A system that includes a desk top assembly of a display and sensors mounted on a robotic arm. The arm moves the assembly so that it remains within position and orientation tolerances relative to the user's head as the user looks around. Near-field speaker arrays supply audio and a microphone array senses a user's voice. Filters are applied to head motion to reduce latency for arm's tracking of the head. The system is full duplex with other systems allowing immersive collaboration. Lighting and sound generation take place close to the user's head. A haptic interface device allows the user to grab the display / sensor array and move it about. Motion acts as a planar selection device for 3D data. Planar force feedback allows a user to “feel” the data. Users see not only each other through display windows, but can also see the positions and orientations of each others' planar selections of shared 3D models or data.

Friction stir fastener equipment and method in which a series of friction stir rivets are rotatably mounted in a supply station and a computer controlled arm terminating in a rotating working head having special gripping jaws that precisely locates and grips a selected rivet. The arm then moves the rotating rivet and progressively drives it into the work until a frictionally heated and plasticized zone of material around the shank of the rivet begins to solidify. The jaws then release the rivet from the drive so that the rivet rotation decelerates to zero. Sufficient hardening of the zone effects the completion of one stir riveting cycle which may be automatically repeated.

A power-operated system for actuating the liftgates of motor vehicles is disclosed. The system includes a controllable strut with internal locking structure that includes a driver and a valve assembly. The controllable strut is typically mounted on one side of the liftgate between the liftgate and the vehicle's frame. Conventional strut may be mounted on the other side of the liftgate. One end of each strut is connected to a powered articulating arm. To move the liftgate between open and closed positions, the articulating arms move the controllable strut and the other strut between positions of greater and lesser mechanical advantage. During the movements, the locking structure in the controllable strut may be activated and deactivated either cyclically or continuously to momentarily to retain the controllable strut as particular lengths.

A conventional monoplane mouse is constructed to move on a flat surface upon a single plane within which a contained sphere may rotate tangential with the single plane contacting the flat surface. Signal for XY cursor movement are derived from two or more counting sensors positioned at an equator of the rotatable sphere parallel with the single plane. The mouse invention defines two or more facets in the underside housing. The facet mouse can be tilted to one of the exclusive facets and moved on a flat surface to generate XY signals. The facet plane selected by tilt is identified by triggered pressure sensitive switches at each facet plane. The switches also function as undercarriage feet to define the virtual plane of contact to the flat surface. The facet planes in two and four facet embodiments are oriented with the orthogonally placed sphere counting sensors so that the interest of any two opposing facets is parallel with the plane of rotation of one of the counting wheels. A single sphere and counter apparatus can serve all facets, being placed at the intersect of all facets. To aid the hand in applying continuous downward pressure to the mouse onto a preferred facet, a hinged and elevatable palm hood is attached to the top of the mouse. The mouse enables a new user interface beyond the tradition ones of: 1.clicking keys by a finger and 2.whole arm movement of a mouse on an XY surface. By a tilting wrist motion, the user may instantly and continuously toggle 2,4, or more selection assigned to the facets provided.

Located within a GFCI is a movable contact bearing arm which cooperates with at least one fixed contact. When the movable arm is moved up to allow the at least one contact on the arm to close with at least one fixed contact, the GFCI is in a conducting state and current flows from a source of electricity through the closed contacts to a load and to the contacts of a receptacle. When the movable arm is moved down to open the contacts, the GFCI is in a non-conducting state and current cannot flow from the source of electricity to either the load or the receptacle contacts. In this invention, the up and down movement of the movable contact bearing arm is harnessed to move a blocking member located within the housing of the GFCI to a first position to block at least one opening of the receptacle as the movable arm is moved down or to a second position to allow the prongs of a plug to enter the openings of the receptacle as the movable arm is moved up. The downward movement of the movable contact bearing arm occurs when the GFCI goes into a non-conducting state. Resetting the GFCI by pressing in and then releasing a reset button causes the movable contact bearing arm to move up to make contact with the at least one fixed contact. As the movable arm moves up, the blocking member moves to the first or non-blocking position to allow the prongs of a plug to freely enter the openings in the face of the receptacle. GFCI's normally have two separate sets of internally located contacts known as bridge contacts where one set is used to connect a load to the source of electricity and the second set is used to connect a user accessible load to the source of electricity. The bridge contacts provide isolation between the conductors to the load and the conductors to the contacts of the GFCI receptacle when the GFCI is in a non-conducting state. In the GFCI here disclosed, the blocking member prevents the prongs of a plug from entering the receptacle when the GFCI is in a non-conducting state and, therefore, the need for the bridge contacts is diminished.

The present invention pertains to extension arm apparatuses that are adapted to support user devices throughout a range of positions. A given apparatus may include one or more arms that position the user device remotely from a support position. An extension and retraction device such as a gas cylinder is received within each arm, and provides a force to support the user device as the arm is placed into a given position. A variable force clevis is connected to the extension / retraction device within the arm. The variable force clevis is connected to a pair of locations in the arm as well. As the arm moves, for instance up or down, the variable force clevis rotates within the arm and dynamically adjusts the force provided by the extension / retraction device. Removable and / or pivotable covers are provided for managing cables of the user device attached to the extension arm.

A furrow opener apparatus includes a parallel link trailing arm having a rear link that is maintained substantially horizontal as the arm moves up and down. Front and rear furrow openers are attached to the rear link. A packer wheel arm is attached to the rear link and extends rearward and downward from the rear link, and a packer wheel is mounted to the packer wheel arm and aligned with one of the furrow openers. A bias device exerts a downward bias force on the trailing arm, furrow openers, and packer wheel. The furrow openers, the packer wheel, and the rear link are maintained in rigid orientation with respect to each other when in a working mode, and a vertical operating position of at least one of the furrow openers with respect to the packer wheel is adjustable to vary a depth of the furrow.

A shaped member having at least one window is located within a GFCI protected receptacle and is operated by movement of the contact arm of the GFCI to assume a first position to block at least one plug receiving opening in the receptacle and a second position which locates the window to allow the prong of a plug to freely enter the face of the receptacle. In operation, when the circuit interrupting device goes into a tripped state, the contact arm moves down to open the circuit. The downward movement of the contact arm, acting through a connecting linkage causes the shaped member to move to the first position, that of blocking at least one opening in the face of the receptacle. Resetting the circuit interrupting device by pressing in and then releasing the reset button of the GFCI causes the main contacts in the circuit interrupting device to close by the upward movement of the contact arm. As the contact arm moves up, it moves the connecting linkage to position the window of the shaped member to allow the prongs of a plug to freely enter the openings in the face of the receptacle. GFCI's normally have two separate sets of internally located contacts known as bridge contacts, one set for connecting a load to the source of electricity and a second set for connecting a user accessible load to the source of electricity. In the GFCI here disclosed the bridge contacts have been eliminated, thus reducing the cost of manufacture by coupling the conductors for both the load and the user accessible load to a single set of contacts.
