Abstract: An apparatus may be positioned at the side of a roadway for ensnaring tires of an oncoming land vehicle. The apparatus comprises a base layer further comprising a plurality of receptacles to hold spikes at both lengthwise edges of the base layer. The base layer is adapted to support a net package in a rolled stowed configuration. The net package includes a set of spikes tethered to netting. A deployment hose is connected to the base layer to cause the base layer to become unrolled for deployment when the deployment hose is inflated.

Abstract: A method and system are disclosed for controlling a plurality of perforating gun assemblies arranged in a gun train and lowered into a wellbore. The perforating gun assemblies are connected to a top sub controller that is also lowered into the wellbore. The top sub controller includes a first communications module to communicate with an above-ground control panel via a wireline and a second communications module to communicate with a switch sub in each the plurality of perforating gun assemblies via a network bus. Each switch sub has a unique network address. During assembly, the control panel automatically detects the order of the perforating gun assemblies in the gun train based on polling each of the switch subs of the plurality of perforating gun assemblies using the respective unique network addresses.

Abstract: In networked electronic ordnance systems as disclosed herein, a plurality of pyrotechnic devices communicate with a controller along a common bus. In accordance with an embodiment of the disclosure, at least some of the pyrotechnic devices in the ordnance system are configured such that the address for those devices can be defined during or subsequent to installation of the pyrotechnic devices in an end system. In some instances, a logic device in the pyrotechnic device includes a diagnostics block that initiates a suite of diagnostic tests within the pyrotechnic device in response to a diagnostics command received by the pyrotechnic device. Additionally, in some instances, an additional safety mechanism is added to an energy-reserve capacitor in the pyrotechnic device in compliance with a safe-by-wire standard.

Abstract: A networked electronic ordnance system and method for controlling a variety of pyrotechnic devices at different energy levels include a bus controller controlling at least one pyrotechnic device operating at a first energy level and a smart connector adapting at least one pyrotechnic device operating at a second energy level to control by the bus controller. The smart connector may also include a plurality of capacitors for firing the pyrotechnic device(s). In an embodiment, at least one pyrotechnic device operating at a first energy level and at least one pyrotechnic device operating at a second level include a logic device have a unique identifier. The smart connector may also include an energy reserve capacitor and an emitter follower circuit electrically connected to a logic device. Additionally, the smart connector may be connected to an initiator for firing at least one pyrotechnic device at the second energy level.
