IPC: G11B20/18
Filed: 2001-04-03
Abstract: A method of verifying defect management area (DMA) information of an optical disc upon initialization with certification, and a test apparatus for performing the same. The method includes generating, as test information, defect management information, which is generated after performing initialization with certification on a test disc, which is obtained by making known physical defects on a blank disc, and verifying the test information using reference test information for initialization with certification to provide the test result.  Accordingly, it can be easily verified that a recording and reproducing apparatus properly translates and processes DMA information which is generated after initialization with certification, using a test disc with known physical defects.

Title: Medical lavage apparatus and methods
Inventor: HOUGHTON WILLIAM R
IPC: A61M3/00
Filed: 1993-07-15
Abstract: A medical lavage apparatus (10) for body cavities comprising a housing (20) having parallel irrigation and aspiration cylinders (28, 32) with captive plungers (24, 26) extending in bores thereof from a first end and pairs of check-valves (102, 106) positioned in parallel, smaller, offset cylinders located at second ends such that reciprocal movement of each plunger in each cylinder performs the function of a one-way pump. The plungers are held captive and aligned by guide-stops (90') proximally disposed in each cylinder. Each plunger comprises a seal (80) disposed at the distal end thereof which inhibits communication between the pairs of check-valves in each cylinder when the plunger is fully seated in the cylinder. Novel jam-free dome shaped, slit check-valves (230) are disposed to be the pair of check-valves in the aspiration cylinder in one embodiment and in irrigation cylinders as well in other embodiments. The dome shaped valves are described for use in other medical fluid control applications, as well. A septum (50) formed of intersecting semi-circular-in-cross-section baffles (58, 60) joins the adjacent outer ends of the irrigation and aspiration check-valve cylinders so as to allow full fluid streams flowing from these outer ends to flow together at an angle. The septum and associated irrigation and aspiration check-valve cylinders are enclosed in a common exchange tube (22) which leads to a common patient tube connecting nozzle. A special patient tube securing attachment (97') is disposed on the connecting nozzle.

Title: System, method and apparatus for cancelling noise
Inventor: MARASH JOSEPH
IPC: G10L25/78
Filed: 2000-02-11
Abstract: A system for cancelling and reducing an audio signal noise arising from electrical or electromagnetic noise sources such as AC to DC power converter used by computers. The system receives a digital audio signal (102) sampled at a frequency which is at least twice the bandwidth of the audio signal. The input samples are stored in a temporary buffer of 256 points (104). when the buffer is full, the new 256 points are combined in a combiner (106) with the previous 256 points to provide 512 input points which are multiplied by multiplier (108) with a shading window with the length of 512 points. The shaded results are converted to the frequency domain through an FFT processor (110). The FFT output is processed in a noise processor (112) which includes the noise magnitude estimation for each frequency bin, the substraction that estimates the noise free complex value for each frequency bin and the residual noise reduction process.

Title: Sleeve for use with a bottle
Inventor: CLARK DAVID W
IPC: B65D55/08
Filed: 1999-12-29
Abstract: A disposable sleeve (20) that can be applied to a water bottle (10) before leaving the filling source and heat-shrunk take the configuration of the upper portion of the bottle including the cap and shoulder and anchor the same to the bottle. Optionally, the cover which has a neck, shoulder and body portion can be provided with a removal tab. Important to the invention, however, is the securing of the sleeve to the bottle in an intimate skin-to-skin relationship which thereby shields the upper portion of the bottle from contamination wherever it may be prior to use. In accordance with the method, the sleeve heat-shrunk to the bottle and is removed prior to emptying the bottle. The bottle is then uncapped and secured to the cooler. The sleeve should not be allowed to touch any portion of the bottle or cooler after its removal.

Abstract: A method of froth flotation includes the steps of providing a fine particulate material, producing a pulp of the material, and contacting the pulp with gas bubbles, generally air, such that a desired phase or component is either selectively attached to the bubbles or selectively left behind in the pulp.      The method is characterised by passing the gas bubbles through a perforated barrier which allows selective passage of the gas bubbles, including gas bubbles to which particles are attached. The perforations will typically be round with a diameter corresponding to between 0,5 and 3 mean bubble diameters, and more typically between 0,8 and 1,5 mean bubble diameters. Generally, the barrier, which may be in the form of a plate, will have a thickness of no less than 1,5 mean bubble diameters and more typically no less than 2 mean bubble diameters.

Title: Method and apparatus for using rf detector and delay circuit to reduce noise buildup in rf return systems
Inventor: KOLBER MARK ALLAN
IPC: H04N7/173
Filed: 2000-04-03
Abstract: This method and apparatus minimizes noise buildup in a wireless or wireline RF return system of a cable television system through which set-top terminals communicate with the cable system headend. An RF detector detects the signal from the set-top terminal to the headend. The RF detector, through a delay circuit, closes an RF switch or turns on a transverter allowing the signal from the set-top terminal to be communicated to the RF return system. The delay circuit prevents the link between the set-top terminal and the return system from being broken for a predetermined period of time after the RF detector stops detecting a signal from the set-top terminal. This prevents delays in transmitting signals, particularly time division multiplexed signals.

Abstract: A broadcast audience measurement system provides a display of the currently recorded audience status on a remote control device located at or near a viewing location from which a broadcast audience member views television programming. Displaying the audience status on a small, viewer-proximate, display, instead of on a separate display next to the television set, allows a broadcast audience research company to use smaller, less obtrusive equipment, thus increasing the likelihood that viewers associated with the statistically selected viewing premises will cooperate with the audience measurement and making their status as members of a research panel less obvious to visitors.

Th e plug extends coaxially with the body run from a first end received internall y therewithin to a second end which extends externally beyond the body second end opening and which is configured to define a third port aligned coaxially  with the first port. The plug is rotatable within the body and is formed as having a first passageway (130) extending through the first and seconds ends  thereof, and at least one perpendicular second passageway (132). The first passageway defines with the first and the third port a first fluid flow path , with the second passageway communicating with the first passageway in defini ng with the first fluid flow path and the second port a second fluid flow path.  The second end of the plug is hand-accessible (124) for the rotation of the plug between a first angular position wherein the second passageway is align ed coaxially with the body branch to open the second fluid flow path, and a second angular position wherein the second passageway is angularly displaced  relative to the branch to close the second fluid flow path. The rotation of the plug is limited by stop surfaces (196a, 196b) on the body and cooperatin g surfaces (193a, 193b) on the plug.
