Abstract: A measurement device includes a base, a platform, a temperature sensor, and a weighing component. The platform is movably disposed on the base. The temperature sensor is disposed on the base or the platform. The weighing component is accommodated in the base. The platform has a weight-measuring area and a temperature-measuring area which is located within the weight-measuring area and corresponding to the temperature sensor.

Abstract: A broadcast device, a broadcast system and an associated broadcast method are provided. The broadcast method includes the steps of: broadcasting a multimedia bitstream; detecting a first biological feature; updating contents of a database according to a broadcasting status of the multimedia bitstream when the first biological feature satisfies a first trigger condition; and broadcasting the multimedia bitstream according to the contents of the database when the first biological feature satisfies a first recovery condition.

Abstract: A DC motor comprising a rotor and a stator is provided. Wherein, one of the rotor and the stator in which the polarity of each magnetic pole is fixed is defined as a fixing magnetic pole unit, and the other one in which the polarity of each magnetic pole is varied is defined as a switching magnetic pole unit. The fixing magnetic pole unit comprises a plurality of fixing magnetic poles, and the switching magnetic pole unit also comprises a plurality of switching magnetic poles. The total number of the magnetic poles in the switching magnetic pole unit is K times of the total number of the magnetic poles in the fixing magnetic pole unit, where K is a positive integer greater than 1. The dc motor of the present invention can eliminate the starting dead angel and maintain a high torque.
