Abstract: A system that includes a power transmitting antenna (124) with a coiled conductor defined by a first axis and a second axis perpendicular to the first axis, where a single plane comprises the first axis and the second axis. The system includes a support layer (140, 142) comprising: a substantially planar top surface and a substantially planar bottom surface opposite the substantially planar top surface arranged parallel to the plane. The support layer also comprises a material with a predetermined resiliency. The support layer is configured to support a mass of a user and maintain a predetermined spacing between the plane of the power transmitting antenna and the user during compression of the material from the mass of the user.

Abstract: Three terms (X,Y,"Error") are combined in a single floating-point number in an advanced microprocessor to compute pixel addresses. The floating-point number is reconverted to integer form in multiplexers operating in a mode determined by slope, relative to unity, of the line to be defined by the pixels. The output of the multiplexers is enhanced by a look-up table to produce color data, which are converted to analog form for display. Speed of operation is greatly augmented by the use of floating-point arithmetic to compute the pixel addresses.

Abstract: This method and apparatus are suitable for inclusion in the "graphics circuit board" of a personal computer. The digital output of the computer is used to plot a series of "pixel pairs" which, taken together, closely approximate the desired path of a line to be drawn on a display device such as a color cathode-ray tube. The addresses and relative intensities of the pixels of each pair and of the series are computed so as to produce a line that is substantially free from the "jaggies" resulting from "aliasing" in prior-art apparatus. Computation of addresses relies upon both integer and floating-point numbers.

Abstract: An apparatus and method for use in assisting a human heart is disclosed. A skeletal muscle is formed into a pouch which then surrounds a collapsible, shape-retaining bladder. The bladder is connected to a second bladder enclosed in a sheath around a portion of the aorta. The bladders are filled with a fluid such that when the skeletal muscle contracts in response to an electrical stimulation, the fluid is forced from the first bladder into the bladder sheathed with the aorta, expanding that bladder and forcing the aorta to compress.A period of vascular delay and electrically stimulated training is preferred after the pouch is formed and before use in conjunction with the aorta. Use of a gate means between the two bladders enables implantation of the entire system in one surgical procedure.
