Title: Photoluminscent determination of impurity concentrations in a semiconductor
Inventor: SHIELDS ANDREW JAMES
IPC: G01N21/64
Filed: 1995-10-17
Abstract: The impurity concentration in a sample of semiconductor material is investigated by using it to form at least one barrier layer in a heterostructure in which a quantum well layer is sandwiched between barrier layers of a higher bandgap semiconductor material compared to the bandgap of the semiconductor material of the quantum well layer. The material is subjected to photoluminescence spectroscopy and the intensity of a lower energy peak in a doublet is determined. This is compared with the equivalent peak height from other samples to determine relative impurity concentrations. To obtain an absolute value of impurity concentration, the peak intensity is compared with that obtained from a calibration sample of known impurity level.

Patent GB-2328585-A (GB)
Title: Using Advanced Positioning System for Paging in a Cellular Communication System
Inventor: MONTOYA ALEXANDER JOHN
IPC: G01S5/00
Filed: 1998-02-03
Abstract: An advanced positioning system is used in combination with a cellular communication network to improve the performance of the network. The network includes a mobile switching center (MSC), a location tracker system (LTS), and a plurality of base stations for serving at least one mobile unit in the network. The LTS is able to receive a location code from the mobile unit that represents a specific coordinate, or location, in the network. The mobile unit may have generated the location code by analyzing its position from a global positioning satellite, or by other means. The LTS stores the location code in a data base. Whenever the MSC needs to communicate with the mobile unit, it queries the database of the LTS to determine the last location of the mobile unit. The MSC then selects one of the base stations that serves the location of the mobile unit and establishes a cellular link therethrough.
Patent GB-2334641-A (GB)
Title: Multiplexed transmission of optical signals
Inventor: ROBERTS KIM BYRON
IPC: H04L7/00
Filed: 1998-02-11
Abstract: Optical signals in an optical communication system are transmitted as a train of optical pulses which are multiplexed to provide a large number of channels. Error correction coding is applied to data carried by the channels using both interchannel coding and serial coding of individual channels. When multiplexed by wavelength division multiplexing, a waveguide array (32) is used as a dispersive device having a characteristic of frequency selectivity which is locked by a monitoring and control system to a set of spectral lines (f 1 -f 7 ) from the single pulsed laser which generates the pulses. In the receiver, clock signals are generated by extracting clock signals from the earliest and latest received channel signals and performing interpolation to obtain clock signals for the remaining channels. When multiplexed using a spectral modulation technique, individual channels are represented by distinct sinusoidal modulations in frequency space which are then detected in the receiver by Mach-Zehnder filters (73). When using either method of multiplexing, a receiver has a greater number of detectors than the number of channels to be detected to allow detection to accommodate systematic drift in parameter values of the measurable parameter associated with each channel. Error detection coding is used in each channel as a basis for selecting channels to carry a first data stream, the remaining non-selected channels being used to carry a second data stream in which data may be transmitted at a lower rate suitable to the error rate performance of those channels or alternatively data may be replaced by an error detecting code to continue monitoring error rate performance.

Title: Imaging arrangement
Inventor: RICHES MARK JOHN
IPC: G02B13/16
Filed: 1999-02-15
Abstract: An apparatus for providing a plurality of images from one input image includes a reflecting tunnel 14. All image 10 is conditioned for input to tunnel 14 by an objective lens 12 and an output objective lens 16 focuses the plurality of images onto an appropriate plane 18 such as an electro-optic device. A cross-section of the tunnel comprises four reflecting surfaces 14.1, 14.2, 14.3 and 14.4. Two or more such planes may be provided but each reflecting plane must be orthogonal to any adjacent reflecting planes. Internal reflection within the tunnel 14 splits the images to the required number (in this case nine images are shown). The invention also provides a method by which the apparatus is designed and manufactured. Increasing the length of the tunnel increases the number of images in the array e.g. L3 gives a 3x3 array, L7 gives a 7x7 array - see Fig 10.

IPC: G11B23/26
Filed: 1999-03-24
Abstract: A tape drive wherein a tape leader 30 from a tape cartridge 20 is urged through a tape path 62, into a take-up reel 45, and secured therein without the use of a buckling mechanism or a take-up leader. The take-up reel includes a locking slot defined along the central hub 46 for receiving and locking the leader thereto. As the tape cartridge is inserted into the tape drive, an idle roller 42 moves into position to push the leader against a motorized roller 41, pinching the tape leader therein between. As the motorised roller rotates, friction between the leader and rollers urges the leader through the tape path and into the take-up reel locking slot A slight predetermined rotation of the take-up reel secures the leader with a locking member further defined within the locking slot.

Title: Chucks and methods for positioning multiple objects on a substrate
Inventor: SUN HOI CHEONG STEVE
IPC: B23B/
Filed: 1997-04-09
Abstract: The present invention relates to chucks and methods for positioning multiple objects, optionally for transport onto a recipient substrate. Instead of using conventional clamps that employ mechanical force, the present invention is directed to the use of a non-mechanical force such as negative pressure in a vacuum chuck, or static electricity in an electrostatic chuck as the force applied to the object held by the chuck. Further, the chuck has a layer (430) for holding the objects which are optionally subsequently transferred to a recipient substrate the layer (430) having a configuration substantially corresponding to the configuration of the recipient substrate. In certain aspects, the present invention is directed to a chuck for positioning objects with an average width or diameter less than or equal to one millimeter, and a thickness preferably less than about 3 millimeters, such as beads used in the chemical industry. In another aspect, the invention is directed to methods which involve the use of chucks, including methods for attracting an object (450) or multiple objects, methods for positioning objects, methods for transporting objects, preferably substantially simultaneously, and methods of chemical manufacturing using the chucks.
