Title: Intake air control strategy for an i c engine having a hybrid valvetrain
Inventor: ROBICHAUX JERRY D
IPC: F02D41/00
Filed: 2001-08-02
Abstract: The engine has at least one randomly operable intake valve 16, eg electro-magnetically or electro-hydraulically actuated, and at least one selectable intake valve 18, ie cam-actuated and with a deactivator. The engine also has exhaust valve(s) 20, an intake throttle valve 14 and a control unit 26. Based on demanded engine torque, an operating parameter such as intake manifold pressure and transition type, the throttle position and closing time of the randomly operable intake valve 16 are determined such that a smooth transition, eg between activating and deactivating the randomly operable intake valve or the selectable intake valve, can be accomplished. The engine speed may also be sensed and desired fresh trapped charge may be computed on the basis of engine speed and demanded engine torque.

Title: Use of a barrier layer on a Cu substrate when using a Sn-Zn alloy as solder
Inventor: YAMAGUCHI ATSUSHI
IPC: H05K3/24
Filed: 2002-12-23
Abstract: A barrier metal layer 3b,9b is provided on at least one of the electrodes 3,9 formed on a substrate 1 and an electronic component 7, so as to coat a base material 3a, 9b of the electrode, which base material is made of a material containing Cu.

Title: A flexible surfboard propellable by means of a riders movement
Inventor: WHITE KEVIN
IPC: B63B35/79
Filed: 2003-09-10
Abstract: A stiffly resilient surfboard that a rider by shifting his weight and position across the deck can cause to flex longitudinally. With correct timing and balance the rider is capable of creating continuous undulations that travel nose to tail throughout the surfboard. The effect these undulations have upon the surrounding medium is enough to overcome resistance therein and is subsequently capable of propelling the surfboard and rider through water when required. The hull of the surfboard is curved convexly upward throughout its length. The nose, deck side is bevelled from the tip. Whilst the board is flexed convexly downward, the angle of the bevel relative to horizontal is greater than the angle of the bevel when the board is flexed convexly upward. The surfboard may be fluted or ribbed. The surfboard may be buoyant enough to support the rider. It may be usual surfboard shape and be of light plastics material such as polyethylene foam, which may be coated or laminated with other materials. The surfboard may be equipped with accessories such as foot straps fins and leashes.

Title: A predistorter for a polar transmitter, using look-up tables and interpolation, and possessing a simple training procedure.
Inventor: O'SULLIVAN ROBERT
IPC: H03F1/32
Filed: 2003-11-05
Abstract: An amplitude predistorter for an EDGE polar RF transmitter comprises a look-up table 205 containing a small set of input-output values defining a piecewise linear model of the amplitude response of the amplifier (105, figure 1). The two input-output value pairs defining the segment in which the input amplitude lies are fed from the LUT 205 to a linear interpolator 204. A phase correction look-up table may be provided also (figure 4). The precorrection unit 201 provides scaling and offset to match the input signal range to the available amplifier output range. The contents of the look-up tables may be determined relatively promptly and without iteration during a training mode, using a low-bandwidth Cartesian receiver (106, figure 1). The LUT 205 may contain a bitmap denoting whether each segment end point is above or below the input to the LUT. The priority encoder 203 operates on the bitmap output to select a segment.

The protection element 5 is freely rotatable about the guidewire apparatus. A tracking member disposed adjacent the distal end of the guidewire apparatus can be used to guide the device along another guidewire. Thrust bearings may be employed to facilitate unlimited rotation of the steerable guidewire within the protection element, especially while the protection element is retained in the collapsed configuration.

Title: Control lever device with a sprung plunger engaging a roller
Inventor: MIYAKAWA TOSHIKI
IPC: A63F13/245
Filed: 2004-07-30
Abstract: A control lever device has a lever 32 rotatably supported about a shaft 40 on an inner frame 30 for movement in a first direction X, and rollers 34a,34b attached in the inner frame 30 to allow the control lever to be positioned and secured at first and second displacement positions A,B located on a straight line by a sprung plunger 42 at an end of the lever 32 engaging and passing over the rollers. An outer frame 26 supports the inner frame 30 for movement in a second direction (Y, fig 2) at right angles to the first direction. A path control section 28 controls a path of the lever 32 within an H-shaped groove, or can be replaced with a path control section with three parallel joined grooves.. Switches (36a,36b,52a,52b, figs 4A-7) or other sensors detect positions of the lever 32 in both directions. An embodiment has only one roller, and another only detects movement in the first direction. A coil or rubber spring 50 biases the inner frame 30 towards a neutral position. The device feels like a vehicle gear shift, and can be used in a car driving simulator or game (fig 8).
