Abstract: An infusion-leakage detection device includes: a substrate; a circuit with an infusion-leakage detection region formed on the substrate and aligned to an IV catheter which is inserted into a blood vessel of a patient, and the region includes at least a light-emitting element emitting a light with wavelength within the second optical window of biological organization and at least a light detector receiving the light to generate an electrical signal; and a circuit and battery region formed on the substrate, including a control and calculation unit connecting to the light-emitting element, and an acceleration detector connecting to the control and calculation unit, sensing body movement of a patient and providing a body-movement signal to the control and calculation unit. A remote monitoring system including the infusion-leakage detection device and remote equipment which receive information of leakage/no-leakage and alarm signal to monitor infusion-leakage status remotely.

Abstract: A speech data retrieving and presenting device applied with an electronic device through a network includes a data receiving unit, a processing unit and a speech presenting unit. The data receiving unit connected to the network receives data of the electronic device through the network. The processing unit coupled to the data receiving unit receives speech data and retrieves a speech presenting signal from the speech data. The speech presenting unit coupled to the processing unit receives the speech presenting signal and outputs a speech according to the speech data. This device can assist a user to obtain network information, and provide the user a more flexible application according to the property that the device can be operated independently by a simple motion.
