Abstract: The apparatus and method of the present invention provide an improved low cost and easy to manufacture vacuum-proof shatter-resistant enveloping component, having superior temperature stability, as well as high temperature and mechanical reliability, that is readily usable with any electronic/thermoelectric device that utilizes enveloped vacuum in the operation thereof. In accordance with various embodiments of the present invention, rather than being made from a single layer glass or a ceramic material, the novel vacuum enveloping component comprises a hollow housing fabricated from a thermo-stable metal alloy, and provided with an inner insulating layer composed of a non-conductive material.

Abstract: The present inventive foot-operable apparatus and method comprise a generally rectangular housing comprising at least one internally positioned accelerometer sensor component, and also including at least one pedal-type component oriented toward, and operable by, a user, and advantageously enable the operating user to produce one or more control signals, of one or more types, and within one or more ranges, in response to the user's predetermined interaction(s) therewith. The novel utilization by the present invention of at least one accelerometer sensor component provides it with numerous advantageous features (such as extensive flexibility, ease of adaptation/configuration, etc.), and a wide range of functionality, while facilitating its easier transport and operation, and greatly increasing the reliability thereof.
