Abstract: Techniques for utilizing excess heat generated by an oven to generate electricity are provided. In one example, an oven can comprise a coolant pathway positioned adjacent to a hollow space within the oven, wherein the hollow space can contain heat. The oven can also comprise a chamber in fluid communication with the coolant pathway. The oven can further comprise a turbine in fluid communication with the chamber and an outlet. Moreover, the oven can comprise a generator connected to the turbine, wherein rotation of the turbine can power the generator.

Abstract: A SIM card holder for a cellular telephone having enclosing front and rear covers and a printed circuit board, includes a base mounted in the cover, the base having a slot for receiving a SIM card on a shelf bordered by side and end walls. The slot opens into the battery compartment of the telephone. A plurality of electrical conductors are mounted in the base, each conductor having a card contact disposed on the shelf and a terminal extending from the base for connection with the printed circuit board in the telephone. An ejector is disposed for sliding movement on the base, which includes a body having an abutment wall for cooperation with an edge of the SIM card, and a button for manipulation of the ejector, the button extending from a slot in the cover.
