    Abstract: Techniques described herein relate to systems and methods for parallel DNA molecules sequencing. A preprocessor can receive raw data frames from a sensor chip including 100,000 or more cells, where each raw data frame can include detection signals from the 100,000 or more cells at a given time during the formation of the 100,000 or more cells or during the DNA molecules sequencing using the 100,000 or more cells. The preprocessor can then extract relevant information for determining states of the cells from the raw data frames, generate one or more digested frames that includes the extracted information, and send the digested frames to a processor for processing, such as base determination. Because the number of digested frames sent to the processor is less than a number of the raw data frames and the digested frames include preprocessed data, the amount of data being transferred to the processor and the amount of data processing by the processor can be reduced.

  • Patent number: 11102199
    Abstract: User identities, password, etc. represent the barrier between a user's confidential data and any other third party seeking to access this data. As multiple software applications, web applications, web services, etc. embody this confidential data it is a tradeoff between easy recollection of said identities, passwords, etc. and data security. However, malware by intercepting user credentials provides third parties access to even complex passwords, user credentials, security keys etc. even where these are changed/updated regularly. Within the prior art substantial work has gone into addressing malware. However, in many instances the user is at or very near the computer with a software application executing a transaction requiring credentials/authorization with a portable electronic device or another device. Accordingly, it would be beneficial to provide users with an out-of-band communications channel for exchanging credentials and/or keys etc.

  • Patent number: 11043058
    Abstract: An optically detectable marker having a matrix material, which is doped with individual luminescent dopants, including a first luminescent dopant and a second luminescent dopant. The first luminescent dopant includes a first unique absorption band such that the first dopant may be excited by illumination of a first wavelength. The first dopant is distributed in the matrix material so as to form a first spatial pattern in the matrix material, which pattern may be optically detected by illuminating the marker by a light source illuminating light of the first wavelength. The second luminescent dopant includes a second unique absorption band such that the second dopant may be excited by illumination of a second wavelength, different from the first. The second dopant is distributed in the matrix material so as to form a second spatial pattern in the matrix material, which pattern may be optically detected by illuminating the marker by a light source illuminating light of the second wavelength.

  • Patent number: 10949642
    Abstract: A fingerprint image capture system comprises an electro-optical material which captures a static fingerprint image and an apparatus for converting the static fingerprint image into an electronic signal. The image capture system includes an electrode for contacting a finger, and a bias supply for creating an electric field where epidermal ridges contact the electro-optical material. A transistor array senses charge or optical density variations in the electro-optical material to create an electronic representation of the fingerprint image. An initialization electrode places the electro-optical material into a uniform condition prior to acquisition of the fingerprint image. A physical artifact of the fingerprint image can be archived by removing the electro-optical material from the system following the fingerprint image acquisition.
