Title: Estimation of column cardinality in a partitioned relational database
Inventor: HAAS PETER JAY
IPC: G06F17/30
Filed: 2000-08-28
Abstract: Column cardinality for a table in a partitioned relational database is estimated. In each node in the database containing partitioned portions of the table a hashing function is carried out to generate a hash data set for each node, according to one of sample counting, linear counting or logarithmic counting techniques. The hash data sets are merged in a coordinator node to generate a combined hash data set. The combined hash data set is counted and corrected according to the appropriate sample counting, linear counting or logarithmic counting techniques. The resulting count is adjusted for hash collisions and the resultant value is used to estimate the column cardinality of the table.

Inventor: WU KUANG-YI
IPC: H04B10/29
Filed: 1999-03-05
Abstract: An optical add/drop wavelength switch is controllably changed from a bridge state, in which output is identical to input, e.g. a Wavelength Division Multiplexed (WDM) input, and an add/drop state, in which a signal input to an add port is substituted for a particular wavelength subrange of the WDM input, other wavelengths of the WDM input being unchanged. In one embodiment, the wavelength subrange of the WDM signal is given a polarization different from other wavelengths of the WDM, such as by using a stacked waveplate or other optical filter or polarization discriminator. The differently-polarized wavelengths can be spatially separated, e.g. by a birefringent element or a polarization beam splitter, preferably in a bit-controlled fashion, such as by using a liquid crystal or other polarization controller. Polarization controllers and discriminators can be used similarly to selectably align or combine the add signal with the portion of the WDM signal outside the subrange. The add/drop wavelength switch can be used, e.g. in an optical token ring network and/or to make-up an optical crossbar for exchanging any arbitrarily designatable channels, e.g. among a plurality of multi-channel optical fibers.

Inventor: SAMPATH PARTHASARATHY
IPC: F23R3/00
Filed: 1999-05-25
Abstract: The invention provides a cold combustor wall for lining the hot combustor wall of a gas turbine engine, disposed at a distance from the outer surface of the hot combustor wall.  Improved cooling of the the hot combustor wall results from the addition of impingement cooling air injected through orifices in the cold combustion wall directed at the hot combustion wall.  The cold combustor wall has an outer surface in contact with cool compressed air and includes a pattern of air impingement inlet orifices through the cold combustor wall for conducting compressed air from the outer surface of the cold combustor wall in compressed air jets directed at the outer surface of the hot combustor wall. The provision of a cold combustor wall improves conventional air film cooling by adding impingement cooling and reusing the air after impingement to form the conventional air film. The invention is equally applicable to hot combustor walls using conventional effusion cooling and splash louver cooling film systems as well.
Patent CA-2335215-A1 (CA)
Inventor: EASTON DAVID JOSEPH
IPC: B62D11/18
Filed: 2001-02-09
Abstract: A tracked vehicle has an electrohydraulic drive/steering system having an engine driven variable displacement hydraulic steering pump which drives a hydraulic steering motor which is coupled to a differential track drive mechanism via a transmission with multiple gear ratios. A steering wheel is coupled to a variable friction device which produces a variable friction force which resists rotation of the steering wheel. A  control system is responsive to a position of the steering wheel and controls the steering pump displacement and controls the friction device. The control system sets the variable friction device to its high friction level when a limit of the steering pump displacement is reached when the transmission is in a higher one of its gear ratios.

Abstract: In an interface device for interfacing a telephone instrument, such as a headset, a handset, a modem, or a teleconferencing device, to the handset microphone input port of a telephone set base unit, the transmit signal leve l applied to the microphone input of the base unit must be set to an appropria te level. The appropriate level is determined according to the type of micropho ne the telephone set base unit is configured to interface with. The microphone can be carbon, electret or dynamic. The interface device detects the type of  microphone the base unit is configured to interface with by detecting the DC  characteristics of the microphone input port. Then, the interface device determines the appropriate transmit level by correlating the DC characteristics to one of a plurality of predetermined transmit levels. Thes e levels are stored in a table. The transmit signal level is then automaticall y set according to a selected one of the predetermined transmit levels. Alternately, a test signal is applied to the microphone port of the base uni t to determine its input characteristics and, then, the transmit sensitivity i s set based upon this determination. A test signal can alternately be applied to the microphone located in the handset to determine its type or characteristi cs and, then, the transmit sensitivity is set based upon this determination. As  an enhancement, receive sensitivity is adjusted for signals received from a handset speaker output port.

Title: Agitation device
Inventor: GASTGEB RAYMOND FREDERICK
IPC: B01F15/00
Filed: 1999-07-13
Abstract: An agitator (102, 802, 902) capable of generating complex mixing motions is described. The agitator includes a movable assembly (104) that is suspended,  via several resilient supports (128), from a frame (130). The movable assemb ly receives a vessel containing a material(s) to be agitated. The movable assembly includes spaced upper (106) and lower (112) plates having a rotatab ly- supported member (118) disposed therebetween. The mass of the rotatably- supported member is asymmetrically distributed about its rotational axis. A drive means (136), such as a directed air flow, causes the rotatably-support ed member to rotate. Due to the asymmetric mass distribution of the rotatably- supported member, force is non-uniformly applied to resilient supports such that, at any given time, some of such resilient supports are subjected to a compressive force while other resilient supports are placed under tension. T he movable assembly is placed in orbital motion and agitates the material(s) within the vessel disposed thereon.
