Abstract: In a medical meassuremnet system, measurements can be carried out at a distance from a hospital. Thus the patient is connected to a measuring system comprising measuring sensors and a unit for collecting data comprising a transmitter. The system also comprises a centrally located surveillance unit. The measuring sensors sense various physical and physiological parameters, for example brain activities, actions of the heart, respiration, blood pressure, blood values/tests and body movements. The sensed signals are transmitted to a portable small device of low weight for collecting and/or analyzing data, which is connected to a central surveillance unit, for example via the public switched telephone network (PSTN), a radio system, in particular a cellular radio system, or via a satellite communication. In a preferred embodiment the measuring sensors comprise a preamplifier having an identification circuit. The identification circuit is used for providing each preamplifier with a unique identity.

Abstract: For monitoring and estimating a person's wakefulness, a stationary pressure sensor contacts part of that person's body and generates a signal corresponding to that person's body movements relative to the sensor. A detector/filter circuit connected to the sensor separates signals corresponding to true body movements, heartbeat-related body movements, and respiration-related body movements. Calculation and comparison circuits are adapted to receive these signals and compare them with previously received signals to determine possible changes. A correlator correlates the output signals from the calculation and comparison circuits to produce a resulting change signal which is compared with a preset wakefulness threshold in a threshold detector circuit. An alarm device is triggered, when the preset threshold is reached as an indication of a reduced degree of wakefulness.

Abstract: Methods and materials for inducing anhydrobiosis in entomogenous nematode infective juveniles and then maintaining and storing them in an apparently anhydrobiotic state are described. Infective juveniles are induced into an anhydrobiotic state at relatively high relative humidity prior to optional lowering of the ambient relative humidity for storage and shipment. Suitable containers are also disclosed.

Abstract: Traps which include nematode infective juveniles as a toxic agent are effective in decreasing insect populations in a variety of environments. The traps of the invention contain a stable infective juvenile nematode population in a configuration which encourages nictation and the traps provide an effective harborage for the roaches or other insects. Relative humidity is maintained in the traps by the supply of molecular water.

Abstract: Infective juvenile nematodes can be stored for long periods of time when contained in a layer having pseudoplastic characteristics. The pseudoplastic layer immobilizes the infective juveniles, but the pseudoplastic nature of the compositions permits easy dispensing of the composition when required. Suitable pseudoplastic agents include rhamsan gum and xanthan gum.

Abstract: Entomogenous nematodes can be used as biological insecticides for the control of certain pests. The present invention provides a large-scale production in liquid culture of these entomogenous nematodes using an improved liquid culture medium. The medium uses an emulsifier to provide a well homogenized growth medium. The invention also provides a method of cultivating entomogenous nematodes on a commercial scale, in liquid culture, in fermenters by controlling the agitation rate as a function of oxygen demand.

Abstract: The present invention relates to an automatic device for analyzing successive samples which comprises a turning plate provided at its periphery with vertical sockets containing a small tube filled with the sample to be analyzed, a photomultiplier arranged opposite the lateral face of the plate comprising an orifice communicating with the sockets, a first flat seal adapted to be actuated by a ring to be brought into contact with the lateral face of the plate, a second flat seal adapted to be actuated by another ring above the socket and a third seal carried by a movable cradle below the socket.
