Patent CA-2107387-A1 (CA)
Inventor: CRICK ANDREW P R
IPC: G06F21/62
Filed: 1993-09-29
Abstract: A computer method and system for allocating memory for a plurality of software routines. Before execution of the software routines, a collective buffer is allocated. Each software routine is assigned an offset within the collective buffer. Each software routine may then use the portion of the collective buffer starting at its offset as its dynamically allocated work space. To allocate the collective buffer, a collective buffer size is first determined which is sufficient to satisfy the total dynamic memory requirements of the software routines. In determining the collective buffer size, the size of a software routine buffer required by each software routine is accumulated into the collective buffer size. As each software routine buffer size requirement is accumulated, the interim total is stored as the offset for the next software routine. When the last software routine buffer size requirement is accumulated, the total indicates the collective buffer size. A collective buffer of the collective buffer size is then allocated. When the software routines are executed, each software routine uses a portion of the collective buffer referenced by its assigned offset. When all the software routines complete execution, the collective buffer may then be deallocated. In a preferred embodiment, the memory is allocated to a software system having a layered architecture including an application program and a device driver comprising a plurality of component device drivers.

Title: Memory Management Method
Inventor: SPEAR DAN
IPC: G06F/
Filed: 1992-07-15
Abstract: A method of increasing the amount of directly addressable memory address locations that can be allocated to RAM. An initialization routine is executed to identify ROM's in reserved memory address space that are to be reallocated. Suitable address space in extended memory is located and the ROM's are mapped into extended  memory address space. A  ROM access interceptor routine is implemented to trap ROM accesses and direct them to the reallocated address space. A ROM access handler routine is implemented to contain the ROM execution and to restore the computer system to a condition where it can continue execution of application or system software after the ROM access is completed. Memory addresses in reserved address space formerly allocated to ROM's can be reallocated to RAM or other memory devices.

Abstract: Abstract of the Disclosure The method for manufacturing heat exchanger elements includes the steps of forming an open tubular base body having a longitudinal extension having a width that is substantially greater than the height thereby defining narrow and wide sides of the tubular base body.   In the longitudinal extension of the tubular base body a longitudinal opening with longitudinal edges remains.   Two strips of sheet metal are removed from a supply roll and corrugated to form corrugated sheet metal strips.    The open tubular  base body and  the corrugated  sheet  metal  strips  are  advance continuously and parallel to one another in the direction of the longitudinal extension through a fastening device such that the wide sides face the corrugated sheet metal strips.   The corrugated sheet metal strips are pressed onto the wide sides and then  fastened to the wide  sides  at  some locations of contact between the wide sides and the   of   corrugated   sheet   metal   strips.          Subsequently,  the  longitudinal  edges  of  the opening are joined to close the opening and form a closed tubular structure.  During fastening of the corrugated sheet metal strips onto the wide sides, the wide sides of the open tubular base body are supported from the interior by a support structure.

Title: Near-range microwave detection for frequency-modulation continuous-wave and stepped frequency radar systems
Inventor: MOTT CHARLES J
IPC: G01S13/931
Filed: 1994-11-17
Abstract: NEAR-RANGE MICROWAVE DETECTION FOR FREQUENCY-MODULATION CONTINUOUS-WAVE AND STEPPED FREQUENCY RADAR SYSTEMS          ABSTRACT A cancellation technique embodied in a system and a radar signal processing method that is employed to detect near-range targets. The present invention uses a frequency-modulation continuous-wave (FMCW) or stepped frequency waveform and is capable of detecting near-range targets that would normally be obscured by transmitter leakage and internal reflections. This cancellation technique works by transmitting one or more reference ramp signals and then subtracting the coherent average of the transmitted reference ramp signals from a group of succeeding transmitted and received ramp return signals. The resulting group of FM ramp return signals is noncoherently integrated to achieve more stable target detection statistics. More particularly, the present technique implements the following processing steps. Generating a predetermined number of reference ramp signals. Coherently averaging target return signals corresponding to transmitted reference ramp signals to produce a reference average signal. Transmitting additional ramp signals. Subtracting the reference average signal from each ramp return signal to produce a cancelled ramp signal. Fourier transforming each cancelled ramp signal. Magnitude detecting theFourier transform signal. Noncoherently integrating the magnitude detected signal. Thresholding the integrated signal. Centroiding the thresholded signal, wherein centroid position is indicative of the range to the nearest target. Displaying target data for a target whose position is less than a predetermined cutoff range.

Title: Process for preparing soft centers in food products
Inventor: WHEELER EDWARD L
IPC: A23L9/20
Filed: 1993-07-28
Abstract: Food products having soft or liquid centers, layers or other areas are formulated by arranging two fat-containing compo-nents contiguous with one another. A fat in the first component migrates into the second, forming a mixture having a lower solids content than the second fat while the structural integrity of the first component is maintained. The process is especially adapted to the formation of soft- and liquid-centered confections. One preferred embodiment employs fats bearing long, saturated C16 to C22 fatty acid residues and a mixture of short C2 to C4 acid residues, preferably containing acetic acid residues, as the mi-grating fat in a confectionery coating, and hydrogenated coconut or palm kernel oil as the fat in the confectionery center. An especially preferred embodiment employs, as the migrating fat, triglycerides bearing long, saturated substituents con-taining at least about 75 % stearic acid residues and short residues derived from acetic acid, a mixture of acetic and propion-ic acid, or a mixture of acetic and butyric acid. Since sucrose and invertase are not essential elements of the center, artificial sweeteners can be used to replace all or part of the sucrose, resulting in reduced calorie confections. Caloric reduction is fur-ther enhanced because preferred migrating fats are low in calories.

Title: System for measuring the distance between two parallel boreholes or wells
Inventor: KUCKES ARTHUR F
IPC: G01V3/26
Filed: 1993-11-04
Abstract: The distance from a borehole (24) to a nearby target well (14) is determined by positioning a magnetic sensor (40) in the borehole (24) at a known depth and providing a magnetic source (50) in the target well (14) and by moving the source (50) to depths above and below the depth of the sensor (40) and detecting maximum field vectors. The distance the source (50) moves between the maxima is the distance between the wells. In another embodiment, the ratio of source magnetic field vectors is used to determine the ratio of the difference in depth z between the source (50) and the sensor (40) to the lateral distance r between the wells. This ratio z/r is then used to determine the separation of the wells.

Abstract: A device is provided for the detection of gas, e.g. air in tubing (14) carrying a liquid. The device includes a transmitter (21) for transmitting a light beam to the liquid contained in the tubing (14), and first and second light receivers (20a, 20b) for receiving reflected and transmitted light emitted from the transmitter (21) and which is incident upon the liquid in the tubing. The light receivers are located within a body member (12) around the liquid conducting tubing and each produces a signal according to the condition of the liquid in the tubing. Both receivers produce such a given signal when gas is present in the liquid but each receiver also produces such a signal under a different liquid condition. A processing means (33) is provided which is responsive to the outputs from the two receivers and indicates that gas is present in the tubing only when both provide said given signal.
