| 20120086470 | CONSTANT IMPEDANCE LINE DRIVER WITH DIGITALLY CONTROLLED EDGE RATE - A constant impedance driver provides controlled output slew rates. The driver includes a plurality of buffers, each with an output impedance that is multiple of the output impedance of the driver. Outputs of buffers are coupled in parallel to form the output of the driver. Inputs to the buffers are coupled to an input signal or delayed versions of the input signal. The buffer inputs may be selectively coupled to taps of a delay line to provide selected slew rates on the output of the driver. The buffers may be selectively enabled to change or calibrate the output impedance of the driver. | 04-12-2012 |

| 20100238785 | Cancellation of Crosstalk Energy in Communication Loops - Systems and methods for reducing crosstalk are provided. In one implementation, a method is provided. The method includes applying a pilot signal to a disturber twisted pair and measuring near end crosstalk of a victim twisted pair. The coupling characteristics between the disturber and the victim twisted pair are determined. A far end crosstalk function is derived for estimating the far end crosstalk in the victim twisted pair using the determined coupling characteristics. A crosstalk reduction signal is determined using the estimated far end cross talk. The crosstalk reduction signal is injected into the victim twisted pair to reduce crosstalk in the victim twisted pair. | 09-23-2010 |

| 20090007805 | Needle with Air Duct - A baler has a bale chamber and a needle movable through the bale chamber to pass a strand of twine from one side of the bale chamber to a knotter located on the opposite side, the twine being engaged by a tip of the needle. In the invention, pressurized air is directed at the needle tip. The supply of pressurized air may be discontinuous and timed to coincide only with certain phases of the needle operating cycle. The air stream avoids crop material being caught up in the knots formed by the knotter. | 01-08-2009 |

| 20110120030 | Skylight screen - A screen for a skylight which is mounted on a substantially flat roof and which includes a frame having spaced apart vertical walls extending upwardly from the roof. The screen includes a plurality of longitudinal bars and a plurality of transverse bars secured thereto so as to form a plurality of rectangular openings. The transverse bars having a central portion forming an arch that is adapted to overlie the skylight. The transverse bars also include end portions having a substantially vertical section merging into the central portion and a substantially horizontal end section extending outwardly. The end sections are adapted to act as a foot allowing said screen to rest on and be supported by the roof. The transverse rods also include an intermediate section between the vertical section and the horizontal section that is spaced from the corner formed between the roof and each of the vertical walls of the skylight frame. A plurality of clips secure the vertical section of at least some of the transverse rods to the space apart vertical walls of the skylight frame. | 05-26-2011 |
