Patent EP-0419039-A2 (EP)
Inventor: ODEN KENNETH W
IPC: G07F5/18
Filed: 1990-08-20
Abstract: A vending apparatus ensures that the delay between a customer's selection of an article, and the dispensation of the selected article, is minimized, preferably to less than a predetermined delay, regardless of the point in a multi-­article vending cycle. The reduced selection-dispensation delay is achieved through use of a "memory and learning" feature. The "memory and learning" feature is predicated on a recall and/or analysis of the relative times of occurrence of one or more previous dispensations, so that the apparatus' present position in the multi-article vending cycle is determined. The "memory and learning" feature allows the vending apparatus to anticipate how long the article dispensation mechanism should run after the present dispensation, to strategically poise the mechanism for a subsequent dispensation having an optimum selection-­dispensation delay. Also disclosed are systems and methods for ensuring that articles are dispensed at a proper temperature, even after a "sold-out" condition is corrected; and for sounding an alarm if a person jars the vending apparatus in an attempt to improperly jar an article from the vending apparatus.

Abstract: In a liquid crystal display (50), the optical transmission of the liquid crystal medium as a function of applied electric field varies with temperature. In order to ensure that the temperature of the liquid crystal medium can provide a practical response time, a heating element (51) along with a temperature sensor (52) and a thermostat (53) establishes the temperature of the LCD in an appropriate range. The output signal of the sensor is digitized and is used as a first portion of a memory unit address. A second portion of the memory unit address is provided by digital command signals either from an operator or from the processing apparatus controlling the image of the LCD. The logic signals stored at the location determined by the first and second address portions identify an electric energizing voltage for the LCD that provides compensation for temperature and for non-linear characteristics of the liquid crystal medium. The logic signals from the memory (55) are converted into a voltage to be applied to the liquid crystal display (50)(Fig.5)..

Abstract: A computer for simultaneously executing plural instructions. A decision means determines the types of operation and the possibility of simultaneous execution for the plural instructions when they are read out from the main memory (1) to the cache memory (3). The result of this determination is called a decision result. The plural instructions and decision result are stored in the cache memory (3). The decision process is performed for several subsets of the plural instructions read out from the main memory (1) to the cache memory (3) in order. 
     Then, the plural instructions are respectively assigned to corresponding operation units according to the decision result and executed. As a result of this arrangement, the repeated decision process for the plural instructions need not be repeated each time the instructions are read out from the cache memory (3) to the operation unit.

Abstract: A shoe and shoe sole for accommodating forefoot strike activities such as aerobics, and forefoot strike tendencies of runners and the like, to forestall stress features, tendonitis and muscle tears, incorporates a forefoot pad (18) in the midsole (16). The pad has a forward chamber (18a) and a rearward chamber (18b), separated by an internal wall (18c,18c′) with restricted orifices therein, the forward chamber being larger and extending curvilinearly beneath the five metatarsal heads of the foot, and the rearward chamber being smaller and extending behind the second, third and fourth metatarsal heads in the arch region of the foot. Impact compression by the metatarsal heads on the forward chamber causes controlled viscous liquid flow into the rearward chamber to absorb impact force, and such that the amount of liquid in the rearward chamber is temporarily greater than its at rest volume, causing the walls of that chamber to bulge and form a temporary arch support. Release of force on the forward chamber results in the resilient flexible bulging walls of the rearward chamber forcing liquid back to the forward chamber.

Abstract: The invention provides increased surface contact area for circuit board heat removal, without exposing the circuit board components to the coolant fluid. This is accomplished by compressing a heat conductive flexible membrane between adjacent circuit boards. The flexible membrane contains coolant fluid which is pumped into and out of the flexible membrane. The membrane isolates the circuit card components from the coolant fluid and is flexible enough so that it conforms to the surface of individual circuit boards. A plurality of coolant membranes are sandwiched between adjacent boards and housed such that the combination of fluid pressure and board to board spacing maintain the conformity of the membrane to the circuit board surface. Individual boards within the housing are electrically connected with edge connectors on all four sides and are separately removable from the housing. Fluid flow to coolant membranes is maintained through the edges of the membranes and between the boards at the four corners of the boards. This lamination of cooling membranes between circuit boards, each with their individual edge electrical connections and cooling connections, allows efficient packaging of the electrical components on the circuit boards.

Abstract: The invention relates to an input buffer (16) of an integrated circuit having a PMOS transistor (P1) and an NMOS transistor (N1) connected in series between first and second reference voltage terminals (V DD , V SS ). A first filter (26) comprising a capacitor (C1) and a resistor (R1) is coupled between an input terminal (18), the first reference voltage terminal (V DD ) and the control electrode of the PMOS transistor (P1), and a second filter (28) comprising a capacitor (C2) and a resistor (R2) is coupled between the input terminal (18), the second reference voltage terminal (V SS ) and the control electrode of the NMOS transistor (N1). The filters (26, 28) act as low pass filters between the input terminal (18) and the control electrodes of the PMOS and NMOS transistors (P1, N1), and act as high pass filters between the reference voltage terminals (V DD , V SS ) and the control electrodes. By virtue of the filters (26, 28), the input buffer (16) has reduced sensitivity to voltage transients on the reference voltage terminals (V DD , V SS ).

Abstract: An improved method and apparatus for making solder connections from input/output connecting pins (2) to the circuitry (4) on a pinned metallized ceramic substrate (1). A solder preform in the shape of a sphere provides the correct volume of solder. These spheres are held in position at each desired joint by a templet. The substrate, solder sphere and templet assembly is passed through a furnace in a reducing atmosphere and at a temperature to facilitate solder reflow and wetting, thus creating a sound mechanical and electrical connection between the pin and its portion of the circuitry. The method and apparatus of the invention provides joints have a high degree of reliability such that all connections are made to acceptable soldering standards, none lacking integrity. Only harmless by-products are produced in the practice of the invention, and no residue is produced which requires cleaning by means of chemical solvents and therefore is environmentally superior.
