Abstract: Electrical and electromechanical devices often require maintaining a specific temperature, or a narrow range or temperatures, during operation. An assembly regulates the temperature of a device by providing a variable thermal resistance between the device and a heatsink. The device can be mounted to a base having a high thermal resistance, the base thermally isolating the device from the heatsink. At low environmental temperatures, the base enables the device to rise to its operating temperature as a result of the device's waste heat, and with no or minimal use of a heater. As the environmental temperature increases, a working fluid, having a low thermal resistance, undergoes thermal expansion to fill a portion of a volume in the base between the device and the heat sink, lowering the thermal resistance between the device and the heatsink to maintain the device at the required operating temperature.

Abstract: A clipper for clipping nails of an animal such as a dog, or cat, that allows for the clipping of an individual nail at the desired length while preventing injury to the animal, including a clipper portion and a sensing portion which allows the nail to be localized in a desired position relative to the clipping plane of the clipper and the internal structure of the nail, wherein the sensing portion is included within circuitry that includes a signal generation portion, a signal reception portion, and a quick indicator. The animal nail is positioned near the clipper portion and the sensing portion produces a sensible signal confirming the position of the clipping plane upon the nail, particularly the quick of the nail. The user then may adjust the position of the clipper portion such that the clipping plane avoids the quick. The user then actuates the clipper portion and trims the nail.
