Abstract: A card having a fingerprint sensor and a manufacturing method of the same are provided. The fingerprint sensor is disposed between a substrate and a protection layer. The protection layer has a first area and a second area thereon. The roughness of the second area is smaller than the roughness of the first area. The second area corresponds to the sensing area of the fingerprint sensor. When the user's finger is wet, the second area may effectively keep the water from remaining on it. Thus, the water does not affect the effect of fingerprint sensing.

Abstract: A smart card with a fingerprint sensing system, includes a controller and a fingerprint sensing device. When the fingerprint sensing device senses a fingerprint to generate a fingerprint frame data, the controller enters a sleep mode, and when the controller reads the fingerprint frame data, the fingerprint sensing device stops sensing the fingerprint. Since operations of sensing the fingerprint and reading the fingerprint frame data do not occur at the same time, the high current condition can be avoided so as to decrease power consumption.

Abstract: A smart card has a light-emitting element, a fingerprint sensor and a microcontroller. An operation of the smart card has a plurality of indication periods to indicate operation statuses of the smart card by the light-emitting element. The control method of the smart card includes generating a light source control signal, controlling a current supplied to the light-emitting element by the microcontroller according to the light source control signal, and decreasing the current supplied to the light-emitting element or stop the current supplied to the light-emitting element during at least one power-saying period in a first indication period of the plurality of indication periods.

Abstract: A smart card includes a microprocessor, a biometric sensor, a power supply decision unit, and a power detection unit. When the power source provides electric power to the smart card, the microprocessor of the smart card operates at a lower operating frequency initially. After determining by the power supply detecting unit and the power supply decision unit, it is determined whether a power source provides a higher current or voltage. The microprocessor further determines whether to adjust the operating frequency according to the determination. If so, the operating frequency is further increased to speed up the processing and thereby enhance the user experience.

Abstract: A cursor control device has a touch control module for users to perform a swipe gesture. The touch control module generates a control command according to the swipe gesture and transmits the control command to a host computer. The host computer then launches a swipe menu on an edge of a display screen thereof Accordingly, after a host computer with the Win8™ installed therein as the operating system receives the control command, the edge swipe function supported by the Win8™ can be launched.

Abstract: An apparatus and process are disclosed for automatically changing the speed of a recording tape from a first speed to a second speed, based on a one-time determination of predicted time of changeover. The second speed is 1/n of the first speed, where n is any real number greater than 1. A central processing unit determines the time of changeover at the start of the recording process, using inputs from a recording timer and a reel detector to determine the program time and the remaining tape time on a supply reel. When the program time initially exceeds the remaining tape time at the first speed, the system automatically predicts and then implements the changeover to the second speed, such that the first speed portion is maximized to take advantage of its superior signal-to-noise ratio.
