Title: Autonomous interrogating transponder for direct communications with other transponders
Inventor: CHARLOT LINCOLN H JR
IPC: H04Q5/22
Filed: 2006-03-23
Abstract: A group of associated transponders are respectively attached to a plurality of objects, such as sensors or containers. Each transponder includes a memory (16), a transmitter (10), a receiver (12) and a controller (14). The memory (16) stores group data, which includes data related to the respective attached objects. The controller (14) causes the transmitter (10) to autonomously transmit a group interrogation signal and to transmit a response signal in response to receipt of a group interrogation signal from another transponder of the group. The response signal includes at least some of the stored group data. The receiver (12) receives both the group interrogation signals and the response signals from the other transponders of the group. The controller (14) controls the transmitter (10) and the receiver (12) and causes the memory (16) to store data related to the respective object to which the transponder is attached and to store the group data included in the received response signals.

Inventor: ANDERSON DAVID M
IPC: A61K31/60
Filed: 2006-04-14
Abstract: Muscle relaxant formulations which include one or more quaternary ammonium neuromuscular blocking agents have a reduced tendency for hydrolytic degradation, and therefore a longer shelf life stability, when combined with one or more organic anions having at least six carbon atoms and having a pKa of less than 4.0 (preferably ranging from 0.5 to 3.5).

Patent CA-2612144-A1 (CA)
Inventor: FERREIRA GLORIA C
IPC: C12Q1/68
Filed: 2006-06-29
Abstract: Systems and methods for increasing protoporphyrin IX accumulation in a target cell population using aminolevulinate synthase variants. Aminolevulinic acid-mediated photodynamic therapy is a promising approach to treating dysplasic disorders such as cancer and atherosclerosis, but is limited by the lack of a means to deliver optimal quantities of aminolevulinic acid selectively to the target cells, and thereby ensure the best therapeutic response. The disclosed invention provides a means for enhancing the natural production of aminolevulinic acid selectively within target cells to levels predetermined to give an optimal therapeutic response, and is expected to lead to increased efficacy of treatment, possibly broadening the scope of diseases treatable by photodynamic therapy considerably. The disclosed invention is also amenable to patient specific therapy, meaning that a patient's target cells could be used to screen for the aminolevulinic acid delivery system most appropriate for the patient's needs.

Patent CA-2630532-A1 (CA)
Inventor: DAMBRACKAS WILLIAM A
IPC: H04N19/593
Filed: 2006-05-30
Abstract: A video compression encoder which does not require a video frame buffer is disclosed. Without a frame buffer, incoming pixels can not be compared to pixels previously sent to the decoder. Instead, the disclosed encoder only stores check values for groups of pixels sent. If a group's check value has not changed, the encoder sends a command to the decoder not to change that pixel group. Also, without a frame buffer, an incoming video frame can not be captured and later sent to the decoder as network throughput permits. Instead, if throughput is insufficient to send an encoded group of pixels, the encoder leaves the check value for that group unchanged and sends a command instructing the decoder not to change those pixels. This defers updating that group until the next screen update is sent to the decoder. Grouping of pixels can be done in any fashion, for example; a group can be a single video line, a portion of a line, multiple lines or screen rectangles containing portions of multiple lines.
