Title: An optical emission device having quantum wells
Inventor: MARCKS VON WURTEMBOURG RICKARD
IPC: H01S5/183
Filed: 2000-06-20
Abstract: An optical emission device comprises a semiconductor, for example, AlGaAs with conduction and valence bands. A plurality of quantum wells 3 are formed in the conduction and valence bands in a multiple quantum well region 10, such that recombination of holes and electrons between the quantum wells results in the emission of light. At least some of the quantum wells have different characteristic emission frequencies to broaden the gain spectrum of emitted light. The quantum wells 3 with different characteristic emission frequencies may have different widths, or different barrier thicknesses. The optical emission device may be a Vertical Cavity Surface Emitting Laser (VCSEL). The device may include a Distributed Bragg Reflector (DBR). A method of broadening the gain spectrum of an optical emission device is also disclosed.

Title: Inter-network connection through intermediary server
Inventor: SPACEY SIMON ALAN
IPC: H04L29/06
Filed: 2000-08-14
Abstract: Communication between private networks without the need for holes in firewalls of those networks is achieved using an intermediary server located on a public network. A component in the private service network opens one or more outbound connections to the intermediary server and leaves these connections open waiting for a response. These outbound connections pass transparently through any restrictive firewalls on the private service network. A component on the client private network then connects to the same intermediary server with an outbound connection and sends it a request that should be serviced by a server on the otherwise inaccessible private service network. The intermediary server passes this client request on to the private service network as a response to the waiting outbound connection previously opened, unblocked by the private network firewall. The service component reformats the request and transmits it on to the service machine in the private network as required.

In an embodiment the value of power supplied to the main beam discharge lamp may be greater than its rated value, and the value of power supplied to the dipped beam discharge lamp may be smaller than its rated value. In another embodiment the power supplied to one of the lamps is kept lower than the rated power during the transient period after they are switched on. In a further embodiment the period of peak power taken by one of the lamps following switch on is shifted so that it does not coincide with the peak power period of the second lamp.

Title: Colour signal processing which removes illuminant colour temperature dependency
Inventor: FINLAYSON GRAHAM
IPC: G06V10/56
Filed: 2001-01-12
Abstract: Colour component signals from a signal source are processed using an algorithm incorporating a value dependent on the spectral sensitivity of the source. The value may also be dependent on Planck's equation defining back-body illumination. The spectral sensitivity may be determined by illuminating the source with lights of two different colour temperatures T1, T2 and subtracting the component values (R1 - R2, G1 - G2 etc) etc to give values u, v, w etc. The components are processed according to:<BR> <BR> (R*G*B* ...) = (R'G'B' ...) + X(u,v,w ...)<BR> <BR> where R'G'B' are Log values of the components. The technique removes the effect of variable colour temperature illuminants on the output signal and is particularly useful in colour based object recognition and is said to bridge the gap between classical colour constancy computation and the invariant approach.

Title: Method of controlling an electrode force of a spot welding gun
Inventor: KOBAYASHI NOBUO
IPC: B23K11/31
Filed: 1998-02-26
Abstract: In a spot welding gun which is made up of a gun main body 2 which is operated for equalization by a driving source 6, a stationary electrode 3 which is immovable relative to the gun main body 2, and a movable electrode 5 which is connected to a pressing source 4, both electrodes 3, 5 are pressed to a workpiece W with an even force, to thereby perform a high quality spot welding. The driving source 6 is controlled such that the electrode force of the stationary electrode 3, by the driving source 6, to the workpiece W becomes substantially zero. In this manner, there occurs no difference in the electrode forces by both the electrodes 3, 5 to the workpiece W. The driving source 6 is controlled by moving the stationary electrode 3 by means of the driving source 6 to a landing start position which is spaced from the workpiece W by a predetermined distance, and switching a driving force of the driving source 6 to a value which is both necessary and sufficient to support the weight of the gun main body 2, and holding the driving force at that value.

Title: Passive photodetector
Inventor: CHA CHER LIANG RANDALL
IPC: H01L31/105
Filed: 2002-03-08
Abstract: A PIN photodetector includes a detecting section comprising an n-doped layer, an undoped layer and a p-doped layer, the n-doped layer conformally epitaxially grown to form a second n-doped layer continuous with, but perpendicular to, the n-doped layer of the detecting section. The structure of the photodetector thus permits combination of features of both an edge incident photodetector and a surface incident photodetector. The detecting section acts as a surface incident photodetector, while the perpendicularly disposed n-doped layer provides the location for the electrical contacts, as in an edge incident scheme.

Title: Stream cipher encryption system in which a keystream can be extended by concatenating with another keystream to allow encryption of variable length bursts
Inventor: RAYNE MARK WENTWORTH
IPC: H04L9/22
Filed: 2002-06-28
Abstract: Encryption is carried out by combining a block of plain text 6 with a key stream segment 9b generated by key stream segment generator 2 in a bit-wise exclusive-or operation 3. The key stream generating algorithm 2 generates the key stream segment for combining with the plain text 6 using an input initialisation vector 5 and an input encryption key 9a. The encryption key 9a used as input by the key stream generator 2 is itself generated by an encryption key generating algorithm A1, in an encryption key generator 1. A further additional parameter input 9 to the encryption key generating algorithm A1 in the form of a two-bit key segment number KSN, allows additional encryption keys to be produced from the same cipher key input 4. These are then used in key stream segment generator 2 to generate additional key stream segments KSSa, KSSb and KSSc which are appended to the basic key stream segment KSS to encipher or decipher longer (in terms of number of bits) transmission bursts.

Abstract: A cooling jacket for a flashlamp or arc lamp has an outer surface roughened by an etching agent, sandblasting or manual abrasion. This reduces the fraction of radiation generated by a lamp having a cooling jacket and undergoing total internal reflection at the surface, thus increasing the useful optical output power of the lamp. A flashlamp- or arc-lamp pumped laser having a lamp with such a cooling jacket shows improved overall electrical-to-optical conversion efficiency and higher output energy for a given pump energy.
