  • Patent number: 10743871
    Abstract: End effectors with increased clip loading capacity include a housing having a tapered section at a distal end; first and second jaw members protruding distally from the tapered section; a surgical clip feeder arranged within the housing and configured to contain a plurality of surgical clips therein; and a feedbar longitudinally movable between the housing and the plurality of surgical clips, the feedbar having a distal portion engageable with a distal-most surgical clip of the plurality of surgical clips within the tapered section. The plurality of surgical clips is arrangeable within the surgical clip feeder at a non-zero angle with respect to a longitudinal axis of the end effector. Actuation of the feedbar engages and advances the distal-most surgical clip out of the surgical clip feeder and into interposition between the first and second jaw members.

  • Patent number: 10355351
    Abstract: Systems for maintain pointing of a phased array antenna in a direction maximizes to an extent possible the effective antenna gain is provided. The system includes a gyroscope and a Kalman Filter. The Kalman filter estimates an antenna pointing direction for each successive time step based on gyroscope readings and based on the results of a local search for maximum gain performed in the neighborhood of a previous antenna pointing direction.

  • Patent number: 10222445
    Abstract: A system includes a phased array antenna that is used to emulate antennas that have larger solid angle coverage and lower gain compared to a single beam of the phased array antenna. This is achieved by switching between beams of the phased array antenna while receiving a wireless communication signal and summing representations of signal energy received using the different beams. The system can be used to narrow down the angular coordinates of a transmitting satellite by emulating antenna patterns that cover portions of a search space. The system can also be used to determine a channel discriminator (e.g., frequency, code, time slot) that defines a signal being transmitted.

  • Publication number: 20190059984
    Abstract: An apparatus includes a body, a shaft assembly, an end effector, and an articulation section. The articulation section is longitudinally interposed between a distal end of the shaft assembly and a proximal end of the end effector. The articulation section is configured to flex to thereby provide deflection of the end effector away from the longitudinal axis of the shaft assembly. The articulation section includes a first frame member, a second frame member, and a sleeve. The proximal end of the second frame member is proximal to the proximal end of the first frame member. The sleeve is disposed about the first and second frame members.

  • Publication number: 20190008546
    Abstract: An ultrasonic surgical instrument includes a body, a shaft, an ultrasonic transducer, a waveguide, and an end effector coupled to a distal end of the shaft. A rotation knob is rotatably coupled to the body and is configured to rotate the shaft, the waveguide, and the end effector together relative to the body. A torque transfer structure is positioned radially outwardly of and in direct contact with the waveguide at an acoustic node thereof. The torque transfer structure is rotationally fixed relative to the waveguide and is configured to rotationally couple the waveguide with the shaft and the rotation knob. The waveguide includes a first axial constraining feature defining a distally facing surface, and the torque transfer structure includes a second axial constraining feature defining a proximally facing surface configured to abut the distally facing surface to constrain the waveguide axially relative to the torque transfer structure and the body.

  • Patent number: 10103433
    Abstract: A phased array antenna for an earth terminal for a low earth orbit satellite communication system. The phased array antenna includes a set of Quadrafilar Helical Antenna's (QHAs) elements that produce a peak directivity far off-axis which partially compensates for the angular dependence of satellite systems gain which peaks at relatively lower angle. To attain the desired angular dependence of the gain and operability at high zenith angles, the QHAs are preferably spaced apart by a distance between 0.4? and 0.45?, includes filaments that have a helical pitch angle ? of between 62° and 84°.

  • Patent number: 10038235
    Abstract: A multi-mode, multi-band antenna system for a handheld wireless device includes a Quadrafilar Helix Antenna (QHA) that radiates circularly polarized waves is fed by a co-axial cable. The co-axial cable is also used in combination with the QHA as a monopole antenna. Because of the distinct electromagnetic field patterns of the QHA versus the combination of the QHA and the co-axial cable operating as a monopole antenna, the cross coupling between the two modes is low. In certain embodiments the co-axial cable can itself be formed into a helix in order to reduce the physical length of the antenna system while maintaining an electrical length desired to supported certain frequency bands in the monopole mode. According to certain embodiments a post which also serves to increase the effective electric length of the co-axial cable and thereby support a lower frequency band is provided along the centerline of the QHA.

  • Publication number: 20180048382
    Abstract: A mobile satellite radio equipped with a phased array antenna configures the phased array antenna in one or more non-directional operating modes in order to initially detect a signal from a communication satellite. Once a signal has been received from the satellite, frequency information determined in the course of operating in the one or more non-directional modes is used to configure the mobile satellite radio for operation in a subsequent stage when the phased array antenna is configured in a directional mode. In the subsequent stage the phased array antenna is used to scan a solid angle space to determine the direction of the satellite. Thereafter the antenna is used in the directional mode for satellite communication.
