A system for processing DRM-enabled files includes a playback device and a software module. The software module includes a license-downloading module, a license-transforming module, a decryption module and an encryption module. The license-downloading module is configured to download a first license from a license server to a computer. The license-transforming module is configured to convert the first license to a second license. The decryption module is configured to decrypt a first DRM-enabled file of the computer into a raw file with a first decryption key. The encryption module is configured to encrypt the raw file into a second DRM-enabled file with a second encryption key. The playback device is configured to decrypt the second DRM-enabled file with the second license. The method of the system is also provided.
摘要:
An enhanced plane light source has a luminescent layer independently disposed in each recess formed on a light-transmittable substrate, so that field emission electrons directly impact the luminescent layer to produce light, which is not shielded by the cathode. The enhanced plane light source also includes a substrate forming a bottom structure thereof. The bottom substrate has a metal reflection surface to increase the reflectivity and upgrade light-emitting efficiency and luminous intensity. The recesses on the light-transmittable substrate have an approximate semi-circular or semi-parabolic cross section to increase the high field region at the cathode and the effective luminescent area at the anode, so that the luminous intensity and evenness are also largely increased.

The present invention concerns an on-the-fly long-running rotary filtration screen comprising a rotating split-flow bar, a filtration sleeve, filtration screen, a large gear, a small gear, a motor, a stop disc, two square keys, a outlet housing and a residue-removing rod. The main feather of the present invention is to employ the filtration bar to rotate continuously, mix and transport the plastic raw material toward the space formed between the split-flow and the filtration sleeve, thereby allowing the plastic raw material to flow into the conical hole and to be discharged from the funnel-shaped outlet of the outlet housing. When the motor is actuated, the hydraulic cylinder is also actuated with the motor. The action of the hydraulic cylinder causes the round rod to move forward, which in turn causes the filtration bar to move forward to a certain distance and backward to its original position, thereby generating a reciprocating action. Meanwhile, the plastic raw material is being mixed and stirred continuously, the action of transportation causes extraneous matters to be pushed into the space of the residue-removing thread and the guide bar is inserted into the guide bar slot, which is equipped in the residue-removing bar, to cause the residue-removing bar to rotate continuously, the action causes the extraneous matters to be pushed outward, thereby allowing the extraneous matters accumulated inside the space of the residue-removing thread to be discharged from the main housing, thus allowing the filtration device to operate continuously without stopping.

The present invention discloses a method for expressing multiple recombinant proteins in transgenic non-human mammalian milk, characterized in which human clotting factor IX gene and porcine lactoferrin gene are transferred into the mammal by gene injection and embryonic implantation to obtain expression in the milk of transgenic mammal and its filial generation. The method of this invention can maintain the stable expression of multiple recombinant proteins in the transgenic mammal during lactation and stable expression amount proximate to that of the first generation in the offsprings of the transgenic non-human mammal.

A tape measure includes an enclosure including an upper unit and a lower unit each defining a notch communicating with each other. The upper unit forms a protrusion. Poles are respectively formed on the upper unit and the lower unit adjacent the notches. The upper unit forms a pair of latches on opposite sides of the notch. The lower unit forms a pair of pivots on opposite sides of the pole. A springloaded tape cartridge is accommodated in the enclosure and includes a wheel, a gasket, and a gear. The first and second elastic members are respectively rotatably attached to the pivots of the lower unit. One end of each elastic member engages with the gear. The button is disposed at the notches of the enclosure. A pair of projections is formed on the button and presses opposite ends of the first and second elastic members respectively.

A backlight module (3) includes a light guide plate (2) and a light source (36). The light guide plate includes a light guide portion (20) and a frame portion (22) integrated with the light guide portion. The light source is arranged within the light guide portion. The light guide portion includes a light incident surface (240), a top surface (244) adjacent to the light incident surface, and a bottom surface (242) adjacent to the light incident surface. Each of the top and bottom surfaces may include an array of light diffusion concavities (246) or protrusions. The backlight module has a simple, reliable structure, and the cost of manufacture and assembly is reduced. In addition, the backlight module has improved light utilization.
