Latest Patents
F Jack Purchase's latest patents include a guidance system for automated vehicles and a guidance strip for use. The vehicle guidance system is designed to guide vehicles, such as load haul dump vehicles, in underground mines. It utilizes an elongate element, which can take the form of a rope, aligned with the vehicle's path and suspended above it. This element incorporates a fluorescent material that absorbs radiation at one frequency and emits radiation at a second, lower frequency. The vehicle is equipped with a lamp that illuminates the element at the first frequency, such as ultraviolet light, and a camera or detector that captures the second frequency, which may be visible light. The relative positioning of the elongate element and the image from the detector is used to steer the vehicle along the desired path. Additionally, the elongate element can have portions that emit different frequencies in response to the first frequency, providing extra information, such as indications of branch paths.
Another notable patent is a communication system specifically designed for mines. This system features a broadband distribution network with antennas, which may include leaky coax feeders, connected through interface units. These units can adjust signal levels, perform frequency translations, and modify modulation techniques as needed. The system allows for separate inbound and outbound broadband spectra for both the distribution system and the antennas, typically utilizing different frequency bands. This versatile communication system can transmit various types of information, including mobile and fixed radio, LANs, data acquisition systems, and video.
