Abstract: Watch which is controlled electronically and whose housing (1) and display field are in the form of a ring, wherein the watch displays are formed by lighting means (3) and (4) which can be switched such that they circulate on the ring, and wherein at least one annular row of at least 60 light-emitting diodes (LEDs) (16) indicates at least the time parameters of ‘hour’ and ‘minute’, preferably additionally the time parameter of ‘second’, by means of the luminous state of individual LEDs, and an electronic printed circuit board (2) which is used as the annular display field is arranged on one of the ring end faces, and the displays of hours, minutes and seconds differ from one another by virtue of the luminous pattern and/or the luminous colour and/or the brightness and/or the luminous distribution among a plurality of adjacent LEDs.

Abstract: A collaborative engagement system comprises: at least two unmanned vehicles comprising an unmanned air vehicle including sensors configured to locate a target and an unmanned ground vehicle including sensors configured to locate and track a target; and a controller facilitating control of, and communication and exchange of data to and among the unmanned vehicles, the controller facilitating data exchange via a common protocol. The collaborative engagement system controls the unmanned vehicles to maintain line-of-sight between a predetermined target and at least one of the unmanned vehicles.

Abstract: Use of pyrogenic metal oxide for the manufacture of a selfcompacting composition comprising hydraulic binders and having high early strength, the composition comprising at least one hydraulic binder and water as further constituents and the product of the BET surface area, in m2/g, of the pyrogenic metal oxide and the proportion by weight of the pyrogenic metal oxide based on the hydraulic binder being 20 to 200 m2/100 g of hydraulic binder.

Abstract: A software and/or hardware facility for implementing composite applications. The facility includes a composite application designer that enables users to create and modify composite applications. A composite application can include data from primary assets, as well as data from derived assets, which are assets that are derived from one or more primary assets. The composite application designer also enables the creation of configuration files for configuring access to data corresponding to primary and derived assets. The facility also includes a data access service that enables access to data corresponding to primary and derived assets. The data access service is configured by a configuration file that is created by the composite application designer.

Abstract: A device for converting solar energy into process heat has a number of heat xchanging pipes traversing a heat exchanger chamber. A first partial stream of gas to be heated is delivered to inlets of the pipes via an upper distribution chamber, and the first partial stream of gas is subsequently collected from outlets of the pipes in a lower distribution chamber. An inlet aperture of the heat exchanger chamber receives sunlight radiation and a second partial stream of gas to be heated, the second partial stream of gas flowing around the heat exchanger pipes. The heat exchanging pipes absorb the solar radiation and heat both the first partial stream flowing through the pipes and the second partial stream flowing around the pipes. The heated second partial stream is collected by a heated gas outlet conduit connected to the heat exchanger chamber.
