Title: Process for the quantification of cell populations or subpopulations and a reagent suitable therefor
Inventor: SCHETTERS HARTMUT
IPC: C12Q1/28
Filed: 1986-11-12
Abstract: A process for quantification of cell populations or subpopulations, by incubating a sample with labelled antibodies directed against characteristic surface antigens of the cell population to be quantified to form labelled antibody/antigen complexes. Standards with known, differing particle concentration and having comparable sedimentation behavior to the cells to be determined and further, carrying molecules which are directed against the labelled antibody or a part hereof are also incubated with the labelled antibodies. The cells of the sample solution, as well as the particles of the standard solution, are separated off from the excess labelled antibodies and the amount of the labelling is measured not only on the cells but also on the particles. By comparison of the measurement value from the sample with the measurement values from the standard solutions, there is ascertained the number of cells to be determined in the sample. The standard and a reagent kit for carrying out the process are also the subject of this application.

Title: Network performance indicators
Inventor: OLIVEIRA MANUEL
IPC: A63F13/12
Filed: 2002-03-14
Granted: 2005-03-16
Abstract: In a set of local terminals (2-5) communicating via a network (6) to constitute a collaborative system (1), each terminal (2) receives data via the network and processes the data to present information via a user interface (9). A network performance monitor (11) determines a network performance parameter representative of performance status of the network in facilitating collaborative communication between the terminals. The network performance monitor outputs the network performance parameter to an output modifier (12) which controls the output generated by a user interface output generator 10 such that the information presented by the user interface to the user is varied according to the value of the network performance parameter for facilitating user perception of the performance status of the network. Where a scene is presented to the viewer, a perceptual metaphor may thereby be conveyed such as to associate fine sunny weather conditions with a good state of well-being of the network and to associate rainy or wintery conditions with a deteriorating state of well-being of the network. The process has application to virtual reality environments allowing interaction between virtual characters controlled by participants each provided with a respected one of the terminals at remote locations served by the network, as in the case of internet based games.
