Publication number: 20240095645Abstract: A method of generating customizable goal representation is disclosed. A request from a user to view a goal representation is received. A flexible goal ontology is accessed that comprises one or more goal entities, one or more goal relationships between the goal entities, or one or more goal properties, the one or more goal properties including one or more metadata attributes relating to the one or more goal entities. A set of mapping rules is obtained that defines mappings between one or more goals. The set of mapping rules is evaluated to assemble a customized goal representation tailored to the user. The customized goal representation is updated based on a revaluation of the mapping rules affected by changes to the one or more goal entities, the one or more goal relationships, or the one or more properties.Type: ApplicationFiled: September 21, 2023Publication date: March 21, 2024Inventors: Sven Martin Andreas Elfgren, Friedrich I.

Publication number: 20240095680Abstract: A method of implementing administrative services for a compensation platform is disclosed. One or more interactive compensation representation views are generated based on an evaluation of mapping rules against a flexible ontology and current data state, the flexible ontology comprising customizable compensation components, relationships, and properties. One or more compensation representation views are dynamically updated in real-time in response to changes in compensation data, user context, or access permissions without requiring manual regeneration of the one or more compensation representations.

Patent number: 9766464Abstract: In a near-eye or heads-up display system including a display engine and an optical waveguide, a quarter-wave retarder (QWR) is positioned between a polarizing beam splitter (PBS) of the display engine and an input diffraction grating of the waveguide. Additionally, a linear polarizer can be positioned between the PBS and the QWR. Light corresponding to an image generated by a reflective microdisplay of the display engine is diffracted into the waveguide by the input diffraction grating, so it can travel by way of total internal reflection to an output coupler and viewed by a human eye. The QWR alone, or in combination with the linear polarizer, prevents a ghost image that may otherwise occur if a portion of the light corresponding to the image, that is diffracted into the waveguide by the input diffraction grating, is diffractively out-coupled by the input diffraction grating and thereafter reflects off the reflective microdisplay.Type: GrantFiled: December 17, 2015Date of Patent: September 19, 2017Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Yarn Chee Poon, Ian Nguyen, Eliezer Glik, Tapani Levola

Patent number: 9494799Abstract: A transparent waveguide, for use in tracking an eye illuminated by infrared light, includes an input-coupler and an output-coupler. The input-coupler includes a stack of electronically switchable diffractive gratings arranged parallel to one another, each of which has a respective lens power that causes each of the gratings in the stack to have a different focal length. Each grating, when turned on, couples received infrared light into the waveguide. A sensor images an eye in dependence on infrared light beams that exit the waveguide at the output-coupler. Images of an eye, obtained using the sensor, are analyzed to determine which one of the electronically switchable diffractive gratings, when turned on, provides a best focused image of the eye or portion thereof. The one of the electronically switchable diffractive gratings, which provides the best focused image of the eye, is used for imaging the eye during eye tracking.Type: GrantFiled: September 24, 2014Date of Patent: November 15, 2016Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Steven Robbins, Ian A.

Patent number: 9377623Abstract: A transparent waveguide, which is for use in tracking an eye that is illuminated by infrared light having an infrared wavelength, includes a volume Bragg grating type of input-coupler adapted to receive infrared light having the infrared wavelength and couple the received infrared light into the waveguide. The volume Bragg grating includes a lower boundary and an upper boundary that is closer to the output-coupler than the lower boundary. A k-vector angle of the volume Bragg grating at the lower boundary is greater than a k-vector angle at the upper boundary, with k-vector angles of the volume Bragg grating between the lower and upper boundaries gradually decreasing as distances decrease between grating planes of the volume Bragg grating and the upper boundary. Additionally, the volume Bragg grating preferably has an angular bandwidth that is no greater than 5 degrees.Type: GrantFiled: August 11, 2014Date of Patent: June 28, 2016Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Steven Robbins, Ian A.

Publication number: 20160077338Abstract: The technology provides a waveguide display having a compact projection light engine and a diffractive waveguide. The diffractive waveguide includes input diffraction gratings with rolled k-vectors. The projection light engine provides collimating light to a projected exit pupil external to the diffractive waveguide. The projection light engine components may include a light (or illuminating) source, microdisplay, lenticular screen, doublet, polarizing beam splitter (PBS), clean-up polarizer, fold mirror, curved reflector and quarter waveplate. A method of manufacturing a diffractive waveguide includes providing input gratings with rolled k-vectors. Rays of light are diffracted by, and passed through, a master hologram to form input diffraction gratings of a copy substrate. A second copy substrate may likewise be formed with a different master hologram.Type: ApplicationFiled: September 16, 2014Publication date: March 17, 2016Inventors: Steven John Robbins, Ian Nguyen

Patent number: 9164290Abstract: Grating configurations are described for creating time sequenced field of view (FOV) tiles for a waveguide display. Pairings of non-output diffraction gratings and output diffraction gratings are activated to create a number of FOV tiles in a time sequence, for example in a frame update period for the image. Examples of a non-output grating are an input grating and a fold grating. For a set of at least three gratings used to make the pairings, each non-output grating is paired with each output grating. The number of pairings, and so the number of FOV tiles, is equal to a product of the total number of non-output gratings and the total number of output gratings. At least one diffraction grating in the pairing is an active pairing. Also described is a multiplexed diffraction grating including multiplexed K-vectors which increases the overall angular bandwidth for both incidence and diffraction.Type: GrantFiled: November 6, 2013Date of Patent: October 20, 2015Assignee: MICROSOFT CORPORATIONInventors: Steve J.
