Abstract: An exercise system comprises a main body, at least one force-applied portion, a physiological information sensing device, a processing unit, and a transmission module. The at least one force-applied portion, on which a user can apply force, is connected to the main body. The physiological information sensing device comprises at least one flexible pressure sensing module and a heartbeat sensing unit. The at least one flexible pressure sensing module is connected to the at least one force-applied portion respectively. When the force applied by the user is input to the at least one force-applied portion, the at least one flexible pressure sensing module can produce pressure sensing information. The heartbeat sensing unit can measure heartbeat information. The processing unit is electrically connected to the physiological information sensing device. The processing unit manipulates the pressure sensing information and the heartbeat information and then produces output information.

Abstract: This invention relates to an optical switch with an arbitrary port number and its arrangement method for the optical communication system, and switches an optical path by using mirrors. The invention uses a network exchange algorithm to compute crossing points and reflecting points of the optical paths. Single-sided reflecting mirrors are disposed at the reflecting points of the optical path respectively, and double-sided reflecting mirrors are disposed at the crossing points of the optical path respectively. With the arrangement method, the arbitrary port number optical switch can be applied to satisfy the requirement for an arbitrary number of input and output terminals, so as to assure that an equal length of each optical path and to decrease the number of mirrors to minimize the cost, size and assembling time of the optical switch.
