Abstract: A bulkhead assembly for a wind turbine blade is described, wherein a pressure relief conduit is provided at the bulkhead to allow for pressure to equalise across the bulkhead. This helps to prevent faults or cracks in the bulkhead assembly due to differences in pressure on either side of the bulkhead. Furthermore, liquid traps and/or filter media can be accommodated in the conduit to prevent the passage of liquids or other matter across the bulkhead.

Abstract: Examples disclosed herein relate to determination of a power capping signal based on direct memory access. In an example, a hardware timer in a processor may generate a hardware trigger. In response to the hardware trigger, an analog-to-digital convertor (ADC) engine may obtain an analog voltage signal from a server. ADC engine may convert the analog voltage signal to a digital output. ADC engine may then generate a second hardware trigger. In response to the second hardware trigger, a direct memory access engine may provide the digital output to a programmable logic device via a direct memory access (DMA) operation. The programmable logic device may determine a power capping signal based on the digital output, and provide the power capping signal to the server.

Abstract: Some examples relating to managing servers distributed across multiple groups are described. For example, techniques for managing servers it assigning an identified server to a group based on analysis of grouping information associated with the identified server. The grouping information includes an access credential and the group includes a set of severs with each server accessible by a common access credential. Further, the techniques include generating multiple node topology maps for the group based on topology characteristics. Each node topology map corresponds to a topology characteristic and indicates a layout and an interconnection between servers in the group. Also a node topology map is selected based on characteristic of an operation to be executed on the servers in the group. Thereafter, a message including an instruction for executing the operation is communicated to a server based on the selected node topology map.
