Abstract: Apparatus and method can be provided for obtaining at least one anatomical sample. For example, it is possible to provide and insert a housing into a body or provided on a hydrated anatomical structure. Further, with a source, it is possible to emit an electromagnetic radiation which causes at least the anatomical sample(s) to attach to at least one portion of the housing. A compound can be provided on a surface of the housing, and the source provides the radiation to the compound and changes properties thereof to be adhesive. The source can provide the radiation to the housing, and can change properties of a surface thereof to be adhesive. A component can be provided on a surface of the anatomical structure, and the source provides the radiation to the compound and changes properties thereof to be adhesive.

Abstract: A rotary position encoder includes a detection unit and a scale co-configured and co-operative to detect a relative rotational position and to generate a position output accordingly. The scale has a scale pattern according to a linear-feedback shift register (LFSR) pseudo-random code, which is a non-maximal length code having a seed value, tap positions, and modified least-significant bit position(s) of code words that satisfy rotary constraint by which each code word follows in sequence from the adjacent code word.

Abstract: A motion sensor applicable to medical procedures includes a source of light with a wavelength bandwidth and an optical detector. A first optical coupler terminates in a first probe tip and couples the light into the first probe tip. A second optical coupler terminates in a second probe tip and directs onto the detector scattered light returning through the second probe tip. A presentation device outputs a signal that indicates motion in a target volume of a sample in a vicinity of the probe tips based on a Doppler shift of the scattered light. The volume depends on coherence distance determined by the bandwidth. In variations, the first and second tips are the same tip, a multimode fiber is included, the bandwidth is between 0.1% and 5% of a center wavelength, or the presentation device is a speaker, or some combination.
