Abstract: In specific embodiments, provided is a material for preventing adhesion of membranes in an ophthalmic surgery for treatment of glaucoma or the like without using mitomycin-C or the like. Particularly provided is such material, which is easy to handle and has no risk of histolysis or infections. In a production method of a preferred embodiment, prepared are: aldehyde-modified dextran (first reactant) having weight-average molecular weight of 10,000-5,000,000 and introduced aldehyde group-per-anhydrous glucose unit (mol/AGU) of 0.4-0.7; and succinic anhydride-added poly-L-lysine (second reactant) having weight-average molecular weight of 1000-100,000 and having residual amino group ratio of 80-99%; then, they are mixed together so that aldehyde group-to-amino group molar ratio becomes 0.9-1.1 and are reacted in presence of water so that polymer concentration becomes 8-20%; and a hydrogel produced by the reaction, or a suspension before gelation, is freeze-dried to produce a porous sheet having a thickness of 0.

Abstract: A self-cleaning robotic kitchen system has a robotic arm, a camera or sensor, a cleaning tool and computer and electronics. The computer is programmed and operable to (a) determine whether to commence a first cleaning phase for cleaning a first section based on the at least one sensor or camera; (b) control pick up of the cleaning tool; (c) control the robotic arm to clean according to a predefined route or pattern to scrub the first section; (d) query whether the first section is clean; and (e) dock the cleaning tool if the first section is clean. Related methods are also described.

Abstract: An automated food preparation system includes an enclosure defining a robotic workspace, a robotic arm and a plurality of functional stations for dispensing raw food to a bin, transferring the raw food from the bin to a fry basket, frying the raw food, and transferring the cooked food to a receiving pan. The system is programmed and operable to monitor its health, and to adjust operating parameters in order to compensate for detected conditions outside of a predetermined acceptable range. Related methods are described.

Abstract: An automated food frying system includes an enclosure defining a robotic workspace, a robotic arm and a plurality of functional stations for dispensing raw food to a bin, transferring the raw food from the bin to a fry basket, frying the raw food, and transferring the cooked food to a receiving pan. Optionally, an auto-drawer station is arranged and operable within the enclosure to transfer an entire fry basket of order-specific food between an operator and the robotic arm without the operator or the robotic arm penetrating the enclosure. Related methods are described.

Abstract: A travel control system of an automated guided vehicle including, an actual guided-vehicle travel controller including an actual control program causing a plurality of actual guided vehicles to travel along a plurality of travel routes crossing one another in an actual conveyance area, a virtual guided-vehicle travel controller including a virtual control program causing a plurality of virtual guided-vehicles to travel by imitating a shape and a motion of the actual guided vehicles in a virtual conveyance area, a virtual guided-vehicle travel monitoring processor which, in a case of occurrence of a collision or stop abnormality by the virtual guided vehicles, detects and records the abnormal phenomenon, a monitoring-result output transmitter which outputs the detected abnormal phenomenon to outside, and an update-data input receiver which receives update data modified by referring to the output abnormal phenomenon from outside and finally reflects it in the actual control program.

Abstract: A powder spray device includes a funnel member, a first three-way joint, an air-current supply tube, a discharge tube, a vibration motor, a bypass air-current tube, and a switching mechanism. The first three-way joint has a first opening connected to an outlet at a lower end of the funnel member. The air-current supply tube and discharge tube are respectively connected to second and third openings of the first three-way joint. The vibration motor is fixed onto an outer surface of a funnel body of the funnel member. The bypass air-current tube branches off from the air-current supply tube and is connected to the discharge tube. The switching mechanism switches from and to standby state, in which compressed gas is sent only through the bypass air-current tube, to and from spray-coating state, in which compressed gas is sent out through the air-current supply tube, and also through the bypass air-current tube.

Abstract: A sheet-shaped tissue adhesive/reinforcement includes a base sheet having biodegradability and a communicative porous structure, and an adhesive resin layer fixed and formed on the base sheet. The adhesive resin layer includes a first reactant made of an aldehyded glycan and a second reactant made of partially carboxylated polylysine, and has a molar ratio of 1 as a ratio of an aldehyde group of the first reactant to an amine group of the second reactant. The adhesive resin layer has a structure of granules derived from powder of the first reactant, and a connecting layer derived from the second reactant. The connecting layer connects the granules to each other and fixes each of the granules onto the base sheet, throughout the sheet-shaped tissue adhesive/reinforcement.
