  • Patent number: 9675554
    Abstract: Compositions of reagents are formed by forming empty liposomes, mixing the thus-formed liposomes with a sugar solution and a regent, then drying the mixture. The compositions will generally contain less than 10% w/v sucrose. Using this procedure small liposomes are formed with high entrapment efficiency. The process is useful in the production of pharmaceuticals.

  • Patent number: 7877207
    Abstract: A method of obtaining data for use by a receiver of a satellite positioning system or a GNSS comprises deriving the data remotely from the receiver by a server (200), using meteorological information and a regional or global three dimensional map of grid points from which it computes tropospherical delays by ray tracing through the refractivity field derived from atmospheric measurements of pressure, temperature and water data content, such measurements being available from meteorological bodies. When used to enhance position determined by a user receiver that includes a non-meteorological, climate based model (130) giving zenith delays and means (130?) to map them to particular inclinations, the server also includes a copy of such non-meteorological model (230) and provides its ray traced delay values as zenith delays.

  • Patent number: 7427920
    Abstract: A system for monitoring a live population uses a unit as a local data collection device to derive data on the physical condition of a population member. The unit has a local processor for correlating and storing the physical condition data relative to time and a mechanism for transferring the stored data from the local processor to a remote data collection device. The remote data collection device also receives data relating to the location of the population member relative to time, and analyzes the physical condition and location data for unusual events, providing a signal on the occurrence of an unusual event. The physical condition may be derived from a sensor, which is a non-invasive sensor for measuring pulse rate, temperature and oxygen levels. The location data is provided from a locator incorporated in the unit.
