  • Patent number: 10702139
    Abstract: A laryngoscope with a rotatable and turnable display is revealed. The laryngoscope includes a laryngoscope body, a rotating assembly, a turnover assembly and a display. The laryngoscope body is used to capture images. The rotating assembly is disposed over the laryngoscope body and having a plurality of elastic bodies or first and second magnetic parts used in combination with a slot of a first fixed shaft. Thus the display is rotated around the rotating assembly and a rotation angle of the display is determined according to the position of the slot. The turnover assembly is arranged at one side of the display. The display is flipped around the turnover assembly by a fixing member of a second fixed shaft being mounted into at least one fixing hole of a turnover portion. The angle of the display being turned is determined according to the position of the fixing hole.

  • Patent number: 9989415
    Abstract: A method for creating a uniformity compensation look-up table is revealed. The method includes the following steps. First measure a plurality of areas on a plane users intend to make uniform to get a measured value of the respective area. Then get a central uniform estimate of a center of the plane. Also get a linear skeleton according to the position of one of the measured values and the position of the central uniform estimate. Next get a plurality of skeletal uniform estimates on the linear skeletons respectively by interpolation or extrapolation of the measured values, the central uniform estimate, and the distance between the position of the measured values and the center of the plane. At last get a plurality of planar uniform estimates on the plane in turn according to the skeletal uniform estimates of the two adjacent linear skeletons to establish the look-up table.

  • Patent number: 9943222
    Abstract: A laryngoscope with automatic image adjustment is revealed. The laryngoscope includes a laryngoscope body, a rotation assembly, a display and a sensor. The laryngoscope body is disposed with a fixing slot and is used for capturing an image. One end of the rotation assembly is fixed in the fixing slot while the other end thereof is arranged with the display. The display is rotated around the rotation assembly. The rotation assembly is set with a limiting slot. The sensor is electrically connected to a rear side of the display and is located inside the limiting slot. While the display being rotated, the sensor is slid on the surface of the rotation assembly. When the sensor is slid in the limiting slot, the display shows the image. Once the sensor is slid outside the limiting slot, the display shows a reflection of the image. Thus the image is adjusted automatically.

  • Publication number: 20160022131
    Abstract: A waterproof laryngoscope and a waterproof structure are revealed. The waterproof laryngoscope includes a laryngoscope body and a waterproof sleeve. The laryngoscope body consists of a handle and a camera tube. The handle has a fixing portion disposed with at least one stopper. The camera tube is fixed in the handle and extended out of the fixing portion. The waterproof sleeve is fitted over the camera tube and fixed on the handle. The waterproof sleeve includes a connection portion that is sleeved over the camera tube and fixed on the fixing portion. The connection portion is arranged with at least one fixing groove. The stopper is slid in the fixing groove and locked on a rear end of the fixing groove. Thereby not only patient's body fluid will not flow into the laryngoscope, patients are also protected from being affected by toxic chemicals and cross infection.

  • Patent number: 7742661
    Abstract: The present image processing apparatus includes a pixel arrangement controller and two data unit buffers coupled with the pixel arrangement controller. This controller can rearrange the addresses of the pixels in the corresponding data unit buffer according to the size of the block. Accordingly, the pixel data of the same block can be arranged in sequential addresses of the data unit buffer. Therefore, the pixel data may be processed as a batch.

  • Publication number: 20080180239
    Abstract: The invention discloses a photo meter comprising a light emitting device, a photo sensor, and a controller. The controller has a look-up table, wherein the look-up table records a plurality of control signals and a plurality of standard lightness values. The controller is used for transmitting a plurality of control signals for controlling the light emitting device to generate a plurality of lightness. The photo sensor is used for sensing the lightness to generate a plurality of corresponding lightness values. Afterward, the controller receives the lightness values from the photo sensor and then broadcasts an alert signal to notify the user that the photo sensor should be replaced if the difference between each of the lightness values and each of the corresponding standard lightness values recorded in the look-up table is greater than a threshold value.

  • Publication number: 20080158609
    Abstract: The invention discloses an apparatus for converting gray scale. The apparatus includes a receiving module, an encoding module, and a decoding module. The receiving module is used for receiving an input image, wherein the input image has an N-bit first gray level. The encoding module is used for selectively calculating a first color level based on both M higher bits and T lower bits of the first gray level, and then calculating a second color level and a third color level based on M higher bits of the first gray level. The decoding module is used for converting the first, second, and third color levels into an N-bit second gray level by using a gray scale conversion formula.
