Abstract: A light and bioelectric therapy pad that delivers light and bioelectric stimulation to adjacent tissue. The therapy pad includes an electrical tracing circuit containing elongated, parallel and spaced-apart approximate linear tracings (ALT) that provide current flow in opposite directions along the ALT during alternating positive and negative drive cycles of an alternating current (AC) supply. The ALT includes first and second header tracings wired to a row of light emitting diodes (LEDs), with the anodes of a first group of LEDs wired to the first header tracing, and the anodes of the remaining LEDs wired to the second header tracing. The ALTs are wired into the circuit with current flowing to the first header tracing at one end of the row of LEDs, and to the second header tracing at the opposite end, so that adjacent ALT provide current flow in opposite directions during both positive and negative drive cycles.

Abstract: A liquid sample is placed into a sample container which is placed into an optical fourier transform system to produce an image representative of characteristics of the liquid sample and particles within the liquid sample. The container, formed of an optical material, includes microchannels which continuously increase in path length from a minimum path length at a first side to a maximum path length at a second side. In one embodiment, the microchannels are immediately adjacent one another while in another embodiment the microchannels are spaced from one another by a defined spacing. By spacing the microchannels from one another, two fourier transform images are generated within the system, one a refracted image and the other a diffracted image. In addition, by forming the second sides of the spaced microchannels at an acute angle relative to the plane of the microchannels, a reflected fourier transform image can also be generated within the system.

Abstract: In vivo irradiation of blood is performed via catheters which can also or alternately be used to introduce fluids into blood vessels. The catheters include narrow tubular portions which are at least partially inserted into blood vessels. The narrow tubular portions utilize optical material to carry light radiation into blood vessels for irradiation of blood therein. In some embodiments, the tubular portions of the catheters are made of optical material to directly carry light radiation. The tubular portions are then made to diffuse the light along at least a portion of their lengths or to carry light to diffusing and preferably radio-opaque tips from which the majority of the light is diffused.

Abstract: An optical fourier transform image representative of characteristics of a liquid sample and particles within the fluid sample is quickly and inexpensively generated by an optical fourier transform system. A small liquid sample is received in a lenticular array liquid sample container with the fluid sample entering open-ended microchannels in the container preferably by capillary action. The container is formed of an optical material such that the fluid sample in the microchannels forms a grating when placed into an optical fourier transform system. Accordingly, the fourier transform image generated within the system is characteristic of the liquid sample forming the grating for the system. The liquid sample container is formed of two plates of optical acrylic, which may be coated or otherwise treated to make it non-hydrophobic to prevent the loss of moisture from liquid samples. A first one of the plates has an array of microgrooves formed into a first surface of the plate.
