Title: Programmable monitoring device for electric consumption
Inventor: RODILLA SALA VINCENTE
IPC: G01R21/133
Filed: 1998-05-08
Abstract: The invention relates to a monitoring device which can monitor automatically and in real time the electric consumption in a house, in premises or any other building while controlling the total consumption of the complete electric installation in a predetermined area, said system comprising means for measuring and indicating the instantaneous consumption, and selection and storage of various consumption levels. All of these operations are governed by control and processing means. There are also provided indicators for the consumed power and means for entering and displaying data so that the user can control the accumulated consumption, set a limit value of the energy cost forecast and send a warning signal when such limit has been exceeded, and additionally prevent any devices from remaining connected when leaving the premises, this being extremely dangerous. The system takes measurements at different points in the installation and makes automatic connections/disconnections of certain loads in order to avoid overcurrents in the electric network.

Title: Method and apparatus for targeted drug delivery into a living patient using magnetic resonance imaging
Inventor: KUCHARCZYK JOHN
IPC: A61M31/00
Filed: 1998-05-15
Abstract: The invention is an apparatus and method for targeted drug delivery into a living patient using magnetic resonance (MR) imaging. The apparatus and method are useful in delivery to all types of living tissue and uses MR Imaging to track the location of drug delivery and estimating the rate of drug delivery. An MR-visible drug delivery device positioned at a target site (e.g., intracranial delivery) delivers a diagnostic or therapeutic drug solution into the tissue (e.g., the brain). The spatial distribution kinetics of the injected or infused drug agent are monitored quantitatively and non-invasively using water proton directional diffusion MR imaging to establish the efficacy of drug delivery at a targeted location.

Patent CA-2292320-A1 (CA)
Inventor: DONALDSON ALAN
IPC: G02B6/34
Filed: 1999-12-06
Abstract: A design of expanded-beam type wavelength multiplexer or channel drop and insert filter using oblique light incidence upon a concatenation of substrate mounted dielectric filters involves mounting the beam-expanding graded-index lenses in pre-aligned V-grooves, and only later securing fibres to those lenses. This approach simplifies component alignment problems by reducing the number of degrees of freedom and, by virtue of the fact that the mechanical design allows implementation using minimal amounts of adhesive, provides long-term stability of optical performance.

Title: Method and system for routing calls to wireless directory numbers in a network
Inventor: BRENNAN STEPHEN P
IPC: H04W76/02
Filed: 2000-06-29
Abstract: Methods and systems are provided for establishing calls to wireless directory numbers (DNs) in a telecommunications network (200). When a call is directed to a wireless DN, a first node in the network identifies a signaling node (220) associated with the wireless DN and sends the identified signaling node (220) a request for a route to the wireless DN. If the wireless device associated with wireless DN  is outside of its home area and is served by a visited node in the network, the signaling node (220) determines a route that excludes the home node associated with the wireless DN and returns a temporary location directory number (TLDN) to the first node. Using the TLDN, the first node then establishes a connection to the visited node.
