Abstract: A medication delivery device included molded cylindrical barrel having visual marks on the surface of the barrel in the axial direction, a plunger seals the distal opening of the cylindrical barrel, a molded needle hub disposed in the proximal opening of the cylindrical barrel for sealing the needle hub to the barrel. A needle is disposed in the needle hub for communicating liquids by operation of the plunger in the axial direction.

Abstract: Techniques are disclosed for detecting unidentified inventory in a network. In one embodiment, data that was collected from a plurality of network devices is received. The data includes at least one device identifier for a neighboring network device of at least one network device of the plurality of network devices. The at least one device identifier for the neighboring network device is compared to one or more device identifiers of known network devices. In response to determining that the at least one device identifier for the neighboring network device does not match a device identifier for the known network devices, the at least one device identifier is added to a list of unidentified inventory.

Abstract: A pen needle assembly (701) includes a hub (731) and a metal needle (721) fixedly connected to the hub (731). A cover member (711) removably receives the hub for covering a first end of the needle (721). A sealing member (741) covers a second end of the needle (721). At least one component of the pen needle assembly (701) other than the metal needle (721) is manufactured of a biodegradable polymer, thereby providing a more environmentally friendly pen needle assembly (701) for a drug delivery device (100).

Abstract: A camera mounting apparatus adapted to run through a triangular track members comprising a rectangular base, a rotatable plate pivotably mounted on top of said rectangular base, a tillable plate tiltably secured on said rotatable plate and a pair of spaced apart detachable wheel assemblies (13) securedly supporting said rectangular base and adapted to traverse along said track members.

Abstract: A knockdown-type track wheel system for camera dolly comprising a pair of. spaced apart camera track railings, a plurality of cross-members spacedly supporting said pair of camera track railings, and a collapsible tripod supporting each of said cross-member, each of said cross-member being defined by a pair of opposing threaded studs on the respective ends, a height adjusting means screwably attached to corresponding threaded stud, a ball extending from said height adjusting means, and a triangular railing seat adjustably secured on said ball and fitted to the underside of said camera track railings.

Abstract: A broadband amplifier includes an amplifier device and input and output networks formed of microstrips. The impedance of the output microstrip is chosen by taking the geometric mean of the real parts of one of the scattering parameters of the amplifier device, at the lower and upper limits of the frequency range of interest, and by taking the geometric mean of the system impedance with the result obtained previously. The final result of these calculations is the impedance of the output network. The impedance of the input network is made to be at least twice, and preferably twice, the impedance of the output network. The amplifier is also provided with a slope compensation circuit. It has been discovered that an amplifier designed in this manner exhibits remarkable flatness over a five-octave range. The amplifier circuit is therefore suitable for use in cable television and other broadband telecommunications applications, where the frequency range of interest may be 30 MHz to 1000 MHz.

Abstract: A belt driven infusion pump for emptying the contents of a syringe is disclosed. The pump includes a syringe pusher including an antisiphon catch and a pressure detector which is used for detecting occlusions or the end of infusion. A syringe clamp for locking a syringe in place is also provided. The syringe clamp is spring-loaded and lockable. A syringe position detector is provided to ensure the proper placement of the syringe prior to and during pumping. A control knob is provided on the face of the pump for controlling both the locking of the syringe barrel clamp and the coupling of the drive belt with a d.c. motor. The pump includes a housing having an elongated slot through which the syringe pusher is connected to the drive belt. A sealing band is connected to the syringe pusher and is moveable with the syringe pusher for sealing the slot against moisture or other contaminants.
