Abstract: A method and apparatus for providing useful packet data to a CALEA/Legal Intercept collection function. At an access point to a network such as the Internet, sources and destinations of data connections are examined to determine whether any of the bearer messages should also be routed to a CALEA/Legal Intercept monitoring system. If this condition is recognized, the bearer messages and corresponding signaling control messages are correlated in a call packet delivery application server and then delivered to a CALEA/Legal Intercept monitoring system. Advantageously, the monitoring receives as a bundled message set the bearer message and the control messages used to route and otherwise process these bearer messages.

Abstract: A method and apparatus for supplying cooling air to electronic equipment from ones of at least two sources. A detector detects whether the quality, such as the temperature of the cooling air from a source, is satisfactory and if not shuts the damper to that source and opens the damper to another source. A main controller provides additional control signals for controlling the dampers to protect the electronic equipment, or for shutting down the electronic equipment.

Abstract: The present invention relates to a method for an originator of a voice mail message stored on a voice mail system to modify the message after the session in which the message has ended. An originator initiates a session with a voice mail system, which queries the originator as to the intent of the session. If the session is to record a new message, the voice mail system accepts the message and a unique message identifier is assigned to the message. If the originator wishes to modify an existing voice mail message, the voice mail system requests the originator to supply the unique message identifier. After the message has been identified, the originator is given several options to modify the existing message.

Abstract: A well casing cleaning tool includes a tubular tool body that has a central axial passageway and upper and lower sets of jet ports through the tool body wall. The upper jet ports are angled upward and the lower jet ports are angled downward. The outside diameter of the cleaning tool is slightly smaller than the inside diameter of the well casing to be cleaned. When wash fluid is pumped through the jet ports of the cleaning tool, an area of reduced pressure forms between the upper and lower sets of jet ports. This area of reduced pressure aids in the cleaning of the perforation zone of a well. Bypass passages from above the upper set of jet ports to below the lower set of jet ports prevent a pressure difference between the two sets of jet ports.

Abstract: A technique for efficient use of component placement apparatus used for assembling many different printed circuit boards, wherein all of the printed circuit boards are collectively comprised of more parts than can be handled by a single setup. A portion of the apparatus is dedicated to producing a first family of boards whose identity is determined by their high volume as well as by their parts overlap, while another portion is periodically changed in order to optionally produce different families of boards characterized by their lower volume and lower parts overlap. The changed setups required for the different families of boards are accomplished off-line while the first family of boards is in on-line production.

Abstract: A hydraulic jack of the type typically employed for automotive repair work is equipped with a frame supported on wheels, a hydraulic unit for powering the jack, and an elevator mechanism for raising a lift plate in response to a ram actuated by the hydraulic unit. The hydraulic unit is supported in the frame without bolts or other fastening devices and thus is easily removable for repair or replacement. The elevator mechanism includes pivotable elevator arms for raising a roller which travels along an S-shaped lever. The lever supports the lift plate at one end and is pivoted in the frame at its other end.
