Abstract: A method includes receiving, by a monitoring system that is configured to monitor a property and from a visitor to the property, a personally identifying code and a biometric identifier, determining that the personally identifying code corresponds to a stored personally identifying code, receiving, by the monitoring system, location information that corresponds to locations of the visitor during a time period before visiting the property, comparing the biometric identifier to a stored biometric identifier, based on determining that the personally identifying code corresponds to a stored personally identifying code, comparing the biometric identifier to the stored biometric identifier, and the location information, determining a confidence score that reflects a likelihood that the visitor is authorized to access the property, based on the confidence score that reflects the likelihood that the visitor is authorized to access the property, selecting, from among multiple monitoring system actions, a monitoring sy

Abstract: Techniques are described for enabling a service administrator to respond to a detected doorbell press at a property when an authorized user is unavailable to respond. In some implementations, a determination that a doorbell press has been detected at a property is made. Video data collected by a doorbell device of the property is obtained in response to determining that the doorbell press has been detected at the property. Sensor data collected by one or more sensors of a monitoring system located within the property is obtained in response to determining that the doorbell press has been detected at the property. A present security risk for the property is determined based at least on the obtained sensor data and the obtained video data. A communication session between the doorbell device and a server system associated with the monitoring system of the property is established in response to determining the present security risk for the property.

Abstract: Techniques are described for detecting and handling unauthenticated commands in a property monitoring system. In some implementations, a monitoring system may include sensors located throughout a property, a monitoring control unit, and an input device. The monitoring control unit may be configured to receive data collected by the sensors, as well as an input command detected by the input device. For an input command that does not include authentication information, the monitoring control unit may generate property state information based on the sensor data, then analyze the property state data and the input command against one or more rules that relate to authorization of unauthenticated commands. Based on the analysis, the monitoring control unit may determine whether to perform the action corresponding to the input command or whether to perform another action, for example, generating and providing a notification or authorization request to a user.

Abstract: The methods improve the separation of hydrocarbon containing fluids. More particularly, the disclosure is relevant to separating fluids having a gas phase and a hydrocarbon liquid phase using indirect heating. In general, the methods use a first gas separation step followed by indirect heating and then a second gas separation step. Pressure reduction of the hydrocarbon containing fluid occurs either before or after the indirect heating.

Abstract: Techniques are described for managing communications between multiple computing nodes, such as computing nodes that are separated by one or more physical networks. In some situations, the techniques may be used to provide a virtual network between multiple computing nodes that are separated by one or more intermediate physical networks, such as from the edge of the one or more intermediate physical networks by modifying communications that enter and/or leave the intermediate physical networks. In some situations, the computing nodes may include virtual machine nodes hosted on one or more physical computing machines or systems, such as by or on behalf of one or more users (e.g., users of a program execution service). The managing of the communications may include determining whether communications sent to managed computing nodes are authorized, and providing the communications to the computing nodes only if they are determined to be authorized.

Abstract: The methods improve the separation of hydrocarbon containing fluids. More particularly, the disclosure is relevant to separating fluids having a gas phase, a hydrocarbon liquid phase, and an aqueous liquid phase using indirect heating. In general, the methods use a first three-phase gas separation stop followed by indirect heating and then a second three-phase gas separation step. Pressure reduction of the hydrocarbon containing fluid occurs either before or after the indirect heating.

Abstract: A surface-mountable MEMS microphone comprising a MEMS microphone die and an application-specific integrated circuit (ASIC) mounted inside a surface-mountable package housing, and fully enclosed therein. The surface-mountable package is a single, self-contained housing that provides an electrical interface to external circuitry for the enclosed MEMS microphone die and the ASIC, and provides electrical, physical, and environmental protection for the MEMS microphone die and the ASIC. The surface-mountable package allows external acoustic energy to enter the package interior via one or more acoustic ports and impinge on the diaphragm of the MEMS microphone die. The cover of the surface-mountable package comprises an acoustic port with ingress protection to limit dust and particle intrusion. The ingress protection can be a formed member that is part of the cover of the surface-mountable package having various shapes, an internal shield, or a combination of both a formed member and internal shield.

Abstract: Systems and techniques are described for supervising and monitoring the delivery of a package to a property. In some implementations, shipment data indicating a package to be delivered at the property and identification information for a first person is obtained. A request for a second person to access the property and deliver the package that includes identification information for the second person is received. Identification information for the first person is compared to the identification information for the second person. Access to the property is provided to the second person. Sensor data generated by one or more sensors that are located throughout the property and while providing access to the property is obtained and analyzed. A determination of whether the second person delivered the package to the property is made based on analyzing the sensor data. Data indicating the determination is provided for output.

Abstract: Techniques are described for replacing a keypad of an existing security system within a property with a communication-enabled keypad device with dual functioning capabilities as a communicator device and a keypad device. In some implementations, data is received from a security panel of a property. A keypad bus protocol of the security panel is determined based on the data received from the security panel. Sensor data is received from one or more sensors located within the property. A monitoring system command that is not specified within a keypad bus of the security panel is determined based on based on the obtained sensor data. The monitoring system command is converted to a panel command using the keypad bus protocol. The panel command is transmitted on the keypad bus of the security panel.
