Abstract: Systems and methods for making and/or using a hybrid laminate composite tube structure. The methods comprise: wrapping a plurality of lamina layers around a male cylindrical tool (e.g., mandrel); treating the lamina layers with heat/pressure to form the hybrid laminate composite tube structure; and assembling a structure by adhesively bonding the hybrid laminate composite tube structure to a metallic fitting. The lamina layers comprise: at least one first lamina layer formed of a first material having a first CTE; and at least one second lamina layer formed of a second material different from the first material and having a second CTE different than the first CTE. The hybrid laminate composite tube structure has at least one property that is different in the axial direction than the hoop direction. An axial CTE of the hybrid laminate composite tube structure is tailored to provide a net zero CTE for the assembled structure.
Abstract: Systems and methods for managing an incident event by a public safety and security organization. The methods comprise: performing Near Field Communication (“NFC”) or Radio Frequency Identification (“RFID”) operations by a Land Mobile Radio (“LMR”) and a field computing device to check-in a field personnel member into an incident event; communicating check-in information to a remote computing device from the field computing device via a packet switched LMR infrastructure or a public network; and using the check-in information by the remote computing device to facilitate management of the incident event by the by public safety and security organization.
