Abstract: An electronic agility training system, including an array of multilayer, flexible footfall portions, a microprocessor operationally connected footfall portions, a user interface connected to the microprocessor, a pressure sensor positioned in each respective footfall portion and connected to the microprocessor, and a light source positioned in each respective footfall portion and operationally connected to the microprocessor. The microprocessor is programmed to receive user information and to sequentially light respective footfall portions in one of a plurality of predetermined patterns and speeds. Actuation of the pressure sensor positioned in a lit footfall portion generates a first signal to the microprocessor, while actuation of the pressure sensor positioned in an unlit footfall portion generates a second signal. Likewise, a null activation of the pressure sensor positioned in a lit footfall portion generates a second signal to the microprocessor.

Abstract: An assembly for providing illumination to an automobile wheel having an at least partially transparent wheel covering. The assembly includes a bracket nondestructively secured to a non-rotating portion of an automobile wheel, a light emitting array connected to the bracket, and a power source electrically connected to the light emitting array. The light emitting array is positioned to intermittently shine light through the at least partially transparent wheel covering. The bracket is adjustably positionable relative the non-rotating portion of the wheel.

Abstract: An assembly for providing illumination to an automobile wheel having an at least partially transparent wheel covering. The assembly includes a bracket for securing to the a non-rotating portion of an automobile wheel and a light emitting diode or diode array operationally connected to the bracket. A rechargeable battery is electrically connected to the light emitting diode and the light emitting diode, when energized, shines light through the at least partially transparent wheel covering when the wheel covering is rotating.

Abstract: The present invention relates to a self-contained optical repeater that detects light of a first frequency (color) and emits light at a different frequency (color) with intensity related to the incident light flux of the detected light of the first frequency. The emitted light of the second frequency (i.e., the excitation light) is used to fluoresce an optical sample to emit the detected light of the second frequency (i.e., the fluoresced light). The frequency (and energy) of the excitation light greater than the frequency (and energy) of the fluoresced light. The excitation light is filtered and detected by a photodiode. Output of the excitation light is electronically controlled to be a predetermined fraction of the incident fluorescent illumination as filtered and presented to the electronic control circuit in a geometry that mimics a specific fluorescent chemistry.

Abstract: The instrument includes a cartridge carousel assembly which receives analytical cartridges. The cartridges are self-contained units which incorporate a sample metering/separation system which is operated by centrifugal force. The cartridge carousel is composed of a cartridge rotor plate which includes a center and a plurality of cartridge ports which are located in spaced relation radially outward from the center of the plate. The cartridge ports include a cartridge dock which is shaped to receive the cartridges and a balance weight dock which is located radially inward from the cartridge dock. The cartridge dock is shaped to receive a balance weight. A locking mechanism is provided which holds the cartridge in the cartridge dock during rotation of the cartridge rotor plate. A balancing mechanism is provided which includes a balance weight which is movable to the balance weight dock when a cartridge is inserted into the cartridge dock.

Abstract: An optical system for measuring the reflectance of flat strips having potentially optically non-uniform surfaces. In one embodiment the systems includes an array of discrete light sources, wherein each light source is driven by its own individual current, such that the pattern reflected onto a photodector is substantially uniform in intensity.
