Granted: 2009-04-02
Abstract: The application relates to an in-situ method to measure and adjust the sound signal presented to the eardrum by means of a hearing aid and a hearing aid employing such a method. The hearing aid comprises microphone (1), signal processing system comprising digital signal processor (2) for transforming the microphone signal into a transformed signal according to a desired transformation function, sensor (4) sensing the sound signal appearing in front of the eardrum and comparator (5). Reference signal processor (6) generates a reference signal based on the output of microphone (1) and representative of the desired sound signal in front of the eardrum. A transfer function between receiver (3) and the output of sensor (4) is established to correct the process in reference signal processor (6). The sound signal in front of the eardrum is sensed, fed back and compared in said comparator (5) with said reference signal. In the case that the difference between the sensed signal and the reference signal is above a predetermined threshold the transformed signal is corrected to adjust said signal in front of the eardrum to the desired sound signal.

Abstract: A anonymous decryption system, the management of which is facilitated and initialization of which is readily and reliably carried out. A shuffling management center (10) transmits a security parameter and common public information generated on the basis of the security parameter to decryption shuffle centers (20-1 to 20-m). The decryption shuffle centers (20-1 to 20-m) generate public keys and decryption keys and returns the public keys to the shuffling management center (10). The shuffling management center combines the returned public key to generate an encryption public key and make the encryption key public. The shuffling management center (10) repeats transfer of encrypted data list to the decryption shuffle center (20-j) having the j-th processing priority when it decrypts the encrypted data list, transfer of a received data list of which a order-switching process and a partial decryption process are carried out to the next decryption shuffle center (20-(j+1)). Such processing is carried out for up to the last decryption shuffle center (20-m) and make the data list from there the decryption result. <IMAGE>

Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing at a high productivity a styrene resin which has an improved processability, process stability and mechanical characteristics and contains an extremely small quantity of elusive or volatile matters due to a low content of low molecular components. SOLUTION: This method of manufacturing the styrene resin containing a small quantity of low molecular components comprises a continuous anion polymerization process in which raw materials having a composition (A) comprising 1.0 kg styrene monomer, 0.1-3 kg hydrocarbon solvent and 0.5-200 mmol organic lithium compound are continuously fed collectively or separately through one side of a reaction tank R1 having a back-mixing flow and a product is continuously taken out through the other side of the reaction tank R1. The internal temperature of the reaction tank R1 is controlled in a range of 40-120 deg.C. An average percentage of a styrene monomer to a total of the monomer, hydrocarbon solvent and a styrene polymer in the tank R1 is controlled to less than 10 wt.%. A styrene polymer solution thus obtained is evaporated and dried.

Abstract: A system for assisting a user in selecting a packet-based telephony service provider ("PBTSP") from a group of PBTSPs, and in registering the user with the selected PBTSP for outbound and/or inbound calling. The selection of a particular PBTSP may be stored in a database, and this stored information may be used to enable the user to exchange telephone call data with one of the PBTSPs. One preferred system receives data from the user's computer device, determines whether the user is registered with one the PBTSPs and, if so, transmits data to the computer device which enables it to exchange telephone call data with one of the PBTSPs. The system also receives telephone call data from the computer device, accesses contact information for a PBTSP, and transmits the received telephone call data to the PBTSP using the accessed contact information. <IMAGE>

Abstract: A secondary station has a receiver capable of resolving signals received (504,510) as a plurality of multipath signals from a plurality of base stations during a soft handover process. In order to decode and act upon the received signals in a very short period of time, an initial subset of received multipath signals is processed (506) to provide an estimate of the action needing to be taken by the station, which action is then implemented by the station (508). Later arriving signals are processed separately (512) and used to update the estimate, as a result of which the action already taken may be corrected (514). Such a secondary station is particularly suitable for decoding and acting upon power control commands included in received signals in a UMTS system, for which a very limited period of time is provided by the UMTS specification.

Abstract: The present invention expands a spinal canal by drilling a cylindrical passage in each pedicle of a vertebra, making a circumferential pedicle cut (osteotomy) through each pedicle from within the passage, separating each pedicle cut by inserting an implant into the passage which distracts the pedicle cut to expand the spinal canal, and securing each pedicle cut, allowing the vertebra to heal with the spinal canal expanded. The implant includes an outer sleeve, an inner bolt, and expandable flanges. The outer sleeve includes an upper portion and a lower portion, with the expandable flanges connected to the lower portion and housed within the upper portion. Rotation of the inner bolt causes the upper and lower portions of the outer sleeve to separate, causing the pedicle cut to widen and the expandable flanges to radially extend into and stabilize the widened pedicle cut to effectuate expansion of the spinal canal.

Abstract: The invention relates to a method for a high temperature short-time distillation of residual oil. The method according to the invention is characterized by a technically simple recovery of a small residual fraction from a gas and/or oil vapour mixture produced by a mixing apparatus (1). Said small residual fraction contains large quantities of undesirable polluting catalytic substances (CCR, Ni, V, asphaltenes). For this purpose, the gas and/or oil vapour mixture produced by the mixing apparatus (1) is diluted with gas or water vapour in a column (17) at a temperature of 450° C. in such a way that a high boiling fraction, which has a high content of the pollutant substances and whose initial boiling point is higher than 450° C., is condensed and extracted. Another realization of the method consists in introducing a non condensed oil produced in the column (17) into a fractionating column (19), where said oil is decomposed in order to produce a depressurized gas oil fraction having a low content of pollutants and a benzine/gas oil fraction.

Abstract: In a WDM type PON system, each ONU comprises an optical transmitter capable to transmit optical signals with variable wavelengths, an optical signal receiving filter variable its receiving wavelength, and a control unit. An OLT selects in response to a wavelength allocation request from each ONU, a transmitting wavelength and a receiving wavelength out of currently free wavelengths and allocates these wavelengths to the requester ONT. The control unit of the ONU switches the transmitting wavelength of the optical transmitter and the receiving wavelength of the optical signal receiving filter to the wavelengths specified in a response message from the OLT and starts data communication.
