  • Patent number: 9004925
    Abstract: A connector assembly utilizes improved capacitive coupling for connecting together electrical circuits on two substrates (7, 8). The connector assembly includes first (2) and second (3) connectors respectively attached to first and second circuit substrates. The first connector includes a plurality of first conductors (25) connected to circuits (75) on the first circuit substrate and these conductors have exposed contact surfaces with a dielectric material (4) disposed thereon. The first conductors and associated dielectric material confront second, opposing conductors (35) supported by the second connector frame when the connector frames are engaged together. A liquid dielectric material (45) is interposed between the terminals and the dielectric portions that fills minute gaps which may occur in the dielectric portions to improve the capacitive coupling ability of the connector assembly.

    Abstract: Various contact systems and methods for manufacturing and using such are disclosed herein. Examples of the contact systems include a surface with one set of pads biased at a first voltage level, and another set of pads biased at a second voltage level. Such a contact system can be used, for example, to transfer power to an electromechanical device disposed thereon. In one particular example, the electromechanical device can include a power storage element and two or more couplings. When one of the couplings contacts a pad biased at the first voltage level, and another of the couplings contacts a pad biased at the second voltage level, a circuit is completed where some derivative of the differential between the first voltage level and the second voltage level is placed across the power storage element. Completion of the circuit causes the power storage element to charge. Power can be drawn from the power storage element to operate the electromechanical device.

  • Patent number: 6641434
    Abstract: A robust, low-loss wired pipe joint is provided for service as a component of a wired pipe string for transmitting measurement data to a surface station from locations in a borehole in oil well drilling and oil well operations. Conductive layers reduce signal energy losses over the length of the drill string by reducing resistive losses and flux losses at each inductive coupler. The wired pipe joint is robust in that it remains operational in the presence of gaps in the conductive layer. A wired pipe joint includes an elongate tubular shank having an axial bore, a threaded box-end, and a threaded pin end.

  • Patent number: 6590395
    Abstract: A connector device for a sensor or actuator is composed of two terminal elements releasably connected to one another. A first of these terminal elements including a first electrical conductor that is connected to the sensor or actuator and a second of these terminal elements including a second electrical conductor that is connectible to an evaluation unit. The two electrical conductors are fashioned as coil systems in the terminal elements that enable signal transmission by inductive coupling given a connection of the two terminal elements. Each of the coil systems is formed of at least two series-connected coils that have oppositely directed windings and that are dimensioned such that the sum of voltages induced in the coils by a uniform electromagnetic field yields zero for each of the coil systems. The present connector device can be advantageously utilized for the connection of surface coils to the system of a magnetic resonance system and enables a complete hermetic sealing of the surface coils.

  • Patent number: 5977841
    Abstract: An RF connector comprising a coaxial transmission structure that transmits RF power at RF and microwave frequencies through a dielectric seal. Portions of the connector on either side of the seal do not make metal to metal contact. The connector has input and output connector portions having outer conductors coaxially disposed around inner conductors with dielectric material disposed therebetween. Impedance matching transition portions abut each side of the dielectric seal that have a relatively large diameter adjacent the dielectric seal that transitions to a relatively small diameter distal from the dielectric seal. Tapered and stepped impedance matching transition portions may be employed. A shunt capacitance is disposed approximately one quarter wavelength from each side of the dielectric seal in the stepped transition version. RF energy transmitted by way of the input connector portion is capacitively coupled through the dielectric seal to the output connector portion.

  • Patent number: 5856710
    Abstract: An apparatus for transferring power and communication data across an annular gap comprises an inductively-coupled primary coil winding and secondary coil winding rotatable therein. Two signal oscillators are electrically coupled to a transistor for controlling current flow through the primary coil winding, thereby inducing a signal with a respective frequency in the secondary coil winding. An electronic switch operates so as to apply one of the two signals to the transistor for charging a capacitor coupled to the secondary coil winding, and operates so as to apply the other of the two signals to the transistor for discharging the capacitor. Actuation of control devices operate so as to modulate the impedance of the secondary coil winding. The inductive coupling of the two coil windings results in this modulation being mirrored by a modulation of the voltage developed across the primary coil winding.

  • Patent number: 5711558
    Abstract: A locking mechanism for locking a first member that is inserted into a second member into a first member, such as to secure an inductive coupler in a charge port while it is used to charge an electric vehicle. The locking mechanism prevents premature or malicious removal of the coupler before charging has been completed. The locking mechanism has logic that allows a user to set the lock in the charge port prior to insertion of the coupler. The locking mechanism has an actuator coupled to a rotatable link that is rotated thereby. A first pin is coupled to the rotatable link and a hole disposed in the first member that mates with the first pin to lock the inductive coupler in the charge port. A spring loaded release mechanism coupled to the first pin that permits the first pin to slide into the hole. Motion of the cable and the release mechanism releases and locks the first pin in the hole, or retracts the first pin from the hole, thus locking and unlocking the locking mechanism.
