A robot lawnmower includes a body and a drive system carried by the body and configured to maneuver the robot across a lawn. The robot also includes a grass cutter and a swath edge detector, both carried by the body. The swath edge detector is configured to detect a swath edge between cut and uncut grass while the drive system maneuvers the robot across the lawn while following a detected swath edge. The swath edge detector includes a calibrator that monitors uncut grass for calibration of the swath edge detector. In some examples, the calibrator comprises a second swath edge detector.

Techniques are provided that enable a wireless security system that is designed to detect and receive wireless transmissions in one protocol, to use sensor-transmitters that operate in a different protocol. The techniques involve, generally, the use of an integration device, and in some implementations, first enrolling sensor-transmitters of a first protocol into the integration device, along with device type information for the sensor-transmitters. Thereafter, during system operation, transmissions with message packets in the first message packet protocol are received by the integration device, recognized as having been previously enrolled, and a message packet in a second message packet protocol that includes device type information is then formulated and transmitted by the integration device, for receipt by a system control device for the wireless security system. In some scenarios, an enrollment process need not be done in the integration device, and the integration device is utilized in the communication process.

An improved thermal fogging device includes an extended heat transfer surface located within the aerosolization chamber that increases the mixing of the liquid chemical particles and the hot gases in the aerosol to improve aerosolization. The extended heat transfer surface also helps to increase the heat transfer to the forming aerosol in the aerosolization chamber.

An autonomous coverage robot system includes an active boundary responder comprising a wire powered with a modulated current placed along a perimeter of a property, at least one passive boundary responder placed on a property interior circumscribed by the active boundary responder, and an autonomous coverage robot. The robot includes a drive system carried by a body and configured to maneuver the robot across the property interior. The robot includes a signal emitter emitting a signal, where the passive boundary responder is responsive to the signal and a boundary responder detection system carried by the body. The boundary responder detector is configured to redirect the robot both in response to the responder detection system detecting an active boundary responder and in response to detecting a passive boundary responder.

A control system for a power assisted door, the electronic door control system includes an intelligent control, a plurality of sensor inputs operatively connected to the intelligent control, the plurality of sensor inputs associated with state of a plurality of mechanical components of the power assisted door, and a power drive operatively connected to the intelligent control for providing opening and closing of the power assisted door. The intelligent control is configured to monitor status of the plurality of sensor inputs and control the power drive at least partially based on the status of the plurality of sensor inputs. The intelligent control may be adapted to determine when state of the plurality of sensor inputs is indicative of one or more conditions which would preclude safe door movement. A power distribution module may also be present to assist in limiting current draw and to allow for charging.

Control system for power-assisted door

An integrated audio device, such as, for example, a table-top radio, including a housing, a speaker disposed within the housing, a switching power supply disposed within the housing, and audio circuitry disposed within the housing and coupled between the digital switching power supply and the speaker.

A robot lawmnower includes a body, a drive system carried by the body, at least one caster wheel supporting the body, a grass cutter carried by the body, a controller in communication with the drive system, and a bump sensor in communication with the controller. The controller is configured to maneuver the robot to turn in place and to redirect the robot in response to the bump sensor sensing contact with an obstacle. The drive system is configured to maneuver the robot across a lawn and includes differentially driven right and left drive wheels positioned rearward of a transverse center axis defined by the body. The at least one caster wheel is positioned substantially forward of the right and left drive wheels, and the grass cutter is positioned at least partially forward of the right and left drive wheels and at least partially behind the at least one caster wheel.
