  • Patent number: 5521911
    Abstract: An eyeglass display system utilizes a combination of an eyeglass display member and an eyeglass contacting member. The eyeglass contacting member has an encircling portion adapted to encircle at least a part of the frame of the eyeglasses, and does not interfere with a potential user's view through the lenses when the eyeglasses are tried on. A cantilever support extending from the eyeglass display member supports a plurality of eyeglass contacting members and associated eyeglasses.

  • Patent number: 4998236
    Abstract: Methods and apparatus for writing and reading data provide storage in a volume of memory material consisting of inhomogenously broadened absorption centers such that a beam of electromagnetic radiation controlled to be independently steered and simultaneously shifted in wavelength can access information stored in four independent dimensions, three spatial and one spectral. The memory medium can be utilized to write and read a selectable connection matrix between two completely populated two-dimensional memory planes.

  • Patent number: 4987480
    Abstract: Image encoding apparatus and methods include recursively decomposing the luminance values of sequential frames into spatio-temporal spectral components, by quadrature mirror filter (QMF) processing of the luminance values. The filtered signals are subsampled, and each decomposed level of the spectral components is coded by vector quantization.

  • Patent number: 4973846
    Abstract: Radiation detection methods and apparatus measure ionizing radiation propagating from a radiation source, utilizing a chamber having an electrically conductive sheet, an electrode assembly spaced apart from the conductive sheet and segmented into a plurality of electrically discrete electrode segments, and an ionizable medium disposed between the electrode assembly and conductive sheet, for absorbing the ionizing radiation and generating charged particles in proportion to the radiation energy absorbed. An electrical potential can be provided between the electrode assembly and conductive sheet, so that respective electrode segments collect the charged particles. Elements are provided for comparing the number of charged particles collected on respective electrode segments, to provide a measure of the energy distribution of the ionizing radiation, and for compensating for changes in capacitance or electrical potential between the electrode segments and the electrically conductive sheet elements.

  • Patent number: 4960109
    Abstract: A multi-function probe for use in hyperthermia therapy employs at least one pair of temperature sensors, which may be thermocouples or thermistors. One sensor of the pair includes an exposed electrode which directly measures tissue temperature. The other sensor includes an electrode covered by a material having a known ultrasound absorption coefficient, for measuring the local intensity of ultrasonic energy. By comparing these two measurements, an ultrasound or other hyperthermia energy absorption coefficient of the tissue in the target region can be determined. A plurality of these paired sensors can be utilized to yield a measurement of thermal diffusion. The probe can also include one or more piezoelectric receiver elements, for providing accurate source-to-target registration.

  • Patent number: 4938217
    Abstract: A therapeutic ultrasound hyperthermia system utilizes a phased array of ultrasound transducer elements. By varying the phase delays in the excitation of individual transducer elements, the focal depth of the ultrasonic beam can be varied, without changing the distance between the transducer and the patient. The phased array of transducer elements can be an array of rectangular elements which are rotated about an axis to deliver ultrasound to the target region while minimizing overall heating effect in the treatment areas outside the target region.

  • Patent number: 4938216
    Abstract: A therapeutic hyperthermia system generates a line-focus beam of ultrasound which can be mechanically scanned across a treatment volume of tissue. The ultilization of a line-focus advantageously reduces the peak intensity of the ultrasonic beam. The system includes methods of scanning the line-focus beam to provide optimal treatment protocols for deep tumors and other pathological conditions while minimizing damage in overlying body tissues. The utilization of mechanical scanning reduces the number of transducers, amplifiers and associated electronics required.

  • Patent number: 4893624
    Abstract: A system for delivering ultrasound hyperthermic therapy to a subject includes a plurality of piezoelectric ultrasound transducer elements arranged in a two-dimensional array to provide multiple sources of ultrasonic energy, and variable activation elements for activating the transducer elements individually and at variable electrical energy levels. A plurality of lens elements is provided for transmitting the multiple sources of ultrasonic energy to the subject, in conjunction with focusing elements which individually vary the attitude of the lens elements to change the focal regions of the individual lenses. The transducer elements and lens elements can be corresponding "pie-slice" sectors arranged in a circular array, in combination with a central circular transducer and lens.

  • Patent number: 4379373
    Abstract: A display device formed having a front face and a collapsible easel is provided. The collapsible easel includes a guide panel. A support panel has first and second edges, the first edge of which is hinged to said guide panel. A stay panel is provided, which has first and second edges, the second edge of which is hinged to the display device and the first edge which is hinged to the second edge of said support panel. A guide panel has at least one tongue which rides in a groove formed by a flap hinged to the front face and folded over to lie against the reverse side of the front face. With the tongue riding in the groove the guide means moves from a first position at which the stay panel and support panel are substantially coplanar to a second position at which said support panel and stay panel form an angle to each other. The hinge between said support panel and stay panel and the bottom edge of said front face form two legs to support the display device at a predetermined angle to a surface.

  • Patent number: 4319418
    Abstract: A versatile collapsible ornamental solid having a fully enclosed hollow interior is disclosed. The collapsible ornamental solid is cut from a single sheet of paper or similar material, folded and bonded, and encircled by an elastic band. Additionally, other collapsible ornamental solids having hollow interiors, generally in the shape of spires, are disclosed. These can be bonded to the basic collapsible ornamental solid and the combination collapsed so as to be substantially flat. The collapsible ornamental solids remain in the collapsed state as long as restraining pressure is applied substantially perpendicular to the faces of the collapsed ornamental solids, but automatically deploy by reason of the encircling elastic band when such restraining pressure is removed.
