摘要： This disclosure involves the acetate ester of methyl hydroxypropyl cellulose. This particular cellulose ester is useful as a gelling agent for organic solvents. The methyl hydroxypropyl cellulose acetate is prepared by the simultaneous hydroxypropylation and methylation of cellulose and by the continuation of the cellulose derivatization into acetylation. The overlapping relationship of the hydroxypropylation and acetylation processes is found to be efficient and economical in that it eliminates the difficulty of isolation and recovery of the water insoluble methyl hydroxypropyl cellulose.

摘要： A system and method is provided for providing integrated over-current protection in a switching power supply. In one embodiment, a switching power supply could comprise a gate drive circuit operative to receive a pulse-width modulated (PWM) signal and to drive at least one power field effect transistor (FET) between alternating activated and deactivated states based on a pulse-width of the PWM signal. The switching power supply could also comprise a current sense circuit operative to measure a current associated with the at least one power FET during the activated state. The switching power supply could also comprise a first over-current protection circuit providing a first adjustment to the PWM signal in response to the current being substantially between a first threshold and a second threshold. The second threshold could be greater than the first threshold. The switching power supply could further comprise a second over-current protection circuit providing a second adjustment to the PWM signal in response to the current being substantially greater than the second threshold.

摘要： A partial index availability system places, in a restricted state, all pages in the index associated with a structure modification, when an error occurs in processing a log of the said structure modification. This maintains traversability of the rest of the index that is not in restricted state. The system locates and marks a left sentinel and a right sentinel associated with a non-leaf page that is in a restricted state preventing an undo of a transaction. The sentinels prevent a transaction from accessing an uncommitted change associated with the non-leaf page. After a recovery procedure is run the entire index is made available. During the period between the placement of the index pages in LPL or rebuild pending to the time of final removal of these pages from their restrictive states as a result of a recovery procedure being run, the users are given access to the non-restricted portion of the index.

摘要： A circuit and method for determining overcurrent in a FET detects an output voltage of the FET in both a positive and negative polarity. The related positive or negative currents through the FET can be measured to determine whether an overcurrent condition exists. By measuring positive and negative currents in the FET, the overcurrent detector can obtain twice as much information as when measuring a positive current alone, and can respond more readily to overcurrent conditions. The overcurrent detector avoids the constraints typically observed in cycle-by-cycle PWM control with single polarity Vds sensing, while permitting a relaxation in the timing requirements for current sensing. A spike suppression circuit also contributes to longer sensing intervals.

摘要： A class AD audio amplifier system (10) with DC output detection logic (26) is disclosed. The amplifier system (10) includes multiple audio channels (20), each of which includes a pulse-width-modulator (PWM) (24). The DC detection logic (26) includes a sigma-delta modulator (60) and a digital low-pass filter (62) that monitors the PWM output signals from the PWM modulators (24). The sigma-delta modulator (60) operates at a first clock frequency, while the low-pass filter (62) operates at a much lower clock frequency, so that AC audio components, PWM harmonics, and sigma-delta quantization error is suppressed from the DC detection. The modulated filtered signal is compared against a threshold level (THRSH) to determine whether the amplitude of a DC component at the PWM output is sufficiently high to constitute a fault. If so, a fault detection signal (DC_DET) is issued, and the PWM modulators (24) are disabled to prevent unsafe conditions in the system (10).

摘要： A system and method for concurrency control of hierarchically structured data is provided. Lock requests on a target node are processed by exploiting ancestor-descendant information encoded into prefix encoded node identifiers (IDs). A set of implicit locks on ancestor nodes along a path from an immediate parent of a target node to a root node is derived from an explicit lock request on a target node. A logical lock tree describing existing lock modes for ancestor nodes is consulted to determine compatibility with the derived set of implicit locks. If existing lock modes for ancestor nodes are compatible with the derived set of implicit locks, a lock request on a target node is granted. Otherwise, the lock request is denied. A lock release request follows the reverse process; a target node in a particular transaction is released, as are subsequent locks on its ancestors made by the same transaction.
