Patent number: 11602745Abstract: A pipette module 10 has a pipette-module frame 12 attachable to the z-axis frame 120 of a liquid handling system 100. A translatory-motion frame 14 attached to the pipette-module frame 12 is movable with respect thereto by a motor 16. A pneumatic aspirator assembly 18 including a cylinder 20, tube 24, tube tip 26 and pressure sensor 28 is attached to the translatory-motion frame 14. A piston 22 disposed in the cylinder 20 is fixedly attached to the frame 12. A controller 30 for the pipette module 10 has a liquid surface detection mode which enables a pressure feedback control algorithm causing the motor 16 to move the translatory-motion frame 14 in a z-axis translator motion until a change in a pressure in the tip 26 as sensed by the pressure sensor 28 indicates that the tip 26 has made contact with the liquid surface 110.Type: GrantFiled: April 6, 2018Date of Patent: March 14, 2023Inventors: Hirofumi Tamai, Chaojun Zhou

Patent number: 10272006Abstract: A care method and a care robot that can simplify care and reduce the burden on a caregiver, in particular the burden on the caregiver during the transfer of a care receiver. A sheet is spread out on top of a bed, and the care receiver is laid on the sheet. The sheet is formed so that both ends thereof have parts to be held that are held by arms of a robot. The robot and the arms are positioned relative to the care receiver, and the robot is moved towards the bed so that the arms hold the parts to be held. The arms are raised by a predetermined distance, and when the arms are in the raised state, the robot is moved away from the bed.Type: GrantFiled: March 9, 2015Date of Patent: April 30, 2019Assignee: MUSCLE CORPORATIONInventors: Hirofumi Tamai, Satoshi Tamai
