Abstract: Described are locking clips for mechanically coupling parallel members, such as cables, poles, pipes, and electrical conduits. The clips include retaining elements that accommodate the members in respective retaining bays. The retaining elements are flexible so that each member clips into a respective bay. Locking mechanisms associated with the retaining elements limits the flexibility of the retaining elements once the members are installed, and thus locks the members in place.

Abstract: Described are clips for collecting sensors into multi-sensor arrays for insertion into wells and the like. The clips are adapted to easily receive the sensors and provide a lock for securing the sensors once installed. The clips can be adapted for use with elements other than sensors, in particular for applications in which a number of relatively elongated members are to be secured in parallel.

Abstract: Described are modular water sensors designed to speed assembly and otherwise improve manufacturability. Various sensors, modules, and cables communicate via connector systems that employ elastomeric conductors to establish and maintain electrical contact between perpendicular wiring-board surfaces. The elastomeric conductors are held in place using easily assembled systems of clips and retainers.

Abstract: A connector assembly includes a retainer with a slot that supports a strip of elastomeric material. The elastomeric material conducts electricity in one direction, through the retainer, but does not conduct electricity in a second direction along the strip and parallel to a surface of the retainer. In one embodiment, the connector assembly is disposed between a circuit board having first and second electrical contacts and a wiring board having first and second concentric conductors. The elastomeric material conducts electrical signals between the first electrical contact and the first of the concentric conductors and between the second electrical contact and the second of the concentric conductors. The connector assembly is not sensitive to orientation, and is thus easily assembled.

Abstract: A rotatable electrical connector has a pair of wiring boards. Each wiring board supports two (or more) concentric conductors that have substantially smooth coplanar surfaces. The coplanar surfaces of the concentric conductors on each wiring board define a contact plane. To provide electrical contact between the two wiring boards, each wiring board is positioned perpendicular to an axis of rotation and is supported so that the respective contact planes of the first and second wiring boards are parallel. A resilient member, such as a spring, urges the wiring boards together to establish electrical contact between the respective surfaces of corresponding conductors on the two wiring boards. The above-described wiring boards are included in a circuit module that also includes a printed circuit board, or other electrical component, sandwiched between a pair of the wiring boards.
