  • Publication number: 20200178924
    Abstract: Introduced here are electronic stethoscope systems designed to simultaneously monitor sounds originating from within a body under examination and the ambient environment. An electronic stethoscope system can include one or more input units that are connected to a hub unit. Each input unit may have at least one auscultation microphone and at least one ambient microphone. To improve the quality of sound recorded by an input unit, a processor can apply a noise cancellation algorithm that considers as input the audio data produced by the auscultation microphone(s) and the audio data produced by the ambient microphone(s). The audio data may be digitized directly in the input unit, and then transmitted to the hub unit for synchronization. For example, by examining the audio data produced by the ambient microphone(s), the processor may discover which digital artifacts, if any, should be filtered from the audio data produced by the auscultation microphone(s).

  • Patent number: 9462245
    Abstract: A method for image correction and image projection apparatus using the same are provided, where the image projection apparatus scans a projection light beam on a projection plane to form an image. The image correction method includes the following steps. A plurality of projection points of the projection light beam on the projection plane are sampled to define a projection coordinate system. An image projection area is defined on the projection coordinate system. The projection light beam is moved to scan on the projection plane and projected to the projection points sequentially. Whether the projection point is located in the image projection area is determined. When the projection point is located in the image projection area, a corrected image information is provided to the projection point.

  • Patent number: 9350960
    Abstract: A method for manipulating a laser projection device is provided. A laser projection device comprising a laser source, a driving module and a scanning mirror module is provided. The laser source provides a laser beam. The scanning mirror module disposed at one side of the laser source reflects the laser beam, so that the laser beam performs a scanning motion to form a projection track on a projection region. According to a projection distance, the driving module provides a first drive signal to modulate the number of scanning times of the scanning mirror module and provides a second drive signal to control the on/off time of the laser source to adjust an initial image resolution to a corresponding image resolution lower than the initial image resolution to maintain the frame quality of laser projection. The projection distance is a distance between the laser source and the projection region.

  • Patent number: 9028072
    Abstract: A laser projection system comprising a laser light and a human body detection module is disclosed. The laser light source emits a laser light. The human body detection module detects a reflective light of the laser light irradiated on an object. The human body detection module determines whether the object is a human according to a relationship between several reflectivity indexes of the reflective light. If the relationship corresponds to predefined situation, the human body detection module reduces a laser output intensity of the laser light.

    Abstract: A speckle contrast reducing method for a laser scanning projection system includes the following steps. Firstly, a laser beam is provided. The laser beam is projected on a projection surface according to a first scanning trajectory, thereby generating a first image frame. Sequentially, the laser beam is projected on the projection surface according to a second scanning trajectory, thereby generating a second image frame at an image refresh rate. Moreover, the second scanning trajectory of the second image frame is shifted by a displacement from the first scanning trajectory of the first image frame along a slow-axis direction.
