Abstract: A device, having a container for holding a fluid moving therein and a conductance probe installed therein for providing a conductance signal indicating whether it is in contact with the fluid, features a jiggler arrangement having a jiggler arranged on the conductance probe so as to form a mechanical self-cleaning conductance probe, which responds to movement of the fluid, for wiping the conductance probe to keep deposits from building up on the conductance probe. The jiggler arrangement may include one or more grooves thereon so that the jiggler can be loosely fitted on the tip between one or more retaining rings arranged in the one or more grooves. The jiggler arrangement may include one or more retaining rings snap-fit on the tip for loosely arranging and retaining the jiggler on the tip.

Abstract: A headmount apparatus for mounting vision enhancement equipment thereon which is comprised of a mounting shell having at least one pad, and having at least one mounting surface to which the vision enhancing equipment is mounted, where the pad is configured to contact the subject's head. The headmount apparatus also contains at least one strap attached to the mounting shell for securing the mounting shell to the subject's head, and contains an occipital assembly which is positioned at the occiput of the subject's head, where the occipital assembly is attached by the strap to the mounting shell and is used to adjust the tension in the strap.

Abstract: Correlating observations of objects in the sky to determine an orbit includes identifying an initially identified object, determining if the initially identified object will be identifiable again, and identifying a subsequently identified object. A determination is then made by comparing characteristics of the initially identified object with the subsequently identified object. If the object correlate to one another a path or orbit of the object can be determined using the characteristics of the initially identified object and the subsequently identified object.

Abstract: A method and apparatus for encapsulating one or more small electronic devices, including for example light-emitting diodes, mounted directly on a substrate by providing a three-dimensional formation on the substrate adjacent to the device and injection molding a thermoplastic encapsulating material to cover the device and extend over the three-dimensional formation on the substrate and wherein the encapsulating material mechanically bonds to the three-dimensional formation. A gate plate for use in injection molding a thermoplastic encapsulating material over a small electronic device mounted directly on a substrate including a cavity formed to enclose the device, and a short gate formed entirely within the gate plate having an input for receiving an encapsulating material and an output communicating with the cavity.

Abstract: A first connector (12, FIG. 2) is constructed so when it is unmated from a second connector (14), front contact devices (32) of the first connector are switched from connections to conductors (16) leading to circuit component (70) to connection to a ground plane (110). The first connector comprises a front insert assembly (22) that includes a plurality of front contact devices (32), and a rear insert assembly (50) that includes a plurality of rear contacts (62). When the second connector fully mates with the first one (FIG. 3), the second connector pushes the front insert assembly to a rearward position (22B), against the force of a spring (40), to cause the front contact devices to mate with the rear contacts. When the second connector unmates from the first one, the spring moves the front insert assembly to the forward position. During forward movement, the front contact devices engage the ground plane (110), to thereby ground the front contact devices when they are not mated to the rear contacts.

Abstract: An edge connector (12, FIG. 1 ) of simple construction and small thickness is provided, with a forward end which can receive a card or circuit board (14) and a rear end which can receive a pluggable connector (40), to connect contact pads (70) of the circuit board to terminals (110, 112) of the pluggable connector. The connector includes an insulative housing (16) having a rearward end portion (20) and having upper and lower cantilevered beams (22, 24). The beams extend forwardly from the rear portion, with a gap (26) between them, and with the front end (30) of the gap having an increased thickness to receive the circuit board. A flat flexible cable (34) lies in the gap, with a front (122) that is upwardly bent and received in a slot (124) of the upper beam portion, and with the forward portions of the cable conductors being exposed at their lower surfaces (164).

Abstract: A flexible printed circuit is secured with adhesive to a glass or plastics substrate. Electrical connection between the tracks of the printed circuit and co-operating tracks on the substrate is made by way of conductive fibers with which the adhesive is loaded in such a proportion that no bridging electrical contact is established between laterally adjacent tracks.
