A steering apparatus for altering steering direction of an exercise bicycle utilizing an interactive computer or television video game simulation which consists of a steering mechanism primary frame (22) that includes a steering tube (24) and a steering plate (26). The steering tube is disposed within an exercise bicycle frame head. A steer frame (58) is rotatably mounted within the primary frame and utilizes a pair of springs (60) that are suspended between the primary frame and the steer frame. Changing steering direction by rotation of the handlebar (70) attached to the steer frame creates progressively linear resistance to the handlebar movement. The steer frame returns to a centered position when unrestrained, duplicating the feel and impression of riding a bicycle. A potentiometer (32) interfaces with the rotating steer frame providing variable electrical resistance relative to the directional movement of the steer frame to the primary frame. An electrical signal is transmitted from an interactive computer or television video game to the potentiometer which interprets the actual steering position of the exercise bicycle.

A waterfowl luring system provides directional motion to one or more waterfowl decoys. The system employs a motor or other force-generating device to rotate a platform to which one or more decoys are attached so that the decoys are moved in relation to rotation of the platform. In operation, the decoys are moved along a substantially circular flight path. The system is highly versatile and may be employed on dry land or in shallow as well as deep water environments.

The invention described is a bicycle handlebar mounted map holder constructed from folded aluminum sheet with an external bracket to prevent flex of the map holder when riding over rough terrain. The map holder is intended for use in adventure racing or bicycle orienteering to enable the competitor to read the map while keeping both hands on the handlebars.

A system and method for detecting the railway vehicle with a plurality of RFID readers and tags are disclosed. Railway vehicle directional movement on specific track can be detected and updated by the RF communication of the readers and tags. The railway system also includes a computer which monitors a couple of RFID readers for the real-time railway vehicle position. Intelligent detection algorithm is implemented in the reader to identify specific railway vehicle, on a particular track for at least one track in bidirectional or parallel direction. For encoding the data, each RF tag is of unique ID and the RF signal is encrypted.

A system and method of identifying a position of a crop row in a field, where an image of two or more crop rows is transmitted to a vision data processor. The vision data processor defines a candidate scan line profile for a corresponding heading and pitch associated with a directional movement of a vehicle, for example, traversing the two or more crop rows. The candidate scan line profile comprises an array of vector quantities, where each vector quantity comprises an intensity value and a corresponding position datum. A preferential scan line profile in a search space about the candidate scan line profile is determined, and the candidate scan line profile is identified as a preferential scan line profile for estimating a position (e.g., peak variation) of one or more crop rows if a variation in the intensity level of the candidate scan line profile exceeds a threshold variation value. In addition, a template scan line profile may be utilized, where a candidate scan line profile is identified to be a preferential scan line profile if it is consistent with the template scan line profile.

The invention discloses an extraction method and application of high-activity collagen, and belongs to the fields of biotechnology and cosmetics. The collagen is extracted by adopting a combined extraction method, so that the extraction time is shortened, the extraction rate is improved, the purity is improved, the environmental pollution is avoided, and the natural biological character of the collagen is maintained to the maximum degree. On that basis, the invention further provides a fishskin collagen anti-wrinkle essence. The adjustment of skin cutin can be helped, the cutin is smooth, theskin is whitened in an orienteering manner, the activity of face cells is stimulated, darkness is decomposed in multiple layers, the essence is antioxidant, the skin color is balanced, and damaged cells caused by ultraviolet rays or other cosmetics are repaired.
