摘要： A transistor-based full-wave bridge rectifier is suitable for low A.C. input voltages such as received by a Radio-Frequency Identification (RFID) device. Voltage drops due to bridge diodes are avoided. Four p-channel transistors are arranged in a bridge across the A.C. inputs to produce an internal power voltage. A comparator receives the A.C. input and controls timing of voltage boost drivers that alternately drive gates of the four p-channel transistors with voltages boosted higher than the peak A.C. voltage. Four diode-connected transistors are connected in parallel with the four p-channel bridge transistors to conduct during initial start-up before the comparator and boost drivers operate. Substrates are connected to the power voltage on the power-voltage half of the bridge and to the A.C. inputs on the ground half of the bridge to fully shut off transistors, preventing reverse current flow. The transistor bridge can be integrated onto system chips.

摘要： A light-emitting diode (LED) driver provides faster rise and fall times for LED current to reduce image sticking and other interference. A standard DC-DC converter provides a sum current that is slowly ramped up and down by a bypass current digital-to-analog converter (DAC). A digital value to the bypass current DAC is ramped up or down before an LED current is turned on or off. When the LED current is turned on, current is shifted from a bypass path to a path through the LED, maintaining a constant sum current from the DC-DC converter. When a different LED is turned on, current is shifted from one LED's path to the other LED's path. Separate LED current DAC's in each LED path and in the bypass path can share the sum current with digital precision. Using a single DAC for the sum current and switches in each path reduces cost.

摘要： Aspects of the present invention provide a disk-to-disk-to-tape backup method and system responsive to a combined backup request to backup a dataset to a backup disk according to a disk backup schedule and then to backup the dataset from the backup disk to a backup tape according to a tape backup schedule. The combined backup method completes a backup of the dataset to the backup disk and then to a backup tape device in accordance with a resolved schedule that considers potential conflicts between the schedules. To restore, aspects of the invention receive a request to restore a backup of the dataset from a backup-tape and the resolved schedule derived from the tape backup schedule and the disk backup schedule. The restoration verifies that a backup tape holds the target dataset by matching a combined backup identifier from the request against a corresponding combined backup identifier held in storage.

These magnetic force lines have portions that are roughly parallel to the center axis 42 of the discharge electrode 14, the lengths of which parallel portions become longer as the magnetic force lines approach the center axis 42. The two walls 17 and 18 define the scope of the plasma generation region 41 in the dimension of the center axis 42 of the discharge electrode 14. These two walls 17 and 18 are positioned so as to sandwich therebetween the plasma generation region 41 in the dimension of the center axis 42. The plasma generation apparatus is also configured so that the magnetic force lines 43 passing through the center of the plasma generation 41 are shaped so that they do not intersect the two walls 17 and 18.
