Systems and methods for effectively repelling pest animals (e.g., birds), including drones that adopt complex deterrent strategies (e.g., cooperative strategies), establishing a fuzzy boundary for a geofenced area and altering pest deterrent device flight patterns based on the characteristics of the fuzzy boundaries. Deterrence strategies can be selected based on the type of pest animals, and new deterrence strategies can be generated based on outcome feedback from previous strategies (e.g., combining aspects of preexisting deterrence strategies by utilizing an AI system). Drones can be automatically maintained by comparing current drone operational status with a predetermined threshold level.

Modular beehive apparatus
An improved modular beehive apparatus includes a hive body, a hive top, a hive bottom, a plurality of frames, and at least one securing means for securing at least the top to the body. In one embodiment of the present invention, the body is modular, thereby allowing multiple bodies to be stacked on top of one another.

The high-frequency power amplifier according to the present invention is provided with a coupler exhibiting a mutual inductance of a subtractive polarity on the GaAs chip, thereby making it possible to: cancel a mutual inductance between adjacent wires; reduce the spread of a second harmonic impedance with respect to a frequency when a signal source is viewed from a gate terminal of the GaN chip; and maintain a high efficiency of the power amplifier in a desired fundamental wave band. |

Switchless bi-directional amplifier using neutralized differential pair
A bi-directional amplifier (BDA) comprises a first pair of amplifier transistors and a second pair of amplifier transistors, wherein the first pair of amplifier transistors are cross-coupled with the second pair of amplifier transistors, and wherein the first pair of amplifier transistors and the second pair of amplifier transistors each comprise a differential common-emitter (CE) pair (or common-source (CS) pair) with equal transistor size or different transistor size. The BDA further comprises a plurality of blocking capacitors to decouple the collector and the base biases of the first pair of amplifier transistors and the second pair of amplifier transistors. Alternatively or additionally, the BDA further comprises two input/output baluns, through which a common voltage bias is applied to the collectors of each of the differential CE pairs (or drains of CS pairs in some implementations). The baluns enable single-ended measurement and characterization. |

Electronic envelope detection circuit and corresponding demodulator
An electronic envelope detection circuit includes an input signal detecting circuit having at least one MOS transistor configured to receive a radiofrequency input signal and to deliver an internal signal on the basis of the input signal. The biasing point of the at least one transistor is controlled by the input signal and a control signal. A processing circuit that is coupled to the input signal detecting circuit is configured to deliver a low-frequency output signal on the basis of the internal signal and further deliver the control signal on the basis of the output signal. In operation, the value of the control signal decreases when the average power of the input signal increases, and vice versa. |

Solar panel racking system and devices for the same
A solar panel racking system that can include end clamps, mid clamps, bottom clamps, L-foot adapter assemblies, rails, and L-foot assemblies. The solar panel racking system minimizes the use of tools by snapping many of the mounting components in place. The end clamps, mid clamps, and bottom clamps can snap over the rail sides and lock into upper detented portions of the rail sides. The upper detented portions are structured to prevent upward movement of the end clamps, mid clamps, and bottom clamps. The L-foot adapter body of the L-foot adapter assembly snaps over lower detented portions of rail sides and secures the rail to an L-foot assembly. The end clamps, mid clamps, bottom clamps, rails, and L-foot adapter assemblies are independent of the L-foot assembly, allowing a selection of L-foot assemblies to be used as appropriate with the solar panel racking system. |

Control system for motor
A control system for motor configured to control currents supplied to an armature coil and a field coil properly to achieve a required torque. The control system controls torque of a rotor by controlling a base torque generated by energizing an armature coil, and a field torque generated by energizing a field coil. When a target torque is equal to or greater than a predetermined torque, the controller controls the base torque and the field torque such that a ratio of the field torque to the target torque is increased greater than that of a case in which the target torque is less than the predetermined torque. |
