Abstract: A centrifugal heat dissipation fan of a portable electronic device. The centrifugal heat dissipation fan includes a hub, multiple metal blades, and at least one ring. The metal blades are disposed surrounding the hub. The metal blades include multiple radial dimensions, and the structure of the metal blade with a shorter radial dimension is a part of the structure of the metal blade with a longer radial dimension. The metal blades having different radial dimensions form at least two ring areas, and the distribution numbers of the metal blades in the at least two ring areas are different from each other. The ring surrounds the hub and connects the metal blades.

Abstract: A centrifugal heat dissipation fan including a housing and an impeller is provided. The housing has at least one inlet disposed along an axis and at least one first outlet and a second outlet located in different radial directions, wherein the first outlet and the second outlet are opposite to and separated from each other. The impeller is disposed in the housing along the axis. A heat dissipation system of an electronic device is also provided.

Abstract: A blood pressure device includes a first blood pressure measuring device, a second blood pressure measuring device, and a controller. The first blood pressure measuring device is to be worn on a first position of a wrist so as to obtain a first blood pressure information of the first position. The second blood pressure measuring device is to be worn on a second position of the wrist so as to obtain a second blood pressure information of the second position. The controller is electrically coupled to the first blood pressure measuring device and the second blood pressure measuring device so as to adjust tightness between the expanders and the user's skin, respectively. The controller receives, processes, and calculates a pulse transit time between the first blood pressure information and the second blood pressure information, and the controller obtains at least one blood pressure value based on the pulse transit time.

Abstract: A centrifugal heat dissipation fan including a housing and an impeller disposed in the housing on an axis is provided. The housing has at least one inlet on the axis and has a plurality of outlets in different radial directions. A heat dissipation system of an electronic device is also provided.
