Abstract: A detonation module for a perforation tool is described herein. The detonation module includes a detonator, a switch circuit disposed in a fluid-sealed housing and electrically coupled to the detonator, a shielding circuit coupled to the switch circuit, an annular electrical contact electrically coupled to the switch circuit, and an annular, electrically conductive, compressive member to form a compressive electrical connection with an end of a perforation unit.

Abstract: A method performed by a first network node for selecting a secondary cell for a first wireless device is provided. The first network node configures the first wireless device with a first threshold value relating to a signal quality for determining whether any secondary cell candidate(s) shall be reported to the first network node. The first network node receives a first report comprising a signal quality for secondary cell candidate whose measured signal quality meets the first threshold value. The first network node selects a first secondary cell candidate. The first network node instructs the first wireless device to attach to the first secondary cell candidate. The first network node detects that the first wireless device has failed a first series of random access attempts to the first secondary cell candidate. The first network node configures the first wireless device with a better second threshold value.

Abstract: Embodiments of the present disclosure may provide a perforation tool and method for operating the perforation tool. The perforation tool may include one or more firing heads and one or more gun assemblies. The perforation tool may also include a release mechanism coupled to the one or more firing head and the one or more gun assemblies. The release mechanism may release the one or more gun assemblies to a bottom of a wellbore upon firing of the one or more gun assemblies and maintain the one or more firing heads on the perforation tool.

Abstract: A node of a wireless communication network receives a first request for establishment of a connection between a communication device and the wireless communication network. Upon receiving the first request, the node starts a timer and establishes a context for the connection between the communication device and the wireless communication network. Further, the node receives a second request for establishment of a connection between a communication device and the wireless communication network. Depending on a state of the timer when receiving the second request, the node selects between: A) establishing an additional context for the connection between the communication device and the wireless communication network while maintaining the established context, and B) releasing the established context and establishing a new context for the connection between the communication device and the wireless communication network.
