摘要:
Disclosed is a power isolation and backup system. When a power fail condition is detected, temporary storage is flushed to an SDRAM. After the flush, interfaces are halted, and power is removed from most of the chip except the SDRAM subsystem. The SDRAM subsystem copies data from an SDRAM to a flash memory. On the way, the data may be encrypted, and/or a data integrity signature calculated. To restore data, the SDRAM subsystem copies data from the flash memory to the SDRAM. On the way, the data being restored may be decrypted, and/or a data integrity signature checked.

摘要:
Methods and systems to measure simultaneously concentrations or concentration ratio(s) of two or more gas ingredients in a sample area comprising: a wavelength modulated light source; an acoustic detector or a photodetector; and means to analyze the signal from the acoustic detector or the photodetector and calculate the concentrations or concentration ratio(s). The light from the light source is transmitted through the sample area. Part of the light will be absorbed in the sample area by the gas ingredients and generates photoacoustic signal. The acoustic detector is used to sample the photoacoustic signal. Alternatively, a photodetector is used to sample the light intensity after the light is transmitted through the sample area.
摘要:
A technique for classifying traffic at a network node involves programming a content addressable memory (CAM) array with multiple class-specific entries, where each of the class-specific entries has an associated traffic class, obtaining a protocol-independent key field from an incoming packet, and searching the programmed CAM array with the protocol-independent key field to identify an associated traffic class of the incoming packet. In another embodiment, each of the class-specific entries has an associated traffic distribution policy, which may be applied to an incoming packet.
摘要:
A method and apparatus for completing call or contacts over a network based upon an identifier. The contacting party sends a message requesting contact with the contacted party, and the system locates the contacted party via a data network or telephone address specified preferably by the contacted party.

A distributed VCC/VSS clamp structure (10) for preventing inadvertent damage to semiconductor integrated circuits caused by an electrostatic discharging event occurring between any two external pins thereof includes a clamp transistor (Q4) which is disposed locally to every ESD protection circuitry associated with each input and output pin of a semiconductor integrated circuit. The clamp transistor is activated so as to provide a secondary discharging path when the direct clamp discharging paths of the ESD protection circuitry are not forming a complete path.
摘要:
A memory comprising apparatus for selecting redundant rows of memory cells wherein the addressing of a defective regular row of memory cells coupled to a first set of bit lines results in the selection of a redundant row of memory cells coupled to a second set of bit lines such that signal interference resulting from the simultaneous enablement of two word lines in the memory is avoided.

Once a purchaser has proceeded through a check out experience with an online retail system, the settings established during that checkout experience will be applied to future checkout experiences by that purchaser. By capturing and thereafter using checkout settings in this manner, a purchaser can proceed from a shopping cart directly to a checkout review page with the checkout review page being pre-populated with such prior established settings. Furthermore, the methodology allows the purchaser to have a virtually unlimited number of goods in their shopping cart and to have multiple different types of order fulfillment options (e.g., shipping, store pickup, delivery to an organization, etc.) automatically established for those goods.
