Passive Tamper-Resistant Seal And Applications Therefor
US Patent #10,008,083 (Continuation in Part #3 of US Patent #8,063,779)

Defines systems and methods of using a ribbon array of passive Radio Frequency Identification (pRFID) tags to provide alerts and information about the severity of materials fractures at locations prone to fatigue. This CIP further expands the technology of a ribbon array of multiple pRFID seals on a substrate with different RFID seals detuning in response to differing tensile loads with the addition of at lease one surface acoustic wave (SAW) radio frequency identification (RFID) seal to further expand fatigue fracture detection capabilities.

Method and Apparatus for Cataloguing and Polling Movement in an Environment for Purposes of Tracking and/or Containment of Infectious Diseases
US Patent #7,817,046; Canada Patent #2597224

A system for containing and restricting the spread of infectious diseases within hospitals, clinics and other medical facilities by cataloguing and delimiting movement of patients, medical staff, employees, visitors, contractors and other personnel attending or on-site. The system also provides for tracking and cataloguing contaminated medical apparatus, medicine trolleys, food trolleys, medical gas stations, laundry baskets and other mobile or movable medical equipment or facility equipment to prevent spread of the infectious disease or viral entities.

System and Method for Tracking Inventory
US Patent #8,145,546; United Kingdom Patent #GB2402242

An inventory tracking system that utilizes Radio Frequency Identification (RFID) tags to track the inventory of items in a specified location such as storage cabinets, refrigerators/freezers, dispensing machines, stock rooms, warehouses, etc. A card/wristband/fob reader can be utilized to monitor, record and/or restrict the removal of items from each location.

Supplementary Antenna for RFID and Product Unit Incorporating Same
US Patent #7,559,482

Applicable to inventory management for vending/dispensing machines, fridges/freezers, etc, or any “smart shelf” based solutions to simplify the complexity and boost the efficiency of RFID antenna systems. Supplementary Antenna for RFID is specifically tailored to enhance the reading capabilities of RFID tags placed on/in products, packages, etc. especially in previously difficult to read types of conditions.

Communication Server Including Virtual Gateway to Perform Protocol Conversion and Communication System Incorporating Same
US Patent #6,873,620; Canada Patent #2281752; Europe Patent #EP0972380
Claim charts available   LINK to Litigation Listing

Intelligent Communications Server enhances communications connectivity in wireless and/or land-line networks for seamless interconnectivity of incompatible communication systems with automatic protocol detection and conversion, which enables the significant reduction of cellular network signaling loads as well as wireless device power consumption for IoT (Internet of Things) and OTT (Over-the-Top) media.

Physical devices connected to separate networks can communicate using different protocols through cStar’s Intelligent Communication Server, which acts as an intermediary between the networks and performs protocol conversion so that messages are automatically converted into a protocol compatible with the communications network where the message is being sent.

Wireless Transport Protocol (“WTP”)
US Patent #6,563,813
Claim charts available   LINK to Litigation Listing

cStar’s flagship patent which enables the significant reduction of cellular network signaling loads as well as wireless device power consumption for IoT (Internet of Things) and OTT (Over-the-Top) media, WTP reduces the number and size of radio packet transmissions over any wireless network by using packet reduction and special data compression technology. WTP also improves reliability by applying a retransmission algorithm that avoids/eliminates packet loss.

WTP is a Connectionless protocol that provides:

• Guaranteed packet delivery
• Packet number reduction
• Packet compression
• Packet integrity and security
• Highly efficient error detection and correction

This fundamental patent protects cStar’s SkyGate^®, DirectGate^®, and Virtual Gateway engine compression and encryption technologies.

Cashierless Shopping Store and Components for Use Therein
US Patent #6,725,206; Canada Patent #2201423

One-stop, self-checkout shopping carts. A Cashierless Shopping Store includes a variety of intelligent shopping carts into which shoppers place selected products for purchase. Each of the carts contains a portable wireless terminal to read barcodes of items placed in the cart for purchase and a weight detector (load cell) for the terminal to audit the weight of products placed in the cart. At the checkout station, a precise scale makes a final tally and wirelessly reconciles the collected shopping contents through a local area network. If the correlation is precise, payment is processed via a credit or debit card transaction.

Radio Range Finder
US Patent #5,805,105; Canada Patent #2190940; New Zealand Patent #287000

Radio Range Finder is a radio range finding technology that includes a range finder and a variety of remote mobile transponders. The range finder transmits a signal modulated with an address code that represents a particular mobile transponder ID. When the mobile transponder receives the modulated signal [M2], the mobile transponder transmits a return signal [Rs] to the range finder, which conveys the signal to a mixer. The output of the mixer is then filtered and demodulated to produce an output signal proportional to the distance between the mobile transponder and the range finder.

Proximity Detector
US Patent #5,952,835

A non-contact capacitive adjustable detector that is used to detect the presence or removal of an object within a predetermined perimeter to the detector.
