Abstract: A method for anticipation and tracking eye movement for head tracked projectors which divides a projection surface into spherical triangles and uses interpolating calibration values stored at each vertex of the triangle. A calibration map is used that contains information about the relationship between the user's head orientation and where they are looking with their eyes at each calibration point. The projection surface is divided into spherical triangles which are searched to find the triangle which contain the user's interpolated view point by performing a dot product test between the interpolated view point and the unit normal vectors inside the three planes that make up the sides of the spherical triangle extended back to the eye point. When a dot product test fails for any side of the triangle the pointer is followed to the adjacent triangle where the test starts over. When the triangle is found that has the interpolated view point inside it, the selected triangle is divided into three sub-triangles. Then the area of the sub-triangles inside the selected triangle is computed. The areas of the sub-triangles are then used to find ratios of the sub-triangles' areas versus the selected spherical triangle area for weighting the calibration points stored with each vertex. Then the weighted calibrations are added to the values for the interpolated view point. This creates a calibrated view point where the head tracked projector is then pointed and the computer generated simulated image is projected.

Abstract: An input digital audio signal is divided into sub-band signals in respective sub-bands. Scale factors of the respective sub-bands are determined on the basis of the sub-band signals for every frame.       Calculation is made as to differences between the determined scale factors for a first frame and the determined scale factors for a second frame preceding the first frame. Absolute values of the calculated scale-factor differences are calculated, and data representative of the calculated absolute values are generated. The data representative of the calculated absolute values are encoded into data of a Huffman code. Sign bits are generated which represent signs of the calculated scale-factor differences. The subband signals are quantized in response to the determined scale factors for every frame to generate quantized samples of the subband signals. The Huffman-code data, the generated sign bits, and the quantized samples of the sub-band signals are combined into a bit stream.

Abstract: A nozzle assembly allows a metered dose of lubricant to be dispensed. It comprises a housing and a piston assembly. The housing defines a piston bore, a stem bore and a spout, all of which axially aligned. It also defines a lubricant passage, an air inlet, and a channel linked to the inlet. Connectable to a source of lubricant, the passage communicates with the stem bore. Connectable to a source of air, the inlet communicates with the stem bore at a position between the passage and spout. The piston assembly has a piston with stem and a spring. The piston lies in the piston bore, its back communicating with the channel. The protrudent end of the stem protrudes into the stem bore and has a groove defined about its circumference.      The spring biases the piston assembly into a charge position wherein the groove aligns with the passage. This enables the groove to fill with lubricant. When the source of air allows air to act upon the back of the piston, the piston assembly moves against the spring through a transfer position. In this position, the stem extends further into the stem bore so that the groove lies between the passage and inlet. When fully moved against the spring, the piston assembly reaches a discharge position. In this position, the groove communicates with both the inlet and spout. This enables the lubricant to be discharged from the groove and out the spout along with the air from the inlet.

Abstract: A method is provided for rapidly determining whether a load of equipment to be sterilized in a sterilization chamber absorbs, adsorbs, condenses, or decomposes significant amounts of germicide vapor or gas, such as hydrogen peroxide. The initial slope of the curve of a plot of 1n(c/c o) versus time is determined, where c is the concentration of hydrogen peroxide and c o is the maximum concentration of hydrogen peroxide. The initial slope is determined in the first 100 seconds after the maximum in the concentration of hydrogen peroxide. If the initial slope is approximately 0.016 sec-1 or less, the load is acceptable. If the initial slope is significantly steeper than 0.016 sec-1, the load absorbs, adsorbs, condenses, or decomposes significant amounts of hydrogen peroxide. If the slope of the curve is steep, the system can abort the sterilization run before significant amounts of hydrogen peroxide have been absorbed, adsorbed, or condensed.

Title: Gaseous fuel and oxygen burner
Inventor: SESTRAP ARVO M
IPC: F23D17/00
Filed: 2001-06-20
Granted: 2007-04-24
Abstract: No exit-flame burner includes nested elongate mixing and ignition tubes. The mixing chamber tube is of shorter length than the ignition chamber tube and is nested coaxially. The first ends of the ignition and mixing chamber tubes are sealed by a sealing member. A gas port for delivery of oxygen-bearing gas is formed in the sealing member. A gas diffuser is nested coaxially within the mixing chamber tube. A fuel-feeding bore within the gas diffuser is aligned coaxially within the mixing chamber tube. The gas diffuser is shaped as a rhombus in cross-section along the longitudinal axis to thereby define a rim around an apex thereof. The rim extends substantially around, closely adjacent to, a corresponding inside surface of the mixing chamber tube to thereby define an upstream gas plenum upstream of the rim between the rim and the sealing member. In use the burner provides an efficient burn so only heated exhaust gases exit the ignition tube, giving directional control for use of the heat on what may be a small area.

IPC: H04J13/00
Filed: 2001-06-20
Granted: 2009-09-15
Abstract: Use of a training sequence having terms that are orthogonal to each other are employed to considerably speed up execution of the LMS algorithm. Such orthogonal sequences are developed for a channel that is described as a finite impulse response (FIR) filter having a length M new from the already existing orthogonal training sequences for at least two channels that have respective lengths M old1 and M old2 each that is less than M new such that the product of M old1 and M old2 is equal to M new when M old1 and M old2 have no common prime number factor. More specifically, a set of initial existing orthogonal training sequences is found, e.g., using those that were known in the prior art or by performing a computer search over known symbol constellations given a channel of length M. Thereafter, an orthogonal training sequence of length M new is developed, where the product of M old1 and M old2 is equal to M new by repeating the training sequence old1 M old2 number of times to form a first concatenated sequence and repeating the training sequence old2 M old1 number of times to form a second concatenated sequence, so that both the first concatenated sequence and the second concatenated sequence have the same length. Each term of the first concatenated sequence is multiplied by the correspondingly located term in the second concatenated sequence which is placed in the same location in a new sequence made up of the resulting M new products. This new sequence is an orthogonal sequence of length M new.

Filed: 2002-07-09
Granted: 2007-06-12
Abstract: An outboard motor includes an internal combustion engine provided with a pair of intake valves. The opening and closing operation of one of the intake valves can be paused. The internal combustion engine comprises a vertical crankshaft, a cylinder head provided with an intake port having a pair of intake openings for one combustion chamber, and a fuel injection valve for injecting the fuel into the intake port. The intake port has an upper branch section and a lower branch section extended under the upper branch section. A valve train includes a valve-operation mode changing mechanism. The valve-operation mode changing mechanism pauses the opening and closing operation of the first intake valve and operates the second intake valve for opening and closing the lower intake opening of the lower branch section while the internal combustion engine is operating at engine speeds in a low-speed range. Thus, the amount of the stagnant fuel staying on the wall surface of the intake port can be reduced, variation of the air-fuel ratio can be suppressed, and the stability of combustion can be improved.
