Abstract: A IRID object identification system equipped with active identifiers operation of which is based on transmission in the infrared radiation band is characterised in that the identification system uses IRID active identifiers operation of which is based on transmission in the infrared radiation band generated by narrow-angle infrared transmitters whereas a battery (3) of the energy management system (2) is recharged by solar cells (6), and the system comprises a device provided with transmitter (4) and receiver (5) equipped with reader (7). The device (1) of the system makes use directivity of emission in the infrared radiation band to analyse direction of motion of the identifier. This offers the possibility to handle more than one identifier present within the range of reader (7) and thus allows to overlap range areas of a plurality of readers (7) in the barrier or cellular (honeycomb) topology to increase precision of location of objects in a predefined area.

Abstract: The device for examination of the upper gastrointestinal tract equipped with a camera and connections system with the ability to connect a computer, video recorder, video printer and keyboard to describe the resulting image on the screen, characterized in that the device is in the form of a worm-like-shaped capsule equipped with the transparent dome with the camera (1) inside of the front part (2) of a shape similar to a part of a sphere passing smoothly into the flexural part (3) with possibility of extension and a rear part (4) with rounded edges.
