Abstract: An apparatus for linking a surgical instrument with a rigid frame includes a clamping unit comprising (i) a clamp-actuator and (ii) two opposing clamps attached bilaterally to the clamping unit. Either one of the two opposing clamps can be individually effective, to clamp the clamping unit to the rigid frame. A mediating member is provided for mediating between the surgical instrument and the clamping unit, and is proximally engaged with the clamping unit. Force-transfer mechanisms such as, for example, gearing arrangements, and a plurality of mechanical actuators such as, for example, gear-actuators placed to actuate them, are provided for vertically displacing the mediating member relative to the clamping unit and for pivoting the mediating member in intrinsic rotation in a pitch axis.

Abstract: A positioning system for a robotic-surgery device comprises a lower portion comprising a pillar section extending from a wheeled base, an upper portion supported by the pillar section and comprising a docking interface adapted for securing thereto a motor-control unit of a robotic-surgery device, and electronic circuitry programmed to cause the upper portion to simultaneously displace vertically and pitch about a pitch-axis member mediating between the pillar section and the upper-portion, in response to a remote user input, so as to pivot a robotic-surgery device secured to the docking interface about a distal end of a surgical arm proximally seated in a surgical-arm-receiving volume of the motor-control unit.

Abstract: A mixer including a first inlet channel, a second inlet channel, a third inlet channel, and a first dividing wall between the first inlet channel and the second inlet channel. A first opening and a second opening are formed in the first dividing wall. The mixer further includes a second dividing wall between the second inlet channel and the third inlet channel with a third opening and a fourth opening formed in the second dividing wall. The first opening is aligned with the third opening along a first axis and the second opening is aligned with the fourth opening along a second axis.

Abstract: A mixer including a first inlet channel, a second inlet channel, and a first dividing wall positioned between the first inlet channel and the second inlet channel. The first dividing wall radially extending from a centerline. The first inlet channel directs material away from the centerline and the second inlet channel directs material toward the centerline.

Abstract: A mixer including a first inlet channel, a second inlet channel, a third inlet channel, and a first dividing wall between the first inlet channel and the second inlet channel. A first opening and a second opening are formed in the first dividing wall.

The first opening is aligned with the third opening along a first axis and the second opening is aligned with the fourth opening along a second axis.

Abstract: A static mixer including a housing, a first inlet channel, a second inlet channel, a first outlet channel aligned with the first inlet channel along a first axis, and a second outlet channel aligned with the second inlet channel along a second axis. The static mixer also includes a first opening between the first inlet channel and the second outlet channel, and a second opening between the second inlet channel and the first outlet channel.

Abstract: Outdoor apparel with a head cover and hand covers protect the wearer from the sun and other outdoor elements. The outdoor apparel comprises material that is resistant to ultraviolet light, traps heat, and is water wicking. The outdoor apparel further comprises a body and sleeves for additional protection from the elements. The hand covers are attached to the sleeves, which are attached to the body. The head cover may comprise an upper cover and a lower cover and be attached to the body. Together the body, head cover, sleeves, and hand covers protect the wearer from the sun and elements while participating in outdoor activities.
