Patent GB-2351347-A (GB)
Title: Inspecting printing state of pattern eg on a printed circuit board
Inventor: TOMOMATSU MICHINORI
IPC: G06T7/00
Filed: 2000-05-23
Abstract: For the inspection of the printing state of printed material such as a printed circuit board (6) having a solder paste pattern screen printed through a mask, the mask produces a test portion (6d) separate from the required pattern portion (A). The test portion is inspected after printing eg by a camera movable along X and Y axes. The acceptability of the entire substrate is judged on the inspection results of the test portion, thereby providing inspection of the necessary accuracy easily and at low cost. The test portion is created on an area having a high risk of having a defect, such as the periphery of the substrate outside the required pattern portion (A) or an unprinted space near the edge but inside the required pattern portion. The test portion is printed with a pattern having a pattern element dimension smaller than the minimum required pattern element dimension.

Title: Downloading and uploading data in information networks
Inventor: CUDD RICHARD
IPC: G06F17/30
Filed: 2000-09-01
Abstract: Downloading or uploading data via a client-server communications network, the network comprising a plurality of clients each having a local cache storing data downloaded via the network. In response to a data request made by a first client to a server on the network, the requested data is uploaded from the cache of a second client (acting as a proxy server client) after referral by the server and the requested data is transmitted across the network to the first client. This allows sharing of cache content between clients without having to access an external source server for a new copy of the information. This referral method may be used if the server on the network receiving the request for the content cannot provide the data within a predetermined time period or does not have the data available. The server may provide a list of clients from a look-up table that have the data available and the method may include means for determining the best client from which to receive the data by for example checking the connection speeds and determining the client with the best connection. Furthermore the first client may have selection means for choosing the second client which is to provide the data by having a target connection speed and downloading the data from the first of the clients contacted that meets the target.

Patent GB-2358435-A (GB)
Title: Engine control strategy using dual equal cam phasing combined with exhaust gas recirculation (EGR)
Inventor: STEIN ROBERT ALBERT
IPC: F02M25/07
Filed: 2001-01-16
Abstract: The invention comprises a strategy and method for phase shifting intake and exhaust valve timing relative to crankshaft position as a function of engine operating variables. This strategy includes cam retarding steps at part load whereby valve overlap is delayed to obtain improved fuel economy resulting from a late intake valve closing to reduce pumping work during the intake and exhaust strokes. The exhaust gases are drawn into the combustion cylinder of the engine during the intake stroke, which reduces oxides of nitrogen in the exhaust gas and reduces unburned hydrocarbons. Improved thermal efficiency and reductions in oxides of nitrogen are achieved as the combustion charge is diluted at higher loads by an external exhaust gas recirculation system, thereby combining the effects of exhaust gas recirculation and dual equal variable camshaft timing to obtain fuel economy benefits that cannot be achieved with either a conventional EGR system acting alone or dual equal variable camshaft timing acting alone.

Title: Compact optical sensing system
Inventor: SARMAST SAM
IPC: G01J1/02
Filed: 2002-09-24
Abstract: A compact optical sensing system (Fig 1, 100) is used in hardcopy devices (Fig 1, 20) for scanning and/or printing images, for instance, using inkjet printing technology in desktop printing or in photographic printers appearing in grocery and variety stores. Several light emitting diodes ("LEDs") 120, 122, 124, 126 illuminate a sheet of print media 169, and one or more photodiodes 108, 110 receive light reflected from the sheet. The photodiode generates signals in response to the light received, and the hardcopy device uses these signals to adjust printing parameters for optimal print quality. Using a chip-on-board process, the bare silicon die for each component is wire bonded directly to a printed circuit board assembly 105, allowing at least four LEDs (blue, green, red and soft-orange) to be grouped closely together in a space smaller than that occupied by a factory-made, single-packaged LED. A calibrating system (Fig 8, 300) uses a white target (Fig 8, 370) covered for cleanliness by a windowed door (Fig 8, 350) which is opened/closed by a printhead carriage (Fig 8, 320).

Title: Sand screen with integrated sensors
Inventor: RESTARICK HENRY L
IPC: E21B47/10
Filed: 2001-07-13
Abstract: There is a need to better understand well conditions during gravel pack completions and during production through a gravel pack. The sensors (102) that are used to determine the conditions at the actual interface between the gravel pack and the production interval are located directly on the gravel pack assembly (100). This allows for the most accurate and timely understanding of the interface conditions. Sensors (102) along the length of the gravel pack can provide real time bottom hole pressure and temperature readings. Other sensors (102) could provide information on flow rate of fluids produced as well as density measurements. Thus, during completion, the sensors (102) can provide information on the effectiveness of gravel placement. During production, the sensors (102) could provide instantaneous information on dangerous well conditions in time to minimize damage to the well equipment.

Title: Digital video apparatus allowing simultaneous viewing and recording
Inventor: KIM SUNG-SOO
IPC: H04N5/76
Filed: 2003-02-28
Abstract: An apparatus for allowing digital video image replay comprises an input image signal buffer 100, replay control unit 101, memory control unit 102, memory store unit 103, second or output buffer 104 and switching unit 105, transmitting output signals to a decoder. Buffers 100 and 104 serve to synchronise the signals with the control unit 101. The apparatus operates in two modes: firstly, a 'replay off' mode where an input video signal may be concurrently viewed, via a direct connection between input and output, and recorded in memory or store 103. Secondly, in a 'replay on' mode, a predetermined portion of recorded image signal may be accessed from memory 103 and output to a decoder via switch 105. Each mode of operation is controlled by a user input signal, via replay control unit 101 and switch 105. Writing of digital video signals to memory 103 may be stopped when stored signals are being read from memory 103. The memory or store may be cyclically addressed, input signals overwriting those already existing in the memory. The apparatus allows portions of a television programme, for example those missed when answering a telephone, to be replayed.
