Abstract: In various embodiments, the present disclosure provides a layered metal-air cathode for a metal-air battery. Generally, the layered metal-air cathode comprises an active catalyst layer, a transition layer bonded to the active catalyst layer, and a backing layer bonded to the transition layer such that the transition layer is disposed between the active catalyst layer and the backing layer.

Abstract: The present invention discloses a method and a device for sending a radio link layer status package, and the sending method comprises: when the universal terrestrial radio access network detects that there is data to be sent which has been sent but has not been acknowledged, if a response from a receiving side is not received after a radio link layer status package is sent to the receiving side, a reset operation of the radio link layer is executed. The present invention resets the radio link control layer in time when the path between the universal terrestrial radio access network and the receiving side is failed or invalid, therefore it is advantageous to maintain the stability and self-recovery of system.

Abstract: A computer system consists of a plurality of electronic elements and a switch control circuit. The switch control circuit controls the computer system to enter a stand-by/power off state from a normal state when the computer system receives a stand-by/power off command under the normal state, and stops outputting a stand-by power having at least one stand-by voltage level to at least one part of electronic elements among the plurality of electronic elements. At this time, the computer system has entered a simulated mechanical off state from the stand-by/power off state. A number of electronic elements supplied by the stand-by power when the computer system lies under the simulated mechanical off state is smaller than a number of electronic elements supplied by the stand-by power when the computer system lies under the stand-by/power off state.

Abstract: A controlling circuit for controlling an operating clock of a logic circuit in an electronic device and the method thereof are disclosed. The controlling circuit includes a storage device, a detector, at least one comparator, and a controller. The storage device stores a first threshold value and a first return value. The detector detects a system load of the electronic device to generate a detection value. The comparator compares the detection value with the first threshold value or the first return value. When the detection value decreases to reach the first threshold value, the comparator generates a first indication signal. When the detection value increase to reach the first return value, the comparator generates a second indication signal. The controller enables underclocking of the logic circuit when receiving the first indication signal, and disables underclocking of the logic circuit when receiving the second indication signal.

Abstract: A brake drum that converts kinetic and potential energy into frictional heat without developing destructively high temperatures and provides such performance at a reduced weight with an increase in cooling effectiveness through the use of a squealer band positioned on the centerline of the drum braking surface along with axial cooling fins radiating therefrom and windows on the wraparound portion abutting mounting face.

Abstract: A novel brake drum includes one or more mid-positioned squealer bands that are roughly in line with the ribs of the brake shoes. This places the most rigid part of the brake drum and the location of greatest heat sink over the most rigid portion of the brake shoes, which is also the position of greatest heat input. The axial cooling fins radiating from the squealer band aid in dissipating the heat from friction generated during the braking cycle.
