  • Patent number: 11560793
    Abstract: Systems and methods are provided for analyzing isotopes of a gas from a wellbore to determine geological information associated with the wellbore. A drill device can be used to drill rocks or particles in a wellbore, which can cause a gas to be released within the wellbore. Fluid can be pumped into the wellbore as the drill bit drills the rocks or particles and the fluid, along with the gas released, can flow through the wellbore and to a surface of the wellbore. A gas detector can be positioned near the wellbore for detecting an amount of gas and a type of gas in the fluid and gas mixture and transmitting data about the amount and type of the gas to a computing device. The computing device can output data based on the amount and type of gas in the mixture for determining geological information about the wellbore.

  • Patent number: 11525776
    Abstract: A droplet sensor includes an optical cover that forms part of a spheroid, a major axis of the spheroid being a vertical axis, a light emitting/receiving device disposed at a position offset from a first focal point of the spheroid along the major axis, and a reflector disposed in vicinity of a second focal point of the spheroid. The optical cover has an effective detection area between the light emitting/receiving device and the reflector. The effective detection area satisfies a total internal reflection condition at an interface with a gas, and does not satisfy the total internal reflection condition at an interface with a liquid. The reflector reflects, towards a light receiving surface of the light emitting/receiving device, light totally reflected by the effective detection area, or reflects, towards the effective detection area, light directly incident on the reflector from the light emitting/receiving device.

  • Patent number: 11204384
    Abstract: In some embodiments, a system and/or method may test logic blocks for an integrated circuit. To alleviate problems associated with current methods of integrated circuit testing, a system may include a power switch control signal on a different voltage rail. In some embodiments, a Test VDD may be used to isolate the power switches from the rest of the logic cells in an integrated circuit. During testing, each logic block may be powered individually using the Test VDD to control the power switches to the logic blocks. When a logic block short is identified, the nonviable logic block may be isolated to such that the nonviable logic block is not used during the future and only viable logic blocks are used in the integrated circuit. This allows for use of logic within an integrated circuit that might otherwise have been discarded or destroyed because of one or more shorts.
