Abstract: Methods for rotationally aligning transcatheter heart valve prosthesis within a native heart valve include percutaneously delivering the transcatheter heart valve prosthesis to the native heart valve, wherein the transcatheter heart valve prosthesis includes at least one imaging marker, receiving a cusp overlap viewing angle image and/or a coronary overlap viewing angle image of the transcatheter heart valve prosthesis within the native heart valve, determining, based on the cusp overlap viewing angle image and/or the coronary overlap viewing angle image and the at least one imaging marker, whether the transcatheter heart valve prosthesis is in a desired rotational orientation, if the at least one imaging marker in the cusp overlap viewing angle image and/or the coronary overlap viewing angle indicates that the transcatheter heart valve prosthesis is not in the desired rotational orientation, rotating the transcatheter heart valve prosthesis until the transcatheter heart valve prosthesis is in the desired rot

Abstract: Techniques for generating a canvass are disclosed. A canvass user interface is generated. This interface has a particular visual layout designed to enable efficient refinement of demographic data to identify targeted individuals and to facilitate canvassing events. Refining the demographic data enables a list of targeted individuals to be identified, where these targeted individuals are selected to be canvassed. Various canvassing tasks are generated for the canvass. An executable token is also generated. This token can be used to link a client device to a particular canvass associated with the executable token. Data is collected via the client device. That data is analyzed, and metrics associated with that data are displayed in the user interface.

Abstract: A software calibration strategy for calibrating solenoid controlled valves and valve systems in an automatic transmission. The strategy includes identifying a characteristic equation for the valve or valve system that is a mathematical relationship between a current applied to the solenoid and the pressure at the output of the valve or valve system. The valve or valve system is coupled to a test stand that depicts the operation of the valve or valve system in the transmission. Current signals are applied to the valve or valve system, and the output pressures are measured to determine coefficients in the equation using a curve fitting function. The coefficients are then stored in a control unit.

Abstract: An electrohydraulic transmission control apparatus (10) that produces, controls and directs hydraulic pressure inputs to the clutches, brakes and shift mechanisms of an automatic transmission to shift the transmission. A module body (14) supports control apparatus components and is removably mountable to a transmission housing (16) of the transmission. The module body (14) defines a plurality of fluid conduits (28). A plurality of control valves (26) is disposed on the module body (14) and meter hydraulic fluid through the conduits (28) to brake and clutch hydraulic cylinders and shift mechanisms in the transmission. A plurality of solenoid-operated control valves (26) is also disposed on the module body. A controller (34) disposed on the module body is connected to the solenoids (30) and controls the valves by operating the solenoids (30) in accordance with inputs received from sensors (36-44) that detect various factors representing the running state of the transmission and the vehicle it's mounted in.
