An endoscope system comprises a scope and a processor. The scope has an imaging sensor, a first image-processing unit that performs primary image processing, a first memory, and a second memory. The first and second memories are non-volatile. The processor has a second image-processing unit that performs secondary image processing, and a processor memory that is non-volatile. The first memory stores an system data that includes parameters for the primary and secondary image processing. The processor memory stores the system data. The second memory is used for storing the system data stored in the processor memory when it is determined that the system data stored in the first memory is older than the system data stored in the processor memory. The system data stored in the second memory is overwritten onto the first scope memory after the system data is stored in the second memory.

An efficient method for compressing sampled analog signals in real time, without loss, or at a user-specified rate or distortion level, is described. The present invention is particularly effective for compressing and decompressing high-speed, bandlimited analog signals that are not appropriately or effectively compressed by prior art speech, audio, image, and video compression algorithms due to various limitations of such prior art compression solutions. The present invention's preprocessor apparatus measures one or more signal parameters and, under program control, appropriately modifies the preprocessor input signal to create one or more preprocessor output signals that are more effectively compressed by a follow-on compressor. In many instances, the follow-on compressor operates most effectively when its input signal is at baseband. The compressor creates a stream of compressed data tokens and compression control parameters that represent the original sampled input signal using fewer bits. The decompression subsystem uses a decompressor to decompress the stream of compressed data tokens and compression control parameters. After decompression, the decompressor output signal is processed by a post-processor, which reverses the operations of the preprocessor during compression, generating a postprocessed signal that exactly matches (during lossless compression) or approximates (during lossy compression) the original sampled input signal. Parallel processing implementations of both the compression and decompression subsystems are described that can operate at higher sampling rates when compared to the sampling rates of a single compression or decompression subsystem. In addition to providing the benefits of real-time compression and decompression to a new, general class of sampled data users who previously could not obtain benefits from compression, the present invention also enhances the performance of test and measurement equipment (oscilloscopes, signal generators, spectrum analyzers, logic analyzers, etc.), busses and networks carrying sampled data, and data converters (A / D and D / A converters).

A rifle scope system allows adjustment of the scope while a shooter maintains the shooting posture and the scope sight picture. The scope system comprises an adjustment system comprising an electromechanical mechanism that responds to a signal from a remote controller manipulated by the shooter without having to significantly disturb the shooting posture. The adjustment system allows the shooter to adjust the scope's point of aim to coincide with a bullet's point of impact at a target. Such adjustment can be performed either by the shooter. Alternatively, such adjustment could be performed by a processor configured to adjust the point of aim based on a ballistic parameter associated with the bullet or the shooting environment. The adjustment system allows such processor-determined adjustments to be effected in a quick manner.

A probe pod housing is connected by a cable to an active probe. The probe pod housing carries a male push-on precision BNC connector that is also a cross-series adapter. The center conductor of the cable receives a male connector that then mates with the non-BNC end of the cross-series adapter. Auxiliary conductors that may also be carried by the cable are connected to male pins (soldered to a circuit board carried within the probe pod) with a push-on female in-line connector. The active probe itself uses a soldered-to-the-shield threaded nut technique. The nut threads into a metallic body that contains the impedance converter and that is enclosed by the body of the active probe.

An enhancement that improves the performance of test and measurement equipment such as digital oscilloscopes and arbitrary waveform generators through the use of compression and decompression is described. The present invention is particularly effective for compressing and decompressing high-speed, bandlimited analog signals that are not appropriately or cannot effectively be compressed by prior art speech, audio, image, and video compression algorithms due to various limitations of such prior art compression solutions. The present invention improves digital oscilloscopes by compressing the sampled version of an analog waveform under observation in real time, allowing a significantly longer duration of the waveform to be stored in the oscilloscope's capture memory, when compared with the duration of the same signal's uncompressed waveform stored in the same memory. Similarly, the present invention improves arbitrary waveform generators by storing a compressed version of a desired arbitrary waveform, instead of the uncompressed version of the arbitrary waveform, in the signal generator's waveform memory. During signal generation, the compressed waveform is decompressed in real time. The uncompressed waveform drives a D / A converter that generates the desired analog waveform. The present invention's simplicity, and its ability to be implemented using parallel compression and decompression elements, allows its use at the high sampling rates of test and measurement instruments. Using the present invention, storage elements in test and measurement equipment can hold significantly longer waveforms in a fixed amount of memory. Users of the present invention can also determine the proper balance between the fidelity and the duration of the decompressed waveform by adjusting various compression and decompression control parameters.
