Patent CA-2332827-A1 (CA)
Title: Drive control method for photosensor system
Inventor: NAKAMURA YOSHIAKI
IPC: H04N5/353
Filed: 2000-03-28
Abstract: The read processing time of a single screen is shortened by allowing the processing cycles for the rows to partially overlap with each other, the reset period, the pre-charge period and the read period are prevented from being overlapped in time with each other, making it possible to perform the read operation accurately.      Also, in the drive control method above, the charge accumulating time for the rows is changed after the rows are reset simultaneously or successively, and the read operation is performed. As a result, it is possible to obtain an image read with the charge accumulating periods differing in an amount corresponding to the number of rows, i.e., with the detection sensitivities differing in an amount corresponding to the number of rows, by the read processing of a single screen, making it possible to extract the valued of an optimum detection sensitivity based on the image data thus obtained.

Patent CA-2338267-A1 (CA)
Title: Rolling machine
Inventor: BEIERLING HANS-JURGEN
IPC: B21C37/10
Filed: 2000-05-22
Abstract: The invention relates to a rolling machine for working a metal container having a longitudinal seam, especially a sheet steel container, in which a cylindrical body is bent out of a flat metal plate and the adjacent edges of the cylindrical body can be welded to one another, after which a discoid underside and, optionally, a corresponding top side are welded to the cylindrical body (=intermediate product) in order to form a closed container or a container which is open at the top. The problem posed by this method is that the inner welded seam edge is often depicted as the cause of early rust formation which results in the contamination of the filling item. According to the invention, the rolling process is carried out in a continuous rolling machine (18) in which a body (12) is loaded into the one station (=loading position A) and a finished body (12) is simultaneously unloaded in the other station (=unloading position B). To this end, the top inner roller supporting part (26) is centrally mounted. During the rolling process, the rolling device is mounted on the exterior. The distinctive feature of the continuous rolling machine (18) is in the, so to speak, "floating in an alternating manner"  bearing of the top roller supporting part, i.e. it is equipped with an alternating locking device or fixing bearing which is placed centrally and on the exterior.

IPC: E06B9/307
Filed: 2001-03-21
Abstract: A Venetian blind includes a tilt means having multiple ladder strings for tilting slats of the blind connected to the ladder strings. Each of the ladder strings includes a front and a rear vertical strings, and a plurality of transverse ladders spaced between and along the front and the rear vertical strings. Upper ends of the two vertical strings are upward extended to provide a front and a rear hanging section, respectively, without any transverse ladders spaced between the hanging sections.

Title: Compact folding row marker
Inventor: HILVERS MICHAEL J
IPC: A01B69/02
Filed: 2001-05-01
Abstract: The present invention provides a folding row marker assembly for use with an agricultural implement. The folding row marker assembly has an inner link assembly with at least one inner link member and a mounting adapted to attach to the agricultural implement. The folding row marker assembly further comprises a plurality of first arm members that hingedly connect to both the first link assembly and an outer link assembly having at least one outer link member. In one embodiment, the folding row marker assembly has two sections, where the second section is an outer arm member that hingedly connects to the outer link assembly and connects to a marker preferably through a shear bolt. In an alternative three-section embodiment of the folding row marker, the outer link assembly further comprises a plurality of outer link members that combine to add a middle section containing a middle link assembly that connects to the inner arm members, an outboard link assembly that connects to the outer arm member, and a plurality of middle arm members that connect the middle link assembly to the outboard link assembly. In both embodiments, a radial motion of the inner arm members around the inner link assembly causes the outer arm member to move in a controlled radial motion around the outer link assembly, relative to the inner arm members. The radial motion of the inner arm members around the inner link assembly is caused by an actuating mechanism, such as a hydraulic cylinder, that connects to an inner link member and to one of the inner arm members. As a result, the folding row marker assembly moves between a folded storage position and an extended, generally horizontal use position in which the marker engages the ground.

Abstract: A computer displays information in a web page according to geographical information. In a first embodiment, a new HTML tag is defined that allows specifying a geographical location or region. A geographical location specification is set in the web browser, whi ch then displays the web page to the user according to the geographical location specification input by the user. Note that the geographical location may be set manually by a user specifying geographical location or region by inputting information in the computer, such as city, state, zip code, area code, or by pointing to a location on a map. In addition, the geographical region may be set automatically by an internal global positioning system (GPS) detector that detects the geographical location of the computer. In a second embodiment, a geographical location specification is set in the web  browser, and this location information is then transmitted to a web server along with a reques t for a web page. The web server then renders a web page that is customized according to the transmitted geographical location specification. As in the first embodiment, the location may be set manually by a user, or may be set automatically using an internal GPS detector in the computer.</SD OAB>

Abstract: There is provided a decoder and a decoding method for decoding data modulate d with a recursive systematic convolutional code (RSC) in a mobile communicati on system. In the decoder, a branch metric calculating circuit (BMC) calculates  branch metrics (BMs) associated with a plurality of input symbols. An add- compare-select circuit (ACS) receives the BMs and previous path metrics (PMs ) and generates a plurality of path selectors and LLR (Log Likelihood Ratio) data including the plurality of path selectors and reliability information a t a first time instant. A maximum likelihood (ML) state searcher has a plurali ty of cells in an array with rows and columns, connected to one another accordi ng to an encoder trellis, cells in each row having a process time, Ds, for outputting the same value of the cells in the last column as an ML state val ue representing an ML path in response to the path selectors. A delay delays th e LLR data received from the ACS by the time Ds. An LLR update circuit has a plurality of processing elements (PEs) in an array with rows and columns, connected according to the encoder trellis, PEs in each row having a process  time, DL, for generating updated LLR values from the PEs at a time instant (first time instant - approximately Ds+DL) in response to the delayed LLR da ta received from the delay. A selector selects one of the updated LLR values based on the ML state value.

Title: Differential hydrostatic transmission system
Inventor: NOLD RAYMOND V III
IPC: B66D1/44
Filed: 2001-07-16
Abstract: A hydrostatic transmission system for driving a rotatable member includes a differential having an output coupled with the rotatable member, a first hydrostatic drive having an output coupled to a first input of the differential, and a second hydrostatic drive having an output coupled to a second input of the differential. The output of the first hydrostatic drive is rotatable in a first selected direction and at a first selected speed. The output of the second hydrostatic drive is rotatable in a second selected direction and at a second selected speed. A rotational speed and direction of the output of the differential is related to the algebraic sum of the rotational speeds and directions of the outputs of the hydrostatic drives. In one embodiment, the speeds of the first and second drives are maintained above a minimum stable threshold, while operating the rotatable drive at very low or zero speed, by selecting the first direction to be opposite the second direction.
