Abstract: A power line communication system and signaling protocol is usable for quick dimming of an electronic ballast. An encoding circuit transmits message frames having encoded control signals across a AC power line. Each of a first set of frames includes a bit pattern corresponding to a lighting zone, and a second set of frames includes hamming-encoded bit patterns corresponding to respective hexadecimal digits of a dimming level for the lighting zone. A ballast in a first (quick-dim) configuration detects the second set of frames, decodes the hamming-encoded digits and immediately adjusts the ballast output to the desired power level. The ballast in a second (normal) configuration determines the desired power level based on a pattern density in the first set of frames, and adjusts the output current of the ballast accordingly. If the ballast of the first configuration fails to detect the second set of frames, it defaults to pattern density recognition.

Abstract: This disclosure is directed to the methods of enhancing hematopoietic stem cells (HSPC) and progenitor cell (HSPC) engraftment procedure. Treatment in vivo of a HSPC donor with compounds that reduce PGE2 biosynthesis or PGE2 receptor antagonists alone, or in combination with other hematopoietic mobilization agents such as AMD3100 and G-CSF, increases the circulation of available HSPCs. Compounds that reduce the cellular synthesis of PGE2 include non-steroidal anti-inflammatory compounds such as indomethacin. Treatment ex vivo of HSPC with an effective amount of PGE2 or at least one of its derivatives such as 16,16-dimethyl prostaglandin E2 (dmPGE2), promotes HSPC engraftment. Similar methods may also be used to increase viral-mediated gene transduction efficacy into HSPC.
