Patent number: 11633871Abstract: A system for cutting medical tubing sourced from a spool of tubing uses two actuator groups that each reciprocate along a respective track, which are parallel to each other. Each actuator group has a clamp and a cutting tool which have an operative position along a common axis. The tubing is fed along the common axis to be operated on by the actuator groups. A forward actuator group clamps onto the tubing and is then moved along its track, pulling the tubing. A rearward actuator group then clamps onto the tubing and cuts the tubing. While still clamped onto the tubing, the rearward actuator group is moved forward, pulling more tubing, and the actuator group that was forward is moved to the rearward position and the process is repeated iteratively to produce tubing sections cut to the desired length. The tubing is pressurized and kept under pressure to straighten the tubing.Type: GrantFiled: June 3, 2021Date of Patent: April 25, 2023Assignee: Engineering Resources Group, Inc.Inventor: Christopher Ross

Patent number: 11524417Abstract: A system and a method for adaptively releasing a lubricant or a cosmetic for a razor cartridge, a sensing unit detects a property of at least one of skin, air, water and a chemical agent in a region adjacent to the razor cartridge. A smart polymer provided on the razor cartridge is selectively responsive to a characteristic external stimulus by undergoing a physical or chemical change. A processing unit controls the release of the lubricant or the cosmetic by providing the characteristic external stimulus to cause the smart polymer to undergo a change. The processing unit compares the detected property to a reference threshold parameter and determines whether to provide the characteristic external stimulus to the smart polymer based on the comparison, thereby generating the lubricant or the cosmetic. The determined level of depletion of the smart polymer is indicated by a light, aural, or haptic indication.Type: GrantFiled: June 30, 2021Date of Patent: December 13, 2022Assignee: BIC Violex Single Member S.A.Inventors: Vasiliki Panagiotopoulou, Athanasia Panou, Panagiotis Moustakas, Georgios Pyrris

Patent number: 11499318Abstract: A roof cutter and a method of cutting a roof is provided. The roof cutter includes a base that is movable between a retracted configuration and a cutting configuration. In the retracted configuration, the blade is displaced from the roof. In the cutting configuration, the blade is positioned so as to facilitate cutting of the roof. The roof cutter includes a stop assembly and an engagement member that is configured to engage with the stop assembly when the base is in the cutting configuration, thereby establishing a maximum cutting depth.
