Abstract: A diaphragm nasal breathing regulator includes a cylinder, a diaphragm, and an engaging unit. The cylinder has a channel, two openings opposite to each other along an axial direction of the cylinder, and a bearing surface allowing the diaphragm to be disposed thereon. The engaging unit engages the diaphragm to the cylinder. The diaphragm is formed with a through hole, and is movable relative to the bearing surface between an inhaling position and an exhaling position. When the diaphragm is in the exhaling position, the diaphragm rests on the bearing surface, and air can flow only through the two openings, the channel, and the through hole. When the diaphragm is in the inhaling position, the diaphragm is away from the bearing surface in the axial direction, and air can flow through the two openings, the channel, the through hole, and a gap between the cylinder and the diaphragm.

A first electronic device generates first signature information according to the first signature request. A second electronic device generates second signature information according to the second signature request. The signature server generates a first credential request and a second credential request according to the first signature information and the second signature information. The credential server transmits a first credential object and a second credential object to the signature server in response to the first credential request and the second credential request.

The method includes: obtaining the face of a person in the first image, as well as the result of facial recognition; determining whether the distance between the person and the target is within an effective attention range; determining whether the face is frontal; determining whether the effective attention period is not shorter than a period threshold; detecting the focus of attention for the person to the target.

Abstract: An online signing system and method, a computing apparatus, and a computer-readable recording medium are provided. An assigned task is generated by a task assignment apparatus to the computing apparatus. The computing apparatus generates a signing request based on the assigned task to be transmitted to a client apparatus. The client apparatus downloads an assignment file from a storage database based on the signing request to display the assignment file on a display. The client apparatus receives an input via an input unit to generate a signature object on the assignment file, and transmits the signature object to the computing apparatus. After receiving the signature object, the computing apparatus combines the signature object and the assignment file to obtain a signed file, and transmits the signed file to the storage database.

Abstract: Apparatus and methods are disclosed for power optimization in a wireless device. The apparatus and methods effect monitoring the amount of data stored in a data buffer that buffers data input to and data output from a processor. Dependent on the amount of data stored in the buffers parameters of a control function, such as a Dynamic Clock and Voltage Scaling (DCVS) function are modified based on the amount of data stored in the data buffer. By modifying or pre-empting the parameters of the control function, which controls at least processor frequency, the processor can process applications more dynamically over default parameter settings, especially in situations where one or more real-time activities having strict time constraints for completion are being handled by the processor as evinced by increased buffer depth. As a result, power usage is further optimized as the control function is more responsive to processing conditions.
