A flapping wing driving apparatus includes at least one crank gear capstan rotatably coupled to a crank gear, the at least one crank gear capstan disposed radially offset from a center of rotation of the crank gear; a first wing capstan coupled to a first wing, the first wing capstan having a first variable-radius drive pulley portion; and a first drive linking member configured to drive the first wing capstan, the first drive linking member windably coupled between the first variable-radius drive pulley portion and one of the at least one crank gear capstan; wherein the first wing capstan is configured to non-constantly, angularly rotate responsive to a constant angular rotation of the crank gear.

The present invention provides an unmanned aerial vehicle comprising: a body part having an inner space filled with a particular gas; and a plurality of wing parts mounted on the body part and providing a propelling force, wherein each of the wing parts comprises: a fin part having a first rib and a second rib mounted thereon; a first servomotor and a second servomotor connected to one end of the first rib and one end of the second rib, respectively, to move the other end of the first rib and the other end of the second rib in a predetermined control angle range; a control unit for controlling the first servomotor and the second servomotor to make the first rib and the second rib move while having a particular phase difference therebetween; and a third servomotor connected to the first servomotor and the second servomotor to rotate the fin part in order to determine the propelling direction of the body part.

An improved drone with 4 flat wings reciprocating up and down, complete with motor and electronics. Appendages on each wing's surface allow air to pass across it during the up-motion, and block it in the down-motion; this creates lift and permits flight and manoeuvres. The drone resembles either a flying bird or an insect, depending on wing motion and on passive attachments appropriate for the respective resemblance, making for inconspicuousness. The drone can execute complex work, either as solitary or in a team, either in flight or at rest in various places, after approaching and adhering expertly.

A wing flapping apparatus includes a motive power source; a power transmission mechanism; and a wing unit driven by the power transmission mechanism. The power transmission mechanism includes a rotation transmission member configured to rotate upon reception of motive power transmitted from the motive power source; a slider configured to linearly reciprocate in an X-axis direction upon reception of the motive power transmitted from the rotation transmission member and a rotating body configured to reciprocate in a rotation direction upon reception of the motive power transmitted from the slider. The wing unit is configured to swing such that its distal end moves approximately in the X-axis direction as the rotating body reciprocates in the rotation direction. The power transmission mechanism further includes a pair of crank arms each configured to connect the rotation transmission member and the slider. The pair of crank arms each has: one end rotatably connected to the rotation transmission member and the other end rotatably and slidably connected to the slider.

A method for exterminating a target on a host using ultraviolet (UVC) light. The method includes providing a device configured for emitting UVC light for exterminating the target, selecting a host type from a plurality of host types for the target to be exterminated from, and selecting a target type from a plurality of target types for the target to be exterminated. The method further includes assigning an intensity and an exposure time of UVC light to exterminate the target, wherein the intensity and the exposure time are based at least in part on the host type selected and the target type selected, and wherein the intensity and exposure time together define an extermination program. The method further includes controlling the device to emit UVC light to exterminate the target according to the extermination program.

A novel electromagnetic actuator designed to operate at system resonance, used in the construction of a unique vehicle system, is presented herein. An exemplary embodiment of the vehicle system is based on an electromagnetic actuator coupled to a plurality of actuating members of a micro aerial vehicle. Attributes of this type of actuation offer several enhancements over traditional approaches. The unique use of an electromagnetic actuator lends itself to a near unlimited number of coil cross-sectional designs that can be optimized to meet performance requirements while maintaining minimal costs of fabrication.
