  • Publication number: 20240136864
    Abstract: A wireless power transmission device includes a transmission device and a control device. The control device generates a driving signal to the transmission device in a first soft-start period, so as to drive the transmission device. The control device measures an energy message generated by the transmission device to generate a measurement result in a measurement period, and calculates a signal parameter according to the measurement result. The control device accordingly generates a carrier signal according to the signal parameter obtained by the measurement period in a second soft-start period. In a transmission period, the carrier signal is transmitted to the wireless power-receiving device through the transmission device. The energy message is generated by the transmission device in response to a distance between the transmission device and the wireless power-receiving device.

  • Patent number: 9116135
    Abstract: A surface pattern detecting method includes: capturing a surface image of a sample element to be detected, wherein the surface image containing N grayscale pixels and wherein the N is a positive integer; selecting f×N pixels with small grayscale value based on a selection ratio f in order to define a pattern zone and further calculating a pattern mean of the pattern zone based on pixel amount and grayscale value of the pattern zone; selecting f×N pixels with big grayscale value in order to define a background zone and further calculating a background mean of the background zone based on pixel amount and grayscale value of the background zone; and determining whether the surface image has a defect based on the pattern means of the pattern zone and the background mean of the background zone.

  • Patent number: 7193697
    Abstract: An apparatus for feature detection of a test object includes at least one light source module and at least one image capturing unit. The light source module provides light to illuminate a test region of the test object, and includes a substrate, a set of light-emitting components, and a light-focusing unit. The light-emitting components are mounted on the substrate for emitting light in parallel directions that are generally transverse to the substrate. The light-focusing unit is to be disposed between the light-emitting components and the test object, receives the light emitted by the light-emitting components, and focuses the light on the test region of the test object. The image capturing unit captures an image of the test object at the test region.
