Agriculture Problem: Pistachios must go from tree to huller

quickly to maximize qualityUse PDAs to scan barcodes on individual bins and to update data records

Problem: In managing artificial insemination of cattle, it’s essential to know where samples come from

Record activities on a custom mobile application, rather than on paper forms (save 25% on data management costs)

Education Problem: School administrators need access to

student information outside of the office and classroom (e.g., roaming the halls or at events)

Mobile access to schedules, contact and medical information

Problem: Laptop PCs take up too much space in lab and create a barrier between teachers and students in the classroom

PDAs with special sensors as lab tools and data recordsInteractive surveys in the classroom

Law Enforcement Problem: It’s inefficient for police officers to

conduct vehicle and person checks over walkie-talkies

Allow queries from mobile devices

Problem: Analysis of potential racial profiling requires specific data about police encounters

Give officers a questionnaire to fill out every time they make a stop

Health Care Problem: Paper medical records are difficult to

manage and maintainProvide mobile devices for the electronic dictation and review of medical records

Problem: Thousands of deaths each year are caused by administration of the wrong medication

Scan medication upon administration and electronically for a valid physician order

Real Estate Problem: Real estate agents are frequently

showing property to clients and need to access information back at the office

Provide mobile access to property and customer profile information

Transportation Problem: Truckers need up-to-date information

about pickup and delivery destinations, especially with increasingly real-time shipping needs

Combine GPS tracking and navigation with automated dispatching

Problem: Dispatching taxi cabs to the closest customers is a difficult process

Use GPS-enabled mobile devices to track and send jobs to a fleet of taxis
