Publication number: 20240169478Abstract: This disclosure provides methods, devices, and systems for image scaling. The present implementations more specifically relate to downscaling techniques that preserve a subset of pixel values in a digital image so that all reconstructed pixel values in the upscaled image can be interpolated based on two or more preserved pixel values. In some aspects, an image downscaler may partition a digital image into a number of image tiles based on a base tile size and one or more scaling factors associated with a downscaling operation used to downscale each image tile. The base tile size indicates the dimensions of the downscaled tiles. The one or more scaling factors indicate distances between the pixel values preserved as a result of one or more iterations, respectively, of the downscaling operation, where each iteration preserves a smaller subset of the pixel values from the original image (as a lower resolution tile).Type: ApplicationFiled: November 21, 2022Publication date: May 23, 2024Applicant: Synaptics IncorporatedInventors: Scott Liam RANSOM, Paul JAMES, Timothy John BORER

Publication number: 20230160884Abstract: Processes and compositions are described for preparing new, colloidally stable, coated nanomagnetic particles useful for both in-vitro and in-vivo biomedical applications, including cell targeting and capturing cells, microorganisms, and cellular organelles or entities such as exosomes. These nanomagnetic particles can also be used as imaging contrast agents due to their small size and high magnetic moment. The nanomagnetic particles include a series of sequentially added, stabilizing surface coatings rendered onto nano-sized magnetic crystal clusters (e.g., magnetite particles) to impart colloidal stability in complex biological samples with minimal leaching of the coating materials, high binding capacity, and low non-specific binding. Another benefit of this invention is the ability to utilize both external and internal magnetic field-generating separation devices to effect separation of the magnetic nanoparticles.Type: ApplicationFiled: January 19, 2023Publication date: May 25, 2023Applicant: BIOLEGEND, INC.Inventors: DHANESH GOHEL, HONG ZHANG, JOHN RANSOM

Patent number: 8093121Abstract: An electrostatic discharge (ESD) transistor structure includes a self-aligned outrigger less than 0.4 microns from a gate electrode that is 50 microns wide. The outrigger is fabricated on ordinary logic transistors of an integrated circuit without severely affecting the performance of the transistors. The outrigger is used as an implant blocking structure to form first and second drain regions on either side of a lightly doped region that underlies the outrigger. The self-aligned outrigger and the lightly doped region beneath it are used to move the location of avalanche breakdown upon an ESD event away from the channel region. Durability is extended when fewer “hot carrier” electrons accumulate in the gate oxide. A current of at least 100 milliamperes can flow into the drain and then through the ESD transistor structure for a period of more than 30 seconds without causing a catastrophic failure of the ESD transistor structure.Type: GrantFiled: September 29, 2011Date of Patent: January 10, 2012Assignee: IXYS CH GmbHInventors: John A.

Patent number: 7884489Abstract: An insulative substrate includes a plurality of flexible retaining clips and a plurality of alignment and retaining pins. A metal leadframe includes a plurality of leads. Each lead terminates in a spring contact beam portion. The leadframe is attached to the substrate (for example, by fitting a hole in each lead over a corresponding alignment and retaining pin and then thermally deforming the pin to hold the lead in place). An integrated circuit is press-fit down through the retaining clips such that pads on the face side of the integrated circuit contact and compress the spring contact beams of the leads. After the press-fit step, the retaining clips hold the integrated circuit in place. The resulting assembly is encapsulated. In a cutting and bending step, the leads are singulated and formed to have a desired shape. The resulting low-cost package involves no wire-bonding and no flip-chip bond bump forming steps.Type: GrantFiled: January 12, 2010Date of Patent: February 8, 2011Assignee: IXYS CH GmbHInventors: Thomas Stortini, John A.
