Inventor: LUNNER THOMAS
IPC: H03H17/06
Filed: 1991-12-13
Abstract: digital filter bank for reducing power consumption by decreasing the number of multiplications carried out therein. There is particularly proposed a filter bank far use in battery-operated applications. The digital filter bank includes a zero-filled digital basic filter [H1 (z)] having a complementary output, and downstream, parallel part-filter banks [H D1; H D2]. In the present context, a zero-filled filter pertains to a filter which maybe based on an LP-filter which is expanded with a number of zero-value filter coefficients between each coefficient in the original filter. The part-filter bank[H D1] connected to the normal output of the basic filter [H1 (z)] is intended to filter-out those filter-bank bands which are pass bands to the basic filter, so that only one of the, filter-bank bands is found on each output signal from said one part-filter bank [H D1]. The other part-filter bank [H D2] connected to the complementary output of the basic filter [H1 (z)] is intended to filter-out those filter-bank bands which are pass bands to the complementary output of the basic filter, so that only one filter-bank band is found on each output signal from he second part-filter bank [HD2].

Patent CA-2103706-A1 (CA)
Inventor: LANGER ROGER L
IPC: B01D53/94
Filed: 1992-03-16
Abstract: The invention pertains to materials which resist combustion and expand when subjected to high temperatures, and are thus suitable for use as mounting mats for monoliths in catalytic converters.  Previously known intumescent materials, such as vermiculite, exhibit contraction between about 100 ·C and 400 ·C, which may cause a monolith to become loose from the casing during warm-up of the catalytic converter. A monolith can be mounted in a catalytic converter by a material containing intumescent vermiculite flakes that have a uniform content of chemically bound water, from 1.0 to 3.2 % by weight and a uniform bulk density, from 0.2 to 0.9 g/cm3. Such a mounting affords good support to the monolith at warm-up temperatures, exerts adequate holding forces at operating temperatures without danger of cracking the monolith, and does not incur gradual reduction in holding forces at operating temperatures.

IPC: G06F9/38
Filed: 1994-03-18
Abstract: A memory controller which makes  maximum use of any processor pipelining and runs a large number of cycles concurrently.  The memory controller can utilize different speed memory devices at their desired optimal speeds.  The functions are performed by a plurality of simple, interdependent state machines, each responsible for one small portion of the overall operation.  As each state machine reaches has completed its function, it notifies a related state machine that it can now proceed and proceeds to wait for its next start or proceed indication.  The next state machine operates in a similar fashion.  The state machines responsible for the earlier portions of a cycle have started their tasks on the next cycle before the state machines responsible for the later portions of the cycle have completed their tasks.  The memory controller is logically organized as three main blocks, a front end block, a memory block and a host block, each being responsible for interactions with its related bus and components and interacting with the various other blocks for handshaking.  The memory controller operates in system management mode to override any write protect status of memory so that the SMRAM can be located in the main memory space and be write protected during normal operations but be full usable during system management mode.

Abstract: Disclosed is a measuring device for measuring the area of a closed curve in which there is provided a body rotating freely along the center of a perpendicular shaft at the state fixed to the ground. For measuring the length, a actuating member sliding horizontally penetrates through the body and is supported thereon. As tracing means for tracing the line of the figure is engaged with the forward end of the actuating member. A rotatation angle of the body is measured in unit of 0.072° by a degree index plate fixed to a fixed shaft, while a moving distance is measured in unit of 0.01 m by a photo-sensor incorporated in the body.            As the tracing means traces the line of the figure on the basis of the central point of the body, area or the figure is divided into a triangle whose on base line is joined with that of the neighboring triangle having same angle. The device for measuring two base lines of the triangle and its included angle uses a law of sines.
