Patent CA-2214242-A1 (CA)
Title: Adjustable keyboard support
Inventor: SHAHEEN HANNA
IPC: A47B21/03
Filed: 1997-08-29
Abstract: A height adjustable keyboard support for attachment to and support from a work surface comprising two mounting brackets for attachment to a work surface. A rigid subassembly has a pair of horizontally spaced pivotting support arms rigidly connected at one end thereof by an intermediate member such that said support arms maintain the relationship therebetween. The subassembly is pivotally secured to the work surface by mounting brackets. A tiltable keyboard mounting arrangement is located generally between the support arms and is controlled by a linkage. An adjustable in length link extends between the subassembly and one of the mounting brackets and maintains the subassembly in a desired position and allows adjustment of said position by adjusting the length of the adjustable link. The link can have one end thereof secured in a slot with gravity biasing the link to one end of the slot. The slot allows the keyboard support to move upwardly if required to avoid pinning of an operator's legs therebeneath.

Abstract: A method for adjusting the luminance IMHI of pixels in a high resolution image includes first forming a low resolution image of the original by grouping pixels into superpixels such as 8x8 blocks. A low resolution luminance correction value .delta.LO is determined for each superpixel by comparing the luminance of the superpixel to both a predetermined darkness threshold TD and a predetermined brightness threshold TB. The low resolution luminance correction value .delta.LO is modified to yield .delta.'LO for each superpixel by forming islands of the superpixels and smoothing .delta.LO between superpixels within each island. Finally, a high resolution luminance correction value .delta.HI is calculated for each pixel of the original high resolution image by comparing the luminance IMHI of each pixel to both TD and TB, keeping in mind that .delta.HI is generated through a series of mathematical computations as a function of both the pixel luminance IMHI and the low resolution luminance correction value .delta.LO. Each pixel of the original image is adjusted by the corresponding high resolution luminance correction value .delta.HI and a luminance adjusted image is produced.

Patent CA-2228051-A1 (CA)
Inventor: KLAYMAN ARNOLD I
IPC: H04S1/00
Filed: 1996-07-25
Abstract: An acoustic correction apparatus (20) processes a pair of left and right input signals to compensate for spatial distortion as a function of frequency when said input signals are reproduced through speakers in a sound system. The sound-energy of the left and right input signals (26 and 28) is separated and corrected in a first low-frequency range and a second high-frequency range. T'he resultant signals are recombined to create image-corrected audio signals (27 and 29) having a desired sound-pressure response when reproduced by the speakers in the sound system. The desired sound-pressure response creates an apparent sound image location with respect to a listener. The image-corrected signals (27 and 29) may then be spatially-enhanced to broaden the apparent sound image.

Title: Method of monitoring three phase fluid flow in tubulars
Inventor: THOMPSON LAIRD BERRY
IPC: G01F1/708
Filed: 1997-04-08
Abstract: Multi-phase fluid flow in a pipeline (12) or other flowline is minitored using a combination of flow type detectors. One set of detectors monitors the interfaces between fluid interfaces and the other monitors the presence of different fluid phases around the periphery of the flowline. The relative volumetric fluid flow rates can be measured by detecting changes in the phase interfaces between two sets of sensor rings (14, 16) using sensors (20, 22, 24 and 26) spaced around the flowline with the fluid flow type being detected across the flowline with an annular capacitance detector. The sensors rings typically use ultrasonic transducers (28, 30, 32 and 34) for detecting the phase interfaces while the capacitance device indicates the presence (or absence, of different phases around the periphery of the flowline (12). By combining the outputs of the different detectors, an indication of the flow phenomena in the flowline can be obtained. The flowrate in the line can be measured directly using a concentrically, oriented set of hot wire anemometers or a concentrically oriented set of thermopiles spaced equally around the flowline in conjunction with the annular capacitance device.
