Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, are described for implementing a smart firearm safety device. The safety device attaches to a firearm having a trigger and a slot for receiving a magazine. The safety device includes a locking mechanism that attaches to the trigger to preclude depressing a trigger of the firearm and a sensor that determines an orientation of the firearm or a relative motion of the firearm to indicate detected movement of the firearm. The safety device also includes a radio device that receives parameter signals from the sensor indicating movement of the firearm. The radio device communicates with a component of a property monitoring system to receive a command to engage the locking mechanism to preclude depressing the trigger of the firearm based on parameter signals indicating a particular type of detected movement of the firearm.

Abstract: A method for ceramming a glass article to a glass-ceramic includes placing a glass article into a heating apparatus, and heating the glass article to a first hold temperature at a first predetermined heating rate. The glass article is held at the first hold temperature for a first predetermined duration. The viscosity of the glass article is maintained within log viscosity ±1.0 poise during the first predetermined duration. The glass article is then heated from the first hold temperature to a second hold temperature at a second predetermined heating rate. The glass article is held at the second hold temperature for a second duration. A density of the glass article is monitored from the heating of the glass article from the first hold temperature through the second duration, and the second duration is ended when an absolute value of a density rate of change of the glass article is less than or equal to 0.10 (g/cm3)/min.

Abstract: Systems and techniques are described for pet monitoring during unattended delivery. In some implementations, a monitoring system monitors a property includes sensors located throughout the property and generates sensor data. A monitor control unit receives a first indication that a resident of the property will be receiving a delivery during a delivery time. Based on the sensor data and during the delivery time, the monitor control unit determines that a pet, that resides at the property, has been restrained. The monitor control unit provides, to a delivery person, a second indication that the pet at the property has been restrained.
