Methods, apparatuses, and computer program products for implementing interactive applications by storing and retrieving streaming video clips and associated metadata are described.

Interactive applications implemented in video streams

A method for delivering media from a server to a client device over a network is disclosed. An Virtual-Reality (VR) scene application running on the server generates a virtual VR 3D environment containing 3D models. The server checks the status of each 3D model in a predetermined order, and then, only those 3D models which are not pre-stored in the client device will all be rendered by the server into a left eye frame and a right eye frame of 2D video stream. The server then sends to the client device the frames and meta data of the 3D models which are pre-stored in the client device via the network. The client device uses a combined VR frame of these frames as a background for rendering the 3D models which are pre-stored in the client device so as to generate a mixed VR frame of video stream for output.

An enhanced door lock is capable of being locked from an inner side of a doorplate. At the outer lock portion, a ring seat and a C ring clamp two sides of the outer plate of the doorplate so as to enhance the structure of the doorplate to prevent the door lock from being pulled out. The inner cover is installed with a positioning hole. One side of a top of the control knob is drilled with a stud receiving groove. A positioning pin is placed in a stud receiving groove. The outer sleeve and the stud of the positioning pin are coupled with the stud receiving groove; then the bead resisting against the spring exactly pushes the positioning groove of the stud to resist against a positioning groove. By this structure, the lock is locked from the inner side of the doorplate.

A complex cooling fan includes an upper fan including an upper fan and a lower fan, the upper fan including a first cylindrical body, a plurality of first blades extending outwardly from the cylindrical shell body, and a cylindrical collar extending downwardly from the first cylindrical shell body, the cylindrical collar having a smaller diameter than the first cylindrical shell body, a lower edge of the first cylindrical shell body being formed with a positioning notch, and a lower fan including a second cylindrical shell body and a plurality of second blades extending outwardly from the second cylindrical shell body, the second cylindrical shell body having same outer diameter as the first cylindrical shell body and having an upper edge formed with a protuberance configured to engage with the positioning notch of the first cylindrical shell body, an inner diameter of the second cylindrical shell body having same size as an outer diameter of the cylindrical collar, the cylindrical collar being fitted into the second cylindrical shell body with the positioning notch engaged with the protuberance and the first blades aligned with second thereby combining the upper and lower fans together, whereby the complex cooling fan has increased cooling capacity and the molds for manufacturing the fan can be prolonged in service life thereby reducing the manufacturing cost.

Complex cooling fan with increased cooling capacity

Disclosed is a process for preparing Li.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 ceramic sintered bodies. Lithium fluoride powder is added to a calcined Li.sub.2 O--Al.sub.2 O.sub.3 --SiO.sub.2 powder prepared by sol-gel process as sintering agent. The resulting powder mixture is compressed into a molded article and sintered at a temperature of 950.degree.-1250.degree. C. to obtain the sintered bodies of the invention. The sintered bodies according to the present invention have a relative density of 97.9% and a thermal expansion coefficient of 10.sup.-7 /.degree.C. magnitude.
