    摘要: An apparatus includes a database with device profiles, and a device programmer. The device programmer includes instructions. The instructions, when read and executed by a processor, cause the device programmer to identify a device identifier of an electronic device. The device programmer is further caused to, based upon the device identifier, access device data from the database. The device programmer is further caused to, based upon the device data, determine an area of memory of the electronic device that can be written. The device programmer is further caused to, based on the determination of the area of memory of the electronic device that can be written, write data to the area of memory.

    摘要: Various embodiments include a switching control method for a three-level flying-capacitor converter. An example method includes sending constant HIGH drive signals to two middle power switches when an input voltage of the converter is lower than a predetermined proportion of a maximum input voltage value. The three-level flying-capacitor converter comprises an input capacitor, a first discharge resistor, a flying capacitor, four power switches, four diodes, an output inductor, and an output capacitor. The two middle power switches consist of the second power switch and the third power switch. The flying capacitor is connected in parallel with the two middle power switches. The HIGH drive signals cause the two middle power switches to be continuously switched on and thereby cause the flying capacitor to be short-circuited.

    摘要: An EtherCAT device is disclosed. The EtherCAT device comprises a data input port to receive a signal representing data, the signal representing one of a plurality of possible logical values; and a degradation calculation circuit. The degradation calculation circuit is to read, demodulate, and convert the received signal into a digital domain representation; process the digital domain representation into slices, where the value of the received signal at a respective time is represented in a respective one of the slices; determine differences between the respective slices and reference slices; identify an intended logical value of the received signal responsive to the determined differences; determine a quantification of error at the respective time responsive to the identified logical value and the determined differences; and determine a signal quality index responsive to the determined quantification of error.

    摘要: A metal-insulator-metal (MIM) capacitor includes a bottom electrode cup, an insulator cup, and a top electrode. The bottom electrode cup includes a laterally-extending bottom electrode cup base, and a bottom electrode cup sidewall extending upwardly from the laterally-extending bottom electrode cup base. The insulator cup is formed in an opening defined by the bottom electrode cup, and includes a laterally-extending insulator cup base formed over the laterally-extending bottom electrode cup base, and an insulator cup sidewall extending upwardly from the laterally-extending insulator cup base. A dielectric sidewall spacer is located between the insulator cup sidewall and the bottom electrode cup sidewall. The top electrode is formed in an opening defined by the insulator cup.
