Abstract: The disclosure herein describes an emotional insight management system that provides user-configured prompts and insights to the user. In some examples, an insights application provides personalized, recurring prompts to encourage users to provide current emotional state updates to a well-being journal. The user's responses over time are aggregated within a historical trends report, which provides emotional response data over time. The insights application generates insights into potential reasons for the user's emotional states on a given day. The system analyzes the user-provided emotion response data with integrated work-related data to identify reasons for the user's mood and make recommendations for actions to be taken by users to reduce stress and improve the user's emotional well-being.

Abstract: A method and apparatus for quick, safe, and easy installation of electrical fixtures in the building construction field, including connecting the fixture to a mounting mechanism for structural support and electrical service. A coupling mechanism is attached to or incorporated into the fixture. The coupling mechanism has built-in electrical leads that are designed to connect with the electrical leads on a fixture-facing interface of the mounting mechanism.

Abstract: System and method for fuel-cell and motor trend monitoring including recording signals from fuel-cell and motor system-condition sensors or sets of onboard sensors and periodically analyzing results to examine fuel-cell and motor system performance trends to predict the need for fuel-cell or motor system maintenance. Various analyses can be performed, separately or in parallel, including: comparing the current parameter values with recorded parameter values in previous instances of similar operating conditions; comparing parameter values to predetermined nominal ranges; and detecting sensed parameter values that exceed recommended fuel-cell or motor system operating conditions or that exhibit trends over time that if continued result in exceeding fuel-cell or motor system operating conditions or producing out-of-bound readings.

Abstract: A virtual enigma cipher system is described herein that allows for symmetric encryption and decryption of data. During encryption, a plurality of wheels representing sequences of data are used to encrypt a message. The plurality of wheels includes at least one dynamic wheel, which is generated based on a password, and a plurality of static wheels. During encryption, the unencrypted message is iterated from beginning to end. During each step of iteration, the encrypted payload value for a particular position is determined by performing an exclusive or (XOR) operation between the value of the unencrypted message at the position, and the values of the wheels at their respective wheel pointer positions. The particular position is then incremented, as are the wheel pointer positions, and iteration continues until the entire unencrypted message has been encrypted as part of the encrypted payload. Padding data and the message length are appended to the encrypted payload. During decryption, the steps are reversed.

Abstract: Freeform input is not native to several application or document types, but is desired by users as an input mode, especially for collaboration. Systems and methods are therefore provided to enable the insertion of an electronic collaboration workspace that accepts and stores freeform input for use as an object embeddable in various documents. An external host application provides the functionalities needed for freeform input, and the inputs may be committed to the document or stored as a separate document which may be referenced and accessed by multiple users for purposes of collaboration.
