Mobile devices emit signals in Bluetooth, Wi-Fi and cellular (i.e. 2G, 3G, 4G, Edge, H+, etc.). These signals attempt to connect to paired devices, hotspots, cell towers, or other suitable wireless connection points to greater networks. In order to connect to connect to hotspots mobile devices send out identifying data to establish a connection. Hotspots may unobtrusively collect the identification data of the mobile device, and then reject the connection request. The hotspots collect data in real time on the mobile device, and by association, the human carrying the mobile device without having alerted or impeded the human carrier. The system uses analytical software to determine, for example, an approaching unique ID user's presence, history, frequency of visits, duration of presence and so on.

A method of determining wear of a seal element includes rotating a seal plate relative to the seal element and such that the seal plate and the seal element form a rotational sealing interface. The seal element includes an insert embedded in the seal element. A portion of the seal element is worn with a sealing face of the seal plate. The insert is contacted with the sealing face of the seal plate. A portion of the insert is worn to create a wear particle of the insert. The presence of the wear particle in a lubrication oil is sensed with an oil monitoring system.

A vehicle liquid testing system includes a liquid testing apparatus with a form factor of a dipstick. The system includes a sensor that detects a property of a fluid in a vehicle and emits a signal indicative of the property. A transmitter receives the signal from the sensor and transmits the signal. A controller receives the signal from the transmitter and compares the signal from the sensor to a threshold level to determine a condition of the fluid.
