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 method of improving energy determination of a Gamma event which interacts with a segmented scintillation detector, the method comprising: identifying radiation events detected by a detector that are likely not to have deposited their full energy in the detector, based only on characteristics of said detected events; and treating the identified radiation events differently from other radiation events that are likely to have deposited their full energy in the detector.

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.

To provide a lateral steady acceleration simulation system for railway vehicle, which is capable of simulating a situation in which lateral steady acceleration is applied to a railway vehicle for a long period of time, while having a compact structure. In a riding quality simulation system of the invention, a control unit activates each of actuators (40), thereby making a simulated passenger room (10) roll. Then, the simulated passenger room (10) is gradually inclined, while a component force, along an inclined plane, of gravitational acceleration g, that is, a first reproductive acceleration G1 is generated depending on an angle of inclination θ. In this manner, a person riding on the simulated passenger room (10) bodily senses the first reproductive acceleration G1 by the roll. At the same time, the control unit moves the simulated passenger room 10, by means of a laterally moving device, in either of the left or right direction with acceleration G. In this manner, the person riding on the simulated passenger room (10) bodily senses a second reproductive acceleration G2. As a result, the person riding on the simulated passenger room (10) bodily senses a combination of the first and second reproductive accelerations G1 and G2 as lateral steady acceleration on a railway.

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.

The power steering device is configured to: apply a required assist force only from a first electric motor until a predetermined period elapses, which is a period from a time point at which a driver starts steering to a time point at which a second-electric-motor drive start condition, which is a condition for starting drive of a second electric motor, is satisfied; when the predetermined period has elapsed, apply the required assist force from the first electric motor and a hydraulic actuator; and adjust an assist force by the first electric motor so that the assist force by the first electric motor is a value obtained by subtracting an assist force by the hydraulic actuator from the required assist force. As a result, the device can be downsized, and a sufficient required assist force can be generated from an initial stage of the steering.

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.

The laminated body is compressed at the temperature at a predetermined pressure. The first metal foil is bonded to the pre-preg sheet of the laminated body and hardening the resin, thus providing a circuit board. 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.
