  • Publication number: 20090159778
    Abstract: A solar energy absorption plate with an angle adjusting assembly comprises a solar energy plate; a first light sensing element and a second light sensing element at two symmetrical opposite sides; a control unit connected to each of the first light sensing element and second light sensing element; an angle adjusting unit connected to the control unit; and the angle adjusting unit being interactive with the solar energy plate. The control unit calculates a brightness difference between a brightness of the first light sensing element and a brightness of the second light sensing element so as to drive the angle adjusting unit to cause that the first and second light sensing element in the solar energy plate have the same brightness and the solar energy plate facing to sun. Furthermore a third and a fourth light sensing elements can be used further.

  • Patent number: 6448014
    Abstract: The present invention provides a method of determining latent HIV infection by detecting low-abundant HIV nucleic acid sequences in samples of cellular DNA or in paraffin-fixed tissue sections or frozen sections. This technique calls for one primer for an Alu sequence in the human chromosomal DNA and the other primer near the end of the viral LTR. PCR-amplified DNA is then hybridized with a probe which only recognizes the amplified LTR sequence. This probe could be labeled in different ways, and quantitative assays for latent HIV or other retroviruses infection could be developed.
