Abstract:
The present invention provides a miniature liquid transfer pump. The pump has a housing that includes first and second blocks joinable to form a leak-resistant impeller chamber with a drive shaft aperture, an inlet and an outlet. An impeller is located in the impeller chamber and a micro-motor with a drive shaft extending therefrom is mounted to the housing. The drive shaft on the micro-motor passes through the drive shaft aperture and engages the impeller. The micro-motor drives the impeller to draw liquid through the inlet and eject the liquid through the outlet.
Abstract:
The present invention provides an encapsulant structure (130) for retaining an electronic circuit (110) having heat-generating components within a case (120) that at least partially surrounds the electronic circuit. In one advantageous embodiment, the encapsulant structure provides for a thermally conductive insert to be located within the case proximate the heat-generating components. The insert increases the heat transfer efficiency from the electronic circuit to the case.
Abstract:
An improved circuit board apparatus configured for mounting electronic components in a circuit arrangement comprises a metal substrate (22) having a first side (24) and a second side (26), a first-side laminar structure and a second-side laminar structure. The first-side laminar structure includes at least one first-side conductive stratum (32) alternated with at least one first-side dielectric stratum (28) affixed at the first side The second-side laminar structure includes at least one second-side conductive stratum (34) alternated with at least one second-side dielectric stratum (30) affixed at the second side of the metal substrate. The apparatus further comprises a plurality of electrically conductive interside courses (46, 48) intermediate selected first-side strata of the at least one first-side conductive stratum and selected second-side strata of the at least one second-side conductive stratum.
Abstract:
A header (100) includes, in one embodiment, first (110) and second (120) contacts, and an intermediate body (130). The intermediate body includes an insulated section (135) interposed between the first and second contacts and has a cavity therein (140). The intermediate body also includes a semiconductor die (150), located within the cavity, adapted to condition a signal passing through at least a portion of the header.
