Abstract:
When a knob is turned by a predetermined turning angle null and this angle is detected by a rotary encoder, an electromagnetic brake is activated by a controller and the rotation of the knob is locked. Then, while the knob is locked by the electromagnetic brake, the controller determines whether an operating force was applied to the knob in direction A in which the turning angle of the knob is increased. If the controller determines that the operating force was not applied to the knob in direction A (if the operating force was applied in direction B), the locking of the knob is released.
Abstract:
A force sense imparting type input apparatus includes an operation portion, an actuator for imparting a force sense to the operation portion, a position sensor for detecting an operating direction and an operating quantity of the operation portion, a temperature sensor for detecting a temperature of the actuator, and a controller for acquiring a position signal and a temperature signal and outputting driving signal of the actuator. A correction control portion provided to the controller determines a calorific value of the actuator from the temperature signal, then a correction value of driving power supplied to the actuator from the calorific value so calculated, adds a correction value of driving power of the actuator at the time of a normal operation and decides driving power of the actuator at the time of over-heat.
Abstract:
The motor driving apparatus comprises a plurality of motors 11 to 14 for displacing the position of the control object member, semiconductor switch pairs 4 to 8, a plurality of motor driving units 21 to 23 for connecting the motors 11 to 14 to the power supply and a control unit 3 for ON/OFF controlling the semiconductor switch pairs 4 to 8. The motors 11 to 14 form two sets of motors with each set being formed of two motors. One end of the motors 11 to 12 and 13 to 14 forming each set is connected to the common motor driving unit 23 having the semiconductor switch pair 8 and the other end of the motors 11 to 12 and 13 to 14 forming each set is connected to the motor driving units 22, 23 having the semiconductor switch pairs 4 to 5, 6 to 7 in each set. When the motors 11 to 12, 13 to 14 of each set are driven simultaneously, the control unit 3 turns ON and OFF two semiconductor switch pairs 4 to 5, 6 to 7 and drives the motors of each set 11 to 12, 13 to 14 on the time division basis to provide inverse output polarities of the two semiconductor switch pairs 4 to 5, 6 to 7 connected to the motors 11 to 12, 13 to 14 of each set. Thereby there is provided a low price motor driving apparatus that has reduced the total number of motor driving units 11 to 13 using the motor driving units 21 to 23 having the semiconductor switch pairs 4 to 8.
Abstract:
An image displaying device includes a display unit which displays a cursor and at least one button; an input unit for moving the cursor and for selecting the button; and a controller for controlling the display unit and the input unit. The input unit is provided with an operating part operated by an operator, at least one position sensor which detects an operation state of the operating part, and at least one actuator which applies a specific external force to the operating part. When a display screen of the display unit is switched, the controller drives the actuator to move the cursor to a default position set in the switched display screen. In that case, the moving rate of the cursor is set lower than a moving rate of the cursor for pulling the cursor towards the center of the button.
Abstract:
A force-feedback input device comprising an operating section, actuators to supply force-feedback by way of a transmission mechanism to the operating section, a movement quantity detector to detect a quantity of movement of the actuators and a controller to control the actuators by an output from the movement quantity detector. An initializing process is performed by the controller at startup utilizing an output from the movement quantity detector, and an output to the actuators is compensated after startup so that a fixed quantity of force-feedback is supplied to a quantity of movement of the operating section.
