Title: High efficiency switching type constant voltage regulator with decreased power consumption
Inventor: LIOU JING-MENG
IPC: H03K7/08
Filed: 1999-03-25
Granted: 2001-05-28
Abstract: This invention is about high efficiency switching type constant voltage regulator with decreased power consumption and includes the followings: an error amplifier; a slanting wave generator; a comparator; a driver (this driver can be omitted if the output current of comparator is large enough); a switch; an inductor; a diode (or using a synchronous rectifying switch); and a capacitor. The characteristic of this invention is to further include a single-one pulse generator and an OR gate (or circuit with the same function) connected between comparator and driver. Therefore, when the whole switching type constant voltage regulator is in the mode of continuously supplying power, it can respond the load variation to quickly adjust the output current and maintain a stable voltage value. When the whole switching type constant voltage regulator is in the mode of non-continuously supplying power, it can supply larger amount of power at one time in order to decrease the number of openings for the switch such that the switching loss of low load is reduced.

Title: Extensional flow mixer
Inventor: STRAND STEVEN R
IPC: B01F5/06
Filed: 1999-10-14
Granted: 2001-08-11
Abstract: An extensional flow mixer for mixing a bulk stream with an additive stream is disclosed. The extensional flow mixer has a generally open and hollow body, having a single entrance port and a single exit port. The path from the single entrance port to the single exit port defines a direction of flow. The generally open and hollow body has a compression region and a broadening region. The compression region includes a plurality of lobes that decrease in the direction of flow. The broadening region includes a plurality of lobes that increase in the direction of flow. The compression region lobes alternate with the broadening region lobes. The bulk stream and the additive stream are introduced at the entrance port of the generally open and hollow body. The streams are compressed by the compression region and broadened by the broadening region as they flow along the generally hollow body, to increase the interfacial area between the bulk stream and the additive stream, and distribute the additive across the flow channel. Additional streams can be introduced externally. The increase in the interfacial area promotes mixing of the bulk stream and the additive stream. The result is an increased rate of incorporation of the additive stream into the bulk stream. The extensional flow mixer is particularly useful in the polymerization process when mixing low viscosity additives, catalysts and monomers with a higher viscosity polymer solution bulk stream.

Inventor: FIELDER LOUIS DUNN
IPC: H04N21/434
Filed: 1999-12-24
Granted: 2001-07-11
Abstract: Blocks of encoded audio information are arranged in frames separated by gaps or guard bands that are aligned with frames of video information. The gaps are provided to protect the audio information against corruption caused by uncertainties or jitter in editing operations such as switching between two difference sources of video/audio information. The otherwise wasted space or bandwidth required to convey the gaps is utilized by conveying encoded segments of auxiliary information. When the encoded auxiliary information is subsequently decoded, an error recovery process provides substitute information for those segments that are corrupted by an editing operation. In one embodiment, the recovery process is adapted according to the choice of an auxiliary sync word conveyed in the segment.

Filed: 2000-06-20
Granted: 2002-01-11
Abstract: A transmission system (14) broadcasts a signal. Within the system (14), a power amplifier (20) causes non-linear distortion. A pre-amp component, such as a band-pass filter (32), causes linear distortion. A high power filter (38) is located downstream of the power amplifier (20) and causes linear distortion. A linear equalizer (42) compensates for the distortion caused by the high power filter (38). A non-linear corrector (44) compensates for the distortion caused by the power amplifier (20), and is located downstream of the linear equalizer (42). A linear equalizer (46) compensates for the distortion caused by the pre-amp components (e.g., 32). The compensating components (42-46) are located upstream of the distorting, pre-amp component (e.g., 32). A interpolation component (22) is located between the three compensating components (42-46) and the distortion causing components (20, 32, and 38) to increase a rate of the signal, such that the compensation occurs at a lower rate of the signal. Signal sampling points (70-74) are located downstream of each distorting component (20, 32, and 38). Sampling selectively occurs at one of the sample points (70-74) for use to update compensation.
