PBX compositions and methods for fabricating PBX compositions are provided. In an exemplary embodiment, a PBX composition comprises a binder matrix comprising a thermoset resin and an oxidizer comprising octanitrocubane (ONC), the oxidizer homogeneously dispersed within the binder matrix. In another embodiment, a method for fabricating a PBX composition comprises providing an oxidizer comprising octanitrocubane (ONC) and blending the oxidizer with a prepolymer that, upon cure, forms a thermoset resin.

摘要:
A system includes one or more wireless islands, one or more incident management applications, and one or more message management and routing (MMR) systems. Each MMR systems is configured to act as an intermediary for communication between one of the wireless islands and one or more of the incident management applications. One of the wireless islands includes a radio network. The radio network includes a plurality of remote sensor nodes (RSNs), and a gateway controller. An RSN of the plurality of RSNs is worn by ESS personnel, the gateway controller is mounted to an ESS vehicle, and the RSN is configured to wirelessly communicate with the gateway controller.

A method of securing a container includes inserting, into a seal device at a container, an electronic bolt; reading, by the seal device, a serial number stored in the electronic bolt; communicating, from the seal device, to a user application, insertion of the bolt; scanning, by the user via a handheld device, a barcode on the seal device representative of an identification of the seal device; communicating, from the handheld device to the user application, the identification of the seal device; inputting, by a user at the container via the handheld device, information associated with the container; communicating, from the handheld device to the user application, the information associated with the container; associating, in a database by the user application, the information associated with the container with the bolt serial number and the identification of the seal device; communicating, by the user application, a confirmation to the seal device.
摘要:
RSNs are attached to equipment at construction sites. Gateways located and construction sites. A rental company uses presence data to know in real-time which of multiple yards specific equipment is located for meeting customer needs. At a renter's construction site, a gateway receives engine-hours data from RSNs associated with rental equipment and reports to the rental company, which uses the data to determine whether contract limits on use are exceeded and/or whether the equipment is abused. For sites not having a gateway, a truck-mounted gateway is used to periodically visit and collect data from the RSNs at each site. The data collected is sent to the rental company via cellular link. A construction company uses the system to track and monitor its own equipment in storage yards and on construction sites. Classes are assigned such that a rental company sees only the rented equipment. RSNs send theft and vandalism alarms.
