  • Patent number: 11765523
    Abstract: A hearing system to activate an auditory system using cerebrospinal fluids includes at least one processor configured to receive an audio signal captured using a sound sensor (e.g., a microphone), extract temporal and spectral features from the audio signal, and create modulated ultrasound signals in a range of 20 Hz to 20 kHz with ultrasound carrier frequencies in the range of 50 kHz to 4 MHz, which are ultrasound frequencies that are well-suited to reach the cerebrospinal fluids (e.g., can pass across the skull/bones to reach the cerebrospinal fluids). The system further includes at least one ultrasonic transducer which receives the modulated signal and delivers the modulated signal to the body and activates the auditory system via vibration of cerebrospinal fluids that vibrate cochlear fluids, bypassing the normal conductive pathway that uses middle ear bones and minimizing bone conduction and distortion through the skull.

  • Patent number: 11748583
    Abstract: The techniques and systems described herein relate to manufacturing, characterizing, and/or identifying one or more types of magnetic nanowires (MNWs). One or more types of MNWs may be associated with different objects, and a system may identify the objects based on the magnetic nanowires associated with the objects. For example, such techniques may involve characterizing the types of MNWs based on magnetic field transmission characteristics and ferromagnetic resonance characteristics of each type of MNW. In some examples, the techniques described herein may enable the identification of each of a plurality of types of MNWs present in a sample or object based on a combined transmission value of the sample. Such techniques may enable the development and use of barcode-like systems of different types of MNWs for labeling and identifying objects of interest.

  • Patent number: 11750366
    Abstract: A method includes receiving a first polynomial and a second polynomial, both of order n?1 and forming d polynomial segments from both the first polynomial and the second polynomial such that each polynomial segment is of order (n/d)?1. The polynomial segments of the first polynomial and the d polynomial segments of the second polynomial are used to form segment products. Each segment product is divided into a first polynomial substructure of order n/d and a second polynomial substructure of order (n/d)?1. A first polynomial substructure containing the first n/d coefficients of a product of the first polynomial and the second polynomial is summed with a second polynomial substructure to form a sum substructure. The sum substructure is used multiple times to determine coefficients of a polynomial representing the modulo xn+1 of the product of the first polynomial and the second polynomial.

  • Patent number: 11718858
    Abstract: This disclosure describes, in one aspect, a cell that includes a biocontainment system. Generally, the biocontainment system includes a coding region whose overexpression decreases growth of the cell, a transcription regulatory region that includes a silent mutation and is operably linked upstream of the coding region, and a polynucleotide that encodes a programmable transcription activator engineered to bind to the transcription regulatory region in the absence of the silent mutation. Thus, in the absence of the silent mutation, the programmable transcription activator induces overexpression of the coding region; in the presence of the silent mutation, the programmable transcription activator does not initiate overexpression of the coding region.
