Patent number: 10610093Abstract: Embodiments of the invention are related to a method and a system for eyesight diagnosis. The system includes a vision test unit and a controller. The vision test unit includes at least one eye movement tracking unit configured to track the movement of a portion of the eye, at least one screen for visual stimulation and a shuttering unit configured to controllably block the field of view (FOV) of each eye separately. In some embodiments, the controller includes a processor and a non-volatile memory that store thereon instructions that when executed by the processor causes the controller to: display to a patient a first visual stimulation on the at least one screen, cause the shuttering unit to block the FOV of a first eye of the patient while unblocking the FOV of a second eye, receive a first signal indicative of the second eye movement of the patient from the at least one eye movement tracking unit and diagnose the patient's eyesight based on the received first signal.Type: GrantFiled: December 14, 2017Date of Patent: April 7, 2020Assignee: GREEN C.TECH LTD.Inventor: Michal Green

Patent number: 6635213Abstract: The subject of the invention is a method of manufacturing centrifuged, glass fiber-reinforced synthetic material pipes wherein liquid, curable resin, which contains a filler, together with glass fibers, additives for the curing process, possibly also with sand, is introduced into a rotating mould and the temperature of the mould is between 40° C. and 75° C. as the raw materials are introduced. The resin used in the layers in the outer region of the pipe has a gel time which is equal to or greater than the gel time of the resin used for the inner region of the pipe and the resin comprising a filler content of at least 40% is used. Furthermore, once the exothermal reaction has commenced, warm water is sprayed onto the mould in order to maintain the temperature of the mould at least at 60° C. until the pipe is removed.Type: GrantFiled: July 18, 2001Date of Patent: October 21, 2003Assignee: C-Tech Ltd.Inventor: Börge Carlström

Patent number: 6450547Abstract: A pipe coupling according to the invention comprises a socket (2) of glass-fiber reinforced plastics material and a membrane (4) of elastic material which is formed at at least one end as a seal and comprises a sleeve section (8). Where the membrane is formed as a seal, it has at the end where the pipe (20) is to be introduced (thus at the outer end), a short cylindrical band (14). In the cylindrical band the membrane has a constant wall thickness, which is backed by the glass-fiber reinforced socket material of the pipe coupling.Type: GrantFiled: July 18, 2001Date of Patent: September 17, 2002Assignee: C-tech LtdInventor: Börge Carlström
