Abstract: An AC backup power system controls a power supply to selectively connect to a primary AC power source or a backup AC power source through a switching module. The switching module is controlled by a monitoring module. The monitoring module has a power monitoring unit, a first circuit switch, a second circuit switch, and a first processor. When the power monitoring unit detects an interruption of primary AC current, the first circuit switch that is normally closed is immediately turned off. The first processor then drives the switching module to connect to the backup AC power source. Once the backup AC power source reaches the zero-crossing point, the second circuit switch is turned on so that the backup AC power source provides power to the power supply. The power supply receives power at the zero-crossing point to avoid problems of sparks and coke deposition.

Abstract: Bacterial live vector vaccines represent a vaccine development strategy that offers exceptional flexibility. In the present invention, genes encoding protective antigens of unrelated bacterial, viral, parasitic, or fungal pathogens are expressed in an attenuated bacterial vaccine strain that delivers these foreign antigens to the immune system, thereby eliciting relevant immune responses. Rather than expressing these antigens using only low copy expression plasmids, expression of foreign proteins is accomplished using both low copy expression plasmids in conjunction with chromosomal integrations within the same live vector. This strategy compensates for the inherent disadvantage of loss of gene dosage (versus exclusive plasmid-based expression) by integrating antigen expression cassettes into multiple chromosomal sites already inactivated in an attenuated vector.
