摘要:
A system and a method are presented which reduce the number of times of connection and disconnection of calibration standards in a circuit network measurement device provided with many measurement ports. The circuit network measurement device generally includes a network analyzer and a test set. A calibration port is provided and typically placed in the test set. The calibration port consists of a connector and three standards (open, short, and load impedances) connected to the connector internally by means of a selection switch. The measurement port of the circuit network measurement device is calibrated by using the three external impedance standards. The calibrator is calibrated by connecting the measurement port calibrated at the former step. Other measurement ports are then connected to the calibrator to be calibrated. Because the three impedances of the internal calibrator are automatically selected by a switch of the calibrator, by means of logical control, the number of times the standards are connected and disconnected is reduced.

In a control unit for a vehicle steering system, which controls an electric motor that is used to change a steering angle on the basis of a target route for a vehicle, a turning angle of a steered wheel with respect to a central axis of a shock absorber is set as a steered element angle, and the steered element angle is used in control over the electric motor.

A steering apparatus for vehicle comprises a steering shaft including a first portion connected to a steering member and a second portion connected to steerable wheels; a transmission ratio variable mechanism capable of varying a transmission ratio as a ratio of a steered angle of the steerable wheels to a steering angle of the steering member; and a reaction-force compensation motor for compensating a steering reaction force of the steering member caused by the operation of the transmission ratio variable mechanism. The transmission ratio variable mechanism includes a differential mechanism for differentially rotatably interconnecting the first and second portions; and a differential-mechanism motor for driving the differential mechanism. Both an axis of a rotary shaft of the differential-mechanism motor and an axis of a rotary shaft of the reaction-force compensation motor are aligned with an axis of the steering shaft.

Reinforcement of a system renewability is realized skillfully utilizing properties peculiar to a system. As a result, there is produced such a new effect as to similarly reinforce required specification with respect to copyright protection of a content recorded in a medium for exclusive use in reproduction and a recordable medium. In a system which encrypts information such as a content to record/reproduce the information, design is made so that encryption/decryption processing information differs for a device (software (S/W) main body device) whose main body is software constituted of a recording/reproducing drive of a recording medium and a personal computer (PC), a device (hardware (H/W) main body device) whose main body is hardware integrally containing a drive and data coding/demodulation processing, and the medium for exclusive use in reproduction and the recording medium.

A contents recording and reproducing apparatus performs a record and a reproduce of a recording medium, in which the recording medium records a title key file registering therein at least one title key which encrypts each of plural title contents corresponding to a program video or sound, and title contents encrypted by the title key. The contents recording and reproducing apparatus includes an TKF initializing unit 141 which generates a title key file and records it in the recording medium, a random number generating unit 111 which generates a random number corresponding to each of the plural title key files, and a recording unit 113 which records a plurality of title key files in a DVD medium 140. The TKF initializing unit 141 registers the random number, the TKF random number corresponding to the title key file, and an encryption title key.

A vehicle steering system includes: a steering actuator that imparts a steering force to a steering mechanism of a vehicle; an automatic steering controller that performs an automatic steering control by controlling the steering actuator; a driving state detector that detects a driving state of the vehicle during the automatic steering control; a threshold value setting unit that variably sets a threshold value for permitting an intervention in the automatic steering control; and an automatic steering intervention unit that intervenes in the automatic steering control based on a threshold value set by the threshold value setting unit.

An electronic device includes a main body, a drive mechanism configured to move the main body, a detector having a plurality of sensors mounted in the main body for detecting distances to an object which is present in a space around the main body, a calculator configured to calculate a direction of the object relative to the main body based on the detected distances, and a controller configured to control the drive mechanism to change an orientation of the main body dependent on the calculated direction.
摘要:
An automatic parking control is cancelled when a motor current has not yet reached a maximum current value Imax with a steering angle deviation exceeding a deviation threshold value. In addition, the automatic parking control is cancelled when a steering speed has not yet reached a maximum steering speed with a state where the motor current has reached and remains at the maximum steering speed continuing over a first time period. On the other hand, when a state where the steering speed has reached and remains at the maximum steering speed continues over a second time period, it is determined that there occurs an output shortage of a steering actuator, an automatic parking condition is recalculated, so as to allow the automatic parking continue to continue.
