LPD LOCATING PERIMETER DEVICE

摘要

The Locating Perimeter device consists of two separate units; one is a receiver and the other is a transmitter. The transmitter consists of a sound producer that features programmable sounds such as beep tunes, recorded voices or voice transmission. When the receiving unit is beyond a certain prescribed distance, the transmitter sounds an alarm to alert that the receiving unit is outside the prescribed or desired perimeter. For these purposes, alarm means preprogrammed or programmable sounds, including but not limited to beep tunes, recorded voice or voice transmission. The transmitting unit has a battery, loudspeaker, a circuit board, a microphone, a low battery indicator and a low frequency transmitter. The receiving unit has a low frequency receiver, a circuit board and a battery. Both transmitting and receiving units can accommodate a speaker to allow voice communication between them. The device allows people to keep track of loved ones, children, patients and/or pets. The device can be attached to collars or made as collars for pets such as dogs and cats. The device is also suitable for people suffering from Alzheimer's disease or Mental Dementia (MD). Specifically, the device can help care providers, in institutional or home environments, keep track of Alzheimer's or MD patients should they wonder beyond a required distance. The device can also help parents and guardians keep track of children at parks, theme parks, shopping malls, nurseries or places where a child or children are required to be within a desired perimeter. Notwithstanding the foregoing uses, the device can be used for other tracking and monitoring purposes and can be modified to accommodate different ranges.
