Abstract: A method and apparatus for use in ablating hard and soft tissue and in particular, tooth, tooth enamel, tooth dentin, tooth cementum, bone, cartilage, skin, mucosa, gingiva and muscle, and preferably in the oral cavity, is disclosed. In operation, an electromagnetic energy source is applied to a target material producing thermo-elastic failure resulting in fracture or rupture of the material. When this point is reached, the energy source is stopped and immediately a fracturing fluid is applied to the lasing site with sufficient cooling power, solvating power, and momentum to not only cause further fracture or rupture of the material but also to remove debris from the site. The process is repeated until the desired ablation is effected.

Abstract: An apparatus and method for estimating and evaluating acceptability of process variations in a blended meat processing facility. The apparatus implementing the method includes a keyboard, a data storage device, a program storage device, a calculating system and a display device. Information relating to moisture, fat, protein and Added Water are provided to the data storage by an keyboard operator. The calculator in accordance with present functions computes various factors relating to the input data and conducts tests upon the statistical validity of such computations. Providing statistical validity has been maintained, the display device then displays the outputs indicative of the variability of moisture in the blend and in one embodiment is used to control inputs and/or processing steps in the blended meat product to meet preset regulatory requirements.

Abstract: Recording methods, systems and media for recording and read-out with relatively low-power laser means to write digital data "bits" (as reflectance changes) for high density computer storage. One preferred medium comprises a disk support having an "anti-reflective" surface on which is laid a non-continuous "information layer" adapted to absorb recording radiation (from laser beam), and so "write" the bits, by "agglomerating" (coalescing).The information layer exhibits suprisingly high sensitivity, apt for low power recording, and extended archival stability; more suprising, it appears to be formed without any evidence of the usual ablation, "pit formation" or other deformation.
