Abstract: Examples discussed herein relate to creating and handling lambdas in spreadsheet application, e.g., Microsoft Excel®. As discussed herein, lambdas are user defined functions (UDFs) that are natively creatable and maintainable through the use of a lambda registry in the spreadsheet application. In an implementation, a method of handling lambdas in a spreadsheet application is disclosed. The method includes detecting that a cell of a spreadsheet is populated with an expression that defines a lambda function and registering the lambda function with a lambda registry corresponding to the spreadsheet. The registration includes recording a home cell that identifies a location of the cell of the spreadsheet where the lambda function is defined. The method further includes replacing the expression that defines the lambda function with a reference to the registered lambda function.

Abstract: A method and apparatus for improving the optical properties of an LED using a retroreflector element. A light emitting apparatus includes a substrate, at least one light emitting device attached to the substrate and including an outer primary light emitting surface through which substantially all light is emitted, and a retroreflector assembly attached to the substrate. The retroreflector assembly includes a proximal surface adjacent to the substrate, a distal surface spaced away from the substrate, and a retroreflective portion arranged between proximal surface and the distal surface. A distance from the distal surface to the substrate is less than or equal to a distance from the outer primary light emitting surface to the substrate.

Abstract: Examples discussed herein relate to automatically creating lambda functions in spreadsheet applications, e.g., Microsoft Excel®. In an implementation, a method of automatically creating lambda functions in spreadsheet applications using a lambda shorthand notation is disclosed. The method includes analyzing contents of a cell of a spreadsheet to identify a formulaic expression and determining that the formulaic expression can define a body of a lambda function without using explicit lambda function notation or parameter declarations. The method further includes automatically creating and invoking the lambda function responsive to the determination. As discussed herein, creating the lambda function includes registering the lambda function in a lambda registry using the formulaic expression as the body of the lambda function that evaluates into an output value.

Abstract: Approaches herein provided surface mounted devices each configured as a stand-alone component suitable for attachment to a substrate such as a printed circuit board (PCB). In some embodiments, a method includes forming a base housing, coupling an electronic component to the base housing, and forming a cover over the electronic component, wherein the cover is coupled to the base housing. The electronic component may include a fusible link/element extending between terminals, the terminals wrapped around an exterior of base housing. The device may then be coupled to the PCB, for example, by attaching the terminals to an upper surface of the PCB.

Abstract: A lighting assembly having a plurality of light sources and a lens matrix having a plurality of lenses. The lens matrix may be positioned relative to the light sources so that each light source resides in a first orientation within one of the lenses and emits a light distribution. Relative translation between the light sources and the lens matrix alters the orientation of the light sources within the lenses, creating a different light distribution. A light source's orientation may change within the same lens, or the light source may translate to a different lens to alter the distribution of its emitted light.

In one embodiment the heat sink has a first portion having fins (that protrudes outside of the enclosure) and a second portion to house and mount the LEDs (that is positioned within the enclosure). Certain embodiments also provide for gaskets and other structure to prevent leakage between the heat sink and the enclosure, such that the light fixture is water-resistant.

Abstract: A quick analysis tool is configured to present one or more data analysis features that are tailored to the data in a selected portion of a spreadsheet document. The quick analysis tool may provide a quick analysis tool entry button, the selection of which causes a contextual user interface to be displayed. The contextual user interface facilitates a user to easily access one or more data analysis features. The quick analysis tool also provides a mechanism by which a user can preview and/or apply one or more of these data analysis features while bypassing the potentially steep learning curve and traditionally high barrier of entry for new or otherwise less advanced users of the spreadsheet application. Intermediate or otherwise more advanced users of the spreadsheet application will also benefit from the quick analysis tool because of improved efficiency for applying data analysis features to data within a spreadsheet document.
