Title: Echo cancellation
Inventor: LING FUYUN
IPC: H04B3/23
Filed: 1988-06-30
Granted: 1994-10-11
Abstract: Abstract of the Disclosure Echo cancellation to remove, from a locally received data communication signal, an echo signal component having a changing phase difference relative to the phase of a locally transmitted data communication signal, said locally transmitted communication signal are generated by modulating a carrier based on sequences of complex data signal points, is accomplished by correcting the phase of an input sequence of complex samples of the modulated carrier based on the changing phase difference to generate complex phase corrected samples, and generating a real-valued simulation of the echo signal based on the complex, phase corrected samples.  Another aspect is estimating the phase difference between two signals based on samples of the real signal component of one of the signals, and the real component of the difference between the signals; successive estimates of the phase difference are generated based on successive applications of an approximate Hilbert transform to samples of each of the real signal component of one of the signals, and to the samples of the real component of the difference between the signals , each application of the Hilbert transform being limited to two of the samples.  Another aspect is averaging a succession of sample values and scaling the result of the averaging in accordance with a variable scaling factor; the succession of sample values is accumulated as a cumulative sample value, and an output indicative of the result is provided by comparing the cumulative sample value with a threshold that is based on the variable scaling factor.

Abstract: ABSTRACT OF THE DISCLOSURE      A digital compass (20) has a sensing coil (60) wound on an elongated strip of high direct current permeability magnetic material.  The sensing coil (60) is connected to a sensing circuit  (56).   The sensing coil and sensing circuit are responsive to the Earth's magnetic field to provide an oscillating signal at an output (28) of the sensing circuit  (56)  which  varies  in  frequency  with orientation of the at least one sensing coil  (60) with respect to the Earth's magnetic field.  A microprocessor (36) is connected to receive information inputs from the oscillating  signal. The  microprocessor  converts  the information inputs to an indication of orientation of the sensing coil with respect to the Earth's magnetic field based on the  frequency of the  oscillating signal. A display (52) receives the orientation indication from the microprocessor.

Abstract: ABSTRACT An integrated-circuit (IC) chip having means to prevent or mitigate damage from electrostatic dis-charge (ESD) employing a thick dielectric coating of insulative oxide between the surface of the chip sub-strate and the metallization film used to make contact with regions of the substrate.  At least a portion of this layer is formed at temperatures below 700°C.  The coating is sufficiently thick everywhere that its break-down voltage is greater than the breakdown voltage of any junction in the substrate. This assures that the break-down caused by ESD will always occur in the junction, which is self healing, rather than in the dielectric coating, where the damage could be permanent.

Abstract: METHOD AND SYSTEM FOR AUTHENTICATION            Abstract of the Disclosure An entity such as a smart card includes microprocessor means, input/output means, and PROM storage means which stores a set of transformations Si  (i=l, .... n) of a corresponding set of public factors Fi (i=l, ..., n), where Si = Fid (mod N), d being the secret key counterpart of a public key e associated with the modulus N, which is the product of two primes.  An authentication device which stores the public factors Fi and the values of N and e, generates an n bit random vector v = vi which is transmitted to the card where a product Y of the values Si selected according to the 1 bits of v is computed and transmitted to the authentication device which computes Xact = ye (mod N) and also computes Xref, the product of the Fi selected according to the 1 bits of v.  If Xact and Xref are equal, then the card is authenticated to within a certain probability.  An analogous method is disclosed for certifying messages to be transmitted.  In further embodiments, a higher degree of security is achieved by arranging for the entity being authenticated, or the certifying entity, to select an additional secret factor or plurality of secret factors.

Abstract: PCT No. PCT/FI86/00124 Sec. 371 Date Aug. 31, 1987 Sec. 102(e) Date Aug. 31, 1987 PCT Filed Oct. 28, 1986 PCT Pub. No. WO87/02616 PCT Pub. Date May 7, 1987.The invention relates to a multi-ply wood product. The supply of wood suited e.g. for the production of plywood has considerably decreased. Consequently, attempts have been made to compensate the deterioration in the quality of the surface finish and in other wood qualities e.g. by means of various coating methods, with varying success. The most important problem has been the insufficient adhesion between the coating and the wood. For the elimination of these problems, a multi-ply wood product has been developed in which at least one layer is formed by a crude fiber ply blank comprising haphazardly oriented fiber material as well as bonding agents, additives and filler materials. A single hot-pressing step in connection with the production of the multi-ply wood product forms this blank into homogeneous ply (14) which, by virtue of the partial splitting of the fiber structure and the resulting reorientation, which take place during the hot-pressing, fills the irregularities in the surface of an adjacent wood layer (1) and forms a tight synthetic ply of accurate dimensions.

Abstract: In an automatic aspirator-transfer valve controlling the delivery of washing fluid from a supply (M) to a cleaning gun (B) and having a valving piston (2) movable between a first or rinsing position, in which it opens bypass conduits (15) bypassing an injector (3,21,4) and a second or washing position in which it closes said bypass conduit (15) and enables the injector (3,21,4) to aspirate washing fluid from a reservoir (not shown) through a non-return valve (11), a side inlet (5) and a conduit (22) to its side inlet (21), the novel aspect is that the side inlet conduit (22) is separated from the space within the housing bore (20), in which the valving piston (2) can slide. 
<??>In this manner it is avoided that a portion of the washing agent may fill the space within the housing bore (20) and leave the valve in the form of a "plug" when changing from the washing mode (Bottom Figure) to the rinsing mode , thus avoiding both the issuing of dangerously high concentrations and unnecessary waste of washing agent.

Abstract: A process for the manufacture of monopotassium phosphate of a high purity without utilizing organic solvents. Monopotassium sulfate is reacted, at a temperature in the range of 40 to 100 DEG C with a phosphate constituent selected from phosphate rock, dicalcium phospate or mixtures thereof in the presence of phosphoric acid. The common metal impurities, organic matter and fluorides present in the starting phosphate rock are substantially eliminated, with the calcium sulfate resulted thereto. After separating out the calcium sulfate, the filtrate is neutralised to a pH in the range of 3 to 7, with a calcium-containing compound comprising Ca(OH)2, CaO or CaCO3, or mixture thereof. From the filtrate obtained, pure monopotassium phosphate is crystallised out.
