A detecting apparatus includes a housing support section(s), a housing removably
attached thereto, one or more sensors and a processor. An alternate apparatus measures
heat flux and includes a known resistivity base member, a processing unit and two
temperature measuring devices, one in thermal communication with the body through
a thermal energy communicator and the other in thermal communication with the ambient
environment. A further alternate apparatus includes a housing or flexible section
having an adhesive material on a surface thereof for removably attaching the apparatus
to the body. A further alternate apparatus includes a housing having an inner surface
having a concave shape in a first direction and convex shape in a second direction
substantially perpendicular thereto. Also, an apparatus for detecting heart related
parameters includes one or more filtering sensors for generating filtering signals
related to the non-heart related motion of the body.
