摘要： The unit for retaining/securing a fiber optic cable comprises an enclosure including a tray having a back base plate, a top and a bottom sides and a unit for retaining/securing a fiber optic cable, disposed in an interior of the enclosure. The bottom side is provided with a pair of identical apertures. Each aperture resembles to a flat shovel having an upper rectangular shape continued by a circular sector; the aperture is so profiled as to engage alternatively a biting-retaining fixture for inserting a cable or an exit grommet for a leaving cable; the former is made of a rigid plastic, while the second—of a soft, elastic polymer. The unit for retaining/securing a fiber optic cable is actuated by a shifting lever, having a shape of an angled, cantilevered part with a longitudinal axis of symmetry bent generally at 90 degrees.

摘要： In some implementations, legibility of an image may be automatically determined based, at least in part, on text contained in the image. For example, image analysis techniques may be used to identify text components in an image. One or more features of each text component may be determined for use in assessing the legibility of the text component. For example, a classifier trained on the one or more features may provide a confidence level indicative of the legibility of each text component. The confidence level for each of the text components may be compared to a legibility threshold for determining whether the text component is legible or illegible. Based, at least in part, on the determination as to how much of the text in the image is legible or illegible, an overall legibility of the image may be assessed.

摘要： A method and system for acquiring the attitudes of an acetabulum and a femoral head in real time during an artificial hip joint replacement procedure; during hip joint replacement, a pressure sensor and/or a touch sensor are disposed at each pressure point concerned for a femoral head prosthesis test mould, forming a sensor array (1); the sensor array (1) acquires the contact and stress conditions between the femoral head prosthesis test mould and the acetabulum, and sends out a signal; and a receiving terminal receives and displays the signal on a display module, and acquires the simulated attitudes of the acetabulum and the femoral head. The system comprises a sensor array (1), a necessary peripheral circuit, and a signal receiving and display device for receiving and displaying the signal sent by the peripheral circuit. The present invention can accurately simulate the presented attitude of the femoral head prosthesis during hip joint replacement procedure, so that a doctor can intuitively see the position and movement condition of the femoral head prosthesis during the procedure, thus improving the success rate and curative effect of the hip joint replacement procedure.
