Abstract: An apparatus, system and method of operating an autonomous mobile robot having a height of at least one meter. The apparatus, system and method may include a mobile robot body; at least two phased array antennas associated with the mobile body, wherein the phased array antennas enable wireless communication between on-board features of the mobile robot, including at least mobility hardware proximate to a base of the mobile robot body, and off-board sensors related to at least navigation of the mobility hardware; and a processing system communicative with the on-board features and the off-board sensors via intercommunication with the phased antennas, and comprising non-transitory computing code which, when executed by at least one processor associated with the processing system.

Abstract: Apparatus for determining a measurement error of a displacement volumetric meter, the meter having bellows which in use expand and contract to transmit a fluid. The apparatus including a transducer operable to detect movement of the bellows and to generate a signal which varies in accordance with the movement of the bellows; and a computing device in communication with the transducer so as to receive the signal therefrom, the computing device being operable to determine a flow rate of fluid through the meter based on the signal, and to determine a measurement error of the meter based on the determined flow rate. A corresponding method, meter monitoring device and meter measurement error determining device are also disclosed.

Abstract: A heat recovery apparatus comprising a vessel having: a first liquid flow path such that a first liquid can pass through the vessel between a first liquid inlet and a first liquid outlet; a second liquid flow path in thermal contact with the first liquid flow path; and a heater for occasionally heating at least the liquid in the second liquid flow path on an occasional basis. This allows Legionella growth to be inhibited.

Abstract: A heating system in which a warmed fluid is circulated through a delivery network space heaters to provide space heating, further comprising a thermal store and means arranged to circulate the warmed fluid through the thermal store during a heating shut down sequence to recover heat from the warmed fluid.

Abstract: A heating system comprises a heater and a local heat exchange system in which the local heat exchange system comprises: a primary heat exchanger; a heat store having a secondary heat exchanger; a cold water inlet; and a hot water outlet, in which the local heat exchange system is remotely located from the heater, the primary heat exchanger and the heat store are arranged so as to be heated by the heater, and the primary and secondary heat exchangers are in fluid-flow communication with the cold water inlet and the hot water outlet.

Abstract: An optical architecture for a high-energy laser that directs a collimated laser beam through an aperture stop at a desired angle. In one embodiment, the optical architecture includes a single tilt mirror and three stationary mirrors that direct the laser beam in one dimension. The laser beam is reflected off of the mirrors in the same plane and is reflected off of the tilt mirror three times. The first two reflections off of the tilt mirror translate the beam and the third reflection causes the beam to be directed at the desired angle. In another embodiment, the optical architecture includes a single tip-tilt mirror and eight stationary mirrors that direct the beam in two dimensions. The laser beam is reflected off of the mirrors in two planes and is reflected off of the tip-tilt mirror three times. The first two reflections off of the tip-tilt mirror translate the beam and the third reflection causes the beam to be directed at the desired angle.

Abstract: A heat exchanger comprising: gas flow path means for defining a flow path for flue gases from a boiler; liquid flow path means for defining a flow path for a liquid through the heat exchanger; and heat transfer means for transferring heat from the gas in the gas flow path means to the liquid in the liquid flow path means, wherein the heat transfer means forms a first thermal store.

Abstract: An apparatus, program product and method improve management of available computing resources by adjusting use of the resource over a first interval according to actual use of the resource during a second interval. This feature enables a computing resource to exceed its normal limits during the first interval of operation. Use during the second interval may be limited to balance out the burst, or excessive resource usage of the first interval.

Abstract: What I claim is new about my invention is that the double-edged plows on the ends of the plurel to tines (eight as shown) can cultivate and entangle weeds, weed roots and root vines in forward or reverse, will entangle the plural (eight as shown) of tines and double-edged plows with weeds, weed roots and root vines. When a given amount of weeds, weed roots and vines are entangled, stop rotation. Push down Sleeve 7 to have Sleeve 9 cut and push all debris off center pin and tines for removal of the collection of weeds, weed roots and vines.
