Abstract: Disclosed herein are methods, devices, and systems for automatically detecting a school bus stop-arm violation. For example, one of the methods can comprise capturing videos of a vehicle using a plurality of cameras of a camera hub coupled to a school bus while the school bus is stopped and at least one stop-arm of the school bus is extended. The method can comprise inputting the videos to a vehicle detection deep learning model and to a vehicle tracker running on a control unit communicatively coupled to the camera hub to detect and track the vehicle as the vehicle passes the stopped school bus. The method can further comprise automatically detecting a license plate number of a license plate of the vehicle from portions of the videos using an automated license plate recognition (ALPR) deep learning model running on the control unit and generating an evidence package of the violation.

Abstract: A system with an integrated internal battery, a removable battery, and a power management integrated circuit. The power management integrated circuit is configured to provide power to the image capture device from the removable battery; provide power to the image capture device from the integrated internal battery when the removable battery is disconnected from the image capture device or the removable battery does not have a sufficient charge to drive the image capture device; and recharge the integrated internal battery before the removable battery until the integrated internal battery has a sufficient charge to power the image capture device. The power is continuously supplied to the image capture device from the integrated internal battery while the removable battery is disconnected from the image capture device or does not have sufficient power to drive the image capture device.

Abstract: A method and system for continuously supplying power to an image capture device during an image capture session are disclosed. The image capture device includes an integrated internal battery located internal to the image capture device and a removable battery connected to the image capture device. Power is provided to the image capture device from the removable battery. When the removable battery is disconnected from the image capture device, power is provided to the image capture device from the integrated internal battery. When a new removable battery is connected to the image capture device, power is provided to the image capture device from the new removable battery. Power is continuously supplied to the image capture device from the integrated internal battery while the removable battery is disconnected and replaced with the new removable battery.

Abstract: Methods and systems for auto-detecting and auto-connecting communication protocols with respect to an image capture device connected to an accessory device via an interface cable. A method for seamless connectivity including automatically detecting, by one of an image capture device and an accessory device, of a wired connection between the image capture device and the accessory device via an interface cable, automatically initiating, by the one of the image capture device and the accessory device, processing associated with a communication protocol supported by the image capture device and the accessory device, and automatically connecting the image capture device to the accessory device via the communication protocol when the processing is complete.

Abstract: A battery-disconnect circuit may include a latch, a battery-disconnect subcircuit, and a power-enable subcircuit. The battery-disconnect subcircuit may be configured to control current leakage. The battery-disconnect subcircuit may be connected to the latch. The latch may be configured to maintain a power supply state of the battery-disconnect subcircuit, a no-power supply state of the battery-disconnect subcircuit, or both. The power-enable subcircuit may be connected to the battery-disconnect subcircuit. The power-enable subcircuit may be configured to switch the battery-disconnect subcircuit to the power supply state based on an enable signal. The power-enable subcircuit may be configured to switch the battery-disconnect subcircuit to the no-power supply state based on an off signal.

Abstract: Devices and methods for sharing power between power sources are disclosed. The power sources may be internal to an electronic device, external to the electronic device, or both.

Abstract: A method and apparatus may be used for power source time division multiplex for thermal management and extended operation. The apparatus includes a primary power source, a secondary power source, and a processor. The processor obtains an internal temperature measurement of the image capture device. The processor may determine a thermal zone based on the internal temperature measurement. In an example where the determined thermal zone is a first thermal zone, the processor may be configured to draw power from the secondary power source. In an example where the determined thermal zone is a second thermal zone, the processor may be configured to alternately draw power from the primary power source and the secondary power source. In an example where the determined thermal zone is a third thermal zone, the processor may be configured to draw power from the secondary power source.
