Title: Automatic tuning of MRI RF coils
Inventor: VANHETEREN JOHN
IPC: G01R33/3415
Filed: 1994-10-17
Abstract: A MRI RF front end 32 has transmit and receive channels to which a plurality of coils 22 can remain attached during operation (including RF coils having differing types of matching circuits), and facilitates switching between a plurality of attached coils. Methods and apparatus for selectively tuning differing RF coils, including both high power coils 22B, 22C and varactor-tuned coils 22D are described. The tuning of a high power coil involves using a remote impedance match tuning network RTU (fig. 7) for a coarse tuning operation and, if necessary, a fine tuning operation. In performing the coarse tuning operation separately for In-Phase ("I") and Quadrature ("Q") channels, a tuning controller determines the effective load impedance of each of the RF coil channels by quadrature demodulation of their reflected signals. The tuning controller then uses a model of the tuning network to set coarse values for the adjustable impedances of the RTU. In tuning varactor coils, the tuning controller chooses a starting point and then executes a two-dimensional bisection search operation to locate a candidate for the tuned point. This is followed by a starburst operation for examining the magnitude of reflected signals at points in a starburst or asterisk pattern about the candidate point. <IMAGE>

Title: Signal processor system for a phased array antenna
Inventor: PERROTT ROGER ADRIAN
IPC: H01Q3/36
Filed: 1996-09-04
Abstract: A signal processor system 10, 20 for the transmission or reception of orthogonal or non-orthogonal beams. In a transmission mode, a transmission signal from a transmitter 11 is routed throuth a diplexer 13 and divided into two equal sub-signals by a hybrid coupler 15. The phase of the two sub-signals are independently adjusted by phase shifters 16 and fed to the inputs of a beam transformer 17 as a first set of sub-signals for recombining to form aperture excitations required for a first beam. Resetting each phase shifter 16 to an alternative phase setting causes the recombination of a second set of sub-signals and results in the formation of aperture excitations required for a second beam. The reception mode is essentially the inverse of the transmission mode with the exception of the diplexer 13 switching received signals to a receiver 12.

IPC: A44B19/30
Filed: 1997-10-28
Abstract: An auto-lock slide fastener comprising a slider body 1 formed with an insertion hole 14, and a locking leaf spring 3 formed with a locking pawl 24. The locking leaf spring 3 is formed with a hook 25 and is mounted on the slider body 1 so that the locking pawl 24 is inserted in the insertion hole 14 and the hook 25 is slidably engaged with a lug 10 on the slider body 1.

Title: Self adhesive magnetic or electromagnetic tapes
Inventor: HODGSON MARTIN
IPC: C09J7/50
Filed: 1999-01-23
Abstract: A tape comprising a backing film with a fragile magnetic or electromagnetic coating of a pigment in a binder medium, which optionally may also have a release coating interposed, is coated with a pressure sensitive adhesive. The adhesive is overcoated on the fragile coating or is applied to the reverse side of the backing film. Either the reverse side of the backing film also has a release coating applied, or a release inter-liner is placed over the adhesive before the tape is wound into a roll. When unrolled, the tape may easily be adhered to a substrate, under very light contact pressure. The products so made are able to carry magnetically recorded data, for information or security uses, or to act as electromagnetic screens / barriers. Existing products intended for similar uses have to be applied with the use of heat and pressure, preventing use on sensitive substrates.

Title: A power control arrangement for a mobile telephone system transmitter in which the feedback loop gain is adjusted to limit the power change per step
Inventor: OBARA TOSHIO
IPC: H04W52/04
Filed: 1999-04-09
Abstract: A measured value for the transmitter output is compared at 20 with a target value derived at 18 from a transmit power designator 16 to derive an error signal E. A loop gain setting portion 21 generates a signal G which multiplies E to produce signal F. This loop gain adjustment is done to limit the power adjustment per step (controlled by timing controller 25 and latch 26). This may improve the power control accuracy and reduce distortion and may also be suitable for different transmission modes. Use in wide band CDMA is described.

IPC: B29C67/00
Filed: 1996-11-22
Abstract: A product building system uses a stage (13) movable in X-Y-Z directions for holding and moving a product. A fixed laser (1) is focused on a spot on the product while strips of materials (7) are fed tangent to a forming direction from two sources (6, 32) on a rotating platform (11).
