Title: Position error signal control in the presence of defective servo sectors
Inventor: YUN JONG-YUN
IPC: G11B5/596
Filed: 1997-06-19
Abstract: Control means check whether a position error signal (PES) detected from a servo sector is high. The servo sector is marked as defective if the PES exceeds a limit and in this case, servo control is performed using a PES detected from the previous servo sector. Initially, during a self test mode a micro controller scans the PES of each servo sector 42 and compares the PES to a prescribed on-track value. If the scanned PES is within the prescribed value the track number is increased 46 and the process repeated. If the PES is larger than the prescribed value 44 a repeat scan is performed 48 and if the PES is confirmed as too high, a micro controller erases a servo write pattern or marks a pattern on it to indicate a defective servo sector 50.

Patent GB-2329254-A (GB)
Title: Pipe leak detection
Inventor: ASHWORTH ROGER PHILIP
IPC: F16L55/44
Filed: 1998-09-07
Abstract: A pipe leak testing arrangement includes a device 12 having a sealing bags 14 and 15 joined by coupling 16. The bags when inflated form a seal volume chamber 18. The bags may not form a perfect seal and leakage past them could occur when differential pressure is present. The remaining portion of the pipe forms a test volume chamber 19. A transducer 20 measures differential pressure between the chambers and transducer 21 measures the test chamber pressure. Measured pressure information is used by control device to track pressure change and adjust the seal pressure so as to maintain equal pressures even if the test pressure decays due to pipe fracture. If leakage is present in the test volume part of the pipe, the control 25 will then track the test pressure as it falls and so the pressure drop across the band of pressures can be used to give an accurate leakage versus pressure profile. In an alternative arrangement two separate devices with associated circuitry are provided to facilitate two temporary seal pressure chambers with the test chamber therebetween.

Abstract: An inflatable structure comprising a plurality of separate self-contained chambers, and means to inflate/deflate said chambers simultaneously. As shown chambers 1-5 are subdivided into smaller chambers by spring controlled circular air vanes 6-60. Inflation is by operation of a push button mechanism 62 which actuates rotation of the vanes to allow air from a main inlet 61 to flow into all the chambers; release of the push button returns the vanes back to their original vertical position closing the chambers. Deflation is achieved by a similar operation, with the air being released through outlets 63-67. In a further embodiment (Figs 7 and 8), the inflatable chambers take the form of cylinders (1) housing double ended pistons (2,3,4) through which air may be passed for inflation/deflation purposes. Various arrangements (Figs 10 and 11) for preventing egress of gas in the event of a puncture occurring are disclosed, eg the provision of a helium containing float within each chamber. The inflatable structure may for example be a life raft, swimming aid, tent or mattress.

Title: Gas sensor
Inventor: JONDA SVEN
IPC: G01N27/407
Filed: 1999-02-26
Abstract: A gas sensing arrangement, e.g. for monitoring the exhaust channel 9 of an internal combustion engine, includes a gas sensitive element 3 (e.g. an oxygen sensitive strontium titanate sensor) and a layer 2 consisting of a solid electrolyte such as zirconia which carries three electrodes 4, 6 and 7, which may be connected to external circuitry such that a voltage across electrodes 6 and 7 gives a measure of the difference in oxygen concentration across the layer and a current applied through the layer via electrodes 4 and 6 causes oxygen to be pumped through the layer. The circuitry may be arranged such that a current is caused to flow between electrodes 4 and 6 in response to a voltage across electrodes 6 and 7 in such a way as to reduce the voltage to zero and so expose sensor 3 to the same oxygen concentration as in the exhaust channel without exposing the sensor to other components of the exhaust stream. In this way, the layer 2 acts as an oxygen selective filter.
