Electronic pest control is the name given to any of several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects. Since these devices are not regulated under the Federal Insecticide, Fungicide, and Rodenticide Act in the United States, the EPA does not require the same kind of efficacy testing that it does for chemical pesticides.
These devices are usually combined with a motion sensor which is triggered by movement within the sensors range. This causes the device to emit high frequency noise which is uncomfortable to the cats, and inaudible to most humans (although they can still experience unpleasant subjective effects and, potentially, shifts in the hearing threshold ...
A motion detector attached to an outdoor, automatic light. A motion detector is an electrical device that utilizes a sensor to detect nearby motion (motion detection).Such a device is often integrated as a component of a system that automatically performs a task or alerts a user of motion in an area.
The electromagnetic parking sensor (EPS) was re-invented and patented in 1992 by Mauro Del Signore. [2] Electromagnetic sensors rely on the vehicle moving slowly and smoothly towards the object to be avoided.

[7] Although a dog would bark when it senses an intruder, a cricket stops singing when approached by an intruder. The crickets are kept in decorative cages resembling bird cages, and ...
mmWave sensing can be used inside vehicles to improve driver and passenger safety and comfort functions. [6] Notable advantages of using mmWave technology in vehicles revolve around its capability to operate effectively in spaces with low-lighting and limited visibility. mmWave sensing can penetrate materials like plastic, textiles, and glass, making it a contactless.
