Patent EP-0492056-A2 (EP)
Inventor: HARRELL DURONNIE LEE
IPC: A61L2/24
Filed: 1991-08-26
Abstract: A device for removing air from the steam chamber of an autoclave which includes a sealable sterilization chamber for receiving items to be sterilized. The chamber is sealed and the pressure and temperature therein monitored by sensors. Vapor for sterilizing items is generated in the chamber by a heater. Air is removed from the chamber (pre-conditioning) through a relatively large vent and a selectively activated valve for opening and closing the vent. A digital controller controls the valve, as well as the generation of vapor. The controller receives the monitored temperature and pressure of the chamber as inputs, compares these empirical values with standard values and, on the basis of the comparison, generates a control signal to selectively open or close the valve. In the preferred embodiment, the vapor used is steam and the standard values are a set of coordinates, which when plotted on a pressure/temperature graph, would yield a curve characteristic of saturated steam. The standard values are stored in a memory accessible to the microprocessor. Below a given chamber temperature, venting is discontinued whenever a saturated steam condition is sensed, and above a given chamber temperature, when saturated steam is consistently achieved, the pre-conditioning stage is ended. The entire process of pre-conditioning is controlled by the digital controller, which is preferably a programmed microprocessor. Another aspect of the preferred embodiment is that the time period between successive monitorings of the chamber temperature and pressure is shortened as the temperature in the steam chamber increases.

Abstract: Es wird ein Demultiplexer für ein isochrones Multiplexsignal beschrieben, das aus blockweise verschachtelten isochronen Teilsignalen besteht. Der Multiplexer enthält einen Schreib-Lese-Speicher (MXA, MXB, MXC, MXD) sowie eine Schreib-Lese-Steuerung (ST). Die vorgeschlagene Schaltungsanordnung kann besonders vorteilhaft als integrierte Schaltung ausgeführt werden, weil berücksichtigt worden ist, daß zum Beispiel die Hersteller von Gate Arrays dem Anwender nur die Wahl lassen, in einem Katalog aufgeführte Bausteine zu verwenden. Aus diesen Bausteinen sind die für die Zerlegung eines STM-16-Signals in vier Teilsignale (STM4A, STM4B, STM4C, STM4D) vorgesehenen Funktionsblöcke (MXA bis MXD) aufgebaut. Die Steuersignale für diese Funktionsblöcke (TL15:0, Z(3:0), T311, T622) werden von einer Steuerschaltung (ST) geliefert, deren zentraler Baustein ein vierstufiger, zyklisch laufender Zähler ist. Vom Stand des zyklisch laufenden Zählers werden mit Hilfe von adressierbaren Demultiplexern die benötigten Steuersignale abgeleitet. <IMAGE>

Abstract: Conductive plates (16a - 16e), or floating semiconductor regions (17a - 17d), or conductive plates (16a, 16c, 16e) and floating semiconductor regions (17a, 17d) are disposed in alignment so that a coupling capacitance between the conductive plates and/or the floating semiconductor regions which are adjacent to each other descrease as a distance from a first or second semiconductor region (12, 13) increases. Therefore, the respective potentials at the conductive plates or the floating semiconductor regions can be varied linearly (or at equal potential differences), and corresponding potential distribution can be achieved on the surface of a semiconductor substrate (11). As a result, electric field concentration on the surface of the semiconductor substrate (11) just under a high potential conductive layer (14) can be prevented effectively even by the use of an insulating layer (15) with a common thickness.

Abstract: A microelectronic device (10) provides decreased contact and sheet resistivity for strap (24) and decreased contact resistivity with respect to gate (14) and/or moat (16). The inventive method allows strap (24) to overpass unrelated gate (20) if desired.

Abstract: A fluidized bed combustion method utilizing fine and coarse sorbent feed to control the temperature of a cooling fluid such as water or steam circulating through a fluid flow circuit of a fluidized bed combustor. Fuel particles, such as coal, along with relatively fine and relatively coarse sorbent material, such as limestone, are fed into the furnace section of a fluidized bed reactor. The fuel is combusted, and a fluidizing gas such as air is introduced into the furnace section. Flue gases and entrained material pass from the furnace section, and the entrained material is separated from the flue gases. The separated entrained material passes to a recycle heat exchange section and is cooled before being passed to the furnace section. The recycle heat exchange section is provided with heat exchange surfaces which form part of a fluid flow circuit to transfer heat from the separated entrained material to a cooling fluid such as water or steam which is circulating through the circuit. The ratio of fine to coarse sorbent feed is controlled to control the heat transfer from the separated entrained material in the recycle heat exchange section to the cooling fluid, thereby controlling the temperature of the cooling fluid and enabling the temperature of the cooling fluid to be held constant over a range of fluidized bed reactor loads.

Abstract: A number of bistable magnetic devices (12) are dispersed in a scanning region (13) of a checking object (10). Each bistable magnetic device (12) is formed of a nonmagnetic material which undergoes a drastic flux reversal attributable to the Large Barkhausen effect when subjected in succession to first and second external magnetic fields of opposite directions. A processing apparatus (21) comprises magnetic generators (31, 32) for generating magnetic fields of opposite directions, a transportation mechanism (26) for moving the checking object (10) at constant speed, and a coil (33) for detecting magnetic pulses, which are generated as the bistable magnetic devices (12) are subjected to the flux reversal, as changes of electromagnetic induction voltage. A detection signal for the scanning region (13) detected by the apparatus (21) is converted into a cipher code and then recorded in a code indicator section of the checking object (10). In checking the authenticity of the object (10), the detection signal obtained by scanning the scanning region (13) and a code for collation obtained by decoding the cipher code recorded in the code indicator section are compared, and it is concluded that the checking object (10) is real when the detection signal and the collation code correspond to each other.

Abstract: An input frame to be motion compensated is partitioned into smaller blocks of pixel data. First, motion estimation is performed on each block in the full-pixel resolution. Then, the full-pixel resolution motion vector is refined to half-pixel accuracy by searching the surrounding half-pixel resolution blocks in the vertical and horizontal position with respect to the full-pixel resolution motion vector. An absolute magnitude of a horizontal component of the full-pixel resolution motion vector is examined to see if it is greater or less than a predetermined threshold to detect any significant movement. If the horizontal component absolute magnitude is less than the threshold, a frame-based interpolation will be used for forming the sub-pixel resolution block. If the horizontal component absolute magnitude is greater than the threshold, a field-based interpolation will be used instead. The sub-pixel resolution block is subjected to motion estimation and compensation to obtain a predicted block which will then be coded to obtain a coded bit stream.
