Abstract:
A fan wheel comprises an axial line, a radial line perpendicular to the axial line, a first vane and a second vane, and the first vane and the second vane are extended from the axial line, and included angles between chord lines of the first and second vanes and the axial line of the fan wheel are unequal angles. A heat dissipating fan comprises a fan hub, a plurality of first vanes and a plurality of second vanes, and the first vanes and the second vanes are extended outwardly from the fan hub, and excluded angles between their chord lines and the axial line of the fan hub are unequal angles.
Abstract:
A fixing device is applied to fix a breathing tube which includes a free segment located outside a patient, and the fixing device contains: an adjustable collar, a connector, and a fixer. The adjustable collar surrounds a limb of the patient, and the adjustable collar includes a first part and a second part opposite to the first part. The connector connects with the adjustable collar, wherein the first part and the second part of the adjustable collar respectively insert through the connector. The fixer includes a base mounted on the connector and includes two arms extending outwardly from the base so that the free segment of the breathing tube is clamped by the two arms.
Abstract:
The present invention discloses a Universal Serial Bus (“USB”) device that includes an Ethernet port configured to receive a first Ethernet packet, and an input control circuit including a data register memory, a header register memory and an input data control circuit. The input data control circuit, upon receiving a first Ethernet packet, stores first packet data of the first Ethernet packet in the data register memory, transmits the first packet data to a USB host, and, in response to the transmission of the first packet data, stores first header data of the first Ethernet packet in the header register memory.
