Abstract: A mobility device configurable in a first walk configuration and a second stair-climb configuration, including a frame with movable front leg portions, a leg-actuation system connected to the front leg portions and a safety-control device mounted to the frame. The safety-control device includes a configuration selector, and a lever connected to the leg-actuation system and configured to actuate the cable actuation system so as to cause the first and second movable leg portions to move from a first position to a second position. The lever remains locked in a first lever position such that the lever cannot be moved unless the configuration selector is in a depressed position, thereby preventing inadvertent movement of the leg portion.

Abstract: A guide conduit (900) for delivering analgesia to a target site during a surgical procedure. The guide conduit defines a channel for directing a catheter (975) to an epidural target site cephalad a surgical opening for the injection of analgesia after the surgical opening is substantially closed. An angle (937) formed in the guide conduit functions to urge the catheter toward a bone and away from a thecal sac as it is passed toward the epidural target site. In one embodiment, a finger rest (1040) on a first member (1002) cooperates with a thumb rest (1018) on a second member (1004) of the guide conduit to allow the surgeon to activate sliding disengagement of the two members with one hand to allow the guide conduit to be removed from the surgical site without dislodging the catheter.

Abstract: A tire includes an annular body of elastomeric material that includes a middle radial region. A plurality of unpressurized cavities are defined by the middle radial region and are distributed in a pattern that includes a first radial band of cavities and a second radial band of cavities. Each cavity of the first radial band of cavities is oriented at a positive angle with respect to a radius therethrough, and each cavity of the second radial band of cavities is oriented at a negative angle with respect to a radius therethrough.

Abstract: A work machine tire includes an annular body of elastomeric material that includes a middle radial region. A plurality of unpressurized cavities are defined by the middle radial region and are distributed in a pattern that includes a first radial band of cavities and a second radial band of cavities. Each cavity of the first radial band of cavities is oriented at a positive angle with respect to a radius therethrough, and each cavity of the second radial band of cavities is oriented at a negative angle with respect to a radius therethrough. A material volume of the middle radial region is more than one and a half times greater than the combined void volume of the plurality of cavities.

Abstract: A draped table (10) for an operating room providing a cantilevered over-patient instrument surface (12) that can be swiveled away from the operating field without moving the base (20) of the table. The table remains stable because it has a center of gravity that remains over the base when the instrument surface supports a design load in the over-patient position. The instrument surface may have two levels (38, 40) with a variable degree of overlap between the levels to form an instrument surface of a desired area. A sterile drape (60) covers the instrument surface. The base may include a footpad (24) for a nurse (26) working at the table. Spring-loaded rollers (30) facilitate movement of the table across the floor (34) while withdrawing under the weight of a nurse standing on the footpad to provide unmoving contact between the base and the floor when the table is in use.

Abstract: The present invention provides a method and apparatus for carrying signals having different frequencies in a space-deployed antenna system. When the antenna system is in a first mode, DC power, command information and RF signals (1) are multiplexed via a multiplexer, (2) propagate along a RF transmission line and (3) are appropriately demultiplexed by a demultiplexer associated with each T/R module. Similarly, when the antenna system is in a second mode, telemetry data and RF signals (1) are multiplexed via a multiplexer, (2) propagate along the RF transmission line and (3) are appropriately demultiplexed by a demultiplexer at a driver stage. By using the RF transmission lines associated with each T/R module to deliver (1) DC power, (2) command data and (3) RF signals in the first mode and to deliver (1) telemetry data and (2) RF signals in the second mode, the DC power and command/telemetry wire harnesses (and their respective conductors) may be eliminated.
