  • Physical exercise system using skis
    Patent number: 5184989
    Abstract: A physical exercise system uses conventional downhill or cross-country skis and poles in a skiing exercise system. An ski holder (elevated structure) is attached to the end of each of the pair of skis and a plug is attached to each of the pair of ski poles. The exercise may be performed in the living room environment on a residential carpet.When the skis are moved from a generally horizontal exercising position to a vertical position, for storage or display, the flat base of the ski holder provides for stable upward display and storage of the skis.An exercise method is disclosed which may provide the skier five aerobic points a day in a single twelve-minute exercise period.

  • Telephone line picture transmission
    Patent number: 5175617
    Abstract: A system and method is provided to transmit logmap video images through telephone line band-limited analog channels. The pixel organization in the logmap image is designed to match the sensor geometry of the human eye with a greater concentration of pixels at the center. The transmitter divides the frequency band into channels, and assigns one or two pixels to each channel, for example a 3KHz voice quality telephone line is divided into 768 channels spaced about 3.9Hz apart. Each channel consists of two carrier waves in quadrature, so each channel can carry two pixels. Some channels are reserved for special calibration signals enabling the receiver to detect both the phase and magnitude of the received signal. If the sensor and pixels are connected directly to a bank of oscillators and the receiver can continuously receive each channel, then the receiver need not be synchronized with the transmitter.

  • Parallel processing system having a broadcast, result, and instruction bus for transmitting, receiving and controlling the computation of data
    Patent number: 5163133
    Abstract: A computer system utilizes a parallel data broadcast architecture, called "PDB" is adapted to be connected to a host computer system. In one digital embodiment, the PDB system includes an interface and global memory which is connected to the host computer system and to three common buses. The buses, in parallel, are, respectively, a data broadcast bus, an instruction bus and an output bus, each bus being connected to a plurality of computational units. Each computational unit includes an arithmetic processor, which preferably, in this embodiment, is a digital signal processor (a special-purpose integrated circuit microprocessor), a local memory and a local program memory. The computational units receive the input data simultaneously and in parallel; transform the data, depending on the parameters received from the instruction bus; and communicate their results, by multiplexing, to the output bus.

  • Ultrasonic freeze ablation catheters and probes
    Patent number: 5139496
    Abstract: Probes for medical surgery and flexible catheters for internal tissue ablation in which the tissue cells are frozen and deadened and yet extreme supercooling of tissue below the tissues' melting point is not required. The tissue cells are moderately supercooled by the probe or catheter and freezing of the cells is caused by cavitation nucleation of ice particles within the cells induced by a low power ultrasonic wave generator. The ultrasonic energy causes well distributed nucleation in the supercooled tissue cells and, as a result, the cells rapidly freeze and, due to such freezing, expand and burst their membranes.

  • EEG spatial placement and enhancement method
    Patent number: 5119816
    Abstract: An improved brain wave electroencephalograph (EEG) method measures the physical positions of EEG electrodes applied to the subject's scalp. A set of standard cross-directional lines are obtained to provide measurements of the subject's head and a computer system automatically defines the subject's head shape according to predetermined head shape classes. The position of the electrode on the subject's scalp is then determined by scaling the measurements of the subject's head to a head model of the same head shape class.

  • Method and system in video image reproduction
    Patent number: 5115229
    Abstract: A system and method for the accurate reproduction of the tone and luminance of a first video monitor screen includes, in one embodiment, a first video monitor and a second video monitor, each with a CRT screen. A gray scale test pattern is shown on both screens. The test pattern on each screen is measured using a spot photometer and the results are entered into a computer memory look-up table and compared, a tone-by-tone basis. A set of corrections is obtained for each tone of the gray scale. Those compensating corrections are used to adjust the luminance, on a pixel-by-pixel basis, of the second video screen of the second video monitor, so that the second screen is compensated to produce a gray scale which reproduces the tone and luminance values of the gray scale on the first screen.

  • Magnetic heat pumps using the inverse magnetocaloric effect
    Patent number: 5091361
    Abstract: A heat pump system operates by the inverse magnetocaloric effect in which the working medium is a superconductive body of type II superconductive material having a critical temperature above 23.degree. K. The superconductive body is cooled to below its critical temperature and subjected to a changing magnetic field, which decreases the concentration of paired charged carriers without their complete elimination and induces cooling and/or absorbs heat of the working medium.

  • Tubular welded railing system
    Patent number: 5062732
    Abstract: A railing system is composed of vertically aligned metal tubes and cross-members which are metal tube rails. The posts are formed with round protruding bosses whose outer diameter (OD) is the same as the outer diameter of the posts. The rails also have the same outer diameter. The bosses and rail ends may be brought into roundness, so that they match in a smooth circumferential seam, by round plugs forced into the bosses and rail ends. The post-rail joints are then welded in a circumferential weld.

    Patent number: 5062413
    Abstract: A system for cleaning teeth includes a vacuum motor and a liquid container, each being connected through suction and liquid lines, respectively, to a teeth cleaning head which forms an air tight chamber over two to five teeth. In one embodiment, a one-piece head member has a resilient oval lip which seals against the teeth, a cavity, and a rotatably mounted cleaning roller in the cavity, with the roller being roated by the force of the liquid as the liquid is pulled over the roller by the vacuum. In another embodiment two clamp members, each having a resilient lip, are urged against the front and back faces of adjoining teeth by a spring to form an air-tight chamber on the teeth.

  • Statistical based display for positron emission tomography scans
    Patent number: 5027817
    Abstract: In a medical imaging system a patient is injected with a radiopharmaceutical spontaneously emitting positrons and a PET (Positron Emission Tomography) scan is taken along parallel planes of a portion of the subject's body to produce a slice image composed of pixels arranged in a pattern. The intensity of each pixel is automatically, in a computer system, converted to digital data. The computer system then normalizes the pixels of the slice as to location by calculating the location of each pixel in an ideal or normal slice. The computer system then calculates a Z transform, on a pixel-by-pixel basis, compared to the slices from a normal group to obtain a topographic color-coded map showing the degree of abnormality at each pixel location.

  • Low noise magnetoencephalogram system and method
    Patent number: 5020538
    Abstract: A magnetoencaphalogram (MEG) detects the neuromagnetic brain signals of a subject by bringing a set of magnetic sensors, preferably SQUIDs (superconducting quantum interference device), close to the scalp of the subject. The adverse effect of environmental magnetic noise is reduced by using a second set of magnetic sensors which are placed near the subject. The system includes a bandpass filter, to divide the signals from the various sensors into predetermined frequency bands, and a computer to provide a least squares noise component estimate of the noise from each brain wave sensor and to calculate therefrom a filtered brain wave signal having reduced noise.
