  • Patent number: 10466312
    Abstract: A method for detecting a magnetic field acting on a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers may include controlling an optical excitation source and an RF excitation source to apply a pulse sequence comprising two optical excitation pulses and two RF excitation pulses to the NV diamond material, receiving a light detection signal from an optical detector based on an optical signal emitted by the NV diamond material due to the pulse sequence, measuring a first value of the light detection signal at a first reference period, the first reference period being before a period of the light detection signal associated with the two RF excitation pulses provided to the NV diamond material, measuring a second value of the light detection signal at a second reference period, the second reference period being after the period of the light detection signal associated with the two RF excitation pulses provided to the NV diamond material, and computing a measurement signal based on the me

  • Publication number: 20190316335
    Abstract: This invention relates to a ventilated toilet system for removing obnoxious odors from the toilet bowl and includes integral vent channels formed along the base and the back inside of the water tank, and a vent adapter mounted inside the passage that directs the flow of ventilating air along the vent channels to an exhaust pipe and discharges it by a remote in-line exhaust fan to the outside atmosphere. The adapter is attached to the base of the overflow flush valve pipe or, conversely, designed to be an integral part of the overflow flush value pipe, itself, and is positioned to connect the base vent channel of the water tank to the toilet water inlet chamber of the bowl for passage of ventilating air, and to connect the overflow flush valve pipe to the water inlet chamber for passage of flush water.

  • Patent number: 10401392
    Abstract: A thermocouple device includes a shared conductor for a shunt measurement and a thermocouple measurement. For example, the thermocouple device may include a shared conductor that provides a signal to both calculate current of a shunt and calculate a temperature of the shunt. The thermocouple device may provide an efficient structure that accurately calculates current and temperature. In addition, the thermocouple device may use the temperature of the shunt to detect when a conductive path is overheating. The temperature of the shunt may also be used for other purposes.

  • Publication number: 20190205881
    Abstract: Regulated crypto-assets, or blockchain tokens, that are regulated as securities (security tokens) can be purchased using a compliance platform through a compliance wallet that allows token purchasers and token sellers to purchase and sell security tokens in a regulatory compliant manner. A rules engine of the compliance platform determines what compliance rules need to be satisfied for a given transaction and guides the token purchasers through a compliance process. Token sellers, upon being presented with a request to purchase tokens on the blockchain, can verify approved transactions on the compliance platform to ensure that the transaction can be compliantly processed.

  • Publication number: 20190200711
    Abstract: Disclosed is a quick release tool belt for the waist of a user, which includes a support strap, a release band with belt teeth on a first end and a binding with a release mechanism on the second end and slidably coupled to the release band. The binding has a base, a release rotationally attached to the base with a tooth lock, a tooth coupling rotationally attached to the base and engaged with the release and the release band, and a lever rotationally attached to the release and engaged with the release band with a tightening tooth. When the release is in the engaged position the tooth coupling and the lever are engaged with the release band and when the release is in the release position, the tooth coupling is operably engaged with the release and the tooth coupling and the lever are disengaged with the release band.

  • Patent number: 10338162
    Abstract: A system for magnetic anomaly detection is described. The system may include a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers. A controller modulates a first code packet and controls a first magnetic field generator to apply a first time varying magnetic field at the NV diamond material based on the modulated first code packet. The controller modulates a second code packet and control a second magnetic field generator to apply a second time varying magnetic field at the NV diamond material based on the modulated second code packet, wherein the first code packet and the second code packet are binary sequences which have a low cross correlation with each other. The controller determines a magnitude and direction of the magnetic field at the NV diamond material, and determines a magnetic vector anomaly based on the determined magnitude and direction of the magnetic field.
