IPC: G10L19/12
Filed: 1992-12-04
Granted: 1996-01-16
Abstract: An optimum excitation signal for each subframe is determined in a speech coder based on analysis-by- synthesis techniques and operating on frames of samples divided into a number of subframes. The excitation signal includes a shape contribution (innovation) and an amplitude contribution (gain) which are quantized separately. A circuit (IT) for gain quantization includes means (QU) for determining a gain index for each subframe; a comparison logic network (CFR) for detecting the maximum value taken by the gain index in the frame; and means for computing a normalized index for each subframe as a difference between the maximum index and the gain index relevant to that subframe. The coded signal includes the coded values of the maximum index and of the normalized indexes as information on the gain relevant to a frame. <IMAGE>

Patent PT-101629-B (PT)
IPC: E05B47/00
Filed: 1995-01-04
Abstract: The invention is a digital lock that combines mechanical and electromagnetic functions operated by code. The handle 8 is mounted on the square shaft 2 which forms part of the following gear system: when the armature 15, which has the fork 14 on the base, is attracted by the electromagnetization of the inductor 9 it will cause the cam 13 to slide on the square shaft 2 and raise it to engage in the box 11, enabling the functions of closing and opening. If the electrical power fails, the digital lock has an emergency button 18 which allows it to be manually opened from inside the house. Outside the house it will be sufficient to press a keyboard button to activate the power of an auxiliary battery and key in the code. The main use of this digital lock is in dwellings owing to its exceptional security conditions, since, not being key-operated, it does not have a barrel nor any slot or orifice through which any break-in object can be inserted. <IMAGE>

Abstract: A sheetlike environment purifying material comprising (a) particles of a metal and/or a metal oxide, (b) particles of an adsorbent, (c) particles of a thermoplastic resin and (d) an air-permeable fibrous base sheet, wherein the particles (a) and (b) are bonded to the surfaces of the particles (c) via the contacts of particles with each other and the particles (c) are bonded to the base sheet (d). This material can be produced by mixing the particles (a), (b) and (c), a water-absorptive resin (e) and water together to form a homogeneous suspension, making a predetermined amount of this suspension held on the fibrous base sheet (d), and heating the resulting composite in a temperature range from the melting point of the resin of the particles (c) to the thermal decomposition temperature thereof to bond the particles to the fibrous base sheet (d) via the particles (c) through the removal of water. The particles of a metal and/or a metal oxide and the particles of an absorbent are not covered with any thermoplastic resin layer and therefore retain their respective original surface areas and performances to exhibit an excellent environment purifying power. This material is useful as deodorizer, toxic gas remover, and the like.
