Abstract: The invention provides a retrofit LED lamp driver having a shunt switch to alternately shunt (for a first duration) and not shunt (for a second duration) received AC power. The first duration is concurring with a first polarity of each AC cycle of the AC power, for a first period comprising at least one AC cycle, and the first duration is concurring in a second, opposite polarity of the AC power, for a second period comprising another at least one AC cycle not overlapping with the first duration. Alternating the first and second periods are provided. Any DC offset in the current drawn caused by the shunting operation is thereby cancelled over time.

Abstract: Disclosures of the present invention describe a plant light raising and lowering apparatus. Particularly, a control module is configured for controlling a rope winch to complete at least one inching rotation along a clockwise direction or a counterclockwise direction, such that a base is driven by the rope winch so as to have an upward inching movement or a downward inching movement. Moreover, a counter is adopted for counting the direction, times and/or frequency of the inching rotation, and therefore the control module is able to know a total moving distance of the base by using the inching movement recording unit to record each time of the upward inching movement and each time of the downward inching movement. Therefore, a user is able to control the base to move back to a specific position such as an initial position or a previously-staying position.

Abstract: In the disclosed optically-fed transmitting phased-array architecture, transmitting signals are converted between the electrical domain and the optical domain by using electro-optic (EO) modulators and photodiodes. RF signal(s) generated from a relatively low frequency source modulate an optical carrier signal. This modulated optical signal can be remotely imparted to photodiodes via optical fibers. Desired RF signals may be recovered by photo-mixing at the photodiodes whose wired RF outputs are then transmitted to radiating elements of the antennas. The antenna array may generate a physical RF beam that transmits an RF signal that is focused on one or more selectable locations. Multiple RF beams may be simultaneously generated, each RF beam being capable of being directed to focus on a unique location or set of locations.
