The present invention relates to a micro-robot control apparatus. An electromagnetic module for focusing magnetic field and a micro-robot control apparatus comprising the electromagnetic module, according to the present invention, focus the magnetic field in an area of interest where focusing of same is desired to allow a micro-robot to be controlled, and, the apparatus having been simplified, allow efficient setup and operation in the surgery area. Moreover, the number of electromagnets is reduced to thus reduce the number of sources of power, thereby resulting in efficient operation of the apparatus with lowered power consumption. Additionally, by means of a magnetic induction frequency signal reception coil of the micro-robot and the external micro-robot control apparatus equipped with a magnetic induction transmission coil, the micro-robot control apparatus can both generate power wirelessly for the micro-robot, and implementation location recognition of same due to the efficiency of the generated power.

Introduced here is an ingestible device comprising a capsule having a central axis therethrough, at least one propulsion component, and at least one motor configured to supply motive power to the propulsion component(s). The propulsion component(s) may be disposed at locations radially offset from the central axis. Upon receiving input indicative of a request to alter a position and/or an orientation of the ingestible device, the motor(s) can supply motive power to some or all of the propulsion component(s) to cause movement of the ingestible device.

A power source apparatus and a system incorporating said power source for medical capsules are disclosed. A medical capsule often includes a power source sealed in a housing. Embodiments of the present invention allow the medical capsule to enable/disable electrical power supplied to a sub-system in the capsule device without special tools and/or skills after the medical capsule is manufactured. In one embodiment, the power source apparatus comprises a plunger responsive to a magnetic field, a spring to interact with the plunger, a battery and a control piece. The plunger is moved between first and second positions according to a magnetic field applied externally. Accordingly, the control piece enables or disables the power depending on the plunger positions. In another embodiment, a capsule system uses an electrical interconnect with pressure contacts between the power source and the capsule sub-system connecting the second circuit board to the power-output nodes.

The invention relates to an optical measuring method for three-dimensionally capturing the surface of an object by means of an optical capturing unit, wherein the optical capturing unit is moved relative to the object during a first measurement time period, the object is illuminated by the capturing unit with an illumination beam having a light intensity, height images are captured by the capturing unit in succession at a capturing frequency, at least some of the captured height images during the measurement tune period are added to form a total height image and the total height image is displayed, and the light intensity and/or the capturing frequency are controlled during the measurement time period by control signals, the control signals being produced at time intervals during the measurement time period and each control signal being produced on the basis of at least one sensor signal of a temperature sensor.

The present invention is directed to locating and imaging with a swallowable sensor device disposed in a patient. The swallowable sensor device transmits an acoustic signal from inside a patient's body. A plurality of sensing elements receive the acoustic signal. A computation module determines a location of the swallowable sensor device with respect to the plurality of sensing elements based on the acoustic signal received by at least a subset of the plurality of sensing elements. A three-dimensional image of an interior portion of the patient can also be formed based on the received acoustic signal. The three-dimensional image may be formed by stereoscopically displaying two two-dimensional images of the interior portion, wherein the two two-dimensional images correspond to the swallowable sensor device being located at two different locations. Alternatively, the three-dimensional image may be formed by computing three-dimensional pixels of the interior portion.

Computerized information acquisition and processing apparatus. In one embodiment, the apparatus includes a video apparatus with image capture and digitization capability, and multiple wireless interfaces for accomplishing various purposes, including e.g., streaming the digitized video data to another device for viewing and/or storage thereon. In one variant, one of the wireless interfaces is a short range passive RFID-based interface which generates replies to interrogation signals, the replies including user-specific information.
