  • Patent number: 10315032
    Abstract: Some embodiments include a system with a sensor with electrodes including an active electrode and a receiving electrode that is in physical contact with skin of a patient forming an electrical circuit with control electronics of a controller that can measure an electrical parameter using an active electrode and a receiving electrode within a closed loop electrical muscle stimulation system. A sense electrical pulse can be applied to the tissue using the sensor, an electrical parameter measured from the tissue, and a stimulation pulse applied to the tissue based at least in part on the measured electrical parameter. The stimulation is adjustably controlled by the controller to maintain a constant power output to the tissue based on the electrical parameter. A good is coupled to a computer readable medium configured to store usage data, the usage data relating to the patient's use of the good.

  • Patent number: 10268459
    Abstract: A computing device identifies and eliminates unneeded computations from an analytic computation. A symmetric matrix includes a row and a column for each of a set of partial derivative equations where each cell includes an indicator of whether or not a direct dependency exists and is updated to include an indicator of whether or not an indirect dependency exists. A solution row is identified from the symmetric matrix that includes a requested partial derivative. A cell is identified of the identified solution row that does not include the indicator that the direct or indirect dependency exists. The column is identified from the symmetric matrix that includes the identified cell. The partial derivative equation associated with the identified column is removed from the defined set of partial derivative equations to reduce a computer processing time to compute a derivative value for the requested partial derivative.

  • Publication number: 20180356733
    Abstract: An imaging apparatus for exposing a pattern onto a substrate has an illumination source that is energizable to generate a polarized exposure illumination beam of an actinic wavelength range and a mask disposed to impart the pattern to the polarized exposure illumination beam. A polarization beam splitter defines an illumination path that conveys the generated polarized exposure illumination beam through a quarter wave plate and plano-convex lens and toward a concave mirror and further conveys a reflected exposure illumination beam from the concave mirror toward an exposure plane for exposing the imparted pattern onto the substrate. The exposure plane is defined by the concave mirror, the plano convex lens, and the polarization beam splitter.

  • Patent number: 9740004
    Abstract: A volumetric imaging apparatus is energizable to form an image onto a display surface as an input to a monocentric catadioptric imaging apparatus having a light path for image-bearing light from the display surface, wherein the light path extends substantially symmetrically to a vertical plane that extends through a curved relay mirror and a curved primary mirror. The monocentric catadioptric imaging apparatus has reflective surfaces to fold the light path between the curved relay mirror and the curved primary mirror to condition the distribution of the image-bearing light in a horizontal direction. The light path of the monocentric catadioptric imaging apparatus directs light from the curved primary mirror toward a light input surface of a vertical pupil expander that has a light exit surface that is substantially orthogonal to the vertical plane. The light exit surface directs light through a free-form corrector for convergence and toward a windshield for display.
