  • Patent number: 10799120
    Abstract: An image processing method for a fluorescence reaction region of teeth. The image processing method includes emitting blue light from a light source to illuminate the teeth in a mouth, so that the teeth generate fluorescence; capturing a first teeth image of the teeth by an image capturing unit; separating the first teeth image into a first red-value image, a first green-value image, and a first blue-value image by a processing unit; transforming the first red-value image into a second red-value image by the processing unit using a pixel value transforming function; and combining the second red-value image, the first green-value image, and the first blue-value image into a second teeth image by the processing unit.

  • Publication number: 20190310714
    Abstract: A motion evaluation system, a method thereof and a computer-readable recording medium are provided. The motion evaluation system includes at least one sensor and a processor. The sensor generates sensing data for a motion posture. The processor obtains the motion posture of the sensor, determines a continued time accumulated when the motion posture conforms to a correct posture, and sends a notification message according to the continued time. The correct posture is related to an angle at which a portion under test inclined to a reference object. Accordingly, the rehabilitation can be performed anytime and anywhere, and it is easier for tracking the rehabilitation situation.

  • Patent number: 9888363
    Abstract: A method in one example embodiment includes identifying a power state and a battery level of a vehicle. The method also includes allocating power to critical applications (for example) in response to determining that the battery level is above a reserve threshold while the power state of the vehicle is engine-off. The method also includes allocating remaining power in excess of the reserve threshold to non-critical applications according to a power management policy. The power management policy may comprise at least one of a user power preference index and an application power preference index.

  • Patent number: 8913188
    Abstract: In one embodiment, a method is provided that includes receiving a transmitted combined video and closed caption (CC) signal. The combined signal is separated into a CC signal and a video signal. The CC signal is converted into an original CC text stream. The method also includes translating the original CC text stream from a first language into a second language to from a translated CC text stream. In more specific embodiments, the method includes inserting each translated CC text stream into the video signal. The translated CC text can appear instead of the original CC text when the video signal is displayed.
