A method for self re-encoding an interpreted application includes parsing a string of characters in a comment section of the interpreted application file. Responsive to determining that at least one character of the string of characters is not readable by the target platform, the processor re-encodes the interpreted application file using the string of characters in the comment section. The re-encoding includes parsing a first character in the string of characters. The processor then, optionally, outputs a warning message indicative that a non-native encoding exists in the interpreted application file. The processor parses a second character sequential to the first character. The second character is a first element in a second string of characters indicative of a re-encoding scheme for re-encoding the interpreted application. The processor then outputs a re-encoded application file that is executable by the processor of the target platform.

The present invention discloses methods and systems for providing very high quality audio and video playback using all-digital wireless paths from the source to the speaker transducers, video displays and headphones located anywhere within a distance allowed by the FCC. Each speaker has a separate digital amplifier dedicated to each transducer within it (e.g. woofer, tweeter). The present invention also discloses a system that provides a data link capable of sending an all-digital, full-bandwidth, signal from the original digital source material to each separate transducer in the system without using sound degrading lossy data compression. This system is designed to read, broadcast, and reproduce with accurate audio loudspeaker time-alignment (&#x3c;100 uS) and low overall latency (less than 7 milliseconds) all popular audio and video formats in full-bandwidth and without data compression in the effort to maintain the integrity of the entire audio and video signal.

The device may also include a fan, compressor, turbine or other rotating or reciprocating piece of machinery. In one embodiment, the method features sensing in a first device both a start-up vibration at a start-up time after the first device is affixed to a second device to be monitored and a subsequent vibration level at a subsequent time after the start-up time, and providing both a start-up vibration level signal containing information about the start-up vibration level of the second device, and a subsequent vibration level signal containing information about the subsequent vibration level of the second device; and monitoring in the first device the condition of operation of the second device based on a comparison of the start-up vibration level signal in relation to the subsequent vibration level signal. The apparatus may take the form of one or more modules and/or chipset for performing the steps and functionality of the aforementioned method.

Wireless digital audio/video playback system

A constant-current AC regulator comprises a switching network including two pulse-width modulator (PWM) transistors and two half-cycle transistors, a PWM transistor driver circuit, a main power transformer with two primary windings, a current sensing network, and an electronic control unit. The control unit generates a multiple pulse train signal with pulse widths based on the difference between the instantaneous load current and a predetermined design load current. The PWM transistor driver converts the pulse train signal into voltage signals appropriate for driving the PWM transformers of the switching network. The instantaneous load current is measured by the current sensing network Each set of a PWM transistor plus a half-cycle transistor carries current during a portion, e.g. half of the AC cycle. Only one primary winding is energized at any instant. Each transistor is preferably an IGBT transistor, and each pair of PWM transistor plus half-cycle transistor may comprise a dual IGBT chip. A constant current is expressed by the varying pulse widths with a high number of pulses per cycle. In one embodiment,

Data is transferred from a host system to a subsystem connected to the host by a system bus in an efficient manner using one or more virtual first in first out (FIFO) registers in host memory and a corresponding set of virtual FIFOs located in the subsystem memory. A transmission controller controls the transfer of data from the host FIFOs to the subsystem FIFOs while the subsystem processor reads and processes data from the subsystem FIFO. By accumulating data in the host FIFOs before transfer to the subsystem, overhead associated with starting and stopping data transfers over the system bus is substantially reduced.

An improved non-contact apparatus and method for reading a surface that has information encoded in a relief pattern thereon, includes an optical transmitter for projecting a line of light onto the relief pattern at a first angle to a normal of the surface; an optical receiver that views the projected line of light at a second angle to the normal of the surface and produces signal data that is representative of an image of the reflection thereon. The image viewed by the receiver has parallactic displacements of the line of illumination that occur at transitions between raised and recessed portions of the relief pattern. The signal data is culled such that only those pixels surrounding the line of light are selected. The culled signal data is then decoded into electrical signals which represent decoded information contained in the relief pattern. The optical receiver can be realized as a plurality of light sensors arranged in a linear, or a two dimensional array, together with suitable focusing optics. The optical transmitter can produce either a fan beam of light or sweep a spot of light across the surface. The optical transmitter, optical receiver, the culling, circuit and the decoding circuit contained within either a portable hand-held unit or a fixed mount unit.

In a graphics subsystem, a highly interactive two-dimensional (2D) data stream and a computationally intensive three-dimensional (3D) data stream are processed concurrently in such a manner that processing of the 2D data stream is not held up by processing of the 3D data stream. A 3D geometry subsystem having a parallel pipeline architecture is used to process the 3D data stream, while a 2D subsystem concurrently processed the 2D data stream in parallel with the 3D subsystem. A reordering device couples the processed 2D and 3D data streams to a common raster subsystem. The reordering device, which contains an internal buffer, reorders any order-dependent elements of the 3D data stream appearing at the output of the 3D geometry subsystem in an order different from the order in which they were supplied to the input end. The reordering device prioritizes the 2D data stream relative to the 3D data stream so that elements of the 2D data stream arriving from the 2D subsystem are passed to the raster subsystem almost immediately, without having to wait for elements of the 3D data stream.

Method and apparatus for processing two graphics data streams in parallel

The data processing system includes processing nodes and a graphics display device for processing a graphics data stream. The data processing system partitions a graphics data stream into a data segments or work groups for processing by the processing nodes. Next, the data segments are distributed for processing to the processing nodes. In response to receiving a data segment at a processing node, the data segment is processed to produce a processed data segment. The processed data segments are recombined into a processed graphics data stream. This processed graphics data stream is coupled to the graphics display device.
