  • Patent number: 12154779
    Abstract: The invention generally relates to systems and methods for separating ions at about or above atmospheric pressure. In certain embodiments, the invention provides systems that include an ionization source that generates ions and an ion trap. The ion trap is maintained at about or above atmospheric pressure and includes a plurality of electrodes and at least one inlet configured to receive a gas flow and at least one outlet. The system is configured such that a combination of a gas flow and one or more electric fields produced by the electrodes separates the ions based on mass-to-charge ratio and sends the separated ions through the at least one outlet of the ion trap.

  • Patent number: 11330993
    Abstract: An optical proximity sensor assembly includes an optical proximity sensor with an IR LED emitting light having an infrared wavelength, an IR photo detector sensitive to the infrared wavelength, an optical barrier blocking direct light rays from the LED to the IR photo detector and permitting reflected light rays to reach the at least one photo detector; and an electronic integrated circuit with an amplifier for amplifying a signal detected by the photo detector, an analog to digital converter, LED drivers, noise reduction and ambient light cancellation circuitry, and a digital interface for communication with a microcontroller. The optical proximity sensor is accommodated on a wearable carrier. A single sensor may include a plurality of identical or different LEDs, a plurality of photodiodes, or both. Also, several sensors may be placed on a person's skin along a vascular path to obtain data relating to blood flow and artery stiffness.

  • Patent number: 10839948
    Abstract: Embodiments herein relate to data storage and retrieval using information-encoding polymers encapsulated in droplets stored in a microfluidic droplet storage array. In various embodiments, a data storage apparatus may include a microfluidic droplet storage array to store one or more droplets containing one or more information-encoding polymer molecules in one or more droplet storage locations, and an interface coupled with the microfluidic droplet storage array to receive the one or more droplets from a data writer that writes the one or more droplets into the microfluidic droplet storage array. Other embodiments may be described and/or claimed.
