Title: In-situ optical measurement of semiconductor physical characteristics
Inventor: GRIFFITHS CARL LYNDON
IPC: G01N21/84
Filed: 2006-05-13
Abstract: Reflectometry apparatus and method for gathering meaningful reflectance data indicative of one or more characteristics of a substance being grown within a reaction chamber in real time during growth. The apparatus includes a light source 30 disposed to the outside of said reaction chamber 32 which includes a substantially horizontal substrate 42 inside the chamber on which the substance growth occurs, and a detector 30 capable of converting light into electrical signals. Light impinging on the substrate from the source is substantially reflected directly towards the detector. During operation, the substrate is periodically, and usually continuously rotated (with constant angular velocity) about an axis substantially normal to the growing plane within said reaction chamber to ensure uniform deposition of said substance thereon. The reaction chamber 32 is provided with operable shutter means 38 disposed between an opening 36 in said reaction chamber and said light source 30 to permit light through said shutter and said opening when said shutter is open but preventing such when the shutter is closed. Ideally, the shutter 38 is caused to open in synchronicity with the speed of revolution of the substrate 42 such that substantially the same discrete area of the substance growing on the substrate is illuminated so as to eliminate the effects of precession on the measurements.

Title: Shower head electric safety valve
Inventor: HARLOW TIMOTHY NEAL
IPC: B05B1/18
Filed: 2008-03-25
Abstract: A shower head has a water inlet passage 24, a spray outlet and a waste outlet passage 25. An electrical temperature sensor 16 and an electronic control system 27 controls an electromechanical valve 26 to open or close depending on predetermined upper and lower sensed operating temperature limits. The shower head may be capable of reacting very quickly to prevent the spray being under or over temperature, thus avoiding extremes of water temperature being experienced by a user of the shower.

Title: Vector perturbation multi-antennae multi-user communication using a power scaling matrix
Inventor: DAO NGOC-DUNG
IPC: H04B7/04
Filed: 2009-02-18
Abstract: The invention concerns power allocation method in a multiple input multiple output (MIMO) system employing precoding. Information for transmission is represented by a data vector, d, comprising corresponding data for each of the multi-antennae. A perturbation vector, 1, is applied to the data vector in order to generate a perturbed data vector, s, (see e.g. equation 22). A power scaling matrix (e.g. GN, equation 16) is used in the computation of the perturbation vector (see e.g. equation 20). The power scaling matrix is preferably a diagonal matrix representing at least the noise power of each receiver. In one embodiment, the invention enables a check to be made, prior to transmission, to determine whether a scheduled multiantenna transmission can be provided with a level of transmit power which is sufficient and also lies below the maximal level of the system.
