The invention relates to a display device with a directional backlight. Stereoscopic images are produced by emitting light within two defined and restricted angular cones. Light is alternately sent to the viewer's left and right eyes in synchronization with switching the left and right eye images on the high-speed switching LCD. Alternatively, images can be generated for two or more observers and directed in multiple directions. The display device comprises a display panel (1), a light redirecting element (8) for guiding light through the display panel (1), a light guide (6) for guiding light towards the light redirecting element (8), A first light source (4) coupled to the light guide (6) to couple light into the light guide (6) in a first direction, and a second light source (5) coupled to the light guide (6) to couple light into the light guide (6) in a second direction Light is coupled into the light guide (6). The light redirecting element (8) has a first groove structure (9) and the light guide (6) has a second groove structure (7), the first and second groove structures (9, 7) being arranged in the following structure, The structure can guide the light from the first light source (4) through the display panel (1) with the first angular distribution (2), and guide the light from the second light source (5) through the display panel (1) with the second angular distribution (3). through the display panel (1).

A frequency transverter (10) and method for enabling bi-frequency dual-directional transfer of digitally encoded data on an RF carrier by translating between a crowded or otherwise undesirable first frequency band, such as the 2.4 GHz ISM band, and a less-crowded or otherwise desirable second frequency band, such as the 5.0 GHz-6.0 GHz U-NII band. In a preferred embodiment, the transverter (10) connects between an existing data radio (11) and its existing antenna (30), and comprises a bandswitch (12); an input RF isolating device (14); a transmuter (16); a converter (18); a dual output local oscillator (20); an output RF isolating device (22); and an antenna (24) tuned to the second frequency band. The bandswitch (12) allows for bypassing the transverter (10), thereby facilitating its use with legacy systems. The transmuter (14) and converter (16) are adapted to convert to and from, respectively, the second frequency band.

The invention provides a DNA (Deoxyribonucleic Acid) probe library hybridized with BRAF (v-Raf murine sarcoma viral oncogene homolog B1) gene. The DNA probe library comprises one or more DNA probes which can be hybridized with the BRAF gene, each DNA probe comprises the following sequences: SEQ ID NO.1, SEQ ID NO.2, SEQ ID NO.3, SEQ ID NO.4, SEQ ID NO.5, OR SEQ ID NO.6. The invention also provides a method for enriching BRAF gene segments by adopting the same. Based on this, the invention further provides a method for detecting the gene mutation of the BRAF gene. The BRAF gene segments can be enriched by thousands of times through adopting the method, the BRAF gene segments can be used for next-generation sequencing technology for detecting gene structure mutation including single base mutation, mRNA deficiency or increase, mRNA structure transversion and mRNA splicing change.

A process for preparing the prefabricated gradient optical fiber rod from polymer includes such steps as adding trigger and chain transferring agent to high-purity methyl methylacrylate, prepolymerizing until the transversion rate is 8-20%, adding it in a stainless steel container or glass tube with one closed end, high-speed rotating to obtain a methyl polymethylacrylate layer on inner surface, adding trigger, chain transferring agent and doping agent to another high-purity methyl methylacrylate, and continuously repeating said steps. Its advantages are large size and controllable refractivity curve.
