Title: Low power mode and feedback arrangement for a switching power converter
Inventor: HWANG JEFFREY
IPC: H02M3/155
Filed: 2001-01-31
Abstract: A low power mode and feedback arrangement for a switching power converter. T wo or more main power switches (M1, M2), such as transistors, transfer energy from a supply to load (104) by their opening and closing. When the load (104 ) requires a relatively low power level, this condition is detected. In response, one or more of the transistor switches (M1, M2) is disabled from switching and the reduced power requirements of the load (104) are handled b y the remaining one or more transistor switches (M1, M2). As a result, switchi ng losses are reduced. This is because parasitic gate capacitance and on- resistance associated with the disabled switches no longer consume power fro m the power source. When additional power is required, one or more previously disabled switches (M1, M2) may be brought back into play to ensure that the power requirements of the load (104) are met.

Title: Method for circularizing adenoviral nucleic acid via homologous recombination
Inventor: YOUIL RIMA
IPC: C12N15/861
Filed: 2001-10-05
Abstract: Applicants have identified a process which exploits the bacterial homologous  recombination system to convert double-stranded linear adenovirus genome int o circularized plasmid form (See Figure 4). The system functions via adenovira l terminal fragments present on the plasmid that are less than 500 basepairs each. The result is a plasmid which is more readily analyzed by restriction digestion, PCR, DNA sequencing or used in transient transfection studies. Th e adenovirus plasmids that are generated can be rescued back into virus form. The entire procedure takes 4 days or less instead of the weeks required of plaque purification or dilution cloning isolation techniques. An additional plus of the instant invention is that the disclosed method does not require the use of tissue culture materials or facilities. The disclosed method allo ws for a more extensive and thorough examination of a viral preparation, in tha t it allows for the detection of variants incapable of propagation without the  assistance of co-infecting intact adenoviral genomes. Under standard conditions of plaque purification, these variant genomes are not detected. I t is predicted that far more variant genomes will be observed using the rapid method than would otherwise be detected by standard plaque purification methods.
