摘要:
An apparatus for interconnecting a fiber-optic network and a coax network comprising a coax line terminal (CLT) configured to couple to an optical line terminal (OLT) at the fiber-optic network and a plurality of coax network units (CNUs) at the coax network and to cache data received from the CNUs and forward the cached data to the OLT upon receiving a message from the OLT that assigns a transmission cycle for a specified CNU, wherein the CLT forwards the cached data to the OLT upon receiving the message regardless of whether the cached data corresponds to the specified CNU.

A digital data presenting apparatus having a lighting system and a camera system is provided. The lighting system is used to emitting a light and further includes a lens assembly for controlling the light to the projection area of an object. The camera system further includes an image-sensing component, a camera lens positioned on one side of the image-sensing component and a first deflector adjusting a propagation direction of the light reflected from the object to be displayed to the image-sensing component through the camera lens.

A zoom-lens structure for a camera is disclosed which comprises at least an outer cylinder, an inner cylinder, a fastening ring and a lens mount assembly. The outer cylinder has a plurality of straight grooves for engaging with a plurality of projected keys, respectively, provided on a fastening ring so as to allow the fastening ring to be movably mounted outside the inner cylinder. The lens mount assembly includes a first lens mount and a second lens mount, and the fastening ring has at least two first positioning pieces to be engaged with positioning grooves provided on the second lens mount so as to limit the second lens mount from rotating. At least two second positioning pieces are provided on the first lens mount which are also engaged with the positioning grooves and are thus controlled by the second lens mount from being able to rotate. This arrangement controls the entire lens mount assembly to move back and forth along an optical axis to provide a zoom lens function. In a preferred embodiment, the inner surface of the inner cylinder is furnished with a plurality of curved grooves for receiving corresponding rolling balls, respectively, provided on outer surfaces of the first lens mount and the second lens mount. The zoom-lens structure so disclosed allows the focal length to be varied with only three cylinders having relatively small diameters without affecting the retracting length of the lens assembly.
