Abstract: A wearable bio-electromagnetic sensor comprises an electronic unit containing a means for generating electrical current, and an electromagnetic interface for transforming the generated electrical current into an electromagnetic field applied to a vascularized body tissue. Next, the wearable bio-electromagnetic sensor contains a means for analog signal processing an electrical response of cardiopulmonary system to the applied electromagnetic field. After analog processing of said electrical response, a digital post-processing of digitized electrical response takes place in a means for digital signal processing, embedded into said electronic unit of the wearable bio-electromagnetic sensor. As a result of analog and digital signal processing, an information is extracted, which makes possible medical diagnosing of both, pulmonary and cardiovascular system, separately or simultaneously.

Abstract: The invention is related to the field of measurement electronics and related to the measurement of complex transfer functions (e.g. of impedance), especially in the presence of large disturbances and for measuring of small changes of the characteristics of the object under test. The goals of the proposed invention are achieved by detuning of the excitation and reference signals, e.g. by adding incremental phase-shift to the excitation signal to generate the reference signal.

Abstract: A phone holder for a mobile phone testing apparatus which comprises at least a base plate, a rest structure on the base plate for supporting a mobile phone, at least one block for contacting a mobile phone's narrow side, wherein the at least one block is moveably attached to the base plate, thereby enabling adapting the position of the block to a mobile phone being supported by said rest, and clamping means for releasable fixing the at least one first block in said position can be configured for securely holding almost any mobile phone model.
