    摘要： A light diffuser for use on a camera strobe/flash unit either on camera or off. The diffuser has a main body with a base and is composed of a non-transparent material. The diffuser splits the single light source into two directions sending light into a pair of wings/cowls that are removably mounted to the main body. Inside the diffuser main body is a light-splitting reflector with a reflective surface to add an amount of specular and focused light towards the two cowls. The wings/cowls create two soft light sources. Further, the wings/cowls may have other shapes, colors, features such as holes, outlets, etc., to create additional light sources of soft light. The wings/cowls may also be colored to adjust the projected diffused light therefrom. The base of the half-cylindrical main body may include a plurality of contact arms adapted to grip the photographic light source.

    摘要： The present invention relates to an optical fiber access network and a communication protection method thereof. The optical fiber access network comprises an optical fiber communication system, a wireless communication system, a communication service switch device, a second optical network unit and a protection optical fiber. The wireless communication system is introduced to protect the optical fiber between the optical branching divider and the optical network unit in the optical fiber communication system. The protection optical fiber or the wireless communication system is used to protect the communication service respectively when there is a broken failure between the optical line terminal and the optical network unit in the optical fiber communication system. This invention overcomes the limit of the resource, protects communication service of the optical fiber communication system and improves the bandwidth utility of the communication system.

    摘要： A method of measuring the elastic modulus and hardness of a thin film on substrate using nanoindentation technique is provided. The method includes calculating a series of experimental corrected stiffness and contact radius pairs associated with one or more presumed parameters and information obtained from a loading curve associated with the thin film and substrate. Also, the method includes calculating a series of theoretical corrected stiffness and contact radius pairs associated with the same one or more presumed parameters and information obtained from the loading curve associated with the thin film and substrate. Furthermore, the method includes using results obtained from the experimental and theoretical corrected stiffness and contact radius pairs to compute the elastic modulus and hardness of the film material.

    摘要： This invention provides a method to identify compounds potentially useful for the treatment and prevention of neoplasia in mammals. The phosphodiesterase inhibitory activity of a compound is determined along with its ability to elevate JNK kinase activity. Growth inhibitory and apoptosis inducing effects on cultured tumor cells are also determined. Compounds that exhibit phosphodiesterase inhibition, an ability to elevate JNK kinase activity, growth inhibition and apoptosis induction are desirable for the treatment of neoplasia.
