Title: Penetrable cap and fluid transfer device for use therewith
Inventor: ANDERSON BRUCE W
IPC: A61J1/05
Filed: 2000-05-12
Granted: 2009-11-24
Abstract: The present invention relates to a cap which can form an essentially leak-proof seal with a vessel capable of receiving fluid specimens for clinical analysis and diagnosis. To minimize potentially contaminating contact between the fluid specimen and humans or the environment, the present invention features a cap which is penetrable by a plastic pipette tip or other fluid transfer device, and may include a plurality of striations which were discovered to further improve penetrability of the cap. In this way, substances can be dispensed into or withdrawn from the vessel without having to physically separate the cap from the vessel. Also featured are fluid transfer devices having rib structures which aid in improving the penetration and/or strength characteristics of standard fluid transfer devices (e.g., pipettes) and which aid in creating air gaps for venting air from the interior of a collection device to prevent or minimize the release of fluid sample in the form of an aerosol or bubbles.

Abstract: The invention relates to a diversity reception system for motor vehicles for digitally modulated terrestrial and/or satellite radio signals in the frequency range above 1 GHz. The system includes an antenna arrangement of which the reception signal is supplied to a radio receiver. The antenna arrangement is designed as an antenna system having several individual antennas and several antenna components, and contains a controllable logic switching device. The individual antennas and the several antenna components are positioned on the vehicle so that for discrete switching positions of the controllable logic switch, reception signals that are different in terms of diversity are available at the antenna connection point. A reception level testing device is provided for the comparative determination of the reception level contained in the data flow in the HF-channel with an HF channel bandwidth B. The level testing device is designed so that when initiated by the symbol cycle generated in the receiver and during the simultaneously occurring symbol identification of the received flow of data, the reception level is determined in each case within the shortest possible level testing duration.

Abstract: A novel device for analysis and detection of one or more gases or gas components of a gas mixture is disclosed. At least one gas sensor is installed in a capillary tube so that the target gas molecules diffuse through the tube length before affecting the said sensor and the transient response of the device to the target gas is mainly determined by the progress of the said diffusion process. The said transient response is then recorded and used as a measured value so that the target gas detection and diagnosis ensues from its comparison with the results of the previous experiences, calibration tests or mathematical simulations. More elaborate embodiments of the invented device include plurality of capillary tubes, each furnished with its respective gas sensor(s), forming an array or a bundle gas analyzer.

Abstract: A wheelchair is provided which has a seat height adjustment comprised of a double in-line turnbuckle that allows infinite adjustment of the length of a turnbuckle assembly. The assembly includes a handgrip with a longitudinal recess having a first end with smaller internal threads that mate with the external threads of a smaller diameter cylinder. This cylinder can telescope with a recess formed in a second hollow cylinder having oppositely threaded external threads that mote with a second larger diameter set of threads in a second end of the longitudinal recess of the handgrip. The smaller diameter cylinder includes a snap button on a leif spring, which catches an annular shoulder on the recess formed at the transition between the smaller and the larger diameter areas. This inhibits the turnbuckle from over-extension. Further, the assembly has a restraint, which inhibits the turnbuckle assembl y from working out of its selected position during use. The restraint can be p op detent or jam nut. The turnbuckle assembly is pivotally mounted at both ends in brackets, which are fastened respectively to a seat frame member and to a cross frame member.

Granted: 2006-06-13
Abstract: Un circuit de commande de gain qui permet à un circuit d'amplificateur de gain variable de fonctionner  avec une haute linéarité d'entrée et une faible consommation d'énergie. L'amplificateur de gain variable comprend un circuit d'entrée différentiel standard à transistor bipolaire et une paire de transistors de contre-réaction connectés à un transistor de source de courant. Le circuit de commande de gain procure un voltage de commande de contre-réaction variable pour faire varier la résistance effective des transistors de contre-réaction et un voltage variable de polarisation pour faire varier le courant du transistor de source de courant. La linéarité d'entrée de l'amplificateur de gain variable est commandée de manière indépendante du gain en réglant la résistance effective et le courant dans une relation réciproque, de sorte qu'au niveau de gain maximal, le courant est au maximum et la résistance de contre-réaction est au minimum, et au niveau de gain minimal, le courant est au minimum et la résistance de contre-réaction est au maximum. L'amplificateur de gain variable peut donc être réglé pour fonctionner avec une linéarité d'entrée élevée et une faible consommation d'énergie sur des plages de gains faibles.
