Abstract: A computer contains a CPU with a memory and keyboard. This memory allows information to be entered from the keyboard while a memory with the CPU allows the system to be initialised every time it is used. A user types in personal information via the keyboard and the computer accesses a validation circuit which analyses the time period characteristics of the typed information. The validation circuit may comprise a microprocessor. A gauge is formed from repetitive typing of the same information and then subsequent typed information timing is compared with it. The bus allows communication with disc and video controllers and with a security controller which only gives access to information if the user identity is validated.

Abstract: A process and an apparatus in black-liquor evaporation for the selective removal, by liquid absorption, of hydrogen sulphide from the generated gas (3) containing hydrogen sulphide as well as carbon dioxide, are disclosed. In the process, the gas is countercurrently brought into multistage contact, preferably comprising three stages (6, 7, 8), with circulating carbonate-containing alkaline solutions, preferably sodium carbonate solutions (25), the pH of which is adjusted during the absorption to about 9-12 by the addition of a hydroxide, preferably a sodium hydroxide solution (26, 27, 28).

Abstract: The present invention is a method and device for synchronization at OFDM-systems. A signal is read into the synchronization block in the time domain, i.e. before fourier transforming of the signal via the FFT-processor, according to Figure 1. In the synchronization block the frame clock for start and input of data in the FFT-processor is regained. For OFDM-reception it is very important that this input starts at the right point of time to make possible detection of data. The point of time for the input to the FFT-processor is therefore adjusted in relation to the regained frame clock. When the frame clock has been regained the frequency error can be estimated, which is also performed in the synchronization block. The frequency error is utilized in a control loop for feed back to an oscillator which generates a complex rotating vector which is multiplied by the input signal for compensation of the frequency error. The invention can be utilized at OFDM-system with guard space or OFDM-system with pulse forming. <IMAGE>
