Other embodiments include a method comprising obtaining tire pressure and signal strength information from each of a plurality of wireless transceivers respectively coupled to a plurality of wheels included in a vehicle; and detecting, using one or more processors, removal of one of the wheels from the vehicle based on the signal strength information obtained from the wireless transceiver included in the removed wheel.

A method includes, receiving, by a monitoring server, weather data that corresponds to at least one weather condition at a location where a monitoring system monitors an item that is located at an outdoor location of a property and that includes a motion beacon, based on the received weather data, determining a motion tolerance for determining whether a force other than weather likely caused movement of the item, receiving, from the motion beacon, motion data that indicates motion of the item, comparing the motion data to the motion tolerance, based on comparing the motion data to the motion tolerance, determining whether to generate a monitoring system event indicating that a force other than weather likely caused the movement of the item, and performing the monitoring system event indicating that a force other than weather likely caused the movement of the item.

A motion sensing device includes an attachment mechanism configured to quickly and easily attach to an object, a motion detector configured to detect motion of the object, a short-range wireless communication component configured to communicate motion information related to the detected motion, and an indicator.

A tracking system determines if a tracking device is located within a safe zone based on whether a set of safe conditions are satisfied. The set of safe conditions includes a geographic boundary or a geographic location and corresponding threshold distance. The set of safe conditions can also include a time window during which a safe zone is active. When a tracking device is within a safe zone (e.g., geographically and temporally), the tracking device is determined to be safe, and notifications associated with the tracking device can be minimized. The safe zones may be user-selected, user-defined, or determined based on data analytics. If a set of safe conditions are not satisfied, the tracking system generates and sends a notification to the user of the tracking device indicating that the tracking device may be lost.

A user location notification system and a method thereof are provided. The system includes: a first signal transmitting device, a first sensing device, a second sensing device, and a server. The first sensing device and the second sensing device are deployed in a first place. The first signal transmitting device transmits a first signal related to a first user. The first sensing device detects the first signal and transmits a first message according to the first signal. The second sensing device detects the first signal and transmits a second message according to the first signal. The server receives the first message and the second message and sends a first notification message to a first electronic device according to the first message and the second message, wherein the first notification message indicates that the first user is at a specific location in the first place.

A method for determining cause of a disconnection between a computing device of a motion tracking system and one or more sensors of the system, the sensors arranged on a person's body, the computing device configured to at least receive data through a wireless communications connection. Each sensor is configured to at least transmit data through the connection. The method includes measuring a signal strength of the connection with each sensor while the communications are established; processing signal strength values corresponding to a sensor when it has been disconnected from the computing device to determine if the sensor has been disconnected due to a distance increase between the person and computing device; and providing or commanding the provision of at least one user perceptible signal when the computing device has determined that at least one sensor has been disconnected due to a distance increase between the person and computing device.

Laser systems are provided with a semiconductor laser having an emission face, a drive circuit adapted to supply electric energy to the semiconductor laser to cause the semiconductor laser to emit a beam; a user input system adapted to sense a user input action; a controller adapted to control the drive circuit based upon the sensed user input action; a housing within which the laser is positioned and having an opening with a window through which the semiconductor laser can emit the beam. The semiconductor laser is positioned to emit the beam through the window and the emission face of the semiconductor laser is sized to cause a divergence in the beam to create a patterned emission with a predetermined shape without passing the beam through beam shaping optics.
