An electronic power module (20) comprising a case (22) that houses a stack (88), which includes: a first substrate (26) of a DBC type or the like; a die (27), integrating an electronic component having one or more electrical-conduction terminals, mechanically and thermally coupled to the first substrate; and a second substrate (29), of a DBC type or the like, which extends over the first substrate and over the die and presents a conductive path (32) facing the die. The die is mechanically and thermally coupled to the first substrate by a first coupling region (30) of a sintered thermoconductive paste, and the one or more conduction terminals of the electronic component are mechanically, electrically, and thermally coupled to the conductive path (32) of the second substrate (29) by a second coupling region (34) of sintered thermoconductive paste.

The invention provides transient devices, including active and passive devices that physically, chemically and/or electrically transform upon application of at least one internal and/or external stimulus. Incorporation of degradable device components, degradable substrates and/or degradable encapsulating materials each having a programmable, controllable and/or selectable degradation rate provides a means of transforming the device. In some embodiments, for example, transient devices of the invention combine degradable high performance single crystalline inorganic materials with selectively removable substrates and/or encapsulants.

A submersible power distribution system (110) is provided. The system includes at least one receptacle (150) configured to be exposed to an underwater environment (105) and a plurality of power conversion modules (152, 158) positioned within the at least one receptacle. Each of the plurality of power conversion modules includes a first enclosure (154) configured to be exposed to the underwater environment, the first enclosure defining a first interior cavity configured to have a first pressure. Power conversion modules also include at least one second enclosure positioned within the first interior cavity. The at least one second enclosure defines a second interior cavity configured to have a second pressure that is lower than the first pressure. The at least one second enclosure is configured to restrict exposure of non-pressure-tolerant power electronics in the second interior cavity to the first pressure.

An apparatus (1) and plurality of sensors where the apparatus (1) comprises: a plurality of coupling elements (7); a plurality of attachment portions (13) configured to enable a plurality of sensors to be removably attached to the apparatus (1); at least one processor (3); and at least one memory (5) including computer program instructions (11); wherein the at least one memory (5) and the computer program instructions (11) are configured to, with the at least one processor (3), enable the apparatus (1) to individually address each of the plurality of coupling elements (7) to obtain a reading from each of the plurality of sensors attached to the apparatus (1).
摘要:
A system for assembling electronic devices includes at least one coating element for applying a moisture-resistant coating to surfaces of a device under assembly, or an electronic device under assembly. As components and one or more moisture-resistant coatings are added to the electronic device under assembly to form a finished electronic device, at least one surface on which the coating resides and, thus, at least a portion of the coating itself, is located internally within the finished electronic device. Methods for assembling electronic devices that include internally confined moisture-resistant coatings are also disclosed.

This method is for producing a sensor unit (6) for sensing the angular position of a rotatable element (42) with respect to a fixed element (44), comprising an encoder element (62) fast with the rotatable element (42), adapted to generate magnetic field variations as a function of its angular position, and a sensing element (640) fast with the fixed element (44), adapted to sense the magnetic field variations. The sensing element (640) is mounted on and connected to a printed circuit board (642) mounted in a shielding casing (66) fast with the fixed element (44). This method comprises a step consisting in earthing the shielding casing (66) by electrically connecting it to a load discharging device of the printed circuit board (642).
