Patent number: 10825855Abstract: Bending a flexible x-ray detector to image a curved structure or object will distort the object appearance when compared to an image captured by a flat/rigid detector. An image distortion of this type can be corrected when the shape (relative bend position) of the x-ray detector is known. Incorporating strain sensors on the flexible x-ray detector makes it possible to record the local bend of the flexible x-ray detector when an image is taken. This shape information can be used to either label or correct for the image distortions created by bending the x-ray detector to assist users more accustomed to viewing images produced by flat/rigid x-ray detectors.Type: GrantFiled: December 13, 2018Date of Patent: November 3, 2020Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Julie A. Bert, Robert A. Street, John C. Knights

Patent number: 10608041Abstract: Transitioning conventional x-ray detector materials and structures to bendable or flexible (e.g., plastic) substrates makes them rugged against breakage when dropped but exposes the detectors to damage if bent. Disclosed are bendable digital x-ray detector structures that are rugged with regard to bending as well as dropping. The structures provide strain matching between layers so that a detector backplane is in and/or near the mechanical neutral plane and therefore less susceptible to bending stress.Type: GrantFiled: April 12, 2018Date of Patent: March 31, 2020Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Robert A. Street, Julie A. Bert, John C. Knights

Patent number: 10382448Abstract: Methods and systems are described for detecting command injection attacks. A positive, taint inference method includes receiving signature fragments on one hand, converting command injection instructions into command fragments on another hand, thus identifying potential attacks upon the condition that a command injection instruction includes critical untrusted parts by using signature fragments. A system detects command injection attacks using this kind of method, and remediates and rejects potential attacks.Type: GrantFiled: April 20, 2017Date of Patent: August 13, 2019Assignee: University of Virginia Patent FoundationInventors: Anh Nguyen-Tuong, Jack W.

Patent number: 10197831Abstract: A flexible TFT backplane includes, a flexible substrate, a first set of address line contacts associated with the substrate, and a second set of address line contacts associated with the substrate. The first set of address line contacts and the second set of address line contacts are located at opposite sides of the substrate from each other, defining a vertical direction. A first set of address lines designed to run in one of the vertical direction and a diagonal or non-vertical direction with respect to the defined vertical direction, with the first set of address lines connected to the first set of address line contacts. Also provided is a second set of address lines designed to run in one of a diagonal or non-vertical direction with respect to the defined vertical direction, and a combination of diagonal and horizontal directions with respect to the vertical direction, with the second set of address lines connected to the second set of address line contacts.Type: GrantFiled: December 18, 2017Date of Patent: February 5, 2019Assignee: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: Robert A.

Publication number: 20140374912Abstract: Standard solder-based interconnect structures are utilized as mechanical fasteners to attach an IC die in a “flip-chip” orientation to a support structure (e.g., a package base substrate or printed circuit board). Electrical connections between the support structure and the IC die are achieved by curved micro-springs that are disposed in peripheral regions of the IC die and extend through a gap region separating the upper structure surface and the processed surface of the IC die. The micro-springs are fixedly attached to one of the support structure and the IC die, and have a free (tip) end that contacts an associated contact pad disposed on the other structure/IC die. Conventional solder-based connection structures (e.g., solder-bumps/balls) are disposed on “dummy” (non-functional) pads disposed in a central region of the IC die. After placing the IC die on the support structure, a standard solder reflow process is performed to complete the mechanical connection.Type: ApplicationFiled: June 24, 2013Publication date: December 25, 2014Inventor: John C.

Publication number: 20130239346Abstract: A toothbrush assembly can include a plurality of bristles and a toothbrush body. The toothbrush body can include an indicator to provide information to a user using the toothbrush during a teeth cleaning session. The indicator can operate independent of any power supply external to the toothbrush assembly. A sensing mechanism can provide an electric signal to the indicator responsive to the user using the toothbrush assembly during the teeth cleaning session. An energy scavenging mechanism can provide operating power to the indicator responsive to the user using the toothbrush assembly during the teeth cleaning session.Type: ApplicationFiled: March 14, 2012Publication date: September 19, 2013Applicant: PALO ALTO RESEARCH CENTER INCORPORATEDInventors: John C.
