The present disclosure provides a pest control device, crafted to mimic a tree, amalgamates physical, chemical, and biological lures, including light, ultrasound, infrared, and specific chemicals, to efficiently attract target insects. Periodically, the device photographs a set area, such as the trunk of the faux tree, equipped with electrified nets. Leveraging a pre-trained machine learning processor, the system detects the presence of specific insect species within these images. Upon identifying a target insect, an electric shock is released in the respective area, neutralizing the insect. The device also features a system to collect and process the insect remnants. Furthermore, these artificial trees can be interconnected to form a network, utilizing big data and machine learning, thereby enabling the formulation of optimal strategies for pest control across specific geographical regions.

Integrated insect control system

An optical component array allowing expansion of the occupied bandwidth on an existing optical transmission network without disrupting signal traffic. Wavelength selective filters () and optical components, such as amplifiers () are arrayed for use with a wavelength division multiplexed optical transmission system to transmit a selected portion of a transmission spectrum to an amplifier path and reflect the remainder of the spectrum. Wavelength selective filters and associated amplifiers are arranged in a cascade configuration with a bypass path (). Additional wavelength selective filters and amplifiers can be added in the bypass path without disrupting existing signal traffic, and such additions can provide for a remaining bypass path, thus allowing further expansion. This configuration provides an expandable amplifier array with a low initial cost. In a further embodiment, a center segment of the input transmission spectrum is passed through an amplifier path () and a red/blue splitter () having a transition region within the band of the center segment further splits the input spectrum into two expandable amplifier arrays paths. The two arrays allow reduced insertion loss and optimization of amplifier characteristics for multi-channel systems.

Expandable optical array

An optical amplifier assembly integrating wavelength selective input and output filters. Integration of wavelength selective filters with a doped fiber optical amplifier stage provides a modular amplifier for use in wavelength division multiplexed optical communication systems. In one embodiment, a center tap provides access to the selected light signal after a first amplifier stage, allowing signal modification before returning the light signal to a second amplifier stage of the integrated amplifier. In a further embodiment, a pump interconnect is provided between the first and second amplifier stages to allow operation of both amplifier stages from a single pump light source.
