A seismic sensor includes a frame, a pendulum pivotably mounted to the frame, a mechanism for sensing angular position of the pendulum, and a monolithic flat spring oriented between the frame and the pendulum for balancing the pendulum at an equilibrium position. The monolithic flat spring includes: (i) an operating region for providing a restoring force to the pendulum proportional to an angular displacement of the pendulum; and (ii) a suspension region for transmitting a force to a portion of the operating region and applying a negligible bending moment to the portion of the operating region.

An improved architecture in a circuit switched communications network is provided in which a plurality of network service provider devices, eg intelligent peripherals are arranged to provide network service data to a plurality of time division multiplex circuits and trunks by converting these circuits and trunks to streams of packets, and providing network service data packetized in a set of network service data packet streams to the circuit packet streams without incurring delays to the circuit packet streams. The circuit packet streams may be duplicated and forwarded to the network service provider devices without incurring delay to the ongoing through put packetized circuits, and similarly packet streams containing network service data may be superimposed into the circuit packet streams, without the requirement for the circuit packet streams to be switched to the network service provider devices. The architecture comprises a plurality of TDM interfaces, a plurality of conversion means for converting from time division multiplexed mode to a plurality of packet streams; a plurality of packet streams switching devices and a plurality of network service provider devices.

A mass positioning apparatus for use with seismic sensors is described. The seismic sensor includes axis mechanics including a pivotable boom with a defined null point. The mass positioning apparatus comprising: adjustment means for positioning the boom at the null point; actuator means for moving the adjustment means; and means for determining a position of the adjustment means relative to an operational range of travel.

A mass position adjustment apparatus for use in a seismic sensor having axis mechanics including a pivotable boom with a defined null point is described. The apparatus comprising: (a) adjustment means for positioning the boom at the null point; (b) actuator means for moving the adjustment assembly; and (c) interface means having hard mineral members for interfacing the actuator means with the adjustment means for reducing occurrences of micro-mechanical movement when the mass position adjustment apparatus is not being operated.

At least one network device that moves storage blocks based upon a session layer or higher protocol set is employed to facilitate communication between at least one host and at least one target storage device. The at least one network device may include a server and a switch. Transactions related to data storage access are expressed in a non-network protocol and transmitted via a network protocol data unit across at least a portion of the network by employing encapsulation. An adapter card associated with the data storage unit is employed to extract the non-network protocol transaction. Multiple, mirrored data storage units that are separated by relatively large physical distance may be employed to reduce the likelihood of catastrophic data loss due to an event such as a fire. Further, READ transactions may be facilitated by preloading data storage units with READ metadata for subsequent transmission to a client device to enable expedited access to data stored on the data storage units.

Applications for networked storage systems

A system and method are provided for regulating incoming traffic to a web site to prevent overload conditions from occurring. The system comprises a capacity determination unit for determining if a web site has additional capacity and a notification unit for notifying customers if no capacity is available. A scheduling processor provides a customer with scheduling options. When the web site has sufficient capacity, a redirect unit redirects the customer to the web site.
