Abstract: The current invention provides a system and method for sharing Wi-Fi network primarily among neighborhood households to reduce cost of accessing internet. The invention comprises a server, an application software, multiple Wi-Fi networks registered for sharing, and multiple wireless devices with the application software. The invention comprises steps of registering user accounts including submission of payment method. Furthermore the said multiple registered Wi-Fi networks have their SSIDs, Wi-Fi login passwords, street addresses, and payment receiving methods registered with the server and stored in a database of the said server. The invention further comprises steps of using the application on wireless devices to select one or more cities to use registered Wi-Fi networks, and then download SSIDs, Wi-Fi login passwords, and addresses of registered Wi-Fi networks for the selected city or cities from the server, and then identify registered Wi-Fi network(s) by comparing SSIDs of discovered Wi-Fi networks at a place for using a registered Wi-Fi network in the selected city with downloaded registered Wi-Fi networks, and then login an identified registered Wi-Fi network by entering the downloaded network login password to connect a wireless device to the registered Wi-Fi network. The system and method to share Wi-Fi network further comprises steps of accepting payment by users of shared Wi-Fi networks to the server and sending payment from the server to a registered financial account by the Wi-Fi network owner.

Abstract: A tiltable electric tricycle as in the present invention comprises: (a) a frame, (b) a front fork mounted to the frame, (c) a front wheel with hub motor mounted to the front fork, (d) a seat, (e) a steering handle bar, (f) a pair of laterally spaced rear wheels on a common axle, (g) a support base with two quick release clamps for securing the axle of the rear wheels and the base has a shaft tube fitted into the bottom tube of the frame to connect to the frame rotatably, (h) a pair of footrests, (i) a battery to power the hub motor; furthermore the bottom tube points to the ground contact point of the front wheel; furthermore the frame has a horizontal oriented metal plate at the rear end of the bottom tube positioned above the support base of the rear wheels; and when the frame is tilted relative to the rear wheel support base to a certain extent, an end of the metal plate touches the rear wheel support base and thereby restricts the extent the frame can tilt; furthermore the axle of the rear wheels is secured to its support base using two quick release clamps and can be released quickly from the quick lease clamps so that the axle with two rear wheels can be separated from the rest of the tricycle for easy transportation; furthermore the two footrests are rotatably connected to the base and can swing toward the rear of the tricycle to reduce the width of the tricycle. In operation, the rider of the tricycle seats on the seat with two feet stepping on the footrests of the rear frame to keep balance and can tilt the front part of the tricycle around the axis line to maintain balance in response to road condition, speed, or turning while the rear part with two rear wheels remain stable.

Abstract: The present invention is a drone for spraying liquid such as pesticides, fungicides, herbicides, plant growth regulators, plant defoliators, and fertilizers over field crop. The drone comprises: a frame with a slender rigid beam in the middle and two base structures at the two ends, a rigid tube with an array of nozzles on elongated stems and the rigid tube is suspended below the beam structure with retractable wires, at least three propellers on motors with arms that are rotatably mounted to each of the two base structures of the frame, a power source positioned in one of the bases, at least one distance detector for measuring height of the drone above the ground, an antenna for sending and receiving communication signals, an electronic control system to operate motors and sensors, a container for a liquid material with a caped opening for refilling and an air pump to maintain a positive pressure in the container and electronic valve to allow liquid in the container under pressure to be released through a transfer line to be sprayed from the nozzles, and a remote controller for operating the drone. The invention provides a specialized drone that is able to spray liquid solutions over a wide strip of the field at a height close to crop canopy to achieve high efficiency and precision and reduced drift of sprays while the drone flies at a relatively high above the crop canopy for safe operation and avoid damage to crop by air turbulence.

Abstract: A method for folding flexible screen of electronic device comprises; a U-shaped channel element with a bottom and two side walls serving as the spine of a folding electronic device with a front body and a back body and the front and back bodies are flexibly connected to the side walls of the channel element. The inner surfaces of the front and back bodies each comprises a swing panel on the side of the channel element and the swing panels are connected to the rests of the inner surfaces with flexible joints. When the device is at a fully open position, the swing panels of the front and back bodies are positioned on tops of the side walls of the channel element and are aligned next to each other along the center axis line of the channel element. A flexible screen covers across the inner surfaces of the front and back bodies. As the front and back bodies fold, the swing, panels swing to maintain a constant contact with the side walls of the channel element and separate in the channel element. The separation of the swing panels in the channel element create a space for the flexible screen to have a curved folding without creating a crease to the flexible screen.

Abstract: A smartphone with flexible folding screen of the current invention comprises: a front body and a back body connected by hinges on the side, an exterior screen on the outer cover of the front body, a large flexible folding inner screen covering the inner covers of the front and back bodies, and a keyboard below the flexible screen. The invention further comprises a connection element with two ends in shape of rods serving as pins for the hinges connecting the front and back bodies and a long center portion having a flat surface on one side as a support plate for the flexible screen. The axis line of the rod ends is slightly above the surface of the support plate. The invention further comprises two swing panels on two sides of the support plate and the swing panels are flexibly jointed to the inner covers on the far side from the support plate and are isolated on other three sides. The swing panel, therefore, can swing downward when pressed from above. The front body and the back body have empty spaces underneath the swing panels to allow the swing panels to swing downward. The axis of the hinges is at or slightly above the surface level of the flexible screen so that the smartphone can fold fully. The flexible screen is permanently attached to the inner covers but is separated from or partially attached to the swing panels. The invention further comprises a plurality of mechanisms to control the swings of the swing panels to ensure a flat backing support for the flexible screen when the smartphone is at the full open position. When the smartphone is in open position, the support plate and the swing panel are at the same level with the inner covers of the front and back bodies and they together thereby provide smooth backing for the flexible screen. When the phone is in the folded position, the folding of the flexible screen results in curved folding of the flexible screen along the center line and the curving produces pressure on the swing panels and force the swing panels to swing toward the outer covers so that when the smartphone is in fully folded position the flexible screen has a curved folding along the center line and thereby has achieved folding without causing a crease to the flexible screen.

Abstract: An automated, adjustable-interval insect trap includes a plurality of individual cards having a surface coated with insect adhesive to capture insects. The cards are received on trays having wheels that engage a series of four parallel guide rails. By operation of a positioning mechanism, the trays carrying the cards are moved along the guide rails, one at a time, into an insect capturing position for a selected time interval. The positioning mechanism includes a timer, a drive motor, an axle operatively connected to the drive motor and a series of spaced fan plates mounted on the axle at longitudinally spaced positions. The plates function to sequentially pass the trays under the force of gravity along the guide rails as the axle is rotated by the drive motor.
