Title: Electromagnetic shielding of components on a circuit board
Inventor: LAWRENCE JOHN MICHAEL WALMSLEY
IPC: H05K9/00
Filed: 1995-06-29
Abstract: An electromagnetic shield (10) adapted to be fitted to a circuit board (31) for screening components (32) thereon. The shield comprises a main portion (11) (Fig. 1(a), not shown) made of a wire mesh, and a peripheral wall portion (12) depending from the main portion and consisting of a plurality of evenly-spaced vertical wire legs (13) extended from the mesh. The wire legs serve to support the shield above the circuit board and to connect the shield to ground. The pitch of the wire legs is chosen to provide a desired shielding effect at the periphery of the shield. In another embodiment (Fig. 5(a), not shown) the main portion of the shield (50) is strengthened by a plastic sheet (51).

Title: Anchoring structure for off shore beach net
Inventor: KVAM HARALD
IPC: A01K61/60
Filed: 1995-07-21
Abstract: The nets anchoring structure consists of an anchorage block 20 encased in a housing 22 and a chain 26 attached to anchorage block for locking to a long horizontal cable 28. The net is then secured along its bottom edge to the horizontal cable, thus tethering it the seabed. In addition, the anchoring structure has a dome shaped cap 32 that is tied to the chain in a manner that allows the cap to turn about a vertical axis. The cap covers the locking joint between the cable and chain, thus inhibiting the net from catching or tearing on the cable/chain joint. The cap features a channelled recess cut along its flat surface, this accommodates the cable. A continuous protective barrier structure (12) (Fig. 1) is provided around the beach net. The barrier extends seaward from the perimeter of the net and presents a highly visual warning for, and a physical barrier against oncoming boats. <IMAGE>

Title: DFB fibre lasers
Inventor: KRINGLEBOTN JON THOMAS
IPC: G01L11/02
Filed: 1996-03-20
Abstract: A DFB fibre laser 4 doped with one or more rare-earths is provided with distributed feedback via a fibre Bragg-grating, which gives rise to only two orthogonally polarised wavelengths. The separation between the wavelengths may be tuned by changing the birefringence of the fibre, the beat frequency being detected by a polarizer 5, photodetector 6 and frequency analyzer 7. The laser may be applied as a polarimetric sensor in which an asymmetrical force changes the wavelength separation, or as a tunable two-wavelength source. A particular preferred field of application is for measuring the pressure in pipes, to determine the flow.

Title: Electronically controlled camera
Inventor: NOMURA HIROSHI
IPC: H05K3/28
Filed: 1997-01-24
Abstract: The present invention relates to an electronically controlled camera which has a lens system driven to move along an optical axis thereof by a motor.

Title: Cell phone base station booster with power control loop from either booster output or existing amplifier output
Inventor: KINGSWOOD ANDREW CHRISTOPHER
IPC: H04B1/38
Filed: 1997-03-27
Abstract: Power control of output RF signals in a mobile radio communication network is described. A base transceiver has a booster module attached for increasing the power of the output RF signals. A power levelling loop controls the transmission power of the unboosted transceiver. When a booster module is attached, the loop is extendible to control the power of the boosted RF signal output from the booster module. A node connects the amplifier circuit of the transceiver and booster module. The node allows an RF signal to be supplied from the amplifier circuit to the booster module for transmission. The node also forms part of the extended power control loop and allows the detected level of the boosted signal to be returned to the transceiver. Switch 36 selects either the extended or unextended loop.

Abstract: An harmonic generator system for generating at least two output beams (6a, 6b, 6c) of higher order harmonic radiation from an input beam (1) of radiation of frequency # comprises at least two non linear optical crystals (3a, 3b, 3c) arranged in series. Radiation output from each crystal stage has first and higher order harmonic components. Chromatic separators (5a, 5b, 5c) separate beams of radiation output from each crystal and selected beams are then passed through a telescope (9a, 9b) to the next crystal in the series, thereby generating further radiation beams of first and higher order harmonics. Multiple beams of second, 2#, third, 3#, or fourth, 4#, harmonic radiation may be output from the system and may he used to pump various stages of a secondary laser system or a optical parametric oscillator. Alternatively, the output beams of higher order harmonic radiation may be coherently combined to form a single output. The system is capable of yielding considerably high conversion efficiencies, approaching 100 %. The system for generating multiple beams of second harmonic radiation preferably comprises a three non linear crystals, for example potassium titanyl phosphate (KTP) or potassium dihydrogen phosphate (KDP), such that three beams of second harmonic radiation are generated. The telescope magnifications may be variable so that the relative intensity of radiation output at each crystal stage may be varied.
