Abstract: The respiratory exercise device comprises means for detecting the respiration of a person and it is characterized in that said means for detecting the respiration of a person comprises a turbine whistle (3) which generates a variable frequency sound as a function of the air flow which passes through the same and a microphone (4) which captures said variable frequency sound generated by the turbine whistle (3). The method for respiratory exercise comprises the steps of obtaining data relating to the respiration of a person with the previous device, sending said data relating to the respiration to control means; and applying an algorithm to said data for calculating the values of the flows generated by the respiration. It allows respiratory exercise to be carried out in a simple manner, even for children.

Abstract: An improved electrical contact according to the invention has a U-shaped base having a bottom and two opposing side walls that define a tab-receiving channel. The base has an open forward end for receiving a mating tab terminal and a rearward end with a middle region therebetween. A contact spring is disposed over the bottom and has a bridge which spans the bottom between the opposing side walls in the middle region of the base. A first contact arm extends from the bridge towards the forward end and converges towards the bottom to a first contact point and then diverges to a free end thereby defining a mating tab insertion mouth. A second contact arm extends from the bridge towards the rearward end and converges towards the base to a second contact point that is disposed closer to the base than the first contact point. The bridge is continuous with one of the opposing side walls and includes a free end that is attached to the other opposing side wall.
