Publication number: 20230409944Abstract: An interface between cryogenic computational hardware and room temperature computational hardware includes a plurality of discrete stages, including a first stage at room temperature and a last stage at a cryogenic temperature. Each successive stage is configured for operation at a corresponding refrigeration temperature that is lower than the refrigeration temperature of each preceding stage and includes a set of planar transmission lines. The transmission lines of any given stage other than the first stage are proximally coupled to and contiguous with the transmission lines of an immediately preceding stage. The transmission lines of the first stage are proximally coupled to the room temperature computational hardware, and the transmission lines of the last stage are proximally coupled to the cryogenic computational hardware. Each stage has shielding configured to block electromagnetic radiation external to such stage.Type: ApplicationFiled: October 14, 2022Publication date: December 21, 2023Inventors: Samuel H.

Patent number: 11465175Abstract: A haptic actuator includes mechanical links defining a first J-trajectory and mechanical links defining a second J-trajectory as well as a motor coupled to the mechanical links so as to synchronously accelerate a first mass over the first J-trajectory and a second mass over the second J-trajectory. During a first time interval, reactive forces of the first mass accelerating substantially balance reactive forces of the second mass accelerating and during a second time interval reactive forces of the first mass accelerating do not substantially balance reactive forces of the second mass accelerating. This un-balanced condition results in a tap signal being produced.Type: GrantFiled: October 19, 2020Date of Patent: October 11, 2022Assignee: Vibrant Composites Inc.Inventors: Pratheev Sabaratnam Sreetharan, Andrew Baisch, Michael Karpelson

Publication number: 20210202092Abstract: A system, an image analyzer and a method for diagnosing a presence of a disease or a condition in an image of a subject, for example, a veterinary patient, are provided including: classifying the image to a body region, and obtaining a classified, labeled, cropped, and oriented sub-image; directing the sub-image to artificial intelligence processor for obtaining an evaluation result, and comparing the evaluation result to a database library of evaluation results and matched written templates or a dataset cluster to obtain at least one cluster result; measuring the distance between the cluster result and the evaluation result to obtain at least one cluster diagnosis; and assembling the cluster diagnosis and the matched written templates to obtain a report to display the report to a radiologist. These system, analyzer and method are achieved in greatly reduced lengths of time and are useful for cost and time savings.Type: ApplicationFiled: December 28, 2020Publication date: July 1, 2021Applicant: Vetology Innovations, LLCInventors: Seth Wallack, Ruben Venegas, Ariel Ayaviri Omonte, Pratheev Sabaratnam Sreetharan, Yuan-Ching Spencer Teng

Patent number: 9833978Abstract: A multi-layer, super-planar structure can be formed from distinctly patterned layers. The layers in the structure can include at least one rigid layer and at least one flexible layer; the rigid layer includes a plurality of rigid segments, and the flexible layer can extend between the rigid segments to serve as a joint. The layers are then stacked and bonded at selected locations to form a laminate structure with inter-layer bonds, and the laminate structure is flexed at the flexible layer between rigid segments to produce an expanded three-dimensional structure, wherein the layers are joined at the selected bonding locations and separated at other locations.Type: GrantFiled: July 15, 2014Date of Patent: December 5, 2017Assignee: President and Fellows of Harvard CollegeInventors: Pratheev Sabaratnam Sreetharan, John Peter Whitney, Robert J.
