Abstract: A light sequencer for a toy having a simple way for individually varying the on and off times of each stage of a chain or ring. Each stage has a light controlling amplifier/switch whose gain is individually controlled by a hysteresis element. When the voltage across the hysteresis element is below its set breakdown voltage, it non-conducts, thereby causing the amplifier/switch to have negative gain, and the controlled light is not lit. When the voltage across a hysteresis element equals or exceeds its set breakdown voltage, it `fires` into a highly-conductive state, causing the amplifier/switch to have very high gain, and the controlled light is lit. The hysteresis element remains in its conductive state until the voltage across it drops below recovery voltage level. Then it switches back to non-conductive state, causing the amplifier/switch to have negative gain, and the controlled light is not lit. The difference between breakdown or `firing` voltage and recovery voltage is the hysteresis factor.

Abstract: A position location device that is self powered and worn or carried by a child, pet, or a person with impaired senses such as sight or hearing. The device is a stand alone device, in that it is totally self contained and requires absolutely no external inputs of power or data.

A small child or a person with impaired senses carrying this device is allowed to walk or play freely. If the child or person with impaired senses walks off or gets lost, the device will automatically trigger at the preset time which will alert the monitoring person as to the location of the person.
