  • Patent number: 11954787
    Abstract: The disclosure provides image rendering methods and apparatuses. One example method includes that a foreground image is first rendered, and then a panoramic image used as a background is rendered. A pixel corresponding to the foreground image has a corresponding depth value. When the panoramic image is rendered, content corresponding to the panoramic image may be rendered at a pixel corresponding to a depth standard value based on a depth value of a pixel on a canvas. The depth reference value is a depth value of a pixel other than the pixel corresponding to the foreground image.

  • Publication number: 20240105351
    Abstract: A method for measuring drop time of a control rod cluster integrated with a rod position measurement device is provided, wherein the method is used to measure the drop time of each control rod cluster, and includes: Si, monitoring a voltage Ua of coils in Group A to capture a rod cluster drop signal; S2, searching a point (tmax, Vmax) with a maximum drop speed or with a local maximum drop speed; S3, retroactively calculating, from tmax, an end of a time period T4 when the control rod cluster starts to drop; S4, retroactively searching, from a minimum value point of a drop reference signal DROPref, a start of the time period T4 when the drop reference signal DROPref drops from a maximum value to 33% thereof; and S5, determining, from tmax forward, a time point t6 when a drop speed of the control rod cluster is lower than 0.

  • Patent number: 11710266
    Abstract: Embodiments of this application provide a rendering method and apparatus, and the like. The method includes: A processor (which is usually a CPU) modifies a rendering instruction based on a relationship between a first frame buffer and a second frame buffer, so that a GPU renders a rendering job corresponding to the first frame buffer to the second frame buffer based on a new rendering instruction. In this application, render passes of one or more frame buffers are redirected to another frame buffer. In this way, memory occupation in a rendering process of an application program is effectively reduced, bandwidth of the GPU is reduced, and power consumption can be reduced.

  • Publication number: 20220327758
    Abstract: This application discloses an image rendering method in a panoramic application. In the method, a foreground image is first rendered, and then a panoramic image used as a background is rendered. A pixel corresponding to the foreground image has a corresponding depth value. When the panoramic image is rendered, content corresponding to the panoramic image may be rendered at a pixel corresponding to a depth standard value based on a depth value of a pixel on a canvas. The depth reference value is a depth value of a pixel other than the pixel corresponding to the foreground image. In this way, repeated rendering is avoided for an overlapping part between the foreground image and the panoramic image, which not only reduces resource wastes and rendering overheads, but also improves rendering efficiency.

  • Publication number: 20100145169
    Abstract: Methods and systems for detecting and alerting one to a condition of Compartment Syndrome provide for determining concentration data of biochemical compounds in tissues, preferably at a shallow depth beneath the skin; analysing the concentration data to detect a condition of Compartment Syndrome; and triggering an alarm if a condition of Compartment Syndrome is detected. The concentration of biochemical compounds may be measured using Near Infrared Spectroscopy. The biochemical compounds may comprise at least one compound from the group consisting of Hemoglobin, Oxygenated Hemoglobin, Cytochromes and Myoglobin.

  • Publication number: 20100127627
    Abstract: Apparatus and methods are provided for guarding against unintended exposure to light from a light-emitting device used to direct light to a subject for detection by a light detector. A sensor signal indicative of light detected by the light detector is sampled. An inhibition signal for inhibiting emission of light from the light-emitting device is generated, based at least in part on whether emitted light is expected from the light-emitting device and the comparison of the sampled sensor signal value to a threshold value. The light-emitting device may be monitored for continuous wave operation. A mechanical interlock may be provided having a guard moveable between closed and open positions respectively to cover and expose a port of the light-emitting device.

  • Publication number: 20100084557
    Abstract: A system for near infrared spectroscopy includes a controller that automates selection of light intensities for one or more light sources. The system may stepwise increase or decrease a current driving a light source until a signal received at a light detector is within a desired range. The system may maintain closed loop control over the intensity of a light source after the intensity has been set. The closed loop control may be based on a signal from a second light detector that senses light from the light source. Current/intensity settings may be established for each of multiple light detectors. In response to selection of a light detector, the corresponding current may be delivered to drive the light source.
