Patent number: 11755447Abstract: Systems and methods for predictive performance indicators for storage devices are described. The data storage device may process host storage operations and maintenance operations that impact real-time performance. A performance value and corresponding threshold may be determined. Increases in maintenance operations and resulting changes in the performance value may be predicted. When the predicted change in performance value crosses the performance threshold, the host device may be notified.Type: GrantFiled: September 9, 2022Date of Patent: September 12, 2023Assignee: Western Digital Technologies, Inc.Inventors: Michael Lavrentiev, Narendhiran Chinnaanangur Ravimohan, Meenakshi C

Patent number: 10881027Abstract: A socket includes a housing configured to receive a removable Data Storage Device (DSD) and a Thermal Interface Material (TIM). An assembly of the socket is attached to the housing and configured to expand due to heat. In a thermally expanded state, the assembly causes the TIM to come into contact with the removable DSD to draw heat away from the removable DSD. According to another aspect, a retaining strip or assembly is attached to a housing in a configuration such that the retaining strip or assembly expands due to heat to increase a resistance to removal of the removable DSD from the housing when the retaining strip or assembly is in a thermally expanded state.Type: GrantFiled: June 24, 2019Date of Patent: December 29, 2020Assignee: Western Digital Technologies, Inc.Inventors: John Burke, Michael Lavrentiev

Publication number: 20190146930Abstract: A system and method are disclosed for an event lock storage device. The storage device includes a user partition and an event partition (which may be associated with an event). The storage device receives data from a host device, and stores the data in the user partition. In response to receiving an indication of an event, the storage device may designate the data as part of the event partition. The event partition may include a set of access rules that is different from the user partition, such as more restrictive rules for modification or deletion of a file containing the data.Type: ApplicationFiled: January 16, 2019Publication date: May 16, 2019Inventors: Filip Verhaeghe, Bsa Chung, Samuel Yu, Michael Lavrentiev

Patent number: 8233075Abstract: Methods and systems for adjusting a video imaging system that includes an auto-focus mechanism wherein an input from a user of the video imaging system invokes an auto-focus procedure. Responsive to the input, the auto-focus mechanism is scanned over a range of focal distance from a first setting to a second setting indicated by the input. A sequence of images using the video imaging system is captured while scanning the auto-focus mechanism over the range. The images in the sequence are processed so as to compute a measure of focal quality with respect to each of the images. The measure of the focal quality is analyzed so as to select an optimal focal distance, and the auto-focus mechanism is set to the selected focal distance.Type: GrantFiled: May 22, 2008Date of Patent: July 31, 2012Assignee: Gyrus ACMI, Inc.Inventors: Michael Lavrentiev, Stuart Wolf, Doron Adler, Albert M.

Publication number: 20090046171Abstract: A method for imaging includes defining a set of one or more color correction parameters having values that vary over a predefined color space. For each of the pixels in an input image, the location of the respective input color is determined in the color space, and a value of the one or more color correction parameters is selected responsively to the location. The respective input color is modified using the selected value so as to produce a corrected output color of the pixel in an output image.Type: ApplicationFiled: August 16, 2007Publication date: February 19, 2009Applicant: C2Cure, Inc.Inventors: Simon Kogan, Doron Adler, Stuart Wolf, Michael Lavrentiev
