Title: Aggregates in a presence management system
Inventor: PARSONS ERIC W
IPC: H04M11/00
Filed: 2000-11-27
Abstract: A presence management system is described whereby connections between watching parties and watched parties in a multiple access communications network are managed. When the presence management system receives a contact request from a watching party it determines whether the required watched party is available for contact. The system then provides information about this to the watching party who made the request. The presence management system chooses the best mode of communication (e.g. email or fax) taking into account the watched parties preferences and details about the facilities available to the watching party. If, the presence management system informs the watching party that the watched party is unavailable, the watching party is able to set up a monitor.  In determining whether the required watched party is available for contact, the presence management system uses stored information about the watched party, information about the required connection (e.g. size and type) and also rules. In addition, information about events from the multiple access networks are used e.g. geographical location of watched party mobile phones.  Advantageously, watched parties or watching parties are may be groups or aggregates of individuals. Aggregates are treated in the same way as individual watched parties or watching parties. For example, a group of individuals with a common interest may form in order that these watching parties are all informed of a change in the state of one or more watched parties which is relevant to them.

Abstract: We describe a regulated antigen delivery system (RADS) that has (a) a vector that includes (1) a gene encoding a desired gene product operably linked to a control sequence, (2) an origin of replication conferring vector replication using DNA polymerase III, and (3) an origin of replication conferring vector replication using DNA polymerase I, where the second origin of replication is operably linked to a control sequence that is repressible by a repressor. The RADS microorganism also has a gene encoding a repressor, operably linked to an activatible control sequence. The RADS described provide high levels of the desired gene product after repression of the high copy number origin of replication is lifted. The RADS are particularly useful as live bacterial vaccines. Also described is a delayed RADS system, in which there is a delay before the high copy number origin is expressed after the repression is lifted. The delayed RADS is also particularly useful for live bacterial vaccines. Also described are several control elements useful for these systems, as well as methods for providing immunity to a pathogen in a vertebrate immunized with the RADS microorganisms.

Patent CA-2416503-A1 (CA)
Inventor: BITTERLY JACK G
IPC: B01D1/28
Filed: 2001-07-18
Abstract: The present water reclamation system (30) includes a series of concentric thin shells including outer shell (40), intermediate shell (32), and inner shell (34). The shells mount within a housing (50) that can be maintained under vacuum or low pressure. The shells rotate at high velocity. Contaminated liquid from outside the housing is injected into the space between half the shells. The centrifugal force causes the liquid to form a thin film along the inward facing surface of the shell. A compressor (220) lowers the pressure adjacent the thin film causing the liquid to boil. The compressor carries the vapor to the other side of those shells at a slightly higher temperature.  There the vapor encounters the wall, which is cooler because its heat was transferred to boil the contaminated liquid. The vapor condenses, and rotation throws the condensate against the adjacent wall where it is collected. When condensing, the heat of condensation transfers to the shell for boiling the incoming contaminated liquid. The system (30) needs no heat sources other than the energy of vapor compression to complete the cycle flow from vaporization to condensation.
