Abstract: A variable valve timing adjuster with an intermediate lock mechanism learns a lock position and a lock release control. During a lock control, a learning of the lock position from a real camshaft phase is repeated to update the learned value, and the learning is ended when it is judged that the learned values have converged. At this time, when the learned values of the lock position do not converge even if the number of learning of the lock position exceeds a predetermined value, an insufficient lock state is judged, and the learned value of the lock position is set to an initial value or the learned value at the previous lock control thereby to make a lock release control. During the lock release control, on the other hand, the control (or the lock release control) of a hydraulic control valve is learned. When the lock cannot be released during the lock release control, the lock release control (or the learned value) is corrected in a direction to facilitate the lock release. When the correction of the lock release control is repeated a predetermined or more number of times or when the lock release control goes outside a predetermined range, the lock release failure is judged.

Abstract: In a synchronous cellular radio telecommunications network that employs a time division multiple access (TDMA) channel allocation scheme, an effective approach to allocating channels or time slots in a TDMA time frame containing asymmetric downlink and uplink traffic channel fields can be achieved by dividing the downlink and uplink traffic channel fields into a number of regions, based on an expected level of intercell interference associated with each region. In addition, the level of susceptibility to intercell interference for each mobile unit operating in a given cell is continuously established. The allocation of channels or time slots is then carried out for each of the mobile units based on, among other things, the level of susceptibility associated with each of the mobile units, the level of expected intercell interference associated with each of the regions, and whether the channel or time slot is being allocated for the purpose of conveying information in the uplink or downlink traffic channel field. In a synchronous cellular radio telecommunications network that employs a time division multiple access (TDMA) channel allocation scheme, an effective approach to allocating channels or time slots in a TDMA time frame containing asymmetric downlink and uplink traffic channel ...more ...less

Abstract: A portable radio telephone handset operates as a data transfer terminal as well as an analog cellular telephone subscriber station. Two modes of operation, an analog cellular communication mode and a Cellular Digital Packet Data (CDPD) mode, are available in the handset. The handset distinguishes between paging signals indicating CDPD mode communications and those indicating analog cellular communications. The handset also automatically preempts CDPD communications in favor of analog cellular communications such as those carried out in an AMPS configuration. The handset maintains an active status on a CDPD communication channel during a “sleep mode”, when the handset can carry out AMPS activity.

Abstract: In a method for monitoring growth disorder therapy, a magnetic resonance image of a skeletal body portion, such as a hand, of a candidate for growth disorder therapy is obtained using an open magnetic resonance scanner and using an imaging sequence to produce a tomogram having a slice thickness which approximates the thickness of the hand. The number of visible wrist bones and the width of epiphysis joints in the magnetic resonance image is evaluated to obtain osteo age data, and the osteo age data, in conjunction with an atlas of compiled osteo age data, are used to determine the osteo age of the candidate for growth disorder therapy. The relationship between the osteo age of the candidate and the chronological age of the candidate is used to determine whether growth disorder therapy is required. If growth disorder therapy is administered, such as by administering a hormone, the above procedure is repeated after a predetermined time, and the status of the therapy is again evaluated.

Abstract: A method of and apparatus for the treatment of chronic wounds using pulsed electromagnetic energy provides a constant, known and replicable dosage output which remains unaffected by the capacitance of the patient's body. The apparatus is simple to operate, requiring little operator training or interaction with the apparatus. All specifications of the apparatus relating to the generation and emission of electromagnetic energy are fixed, with the specifications based on actual scientific studies of the various technical parameters involved, such as pulse width and RF dosage. The apparatus includes a pulsed electromagnetic energy generator, a power level controller and one or more thin applicators which can be flexible. The applicators are located immediately adjacent to the patient's body, without the aid of a support member or removal of any dressings or bandages. The generator, which can be battery-operated, is a low power, programmable compact unit whose output is controlled by multiple control circuits for ensuring accurate treatment dosage, for confirming that the treatment was properly administered, and for disabling the generator when appropriate. The generator output is automatically adjusted in response to instructions from the field strength sensor located on or near the applicator. Multiple applicators selected to operate simultaneously at different treatment dosage levels are connected to the generator by multi-conductor cables and readily located directly on the treatment area. Each applicator is a pad including etched printed circuits. The circuits are matched and pre-tuned. An applicator-to-patient proximity detector is also incorporated in or on each applicator and connected to the generator via a power controller to provide for direct monitoring of the treatment site and precise control of treatment dosage. A method of and apparatus for the treatment of chronic wounds using pulsed electromagnetic energy provides a constant, known and replicable dosage output which remains unaffected by the capacitance of the patient's body.

Abstract: A hand held applicator for delivery of microwave energy to skin surfaces is provided that is compact, easily manipulated, precisely positionable and secure against malfunction. Microwave energy of a chosen frequency is supplied for a given duration at a predetermined energy level, via one or more waveguides having a distal end section that is dielectrically loaded and matched to skin impedance. Positioning indicia may be disposed on a single use end cap adjacent the emitter end of the applicator to permit easy visualization by the surgeon or technician. Coolant, such as a pressurized gas refrigerant, is supplied in a burst to the skin surface via an interior solenoid controlled valve. The microwave energy pulse is initiated by control circuits after the effective delivery of coolant is sensed. The initiation of the cycle can be effected by actuation of a switch, movement of the applicator against the skin, or by tracking the movement of the applicator from one position to another. Further, two or more microwave energy emitters may be disposed in the same housing in a compact fashion, and arranged to fire serially at the chosen target locations. A hand held applicator for delivery of microwave energy to skin surfaces is provided that is compact, easily manipulated, precisely positionable and secure against malfunction.

Abstract: A shift control method for automatic transmissions includes the steps of outputting a duty control signal for upshifting to a N+1 speed when an N+1 upshifting signal is input during driving in an N speed, pre-estimating a stroke gap of a friction element for the N+1 speed, determining if an N speed kickdown signal is input or not, outputting a duty signal for downshifting to the N speed when the N speed kickdown signal is input. The step of preestimating a stroke gap includes the step of calculating an amount of hydraulic fluid accumulated on a side of the friction element. The step of calculating comprises the steps of calculating an amount of hydraulic fluid with respect to a duty ratio and integrating the calculated amount of hydraulic fluid. A shift control method for automatic transmissions includes the steps of outputting a duty control signal for upshifting to a N+1 speed when an N+1 upshifting signal is input during driving in an N speed, pre-estima
