摘要:A posture training device includes in a mechanical-electrical embodimentthereof, an electrically conductive plate divided into two contact zones and slidable upona support base of one housing section of the device. One end of the plate is operativelyconnected to a body harness cable extending around the longitudinal axis of the bodyfrom the pubis to the scapula, while the other end of the plate is electrically connectedto spring-biased cable winding mechanisms. The two zones of the plate are separatedand electrically insulated from each other by a predetermined gap which extends alongthe plate with a predetermined curvature or rectilinearly at a constant slope, and anotherslidable plate, having a contact member disposed therein, is similarly provided withinanother housing section with a harness cable at one end thereof, which cable extendslaterally about the chest area of the patient, and is operatively, electrically connected toa spring-biased cable winding mechanism at the other end thereof through means of thecontact member. The electricaly conductive plate and contact member of the secondplate serve as a single-pole, double-throw switch and common contact memberrespectively, and the relative movement of both plates, as defined by the contactmember and the zones of the electrically conductive plate, serve to open or close asignal emitting circuit so as to accurately indicate the assumption of a proper or improper
postural position or condition by the patient, independent of the respiration of thepatient.
< P>In another, electronic embodiment of the invention, in lieu of the sliding plates ofthe aforenoted embodiment, rotary potentiometers are utilized, the generated voltagesof which serve to indicate the length or lengthening, or movement, of the cables securedthereto in a manner similar to the securing of the same to the sliding plates, and throughmeans of a trim resistor, which serves a similar function as that of the sloped gap of thezoned plate, the voltages are differentially and then comparatively amplified andsupplied to the signal emitting circuit.
