Abstract: Disclosed herein are systems and methods for a method for controlling the temperature of a surface. In some embodiments, the method includes applying a variable input to a heat pump (e.g., a Peltier) in thermal communication with the surface. The variable input may vary about a voltage and may include a powered period and an unpowered period. In some embodiments, the method includes measuring a temperature of an element in thermal communication with the surface, determining, based on the temperature of the element, whether a temperature of the surface is within a safe temperature range for a user in thermal communication with the surface, in response to determining the surface is not within the safe temperature range, adjusting the voltage of the variable input to the heat pump, and in response to determining the surface is within the safe temperature range, continuing operation of the variable input at the voltage.

Abstract: Pet hair removers are disclosed herein. In some embodiments, the pet hair remover includes a handle, a collection chamber, a roller, a roller frame, a door, and a blade. In some embodiments, the pet hair remover comprises a protrusion on an exterior, planar surface of the roller, and the roller's rotation is limited by the protrusion contacting the roller frame. In some embodiments, the door is at least partially transparent to provide a view of the collection chamber. In some embodiments, the pet hair remover further comprises a spring that biases the door open, a latch that holds the door closed, and a button on the handle.

Abstract: A drink making device including a hood, a base configured to support at least four bottles, a tower connecting the base and the hood; and a dispenser for dispensing a beverage. The hood includes at least four attachment connectors. Liquid from the bottles is selectively pumped through the connectors through the dispenser to dispense a beverage.
