Abstract: A method and apparatus for imparting a positive phase slope (i.e., a negative group delay) to a narrowband signals is disclosed which adjusts the phases of the various frequency components of a signal in a manner opposite to that of a delay line. The invention also permits the amount of phase slope to be adjusted,electronically, without the need for electro-mechanical apparatus or the interchange of cables. Furthermore, embodiments of the present invention are advantageous inthat at the center of the operating band they maintain the phase of the delayed signal. These results are obtained in an illustrative embodiment of the present invention which divides the signal to be delayed into two signals which traverse differentsignal paths (715, 719) and are recombined in a signal combiner (729). The firstsignal path advantageously comprises a gain control block (717). The second signal path advantageously comprises a second gain control block (725) and a fixed linedelay (719) which is not found in the first signal path. The amount of phase slope imparted to the signal can be adjusted by varying the gain (or attenuation) of the respective gain control blocks (717, 725).

Abstract: A monitoring circuit is provided to monitor batteries white they are being charged or discharged, where the batteries comprise a series of modules or cells that are connected in series. A terminal is placed between each adjacent pair of modules and at each end of the battery, so that voltage across each module may be measured at the pair of terminals that define the module. Several different determinations of module voltage may be made during charge and/or discharge of the battery including the resistance free voltage of the module, and the module voltage while current is flowing through the battery. Generally, same or all of the modules are tested periodically, where the interruption interval for internal resistance free voltage determination may be in the order of 2 to 3 ms, and the testing frequency for the battery may be in the order of 0.5 to 25 Hz. Alarms may be triggered in the event of module voltages being sensed that are outside of predetermined limits, meaning that the charging and/or discharging characteristics of any of the modules have changed and are significantly different than those of the other modules. By such alarm indications, the module may be changed before serious damage occurs to the battery, either by overcharging or severely discharging the battery.

Granted: 2000-11-21
Abstract: An apparatus and method for controlling an apparatus for removing tissue from the eye performs various types of corrections using a relatively large beam, but oscillating, or dithering, that being to prevent reinforcing ridges from being formed during the tissue removal process. Further, various types of correction, such as hyperopia and astigmatism correction, are performed using a large beam that is scanned over the area to be ablated using overlapping shots. Further, the epithelium in the area to be treated is removed using an infrared fluorescent dye to dye the epithelium, and then observing the fluorescent patterns from the epithelium area to be removed. Once a certain area is no longer fluorescent after laser shots, smaller shots are then applied, selectively removing the epithelium from the remaining regions. Again, the fluorescence patterns are observed, and the process is repeated until no epithelium remains. At this point, all of the epithelium is removed, and further a map is created of the initial epithelial thickness at each point in the area from which the epithelium was removed.

Abstract: A preprocessor for conditioning interlace-scan video signals for frame based compression, includes apparatus (40) to accept fields of interlace-scanned video and provide fields of interlace-scanned luminance and chrominance component signals.      The fields of interlace-scanned luminance component are combined (45) into respective frames of luminance signal and applied to compressor apparatus for further processing. The fields of interlace scanned chrominance components are independently processed (41,42) at the field level to generate lines of chrominance values which are interstitial to the lines of the original chrominance values and at a lesser pixel and line density. The independently processed fields of interlace-scanned chrominance signals are combined (43,44) into respective frames of chrominance component signals and applied to compressor circuitry (46) for further processing. Performing the chrominance signal interpolation and subsampling (41,42) at the field level tends to eliminate a majority of color distortions around moving images. Receiver apparatus (50) is configured to perform post decompression processing to generate frame data having the original pixel and line density.

The engine can be operated at constant speed or at a partially adjustable speed to maximize engine efficiency and reduce pollution, with one part of the differential speed output power generated throughout the differential mixing drive device being used for driving the load while the remainder of the power is converted through the generator function of the electromagnetic coupling device to charge the battery and thereby increase energy efficiency.
