20090090846Imaging system with low noise pixel array column buffer - An imaging system includes a row and column array of active pixels, each having an associated pitch. In response to respective control signals, each pixel outputs a reset level which includes noise components, or a signal level which includes signal and noise components. Multiple column buffers, each having a pitch equal to or less than that of a pixel, convey the outputs of respective pixel columns to a bus line. Each buffer comprises ‘odd’ and ‘even’ S&H/CDS circuits, which process the pixel outputs of odd and even rows, respectively. Each S&H/CDS circuit subtracts pixel reset level from signal level to produce an output in which correlated noise is suppressed. Each column buffer includes a buffer amplifier which conveys the output to the bus line. A gain amplifier separate from the column buffers is coupled to the bus line such that it amplifies the outputs of a multiple column buffers.04-09-2009

20120125904WELDING NOZZLE - An exemplary welding nozzle has a smooth, highly polished bore of circular cross-section. The bore has a forward portion of generally flared, gradually curving shape, joined with a narrowing inner portion along a gradual curve. Hence a concentrated surface flow of shielding gas may be directed out the nozzle's mouth to reliably provide a flared shielding envelope having reinforced boundaries. The inner portion tapers inwardly at a constant angle for a length sufficient to dampen flow disturbances. Hence an inner core of shielding gas of high ionization potential may be directed in laminar flow out the nozzle's mouth for concentration immediately about the exposed electrode to stabilize the electric arc at the electrode tip. The diverging gas flows enable significantly reduced gas consumption while reliably maintaining weld quality, a reduced rate of spatter buildup within the nozzle, and increased versatility of welding tip operation in both automated and manual environments.05-24-2012

20120098798CONDUCTIVE BRUSH FOR USE WITH A COMPUTING DEVICE - A conductive brush, or stylus, for use with touch screen computing devices. The bristles or filaments are attached to an electrically conductive ferrule, so that even when the brush is pressed against the tablet to make the bristles splay apart, the conductive ferrule itself maintains electrical communication with the tablet. The brush thus allows users to conduct paint operations in an uninterrupted manner, even when its bristles spread apart. Further, this ferrule can be made removable so that users can swap out different brush heads quickly and easily. Additionally, the ferrule has at least a portion that is flexible, deforming visibly upon application of pressures commonly achieved during a typical painting operation. This deformation at least partially absorbs stresses on the filaments, preventing them from splaying apart excessively during painting, and thus helping to prevent loss of detection by the tablet and/or undesired visual effects.04-26-2012

20100023149COMPUTER AIDED DESIGN AND MANUFACTURING OF TRANSTIBIAL PROSTHETIC SOCKETS - For use in connection with evaluating prosthetic sockets (and other objects) designed and fabricated with computer aided design and manufacturing software, the shape of a socket is accurately scanned and digitized. The scanned data are then compared to either an electronic shape data file, or to the shape of another socket, a positive model of a residual limb (or socket), or a residual limb. Differences detected during the comparison can then be applied to revise the design or fabrication of the socket, to more accurately achieve a desired shape that properly fits the residual limb of a patient and can be used to solve the inverse problem by correcting for observed errors of a specific fabricator before a socket is produced. The digitizing process is implemented using a stylus ball that contacts a surface of the socket to produce data indicating the three-dimensional shape of the socket.01-28-2010
20100036455MEASUREMENT AND USE OF IN-SOCKET RESIDUAL LIMB VOLUME CHANGE DATA FOR PROSTHETIC FITTING - Changes in the volume of residual limbs on which prosthetic sockets are worn can be measured based on bioimpedance measurements along one or more segments of the limb. A current at an appropriate frequency (e.g., in the range from 1 kHz to 1 MHz) is injected at two current electrodes that contact the skin of the residual limb. The voltage at the voltage electrodes disposed between the current electrodes is measured and using an appropriate model, the change in the segmented volume of the limb can be determined during periods of different activity and at different times during the day. This information can be used for assessing the fit of the socket and can also provide a feedback signal for automatically controlling volume management devices, to ensure a more comfortable fit when the volume of the limb is changing.02-11-2010
