Title: A mode selection waveguide laser
Inventor: MARKILLIE GAVIN ALAN JAMES
IPC: H01S3/03
Filed: 2010-01-21
Abstract: A mode selection laser 10 comprises a recess (54, 56) which is formed in the surface (24, 26) of an electrode (12, 14) in a waveguide in the laser. The recess (54, 56) provides a region of free space propagation within the waveguide which preferentially selects the lowest order mode. A mode selective RF excited CO2slab laser may be constructed, having a stable resonator in the waveguide dimension and a negative branch unstable resonator in the non-waveguide dimension. The position and size of the recess is considered to provide low order mode selection. The recess (Figures 3a, 3b, 3c, 3d), maybe the circular, rectangular, lozenge shape, or a narrow slot. The laser may have a resonant cavity with a propagation axis. The recess (54,56) may have a length along said propagation access in the range of 0.1 to 1 Raleigh range. They may be application to other types of lasers such as gas discharge, solid-state material, semiconductor material or liquid dye type lasers.

Title: Energy emission event detection
Inventor: SHULMAN ALAN
IPC: G01S3/784
Filed: 2008-11-07
Abstract: Methods and systems for detecting an energy emission event are provided. In a method for detecting an energy emission event, a reference event signal is compared with a received event signal. In some embodiments, the reference event signal is associated with radiated energy having a predetermined temporal response. A detection signal is output when the received event signal corresponds to the reference event signal. In response to outputting the detection signal, imagery of a location in proximity to where the received event signal originated is captured or processed. Using the captured imagery and the detection signal, a determination of where the received event signal originated is made.

Title: A variation of the McEliece public key cryptosystem using a reduced public key
Inventor: TOMLINSON MARTIN
IPC: H04L9/30
Filed: 2010-11-16
Abstract: Improved security and improved throughput of the McEliece public key encryption system first published in 1978 using a relatively reduced public key size. Even though the public key is reduced, in some embodiments of the invention the ensemble of cryptograms produced is identical to the ensemble of cryptograms produced by the original system for a given Goppa code and the same private key. It is possible using this invention that the encrypted message, the cryptogram, is a truly random function not a pseudo-random function of the message so that even with the same message and the same public key a different, unpredictable cryptogram is produced each time. Other embodiments of the invention use a shortened error correcting code allowing the length of the generated cryptogram to match exactly the available transmission or storage media. One embodiment described relates to a method of encrypting data by constructing a digital cryptogram by means of a public key comprising:(a) Constructing a first generator matrix of a binary code with dimension k with a pre-selected Galois field whose base field is 2, and a Goppa polynornial whose degree is such that the corresponding binary code provides a t error correcting capability by utilising n-k parity bits;(b) Constructing a scrambled kxn generator matrix by matrix multiplication, said scrambled generator matrix being the product of a non-singular matrix, said first generator matrix and a first permutation matrix;(c) Constructing a reduced echelon kxn generator matrix by randomly selecting k independent columns of the scrambled kxn generator matrix according to a second permutation matrix;(d) Converting a message to be sent into binary form and formatting it by appending dummy bits as necessary into an integral number r of binary message vectors of length k bits each;(e) Scrambling each binary message vector using a k bit to k bit invertible scrambler;(f) Encoding each scrambled binary message vector by adding rows of said reduced echelon generator matrix according to the 1's in each scrambled message vector to form r codeword vectors of length n bits;(g) Adding to each codeword vector using modulo 2 arithmetic an error vector of length n bits, containing s bit errors where s≤t;(h) Forming a cryptogram from the r said corrupted codeword vectors.

Title: Control of decontamination cycles
Inventor: POMEROY NEIL RICHARD
IPC: A61L2/20
Filed: 2011-01-18
Abstract: A method of controlling a bio-decontamination cycle to decontaminate an enclosed space, such as pharmaceutical clean rooms, isolators and hospital wards, wherein the bio-decontamination cycle comprises a number of phases including at least one gassing phase, during which sterilant vapour is generated and circulated within the enclosed space. The method comprises the steps of continuously measuring the relative humidity or modified relative humidity of the air in the enclosed space and using the measured relative humidity or modified relative humidity to control the steps of the process. There may be two gassing phase parameters, the first of which compensates for variations in relative humidity and temperature and the second compensates for the volume of the enclosed space. Gassing phase parameters can be modified to compensate for the loading of the enclosed space, wherein the loading is determined by the content of the enclosed space which affects the circulation and/or distribution of sterilant vapour. A control module is also claimed.

Abstract: A vehicle is provided with electric energy by magnetic induction. An alternating electromagnetic field is received by a receiving device having a phase line to produce an alternating current. A line arrangement comprising the phase lines has two opposite ends, in a longitudinal direction transverse to magnetic flux lines of the electromagnetic field which penetrate it, and a width measured transversely to both the flux lines and the longitudinal direction. The width gradually decreases along the length of the line arrangement towards at least one of the ends. The line arrangement may form at least one coil whose width gradually tapers towards its end. There can be plural coils arranged in the longitudinal direction in a consecutive sequence or overlapping each other, at least one of which is tapered towards an end.
