Title: Vortex shedding flowmeter
Inventor: WEST JAMES LIONEL
IPC: G01F1/32
Filed: 1989-11-23
Abstract: Incoherent light from an LED 8 is launched into a tensioned, multimode optical fibre 2 positioned transversely across a region 6 where fluid flow velocity is to be measured. A photodetector 10 receives light transmitted by the fibre. Vortex shedding causes the fibre to vibrate and set up standing waves. These cause optical bending losses in the fibre and intensity modulation of the light beam. The frequency of modulation is detected by a frequency detector and frequency extracted as an output, 12, to provide a signal proportional to flow velocity. <IMAGE>

Patent GB-2250886-A (GB)
Title: Noise reduction in video signals
Inventor: MILLWARD JOHN DAVID
IPC: H04N5/253
Filed: 1990-12-13
Abstract: In high definition flying spot telecine noise from photomultiplier tubes and afterglow correctors reaches unacceptable levels at high frequencies. The circuit illustrated applies a conventional gamma correction to low frequency components (at 80) but applies a selected non-linear characteristic to the high frequency components (at 74). The characteristic is chosen to provide the optimum noise performance for positive or negative film. The two parts of the signal are then recombined by adders 82. High frequency processing 78 is carried out on a multiplex of the R, G and B components (from 72) to reduce complexity. In other embodiments the gamma correction occurs prior to matrix 72; for other applications the gamma correction may be omitted. <IMAGE>
