A diagnosis assistance device assists a diagnosis, by using a plurality of sets of biological information that are measured from a subject, and that are stored in a storage medium. The diagnosis assistance device includes an achievement status determining section and a notification processing section. The achievement status determining section determines an achievement status of a predetermined condition related to biological information that is measured from the subject, based on the plurality of sets of biological information stored in the storage medium. The notification processing section performs a process of notifying of the achievement status. The condition is that the pattern of a change of biological information which is stored in the storage medium contains, threshold or more times, a specific pattern. The specific pattern is extreme-dipper, non-dipper, or riser.

A biometric information measurement device intermittently measures biometric information from a living body. The device includes an attachment and detachment determining section which determines whether the device is in an attached state where the device is attached to the living body or an unattached state where the device is detached from the living body, a personal identifying section which, in the attached state, determines whether a user attached with the device is a registered user who is registered in advance and stores a result of the determination, and a storage controller which, when a determination result indicating that the user is the registered user is stored, stores information indicating the registered user while being associated with the measured biometric information. The personal identifying section deletes the determination result when a time period in which the device is determined to be in the unattached state exceeds a predetermined time period.

A diagnosis assistance apparatus acquires a predetermined period's worth of biological information measured from a living body every heartbeat, from a storage unit storing the biological information, divides the biological information into multiple segments, generates fluctuating state information indicating the fluctuating state of the biological information in each segment, and displays a graph indicating the fluctuating state information of each segment on a display unit. Furthermore, if a certain piece of fluctuating state information is selected in the graph displayed on the display unit, the diagnosis assistance apparatus displays a graph indicating the biological information belonging to the segment corresponding to the selected piece of fluctuating state information on the display unit.

A controller applies slight rotational torque to a drive gear of a reduction mechanism also in a predetermined range in which a motor does not produce any steering operation assist force. That is, the motor is caused to produce slight rotational torque not enough to drive a driven gear, and the rotational torque direction is reversed under a given condition. Accordingly, a backlash between the drive gear and the driven gear is eliminated.

Electric power steering system

Apparatus and method for extracting from a moving image a scene in which an intended person appears by simple operations are provided. A moving image editing apparatus identifies a person as an extraction target based on an instruction of a user, tracks a face of the extraction target to thereby select a scene in which the extraction target appears in a moving image, and extracts a partial moving image containing the selected scene from the moving image.

There is provided a vehicle steering system which includes an electric motor for imparting a steering force to a steering mechanism of a vehicle and an automatic parking controller for executing an automatic parking control by controlling the electric motor, wherein the automatic parking controller controls an energizing voltage of the electric motor by imparting a square wave to the electric motor and increasing/decreasing a neutral point voltage of a winding of the electric motor.

Vehicle steering system

In a steering-without-driving state, a larger current limit value, drive limit time and steering angle deviation threshold value are set than when a low-speed driving state occurs. An automatic parking mode is held until a time period over which a state where a motor current value of an electric motor which drives a steering mechanism is equal to the current limit value reaches the drive limit time. Even though the state where the motor current value is equal to the current limit value has continued over the drive limit time, the automatic parking mode is held during the steering angle deviation not exceeding the steering angle deviation threshold value. When the state where the motor current value is equal to the current limit value has continued over the drive limit time Ta and that the steering angle deviation exceeds the threshold value, the automatic parking control is cancelled.

A brake application speed is compared with a speed threshold value so as to judge whether or not a braking operation being performed is an emergency braking operation. If not the emergency braking operation, an automatic parking mode is held. When the emergency braking operation is in effect, control information related to a state of an automatic parking control then is stored in a control information storage section, and the automatic parking control is cancelled. Thereafter, when a steering operation or a gearshift operation is performed before a cancellation of application of the brake is detected, the process is ended, and the control mode is held in an assist mode. When the application of the brake is cancelled with neither the steering operation nor the gearshift operation performed, the control information is read in so as to resume the automatic parking control.

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 automatic parking control is cancelled when a motor current has not yet reached a maximum current value Iwith 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.

The method and apparatus for detecting maximum and minimum values, and the torque detecting apparatus and steering apparatus comprising the maximum and minimum values detecting apparatus can detect maximum and minimum values of detection signals without setting a particular value such as a threshold. A signal processing unit provided at the maximum and minimum values detecting apparatus detects a crossing of two detection signals outputted from two MR sensors, and detects maximum and minimum values of the signals based on maximum and minimum values of the signals detected within a time interval defined by the time when a crossing is detected.
