Abstract: An elliptical bicycle comprises a structural frame including two stringers in opposing arcs, one upper and the other lower, a front wheel and a rear wheel driven by a crankset from its support platforms, as well as a steering box formed by fork, steering tube and handlebar. The elliptical bicycle has multiple hinges. The structural frame is provided with a set of main hinges, each applied to a bipartite stringer having an articulation at an approximate angle of up to 170°. A secondary hinge is applied in a bipartite steering tube of the handlebar having an articulation at an approximate angle of up to 180°. A set of tertiary hinges is applied between a crankset and support platforms of the user's feet, each of them having an articulation at an approximate angle of up to 90° upwards.

Abstract: The lid is used to cover a utility box which houses a meter such as a water meter. The lid is compression molded from a plastic material such as medium density polyethylene, and has a planar upper surface and a planar lower surface. In one embodiment, a plurality of generally parallel spaced apart recesses are formed in the lower surface. The recesses are spaced inward of the outer edges of the lid. The area of the lower surface of the lid is greater than the total area of the recesses in the plane of the lower surface. In another embodiment, an opening leading to a cavity is formed in the edge of the lid with a press fit passage for receiving a transponder device.

Abstract: A plunger-less syringe and method of use is disclosed, wherein the syringe includes an outer housing having a size of a standard 3 cc syringe, and fixedly attached to the to the interior of the outer housing is an interior receptacle for receiving a quantity of blood potentially much less than the volume of the outer housing. The novel syringe has a vent at one end that allows air to escape from the receptacle as blood flows therein. Blood can entirely fill the receptacle, fully displacing the air therein so that no unwanted air remains. The vent includes a filter for preventing blood from exiting the interior receptacle at the vent. A vent cap is provided having a recess for mating with a syringe having a plunger for providing an air flow path between the interior of the plunger-type syringe and the interior receptacle of the plunger-less syringe, wherein blood flow into the receptacle can be controlled.

Abstract: The present invention provides for a necktie comprising a wide end with a front side and a back side, a narrow end with a front side and a back side. The necktie has a means for connecting the wide end to the narrow end, and a means for forming a pocket on the back side of the wide end. A method for securing valuables in a pocket attached to the back of a necktie is also provided.
