Patent CA-2146055-A1 (CA)
Title: Building constructions using beams and related method
Inventor: CORSTON CHARLES
IPC: E04B1/00
Filed: 1995-03-31
Abstract: A floor, wall, roof, or ceiling of a building is made of specially adapted beams and overlying panels. The beams have a layer of foam material on their edges. The foam material can include a resiliently compressible material, a thermally insulating material, or a material which possesses both of these properties. The panels are positioned over the beams so that the foam material is sandwiched between the beams and the panels.      When the panels are fastened to the beams, the resiliently compressible foam material partially compresses, thereby filling any gaps which may form between the beams and the panels. The resiliently compressible foam material thus prevents relative movement between the panel and the beams which would otherwise produce squeaks. When the foam material includes thermal insulating material, it forms a thermal barrier between panels and beams, especially metal beams, thereby eliminating various drawbacks of construction using metal beams.

Title: Optimal parallel processor architecture for real-time multitasking
Inventor: KARTALOPOULOS STAMATIOS VASILI
IPC: G06F9/45
Filed: 1995-04-24
Abstract: A process for producing a parallel processor system having the minimum number of microprocessors necessary execute in real time a set of tasks of a multi-tasking application such that execution of an activity of a first task is followed by execution of an activity of a second task.  The process includes the step of selecting an initial number of microprocessors for executing the application in real-time.  The selecting step includes placing in a first column of a matrix all real-time constrained tasks specific to the application and associating a row of dependent tasks with each task placed in the first column of the matrix to define a plurality of task subsets, each subset incorporating a maximum number of intradependent tasks  and a minimum number of interdependent tasks and the number of subsets corresponding to the initial number of microprocessors. The inventive process further includes the steps of listing dependencies between rows in a second column of the matrix, assigning a priority pi to each task where pi is between 0 and 1, subdividing at least one of the tasks into discrete activities, each of the activities having a corresponding execution time tij, estimating the execution time for each activity, reducing the number of rows in the matrix by grouping together tasks having activities that can be executed within a predetermined time window T, and providing a number of microprocessors corresponding to the number of rows obtained from the rows reducing step.

Patent CA-2160525-A1 (CA)
Inventor: RAMSEY JENS K
IPC: G06F1/32
Filed: 1995-10-13
Abstract: A circuit for placing an external or L2 cache memory into low power mode in response to certain special cycles executed by the microprocessor.  In particular, the special cycles are the stop grant acknowledge special cycle and the halt special cycle. The microprocessor executes the stop grant acknowledge special cycle in response to a request by the computer system to slow down its clock.  This request is asserted by the computer system if the system has been idle for a predetermined period of time.  The halt special cycle is generated by the microprocessor when a HALT instruction is executed.  The stop grant acknowledge and halt special cycles place the microprocessor into a low power state.  Since the microprocessor is in low power mode, the L2 cache memory is also placed into low power mode for further power conservation.  The L2 cache memory is implemented either with synchronous or asynchronous static random access memories (SRAMs).  To place a synchronous SRAM into low power mode, its address strobe input is asserted while its chip select input is deasserted. For an asynchronous SRAM, deasserting its chip select input causes the SRAM to transition into low power mode.

Title: Sport and recreational water bottle cap possessing a housing apparatus designed to accommodate and operate a replaceable filter insert cartridge
Inventor: COLLETTE DANIEL JOSEPH
IPC: C02F1/00
Filed: 1996-05-14
Abstract: A sport and recreational water bottle, which has a water filtering device, removes impurities from various drinking water sources (ie: tap water, lakes, etc...). In a sport or recreational water bottle containing a water filtering device the configuration and composition of the filtering material may vary according to the purification requirements. In the sport and recreational water bottle cap possessing a housing apparatus designed to accommodate and operate a replaceable insert filter cartridge ( hereafter referred to as the cap), the configuration and composition of the filtering material, which would vary according to desired purification needs or requirements, forms no specific part of this invention. The cap is specifically designed to house and operate an insert filter cartridge that is capable of housing filtering material. The design of the cap allows the conventional sport and recreational water bottle to retain its original aesthetic and operational qualities while providing the user with the added feature of filtering water during use. The cap will attach to any water bottle that is compatible in size and fastener, which is all encompassing when a fastening adapter is used.

Abstract: The present invention relates to a battery charging unit. A battery charging unit is provided with a charge controlling unit which is designed to perform at least one of a rest mode operating function which stops charging for respective battery groups. A discharge mode is also provided which discharges electric power from the respective battery groups.  In addition a charge mode is provided for the respective battery groups.  The battery charging unit controls charging for the respective battery groups through the charge controlling unit while repeating at least two modes including the charging mode among the charging mode, rest mode and discharge mode in a predetermined time cycle and further performs a mutual control between the respective battery groups so that at least one battery group is placed in the rest mode in a predetermined sequence during the operation thereof.  As a result, the drawbacks of a conventional pulse type charging and burp charging unit, which are suitable for a quick charging but which requires a large instantaneous charging current which causes the size of the charger to increase are eliminated.
