Title: Single-use syringe
Inventor: GRAMAGE PINA LOURDES
IPC: A61M5/32
Filed: 2007-01-09
Abstract: Self-disabling or self-locking single-use syringe of the passive type, i.e., one that is self-locked after first use of the syringe, in such a way that any attempted reuse is prevented, and is characterised in that it comprises at least two rings provided on the internal face of the barrel and having the general shape of a circular crown with a variable internal radius, and in that each of the longitudinal fins of the piston has a height which is different from that of at least one of the other fins, in such a way that the plunger can be inserted tightly through the space defined by the variable internal radius of the barrel rings. In this way resistance to the passage of the piston is minimised, thereby reducing the risk of causing bruises, and with a manufacturing cost substantially similar to that of conventional syringes.

Patent CA-2674127-A1 (CA)
Inventor: HUSSAIN SYED
IPC: E21B47/10
Filed: 2007-12-03
Abstract: This invention relates to a process utilizing natural carbon-13 isotope for identification of early breakthrough of injection water in oil wells. All natural water sources are labeled by unique ratios of carbon isotopes (13C/12C). Following the requirements of the invention, the carbon isotope ratio for oil bearing formation water and for local aquifer water which is to be injected in to the oil reservoir rock is determined. The carbon isotope ratio of the produced water from the selected oil wells is then monitored periodically. When the carbon isotope ratio of the produced (oil well) water shows deviation from the formation water value and tends towards injection water value, then the early breakthrough phenomenon of injection water is identified. Thus the contrast in natural carbon isotope ratios of injection water, formation water and produced water from selected oil wells serve as tracer in the identification of "Early Breakthrough" phenomenon of injection water and its movement.

Title: Means for removing unwanted ions from an ion transport system and mass spectrometer
Inventor: MARRIOTT PHILIP
IPC: H01J49/10
Filed: 1999-09-16
Abstract: The present invention relates to inductively coupled plasma mass spectrometry (ICPMS) in which a collision cell is employed to selectively remove unwanted artefact ions from an ion beam by causing them to interact with a reagent gas. The present invention provides a first evacuated chamber (6) at high vacuum located between an expansion chamber (3) and a second evacuated chamber (20) containing the collision cell (24). The first evacuated chamber (6) includes a first ion optical device (17). The collision cell (24) contains a second ion optical device (25). The provision of the first evacuated chamber (6) reduces the gas load on the collision cell (24), by minimising the residual pressure within the collision cell (24) that is attributable to the gas load from the plasma source (1). This serves to minimise the formation, or reformation, of unwanted artefact ions in the collision cell (24).

Abstract: Data retransmission apparatus and method in a wireless relay communication system are provided. It is checked whether an Acknowledgement (ACK) message or a Negative ACK (NACK) message for data is received from a Relay Station (RS), which receives the data from a Mobile Station (MS). Scheduling information for transmitting the data is transmitted to the RS, when the ACK message is received from the RS. Errors are checked for in of the data, when the data is received from the RS. The RS is requested to retransmit the data, when the data has an error. Accordingly, since the RS retransmits only the error-free data to the BS, the BS can enhance the data reliability.

Abstract: This invention is directed to methods and compositions for diagnosis, prognosis and for determining methods of treatment. The physiological status of cells present in a sample (e.g.  clinical sample) can be used in diagnosis or prognosis of a condition (e.g. Chronic Lymphocytic Leukemia), in patient selection for therapy, to monitor treatment and to modify or optimize therapeutic regimens. The physiological status of a cell can be determined by comparing the intracellular status of one or more activation elements (e.g. the phosphorylation status of a signaling molecule) in a cell (e.g. a cancer cell) to that of another cell (e.g.  a normal cell). The physiological status of a cell can be further classified by adding one or more modulators (e.g. an inhibitor or activator) to the cell in question. In some embodiments, the invention is directed to methods of determining a phenotypic profile of a population of cells.

Abstract: A dynamic access control facility that enables an operator to determine whether to grant or deny access to an individual based, in part, on the status of the individual. The operator scans the individual's identification information from an identification record using a scanning device. To determine the status of the individual, the facility decodes the scanned identification information and identifies candidates based on the decoded identification information. The facility may identify a number of candidates or no candidates. For each authorized candidate, the facility selects for display the locations or resources that the candidate is authorized to access. When there is at least one candidate, the facility displays the selected candidate(s) to the operator indicating the status of the individual and/or whether access should be denied or granted. In some embodiments, when no candidates are identified, the facility indicates whether the individual should be denied or granted access.
