Filed: 2001-10-12
Abstract: The present invention provides a method of alignment between sheet materials, a method of alignment, a substrate assembling method, and an aligning apparatus, which are capable of easily and surely performing highly accurate alignment and suppressing a reduction in material yield. After alignment performed based on a band-like light as a reference, alignment is performed based on a joint of a condenser lens portion of a lenticular lens as a reference. More specifically, the deviation of a liquid crystal display cell in a rotational direction is corrected by using a light emitted from a light source and condensed to be band-like at the lenticular lens as a reference. Subsequently, by changing a depth of focus of a microscope, measurement is performed for positions of a black matrix of the liquid crystal display cell and the joint of the condenser lens portion of the lenticular lens. Then, based on the result of the measurement, horizontal alignment is performed between the liquid crystal display cell and the lenticular lens.

Abstract: L'invention concerne une technique permettant d'éliminer et de récupérer le CO2 des gaz d'échappements d'une centrale énergétique et/ou thermique (centrale principale) respectivement par absorption et désorption chimiques. Le gaz d'échappement est dirigé vers un absorbeur utilisant un absorbant chimique où le CO2 est absorbé, créant un écoulement de gaz appauvri en CO2. L'absorbant riche en CO2 vient ensuite alimenter un désorbeur, où le CO2 est éliminé de l'absorbant qui, pratiquement exempt de CO2, est remis en circulation vers l'absorbeur, le CO2 gazeux désorbé étant déchargé. Le gaz d'échappement est refroidi et recomprimé à une pression élevée dans un compresseur d'une centrale secondaire intégrée à la centrale principale, à l'absorbeur et au désorbeur, avant de pénétrer dans l'absorbeur. Le gaz d'échappement appauvri en CO2 sortant de l'absorbeur est réchauffé puis expansé dans un expanseur au sein de ladite centrale secondaire.

Title: Optical member with layer having a coating geometry and composition that enhance cleaning properties
Inventor: ARNEY MICHAEL S
IPC: C03C23/00
Filed: 2000-03-07
Abstract: An improved transparent optical member, preferably a glass sheet, comprising  a nanostructure layer with an enhanced geometry and a balance of chemical (hydrophobic and hydrophilic) characteristics can be formed on a surface. Th e geometry and chemistry of the layer combine to obtain improved washability. The layer can be manufactured by forming a layer comprising a silicon compou nd coating, including a silicon oxide coating, a silicon carbide coating, a silicon nitride coating or mixtures thereof. The coating can have a thicknes s of about 1 to 100 nm (10-9 meter). The layer has a preferred rougheness from  a random or ordered array of structure. The layer can be doped with di tri or polyvalent metal compounds. Such coatings have been found to have increased washability and such coatings have been found to preferentially bind to aqueous solutions applied to the glass. The hydrophilicity and prefential binding to aqueous solutions (wetability) tends to displace any soil deposit ed or contacted with the glass surface. As a result, the glass tends to associa te with aqueous solutions and to disassociate soil when contacted with aqueous solutions substantially increasing the ease of cleaning the glass surface using water, aqueous cleaning solutions, etc.

Title: Sensor system
Inventor: SLADE IAN ROY
IPC: G01S5/06
Filed: 2000-02-21
Abstract: A sensor system (10) for locating transmitters incorporates three vehicle-mounted patch antennas (30 to 34), a signal processing unit (40), a navigation unit (50) and a computer (60). The navigation unit (50) measures sensor system position using the Global Positioning System. The antennas (30 to 34) receive radiation from a transmitter (210) to be located and respond by generating output signals which are frequency downconverted and processing coherently by a digital signal processing unit (230). This produces elevation and azimuth phase data for the computer (60), which determines measured phase differences. The computer (60) also calculates expected phase differences from antenna positions and trial transmitter positions. It determines transmitter location from correlation between measured and expected phase differences. The position of a transmitter (210) is determined for a number of sensor system positions.

Title: Method and apparatus for broadcasting system information in a cellular communications network
Inventor: WIBERG NICLAS
IPC: H04W48/12
Filed: 2000-05-19
Abstract: In a cellular telecommunications system or network, tags are associated with one or more system control parameters.  For example, a given tag value may be indicative of particular values for one or more system information parameters. In each cell, a base station (BS) transmits or braodcasts currently valid tag values. System information blocks including the system information parameters themselves (which correspond to particular tag(s)) are also broadcast by base stations. A mobile station receiving a valid tag value from a base station determines whether or not it has to read system information block(s) corresponding to that tag depending upon whether the base station has already stored or cached such block(s) corresponding to the tag value. As will be appreciated by those skilled in the art, different embodiments of the instant invention may result in the mobile station not having to re-read identical system information each time it changes cells, or while moving in the same cell. This may conserve radio resources and reduce battery consumption, thereby improving standby time of the mobile station.
