Abstract: The stabilizing support device for cake fireworks is a device used to provide users with a supporting platform for fireworks, that prevents firework cakes from flipping over and causing unnecessary injuries. To accomplish this, the device includes a stable platform and a plurality of fastening means. Preferably, the device may hold a plurality of cake fireworks and may launch fireworks separately or all together. The device can further ignite the firework electronically through wireless communication. This can improve firework shows for everyday consumers can bring a backyard firework show to a professional firework display level. Furthermore, the device includes support stands that have the capabilities to shoot the fireworks in multiple angles and multiple heights. This can help families who have very little knowledge on how to put together a proper firework show. Additionally, the device can also be folded and fit into a small size carryon bag.

Abstract: In some implementations, systems and techniques are described to automatically unlock a front door of a property in response to detecting an alarm signal indicating an emergency at or near a property. Data indicating occurrence of an emergency condition at a property is initially obtained. A lock configuration for an electronic lock of the property is determined. An unlock instruction is generated for the electronic lock based on the determined lock configuration for the electronic lock. The unlock instruction is transmitted to the electronic lock such that, when the unlock instruction is received by the electronic lock, the electronic lock is unlocked according to the unlock instruction.

Abstract: An annular tube (or other shape) of elastomeric cellular material comprising elastomeric closed cells having gas infused therein is supported by structures protruding from the bottom surface of a suction stabilizer's head and/or by structures within the interior volume of the annular body of the suction stabilizer, preferably with spacing between the outer diameter of the annular tube of the cellular material and the inner walls of the suction stabilizer body. The gas-infused closed cell material may thus be employed in new suction stabilizer or pulsation dampener or to retrofit existing suction stabilizers or pulsation dampeners designed for a gas-filled bladder.

Abstract: Techniques are described for determining that a property is vacant based on monitoring data collected by connected sensors and appliances near or within the property. In response to determining that a property is vacant, the condition of the vacant property can be monitored for various risks such as fire safety and security breaches. Monitoring techniques may also be used to determine when a new customer (e.g., a new tenant or property owner) has moved into the property. In response to detecting a move-in, one or more notifications may be transmitted to assist the new customer to customize a security system associated with the property. In this regard, techniques described herein may be used by service providers to improve the transition associated with move-in and move-out processes, which may also improve retention of monitoring services.
