Patent number: 11992392Abstract: Disclosed herein are embodiments of a wound treatment apparatus with electronic components integrated within a wound dressing. In some embodiments, a wound dressing apparatus can comprise a wound contact layer, an absorbent layer over the wound contact layer, the absorbent layer comprising one or more apertures, a cover layer configured to cover and form a seal over the wound contact layer and the absorbent layer, and an electronics assembly comprising a negative pressure source. A portion of the cover layer overlying the one or more apertures in the absorbent layer can be configured to be compressed within the aperture in the absorbent layer when negative pressure is applied to the wound dressing apparatus. The compressed cover layer can indicate a level of negative pressure below the cover layer. In some embodiments, the wound dressing apparatus can comprise an indicator material layer and a cover layer configured to cover and form a seal over the wound contact layer and the indicator material layer.Type: GrantFiled: November 10, 2022Date of Patent: May 28, 2024Assignee: Smith & Nephew PLCInventors: Michael Earl, Frederick Jethro Harrison, William Kelbie, Reece Knight, David Peter Lloyd, Joseph William Robinson, Daniel Lee Steward, Grant West

Patent number: 11972425Abstract: Methods, apparatuses, and computer program products are disclosed for account verification. An example method includes receiving a request for payment transmission from a payment provider device and generating a first verification element for a payment destination device associated with the request for payment transmission. The method further includes transmitting the first verification element to the payment destination device via a first real-time payment message. In an instance in which the computing device receives responsive authorization from the payment destination device, the method includes verifying the payment destination device. In response to verifying the payment destination device, the method includes transmitting a first real-time payment to the payment destination device. In an instance in which the computing device fails to receive responsive authorization from the payment destination device, the method includes transmitting a verification failure notification to the payment provider device.Type: GrantFiled: August 30, 2019Date of Patent: April 30, 2024Assignee: Wells Fargo Bank, N.A.Inventors: Daniel Alexander David, Christina Zikeli, Kellie L.

Publication number: 20220320832Abstract: The present disclosure is directed to light-distribution systems on photonic integrated circuits (PIC) that split and amplify a light signal received from at least one remotely located laser into a plurality of amplified light signals, where amplification is provided by an integrated semiconductor optical amplifier (SOA). By locating the laser remotely with respect to the SOA-based PIC, the laser and PIC can be subjected to different ambient environmental conditions. Additionally, a lower-power laser can be used since the optical loss associated with splitting is compensated for by the amplification. As a result, lower current densities and optical powers can be used in both the source laser and the SOA. In some embodiments, the sequence of power splitting and amplification is repeated multiple times, thereby enabling system to scale gracefully.Type: ApplicationFiled: March 30, 2022Publication date: October 6, 2022Inventors: Brian KOCH, Alan LIU, Daniel Knight SPARACIN

Patent number: 10151939Abstract: Embodiments of the invention describe systems, apparatuses and methods for providing athermicity and a tunable spectral response for optical filters. Finite impulse response (FIR) filters are commonly implemented in photonic integrated circuits (PICs) to make devices such as wavelength division multiplexing (WDM) devices, asymmetric Mach-Zehnder interferometers (AMZIs) and array waveguide gratings (AWGs). Athermicity of an FIR filter describes maintaining a consistent frequency transmission spectrum as the ambient temperature changes. A tunable spectral response for an FIR filter describes changing the spectrum of an FIR filter based on its application, as well as potentially correcting for fabrication deviations from the design. In addition, embodiments of the invention reduce energy dissipation requirements and control complexity compared to prior art solutions.Type: GrantFiled: March 15, 2018Date of Patent: December 11, 2018Assignee: Aurrion, Inc.Inventors: Jonathan Edgar Roth, Daniel Knight Sparacin, Gregory Alan Fish
