  • Patent number: 12272057
    Abstract: We present a system and method for analysis of image and data of ultrasound and ultrasound with contrast medium of human pancreatic tissues to automatically diagnose acute pancreatitis of the pancreas and identify pancreatic non-viable tissues at an early stage. The system consists of a diagnostic ultrasound system with specialized software for contrast studies (ultrasound) for in vivo ultrasound examinations of human internal organs, recording reflected ultrasound signals from pancreatic tissues (without contrast material and when contrast material is injected) and an image and data processing algorithm with artificial intelligence (neural network) elements providing a diagnostic estimate of a recommendatory nature.

  • Patent number: 12134280
    Abstract: An optical device with ordered scatterer arrays for secure identity and a method of producing the same This invention discloses a method for configurable spatial control and modification of optically active resonantly coupled scatterer arrays to produce identifiable security features and a corresponding photonic secure identity device. The invention comprises at least the steps of (i) producing a deposition template from said master stamp, (ii) synthesis of a plasmonic particle colloid, (iii) producing an optically active, two-dimensional security tag template using self-assembly of said particles on said deposition template, (iv) producing a customized secure identity device from said security tag template by selective removal or modification of optical properties using ultrashort laser pulses. The produced customized plasmonic-photonic device can then be used as secure identity and anti-counterfeiting means.

  • Patent number: 11846888
    Abstract: Disclosed herein is a method that combines two different hologram origination processes in a single photoresist layer by using an interlayer to transfer structures exposed by electron beam lithography into overlapped with dot-matrix hologram areas, and fabricated holographic structures are replicated in multilayer polymer films. Dot-matrix technique is low cost process, which has high origination speed and can be used for the patterning of large areas of holograms with high diffraction efficiency. Electron beam lithography allows the formation of high resolution structures. The method allows combining these two technologies so that the final security device could contain electron beam patterned high resolution diffraction gratings, computer generated holograms, as well as dot-matrix laser patterned large hologram areas with high diffraction efficiency, providing an increased level of protection.

  • Patent number: 11842650
    Abstract: The following teachings are of a portable autonomous device and method operating independently of aircraft flight control equipment. The device can be easily moved from one aircraft to another. The device measures the acceleration of the aircraft from the instantaneous speed and the runway distance covered from the start of the acceleration. Once the runway length and take-off speed is input, the device calculates the remaining distance to safely reach the take-off speed. If the remaining runway distance is not enough for the safe take-off, the device provides visual or audible information about the situation and signals to the pilot. In other embodiments, the determination and presentation of the remaining runway length may be implemented in the aircraft flight control equipment.

  • Patent number: 9662028
    Abstract: A method and system of predicting a hypotensive episode in a patient using one or more time varying hypotension specific biomarkers corresponding to physiological processes in the patient. Data derived from sensors or other measurement devices such as ECG sensors can be used to generate biomarkers. The biomarkers can then be used to generate an acute hypotension prediction classifier, or monitored factor, derived from a three dimensional temporal representation of two or more biomarkers. When the monitored factor exceeds a predetermined threshold the method and system trigger an alarm before an appearance of a hypotensive episode in the patient.
