Abstract:
The present invention relates to a variable rigid structure comprising multiple elastic members formed with elastic material which is easily deformed elastically and multiple rigid members formed with a material more rigid than the elastic material. The variable rigid structure comprises an operational assembly where the elastic member and the rigid member are alternatively arranged and a cable hole, which is penetrating the elastic member and the rigid member along the arranging path of the elastic member and the rigid member, is formed; and a cable having one end fixed at one end of the operational assembly and the other end extended to the other end of the operational assembly by passing through the cable hole of the operational assembly for elastically modifying the elastic member of the operational assembly according to the tension mounted from outside.

The present invention relates to grip supplementary gloves using a detachable magnet for gripping pens or spoon and chopsticks with hands when a user cannot easily handle his/her hands or have no power in fingers due to old age or disability. The grip supplementary gloves of the present invention comprise 8 magnets: magnets (10, 11) that connect the thumb and middle fingers; magnets (20, 21) that connect the thumb and index fingers; magnets (30, 31) that index and middle fingers; and magnets (40, 41) that connect the gloves and tools. One (41) of the magnets is attached to a pen (60) or spoon and chopsticks, and other 7 magnets are attached to the gloves (50). Thus, even if a pen or spoon and chopsticks are changed, the grip supplementary gloves accordingly determines the contact points and makes supplementary grip possible by using magnets at each contact points.

PURPOSE: A method for detecting the displacement of a shape memory alloy (SMA) coil actuator, and an actuating device and system using the same are provided to detect the displacement of the actuator based on an inductance value from the actuator. CONSTITUTION: A method for detecting the displacement of a shape memory alloy (SMA) coil actuator includes: a step (S10) of detecting the steady state voltage (V-steady) and steady state current (I-steady) of the actuator to which a pulse width modulation (PWM) voltage signal is applied; a step (S20) of detecting time (tnτ) for reaching to a current value corresponding to nτ with analyzing the transient response of a current flowing in the actuator; a step (S30) of detecting the inductance (L) of the actuator using the values of the detected V-steady, I-steady, and tnτ; and a step (S40) of detecting the displacement of the actuator using the value of the inductance and a pre-stored corresponding relation between the inductance and the displacement. In the step of detecting the tnτ, the τ is a time constant, and the n is an arbitrary number.
