An indoor-outdoor novelty device which simulates the flight and illumination patterns of real fireflies in dark conditions. The device provides the illusion of a flying illuminated firefly, appearing and disappearing at pseudorandom positions. This behavior provides a realistic firefly effect especially when multiple devices are present. This effect is due to the unique configuration of this device under microcontroller control. The device may be configured as completely self-contained, self-operating and self-charging; not requiring user intervention for daily operation and can be located indoors or outdoors.

Embodiments are disclosed of a battery management system (BMS). The BMS includes a pair of back-to-back transistors configured to selectively discharge battery cells of a battery pack; a high-side driver configured to control operation of the pair of back-to-back transistors; an analog front end (AFE) circuit configured to monitor a voltage of each cell within the battery pack; and a micro controller unit (MCU) configured to control and monitor the AFE circuit and provide over-voltage protection to the pair of back-to-back transistors.

A nanomaterial-based gas sensor system comprising a low voltage circuitry which includes a transducer to detect changes in electrical properties of a multi-channel gas sensor array, analog signal conditioning, and an A/D conversion to provide a signal to a digital back-end.

A system for the maritime shipping industry to aid enforcement of the Sulfur Dioxide (SO.sub.2) exhaust emissions regulations which uses neural networks and a novel sampling process to detect and record compliant operation of a ship regarding the fuel switching aspect of the regulation. The processing load of neural network training can be distributed over multiple identical self-contained, self-powered, self-communicating sensor units on each of the monitored ships.

Example implementations include a method, apparatus, and computer-readable medium comprising first broadcasting, by at least one primary speaker of a control panel, a first sound toward a front or a side of the control panel; and second broadcasting, concurrently with the first broadcasting, by a removable back speaker that is removably attachable to a back side of the control panel, a second sound toward the back side of the control panel. In some aspects, the removable back speaker is configured as a stand for placing the control panel on a flat surface.

A device for providing nicotine replacement therapy may be provided. The device may comprise a processor. The processor may be configured to perform one or more actions. A cessation program for a user may be determined. A program intervention event based on a phase of the cessation program may be determined. A marker associated with the user may be determined. A modification to the cessation program may be determined based on the program intervention event.

An output controller obtains a pair of safety state inputs, and, at each of a first microcontroller and the second microcontroller determines whether the pair of safety state inputs both show an unasserted state. Responsive to determining that the pair of safety state inputs both show an unasserted state, the output controller determining a normal state, and otherwise the output controller determines a safe state. The output controller outputs a binary software command reflecting either a normal state or a safe state, and converts the binary software command to a hardware command that maintains the state of voltage of a circuit where the binary software command reflects a normal state and otherwise switches to a safe state. The controller compares readback output values from the two microcontrollers, and generates an output therefrom.

The present application describes an integrated module. The integrated module includes a microcontroller, an inertial measurement unit (IMU), a low-power accelerometer, and an environmental sensor. A noise target between the IMU and low-power accelerometer is less than a noise target be the IMU and microcontroller. The present application also describes a method of using an integrated module.

Disclosed is an apparatus for running a physical software coding training book. The apparatus includes: a toy control unit being connected to a Micro Control Unit (MCU) via serial communication and controlling motion of a toy through the MCU; a training content processing unit being connected to the toy control unit via HyperText Transfer Protocol (HTTP) and providing training content written in HyperText Markup Language (HTML), the training content including motion control commands for the toy; and a physical software processing unit capable of directly writing block coding-based physical software by embedding a block code editor into the training content and performing control of the toy.

A system for automated equipment cabinet leveling may include a foot leveling device for each foot of an equipment cabinet, each foot leveling device comprising a drive gear and a worm gear; a motor for each foot leveling device, each motor driving the worm gear of one of the foot leveling devices; a controller controlling the operation of each motor; and a sensor positioned on a portion of the equipment cabinet to be leveled that detects an orientation of the equipment cabinet and provides orientation data to the controller. The foot leveling device may interface with a foot shaft of the cabinet foot by a drive shaft driven by the drive gear, and the controller may drive at least one of motors to level the surface of the equipment cabinet based on the orientation data by extending or retracting at least one of the cabinet feet.
