Abstract: Mentally challenged persons such as autistic children and Alzheimer's patients can become lost and they are hard to find because they have difficulty communicating or they are confused and disoriented. The present invention provides an apparatus, system and methods for locating lost persons (or animals or packages) whether they are indoors or outdoors. The apparatus comprises a cellular telephone unit which can be activated by a RF signal and which a child or patient can wear. The wearable unit can be activated by a caregiver's smart phone having a locating application installed therein. The locating application enables the caregiver to locate the lost person using radio direction finder triangulation when the lost person is within a few hundred feet of the caregiver. When the lost person is further away, the locating application employs cell phone tower triangulation or the wearable unit GPS/Assisted GPS application to determine an approximate location of the lost person.

Abstract: A substantially uninterruptible backup power system to provide power to common household appliances comprises a rechargeable battery, a trickle-charging circuit to keep the battery fully charged at all times from the receptacle power, a DC to AC inverter to supply standard AC line voltage from the battery to the lamp, a relay switch, controlled by main power voltage, to switch to the backup system when main power fails, and a timing circuit to optimize a voltage output of the system based on current battery voltage and a desired time period for the voltage output. The system can be set to operate only when the appliance is turned on, which optimizes the current and power required to provide backup power to the appliance for a maximum period of time.
