| 20100057372 | RAPID IDENTIFICATION OF PROTEINS AND THEIR CORRESPONDING SOURCE ORGANISMS BY GAS PHASE FRAGMENTATION AND IDENTIFICATION OF PROTEIN BIOMARKERS - Embodiments of the present invention relate to the identification of proteins using laser desorption ionization mass spectrometry, the identification of source organisms comprising the identified proteins and a computer readable storage medium storing instructions that, when executed by a computer cause the computer to perform a method for the identification of proteins using mass spectra generated through the application of laser desorption ionization mass spectrometry of the proteins. | 03-04-2010 |

| 20100033542 | CONTINUOUS INKJET PRINTING SYSTEM AND METHOD FOR PRODUCING SELECTIVE DEFLECTION OF DROPLETS FORMED FROM TWO DIFFERENT BREAK OFF LENGTHS - A continuous inkjet system and method has a stimulation device producing a modulation in a liquid jet having a wavelength λ and causing a first liquid droplet to break off from the liquid jet and travel along a path and causing a second liquid droplet to break off from the liquid jet and travel along the path. The first liquid droplet has a first break off length and the second liquid droplet has a second break off length longer than the first break off length. The first break off length and the second break off length have a difference of at least one wavelength λ in response to stimulation pulses. A charge electrode produces a charge differential between the first liquid droplet and the second liquid droplet, and a deflection mechanism causes trajectories of the first liquid droplet and the second liquid droplet to diverge so that a trajectory of one droplet of the first and second liquid droplets causes the one droplet to be directed for collection and prevented from depositing on the surface and a trajectory of the other droplet of the first and second liquid droplets causes the other droplet to be directed for depositing on the surface. A stimulation controller identifies a transition in droplet creation between a stimulation cycle that is to produce a droplet having a second break off length and a stimulation cycle that is to produce a droplet having a first break off length and introduces a skip cycle between the stimulation cycle that is to produce the droplet having a second break off length and the stimulation cycle that is to produce the droplet having the first break off length. | 02-11-2010 |
| 20100033543 | CONTINUOUS INKJET PRINTING SYSTEM AND METHOD FOR PRODUCING SELECTIVE DEFLECTION OF DROPLETS FORMED DURING DIFFERENT PHASES OF A COMMON CHARGE ELECTRODE - A continuous inkjet system includes a plurality of nozzles producing a respective liquid jet through each nozzle. A stimulation device at each nozzle is responsive to different types of stimulation signals to produce a modulation in the respective liquid jet to selectively control droplet break off relative to phases of the cycle of a varying voltage source that is connected to a charge electrode. The break off phase of a droplet relative to the voltage phase of the voltage source will determine whether the droplet is charged or not charged. Droplets that become charged may be deflected from their paths and a deflection mechanism including the charge electrode determines which droplets are allowed to reach a surface for say printing and which droplets are collected and not deposited upon the surface. | 02-11-2010 |

| 20080284827 | CONTINUOUS INK JET PRINTER WITH MODIFIED ACTUATOR ACTIVATION WAVEFORM - A drop generator is operated to form large-volume and small-volume droplets by providing a droplet generator having a nozzle and an adjustable stimulation device; supplying liquid to the droplet generator such that a stream of diameter D emanates from the nozzle; activating the stimulation device to produce a first set of perturbations on the liquid stream, the perturbations having a period x such as to cause the liquid stream to form into small-volume droplets; selectively adjusting the stimulation device to produce a second set of perturbations on the liquid stream, the second set of perturbations having a period Nx such as to cause a segment of the liquid stream to form into a large-volume droplet, whereby the large-volume droplet is N times the volume of the small-volume droplets; and further adjusting the stimulation device to produce a third set of perturbations on the liquid stream during the period Nx. | 11-20-2008 |
