Abstract: The invention relates to a thermal energy storage with at least one thermal energy storage volume. The thermal energy storage comprises at least one primary borehole extending from ground level to a first predetermined depth in a rock body; at least one set of secondary boreholes located around the at least one primary borehole; and at least an upper and a lower fracture plane extending in a radial and/or oblique plane from the at least one primary borehole towards adjacent secondary boreholes. At least one fracture plane permits a hydraulic flow between at least one of the secondary boreholes and the primary borehole. Each thermal energy storage volume is defined by one set of secondary boreholes and its upper and lower fracture planes. The set of secondary boreholes diverge away from the at least one primary borehole at each fractured plane level, without intersecting the at least one primary borehole.

Abstract: The present invention relates to a method for controlling the growth of a plant, the plant being of a predetermined type and arranged in a controlled environment subject to receiving illumination of a mixture of natural and artificial light. The invention also relates to a corresponding system for controlling the growth of a plant and to a computer program product.

Abstract: The present invention relates to a method for determining positions of a plurality of light-emitting devices arranged in a planar grid arrangement, each light-emitting device being individually controllable and having a unique network address. The invention also relates to a corresponding system and to a computer program product.

Abstract: A method for position based management of a plurality of plants being arranged in a controlled environment and subject to light emitted by at least one artificial lighting arrangement. Also, a corresponding mobile electronic device and to a computer program product for position based management of an artificial lighting arrangement arranged to control growth of a plurality of plants in a controlled environment.

Abstract: Random access opportunities are provided to packet data devices needing urgent transmit resources. Additionally, random access opportunities are controlled by prioritizing both the random access opportunities and one or more of the packet data device that needs to transmit or the application data that needs to be transmitted.
