Abstract: An improvement in a laundry dryer system using recovered waste heat from the hot air exhaust of the dryer to transfer that heat to the incoming ambient fresh air. A home laundry dryer in which both the fresh air entering a laundry drum and the air exhausted from the drum pass through thermal recovery ducting. The dryer heat recovery system has concentric ducting including a high temperature passage through which the exhaust air flows and a separate low temperature passage through which the entering air flows. Heat from the exhausted air is transferred from the high temperature passage to the entering air in the low temperature passage. This heat transfer lowers the energy required to raise the entering air to a desired drying temperature. The dryer ducting is designed to have an outer diameter equivalent to standard size ducting on home dryers.

Abstract: Methods and apparatus are provided for testing to determine the existence of defects and faults in circuits, devices, and systems such as digital integrated circuits, SRAM memory, mixed signal circuits, and the like. In particular, methods and apparatus are provided for detecting faults in circuits, devices, and systems using input control signals to generate controlled-duration, controlled pulse-width, transient power supply currents in a device under test, where said transient power supply currents are of controllable bandwidth and can be used as observables to determine faulty or defective operation. Additionally, methods and apparatus are provided to permit high bandwidth sensing of transient supply currents as need to preserve the narrow widths of these current pulses. These methods may include autozero techniques to remove supply current leakage current and DC offsets associated with practical current sensing currents.
