Patent GB-2332317-A (GB)
Title: Optical network loss-of-signal detection
Inventor: ROBERTS KIM BYRON
IPC: H04B10/08
Filed: 1998-02-10
Abstract: Loss of optical signal is detected in a synchronous communications system by detecting features of a monitor signal occurring at a detection frequency corresponding to the frame rate. Since the frame rate is substantially less than the bit rate, monitoring and detection can be performed at a lower bandwidth than the bit rate. An auto-correlation circuit (17) utilises delays which are an integral multiple of the frame rate and produces a detection value which is compared with a threshold value. Alternatively, detection may be based on a power measurement of a band pass filtered monitor signal by setting the lower bandwidth limit above zero frequency and normalizing the measurement of power relative to an average power measurement. A loss of signal may then be detected by a change in power measurement relative to a threshold and can be used for asynchronous systems as well as synchronous systems. Loss of signal detection may be utilised to control an optical switch (5) to re-route optical signals and generate alarm signals. The use of such detection in all-optical networks avoids the requirement for electronic processing at the bit rate as a means of detection of loss of signal.

Title: Apparatus and method for perforating and fracturing
Inventor: SNIDER PHILIP M
IPC: E21B43/263
Filed: 1995-07-28
Abstract: An apparatus and method for perforating and fracturing subterranean formations to enhance fluid production. At least one unlined punch charge 54 is loaded into at least one punch charge carrier 26, and the void spaces in the punch charge carrier are filled with sand 62. The punch charge carrier is assembled with at least one perforating charge carrier, loaded with at least one perforating charge, and a means for detonation. The assembly is positioned in a well containing a pressurized fluid adjacent the interval to be perforated and/or fractured, and the charges are detonated. The one or more punch charges create one or more apertures in the punch charge carrier, allowing sand to enter the well and be carried by the fluid in the well into the perforations and/or fractures created by the perforating charges and the pressurized fluid. The sand scours and/or props the perforations and/or fractures.

Title: Secure semiconductor device
Inventor: ROLLENDER MATTHEW
IPC: H01L23/58
Filed: 1996-12-12
Abstract: A method for securing confidential circuitry from observation by unauthorized inspection, and a secure circuit immune from unauthorized inspection according to the method. In one embodiment, confidential data or circuitry is placed on a face of separate silicon layers (42, 44), each silicon layer having part of a circuit. Neither silicon layer is intelligible without the other, yet neither can be observed without destroying the other. The two silicon layers are juxtaposed, the face of the first silicon layer (42) flush against and fused to the face of the second silicon layer (44), the confidential circuits on each silicon layer connecting directly with circuits on the other silicon layer without external connectors. Data stored on each face is erased or destroyed when the silicon layers are separated or one of the silicon layers is destroyed. Violence to either silicon layer, or exposure of either silicon layer to light, destroys the data or circuitry on at least one silicon layer of silicon, making the data or circuitry unreadable.
