Abstract: An artificial gravity heating system includes a cylindrical compartment formed of a hollow cylinder having a bottom base and an open top end. An electric motor rotates the cylindrical compartment to provide centripetal motion of materials inside the cylindrical compartment. While rotating, the materials move towards an inner wall of the cylindrical compartment. A heating element is conductively coupled along an outer wall of the cylindrical compartment for heating the materials against the inner wall via conduction. A temperature sensor is operatively coupled to the cylindrical compartment for monitoring a temperature of the cylindrical compartment. A controller is configured to control operation of the heating element based on the temperature monitored via the temperature sensor. An artificial gravity heating method is used to process materials including heating ingredients to cook food. The artificial gravity heating system may also be configured as a vapor generator dehydrator or a thermal gas generator.

Abstract: The invention relates to measuring and generating electrical fields downhole. In one embodiment a system is provided that includes an amplifier connected to a first electrode in electrical contact with the Earth via an operative capacitive coupling. An additional electrode and amplifier are disposed in the borehole opposite the first electrode and constitute a first pair of electrodes spaced in a direction orthogonal to the axis. A second electrode is part of a group of counter electrodes spaced from each other and disposed outside the borehole. The first pair of electrodes and the amplifiers are configured to be one of a source that generates an electrical field in a direction substantially orthogonal to the axis of the borehole and a sensor that measures an electric field substantially orthogonal to the axis of the borehole.

Abstract: The invention relates to measuring and generating electrical fields downhole. In one embodiment a system is provided that includes a first electrical conductor within a borehole and in electrical contact with the Earth. An amplifier is connected to the first electrical conductor and a second conductor completes an electrical circuit between the conductors such that the electrical field is oriented in a direction substantially orthogonal to the axis of the borehole.

Abstract: A capacitive sensing system (2, 2?, 2?) is used to measure a timevarying ion current through a channel (50), such as an ion channel or protein pore. Such a capacitive system (2, 2?, 2?) does not suffer problems of electrode corrosion and, when used with methods to control a build up of ion concentration, allows the use of measurement volumes (10, 20) around the channel (50) with dimensions on a scale of nanometers.

Abstract: A compact sensor system integrates electric and/or magnetic field sensors to accurately measure, with a high level of sensitivity, one or more electric and magnetic vector components of fields. The electric and magnetic field data can be utilized separately or combined. The sensor system is self-contained so as to include a built-in power source, as well as data storage and/or transmission capability. The integrated sensor system also preferably includes a global positioning system (GPS) to provide timing and position information, a sensor unit which can determine the orientation and tilt of the sensor system, and self-calibrating structure which produces local electric and/or magnetic fields used to calibrate the sensor system following deployment.

Abstract: An integrated fluxgate-induction sensor is formed of a combined fluxgate sensor and induction sensor using a common core. The sensor may be in serial operation where it switches between a fluxgate mode for measuring static magnetic fields and an induction mode for measuring alternating magnetic fields. Additionally, the sensor may be used in an interleaved operation where the sensor operates from the fluxgate mode during the transition period where its core is changing from a high permeability state to a low permeability state or vice versa, while the sensor operates in the induction mode when the core is in its high permeability state. The resulting sensor provides for a compact magnetic sensor system capable of sensing magnetic fields which oscillate from zero frequency to 10 kHz and higher.

Abstract: A system and method for non-invasively measuring the electrical potential radiated by a cell. To do this, a probe is positioned within ten microns distance from the cell for receiving the signal. Also, a reference potential is determined for the cell's environment. A sensor records the signal and compares the reference potential to the cell's signal to measure the electrical potential of the cell.

Abstract: A sensor system accurately measures, with a high level of sensitivity, one or more vector components of a small electric field, through the use of multiple, relatively fixed sensors, at least one of which constitutes a weakly coupled capacitive sensor. The sensor system enables the electric field to be determined in a direction normal to a surface or along multiple orthogonal axes. Measurement of the electric field vector can provide improved resolution and characterization of electrical signals produced, for example, by organs within the human body.
