Patent GB-2270384-A (GB)
Title: A variable frequency oscillator system with ratio conversion properties
Inventor: WILLIS JOHN
IPC: G01D5/243
Filed: 1992-09-04
Abstract: The system converts an impedance circuit unbalance to a difference of two frequencies and thus, if desired, to a mark-to-space ratio. As shown the sinusoidal output from an oscillator circuit comprising an amplifier A1 with positive feedback is used to excite a bridge network B. The signal produced by any bridge unbalance is fed back in phase or antiphase with the oscillator output signal so as to vary the apparent reactance of the inductor Land capacitor C which determine the frequency of oscillation, thereby altering the frequency. Each time an integral number of cycles of oscillation have been completed, a change-over switching circuit S reverses between its position 1, in which L and C are unmodified, and position 2 in which a bridge unbalance voltage is fed to L and C to alter their effective values. The oscillation frequency thus alternates between two corresponding values. A circuit is described (Fig. 5 not shown) which generates a mark-to-space ratio which is directly related to, and is therefore a measure of, bridge unbalance. The oscillator system may thus effectively convert an impedance ratio to a time ratio. Simple analogue or digital circuits which measure the mark and space periods provide a readout of bridge unbalance. <IMAGE>

Patent GB-2290400-A (GB)
Title: Visual communications apparatus
Inventor: KAHN DAVID ALEXANDER
IPC: G06F3/023
Filed: 1995-06-16
Abstract: In an eye-directed communications device which displays characters and determines a user's selection by monitoring eye position to determine which of the characters is being observed, the usual characters and functions of a conventional 101 key computer keyboard are divided into three sets, designated as lower case, upper case and "command" case. The user first selects the case and then selects the character. Only one set need be displayed to the user, the characters in the other sets having spatial correspondence with those in the displayed set. The system may also, or alternatively, display the characters in groups and define position selection fields corresponding to the positions of the characters in each group. The user then determines the position of the desired character in its group and makes a character selection by first selecting the corresponding position field. The apparatus then limits subsequent character selection by the user to the subset of characters in the corresponding positions in their groups, which allows detection to use a larger area. A head-mounted pointer or hand-held optical pointer may be used instead. <IMAGE>

Abstract: A vertical cabinet (10) that has the dual function of transferring heat or cold to food articles within that cabinet (10). The cabinet comprises a plurality of vertically spaced-apart support shelves of a conductive material for supporting food articles. One aspect of the invention provides for an energy circulation element placed at the upper end of the cabinet for circulating energy through the shelves, and particularly through a serpentine shape thermalizing means or power channel enclosed entirely within the shelf. Inlet and outlet connectors provide for entry of the energy into and out of the shelves. Supply conduits are provided within the cabinet for transferring the energy from the energy circulation element to the thermalizing means. Return conduits within the cabinet facilitate return of the energy to the energy circulation element. Another aspect of the invention provides for a refrigeration/cooling assembly means connected to the cabinet. The cooling assembly comprises a heating/cooling selector attachment unit attached directly to the back manifold of the apparatus and a refrigeration/cooling unit (180) connected to the attachment unit. A chilled fluid transfer media flows from the cooling unit to the attachment unit to circulate through the shelves of the cabinet and then return to the cooling unit for recooling. The cooling assembly achieves the more efficient conduction cooling of food articles in the cabinet rather than the less efficient conventional convection cooling. <IMAGE>
