Abstract:
A misfire-detecting system for an internal combustion engine detects a value of the sparking voltage generated by the igniting device after generation of the ignition command signal, determines the duration of a discharge of a spark plug, based upon the detected sparking voltage, and determines whether or not a misfire has occurred in the engine, based upon the determined duration of the discharge. For example, the misfire-detecting system measures the duration of the discharge from the time of generation of the ignition command signal, based upon the detected sparking voltage, compares the measured duration of the discharge with a predetermined time period. When the measured duration is shorter than the predetermined time period, it is determined that a misfire has occurred in the engine.
Abstract:
A misfire-detecting system detects a misfire occurring in an internal combustion engine in such a manner that a value of discharge current is detected when sparking voltage is generated in response to an ignition command signal, the detected value of discharge current is compared with a predetermined current value, and it is determined that a misfire has occurred when a time period over which the detected discharge current value after generation of the ignition command signal is above the predetermined current value is shorter than a predetermined time period.

Abstract:
In a keyless entry system, a CPU in an ECU and a CPU in a remote control key each have an associated memory for storing respective function formulas, which are specified by primary function formula data. With this structure, function formulas used in the remote control key and the ECU can be changed to respective new function formulas. This technique makes it difficult to predict the function formulas used in the remote control key and the ECU, thereby further reducing any regularity of rolling codes generated by the function formulas.
Abstract:
A vehicle system includes a plurality of tire sensors, a plurality of low frequency (“LF”) antennas and an ECU. Each tire sensor is mounted in a respective tire of the vehicle. Each LF antenna is mounted on the vehicle and is configured to transmit an LF field to wake up two tire sensors. The ECU is in communication with the tire sensors, via a receiver, and the LF antennas. The ECU is configured to receive identification signals from the respective tire sensors and to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the respective identification signal matches other received identification signals. The ECU is further configured to store the identification signals in the memory with the identification signals being associated with the respective tire sensors that transmitted the identification signal.
Abstract:
An interferometer for demodulating a differential M-phase shift keying signal includes a PLC type interferometer main body, a heating portion that heats the PLC type interferometer main body, and an intermediate member having a higher stiffness than that of the PLC type interferometer main body, for bonding the PLC type interferometer main body and the heating portion with each other while being sandwiched therebetween. A linear expansion coefficient difference between the PLC type interferometer main body and the intermediate member is equal to or smaller than 4.5×10−6/° C., and a thermal conductivity difference between the PLC type interferometer main body and the intermediate member is equal to or larger than 10 W/mK. A phase of an optical signal flowing through the interferometer is adjusted by using the heating portion and a second heating portion.
Abstract:
A peak factor reduction unit that never allow peak factor reproduction even when interpolation is done in a succeeding stage. The unit detects a local maximum value of amplitude components from an input complex signal and supplies a complex signal that passes a band limiting baseband filter and an interpolation filter to a correction signal generation unit for generating a correction signal used for peak factor reduction and reduces a peak factor of the input complex signal with use of the correction signal generated from an interpolated complex signal.
Abstract:
A vehicle door outer handle system includes: an operating handle formed from a handle main body and a cover covering the outer side of the handle main body; a pair of electrodes; and a circuit board on which a detection circuit is provided for detecting a change in capacitance between the electrodes; the electrodes and the circuit board being housed within the operating handle. The electrodes are patterned on the circuit board, and a ground pattern connected to the detection circuit is formed so as to be disposed at a position offset from the electrodes if viewed through the circuit board.
Abstract:
When a first article is to be delivered to a customer and a second article is to be collected from the customer, first rack components required for delivery of the first article and second rack components not required for delivery of the first article, yet required for collecting the second article, are specified. Delivery procedure and collection procedure of the articles using the specified first rack components and second rack components are instructed to a worksite. Accordingly, delivery and collection of the articles can be carried out by making efficient use of the rack components commonly used for the first article and the second article.
Abstract:
An induction machine used as a power generator for an internal combustion engine, and which generates a predetermined power regardless of a rotation speed of a rotor of the induction machine and the engine. A power P to be generated is controlled so as to be equal to an upper limit value Pmax or less, a lower limit value or more or, equal to a target value Pc. The power generation control is achieved in the following manner. A speed N2 of the rotating magnetic field electrically generated with a three-phase winding of the rotor 1R is controlled in accordance with the mechanical rotation speed N1 of the rotor 1R in order that a relative speed N of the rotating magnetic field generated in the rotor with respect to a stator coil is kept at an upper limit speed Nmax or less, a lower limit speed Nmin or more, or a target relative speed Nc.
