Patent BR-9910620-A (BR)
Inventor: COLLIER DAVID C
IPC: H04N7/26
Filed: 1999-02-17
Abstract: Methods and devices for detecting a watermark in a watermarked video stream, the watermark having been scaled by an unknown scale among a predetermined finite number of scales and shifted by an unknown number of pixels. For each of the predetermined number of scales, the video stream is divided into a plurality of equally sized scaled watermark blocks; and the plurality of scaled watermark blocks are read into a plurality of read blocks. Each of the read blocks are accumulated into one of a predetermined number of read block bins. The accumulated read blocks are then re-scaled and combined into a single video accumulated block. A predetermined quantity, such as the power of a DCT, is then evaluated within the video accumulated block. This evaluation yields information relative to presence of the watermark in the video stream, the scale applied to the watermarked video and the shift of the watermark, if any, within the watermark blocks. A fractional remainder operation is used to determine the number of read block bins for each scale under consideration as well as to determine the bin into which each read block is to be accumulated.

A valve actuator (20, 130, 220) is provided which includes a gas-generating cartridge unit (22, 22a, 22b, 222) which, upon actuation, generates a charge of high pressure subsonic gas for shifting the gate member (18, 224) at a velocity of about 0.2 to about 0.33 in./msec. Preferably, the actuator includes a piston housing (56, 56a, 56b, 256) having a piston (72, 72a, 72b, 272) therein with a piston rod (71, 71a, 71b, 271) coupled between the piston (72, 72a, 72b, 272) and the gate member (18, 224). In the valve open position, the piston (72, 72a, 72b, 272) is adjacent the cartridge unit (22, 22a, 22b, 222) and is oriented so that the pressurized gas from the cartridge unit (22, 22a, 22b, 222) shifts the piston (72, 72a, 72b, 272) thereby closing the valve (10, 10a, 10b, 124, 146, 212). A dampener unit (99, 299) is provided in a association with the gate member (18, 224) to effect predetermined, controlled deceleration thereof as the gate member approaches its fully actuated position.

Filed: 2000-01-13
Abstract: A set bolt 11 has a head 12 and a shank 14 including a dowel portion 19 and a screw-threaded portion 15. The end remote from the head 12 has a spigot 16 onto which is fitted a collapsible end cap 17. A sheath 18 of a high viscosity anaerobic adhesive extends over the cap 17 and the screw-threaded shank portion 15, being preformed, e.g. by moulding or by extrusion, or being moulded directly onto the bolt 11. When the fastener 11 is inserted into the hole 21 the adhesive sheath 18 engages the bottom of the hole and an axial force on the head 12 displaces the adhesive into contact with the surface of the hole 21. When the adhesive sheath has set, the bolt 11 can be turned in the normal tightening direction to retain a sheet metal component 24. During this tightening the end cap 17 can buckle and the air inside the cap compresses to allow the linear displacement of the bolt 11.

Title: Device for measuring colour and turbidity in a liquid sample
Inventor: HEDGES NIGEL KEITH
IPC: G01N21/85
Filed: 2000-09-29
Abstract: A device for measuring both the colour and turbidity of a liquid sample comprising LED light sources 16 and 40 and reference detectors 44 and 13 to control the output of the LEDs. The reference detectors are used to monitor and correct for fouling of the optical surfaces. Liquid enters the device via sample area 14. Light from the IR LED 16 is scattered off particles suspended in the liquid flowing through the sample area. Light scattered at 90 degrees with respect to the IR beam 17 will be detected by the main detector 30, which measures the turbidity of the liquid. A visible LED 40 also transmits a beam of light 42 through area 14. The main detector 30 further functions to detect the output of the visible LED, and hence the colour of the liquid. The device is intended to be installed in-line in a mains water supply line. The device can be used in domestic water meters or on sewage treatment sites to monitor the effluent discharged back to the river.
