Title: Air blown optical fiber unit having bead attached on the surface
Inventor: PARK CHAN-YONG
IPC: G02B6/00
Filed: 2007-06-07
Abstract: Disclosed is an air blown optical fiber unit having low friction with an installation tube during air blown installation. The air blown optical fiber unit includes at least one optical fiber, a buffer layer surrounding the optical fiber and made of polymer resin, an outer layer surrounding the buffer layer and made of polymer resin, and beads attached on a surface of the outer layer, and the beads have an average diameter of 80m to 140m and an average roughness of 10m or less and a radio (R/r) of a long radius (R) to a short radius (r) is in the range of 1 to 1.5. The optical fiber unit gives less friction with the inner surface of an installation tube during the installation work, so it may be easily installed not only in a linear region but also in a curved region.

Title: Two part stator cores for downhole permanent magnet motors
Inventor: YURATICH MICHAEL ANDREW
IPC: H02K9/00
Filed: 2004-06-21
Abstract: A downhole permanent magnet motor for a submersible pump has at least three phases and comprises a permanent magnet rotor and a stator bearing phase windings A, B and C in closed slots (2206) in the stator. The stator is made up of first and second concentric parts (2207, 2208) which together define the slots (2206) in the stator so as to permit the phase windings (A, B, C) to be fitted to the first part (2207) prior to fitting of the second part (2208) to enclose the phase windings (A, B, C) within the slots (2206). Furthermore a thermally conductive projection (3110) is provided on one of the concentric parts (2207, 2208) and extends at least part of the way across one of the slots (2206) towards the other of the concentric parts (2207, 2208) to separate adjacent windings in thermal contact with the projection (3110) within the slot. Such a motor construction is advantageous in terms of ease of fitting of the phase windings and in ensuring that the motor has a long life.

Title: Automated response by user radio call tone detection
Inventor: SWIFT RODERICK
IPC: H04H60/32
Filed: 2009-12-11
Abstract: A method for automated response to a user radio, e.g. in `man alone' inaccessible working conditions, comprises detecting a user radio call tone and associating it with a unique radio, generating a response message indicating a check in was received, and transmitting the response message so it can be received by the user radio. Thus, personnel working alone in remote locations have an automated method to periodically check-in, announcing all is well; if check-in is not received at the allotted time, the system automatically generates an emergency response call to designated authorities, for action to aid the worker. The automated method removes the need of a cellular network and can be used with conventional two way radio systems. An associated apparatus comprising plural user radios, a base radio and a base controller is also claimed. Call tone detection may comprise: sampling and filtering an incoming audio signal, resulting in a band limited signal; computing a power spectrum; selecting a highest peak frequency in the spectrum; and selecting a frequency bin to create frequency pulse signatures that are matched with a database of previous pulse signatures.
