Patent number: 7796054Abstract: A computer implemented function monitors the position of the magneto switch in an aircraft to provide real-time feedback of engine RPM drop during a magneto (mag) check and communicates whether parameters are within limits. The function can also monitor engine and groundspeed/airspeed data in an aircraft to verify the magneto switch is in the correct position during engine start, takeoff and flight and can provide an alert to the pilot if the switch is not in the correct position. The automated magneto check function provides an easy way to test the operation of the aircraft's engine-driven magnetos and provides additional safety by alerting the pilot to unsafe positioning of the switch.Type: GrantFiled: October 19, 2007Date of Patent: September 14, 2010Assignee: Vertical Power, Inc.Inventors: Marc Ausman, Kevin DeVries

Patent number: 7725144Abstract: A method of determining disease state in an individual. A portion of the tissue of the individual is illuminated with excitation light, then light emitted by the tissue due to Raman scattering of a chemical with the tissue responsive to the excitation light is detected. The detected light can be combined with a model relating Raman emission with disease state to determine a disease state of the individual. The invention can comprise single wavelength excitation light, scanning of excitation light (illuminating the tissue at a plurality of wavelengths), detection at a single wavelength, scanning of detection wavelengths (detecting emitted light at a plurality of wavelengths), and combinations thereof. The invention also can comprise correction techniques that reduce determination errors due to detection of light other than that from Raman emission of a chemical in the tissue. For example, the reflectance of the tissue can lead to errors if appropriate correction is not employed.Type: GrantFiled: December 19, 2003Date of Patent: May 25, 2010Assignee: VeraLight, Inc.Inventors: Marwood Neal Ediger, Craig M.

Patent number: 7388669Abstract: The present invention provides methods for generating interferometric information. Interferometric information from refractively scanned interferometers can contain errors due to wavelength-dependent refractive indices. The wavelength-dependent refractive indices of elements of the interferometer can produce errors when the OPD at a reference wavelength is different than the OPD at a sample wavelength. The invention can provide correction of interferometric information using relationships between the OPD at the wavelengths of interest, which correction can also be dependent on physical relationships among elements of the interferometer.Type: GrantFiled: August 15, 2005Date of Patent: June 17, 2008Assignee: InLight Solutions, Inc.Inventor: Russell E.

Patent number: 7379048Abstract: The present invention provides a method of human-computer interfacing that provides efficient implementation of intuitive controls in a three-dimensional space. The method comprises providing a three-dimensional space, characterized by x and y dimensions, together defining a plane approximately orthogonal to the user's direction of view into the space. A z dimension, approximately parallel to the direction of view, further characterizes the three-dimensional space. Objects in the space can be defined by x, y, and z coordinate sets. A control is provided having x and y coordinate sets as any other object. The z coordinate set of the control, however, spans a range of values, giving the control an increased depth. The control's range of z can be infinite, making the control accessible at all depths, or can be a finite range, making the control accessible only from that range of depths. Movement of a cursor into the region corresponding to the control initiates interaction with the user according to the control.Type: GrantFiled: April 22, 2004Date of Patent: May 27, 2008Assignee: Novint Technologies, Inc.Inventor: Thomas G. Anderson

Patent number: 7331034Abstract: A tool for distributed software development maintains a pool of software modules. A module manager manages submissions to and downloads from the pool. The module manager can be a computer system with programming and resources suited for managing the pool. Developers and users can access the module manager via a computer network such as the internet, or via other transmission mechanisms. A developer intending to submit a module to the pool can specify access conditions associated with the module, and transmit information needed to access the module. The module manager can add the access information and access conditions to the pool. A developer or user intending to access a module from the pool can identify a desired module. The module manager can then determine if the intended access complies with the access conditions associated with the desired module. If it does, then the module manager can transmit the access information.Type: GrantFiled: January 9, 2001Date of Patent: February 12, 2008Inventor: Thomas G. Anderson

Patent number: 7225115Abstract: The present invention provides a method of generating haptic interface experiences that is capable of generating haptic companions to existing two-dimensional images. The method exploits the dominance of visual over haptic in humans: human tactile, proprioceptive, and kinesthetic senses do not supply as much fine detail as human vision, and consequently haptic representations do not have to be as detailed as the corresponding visual images to be believable to a human user. An existing two-dimensional image can be used as the visual component of a human-computer interface. A three-dimensional haptic model that is topologically similar to the image can be selected, where topological similarity means that the haptic model provides an acceptable approximation to important characteristics of the haptic experience desired to accompany the two-dimensional image.Type: GrantFiled: October 4, 2001Date of Patent: May 29, 2007Assignee: Novint Technologies, Inc.Inventor: Jake S. Jones

Patent number: 7220051Abstract: A switch, such as an electromechanical or optical switch, whose state is responsive to temperature history, for example temperature excursions above or below a critical temperature. An element of the sensor made from shape memory alloy changes shape when exposed, even temporarily, to temperatures above the Austenitic start temperature As or below the Martensite start temperature Ms of the shape memory alloy sensor element. The shape change of the SMA element causes the sensor to change between two readily distinguishable states. The sensor can include a one-way stop element that creates a persistent indication of the temperature history. The switch also has built-in stops allowing the sensor to be manufactured and stored at temperatures above the Austenitic temperature without causing the indication of an over-temperature event, before the actual use.Type: GrantFiled: December 27, 2004Date of Patent: May 22, 2007Inventor: Mohsen Shahinpoor
