EPE Minder
Approx construction cost US$29 (Transmitter) and US$45 (Receiver)
Looks after your personal belongings – maybe even your children! The EPE Minder consists of two type-approved transmitter units and a receiver. If either transmitter becomes separated from the receiver, a buzzer in the latter part will sound. The receiver is fitted with a switch to allow the use of only one transmitter if required. This system was originally designed as a two-channel child alarm (to protect either a single child or two children at the same time) but many other applications spring to mind. For example, one transmitter could be placed inside a briefcase and another in a coat pocket. If the user forgot to pick up either of these items and walked away, the buzzer would sound in the receiver. The EPE Minder uses a system of digitally encoded low-power radio signals, which pass from the transmitters to the receiver. The code is different for each transmitter so that the receiver is able to distinguish one from the other. The operating range may be adjusted according to the intended purpose. The range of the prototype exceeded 12 meters in open air. It will also work throughout several rooms indoors if required.
