Abstract: An electric toothbrush is disclosed, having a handle including a drive motor and a head portion removably coupled to the handle. The head portion includes a brush, an exit port fed by an internal irrigation lumen, and a drive shaft operatively connecting the drive motor to the brush. A disposable irrigant reservoir is removably coupled directly to the head portion. The irrigant reservoir is in fluid communication with the internal irrigation lumen of the head portion. The head portion is configured to be replaceable with respect to the handle, and the irrigant reservoir is configured to be replaceable independent of the head portion. In some examples, the irrigant reservoir is a disposable bulb (e.g., a capsule), and is positioned such that the user can hold the handle while also squeezing the reservoir with the same hand. In some examples, the toothbrush head includes a suction mechanism.

Abstract: The present invention relates to a vehicular lighting device designed to be removably attached to a front and/or rear portion of a vehicle, and that is designed to signify intended straight-ahead travel of the vehicle. The device is comprised of a plurality of LED strips recessed under opaque glass wherein each LED strip is in a vertical arrow or chevron shape. An operator can selectively activate the lights wirelessly and upon reaching an area where a straight-ahead signal is desired, the operator can activate the system and illuminate the LED strips to visually communicate with surrounding motorists. The lights can automatically deactivate after a predetermined time. The vehicular lighting device can be integrated within or retrofitted to almost any type of vehicle, including but not limited to, cars, pickup trucks, commercial trucks, motorcycles, motorcycle helmets, bicycles, and more.

Abstract: A safe with an integrated low voltage power system includes a transformer and a power distribution system, disposed within the safe. The transformer is configured to convert AC power input to low voltage DC power, and the power distribution system is configured to distribute the low voltage power to DC devices inside the safe. The DC devices can include lights, a safe locking mechanism, alarm devices, sensors, a clock, and a dehumidifying system, such as a heater, a cooler, or an electro-resistively heated rack. The cooler can be a thermo-electric device, configured to cause condensation on a cold plate, and including a drain, configured to direct the condensation to a point outside the safe.
