Title: Assessing channel impulse response in transmission channel - allowing any series as periodic continuous assessment series in preamble and processes through correlator and correction filters
Inventor: BRAKEMEIER ACHIM DR ING
IPC: H04L25/02
Filed: 1991-11-26
Abstract: The method of assessing channel impulse response in a transmission channel involves transmitting a predetermined periodic continuous assessment sequence at the receiver. The received signal is sampled and correlated in a correlation filter. The output signal (gj) of the correlation filter is multiplied with a correction matrix (fij) in a correlation filter bank. From this, the impulse response of the channel is determined to be equal to the sum from i to j of the output signal multiplied by the correction matrix. ADVANTAGE - Channel impulse response can be accurately determined. Impulse response length is shorter compared to periodic length of sequence.

Title: Coating sensor for chemical or medical analysis - has selectively permeable polymer membrane of adjustable thickness, solubility and diffusion properties or pore properties, giving specified cut=off mol.wt.
Inventor: HINTSCHE RAINER
IPC: G01N27/40
Filed: 1992-04-18
Abstract: In coating sensors with selectively permeable polymer membranes, a firmly bonded layer of at least one organic polymer is applied to a solid sensor surface, and predetermined cut-off properties are achieved by adjusting the thickness of the polymer layer and/or the solubility/diffusion properties and/or the pore properties.

Inventor: OHSAWA YUTAKA
IPC: G03B15/00
Filed: 1992-05-21
Abstract: An exposure zooming operation control device is disclosed having a power zoom lens controlled by a motor 43. An exposure value Ev is obtained based on a result of photometry, and the power zoom lens is driven in an electric mode in accordance with a program diagram proper for a zooming during an exposure. In the program diagram, the shutter speed is set between 1/15 through 1/4 second, which is slower than a usual shutter speed, but when the exposure value obtained by photometry is too large or too small, the aperture value is set to the maximum value or the minimum value, to thereby determine a proper shutter speed. <IMAGE>

Patent DE-4220274-A1 (DE)
Inventor: JAKLIN HANS
IPC: C04B38/00
Filed: 1992-06-20
Abstract: In reinforced concrete components of high-strength concretes, explosive flaking occurs when stressed in a fire. This can be prevented by providing the concrete of such components with a capillary system, whose substantially linear capillaries have a diameter of at least 3  mu m and a length of at least 5 mm. This capillary pore system can be formed, without impairing the other desired properties of the concrete or mortar, during or after the setting of the concrete or even only under the conditions of the fire stress. This is achieved by means of fibres which form the capillaries by dissolution, softening, shrinkage, decomposition or melting and correspond to the desired capillaries with respect to diameter and length as well as the quantity introduced. Supports produced from such fibre concrete, if appropriate with addition of finely disperse silica, can be classified in fire resistance class F 180-A.
