Abstract: A thrombectomy device includes a tubular shunt generally connected at an upstream end to a relatively high-pressure blood vessel such as an artery and at a downstream end to a relatively low-pressure blood vessel such as a vein. During use, the shunt is disposed mostly outside of the patient. A filter is disposed in the shunt for blocking the passage of clot particles. This device enables a real-time return of blood to the vascular system of the patient. A selectively operable syringe is operatively connected to the tubular member for exerting an auxiliary force on clot material stuck in one of the tubular member and the inlet port element. A three-way valve element is operable in first configuration to couple the suction device to the inlet port element, in a second configuration to couple the suction device to the outlet port element, and in a third configuration to couple the inlet port element and the outlet port element to one another.

Abstract: A golf park including a golf course having a single fairway with multiple greens. At least two greens are provided, at opposite ends of the fairway. One or more additional greens may be provided between the first two greens and along the fairway. Also, multiple tees are provided for the one fairway. At least one tee is provided at each end of the fairway, the tee facing down the fairway towards the green at the opposite end of the fairway. Each green may be the target of two or more tees disposed at different locations on the fairway. The golf course is occupied for a predetermined limited period of time by an individual or a single group of golfers. The individual or single group of golfers plays back and forth along the fairway, for as long as they have reserved the course. They can play at their own pace, undisturbed by other golfers because there are no other golfers on the course. The only limitation is duration: eventually they will have to stop because their reserved interval of play has terminated.

Abstract: In a method for detecting objects hidden underground, a plurality of electromechanical transducers including at least one electroacoustic pressure wave generator and at least one acoustoelectric sensor are disposed above a ground structure. Locations of the transducers relative to one another are determined. The pressure wave generator is energized to produce an outgoing pressure wave which is transmitted into the ground structure. Incoming pressure waves reflected by underground surfaces in response to the outgoing pressure wave are sensed and analyzed to determine three-dimensional shapes of underground objects disposed in the ground structure.

Abstract: A system for underground surveying includes a plurality of substantially rigid frames and a plurality of acoustoelectric sensors for generating electrical signals encoding echo responses of underground surfaces. Each of the frames carries at least one of the sensors, the sensors being disposable in effective physical contact with underground structures upon an insertion of the frames through a ground surface. An acoustic energy generator is disposed on at least one of the frames, while position determination componentry is operatively connected to the sensors for determining locations of the sensors relative to one another. An electronic signal processor is operatively connected to the sensors for analyzing the electrical signals in accordance with the determined locations of the sensors to determine surfaces of an object hidden underground and for generating a video signal encoding an image of the object. A video monitor is operatively connected to the processor for displaying the image of the object.

Abstract: Puzzles characterized by one or a number of sets of visually identical, physically interchangeable, rotatable pieces that either contain magnets with varying north/south orientations embedded in their sides and/or have a mark or markings on one or more of their edges and computer versions of these puzzles. The object of the puzzles is to arrange the pieces in predetermined shapes and sequences in such a manner that the sides of the pieces which are in contact with the sides of other pieces have opposite magnetic poles facing each other so that the pieces attract, rather than repel or, if edge markings are used with or instead of magnets, so that adjacent edge markings comply with specified rules. In addition, the pieces may be all visually identical except for differences in edge markings, if any, or, alternatively, there may be several sets of visually identical pieces, e.g., pink pieces, blue pieces, yellow pieces and orange pieces, which together comprise a puzzle set.

Abstract: The present invention relates to the discovery that certain .beta.-L-dioxolane nucleoside analogs which contain a uracil base, and preferably, a 5-halosubstituted uracil base, exhibit unexpectedly high activity against Epstein-Barr virus (EBV), Varciella-Zoster virus (VZV) and Herpes Virus 8 (HV-8). In particular, the compounds according to the present invention show potent inhibition of the replication of the virus (viral growth) in combination with very low toxicity to the host cells (i.e., animal or human tissue). Compounds are useful for treating EBV, VZV and HV-8 infections in humans.
