Abstract: An ambulatory intrinsic brain signal processor circuit is coupled to a plurality of electrodes. The signal processor circuit can include a digital multiplexer circuit coupled to the electrodes to multiplex brain signal data from different electrodes together into a multiplexed data stream. An ambulatory transceiver circuit wirelessly communicates information to and from a remote transceiver. A controller circuit permits a user to control which of the electrodes contribute data, a data resolution, and whether the data includes one or both of neural action or local field potential data. Seizure prediction components and methods are also described.

Abstract: Bioelectrical activity in a living animal or human subject is monitored by detecting the bioelectrical signals at a number of points digitizing and multiplexing the electrical signals and transmitting the multiplexed stream by digital radio transmission circuitry. The received data stream is then demultiplexed and monitored to allow the activity at the points on the animal subject to be monitored.

Abstract: Bioelectrical activity in a living animal subject is monitored by detecting the bioelectrical signals at a number of points multiplexing the electrical signals and transmitting a multiplexed stream by cellular telephone circuitry. The received data stream is then demultiplexed and monitored to allow the activity at the points on the animal subject to be monitored.

Abstract: In order to ensure the recovery and confinement of the core of a nuclear reactor, such as a pressurized water reactor, in the case of a serious accident leading to its melting or meltdown, it is proposed that below the reactor vessel (16) be placed a receptacle (20) able to evacuate the water accumulated below the vessel (16) in the initial phase of the accident and then collect the molten core debris. The water automatically flows through overflow and siphon devices (46, 50) into a cooling space (40) located below the receptacle. If the meltdown of the core (18) has been detected, the water contained in tanks (56) flows by gravity into the space (40), so as to entirely immerse the containers (26) placed in said space. The molten core traversing the bottom of the vessel (16) flows into the receptacle (20) and then into containers (26) via meltable plugs (32) and a natural convection flow is established between the tanks (56) and the space (40) in order to ensure cooling.

Abstract: A method for the determination of the heat transfer coefficient on a heat transferring surface, including the steps of arranging a layer for measuring the surface temperature and heat flux on the heat transferring surface so that the layer can change the original temperature and heat flux to a negligible extent only, providing for the slight and properly slow changeability of the surface heat flux density within a cycle time which is by several orders of magnitude longer than the time constants of the heat flux measuring layer and of the heat transferring boundary layer, by using a supplementary heating element and performing a practically unlimited number of measuring cycles, using the steps of deflecting the surface heat flux density and temperature relative to the condition in which no measurement takes place. The time-functions of the changes of the surface temperature .DELTA.T and of the surface heat flux density .DELTA.

Abstract: The invention is, on the one hand, a method for drying products, especially corn or articles, in the course of which the products to be dried are traversed by a drying gas, the moisture content of the drying gas is diminished by contacting it with a desiccant liquid, and the desiccant liquid is at least partly regenerated after the contact. According to the invention, the drying gas stream flows through at least two layers of products to be dried successively, and before or after flowing through each layer of products it is brought into contact with the desiccant liquid.

Abstract: An agricultural cutter has in its drive train a pulley for a V-belt. Between the rim of the pulley and the spokes thereof, coil compression springs are provided, so that upon the imposition of high power demand during cutting of an agricultural product, power will be momentarily stored in the spring and then released in connection with the cutting operation.
