Abstract: Various embodiments relate to mobile units. A mobile unit may include a number of electronic devices including a processor, a number of loads, and a modem. The mobile unit may further include a circuit board including the processor and logic configured to reset the processor, at least one load of the number of loads, and/or the modem responsive to receipt of a reset signal. The circuit board may also include a power switch-over circuit coupled to the processor and the logic and configured to switch power to at least some of the number of electronic devices from a primary battery to a secondary battery or from the secondary battery to the primary battery. Further, the circuit board may include a charge controller coupled to the secondary battery and configured to limit an amount of current conveyed to the secondary battery. Associated devices and methods are also disclosed.

Abstract: Various embodiments relate to power reset. A system may include a power source and a load configured to couple to the power source. The system may also include a modem configured to receive a first signal from a remote device and generate a second signal responsive to receipt of the first signal. Further, the system may include circuitry. The circuitry may be configured to responsive to the second signal, disconnect the load from the power source for a time duration. The circuitry may further be configured to reconnect the load to the power source after the time duration. Associated methods and mobile units are also disclosed.

Abstract: Methods and systems provided. A system may include a mobile surveillance unit positioned within an environment and including one or more sensors configured to detect one or more events occurring within or near the environment. The system may also include an application program configured to: convey data related to a detected event of the one or more events to an electronic device remote from the mobile surveillance unit; and in response to input associated with the detected event, convey, from the mobile surveillance unit, image data, video data, audio data, or any combination thereof, previously captured at the mobile surveillance unit and associated with the detected event.
