Abstract: The invention relates to an in vivo sensing device having a specific gravity of about 1 or a volume to weight ratio that enables it essentially to float. In one embodiment the in vivo sensing device consists of an image sensor system and a buoyant body. The buoyant body, which is attached to the sensor system or which can optionally house one or more elements of the sensor system, keeps the sensor system essentially floating in a body lumen liquid.

Abstract: A 3D camera for determining distances to regions in a scene comprising: a photosurface having a plurality of pixels each of which comprises a circuit having a light sensitive element that provides a current responsive to light incident thereon, wherein the circuit comprises, at least one amplifier inside the pixel, having an input and an output; at least one feedback capacitor separate from the light sensitive element and connected between the input and output of each of the at least one amplifier; at least one controllable connection through which current flows from the light sensitive element into the input of the at least one amplifier; a light source; and, a controller that, controls the light source to illuminate the scene with light, opens and closes the at least one controllable connection to gate or modulate current from the light sensitive element of a pixel in the photosurface responsive to the time dependence of the gating or modulation of the light, controls the at least one controllable connectio

Abstract: An implantable heart defibrillator for use with an electrode lead system is provided. The implantable heart defibrillator includes an electrode lead connector that is connectable to the electrode lead system. A sensor is operable to sense a condition of a heart and emit a condition signal that identifies the condition. A control unit is operable to identify whether a state of fibrillation exists from the condition signal and emit a command signal if the state of fibrillation exists. A shock pulse generator is operable to emit at least one defibrillation shock to the electrode lead connector upon receipt of the command signal. The at least one defibrillation shock comprises at least one pulse having a voltage of more than 600 volts and a time duration of 30 to 100 microseconds.
