Abstract: The present disclosure provides medical devices, particularly medical grade needles with removable tips, as well as methods of needle tip installation and removal, and devices therefor. Needle tip installation and removal devices may include needle tip installation and removal tools and kits, including hand held and manipulated tools that facilitate the installation and removal of needle tips, particularly on vascular access port needles. Such installation and removal devices may provide more expedient hook up of the access port for the therapy. Also, the installation and removal of the needle tips may be conducted in a more sterile manner.

Abstract: A patency system for maintaining a patency of an indwelling medical device including an elongated shaft configured to be at least partially received within a portion of the indwelling medical device, and at least one cleaner configured to at least partially dislodge debris formed within the indwelling medical device.

Abstract: One embodiment relates to an apparatus that includes an illumination source (102) for illuminating a target substrate (106), objective optics (108) for projecting the EUV light which is reflected from the target substrate, and a sensor (110) for detecting the projected EUV light. The objective optics includes a first mirror (202,302, or 402) which is arranged to receive and reflect the EUV light which is reflected from the target substrate, a second mirror (204, 304, or 404) which is arranged to receive and reflect the EUV light which is reflected by the first mirror, a third mirror (206, 306, or 406) which is arranged to receive and reflect the EUV light which is reflected by the second mirror, and a fourth mirror (208, 308, or 408) which is arranged to receive and reflect the EUV light which is reflected by the third mirror.

Abstract: A water craft having an adjustable fin assembly. The fin includes a base having a circular cross-section for rotating within a circular recess formed in a fin box attached to a water board. A means is provided for securing the fin at a predetermined angle of attack. The fin may be secured by a set screw or pin passing through the fin box and making contact with the base. The pin may pass through a hole in the base to provide vertical and rotational support for the fin. The pin may be moved between an engaged position and an unengaged position by the rotation of a gear interfacing with teeth formed on the pin. The fin base and fin box may include mating projections and slots for securing the angular position of the fin and an associated pin for retaining the fin within the fin box.

Abstract: An optical scanning device, for reflecting a light beam produced by a laser light source, having an entrance window; a rotatable scan optic having a reflective surface and a spherical exit window; the reflective surface of the rotatable scan optic positioned adjacent the entrance window and central to the spherical exit window such that the light beam successively encounters the entrance window, the reflective surface of the rotatable scan optic, and the spherical exit window surrounding the reflective surface of the rotatable scan optic, the light beam encountering and passing through the spherical exit window after being reflected away from the rotatable scan optic; the reflective surface of the rotatable scan optic circumscribed by a chamber defined by the entrance window, the rotatable scan optic device, and the spherical exit window.

Abstract: This is a catoptric optical system including afocal and focal embodiments comprising substantially aspheric concave first, convex second, third, and concave fourth reflection means producing an intermediate image between the first and fourth reflection means. In an afocal embodiment, the third reflection means is proximate the internal image produced by the second reflection means and provides aberration control and a compact beam folding function. In an alternate focal embodiment, the second reflection means is proximate the internal image produced by the first reflection means. Significant magnifying power is achieved for the afocal embodiment while minimizing aberration and distortion and providing full spectrum coverage with high image quality. The system provides a wide circular or square field of view with little or no obscuration in a compact envelope.

Abstract: The invention is a method for the on-line nondestructive determination of the internal bond strength of composite panel products. The method involves impinging an ultrasound pulse against the panel by a first transducer and receiving a transmitted pulse at a second transducer. The received signal strength, temperature and panel thickness are entered into an algorithm from which the internal bond may be calculated. Preferably the receiving transducer is located on the opposite side of the panel and displaced somewhat from the first transducer. The inclusion of temperature and panel thickness as independent variables greatly improves the accuracy over that available from uncorrected ultrasound testing.

Abstract: A device for pulling electrical cable through conduit having a rigid frame with two wheels mounted thereon for being moved in a wheelbarrow like fashion and having attached to the frame a motor for driving a torque converter and speed reduced which drive a shaft which is clutched and which has a reel of cable connected thereto in which a guide and support mechanism directs the cable to the reel and support the entire device in a fixed position relative to the conduit through which the cable is being pulled and in which the motor can be remotely controlled by a switch.

Abstract: Apparatus for monitoring strip loop position, having a plurality of light sources and a corresponding plurality of photo-detectors spaced from each other in the strip loop reservoir on opposite sides of the strip loop path; each photo-detector is connected to the input of a corresponding photocell amplifier which is normally biased to be driven to positive or negative saturation as a function of the input voltage applied to the photocell amplifier. The outputs of all the photocell amplifiers are coupled together through a summing junction to the input of an output amplifier for amplifying the voltage and current signals appearing at the summing junction. Display and/or control means are coupled to the output of the output amplifier.
