Abstract: A cycling suturing and knot-tying device is characterized by an arcuate fixed, grooved or recessed way provided in a correspondingly-shaped support frame for accommodating a curved needle fitted with thread, and frictional needle-engaging devices provided in the way for selectively engaging the needle and driving the needle in one or both rotational directions to suture a wound with the thread. Selective articulation of the frame and the way and driving of the needle in the way by positioning the frictional needle-engaging devices with respect to the needle are typically effected by manipulation of a pistol-grip operating apparatus having a transmission tube that mounts the frame and the way in articulating relationship and rotates and articulates with respect to the pistol grip and carries various operating elements that interface with the frictional needle-engaging devices in the way.

Abstract: A flow control device having no moving parts that controls fluid flow along a fluid pathway in such a way that flow rate remains constant irregardless of environmental changes. The device achieves a constant flow rate by taking advantage of the properties of the fluid moving along the fluid pathway and maintains the constant flow rate irregardless of changes in viscosity due to changes in temperature.
Abstract: An imaging system for obtaining images of a specimen that includes a novel filtering system for filtering radiation emitted from the specimen. The imaging system includes a camera and a novel filter grid that is controllably movable relative to the camera in a manner to move a selected emission filter of a plurality of emission filters carried by the grid into position between the camera and the specimen. The filter carrying grid of the system resides in a plane having X and Y coordinates and the system includes a novel positioning mechanism for controllably moving the filter carrying grid along the X and Y coordinates of the plane in a manner to position a selected one of the emission filters carried by the grid into position between the camera and the specimen.

Abstract: An adjustable headrest for use with furniture and vehicle seats that includes novel slide mechanisms for permitting easy vertical and horizontal adjustments of the headrest relative to the seat. The headrest also includes wing-like side support members that are pivotally connected to horizontally adjustable slide mechanisms by constant torque hinges. Additionally, the headrest includes a mechanism for permitting pivotal movement of the entire headrest relative to the seat connector which connects the headrest to the seat.
