Title: Detection of improper cpu operation from lap time pulses and count of executed significant steps
Inventor: HIRAO MANABU
IPC: G06F11/00
Filed: 1993-09-29
Granted: 1999-04-06
Abstract: In a CPU monitoring apparatus, a lap time pulse, which is generated by the CPU in response to successive executions of a program, is monitored and determined whether its duration is between maximum and minimum values, or longer than the maximum value or shorter than the minimum value, and a program execution alarm signal is generated when the duration is either determined to be longer than the maximum value or shorter than the minimum value. The apparatus further determines whether the CPU has successfully or unsuccessfully executed a predetermined number of significant steps when the CPU has repeatedly executed the program a predetermined number of times, and generates a step execution alarm signal if the CPU is determined as having unsuccessfully executed the predetermined number of significant steps.

Title: Modular concrete floor slab
Inventor: GRATTON JEAN-CLAUDE
IPC: E04B5/08
Filed: 1994-03-17
Granted: 1996-02-13
Abstract: A precast concrete floor slab for a structural floor system has a flat floor panel of polygonal form, with a peripheral perimeter beam around the outside of the floor panel and intermediate beams radiating from the centre of the floor panel to the perimeter beam. In use, the slab is supported at its corners on piles, with adjacent slabs being arranged side by side to cover the necessary floor area. No grade beams are required as the perimeter beam of each slab provides the necessary structural strength for supporting the building. The intermediate beams under the slab allow the thinning of the slab to reduce the overall amount of concrete used. The slabs are fastened in place with loops of the slab reinforcement that project from the slab at the corners for connection to the reinforcement of the piles supporting the slabs.

Abstract: A switching system (10) is modified to provide, in addition to conventional connections (110 + 111) between ports (100, 103), eavesdropping connections that couple only one-half of a conventional bidirectional connectionbetween a pair of ports to a third port (102). If the pair of ports serves an adjunct processor such as a voice-mail system (11) and a user voice terminal (13), a voice- or speech-recognition unit (12) serving the adjunct processor may be connected to the third terminal to receive thereat only the transmissions (112) of the user voiceterminal without the unwanted transmissions of the adjunct processor. If the transmissions of the user voice terminal are polluted with echoes of the adjunctprocessor transmissions, then each half of the conventional connection between the adjunct processor and the user voice terminal may be connected to a different one of two ports (102, 103) serving the voice- or speech-recognition unit, whereby the recognition unit is able to receive the polluted transmissions (112) of the userterminal separately from the transmissions (113) of the adjunct processor and use the latter to perform echo cancelling functions on the former so as to obtain only the transmissions of the user voice terminal without the unwanted transmissions of the adjunct processor.

The body has a cavity connected with the access opening and commun icating with the inlet port and outlet port to allow fluid flow through the valve body. A pair of discs (16) (18) with orifices (44) (54) are positioned within the cavity to control flow into the outlet port by rotating one of the discs to chan ge the degree of alignment between the disc orifices. A sleeve (22), a wear sleeve (14) and a rotatable cylinder (20) are lo cated within the cavity to control flow from the inlet port. The sleeve and the cylinder both have side walls with a set orif ices (68) (90). One disc (18) is secured within the open end (60) of the rotatable cylinder and the other disc is secured to the wear sleeve. By rotating the cylinder, the alignments of the sleeve orifices (90) with the cylinder orifices (68) and the o rifices of the two discs (44) (54) are changed to control flow through the valve. A cover (24) is removably attached over the a ccess opening and secures the sleeve, the cylinder, the wear sleeve and the discs in the cavity. The cylinder and the wear sleeve have sets of flanges or threads which cooperate to allow the cylinder and the wear sleeve to be installed into and rem oved from the valve body separately or together. The valve may also be constructed without the sleeve.

Granted: 1998-12-15
Abstract: An automatically controlled water spray-based air purification system having a humidification portion and a dehumidifying portion is operatively installed in an air handling unit used to recirculate air within a conditioned space.  A blower within the air handling unit housing operates to draw return air into the housing, flow the air across the entire air purification system, and then discharge the purified and humidified air back into the conditioned space. Upon sensing an excess humidification of the air, a humidistat operates a supply air/return air damper system to cause a portion of the air interiorly traversing the housing to bypass the humidification portion of the purification to thereby reduce the moisture content of the air discharged from the unit. A water spray portion of the purification system is served by a pump forcing water from a sump structure through a filter, with the spray water draining back into the sump after cleansing air traversing the purification system.  Upon a sensed demand therefor, an additive injector adds suitable chemical treatment material to the sump water, and a water pollutant monitor structure operates to backwash the filter upon sensing an undesirable pump back pressure increase or a buildup of particulate and gaseous pollutants in the sump water.
