Abstract: 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.

Abstract: An optical component array allowing expansion of the occupied bandwidth on an existing optical transmission network without disrupting signal traffic. Wavelength selective filters (16, 30; 20, 34) and optical components, such as amplifiers (18, 32) 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 (35, 37). 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.

Abstract: 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.
