In this study, composite monoliths with porous structures were prepared using quaternized chitosan and diatom earth for protein separation. Quaternized chitosan (N‐[(2‐hydroxy‐3‐trimethylammonium)propyl] chitosan chloride) dissolved in water was mixed with diatom earth and crosslinked with glutaraldehyde under low‐temperature conditions to form a cryogel. Interconnected porous monoliths were obtained...
In the perception-assist, user's dangerous motion is changed to safety motion when there is a possibility of accident such as the collision between user's body parts and obstacles. On the other hand, the joint motion of a human can be changed by using vibration stimulation on the tendon of muscle. By using this motion change method, there is a possibility that perception-assist by using vibration...
This paper proposes a placement algorithm using analytical placement (AP) and low-temperature simulated annealing (SA) for mixed-grained reconfigurable architecture (MGRA) with dedicated carry chains. The target MGRAs are assumed to have fine-grained blocks with dedicated carry chains to implement high-speed adders/subtracters and coarse-grained blocks to implement complicated arithmetic operations...
Both motor ability and sensory ability are important to generate human daily motion. However, owing to ageing and/or physical handicap, these abilities sometimes decline. In order to assist motor ability and sensory ability, lower-limb/upper-limb power-assist robots with the perception-assist function have been proposed. By using the perception-assist function, the user's motion is automatically modified...
In order to assist not only motor function but also perception ability to perceive surrounding environment, a power-assist robot which has perception-assist function has been developed. By using additional external force with some actuators, the robot automatically modifies user's motion in perception-assist when the robot detects a possibility of accidents such as collision between user and obstacles...
In order to assist the daily life motion of physically weak persons such as elderly persons, many kinds of power-assist robot have been developed. In the case of physically weak persons, perception ability to perceive the surrounding environment is often deteriorated also. A method of perception-assist has been proposed to assist not only the user's motion but also interaction of the user with his/her...
