Abstract: Electroacoustic battery sonication rehabilitates a battery by decreasing metallic shorting across battery elements through sonication. Sonication may be produced by application of an electrical signal of selected frequency to the terminals of a battery, thereby establishing a resonant condition within the battery. Alternately, sonication may be provided by transducers placed within a battery and receiving a drive signal of selected frequency to establish a resonant condition within the battery. By removing metallic shorting, e.g., lead hydrates in the case of a lead acid battery, undesirable electrical conduction between battery plates diminishes and battery charging efficiency and capacity increase.

Abstract: A heater includes an aluminum die cast body defining an enclosure and an adaptor block. A heating element within the enclosure activates, under control of an associated heat sensing device, a heating element within the enclosure to transfer heat energy into the adaptor block. The adaptor block, including features specific to a given mechanical device, e.g., pneumatic valve or pump, transfers the heat energy into the mechanical device to avoid a frozen condition resulting from, for example, sudden expansion of air when passing through the device.
