  • Publication number: 20130322209
    Abstract: Methods and systems for the detection and localization of microseismic events are proposed which operate in real-time. Hypocenters in three spatial dimensions are provided along with an estimate of the event origin time. Sensor positions may be distributed in 3D space, and are not confined to linear arrays in vertical wells. A location of the event is approximated and a grid search, based on the approximate location of the event, is used to derive a residual function over a finer sampling followed by a gradient search of the residual function to optimize the location of the event.

  • Publication number: 20130015871
    Abstract: Systems, devices, and methods for two-sided testing of electronic devices. These systems, devices, and methods may include the use of a test fixture that is configured to electrically connect a back side electrical pad of a device under test with an auxiliary pad that faces in a different direction than the back side electrical pad. Additionally or alternatively, these systems, devices, and methods also may include the use of a probe head that is configured to form an electrical connection with both the auxiliary pad and a front side electrical pad of the device under test. The systems, devices, and methods also may include providing a test signal to the device under test, receiving a resultant signal from the device under test, and/or analyzing the resultant signal.

  • Publication number: 20060240243
    Abstract: The present invention relates to a multilayer polyurea roofing system. An important aspect of the invention is the use of multilayers of polyurea with the base layer having a minimum thickness of 40 mils, thus forming a waterproofing membrane. The multiple layers of polyurea provide increased structural strength, as well as reduce failures caused by applicator error. Moreover, in applications where the polyurethane is applied to insulation board stock, the polyurea membrane is isolated from movements between the base insulation and the roof deck (i.e., wood, metal, concrete decking).

  • Patent number: 6739423
    Abstract: A sleeve for an acoustic logging tool has a structure with a window section having fewer bars than a conventional sleeve separated by a slotted region with thin circumferential slots which are stress-relieved at the ends (“dumb-bell” shaped). Steel receiver mounts are provided for hydrophone pressure sensors and this, together with the axially oriented hydrophones makes the tool less susceptible to interfering vibration.

  • Publication number: 20020107749
    Abstract: In an exemplary embodiment, a network-based method for a user to automatically create a paralleling switchgear system using a product configurator system. The product configurator system is software based and resides on a server and accesses a database storing specific manufacturing requirements of the paralleling switchgear system. The user configures a paralleling switchgear system by using the product configurator to specify system information, an engine generator configuration, and a distributor breaker configuration. The user can lookup a quotation and modify it or can generate a new quotation. The product configurator generates drawings and a price quote based on the user configuration.
