware configured to generate data representative of cleaning behavior associated with the device based on the received data. The cleaning behavior includes timing and movement of the device in the facility, and a cleanliness level of at least one area in the facility.

An electronic device is provided. The electronic device includes a plurality of antennas to communicate with an external electronic device and at least one processor operatively connected to the plurality of antennas. The processor is configured to detect a tracking start event using an external magnetic material positioned at a location adjacent to the electronic device, to track a location of the external electronic device using the plurality of antennas and, while the tracking is performed, to obtain a height value of the external electronic device when an angle between the electronic device and the external electronic device is a specified angle. The processor is further configured to change a specified condition based on the obtained height value, to detect a tracking end event based on the specified condition, and to change an operating mode associated with the electronic device in response to detecting the tracking end event.

Radar-based sensing includes, at an electronic device that includes one or more radar-based transmitters and one or more radar-based receivers, transmitting, from one or more of the radar-based transmitters, radio waves into an area in a vicinity of the electronic device and receiving, at one or more of the radar-based receivers, radio waves reflected off one or more objects in the vicinity of the electronic device. The radio waves, as reflected off the one or more objects, can be processed using a radar imaging module.

A grouping unit separates, into groups, reflection points included in plural sets of reflection-point information items based on positional parameters of the respective reflection points in a first direction. Each of the positional parameters of a corresponding one of the reflection points in the first direction represents a position of the corresponding one of the reflection points in the first direction. A measuring unit performs a two-dimensional trilateration localization for each of the groups based on at least one reflection point included in a corresponding one of the groups to thereby calculate a location of the at least one reflection point included in each of the groups in a second plane. The second plane is defined by the second direction and a group center direction of the corresponding one of the groups.

Methods and systems for mapping boundaries of a given environment by a processor of a computer system, the method comprising: determining a trajectory of the body in the given environment over the given time period; and determining, based on the trajectory of the body in the given environment, one or more of an outer boundary of the given environment, and an inner boundary of the given environment. Methods and systems for mapping functionalities of a given environment executable by a processor of a computer system, the method comprising determining a pattern of movement of a body in the given environment in a given time period; and determining a functional identity of at least one zone in the given environment based on the pattern of movement of the body to obtain a mapped given environment.

A golf ball tracking system, which includes a distributed sensor and processor system adapted to simultaneously track the trajectories of multiple golf balls hit by one or more golfers. The system is adapted to keep track of the location of the golfers to enable the allocation of shots to the correct golfer. The system is operated at a golf driving range, where multiple players can hit balls from anywhere within a designated area and/or fixed hitting bay locations.

Systems and methods for determining user equipment (UE) locations within a wireless network using reference signals of the wireless network are described. The disclosed systems and methods utilize a plurality of in-phase and quadrature (I/Q) samples generated from signals provided by receive channels associated with two or more antennas of the wireless system. Based on received reference signal parameters the reference signal within the signals from each receive channel among the receive channels is identified. Based on the identified reference signal from each receive channel, an angle of arrival between a baseline of the two or more antennas and incident energy from the UE to the two or more antennas is determined. That angle of arrival is then used to calculate the location of the UE. The angle of arrival may be a horizontal angle of arrival and/or a vertical angle of arrival.
