Patent number: 10237822Abstract: In some embodiments, automatic selective enablement of a wireless interface is provided. In some embodiments, a first device such as a recording device broadcasts a notification via a first wireless interface. The notification may be received by a second device such as a network device, which activates a second wireless interface in response. In some embodiments, the second device may transmit a notification via the first wireless interface to indicate that the second wireless interface has been activated. In response to receiving such a notification, the first device may activate its own second wireless interface in order to complete the connection and transmit a data record to the second device. In some embodiments, the first wireless interface is a low-power wireless interface, and the second wireless interface is a high-power wireless interface.Type: GrantFiled: October 21, 2016Date of Patent: March 19, 2019Assignee: AXON ENTERPRISE, INC.Inventors: Mark A.

Publication number: 20180344117Abstract: A cleaning pad for an autonomous cleaning robot evenly wets and collects debris for cleaning operations. The pad includes a core of absorbent layers for absorbing liquid through capillary action and for distributing the liquid within the cleaning pad. The pad includes a wrap layer around the core, the wrap layer comprising a fibrous layer that is flexible and absorbent, the fibrous layer configured to absorb liquid through capillary action and transfer the liquid to the core. The pad includes one or more transition regions spanning a cleaning width of the cleaning pad, the one or more transition regions dividing the cleaning pad into at least two segments. The forward positioned segment of the pad, of the at least two segments of the pad, has a lesser thickness compared to a thickness of an aft positioned segment of the at least two segments.Type: ApplicationFiled: June 2, 2017Publication date: December 6, 2018Inventors: Marcus Williams, Lin Lung Chieh
