Abstract: PROBLEM TO BE SOLVED: To keep the speed of a vehicle and the number of rotation of a driving shaft stably constant. SOLUTION: A power output device 20 mounted on a vehicle consists of an engine 50, a clutch motor 30, an assistant motor 40, a controller 80 and a battery 94. Both motors 30, 40 are controlled by the controller 80 to transmit energy output from the engine 50 to a driving shaft 22. When there is a deviation between the speed of the vehicle detected by a speed sensor and a targeted speed, output energy Pd from the engine 40 is increased only equivalent to energy calculated in accordance with the deviation and the torque of the assistant motor 40 is increased only equivalent to such incremental energy.  The increase of the energy of the engine 50 is so poor in response as to take a time but, in the meantime, the energy required for the increase of tone torque of the assistant motor 40 is covered by discharge from the battery, so that the deviation is quickly cancelled to keep the speed of the vehicle as targeted.

Abstract: PURPOSE: To correctly detect a pitch with an audio signal of a small bit length and to attain correct pitch correction processing by using the pitch. CONSTITUTION: An input digital audio signal of 24 bits is stored in a pitch operation data memory 26 while preserving respective codes as the quadripartite four kinds of sample data. The audio signal of 24 bits is stored as it is in an audio data memory 24. A maximum peak detection circuit 32 detects a maximum value related to the audio signal of a certain pitch detection retrieval section. Based on the maximum value, the relevant data of the quadripartite sample data of eight bits stored in the memory 26 are read out (it is called as bit shift processing), and self correlation is calculated in a pitch detection circuit 28, and the pitch is detected. When the pitch is detected, the audio signal stored in the memory 24 is read out based on the pitch. The pitch correction processing is performed by the read-out control.

Abstract: An electronically controlled wastegate valve is adjusted so that the pressure drop across a throttle in the engine approaches an adaptively generated, desired throttle pressure reserve value. The desired throttle pressure reserve value is based at least in part on a history of the engine load. In the preferred embodiment, the engine speed is used as a surrogate for engine load to determine the desired throttle pressure reserve value. The desired throttle pressure reserve value is preferably pushed downward over time by use of a constant negative gain term in the electronic controller. In this manner, the wastegate control provides sufficient throttle pressure reserve for satisfactory load acceptance when engine load is fluctuating, yet minimizes throttle pressure reserve to improve engine fuel consumption when the engine load is relatively steady. <IMAGE>

Granted: 1998-12-02
Abstract: The invention concerns a procedure for the bleaching of pulp, in which procedure an oxidating bleaching chemical containing chlorine is used. The essential feature of the invention is that the pulp is treated, either in conjunction with or before oxidation, with a lignin-modifying oxidation-reduction enzyme, such as the lactase produced by the white-rot fungus. The oxidating bleaching chemical used in the procedure may be chlorine dioxide or a mixture of chlorine dioxide and chlorine gas. The use of said enzyme reduces the amount of chlorophenols and other forms of organically bound chlorine in the spent bleach liquor, simultaneously lowering its chemical oxygen demand.

IPC: A61B5/11
Filed: 1986-10-31
Abstract: A method and apparatus for monitoring means and for detecting motion in the vicinity of the apparatus, particularly a non-invasive cardio-­pulmonary activity, is disclosed comprising an electrostatic charge detector (10) for providing an output signal including signals indicative of motion, e.g. cardio-pulmonary activity of a person in the vicinity of the detector. A detection apparatus (Figure 2) is connected to receive the signals and to filter the extraneous noise signals from the signals of interest to provide output signals indicative only of the motion of interest of cardio-pulmonary activity of the person. Breathing signals are applied to a comparator (66) which is tripped if breathing occurs at a rate below a predetermined value. Cardiac signals are applied to a circuit which adjusts the trip level for the breathing rate if the cardiac rate declines to a level suggestive of brady-­cardia without breathing rate increases. The filtering circuit for the signal supplied by the charge detector incorporates a dual integrator (24) operating as a frequency selective charged amplifier which is effective to substan­tially eliminate all signals outside of the range of about 0.1 to 15 Hz.

Abstract: A method for transmitting signaling and control information for wavelength-division multiplex networks for optical, fiber-bound information transfer in digitized form, the signaling and control information being transmitted via the same optical channel, particularly with the same wavelength, as the useful information, but being encoded and decoded independently thereof, with the result that the control and signaling information can also be accessed independently of the useful information. The use of a time-division multiplex method allowing the different encoding of useful information and control information makes it possible considerably to reduce the technical complexity of passive optical network elements with regard to the routing of the signaling and control information. This method permits the simple, low-cost and transparent transmission of signaling and control information in the optical WDM network.

Abstract: A cryptographic system creates a key table from a single key such that the relationship between the keys in the key table cannot be determined even if the system implementation is known. The system uses variable functions in which the determinants are changed by the variable function chosen by the determinant. Thus, the functions used in creating the key table do not have to be one-to-one functions. From the key table, four blocks of bytes of additional key based determinants are formed which are called masks. The original key does not exist in either the key table or the mask table. The system preferably uses the key table in a multiple round encryption process. The keys chosen from the table for a key addition operation are a function of the plaintext, the current state of the ciphertext, and the mask values. Therefore, the order in which the keys are chosen is not predetermined or patterned. The system also selects the other encryption functions, including permutations and substitutions, by the plaintext, current state of the ciphertext and the mask values. The cryptographic system also can include a function referred to as the enclave function. This function operates on lookup tables and creates complete inter-symbol dependency on the block of bytes.
