Deconstructing and rendering of web page into native application experience
A lack of available responsive options for existing web sites and/or pages, and the wide spectrum under which they fall presents a challenge for a satisfying mobile user experience (UX) with a hosted collaboration service. Templates used to create a site and/or page may each have capabilities and features which “cross-over” into other templates. Deconstructing and rendering a web page into a native application experience at a mobile client may highlight a template's functionality to enhance the UX. For example, a server side application programming interface (API) may be provided for the mobile UX, a type of a page to be rendered may be determined, the page may be deconstructed into pieces, and the deconstructed pieces may be provided to rebuild the page at the mobile client natively. The page may be rendered on the mobile client with added elements based on the deconstructed pieces to enhance the mobile UX. |

Consolidating information from different signals into an event
The present invention extends to methods, systems, and computer program products for consolidating information from different signals into an event. Aspects of the invention used a multiphase approach to consolidating information from different signals into (e.g., deduplicating) an event. Detected events are held in the event holding cache for some amount of time after detection in accordance event holding criteria. As events are detected, an information consolidator compares currently detected events to previously cached events. Events determined to be the same event are grouped into an event group. When holding criteria expire for an event in the event group, the event group is published to one or more entities. As such, each new detection of the event does not trigger a corresponding new notification. Different portions of content from the same signal can also be monitored to reduce duplicate detections based on different content types in the same signal. |

In addition, the command module, in response to the message not being the discovery message and not being the initial message, determines whether the message comprises a valid safety command. In response to the message including a valid safety command, the command module enters the run mode. |

Hinge assembly with slow close and optional slow open characteristics
An appliance hinge assembly includes an arm to mate with a receiver. A door mounting lever is adapted to be connected to an appliance door, and the lever includes an inner end pivotally connected to the arm. The lever pivots relative to the arm between a first position and a second position, through an intermediate position. A slide link is located adjacent the lever. The slide link inner end is pivotally connected to the arm at a location that is offset from the main pivot axis such that pivoting movement of the lever results in movement of the slide link relative to the lever. A biasing system includes a spring that urges the lever toward the first position. A damper system includes a damper that damps movement of the lever. Alternatively, the arm connects to the appliance door and the lever connects to the appliance body. |
