Abstract: Methods for machine velocity change gear selection and shift execution are disclosed. A current velocity and a maximum velocity change for a work machine from the current velocity may be determined. The maximum velocity change may be based on a maximum amount of energy expended to change the velocity of the work machine without exceeding an operational limit of a work machine component. A selected machine velocity change target gear may be a highest one of the available gears that will not cause a difference between the current velocity and an end of shift velocity of the work machine that is greater than the maximum velocity change so that the maximum amount of energy will not be exceeded. Factors affecting the maximum velocity change may include the grade, the mass of the work machine, and a transmission oil temperature.

A first layer of solder enhancing material is positioned on the conductive pad, the first layer of solder enhancing material includes a first region and a second region positioned relative to the first region. A solder member is positioned on the first region of the first layer of solder enhancing material. A second layer of solder enhancing material is positioned on the solder member and on a portion of the second region of the first layer of solder enhancing material. The circuitized substrate may be used in the fabrication of an electronic package.

Abstract: An improvement in a system that includes a group of field units (10, 10A) that each identifies unknown microscopic particles by use of a computer that compares an unknown particle interrogation pattern to the interrogation patterns of a set of known species of particles, which facilitates upgrading of the group of field units. Each field unit is connected by a communication link (84) to a central station (80). The central station can send interrogation patterns of a new species of particle to the field unit computers, which store them in a known-species-particle memory (34) that holds patterns of previously known species of particles. The field unit stores the patterns of unidentified particles in a memory (90) and notifies the central station when it has detected an invasion of a new species.

Abstract: An apparatus for identifying microscopic particles in a fluid, includes a laser beam (16) that passes though a narrow detect zone (22), and photodetectors (30) that detect light scattered by microscopic particles that pass through the detect zone. The laser beam has a horizontal width (W) that is a plurality of times as great as its average vertical thickness (T), to increase the number of particles passing through the zone while minimizing the time of each particle in the zone. A quadrant detector (48) that is used to detect deviation of the laser beam from a predetermined path, is oriented about 45° from the usual direction. The laser beam is generated by a diode laser (82) whose output passes through two appropriately-positioned cylindrical lenses (84, 86) to produce the desired the ratio of width (W) to thickness (T).

Abstract: Methods and systems for encoding data representative of a sequence of video frames for transmission to a decoder. A motion compensated predictive coder (24) substantially losslessly compresses the data, computes a motion vector, and forms an intermediate coded representation which includes the compressed data and the motion vector. A frame detector (26), which detects frames having a prediction error which exceeds a predetermined threshold, is coupled to the motion compensated predictive coder (24). A digital storage device (22) is coupled to the motion compensated predictive coder (24) and the frame detector (26). The digital storage device (22) stores the intermediate coded representation and stores a representation of the frames having the prediction error which exceeds the predetermined threshold. A lossless decoder (29), coupled to the digital storage device (22), substantially losslessly decodes the intermediate coded representation to form a decoded representation.

Abstract: Methods and systems for encoding an audio signal into a bit stream, and for recreating the audio signal from the bit stream are disclosed. In an embodiment of an encoder, a first encoder (10) symbolically encodes a substantially vocal audio signal to form a first encoded signal. A second encoder (12) symbolically encodes a substantially nonvocal audio signal to form a second encoded signal. A multiplexer (14) multiplexes the first encoded signal and the second encoded signal to form the bit stream. In an embodiment of a decoder, a demultiplexer (80) extracts an encoded vocal signal and an encoded nonvocal signal from the bit stream. A first decoder (82) forms a decoded vocal signal based upon the encoded vocal signal. A second decoder (84) forms a decoded nonvocal signal based upon the encoded nonvocal signal. A mixer (86) combines the decoded vocal signal with the decoded nonvocal signal to form the audio signal.
