Title: Monitoring/control system
Inventor: KIMURA TETSUO
IPC: H04Q9/14
Filed: 1989-03-08
Abstract: A monitoring/control system has a central monitoring/control apparatus (1) and one or more terminal devices (20) connected to the central monitoring/control apparatus (1) through a common transmission line (21), such that the central monitoring/control apparatus (1) can make access to a desired terminal device (20) by address polling. Each terminal device (20) has an address setting device (2) in which an address particular to the terminal device and having a predetermined number of bits is set. The central monitoring/control apparatus (1) is capable of transmitting address data to the terminal devices (20). The number of bits of the address data is variable within a range which does not exceed the number of bits of the particular address set in the address setting device (2). Each terminal device (20) has a coincidence detection circuit (4) which compares the address data with the portion of the particular address having the same number of bits as the address data transmitted from the central monitoring/control apparatus (1), and the terminal device (20) having coincidence is accessed. <IMAGE>

Title: Medical apparatus for producing a heat induced artificial fever (Hiaf)
Inventor: RODRIGUES MICHAEL VICTOR
IPC: A61F7/00
Filed: 1989-06-02
Abstract: The invention relates to an electric/electronic medical apparatus, comprising a user's blood temperature sensoring and controlled electrically heated sleeping envelope for producing a Heat induced Artificial Fever (HIAF) in patients to help overcome a spectrum of viral and bacterial infections that are caused by pathogens which are unable to survive and/or replicate at fever temperatures. The apparatus comprises a lower electric duvet means 1, using a P.T.C. heating element, 1e, fitted on a mattress 13, of a bed 14, and a similar upper electric duvet means 2, between which the patient lies. Both electric duvet means 1, and 2, are connected via an electronic digital control panel 3, to the electricity supply 4. The control panel 3, is connected to a blood temperature measuring intravenous probe 6, inserted in a vein in the patient's arm (alternatively the probe comprises an intimate body cavity probe, or subcutaneous or extracutaneous probe, or a non-contact thermal imaging probe, or a non-contact infra-red detecting/sensing probe). Additional electronic digital displays and controls, and a computer, provided enable the HIAF to be set accurately to specific parameters, selected from a menu of pathogen v/s HIAF parameters known (from HIAF laboratory tests, and other double blind trials) to be effective against specific pathogens. <IMAGE>

Title: Apparatus for driving a solid-state image pickup
Inventor: ARIMORI IWAO
IPC: H04N5/335
Filed: 1989-06-30
Abstract: Apparatus for driving a solid-state image pickup 1 for optimizing the transmission timing of a driving signal to be supplied to the image pickup to thereby adjust the timing of the sample and hold processing 3 of an output signal from the image pickup, employs a shift register 23 for shifting the driving signal to be supplied to the image pickup 1 using a clock signal CLK having a relatively shorter period than the period of the driving signal. The shift register 23 outputs at its plural stages driving signals with different delay times in increments of one period of the clock signal, and a driving signal with a desired delay time is selected SW0-SW7 and supplied to the image pickup, whereby the driving signal can be transmitted with optimum timing.

Title: Improvements relating to pipe closure devices
Inventor: ALDEN PETER
IPC: F16L29/00
Filed: 1990-08-10
Abstract: The pipe closure device is constructed from two main parts namely a support structure 1 and a tubular member 2. The structure is suspended from a cable 3 by means of which it may be lowered into a manhole to enable the tubular member 2 to be introduced into a section of pipeline. The forward end of the tubular member 2 carries a skirt 4 in the form of an expandable tube.

Abstract: A method of producing a laminated structure (6), for example a laminated vehicle windscreen, having two rigid transparent plies (1, 2) whose inner surfaces are adhered together and a holographic area disposed between the two transparent plies (1, 2). In the method a photosensitive recording material (4) is applied to a surface of one of the plies (2) and then the material (4) is exposed to an interference light pattern and a resultant hologram is developed in the material (4). The exposure of the material (4) may be carried out before or after lamination of the structure. The formation of the hologram in the material (4) after the material (4) has been applied to a ply of the ultimate laminate provides the advantage that the optical properties of the hologram can be independent of the ply shape. Preferably, there is an intermediate layer (3) applied to the material (4) before the second ply (1) is laminated thereto. <IMAGE>
