Abstract: Real-time busyness information is for a public place is computed in a privacy-sensitive way, and provided for display in relation to historical busyness information. An aggregate amount of real-time location information available for a particular public place is measured (410), and used to determine (420) whether the public place is privacy-qualified. If the public place is privacy-qualified, real-time busyness information is computed (440) for the public place based on the real-time location information. Further, it is determined (450) whether the computed real-time busyness information is accuracy-qualified, based on a comparison of the real-time busyness information to historical busyness information. If both qualifications are met, the real-time busyness information is output (470) for display or to another application.

Abstract: A photosensitizer formulation can be disposed on or in a mesh; net; netting; screen; curtain of strands, fibers, or monofilaments; substrate, personal protective gear, mask, or any other suitable object. The photosensitizer formulation, when in contact with molecular oxygen and activated by light or ultrasound, produces microbicidal singlet oxygen. A variety of different arrangements and applications are described. For example, an air flow device may also be included to generate a flow of air through or over the photosensitizer formulation. A fluorescent formulation may be included to monitor photobleaching. The photosensitizer formulation may be disposed in a concentration gradient to generate antigenic particles by damaging or destroying microbes.

Abstract: Methods, systems, computer-readable media, and apparatuses for providing schema definition generation and management to enable a relational query tool to access data in a non-relational database. The schema definition tool may sample a non-relational database to produce a sample set of a table of the non-relational database and may generate multiple linked virtual tables to represent arrays in the sample set as scalar values. The schema definition tool may then automatically generate a table definition for each real and virtual table of the non-relational database to produce a schema definition representing the structure of the non-relational database. A relational query tool may now use the schema definition to format relational queries or commands to access data residing in the non-relational database.
