  • Patent number: 10472999
    Abstract: Systems and methods for correcting an engine intake camshaft position and an engine exhaust camshaft position for a variable valve timing engine are described. In one example, intake manifold pressure of an engine is sampled while a motor/generator rotates the engine at a predetermined speed without fuel being supplied to the engine. A camshaft angle where minimum intake manifold pressure is observed is a basis for correcting camshaft position.

  • Patent number: 10237822
    Abstract: 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.

  • Publication number: 20190008352
    Abstract: An autonomous floor cleaning robot includes a body, a controller supported by the body, a drive supporting the body to maneuver the robot across a floor surface in response to commands from the controller, and a pad holder attached to an underside of the body to hold a removable cleaning pad during operation of the robot. The pad includes a mounting plate and a mounting surface. The mounting plate is attached to the mounting surface. The robot includes a pad sensor to sense a feature on the pad and to generate a signal based on the feature, which is defined in part by a cutout on the card backing. The mounting plate enables the pad sensor to detect the feature. The controller is responsive to the signal to perform operations including selecting a cleaning mode based on the signal, and controlling the robot according to a selected cleaning mode.

  • Publication number: 20180344117
    Abstract: 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.

  • Publication number: 20180121738
    Abstract: An evidence ecosystem that includes a capture system that detects physical properties in the environment around the capture system and captures data related to the physical properties. The capture system analyzes the captured data in accordance with patterns to detect characteristics and patterns in the captured data. Upon detecting a characteristic or a pattern, the capture system records the identified data and alignment data that identifies the location of the identified data in the captured data. The capture system sends the captured data, identified data, and alignment data to an evidence management system for use in generating reports and producing redacted copies of the captured data for distribution or presentation.
