1 Introduction

Welcome to the Electronic Monitoring System and correctional
tool, created by Elmo-Tech Ltd., that has the ability to collect,
analyze, and intelligently act on information from multiple
sources.

An inconspicuous Transmitter (TX) is attached to the client's
ankle or wrist by means of a tamper-detecting strap. The
client's presence (or absence) is tracked constantly by radio
transmissions between the Transmitter and the MEMS3000
Receiver. When the client enters or leaves the defined home
environment, the MEMS3000 Receiver records the event. The
MEMS3000 Receiver then checks the client’s stored curfew
schedule to determine if the event is in violation of his or her
curfew order.

The MEMS3000 Receiver is a highly efficient monitoring unit,
integrating alcohol testing (BAT), video identity verification, and
radio frequency presence monitoring into a single unit. The
MEMS3000 Receiver transfers the breath alcohol test results and
client’s image to the monitoring center by means of cellular
communication (Data or GPRS).

The MEMS3000 Receiver reports certain violations to the
monitoring center as soon as they occur. Other violation and
non-violation events that are not defined as immediate are
stored in the MEMS3000 Receiver for the next upload. The
MEMS3000 Receiver initiates a pre-defined routine sanity call to
the monitoring center in order to report the status of the
equipment and upload stored events. This event information
completes the audit trail of the client’s behavior. The MEMS3000
Receiver detects and reports tilting, loss of power, loss of
cellular coverage, low battery, and other alarm conditions. The
MEMS3000 Receiver also detects Transmitter tampering,
removal, and low battery.
