Publication number: 20170119248Abstract: Lower sampling rates have been found to provide sufficient data for use in the method of U.S. Pat. Nos. 7,071,831, 7,616,125 and 7,791,491. The method of determining drowsiness includes the steps of receiving eye movement data collected at sampling rates as low as 20 Hz. The data is preferentially interpolated to provide a data set at a higher sampling rate in the order of 500 Hz. For each data point, values of amplitude and velocity of eye movement and whether the measures relate to eyelid opening or closing are derived. An algorithm is then used to obtain values of the amplitude to velocity ratios of eyelid opening and closing and using these values in an algorithm for providing a measure of drowsiness. With this method eyelid and eye movement may be monitored using any suitable technology or sensor including video or digital camera technology to identify and measure the appropriate ocular movements.Type: ApplicationFiled: June 19, 2015Publication date: May 4, 2017Applicant: SDIP HOLDINGS PTY LTDInventors: Trefor MORGAN, Scott COLES, Andrew TUCKER

Patent number: 8954665Abstract: Systems and methods for tracking changes and performing backups to a storage device are provided. For virtual disks of a virtual machine, changes are tracked from outside the virtual machine in the kernel of a virtualization layer. The changes can be tracked in a lightweight fashion with a bitmap, with a finer granularity stored and tracked at intermittent intervals in persistent storage. Multiple backup applications can be allowed to accurately and efficiently backup a storage device. Each backup application can determine which block of the storage device has been updated since the last backup of a respective application. This change log is efficiently stored as a counter value for each block, where the counter is incremented when a backup is performed. The change log can be maintained with little impact on I/O by using a coarse bitmap to update the finer grained change log.Type: GrantFiled: May 14, 2013Date of Patent: February 10, 2015Assignee: VMware, Inc.Inventors: Christian Czezatke, Krishna Yadappanavar, Andrew Tucker

Patent number: 8819383Abstract: One or more techniques and/or systems are provided for non-disruptively addressing misalignment between a virtual data format and an underlying data format. Virtual data, such as a guest operating system of a virtual machine, may be stored within a virtual structure, such as a virtual machine disk, according to a virtual data format. The virtual structure may be stored within a storage device according to a storage data format. If misalignment is detected, then a new data container may be created within the storage device. A shim, sized according to a misalignment offset, may be inserted into the new data container in order to align the new data container with the storage device. Virtual data may be migrated from the virtual structure to the new data container to achieve alignment. During the migration, the virtual data may remain available from the virtual structure (e.g., a virtual machine may still execute).Type: GrantFiled: February 17, 2012Date of Patent: August 26, 2014Assignee: NetApp, Inc.Inventors: Varun Jobanputra, Andrew Tucker, Eric Paul Forgette, Subramaniam V.
