Publication number: 20240100682Abstract: A flexible interface (130) may operably couple a head portion (110, 210) and a shaft (120, 220) of a hand tool (100, 200). The flexible interface may include a retention assembly (160) and a locking assembly (150) including an actuator (152, 250, 250?) defining a locked state and an unlocked state for the hand tool. In the unlocked state, an angle of the head portion may be pivotable relative to a pivot axis (225) substantially perpendicular to a direction of extension of the shaft and, in the locked state, the angle of the head portion is fixed. The actuator may be configured to move in a direction substantially perpendicular to the pivot axis to operate the locking assembly to transition between the locked state and the unlocked state, and configured to move in a direction substantially parallel to the pivot axis to operate the retention assembly to retain hand tool in the unlocked state. A hand tool comprising said flexible interface is also related.Type: ApplicationFiled: January 28, 2021Publication date: March 28, 2024Inventors: Minglin Shi, Cheng Yang, Yi-Hsiang Tseng, Tsung-Hsien Shen

Patent number: 10063490Abstract: Disclosed herein are systems, methods, and software for implementing runtime experiments with user interface configurations. In at least one implementation, an online application service receives access requests associated with various client applications attempting to access the online application service. In response to the access requests, the online application service communicates with an experiment control service to identify an experimental configuration in accordance with which to present a user interface to the online application service. The experiment control service selects the experimental configuration from various experimental configurations. The user interface is then presented in accordance with the experimental configuration identified for each of the client applications.Type: GrantFiled: March 14, 2014Date of Patent: August 28, 2018Assignee: Microsoft Technology Licensing, LLCInventors: Fang Wang, Albert Chik Shi Shen

Patent number: 9951190Abstract: A method for producing a wear resistant polyethylene medical implant includes forming a medical implant, such as an orthopedic implant, made at least partially of ultra high molecular weight polyethylene (UHMWPE). The polyethylene may be irradiated with gamma ray or e-beam radiation to form free radicals and then crosslinked to eliminate free radicals prior to exposure to oxygen. The so treated bearing surface of the crosslinked polyethylene is then coated with a photoinitiator. Thereafter the bearing material is photocrosslinked with ultra-violet (UV) radiation. The photocrosslinking process can also be applied to non-crosslink UHMWPE.Type: GrantFiled: July 22, 2015Date of Patent: April 24, 2018Assignee: Howmedica Osteonics Corp.Inventors: Shulin He, Zongtao Zhang, Keenan Michael Hanson, Shi-Shen Yau

Patent number: 9650476Abstract: A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part.Type: GrantFiled: October 6, 2015Date of Patent: May 16, 2017Assignee: Howmedica Osteonics Corp.Inventors: Aiguo Wang, John H.

Publication number: 20140244525Abstract: Entitlement cards having an offer term and number of user licenses for a subscription to an online service can be applied to existing subscriber accounts to add or otherwise adjust the number of user licenses associated with the subscription. When an entitlement card is added to an account, the system automatically adjusts the amount of time for each user license so that an entire value of an entitlement subscription is used and a same expiry date is maintained even when adding new user licenses to an existing account. A user interface is provided that enables a customer to change the number of user licenses for a subscription when redeeming an entitlement card to their account and view a new end date for the subscription as a whole resulting from a change in user licenses during a current subscription.Type: ApplicationFiled: February 26, 2013Publication date: August 28, 2014Applicant: MICROSOFT CORPORATIONInventors: Jignesh Kacharia, Ron E.

Patent number: 8439975Abstract: A method for manufacturing of ultrahigh molecular weight polyethylene (UHMWPE) for implants, where the implants have been machined out of UHMWPE blocks or extruded rods, has anthocyanin dispersely imbedded in the polyethylene. The implant is then exposed to ? ray or electron beam irradiation in an amount of at least 2.5 Mrad followed by a heat treatment to prevent the implant from becoming brittle in the long term as well as to improve strength and wear. The method includes mixing a powder or granulate resin of UHMWPE with an aqueous liquid that contains anthocyanin in a predetermined amount. The water is then evaporated to deposit the anthocyanin in a predetermined concentration on the polyethylene particles. The doped UHMWPE particles are compressed into blocks at temperatures in a range of approximately 135° C.-250° C. and pressures in a range of approximately 2-70 MPa. Medical implants are made from the blocks.Type: GrantFiled: September 20, 2012Date of Patent: May 14, 2013Assignee: Howmedica Osteonics Corp.Inventors: Shulin He, Shi-Shen Yau, Aiguo Wang, Daniel E.
