Abstract: Techniques are provided for controlling extraction of landfill gas from a landfill. The techniques include obtaining a measurement of concentrations of oxygen, carbon, and methane in a sample of landfill gas. At least one processor may be used to determine based on the measurement of the concentration of oxygen in the sample, the measurement of the concentration of methane in the sample, and the measurement of the concentration of carbon dioxide in the sample, a balance gas concentration in the sample. Further, the at least one processor may be used to determine whether the determined balance gas concentration in the sample is greater than a balance gas concentration threshold. Responsive to determining that the determined balance gas concentration in the sample is greater than the balance gas concentration threshold, an actuator controls the flow control mechanism to decrease the flow rate of the landfill gas being extracted from the landfill.

Abstract: Techniques are provided for controlling extraction of landfill gas from a landfill. The techniques include receiving user input indicating an upper methane concentration threshold and a lower methane concentration threshold, and obtaining a measurement of the concentration of methane in the sample of landfill gas. At least one processor may be used to determine whether to control an actuator to control the flow control mechanism to adjust the flow rate of the landfill gas being extracted from the landfill. The determining whether to adjust the flow rate may be performed by determining whether the measurement of the concentration of methane in the sample is greater than the upper methane concentration threshold and determining whether the measurement of the concentration of methane in the sample is less than the lower methane concentration threshold. The flow rate of landfill gas being extracted from the landfill may be adjusted based on the determining.

Abstract: Techniques for establishing a data connection are described. In an example, a computer system receives, from a second device of a computer network, first data associated with a first device and second data associated with the second device. The first device is not connected to the computer network. The computer system determines third data generated by one or more devices other than the first device and the second device and associated with at least one of: the first device, the second device, a user account, or the computer network. The computer system generates, based on the first data, the second data, and the third data, a confidence score indicating a likelihood of a user authorization to connect the first device to the computer network. The computer system sends, to the second device based on the confidence score, instructions associated with connecting the first device to the computer network.

Abstract: A method for unlocking and/or locking a privacy lockset from the exterior of the lockset or door and without the use of buttons, keys, or an object inserted into the lockset or door. The operator manipulates a magnetic object, such as a magnet or piece of ferrous metal, on the exterior of the door or lockset to cause an internal magnet attached to a rod to move the rod in and out of a collar, the far end of the rod in turn actuating the lock into a locked and/or unlocked position. Rotational, lateral, and/or thrust forces may be configured to actuate the lock. The invention may apply to rim locks, mortise locks, sliding door locks, cylinder locks, and non-keyed deadbolts.

Abstract: Certain aspects of the present disclosure provide a relatively compact frequency-locked loop (FLL) using a discrete-time integrator. For certain aspects, the FLL also includes a supplemental oscillator and other circuitry that allows for saving the FLL frequency when a reference clock will be disconnected, maintaining a similar frequency during disconnection, and restoring the FLL frequency when the reference clock is reconnected. One example FLL circuit generally includes: an encoder; a combiner comprising a first input coupled to an output of the encoder; a digital-to-analog converter (DAC) comprising an input coupled to an output of the combiner; a discrete-time integrator comprising an input coupled to an output of the DAC; a voltage-controlled oscillator (VCO) comprising a control input coupled to an output of the discrete-time integrator; and a counter comprising an input coupled to an output of the VCO and comprising an output coupled to a second input of the combiner.
