Abstract: Example embodiments relate to a system for monitoring biosignals and also to a patch and an apparatus which may include part of the system. The system may include a patch including a surface for attachment to a user, first sensors for sensing respective first biosignals of the user, and a transmitter for wirelessly transmitting first biosignal data representing the first biosignals of the user. The system may also include an apparatus for being worn or placed over the patch, the apparatus including second sensors at or near a lower surface thereof for sensing respective second biosignals of the user and providing second biosignal data representing the second biosignals. The apparatus may also include a receiver for wirelessly receiving the first biosignal data from the patch. The patch may include recesses or apertures for alignment with the second sensors when the apparatus is worn or placed over the patch.

Abstract: A portable electronic device is provided which includes a first housing; a second housing that is coupled to the first housing; at least one pair of antenna elements that are housed in the first housing; and a switch element that connects the antenna elements to a transmission/reception circuit module. The switch element connects a first antenna element to the transmission/reception circuit module when the first and second housings are folded and connects a second antenna element to the transmission/reception circuit module when the second housing is unfolded.
