    摘要: A system and method for determining the impedance of a telephone transmission line are disclosed. A test signal is transmitted through a telephone switch to the telephone line and corresponding echo signals are monitored. The test and echo signals are correlated to derive an impulse response. A transfer function for the system is calculated from the impulse response. Then, a transfer function for the transmission line is derived using the system transfer function and the transfer function of the telephone switch. Finally, the transmission line impedance is calculated from the transmission line transfer function. Once the transmission line impedance is known, an impedance matching circuit for the telephone switch can be modified to match the transmission line and the switch.

    摘要: A retention structure for retaining a recessed lighting fixture behind a ceiling includes an attachment structure that has a first wall and a second wall. The attachment structure is designed to be attached to a housing of a recessed light fixture. The retention structure further includes a screw attached to the first wall of the attachment structure and to the second wall of the attachment structure. The retention structure also includes a pawl attached to the threaded screw. The pawl is rotatable along with the threaded screw. The pawl is also axially movable along the threaded screw between the first wall of the attachment structure and the second wall of the attachment structure.

    摘要: Disclosed herein are novel alleles characterized by polymorphisms in sulfotransferase genes. The alleles may be used to genetically type animals for sulfotransferase activity. In a preferred embodiment, the alleles may be used as markers for boar taint in pigs. Methods for identifying such markers, and methods of screening animals to determine those more likely to produce desired characteristics and preferably selecting those animals for future breeding purposes are also disclosed.
