Abstract: A blood collection device includes a syringe assembly containing a slidable needle assembly within the cavity of a syringe body. The syringe body has a syringe top for receiving a seal assembly wherein the seal assembly is reversibly locked to the top of the syringe top. Within the insertable tube of the seal assembly is an occluding seal secured within the insertable cylinder with retaining rings. The occluding seal allows blood to flow from on end of a double pointed needle into a fully inserted collection tube. When the collection tube is removed the occluding seal keeps blood from flowing into the cavity of the insertable cylinder.

Abstract: An apparatus for holding a gun or a bow securely to an all terrain vehicle. The apparatus has one or more adjustable support arms each having a quick release and lock mechanism. The support arms serve as a way to allow the gun or bow to fit closely to the contour of the vehicle.

Abstract: A dental syringe system having a syringe body containing a needle assembly wherein the syringe body serves as a protective shield after medication is injected. A reusable plunger assembly pushes a slidable seal of a carpule and the needle out for medication delivery and then pulls the needle back within the syringe body after the medication is delivered. The needle assembly, syringe body, carpule carrier and carpule are disposable and the plunger is reusable.

Abstract: An apparatus for providing a step at the back of a pickup truck if the truck has a receiver hitch for holding a receiver bar. The preferred apparatus has a support structure secured to the tongue of the receiver bar with the hitch ball and nut. A pivot plate and a tread plate are pivotally mounted to the support structure, providing the step when in the horizontal position and allowing access to the hitch ball when in the vertical position.

Abstract: A loading apparatus and method for attaching and mounting a loading ramp to a hitch receiver of a pickup truck, van or similar vehicle. A attachment apparatus is comprised of a receiver bar, a support structure, a ramp and a clamping plate for clamping the support structure to the opened tailgate of the pickup truck. The apparatus provides an attachment and also provides for load sharing between the receiver and the tailgate.

Abstract: A communication system is disclosed for providing broadband multimedia services using one or more high-voltage cables of a power distribution network, while the power distribution network is supplying electrical power. A radio-frequency signal at a first location is coupled to the high-voltage cable, transported over the high-voltage cable, and then coupled from the high-voltage cable at a second location. The radio-frequency signal at the first location is modulated with information and demodulated at the second location, thereby providing broadband multimedia service between the two locations. The broadband multimedia communications system may be used for a variety of communication needs, such as telephone service, video service, internet service, and other services requiring high-speed data transfers.

Abstract: A coupling system for transferring a RF signal to and from a high-voltage cable (302) of a power distribution system is described. In one embodiment the coupling system uses a lightning arrester (314) as an element for coupling a RF signal from a RF modem (420) to and from the high-voltage cable. An impedance element of the coupling system is a section of a grounding cable (309) modified with one or more ferrite cores (430) as a means for adjusting the value of the impedance.
