Abstract: The invention relates to a closed loop system which is used in modulating gastric activity. By appropriate deployment of the components of the system, one can monitor and modulate “slow waves” in the gastrointestinal system of a subject.

Abstract: A method of defining a model of one or more organs or part(s) thereof from multiple images of the organ(s) or part(s) thereof, the method comprising the steps of generating a computational mesh of one or more organs or part(s) thereof from multiple images of the organ(s), or part(s) thereof; generating a representation of musculature or part(s) thereof associated with the organ(s); calculating electric and/or magnetic fields associated with the muscle layers; and defining a model based on the computational mesh, and the electric and/or magnetic fields.

Abstract: A digital display instrument with an automatic power-off device built-in which comprises a control circuit, a timing circuit and a display detection circuit. The power of the instrument is controlled by a push-button switch so that when the push-button switch is pressed down and released immediately, the power is turned on. If the push-button switch is pressed down and held for about 1.5 seconds, however, the power is turned off. The power can be turned off automatically by detecting if the instrument has not been used for a pre-set period of time. After the power is turned on, the display detection circuit will monitor the reading on the display continuously to determine whether the instrument is in use or not. If the detection shows the instrument is still in use, the timer will be reset to maintain the power on for another period of time. However, if a condition of not being in use is detected within the preset period of time, the power will be turned off automatically.
