| 20090217951 | APPARATUS AND METHOD FOR CLEANING A LIQUID HANDLING PROBE - The present invention concerns an improved apparatus for cleaning the interior of a liquid handling probe to reduce the amount time and the volume of wash fluid required to clean the probe and minimize carryover of material between different samples. In addition to the probe, the apparatus includes one or more wash fluid reservoirs, a compressed gas supply, one or more pumps, two or more valve-controlled probe lines and a controller for opening and closing the valves and actuating the pump(s) at desired time intervals. The invention further concerns a method of cleaning a liquid handling probe using the claimed apparatus and comprising sequential steps of pumping wash fluid and compressed gas through the probe. | 09-03-2009 |

| 20090305806 | PUTTER WITH AIMING ARMS - A golf putter includes a pair of aiming arms at each end of the putter head having opposite and inward facing arcuate surfaces corresponding to the outline of a golf hole. The aiming arms may be removed manually or may be made to pivot. In the latter, each arm is pivotally connected at opposing ends of the putter head and adapted to pivot about an axis between a forward aiming position and a second position away from the forward aiming position. Control of the rotation of the aiming arms may be by a lever operable from the putter shaft, or by a spring actuated by pushing downward on the putter shaft. | 12-10-2009 |
| 20090305813 | PUTTER WITH PIVOTING AIMING ARMS - A golf putter comprising a shaft, a putter head attached along a top surface to the shaft, the head including an elongated body having a central axis along the length of the body. The golf putter includes a pair of aiming arms, each arm pivotally connected at opposing ends of the elongated body and adapted to pivot about the central axis between a forward aiming position and a second position away from the forward aiming position. The golf putter also includes a lever adapted to control rotation of the aiming arms from the forward aiming position to the second position, the lever operable from a portion of the shaft. | 12-10-2009 |

| 20090075595 | High-Speed System Having Compensation for Distortion in a Digital to-Analog Converter - A method and system for the design and implementation of an inverse-sinc function that can efficiently process signals produced by high-speed systems is presented. An integrated inverse-sinc module accepts multiple data streams that may result from parallel sub-systems and creates multiple outputs that can be interleaved to produce a sequence that has been filtered by an inverse-sinc function. The multiple-input, multiple-output system may be beneficially operated at a low data rate, such as the data rate used by each of the sub-systems. | 03-19-2009 |
| 20100100576 | Desensitized Filters - A method and system for the design and implementation of filters is presented in which the filter's transfer function can be provided with a significant insensitivity to the filter's tap coefficient values. A desensitized digital filter includes a first halfband filter and a second filter coupled in cascade between an input of the digital filter and the output of the digital filter. In embodiments, the first filter has the transfer function F(z)=K(1+z | 04-22-2010 |
| 20100235420 | Desensitized Filters with Droop Correction - A method and system for the design and implementation of desensitized digital filters with droop correction. The desensitized digital filter includes a first filter configured to receive an input signal, a decimator or upsampler, and a modified desensitized half-band filter. The first filter introduces droop into the passband of the desensitized digital filter. The desensitized half-band filter has a transfer function F(z)=K(1+z | 09-16-2010 |
