Abstract: Systems and methods are disclosed to calculate the hue angle of image data. One system includes at least one input channel, an octant determining unit, an angle determining unit, and an angle offset unit. Each input channel receives chroma components of image data. The octant determining unit determines which octant a given image data occupies. The angle determining unit determines a hue angle of the given image data within an octant. The angle offset unit adjusts the hue angle for the image data according to the octant the image data was determined to occupy.

Abstract: A diverter (170, 270) atop the upper wall (110) of a cartridge (100) and over the opening (114, 115) therein avoids direct access of urine to the opening and the sealant (105) within the cartridge. The diverter is spaced by standoffs (182, 282) from the upper wall to provide a urine flow passage. A float (274) can be incorporated in the diverter to provide a visible signal of the presence of collected urine on the cartridge upper wall. A pre-treatment chemically-constituted tablet (210) held by a retainer (200) in the diverter provides sanitizing and/or deodorizing means. Post-treatment chemically-constituted tablets (224a) or pellets (224b) placeable at the outlet of the cartridge protect the drain pipe from corrosion and other harm.

Abstract: In an urine cartridge, equalized pressures and increased flow rate between its inlet and outlet compartments increases the life of the cartridge. The pressure equalizing is effected by placement of a separator between the two compartments to provide them with substantially equal volumes. The increased flow rate is created by a uniquely configured baffle positioned adjacent a pan at the bottom of the cartridge. The baffle configuration is shaped to provide a constriction that increases the flow velocity of the urine so that the fluid flow effects a channel along the bottom pan and through any solids deposited on the bottom pan. A diverter may be placed above the centrally located entry to the inlet compartment to create a circuitous path for preventing a disturbing impingement of the urine onto the sealant contained in the inlet compartment.

Abstract: A tool (120, 220, 320) is engageable with the upper wall (44) of a cartridge (42) and placeable over a diverter (50) which may have been secured to the upper wall. The tool employs fingers (126, 226, 336) which are adapted to engage openings (64, 64a) in the upper wall for enabling the cartridge to be insert into or removed from a urinal (49).

Abstract: Oxygenation of a subject's blood is determined by sensing an absorption spectrum of light directed either invasively or non-invasively into the blood, and then calculating an oxygenation value by evaluating a cost function of the remitted spectrum relative to at least two pre-determined reference absorption spectra representing different, known levels of blood oxygenation. The source of light preferably uses stable, long-life, white LEDs, in which case white-balancing of the remitted spectrum can be accomplished by pre-determining and storing the spectrum of the LEDs, one time for all, and then adjusting the remitted spectrum accordingly to compensate for deviations of the LED spectrum from the constant ideal.

One method is disclosed for converting from a source color space to a target color space. The source color space results from a combination of N primary color points and the target color space resulting from combination of a N+1 or more primary color points in the target color space, wherein N is an integer.

Abstract: Systems and methods are disclosed to effect a gamut conversion of source image data to a target image data set for rendering on a device with possibly a different gamut. One gamut conversion system comprises an input channel means, a gamma unit, a chorma/luma unit, a hue angle calculator, and a gamut conversion unit. The input channel means receives source image data. The gamma unit converts the source image data into perceptually uniform space data. The chroma/luma unit converts the preceptiually uniform space data into a format comprising chroma and luma components. The hue angle calculator receives at least the chroma components from the chroma/luma unit and calculates hue angles for the source image data based on received components. The gamut conversion unit derives gamut conversion values to apply to the components of the source image data using a gamut conversion table.

Abstract: A memory controller and method that provide a read-refresh (also called “distributed-refresh”) mode of operation, in which every row of memory is read within the refresh-rate requirements of the memory parts, with data from different columns within the rows being read on subsequent read-refresh cycles until all rows for each and every column address have been read, scrubbing errors if found, thus providing a scrubbing function that is integrated into the read-refresh operation, rather than being an independent operation. For scrubbing, an atomic read-correct-write operation is scheduled. A variable-priority, variable-timing refresh interval is described. An integrated card self-tester and/or card reciprocal-tester is described. A memory bit-swapping-within-address-range circuit, and a method and apparatus for bit swapping on the fly and testing are described.

Abstract: A liquid flow meter (50), including a microcontroller (60) and associated algorithm, monitors urine flow through a cartridge trap (20). Measuring the duration of such flow and the number of times the urinal is used will determine, in accordance with preset criteria, when servicing or replacement is needed, and alerts a service person to that effect by a warning light (68) or other signal. Because urine has a high mineral content, it is electrically conductive, effective to complete circuits between closely spaced metal contacts (62a-62c, 64a-64c) coupled to the PROM, which allows the manner and existence of the urine to be detected. The liquid flow meter is installed in the cartridge trap by utilizing and placing a split ball stem (52) located at the base of the meter into a mounting hole (42) located in the center of the drain holes (36) on the cartridge cover (26).

Abstract: A dual use roadway or railroad travel vehicle such as a railcar mover (10) which includes an inner set (24) of wheel assemblies (28, 30) designed for alternate roadway or rail travel, together with fore and aft rail wheel assemblies (32, 34) which may be alternately retracted for roadway travel or lowered for rail travel. The wheel assemblies (32, 34) each have a pair of rail wheels (36, 38) mounted spindles (48) so that the rotational axes A of the wheels (36, 38) are oriented at an oblique angle &agr; of less than 6° relative to the horizontal H; this wheel orientation, together with a rail wheel geometry including a rim surface (40, 42) parallel with the associated rotational axis A and a reduced radius of curvature R between the rim surface (40, 42) and the flange (44, 46), significantly decreases the problem of rail wheel climb encountered with conventional movers (10), while also reducing flange wear.

Abstract: An exit opening (78) in a cartridge (22) is alignable with an opening (48) in a housing (32) for communication to an external drain. The cartridge and the housing have positions of final secured and initial unsecured interconnections, when openings (78, 48) are respectively aligned and unaligned. A lever (52) is swivelably secured to the housing bottom wall (46), whose cap (54) can close housing exit tube (28); a projection (56) is engageable with the cartridge for effecting the closure when the housing and cartridge openings (48, 78) are not aligned. Three L-shaped keyways (60) in the housing interior mate with three keyways (82) in the cartridge, and have corrugated surfaces to provide a ratcheted secure connection between the cartridge and the housing when in the secure connection. A tool (92) is used to insert and to remove the cartridge into and from the housing.
