Title: Optimal soft output decoder for convolutional codes
Inventor: DESAI VIPUL A
IPC: H03M13/41
Filed: 2001-02-05
Abstract: Optimal decoding of signals represented by a trellis of block length <I>N</I> divided into windows of length <I>L</I> includes a step of decoding a backward recursion from a point <I>N</I> that is at the end of the block back to the end of the window, and storing the determined state metrics at the end of each window. A next step includes decoding the window using backward recursion from the known state at the end of the window back to the beginning of the window to define a set of known backward recursion state metrics which are stored. A next step includes decoding using forward recursion starting from a known state at the beginning of the window and moving forward. A next step includes calculating a soft output at each stage of the forward recursion using the stored backward recursion state metrics, and branch metrics at each state, and outputting the soft output for that stage.

Title: Screen printing apparatus for a printed circuit board having defect measuring and inspection means
Inventor: YAMASAKI KIMIYUKI
IPC: B41C1/14
Filed: 2001-05-09
Abstract: A screen printing apparatus, for printing creamy solder paste on a substrate by attaching a screen mask 10 to the substrate 6, comprises a laser measuring device 20 mounted in the apparatus for measuring the top surface of the screen mask 10 at a printing position and the top of the substrate 6 at a substrate measurement position by three dimensional measurement and which detects a shape of the substrate or mask and determines whether or not they are acceptable. After screen printing is complete the substrate and screen undergo a printing inspection. The 3D laser measuring device is moved to a different location on the apparatus to perform this task (see figure 2). This provides inspection data of the printing results and data for identifying the causes of failure.

Title: Stroller with spring-biased brake pins
Inventor: LAN RED
IPC: B62B7/04
Filed: 2001-09-27
Abstract: A stroller includes a frame with a rod (15, fig 1), on which a brake pedal (2, fig 2) is rotatably mounted. Pushing the brake pedal downwards moves push rods 32 and positioning pins 43 apart on a mounting rod 31, activating resilient elements 46 to bias brake pins 44 to project from pin holes 415 in mounting seats 41. If a brake pin 44 is not aligned with any of the brake holes 511, it presses against the surface between the brake holes 511, the pin being biased into a hole upon rotation of the wheel. Thus the pedal may be moved to a locked position even if a brake pins is not in a brake hole. Each mounting seat has a bottom cover 42, slots 416,417 and a transverse axle hole 414; while each resilient element 46 has a spring force-storing portion 461 and a pin-driving portion 463 through which a positioning pin 45 of the brake pin 44 passes.

Title: Improved disposable static mixing device
Inventor: FLINT THEODORE R
IPC: B01F5/06
Filed: 2000-06-14
Abstract: A static mixing dispenser (10) provides a circuitous flowpath for plural components to be mixed between the inlet and the outlet of a conduit (12). Coextensive exterior sheets forming a tube can be attached to an interior sheet having openings communicating through the interior sheet. The sheets are sealed together at interior obstructions, forming mixing stages that subdivide and recombine the stream of material. The interior obstructions comprise sheets having openings (80, 85, 90) formed through the thickness of each sheet. The openings each have a flap (100) of sheet material, the partial detachment of which from the sheet forms the opening, leaving a connection of limited area around which the flap can pivot. The flap is thus bendable relative to the sheet so the flap opens during the movement of flowable components in a first direction, and closes during movement of the flowable components in a second direction, forming an array of check valves.

Title: Time sensitive messages for mobile handsets
Inventor: EPHRATI EITHAN
IPC: G07B15/00
Filed: 2002-04-26
Abstract: A time sensitive message such as a coupon for a mobile handset (e.g mobile telephone, PDA) in which the time sensitive message is sent to the handset as a message of a specific type such that a subsequent message of the same type overwrites and hence cancels the time sensitive message. In one implementation, the time sensitive message is sent as a short message service (SMS) of a specific type (i.e. one of type 1-7 in the TP Protocol ID scheme in GSM). Hence, a mobile telephone operator can at any time cancel the time sensitive message by sending another message of the same type to the handset. The subsequent message may be sent whenever the time sensitive message contains out of date information. The time sensitive message may be a permit, a pass, a promotion, stock prices, a competition, football results etc.

Title: Signal enhancement by finding an optimal mapping.
Inventor: HOBSON MICHAEL P
IPC: G06T5/00
Filed: 2003-11-10
Abstract: A method and apparatus for the enhancement of digital signals, for example noise reduction or sharpening of digital images. The method involves finding an optimal mapping between a signal space (or domain) comprising signal values and an alternative optimisation space comprising optimisation parameters. The mapping functions (e.g. wavelet transforms) that are employed are described by mapping parameters. The optimal mapping is found by maximising a mapping quality function (e.g. Bayesian evidence) as a function of the mapping parameters. Once the optimal mapping has been selected, an enhancement process is performed in the optimisation space.
