  • Patent number: 11425897
    Abstract: A remote notification electronic rodent trapping system and method is provided having a plurality of rearming electronic rodent trapping devices configured to wirelessly communicate trap information to a base station that is in communication with a cloud server. When a trap is activated by a rodent trigger it changes from a set state to a kill alert state and initiates a killing cycle. The trap waits a first time period and then sends a notification signal to the base station of trap activation which the base station forwards to the cloud server. The cloud server waits a second predetermined time period before sending a pushed notification to a remote user of the trap's kill alert state. If the trap rearms prior to expiration of the second time period, it alerts the base station which notifies the cloud server. The cloud server updates trap status to the set state and does not send a notification to the user.

  • Patent number: 7286056
    Abstract: Systems and methods for detecting presence and movement of pests. Various embodiments of a pest detection system can be based on, for example, a beam-interrupt detector or a thermal imaging device. The beam-interrupt detection based system can provide functionalities such as counting of pests crossing a given beam. A plurality of such beams at different heights can also allow distinguishing different sized pests. The thermal imaging based detection system can provide functionalities such as tracking movement of pests. A recording can be triggered by detection of pest movement, thereby improving the efficiency of recording and reviewing information indicative of presence and movement of pests in a monitored area. Movement of pests can be monitored on a passive basis, or by providing a stimulus that induces movement.

  • Patent number: 7227452
    Abstract: Birds carry many parasites and other diseases, which pose a health risk to humans which come into contact with their habitat. However, ultrasonic waves agitate and deter birds and other pests from roosting in nearby areas. The disclosed device utilizes solar energy to power a battery pack, which in turn activates both a tone generator and its adjoining amplifier to create and emit the annoying ultrasound. In this way, birds are dissuaded from gathering in particular areas where the ultrasonic device is in use, and humans are provided a more healthy and disease-free environment.

  • Patent number: 7173534
    Abstract: A computer based bird control system is provided. The bird control system utilizes an impactor that is attachable to a structure, such as an I-beam or other similarly sized and dimensioned metal object, to create an acoustic impact noise similar to a whacking of the structure. The impactor is preferably actuated at a random or a semi-random impact rate such as around once every ten seconds. The acoustic impact noise may be provided in addition to the playing of bird predator or other deterrent sounds maintained in audio files on the computer. The system also provides audio and/or physical bird presence detection within a monitored area. Detection of the presence of a bird may be used as a trigger for the actuation of the impactor and/or predator/deterrent sounds. Actuation of the impactor and/or sound files may be accomplished via a schedule through the use of timer files in addition to or in place of animal presence detection.

  • Patent number: 7106180
    Abstract: An acoustic warning or alerting system for directing an audible warning signal to at least one intended recipient, while reducing the chance that the warning signal will be heard by others within the proximity of the system. The system includes a modulator for modulating an ultrasonic carrier signal with a processed audio signal, a driver amplifier for amplifying the modulated carrier signal, and a parametric array of acoustic transducers for projecting the modulated and amplified carrier signal through a propagation medium for subsequent regeneration of the audio signal along a pre-selected projection path. The parametric array of audio transducers operates by employing the nonlinear interaction between high frequency sound components and the propagation medium to generate at least one highly directional beam of lower frequency sounds within the propagation medium.
