Abstract: Systems and methods of the various embodiments may provide a battery including a rolling diaphragm configured to move to accommodate an internal volume change of one or more components of the battery. Systems and methods of the various embodiments may provide a battery housing including a rolling diaphragm seal disposed between an interior volume of the battery and an electrode assembly within the battery. Various embodiments may provide an air electrode assembly including an air electrode supported on a buoyant platform such that the air electrode is above a surface of a volume of electrolyte when the buoyant platform is floating in the electrolyte.

Abstract: A detonator for initiating a firing of a shaped charge in a gun is configured to include a housing having first and third conducting portions and a second insulating portion, which is sandwiched between the first and third conducting portions; an initiator located fully inside the first conducting portion or the third conducting portion; a first electrical line electrically connecting the initiator to an internal wall of the third conducting portion; and a second electrical line electrically extending from the initiator to the first conducting portion, through the entire second insulating portion.

Abstract: A testing system for a shaped charge of a perforating gun, the testing system including a housing; a casing assembly located inside the housing; a perforating gun having at least one shaped charge, the perforating gun being located within the casing assembly; a sample material located within the housing, and in direct contact with the casing assembly; a wellbore accumulator in direct contact with the casing assembly and configured to supply a first fluid, at a wellbore pressure, inside the casing assembly; and a formation accumulator in direct contact with the sample material and configured to supply a second fluid, at a formation pressure, on the sample material.

Abstract: A hydraulic time delay system and method in a wellbore tool is disclosed. The system/method includes an actuation mechanism which allows pressure to act on a functional piston in the wellbore tool. The movement of the piston is restrained by a partially or filled reservoir which is allowed to exhaust through a flow restriction element. The restriction element comprises standard metal tubing with a known inner diameter and is cut to an exact length as predicted by fluid dynamic modeling. A time delay and rate of piston movement desired for the downhole tool, between a trigger event such as pressure and a functional event, can be tuned with parameters that include the length and diameter of the tubing, reservoir fluid viscosity and number of tubes in parallel. In another embodiment, a secondary plugging element added to the reservoir controls the rate of piston movement and time delay.

Abstract: A monitoring system includes at least one monitoring devices coupled to electrical power distribution system at selected locations for collecting data related to the operation of the monitored system. The monitoring device(s) includes a communication port and processors programmed to segment the collected data into blocks optimized for user analysis operations, encrypt the segmented blocks of data, bundle the encrypted blocks of data with unencrypted metadata that identifies the data blocks by at least the monitoring location at which the encrypted blocks of data were obtained and the type of data, and transmit the encrypted blocks of data with the unencrypted metadata. The system includes at least one client device that has a communication port that is coupled to the monitoring device(s) and the client device and that has a processor programmed to generate and transmit queries regarding selected ones of the encrypted blocks of data.
