Publication number: 20200078026Abstract: Retro guidewire reamers include a drill having a tubular shaft configured to be disposed over a guidewire and at least one cutting member movably disposed adjacent the distal end of the shaft. A slide actuator is moveably coupled to the shaft and to an actuator wire slidable along the shaft. The actuator wire is operative to move the at least one cutting member between a closed position and a deployed position when the slide actuator is moved along the shaft. The retro guidewire reamers include mechanisms to protect the mechanical joint between the actuator wire and the slide actuator which prevent the actuator wire from disengaging from the slide actuator when the cutting member is obstructed by a guidewire.Type: ApplicationFiled: September 7, 2018Publication date: March 12, 2020Applicant: Smith & Nephew, Inc.Inventors: Geoffrey Karasic, Miles Steven Holt Malone, Roman Gutierrez, David Callaghan, Matthew Cunningham, Chun Liu

Patent number: 10204235Abstract: Applications are stored on removable storage of a mobile device in an encrypted form to provide isolation and piracy protection. In one implementation, each application is encrypted using its own associated encryption key that is generated based on an identifier of the application and a master key that is associated with a trusted platform module of the mobile device. In another implementation, each application is encrypted using two associated encryption keys. One key is used to encrypt binary data associated with the application such as source code, and the other key is used to encrypt application data such as graphics and configuration files. The encryption keys are each generated using the identifier of the application, the master key, and identifiers of the folders where the corresponding data types are stored on the mobile device. The removable storage includes SD cards formatted using the FAT or exFAT file systems.Type: GrantFiled: June 28, 2016Date of Patent: February 12, 2019Assignee: Microsoft Technology Licensing, LLCInventors: David Callaghan, Ravisankar Pudipeddi, Geir Olsen, Sachin Patel, JianMing Zhou, Dylan D'Silva

Patent number: 9544374Abstract: An operating system or other software resident on an electronic processing device employs aggregated timestamps. In this way timestamps can be generated and compared to one another without the need for a real-time clock with a power backup. Aggregated time includes the last known time that the device synchronized its clock with a reference time available over a network. Aggregated time also includes a relative time value which in part accumulates using a session clock whenever the device is powered-up. When network time becomes available the operating system or other software will use this information to fix up the already generated aggregated timestamps. A comparison of timestamps will most of the time be resolved for stamps generated on the same device and will generally be resolved by comparing time frames when the timestamps being compared are generated by different devices.Type: GrantFiled: January 30, 2015Date of Patent: January 10, 2017Assignee: Microsoft Technology Licensing, LLCInventors: David Callaghan, Sergey Karamov
