MIMO transmission methods are applied to communicaiton systems in which a transmitter has more than one transmit antenna and a receiver has more than one receive antenna. Information to be transmitted is divided into a plurality of subsignals according to the number of used transmit antennas and each subsignal is processed separately before it is emitted by the respective transmit antenna. In the receiver the different receive signals are processed thus that subsignals are detected and decoded and the contribution of each detected and decoded subsignal is subtracted from the receive signals and whereby a feedback channel from receiver to transmitter is used to send control information to the transmitter depending on the receive situation. In order to optimize the usage of the MIMO channel the invention proposes the in the receiver the link quality of each subsignal is determined and information of each subsignal is transmitted to the receiver via the feedback channel and that in the transmitter properties of the subsignals are controlled by the link quality information.

The technique of the invention calculates an edge gradient magnitude a(x,y) at each pixel position (x,y) and an edge width w(x,y) from luminance values of an object image, and computes an out-of-focus evaluation value M(x,y) at each pixel position (x,y) from the calculated edge gradient magnitude a(x,y) and edge width w(x,y). The technique then divides the object image into a preset number of blocks, determines a representative out-of-focus evaluation value Y(m,n) in each block, and compares the representative out-of-focus evaluation value Y(m,n) with a preset threshold value for block classification to categorize each block as an in-focus block or an out-of-focus block. The technique eventually determines the object image as in-focus or out-of-focus, based on the total number of blocks included in in-focus block areas, the total number of blocks included in out-of-focus block areas, and the relative positions of the in-focus block areas and the out-of-focus block areas to the whole image.

A detector for detecting radiation, the detector comprising: a plurality of elongate scintillator segments arranged in a side by side array; and at least one pair of light sensors optically coupled to ends of each of the elongate scintillator such that they receive light from scintillations produced in the scintillator and generate electrical signals responsive thereto.

A system and method for responding to a current overload condition in a power switch provides a class D topology that applies a current sink or current source to the gate of the power switch. The current sink or source decreases or increases current flowing through the power switch to regulate power switch output current in the event of an overload. A timer for current regulation can be provided to shut off the power switch if the overload condition persists. A set of differently rated switches can be used separately or together to provide a range of current regulation response, from a wide regulation range with a fast response, to a narrow regulation range with a slow response. The system provides a rapid response to an overload condition and output current regulation without disabling the power switch to overcome short term overloads.

The frequency changes in a bang-bang PLL that are generated using a digital phase detector's up / down signal are initially set to produce a faster pull-in rate and then reduced to produce a slower pull-in rate. The faster pull-in involves relatively large frequency changes and the slower pull-in rate involves smaller frequency changes. The changes in frequency of a bang-bang PLL can be implemented using a step size controller that includes timing control logic and step size logic. The function of the timing control logic is to control the timing of step size changes. The function of the step size logic is to set the step size of the frequency changes that are made by the VCO in response to the pd_up / down signal that is delivered directly to the VCO from the digital phase detector.

A steam turbine driven electric power plant with an electric generator is switchable into an islanding mode wherein a main steam turbine is shut down and a lower capacity industrial steam turbine runs the electric generator instead, to supply house power to the plant while decoupled from the power grid. This avoids operating the main steam turbine and / or its steam source at reduced ratings for which they are not optimized and keeps the plant ready for restarting. The main steam turbine, the electric machine and the industrial steam turbine are mechanically engaged or disengaged through an SSS clutch, torque converter and transmission. In another mode, the electric generator is decoupled mechanically and operated as a mechanically unloaded synchronous motor coupled to the power grid, namely as a synchronous condenser wherein phased over- or under-excitation of the motor field windings supplies reactive power to the grid.

Provide is a wrist type blood pressure meter cuff not oppressing the non-selected artery so as to prevent its pulse waves from mixing into pulse waves of the selected artery necessary for measurement, in a cuff used in a blood pressure meter for measuring blood pressures by selecting and oppressing one artery of the wrist. A wrist type blood pressure meter cuff comprises a fluid bag for oppressing a selected artery of either radial artery or ulnar artery located at the wrist by feeding fluid inside to inflate, and a fixing member for fixing the fluid bag at the wrist. By forming a gap between the fixing member and the wrist, the oppressing pressure directly applied from the fixing member to the wrist at which the non-selected artery is located is set smaller than the oppressing pressure directly applied from the fixing member to other position of the wrist when oppressing the wrist by inflating the fluid bag. This gap is produced by a swollen part provided in the fixing member.

This method provides a stable resistance of a conductive paste filling a through-hole in the pre-preg sheet to be compressed at a small rate.

The present invention is a multiple reaction set for the production of chemicals by equilibrium limited reactions utilizing plate-type or extended surface heat exchangers. The heat exchangers effectively cool the reaction products in order to condense the methanol contained within the reaction products for separation, and also to warm incoming feed reactants prior to entrance of the reactants into a reactor utilized for the production of methanol. The various reactors, heat exchangers, and separators can be formed as separated zones within the enclosed vessels, thereby eliminating the need for separately constructed reactors, heat exchangers, and separators. Multi-stream plate-type of extended surface heat exchangers can be utilized to allow efficient cooling and methanol separation. The multiple reaction set can also be used for the recovery of methanol from a waste or purge gas stream utilizing multiple reactors, multiple plate-type or extended surface heat exchangers and multiple separators as a substitute for or in conjunction with a conventional methanol synthesis loop.

A priority number of each combination of a manufacturing device and a step are first calculated by the equation=processing time×number of processible steps×number of usable devices. From the combination having the smallest priority number (i.e. highest priority), a lot will be allotted to the device for the step. The priority number is updated every after allotment of one lot by the equation=processing time×number of processible steps×number of usable devices×{(device load×10)k+1}. By repeating this procedure, all the lots scheduled to be processed are allotted to the corresponding devices. In addition, in the actual manufacturing process, whenever there is a lot that has to be processed, execution of processing such a lot is directed by successively selecting a device having the lowest accomplishment rate.
