Publication number: 20130231971Abstract: A computer-implemented system for developing, tracking and managing legal (and other professional services) projects or matters through the Legal Project Management (LPM) process. The LPM process divides the management of a legal matter or project into three phases: Project Development; Project Execution; and Project Closure. The Project Development Phase includes conflict screening, fee arrangements, identification of the nature and scope of the matter, the goals of the stakeholders, the tasks associated with the matter, and development of a schedule, budget, and a communications plan. The Project Execution Phase involves monitoring the progress of the matter, tracking the actual time and cost to budget, identifying risks and changes to the scope of the matter as they develop, and communicating among team members. The Project Closure Phase includes file closure procedures, and team and client meetings to identify lessons learned in the engagement for future improvement.Type: ApplicationFiled: August 23, 2012Publication date: September 5, 2013Inventors: JUDY BISHOP, Mike Burks, John Christenson, Paul Davis, Felicia Morris, William Painter, Jennifer Reese, David Rueff, Meredith Williams, Conda Winchester

Publication number: 20070048888Abstract: A method for making a subsurface electrical contact on a micro-electrical-mechanical-systems (MEMS) device. The contact is formed by depositing a layer of polycrystalline silicon onto a surface within a cavity buried under a device silicon layer. The polycrystalline silicon layer is deposited in the cavity through holes etched through the device silicon and reseals the cavity during the polycrystalline silicon deposition step. The polycrystalline silicon layer can then be masked and etched, or etched back to expose the device layer of the micromachined device. Through the layer of polycrystalline silicon, a center hub of the device may be electrically contacted.Type: ApplicationFiled: August 29, 2005Publication date: March 1, 2007Inventor: John Christenson

Publication number: 20060207328Abstract: A three-axis accelerometer is provided for sensing acceleration in three orthogonal axes. The accelerometer includes a support substrate, fixed electrodes having fixed capacitive plates fixed to the support substrate, and a movable inertial mass having movable capacitive plates capacitively coupled to the fixed capacitive plates.

Publication number: 20060155663Abstract: Systems, devices, methods, and software are provided that are suitable for use in the creation, implementation, use and/or refinement of treatment protocols. The software is configured for use in a client-server environment where the server communicates with client devices such as PDAs, laptops, tablets, or desktop computers. The software is directed to programming for basing an assessment of risk of bacterial infection in a subject on the presence, or lack, of viral illness in that subject. The diagnosis of viral illness is made through the use of results obtained from an enterovirus polymerase chain reaction test or a direct fluorescent assay test for respiratory viruses. Such test data, in conjunction with ‘time to positivity’ data for urine, blood, cerebrospinal fluid, or other cultures, is then processed by the software to assess the individual risk of occurrence of various conditions, such as bacterial infection, in a particular subject.Type: ApplicationFiled: February 7, 2003Publication date: July 13, 2006Inventors: Carrie Byington, Andrew Pavia, John Christenson

Publication number: 20050093533Abstract: The present invention involves an electrical verification method that detects moisture within the cavity of the semiconductor or micro-machined device. The method affects an increase in the time for sufficient water vapor to remain within an unsealed device, so that instability in the diode can be measurable over a longer period of time. The method begins with the step of forming at least one reservoir on at least one of the device wafer and the capping wafer. The at least one reservoir connects to at least one diffusion channel, which is in communication with at least one reservoir port. The method further includes the steps of forming a PN junction diode adjacent to the at least one reservoir port; bonding the device wafer with the capping wafer to form a cavity; and electrically testing the PN junction diode as an indication of the presence of moisture within the cavity.Type: ApplicationFiled: October 15, 2003Publication date: May 5, 2005Inventors: John Christenson, David Rich

Publication number: 20050064619Abstract: A process using integrated sensor technology in which a micromachined sensing element and signal processing circuit are combined on a single semiconductor substrate to form, for example, an infrared sensor. The process is based on modifying a CMOS process to produce an improved layered micromachined member, such as a diaphragm, after the circuit fabrication process is completed. The process generally entails forming a circuit device on a substrate by processing steps that include forming multiple dielectric layers and at least one conductive layer on the substrate. The dielectric layers comprise an oxide layer on a surface of the substrate and at least two dielectric layers that are in tension, with the conductive layer being located between the two dielectric layers. The surface of the substrate is then dry etched to form a cavity and delineate the diaphragm and a frame surrounding the diaphragm.Type: ApplicationFiled: September 30, 2004Publication date: March 24, 2005Inventors: Abhijeet Chavan, James Logsdon, Dan Chilcott, John Christenson, Robert Speck
