  • Patent number: 9280412
    Abstract: A non-volatile memory array storing data and ECCs includes error correcting logic. A data set can be read by performing iterations including sensing data using a read bias, and producing an indication of errors in the sensed data. A first iteration uses a first read bias. In each iteration, if the indication in a current iteration is less than a threshold, then the data is output from the selected cells sensed in the present iteration. If the indication in the current iteration exceeds the threshold, then another iteration is performed using a moved read bias, unless the indication in the current iteration shows an increase in errors relative to a previous iteration, in which case then sensed data from the previous iteration is output. Double buffering logic can be used to store sensed data during a current and a previous iteration.

  • Patent number: 9257871
    Abstract: A transfer switch has a mounting seat, and a main no-fuse circuit breaker, an auxiliary no-fuse circuit breaker, a switching control assembly, and a transmission mechanism mounted on the mounting seat. The switching control assembly selectively switches the main no-fuse circuit breaker and the auxiliary no-fuse circuit breaker. The transmission mechanism has a main transmission set and an auxiliary transmission set. When the switching control assembly is switched to form electrical conduction of the main no-fuse circuit breaker, the main transmission set drives the auxiliary transmission set via a transmission rod to prevent electrical conduction of the auxiliary no-fuse circuit breaker from forming. Likewise, when the electrical conduction of the auxiliary no-fuse circuit breaker is formed, the electrical conduction of the main no-fuse circuit breaker cannot be formed. Accordingly, safety of the transfer switch can be improved when switching between power sources.

  • Publication number: 20150364950
    Abstract: An auxiliary excitation device is applied to a generator with a self-excited automatic voltage regulator (AVR). The auxiliary excitation device is installed between a battery and the AVR and constantly monitors the status of output voltage of the generator. When the output voltage of the generator instantaneously drops to a preset variation level, the auxiliary excitation device will convert a DC voltage from the battery into an AC voltage and boost the AC voltage to an auxiliary AC power. The auxiliary power is outputted to the AVR for the AVR to output excitation power to the generator, thereby providing additional excitation power to the generator and raising the output power of the generator.

  • Publication number: 20150129795
    Abstract: The present disclosure relates to a chemical mechanical polishing (CMP) slurry composition that provides for a high metal to dielectric material selectivity along with a low rate of metal recess formation. In some embodiments, the disclosed slurry composition has an oxidant and an etching inhibitor. The oxidant has a compound with one or more oxygen molecules. The etching inhibitor has a nitrogen-oxide compound. The etching inhibitor reduces the rate of metal and dielectric material (e.g., oxide) removal, but does so in a manner that reduces the rate of dielectric material removal by a larger amount, so as to provide the slurry composition with a high metal (e.g., germanium) to dielectric material removal selectivity and with a low rate of metal recess formation.
