For this program, Erallo developed a miniature wireless RF data transmission platform and integrated it with a wrist-worn, transdermal bio sensor. The mini-RF device was integrated in the housing of the “wristwatch” to collect the data points form the sensor on a continuous basis. The RF device stored and then automatically transmitted the data to a mini Base Station whenever it came into range. The Base Station was equipped with another RF device (to receive data from the wristwatch), an embedded processor (to store, timestamp and preprocess the data), and WAN connectivity to transmit the collected data points to a centralized clinic PC database via a phone line. This transmission was designed to send the data out to the clinic, on a nightly basis, without any human intervention.

We developed a GPS enabled RFID tag/patient sensor system for tracking trauma patients. The system uses a GPS-enabled RFID tag to identify and continuously track the location and timing of trauma patients/victims. The data is reported in real-time to a Trauma Center and integrated with the hospital’s central database. For this solution, Erallo developed a multi-frequency Base Station, mounted inside an ambulance. To provide flexibility and full coverage , the Base Station was built to transmit and receive in multiple frequencies . It was comprised of an 2.4 GHz RF unit, a cellular interface (Lucent’s EVDO), and a GPS connection. An RF device was integrated with the Base Station to provided local connectivity to the integrated e-TAG RF device and the EMT’s PDA. The Base Station was also connected to the GPS unit inside of the ambulance. The ambulance mounted GPS antenna received the GPS location coordinates of the ambulance. The GPS location coordinates were then relayed, via the cellular interface of the Base Station, to the Central Monitoring Station at the Trauma Center. The system was developed for the Army to track and monitor wounded soldiers. Erallo, in collaboration with a local sensor company and a leading BMC Surgeon, developed the system, which is being upgraded to operate in situations of mass casualties.
Automated Vehicle Locator System (EralloAVL) The Erallo Automated Vehicle Locator (AVL) system is a hardware, software and networking system that tracks the location of “tagged” vehicles or buses within a network. The real-time tracking, movement and location of the buses is overlaid onto a zoomable map and displayed onto a web-based PC screen for monitoring. Each tagged vehicle is equipped with the EralloAVL Transponder, which is responsible for transmitting its location and identification. Two modes are possible with the EralloAVL: 1) a GPS-assisted location tracking mode, and 2) a non-GPS location tracking mode. The two main devices of the AVL system, an active transponder and a GPS component, are packaged together in the EralloTRAN. Each vehicle in the monitored network will have an EralloTRAN installed in it. The GPS component is a low power, small footprint GPS unit, with an active, highly tuned antenna to continuously obtain the location of the vehicle by the GPS satellite. The active transponder component is a wireless, multi-frequency RF communication and monitoring device that picks up and automatically responds to incoming coded signals. The transponder uses its CPU and memory to control the integrated GPS device and the two-way communication between the vehicle and the monitoring station. The EralloTRAN will perform the tasks of system control, data collection, data processing and data analysis. It’s also responsible for scheduling and transmitting wireless communications and data (as well as location tracking in the GPS-free version). A display unit and key pad can be integrated in the vehicle to enable two-way wireless message communications. Other services, like voice enabled notifications and guidance for handicapped and ADA requirements, can be superimposed onto the RF infrastructure to provide enhanced features. The EralloAVL Command Center software is web and GUI enabled so that users can easily monitor the locations of vehicles and easily control the system. It displays a map of the streets, routes and stops. When the system is turned on, it searches for vehicles equipped with the EralloTRAN and then establishes a link between the Command Center and the buses. This link is used to poll for the location and speed of the vehicle. The position of each vehicle is displayed on the map and its location updated.
PDA-based Data Collection with Automated Connectivity Erallo is developing WinCE.NET based software to run on PDAs for users to record and monitor their food intake. The system calculates and tallies the calorie, protein, fat consumption and other nutrients continuously throughout the day. The food intake report is then transmitted daily to a mini Base Station for temporary storage. Then on a nightly basis, the report is automatically transmitted to a research center for analysis. This software also provides a mechanism for researchers to automatically send daily feedback to the users. The database of the system is based on the USDA FDA Food database. A prototype of this system was developed in conjunction with nutritionist and scientific researchers and is under review. Version 2 of the system is currently under development. The System is designed with intuitive and easy-to-use graphical user interfaces (GUIs) on the PDA screen to make recording of food simple. Users are able to select food items by groups or a quick search feature, and they can alter the units and quantity of any foods they select/eat. They’re able to save their favorite foods as well as automatically saving all recently eaten foods. Researchers are able to view a complete picture of their subject’s diet on a daily basis. They can also provide feedback to the users in reports that are automatically displayed on the user’s PDA. The daily logs of the user’s diet and associated nutrients are exported in an industry standard XML file and transmitted to the researcher’s database for automated integration into their database.
GPS-free Wireless Locator and MobileTag The Wireless Locator Systems use RF and ultra-sound detection units to determine the location and movement of people in a building or structure, in real-time. The systems use mesh networking to detect movement/location for areas where GPS signals cannot reach. The PassiveRF systems are applicable for monitoring security zones and identifying breaches, including the movements of people, packages, luggage, equipment and inventory. The 433 MHz ActiveRF systems are applicable for the continuous and real-time tracking and monitoring of movement. It provides movement direction, acceleration and history. Pre-engineered solutions come with both active RF tags and passive RF tags. The passive RF tags are economical to implement but have a limited range. The system was designed for security, urban combat training applications, and monitoring of inmates under suicide watch in correctional institutions. It is also applicable to security zone-based tracking solutions (of vehicles and people) and remote tracking of movement.
Wireless automatic identification and tracking requires effective sensing, communications and networking – but with the right design and devices – you can have a powerful tool for asset security, mobile equipment tracking, supply chain inventory and personnel ID in secured areas. Erallo uses state-of-the-art electronics and MEMs based components to make our RFID readers small and lightweight. And our tags are bi-directional able to be operate in a network. Whether for inventory control and network based tracking applications, these features provide for convenient, flexible and powerful solutions. The bi-directional and wireless features means that items can be automatically scanned when the reader comes within range – eliminating the need for individual scanning of each item! Adding sensing elements to the tags enables environmental monitoring for even more observation and control. Erallo’s RFID bi-directional and networked readers and tags provide for successful solutions to:

For this government customer, Erallo is developing a wireless network system using RF transceiver devices, 802.11/WiFi technology, MEMS-based miniaturized Base Stations, and PDA display units. Our partner company is developing the ethanol sensors which will be deployed in the car and as a wrist-worn sensor. Integrated RF devices will transmit the collected ethanol (alcohol) data to the mobile Base Station in the trunk of the vehicle. The trunk-mounted Base Station processes the collected data and then, when in comes in range of a police check point with an enabled PDA, it automatically transmits the data (alcohol levels, driver, vehicle, priors) to that PDA to alert the Officers of an approaching offender. The system is being developed as an effective, low cost, wireless sensor system for monitoring/catching repeat DWI drivers at Police Check Points.
