The invention relates to a playground comprising a number of pillars of a circular cross sectional area, and a series of playground elements including floor panels and side panels, and a series of brackets for attachment of the playground elements to the pillars. The brackets comprise an element coupling portion adapted to be fastened to a playground element and a pillar coupling portion adapted to be fastened to a side portion of a pillar. Here, the pillar coupling portion comprising a contact face curved to lie against pillar and a boring for receiving a fastening member which is oriented such that the bracket when fastened to the pillar is attached by the fastening member inserted from the bracket and into the pillar in a radial direction of the pillar. The series of brackets comprises brackets with element coupling portions adapted to be fastened to each of the playground elements in the series of playground elements, and all the brackets in the series comprise essentially identical pillar coupling portions such that all the brackets are adapted to be attached to the pillars in the same way. The invention also relates to a method of assembling such a playground. The series of playground elements may include floor panels, side panels, a series of bars of predefined diameters and chains.

A connection system for removably connecting first and second pieces one to another. The connection system comprises: a tapering recess formed in, or connected to, the first piece. The tapering recess has an opening which is shaped and dimensioned to receive a wedge formed in, or connected to, the second piece. The wedge has a dovetail profile which is adapted to engage with walls of the recess. The wedge is shaped and dimensioned to slide in a first direction and thereby wedge into the tapered recess. Each piece has at least one aperture which receives a lock piece. The first and second pieces when connected and which when oriented in a user preferred direction, cause the lock piece to fall from a first aperture into a second aperture, thereby locking the wedge in the tapering recess and preventing movement in an opposite sliding direction.

For economical and energy-efficient use of a PV system having upright, in particular bifacial, PV modules and to substantially avoid shading of the PV modules, a supporting structure which is simple to manufacture and install is provided, that has vertical posts, which are connected to one another at intersecting points, and horizontally running cross-members such that rectangular mounting areas are provided for individual PV modules. The posts and cross-members are formed in a material-saving manner by conventional profiles, and dividing the posts into two interconnectable sections substantially facilitates the assembly. An electrical connection is provided such that active surfaces which are arranged one above another can be operated at different electrical operating points and such that electrical lines are formed which are operated separately from one another and are arranged in a horizontally running manner. This minimizes effects of shading of PV modules on the efficiency of the energy conversion.

A clamp assembly is provided for securing a panel or fairing to an I-beam, and comprises a pair of side blocks and a clamping block, together with a single bolt to secure them in place. Each of the side blocks as an inclined wedge surface, and the T-shaped clamping block has similarly sloped wedge surfaces along the sides of the leg of the T. When a bolt this passed through side legs of the side blocks, and through or under the clamping block, a sliding and wedging action between the inclined and sloped wedge surfaces occurs. Moreover, a clamping action between the top surface of the clamping block and the lower surface of the lower flanges of the I-beam is also induced.

Systems and methods for intelligent data center power management and energy market disaster recovery comprised of data collection layer, analytics/automation/actions layer, energy markets analysis layer. Plurality of data centers employ the systems and methods comprised of a plurality of Tier 2 data centers that may be running applications, virtual machines and physical computer systems to enable data center and application disaster recovery from utility energy market outages. Systems and methods may be employed to enable application load balancing and data center power load balancing across a plurality of data centers may lead to financial benefits when moving application and power loads from one data center location using power during peak energy hours to another data center location using power during off-peak hours.

Examples of first node elements, second node elements, and kits are disclosed. Also, methods for assembling a lattice structure are disclosed. A first node element has a coupling side, the coupling side further having one or more hollow insertion channels, each channel being configured to receive one of the elongated bars, and each channel having a longitudinal axis, and the longitudinal axis of each channel being tilted at an angle with respect to a plane defined by the coupling side. Moreover, the first node element has a contact side, the contact side having an opening, the opening communicating with each of the hollow insertion channels forming a corresponding through-hole such that to form the lattice structure the elongated bars are inserted into the hollow channels from the contact side to the coupling side and traversing the corresponding through-hole.

The holding element consists of at least one holding unit (1), consisting of at least two holding fingers (3) connected with each other on one side at a connecting point (2) and where at the connecting point (2) opposite the holding fingers (3) it has a fastening unit (10) or instead of the fastening unit (10) another holding unit (1) is arranged, where this holding unit (1) likewise consists of at least two holding fingers (3) connected on this side with each other at a connecting point (2) and all holding fingers (3) are preferably fitted with a spherical end (4).
