Abstract: An arrow construction system comprising a tip canister configured to receive an arrow tip and to attach to an arrow shaft. The tip canister contains a power source and sensitive electronics. The power circuit may be a battery, a primary storage capacitor, a coil and a rectifier, and/or a solar cell. The tip canister may be electrically connected to the nock via the shaft electrical conduction system. The electrical conductors may be integrated into the shaft. The wires may form a cable with standard connectors. The nock may contain a light. Alternatively, the fletching may comprise light emitting film or fibers. The circuits may include a flash circuit, an audio circuit, a radio beacon, a wireless transmitter, environmental sensors, a camera, a switch, and/or a GPS device. The switch may be activated by a current detected in a coil or by an accelerometer.

Abstract: A leg strap with preferably horizontal handles attached at each end of each handle, is used to aid in lifting a jumping player, especially for lineouts in Rugby Union. The handles are preferably made of elastic bands with contract to provide a tight fit on the leg of the jumper and when jumping allow for secure grasp by lifters. The simple, reusable, easy to use leg straps provide a level of effectiveness, comfort, convenience, and safety not provided by conventional methods. To use, leg straps are applied to one or more legs of a jumper. When the jumper jumps, one or more lifters grip the leg device. The lifters lift the jumper higher, support the jumper in the jump while the jumper attempts to intercept a ball, and safely lower the jumper.

Abstract: Methods, medium, and machines which compress, enhance, encode, transmit, decode, decompress and display digital video images. Real time compression is achieved by sub-sampling each frame of a video signal, filtering the pixel values, and encoding. Real time transmission is achieved due to high levels of effective compression. Real time decompression is achieved by decoding and decompressing the encoded data to display high quality images. A receiver can alter various setting including, but not limited to, the format for the compression, image size, frame rate, brightness and contrast. In a Doppler improvement aspect of the invention, Doppler velocity scales are incorporated into grayscale compression methods using two bits. Variable formats may be selected and Doppler encoding can be turned on and off based on the image content.

Abstract: An easy to use, universal, simple, lightweight, compact, portable and modular system of concealment and shelter. An operator can configure a number of concealment blinds or shelters using brackets, supports, segmented shafts, covers, curtains, and skirts, and more complex modules. The segmented shafts have both the ability to make an attachment to retain a particular configuration while being able to break down the shafts for transportation or storage. The brackets and supports can be used to secure a configuration to a tree, the ground, or a hand held device. More advanced modules include cover caps including domes, cylindrical arches, and pyramids. A configuration can include a removable floor. Guyline modules allow for sliding panels to be positioned over openings in a configuration. The system can be configured for placement on a hillside or over rough terrain and obstacles.

Abstract: A method of and system for transmitting video images preferably allows a specially trained individual to remotely supervise, instruct, and observe administration of medical tests conducted at remote locations. This system preferably includes a source device, a transmitting device, and at least one remote receiving device. The transmitting device, and the remote receiving device communicate over a network such as any appropriate data network. The transmitting device transmits the video images to the remote receiving device either for live display from the source device or for pre-recorded display from a video recorder device. The remote receiving device is also capable of communicating with the transmitting device while simultaneously receiving video images to provide remote control. The source device is preferably a medical test device such as an ultrasound, a sonogram, an echocardiogram, an angioplastigram, and the like.

Abstract: An easy to use, universal, simple, lightweight compact, portable, dynamically configurable and modular system of concealment and shelter. An operator configures a number of concealment blinds or shelters using brackets, support, segmented and telescoping shafts, covers, curtains, and skirts, and more complex modules. The brackets and supports are used to secure a configuration to a tree or the ground. Advanced modules included user adjustable domes and cylindrical arches. The system can be configured for placement on a hillside or over rough terrain and obstacles, or four different types use. The system provides covers with novel windows, movable panels, and configuration attachments. The operator changes the configuration of the structure to quickly provide cover, to increase cover, and to adapt to terrain or changing weather. The system includes novel methods of tightening the skin on a cover to reduce movement and noises.

Abstract: A leg device with means for gripping, or handles, is used to aid in lifting a jumping player, especially for lineouts in Rugby Union. The simple, reusable, easy to use leg device provides a level of effectiveness, comfort, convenience, and safety not provided by conventional methods. In a leg sleeve embodiment, means for gripping include a thickened band or grip attached to a sleeve material. The means for gripping may be formed by attaching a semi-rigid material. The means for gripping may be formed by attaching extra layers in sections, in rolls, in folds. The means for gripping may be shaped to match the hand of a lifter. The means for gripping may comprise memory foam. The leg sleeve may further comprise a knee cutout or a hamstring cutout. To use, leg sleeves are applied to the legs of a jumper. Other embodiments of leg devices include leg glove or mitt and various leg straps. When the jumper jumps, one or more lifters grip the leg device.
