  and technologies with respect to RFID
• Identify opportunities for RFID with event
  processing concepts
• Are sensor applications the next Event Processing
  sweet spot?

5
RFID Concepts (relevant to EP)

• Serialized identifier for assets
• Identifier structure (tag content)
• No line of sight requirement
• Filtering Collection
• Event Granularity
• Other types of Sensors and event input

6
Event Processing RFID Events

• Event Collection
• Raw Read
• Reader Controller/Management
• Capture Applications
• Correlate
• Retrieve and apply context
• To other events (same tag)
• To different asset class
• To other event streams
• React
• Event Report/Analysis
• Higher level business messages to application
  ecosystem
• Higher level event correlation
• Event Repository
• Archive/Consolidate
• Support track and trace with required level of
  detail

Use Case 1 Cold Chain Compliance in Supply Chain
10
Sample Business Cases

• Warehousing / Supply Chain / Transportation
• Creates a chain of custody to determine where in
  the cold chain a temperature breach has occurred
  if at all
• With integration, this solution can tell
  operators in real time, to accept, reject, or
  accelerate the product through the supply chain
  (dynamic queuingnot limited to FIFO or
  Expiration Date)
• Disaster Planning and Recovery
• Allows companies to understand the temperature
  changes in products when an anticipated power
  outage takes place. Executed at retail stores
  with a handheld and tags in the coolers /
  freezers.

11
Web Based Reporting (Secured)
12
Sample Business Case Benefits

• Accountability / Profitability
• Financial obligation for refused product is
  placed on the correct source in the chain of
  custody because there is a correlation between
  the cold chain breach and the time it took place
• Quality
• The shelf life of temperature sensitive products
  is impacted in a negative manner by variations in
  temperature.
• In understanding the impact temperature has on
  shelf life, the amount of time that the product
  was in an unacceptable temperature range must be
  known (degree minutes).

13
Sample Business Case Benefits, contd

• In-stock Position
• Cold chain breaches are identified immediately
  versus when the recipient opens the product and
  determines that it is unacceptable. That product
  must be immediately reordered and increases the
  safety stock levels.
• Food Safety Liability
• Microbial activity starts at an exponential rate
  at temperatures over 40F
• The consequences of infecting a customer with
  this type of illness are detrimental, not only
  from a financial sense but a companys reputation
  is tarnished.

14
Use Case 2 Asset Management (Hospital)
15
RFID Applications At Hospitals

• Patient Wristband
• Blood Product Management
• ER, OR, ICU Management
• Point of Care
• Pharmaceutical Pedigree
• Combating Counterfeit Drugs
• Asset Management

16
Why Asset Management?

• National average utilization of mobile equipment
  is 45 - Universal Hospital Services
• Hospitals can lose nearly 1 million a year in
  medical equipment thefts alone - HCPro Healthcare
  Marketplace
• Five to fifteen percent of hospital inventory is
  written off each year since it can no longer be
  located or more importantly serviced - Frost
  Sullivan
• Equipment moving from patient to patient without
  going through decontamination in between has
  become a significant issue to JCAHO in regard to
  infection control in hospitals - JCAHO Sentinel
  Alert
• To prevent infant mix-up
• To build an infrastructure

Use Case 3 People Tracking/Security
19
Losing a Child is a HUGE Problem

• Kids get lost everywhere amusement parks,
  shopping malls, stadiums, skiing areas, etc.
• Kids tend to wander away
• Kids are sometimes kidnapped
• If a child is missing, EVERY SECOND COUNTS

20
Solution Overview

• Enrich RFID data by doing a DB subquery
• Reader locations
• Family information
• Split the enriched stream into Parents and
  Children streams
• Join Parents and Children streams and select the
  pairs that are far apart

21
Location-based RFID Applications Lessons Learned

• Must analyze large volumes of data at high data
  rates
• Must provide real-time response
• Must enrich real-time data with reference data
  from databases
• Must provide functionality to make distance-based
  correlation easy

22
Summary
23
Common Themes for Sensors EP

• Interfacing with Real World
• Volumes, incomplete data, out of order
• Temporal Horizons
• Some short
• Some longer term
• Deriving Higher Level Events
• At different levels in the information chain
• Environments with Multiple Streams
• Event Processing Driving Process Management in
  Dynamic Environments

24
Goals

• Define use cases where event processing can be
  applied to RFID
• Identify weaknesses in event processing concepts
  and technologies with respect to RFID
• Identify opportunities for RFID with event
  processing concepts
• Are sensor applications the next Event Processing
  sweet spot?

25
Challenges for EP in RFID

• Cost
• Is there COTS opportunity?
• Its a hardware world
• Do enterprises realize that they have an event
  based problem?
• Implementing hierarchical filtering and
  correlation
