Patent number: 11935198Abstract: A virtual mailbox is established for a first user based on a virtual mailbox definition specified by the first user. A message directed to the first user is received from a first device associated with a second user. A location within a real-world environment of the first user corresponding to the virtual mailbox is identified. A marker associated with the virtual mailbox is detected within the real-world environment of the first user. Based on detecting the marker, the second device presents the message overlaid on the real-world environment at the location corresponding to the virtual mailbox.Type: GrantFiled: June 29, 2021Date of Patent: March 19, 2024Assignee: Snap Inc.Inventors: Rajan Vaish, Yu Jiang Tham, Brian Anthony Smith, Sven Kratz, Karen Stolzenberg, David Meisenholder

Patent number: 10535982Abstract: A transfer switch and load controller that can be plugged into an existing utility meter socket and electrically positioned between the meter socket and a distribution panel to allow switching between utility power and standby power. The plug-in transfer switch functions to transfer the power supplied to a home between the utility power source and the generator power source upon loss of power from the utility power source. The transfer switch components are contained in an enclosed housing of a meter socket adapter that is mounted directly to the meter socket of a meter housing. The meter socket adapter is prewired to a standby generator such that the standby generator can be connected to a home power system by plugging the meter socket adapter into the meter socket.Type: GrantFiled: July 23, 2018Date of Patent: January 14, 2020Assignee: Briggs & Stratton CorporationInventors: Michael Miller, Gary Gracyalny, David A.

Patent number: 8408882Abstract: A pressure washer system includes an internal combustion engine and a water pump. The internal combustion engine includes an engine block forming a chamber and a cover for the chamber. The cover has an area designed to hold a lubricant. Additionally, the engine includes a crankshaft within the chamber. The water pump includes a pumping mechanism, an inlet, an outlet, and a fluid passage. The pumping mechanism is powered by the crankshaft. Water enters the pump through the inlet and exits the pump through the outlet. The fluid passage extends between the inlet and the outlet. A portion of the fluid passage is formed in the cover of the engine. Heat transfers from the lubricant of the engine to the water of the water pump during operation of the pressure washer system.Type: GrantFiled: October 5, 2009Date of Patent: April 2, 2013Assignee: Briggs & Stratton CorporationInventors: Daniel L.
