Abstract: A neural network computing chip and a neural network computing method are provided. The computing chip includes a translation circuit and a computing circuit. After input data is processed by the translation circuit, a value of each element of the data input into the computing circuit is not a negative number, thereby meeting a value limitation condition imposed by the computing circuit on the input data. Therefore, a calculation result can be obtained by performing calculation for only one time, and there is no need to perform calculation for two times. Therefore, neural network computing efficiency is improved, and a delay of a neural network operation is reduced.

Abstract: The present invention generally relates to a fan and in some aspects to an impeller with increased performance or efficiency. The fan according to some embodiments of the present invention has a housing, an impeller, and a motor driving the impeller. The impeller can be manufactured and/or arranged within the housing to make the fan more efficient under certain operating conditions. In some embodiments, the impeller is equipped with blades having a non-constant radius of curvature. In other embodiments, the impeller is equipped with two sets of blades, which include primary blades and secondary blades. These blades can be offset from each other to increase performance. In yet other embodiments, the space between the secondary blades and the housing can be manipulated to increase performance. Additionally, other embodiments adjust the cross-sectional shape of the flow path through the impeller to increase performance.

Any one or more of these parameters can be utilized alone or in combination with other parameters as desired.

Abstract: The present invention employs improved fan blade shapes to improve fan blade performance in one or more manners (i.e., increased fan efficiency, lower fan noise, greater fluid moving capability, and the like). In some embodiments, the fan blade has a front side, a rear side, an inner attachment portion, an outer edge, a curved leading edge and a curved trailing edge. The outer edge can define an arc between a forward position and a rearward position of the fan blade. In some embodiments, the leading edge extends outward and intercepts the arc of the outer edge at the forward position, and the trailing edge extends outward to the rearward position. Various angles, lengths, and other dimensions of the blade can have selected values to produce superior fan performance.
