20100165788 | ACOUSTIC TRANSCEIVER ASSEMBLY WITH BLOCKING ELEMENT - An acoustic transceiver assembly including a housing, an oscillator, and a blocking element. The housing has at least one inner wall defining a cavity. The cavity has a first end and a second end defining an axis of said acoustic transceiver assembly. The oscillator is provided in said cavity. The oscillator is provided with a transducer element, and a backing mass positioned adjacent to the transducer element. A blocking element is positioned inside the cavity and adjacent to the oscillator. The blocking element is adapted to restrain a portion of said backing mass at a first pressure to thereby restrain the backing mass from lateral movement relative to the axis of the acoustic transceiver assembly. The blocking element is also adapted to release the backing mass at a second pressure. | 07-01-2010 |
20110158050 | WIRELESS NETWORK DISCOVERY ALGORITHM AND SYSTEM - A wireless modem for communication in a network of wireless modems via a communication channel includes a transceiver assembly, transceiver electronics and a power supply. The transceiver electronics include transmitter electronics, receiver electronics and at least one processing unit. The transmitter electronics cause the transceiver assembly to send wireless signals into the communication channel. The receiver electronics decode signals received by the transceiver assembly. The at least one processing unit executes instructions to (1) enable the transmitter electronics to transmit an identification signal into the communication channel, (2) receive data from at least one other wireless modem via the receiver electronics indicative of a unique identifier identifying the other wireless modem, and data indicative of at least one local sensor measurement related to the depth of the other wireless modem below the surface of the Earth, and (3) determine the position and/or relative order of the other wireless modem using the data indicative of the local sensor measurement. The power supply supplies power to the transceiver assembly and the transceiver electronics. | 06-30-2011 |
20120155219 | System and Method for Acoustic Recording in Well Bottomhole Assembly while Firing A Perforating Gun - A sensing and data recording downhole system and method for monitoring of firing of a perforating gun system in a well, including a perforating gun system having charges or bullets for performing well perforation; and one or more downhole recorders and/or one or more fluid detection sensors located above, along, below or in array on the perforating gun system or inside the perforating gun system on a conveyance and configured to at least one of record sound waves generated by explosions of the charges or bullets during the firing of the perforating gun system and detect a presence of fluid within a body of the perforating gun system before and after guns of the perforating gun system are fired. | 06-21-2012 |
