Title: Apparatus and method for converting pictures or images into video signals
Inventor: STUTTLER HERBERT
IPC: G03B27/72
Filed: 1989-10-04
Abstract: ABSTRACT OF THE DISCLOSURE      The invention relates to an apparatus for converting pictures or images into video signals.  A camera (14) is pointed, together with a light source (16), by means of a mirror system (21, 22) at a projection surface (10), which may lie on the apparatus or adjacent to it.  Transmitted light pictures, for examples slides, can be placed in front of the light source (16), the said pictures thus being reproduced on the projection surface (10) and being recorded from there.  Instead of such projected images, it is possible to illuminate and record articles.  Connecting two apparatuses with one another, each apparatus having a monitor (38), provides a universal video telephone.                                                     (Fig. 1)

Inventor: HAINES KENNETH A
IPC: G03H1/16
Filed: 1989-10-16
Abstract: Methods for generating holograms from a computer model of any object employ a combination of numerical and optical means. An illumination model and the light dispersion properties of the object are specified. The hologram is synthesized from a plurality of smaller hologram elements.      Each individual element sustains a field of view of the object. The light rays from the object lying within the field of view and along the lines of sight are sampled by the computer. The sample density should not exceed the resolution limit set by the size of the hologram element . Each light ray is specified by a direction and an amplitude function. The hologram element is obtainable from a Fourier Transform of the sampled rays. In one embodiment, optical means are employed to physically reproduce the sampled light rays using coherent radiation. The reproduced coherent light rays are then interfered with a coherent reference beam to form the hologram element. Alternatively, the interference pattern is calculated directly by the computer and is printed to form the hologram element.

Patent CA-2013202-A1 (CA)
Title: Battery separator with integral thermal fuse
IPC: H01M50/489
Filed: 1990-03-28
Abstract: A battery separator includes a porous substrate and a thermal fuse material adhered to at least one surface of said porous substrate.  The thermal fuse material is adhered to the substrate surface in a predetermined geometric array thereupon so as to establish open areas of the at least one substrate surface to thereby allow ionic migration therethrough.  The thermal fuse material forming the geometric array on the substrate surface may itself define open pores to further facilitate such ionic migration.  The thermal fuse material melts at or near a predetermined threshold temperature so that the substrate's permeability irreversibly becomes significantly decreased and thus interrupts the chemical reaction in an electrochemical battery.  In such a manner, batteries of improved safety may be provided using the separators of this invention.

Title: Method for allocating incoming-call to extension telephone sets in private branch exchange and private branch exchange having automatic incoming-call allocating function
IPC: H04M3/54
Filed: 1990-04-05
Abstract: In an integrated services digital network (ISDN), a caller number indicative of the telephone number of a caller can be usually attached in a call data.  In a private branch exchange according to the present invention,  the caller number of a caller and the extension number or numbers of an extension telephone set or sets to which the call is desired to be directly sent from the caller are previously registered in a suitable memory table in a predetermined correlation, so that when the private branch exchange receives a call from the ISDN,  it retrieves the table to check whether or not the received call  is previously registered in the table in the form of a caller number.          When the call  is registered one,  the call  is preferentially allocated to one or ones of the extension telephone sets having one or ones of the extension numbers associated with the caller number of the received call.   The number registration in the table may be carried out through each of the extension-telephone sets.

Patent CA-2028261-A1 (CA)
IPC: G01N21/359
Filed: 1990-10-22
Abstract: ABSTRACT OF THE INVENTION         A method and apparatus for measuring blood glucose concentration by irraditing blood vessels with electromagnetic radiation using near-infrared radiation diffuse-reflection laser spectroscopy.       This invention uses electromagnetic radiation of  a  wavelength that is transmitted through the skin to the measurement part, for example, a blood vessel.    Since skin is mostly composed of water (H2O), which absorbs IR radiation in nearly the entire IR spectral range, only radiation of a certain, narrow protion of the IR spectral range called the "water transmission window" is transmitted through the skin.      The present invention uses electromagnetic radiation with a wavelength of 1.3µm?1.9µm radiation from a semiconductor diode laser. When electromagnetic radiation of these wavelengths irradiates the skin, light is transmitted through the skin to the blood vessel where the light interacts with the heterogeneous components of the blood.   The light which reaches the blood is then diffusely reflected by the blood.   The reflected light will have been modulated by the characteristic vibrations of the molecules which are major components of blood.    The reflected light is detected and provided as a digital signal to a one-chip microcomputer.   The one-chip microcomputer calculates a blood glucose concentration from the digital signal by reference to a calibration curve stored in the memory of the one-chip microcomputer.       The one-chip microcomputer causes the calculated blood glucose concentration to be displayed on a digital display.

Title: Piston or rod seal
Inventor: WETZEL MICHAEL
IPC: F16J15/3232
Filed: 1990-12-03
Abstract: ABSTRACT        A piston or rod seal includes a first groove in a seal housing, which groove is radially inwardly open towards a relatively movable machine part and receives a rubbing seal ring made of PTFE material and an elastic O-ring of rubber material.  The O-ring is sealed against a groove base of the first groove and forces the rubbing seal ring against the relatively movable machine part.  The rubbing seal ring has, on its side adjacent the relatively movable machine part, at least two sealing ridges which are separated by a second groove and, on its side adjacent the O-ring, a conical. surface.  The second groove has a rounded groove base with a radius, which is substantially equal a radial depth of the second groove.  The conical surface extends across the radial planes of all of the sealing ridges without an appreciable change in direction.  The piston or rod seal has a substantially improved sealing effect for a longer period of use.

Title: Pre-storage filtration of platelets
Inventor: CARMEN RALEIGH A
IPC: A61M1/02
Filed: 1991-02-07
Abstract: Filtration of white blood cells (WBCs) directly from platelet rich plasma (PRP) rather than from subsequently made platelet concentrates (PC).  Earlier filtration is effective at removing most WBCs with minimal platelet loss and permits storage of platelets for at least 5 days.  The filtration is preferably done with a closed, ready-to-use system comprising a WBC filter disposed between a first blood bag and at least two empty secondary bags.  A fourth bag may be included in the closed system to contain a platelet additive solution.  System can remove at least 95% of the WBCs with less than 10% loss in platelets. In very preferred embodiments at least 99.5% of the original WBCs are removed by filtration prior to platelet storage.

Title: Method and apparatus for cursor movement control
Inventor: HIDAKA KAZUYOSHI
IPC: G06F3/0481
Filed: 1991-07-25
Abstract: The constraint mode provided by this invention allows a user to move a cursor of a pointing device, such as a mouse cursor, just along lines and curves on a graphics screen. The user can select a point located on lines and curves correctly even though the pointing device is moved quite roughly.  The user can also select a point that divides a segment by an arbitrary ratio, or a point that divides the segment  into  a  plurality  of  equal  parts.   The  method basically comprises  the  steps  of  entering  a  signal  for pointing to a position on a display screen and determining a point on the display screen in response  to the entered signal.  A point is then determined on the graphics object near to that point determined on the display screen.   A cursor is thus displayed at the determined point on the graphics object.
