| 20120025813 | DETECTING INDUCTIVE OBJECTS USING INPUTS OF INTEGRATED CIRCUIT DEVICE - An system for detecting inductive objects includes an inductive sensor circuit for detecting changes in an electromagnetic field (“EMF”) environment and an integrated circuit (“IC”) device. The inductive sensor circuit generates an oscillating analog waveform with an envelope that indicates changes in the EMF environment. The oscillating waveform is coupled to the digital input pin of the IC. A digital interface circuit in the IC is coupled to the digital input pin and is configured for detecting if the oscillating waveform exceeds high and low threshold voltage levels. The detecting results in a digital pulse which represents changes in the EMF environment. In another implementation, a timer input capture pin can be used to detect the waveform envelope decay by storing the time when the waveform crosses a threshold value during a time period. A reduced capture time after the time period expires indicates a change in the EMF environment. | 02-02-2012 |

| 20080220463 | METHOD OF CELL CHROMATOGRAPHY - A method is provided of conducting cell chromatography with a group of cells. Each cell has a fluorescence intensity. The method includes the step of depositing the group of cells into a first chamber for a first predetermined time period such that a first portion of cells of the group of cells attaches to a first surface. The cells unattached to the first surface are removed from the first chamber and deposited into a second chamber for a second predetermined time period. A second portion of cells of the unattached cells attach to a second surface. The cells unattached to the second surface are removed from the second chamber. Thereafter, the fluorescence intensities of the cells attached to the first and second surfaces are compared to a standard. | 09-11-2008 |
| 20080255008 | GELATION CONTROLLED FLUID FLOW IN A MICROSCALE DEVICE - A method of self regulating a process of manufacturing a biological device which includes the steps of: choosing a first material and a second material based on a correlation of a parameter of the second material with a parameter of the first material; and merging the first material with the second material where the correlation of the parameter of the second material with the parameter of the first material self regulates the merging step to provide a distinct patterning of the first material and the second material. | 10-16-2008 |
| 20090051716 | METHOD FOR CONTROLLING COMMUNICATION BETWEEN MULTIPLE ACCESS PORTS IN A MICROFLUIDIC DEVICE - A method is provided of controlling communication between multiple ports in a microfluidic device. The method includes the step of providing a channel network in a microfluidic device. The channel network including a first channel having a first input port and an output port. The first channel is filled with a fluid and a first output droplet is deposited on the output port. The first output droplet has a radius of curvature. The first output droplet flows toward the first input port in response to placement of a first input droplet having a radius of curvature greater than the radius of curvature of the first output droplet on the first input port.

| 20090123961 | MICROFLUIDIC DEVICE HAVING STABLE STATIC GRADIENT FOR ANALYZING CHEMOTAXIS - A microfluidic method and device for testing and analyzing chemotaxis by providing a stable, static fluid gradient. The device includes a sink reservoir for receiving biological cellular material and a source reservoir for receiving a chemoattractant. The biological cellular material migrates through a low fluid volume microfluidic gradient channel located between the source and sink reservoirs. The fluid in the gradient channel is static and stable due to a high fluid volume closed circuit bypass microfluidic channel also in fluid communication with the source and sink reservoirs, whereby the bypass channel relieves any pressure differential imparted across the gradient channel. | 05-14-2009 |

| 20080264392 | Apparatus for an Internal Combustion Engine - An apparatus for achieving internal EGR in a four-stroke internal combustion engine which, for each cylinder, has at least one inlet valve and at least one exhaust valve for controlling the connection between combustion chambers in the cylinder and an inlet system and exhaust system respectively. A rotary camshaft with a cam curve is designed to interact with a follower member and has a first lobe portion for generating the normal exhaust valve lift of the engine. The camshaft is provided with a second lobe portion, which has a height measurement over and above its basic curve which falls short of the measurement for normal exhaust valve clearance when driving at low load and accompanying low heat development in the engine. As a result of thermal expansion in the valve mechanism, the height measurement exceeds the measurement for normal exhaust valve clearance when driving at high load and accompanying high heat development in the engine. The second lobe portion is situated within a crankshaft angular range of about 360-480 degrees. | 10-30-2008 |
| 20090301061 | LIMITING TRANSMISSION FUNCTION WHILE IN REGENERATION MODE FOR A DIESEL PARTICULATE FILTER - System and method for regenerating a diesel particulate filter in the exhaust system of an internal combustion engine driven vehicle that is equipped with an automatic mechanical transmission. The particulate load in the diesel particulate filter is determined to exceed a minimum predetermined threshold amount which is sufficiently high to warrant regeneration of the filter. Current vehicle conditions are determined to exist that permit the establishment of appropriate conditions in the exhaust system to affect regeneration of the particulate loaded filter by appropriately configuring the AMT. The immediate future driving conditions are analyzed to assure they permit operation of the combustion engine under sufficient load and at sufficiently low speeds to maintain a sufficiently high regeneration temperature and exhaust flow in the exhaust system under the control of the AMT to affect regeneration of the diesel particulate filter. Finally, successful regeneration of the filter is executed by appropriately configuring the AMT to cause the combustion engine to run in a manner that establishes a sufficiently high regeneration temperature and exhaust flow in the exhaust system and that is maintained for a prescribed period of time. | 12-10-2009 |
