Abstract: A pedestrian alert system supported on a mobile device such as a smartphone, tablet computer, or a wearable computing device which is employed by a user to engage in various activities, is configured to provide visual, auditory, or haptic alerts when the system uses location sensing and map data to determine the user's proximity to a pedestrian street crossing. The alert attracts the user's attention by having the user perform an explicit action to dismiss the alert before being able to continue with the activities on the device. Operations are suspended for applications rendering content on the device display (e.g., a touch screen), user inputs are disabled, and the display may be blurred, dimmed, obscured, or otherwise deactivated. The pedestrian alert system can take a snapshot of application state prior to suspension so that the applications can gracefully resume operations without disruption once the alert is manually or automatically dismissed.

Abstract: Methods, systems, and devices are described herein for estimating a three dimensional (3D) print-time for generating a 3D object relative to one or more 3D model or printer parameters. In one aspect, at least one 3D model or printer parameter may be received for generating a 3D object by a 3D printer. Historical print-time data associated with at least one 3D model or printer parameter for generating other 3D objects may be obtained. Based on the received 3D model and printer parameters and the obtained historical print-time data, an estimated print-time for generating the 3D object by the 3D printer may be determined before slicing the 3D model by the 3D printer. In another aspect, a desired print-time for generating a 3D object may be received. One or more 3D model/print parameters may then be configured to achieve or exceed the desired print-time.

Abstract: A set of conversations taking place by users within a geographic location are identified. Keywords for a conversation under analysis, in that geographic location, are identified based on a frequency with which terms are used in the conversation under analysis and in the related conversations. The keywords are automatically added as searchable terms corresponding to the conversation under analysis, and a communication system is controlled to notify client components of the keywords.

Abstract: Mobile localization of communications allows users to communicate anonymously with other users who share a location that is mobile. The systems and methods provided herein distinguish users who are co-mobile from users who are merely co-located to enable mobile conversations to travel with co-mobile users without a dedicated communications connection being established beforehand between the users. The conversations travel with the co-mobile users and are not tied to a physical location, allowing for localized and anonymous communications for user who are travelling together.

Abstract: Techniques described herein provide enhanced management of passwords for applications and services. Generally described, the techniques disclosed herein leverage the strength of existing security measures built into operating systems to generate and communicate encrypted passwords to enable components of a computing system to operate with a heightened level of security. In some configurations, the encryption of a password using strong keys that are associated with an identity improve the security of a computing device as well as improve the security, processing, and communication of secured documents and printing schemas. In some configurations, passwords for accessing documents are encrypted and embedded in printing schemas. The encrypted password is communicated between modules of an operating system in a process for generating PDF files having improved security. The claimed techniques also leverage components of existing systems without the requirement of additional libraries.
