摘要： An energy conversion and transmission device is disclosed which, in its preferred embodiment, has a rigid substrate with a resistive area printed on its top surface, a spacer of non-conductive material with an aperture therethrough positioned in register with the rigid substrate resistive area, and a flexible substrate with a resistive area printed on its bottom surface in register with the aperture and the rigid substrate resistive area so that application of a force to the flexible substrate with an elastomeric actuator will move the flexible substrate resistive area to establish an electrical contact area with the rigid substrate resistive area, which electrical contact area increases and, thus, the resistivity of that area decreases as the applied force increases. Thus, when an electrical potential is applied across the two resistive areas, current flow through the two resistive areas increases as the applied force increases. Capacitive, inductive and other embodiments of the device are also disclosed.

摘要： A membrane switch is formed of an upper layer of electrically insulating material, a lower layer of electrically insulating material, and an intermediate layer of electrically insulating material interposed between the upper layer of electrically insulating material and the lower layer of electrically insulating material. A first electrically conductive layer is printed upon the lower surface of the upper layer of electrically insulating material. A second electrically conductive layer is printed upon the upper surface of the lower layer of electrically insulating material. A resistive component is printed upon an end portion of the second electrically conductive layer. The intermediate layer of electrically insulating material is provided with an opening so as to enable the first electrically conducting layer to initially engage with the resistive component when the upper layer of electrically insulating material is moved downwardly by means of an actuating member so as to produce an electrical connection between first and second switch terminals of the first and second electrically conductive layers which exhibits low current flow corresponding to a first slidable position of the actuating member, while when the actuating member is slidably moved further in the same direction, direct connection between the first and second electrically conductive layers, without the resistive component being interposed therebetween in a series manner, is established so as to exhibit higher current flow between the first and second electrically conductive layers and within the electrical circuit.

摘要： The device described herein is useful in applications which formerly required both a thermal cut-off device and an electrical fuse. This device will open an electrical circuit in response to either an increase in ambient temperature or an increase in electrical current. A bracket is provided to support a radial lead thermal cut-off device. The bracket is of a general C-shaped configuration and has an extending lead bar that is crimped into electrical engagement with an input lead, and one radial lead of the thermal cut-off device is crimped into electrical engagement with the second input lead. A helical conductive coil has one end welded or otherwise secured to the C-shaped bracket, and the second lead of the thermal cut-off device is crimped to the other end of the helical coil which is positioned over the thermal cut-off device so as to surround it. Thus, an ambient temperature rise may cause the thermal cut-off device to open the electrical circuit; or alternately the heat generated by the I.sup.2 R loss in the coil due to excessive electrical current flow may cause the device to also open.

摘要： An electrical apparatus configured for predetermined encoding. The apparatus is comprised of a substrate, a plurality of pairs of electrical terminals affixed to the substrate, a plurality of conductive circuit traces connecting respective pairs of terminals, and a like plurality of removable plugs in the substrate intermediate respective pairs of terminals. The conductive circuit traces respectively traverse respective plugs intermediate respective pairs of terminals so that removal of a plug interrupts the electrical continuity of the conductive circuit trace traversing that plug, thereby creating an electrical open circuit between the respective terminal pair. In such manner, logical "zeroes" (opens) can be created in the respective terminal pairs or, by electing not to remove a given plug a logical "one" (closed electrical circuit) can be programmed between a given electrical terminal pair. While the apparatus is intended, in its preferred embodiment, to be a one-time programmable apparatus, field repairs of the apparatus can be effected by replacing a plug with a segment of a conductive circuit trace carried thereon with the segment of the conductive circuit trace aligned with the remaining portions of the conductive circuit trace and effecting electrical connection between the removed segment and the remaining portions of the conductive circuit trace to re-effect electrical continuity between the respective terminal pair.

摘要： A thermal switch device is constructed with an electrical conductive spring cup contact that fits over a ceramic insulator which surrounds one lead of the device. The center of the spring cup contact has a pattern cut in it so that it is flexible, and a metallic, thin flat disc which is placed against the surface of the spring cup contact which forces the flexible portions of the spring cup contact into contact with the head of the lead that supports the ceramic insulator. A conductive cup-shaped housing that is open at one end encloses the entire structure and is in contact with the spring cup contact. The outer ends of the housing being pinched over the ceramic insulator at the open end. A second conductive lead is attached to the outer surface of the conductive housing. A pellet made of a thermally-fusible material is inserted between the housing and the metallic disc so that when it melts the disc moves away from the spring cup contact, thereby breaking the circuit between the spring cup contact and the second lead.

摘要： A one piece plastic fastener for supporting secondary members relative to a thin panel in a shouldered non-circular aperture. The fastener provides a wide distribution of stress loading by a large hook-like prong which is rotated into contact with the backside of the panel by telescoping it through the aperture until the head covers the aperture. A resilient arm extends from the prong into engagement with the edge of the non-circular aperture to prevent unintentional retrograde motion of the fastener. The fastener can be removed, if desired, by introduction of a thin member under the head to unseat the resilient arm.

摘要： A vanity mirror assembly, which can be lighted, and which can be built into a sun visor for an automobile or other motor vehicle. Electrical components including a heat-dissipative component are screen-printed on a polymeric film substrate mounted adhesively to the back face of a glass mirror, which serves as a heat sink for such components. Shards of the mirror tend to be adhesively retained by the substrate if the mirror happens to shatter.
