Abstract:
To provide a reporter drone (20), to approach a specific speaker in-between audience inside a big hole, a stadium, or in an open yard, or to take photos, record videos, and registers sounds from inside a narrow location where the drone's body (21) or a reporter can not approach, or can not get in. A triple camera (22) assembly, and a mike-speaker screen assembly (23), are installed and based separately at the ends of a two separate retractable motorized aerials (24), (30), installed at the ends of the bottom of the body (21) of a normal drone (20). When a drone (20) is used for reporting meetings with persons, the camera's antenna (24) is moving in the reverse direction of that moved by the antenna (30) of the mike-speaker screen (23), such that the mike-speaker screen (23) moves toward a speaker (person) while the cameras (22) are keeping a distance from him to get manage to get a photo for him.
Abstract:
A Safety/stability tool (20) for a mini aircraft (21) is provided, the aircraft block is to be penetrated by two parallely rigid, tensioned, and fixed ropes (22) extending from the top of the facade, toward the bottom basket (23), wherein a set of four side cylindrical bearings (24) are surrounding each rope (22) at the top and lower surfaces of the block (21). The ropes (22) serve as a guide, over which the mini aircraft (21) is guided to glide. In case of emergency, wherein the mini aircraft (21) gets idle, the mini aircraft 20 would not fell sideways, but it will fell down toward a basket (23), which is provided by a collapsible net (25), and a spongy base (26), while the mini aircraft (21) itself has an air cushion (27) too, installed on its bottom, this arrangement prevents the smash of the aircraft (21), and may let it bounce up and down along the ropes (22), until settling down inside the basket (23).
Abstract:
To provide a rescue drone (20), for rescuing an idle drone (21), it consists of an adjustable length hook (22) to engage with the idle drone, to carry it away, an L- shaped metallic tool (27) to push the idle drone away from the middle of the road, or to help in repositioning it to be at a side that permits for the hook (22) to engage with it, an emergency light (SOS) (28), to assist while hovering over the idle drone located in a road, an electric shock stick (29), which is to be used against any person approaching the idle drone to steal it, a speaker (30) and camera (31), to assist a security person in a command center to assess the case, talk with and warn any person who is trying to steal the idle drone, or to advise and guide a volunteer who is trying to help and assist in rescuing the idle drone.
Abstract:
To provide a motorized cleaning apparatus (20), that is manually effective in adjusting the horizontal destance of a rotatable brush (21) from a facade according to its variable protrusions details. On each of the the right and left hands of a worker supporting chair, rails (24) are installed, supporting from the back balance blocks, and supporting from their top sides two slideable beams (26), holding a motor housing, which is linked from its front side to an intermediate shaft (30) via a supporting frame (31), a belt installed on a drive gear from the motor side drives the intermediate shaft (30), which is driving via its end gears the brush's shaft (39), using two toothed belts. To support the brush (21), its shaft is linked from its both ends to the intermediate shaft (30) through a two U-shaped joints (40), which are inserted inside the ends of the intermediate shaft (30) and the brush's shaft (39), wherein carrier bearings are installed in-between them.
Abstract:
To provide an electric reciprocating razor (20), that automatically simulates perfectly the manual operation, which is a reciprocating motion of the blades head (21), by the user to release the repeatedly accumulating hair in front of the blades head (21), that blocks the blades from shaving (cutting) more hair. A hand held wet razor (20) is modified. The tubular housing of the razor contains a battery, powering a drive motor, which drives a pinion gear (30), driving a crown (31) gear, which drives a camshaft. The cam (32) tapered side is pushing away a spring loaded follower (34), that by its role pushes the blades head (21) in a reverse direction, in relation to the shaving forward direction, while when the cam's (32) tapered side is rotated, such that the convex side of the cam's (32) becomes with a slight contact with the follower (34), the follower (34) is retarded back by the spring, pulling the razor head (21) in the same cutting direction.
Abstract:
To provide an electric toothbrush (20), with a battery (21), drive motor (24), drive shaft (25), and a rotatable sealed disc (26), based inside a sealed casing (22) inside the handle (23) of the brush (20), while an eccentric rotatable semi- flexible arm (27) is fixed from one side on the sealed disc (26) near its edge, and fixed from its other side to the brush head (28). The drive shaft (25) rotates the disc (26), to rotate the arm (27) to rotate the brush head (28) in a circular path, but without changing the direction of the bristles of the brush head (28), such that the brush head (28) rotates toward the teeth lower side, and lets its bristle (29) applies a little pressure against the teeth crown while crossing it, then it rotates away from the teeth, to move down again, then moves toward the teeth gum, completing one circular rotation, and so on, simulating perfectly an actual manual brushing of the teeth.
Abstract:
Spiral plate spring (24) is used to drive unfolding a flexible display digital device (20) for use. The display (20) consists of three parts of equal length; the area of the central part (21) is either equal the total area of the first and the second side parts (22), (23), or equals the area of any part. A groove is made in-between the first side part and the central part (21), to create a space for installing the spiral spring (24) and its drive shaft (26). Two shafts (31), (40) with four end gears are installed in two grooves in- between the sides of the display side parts (22), (23) and central part (21), the four gears to be partially embedded inside corner extensions of the display (20) side parts (22) (23). Through a set of other gears and one belt in-between the two shafts (31), (40) and the spiral spring (24), the embedded gears are driven to drive the unfold of the display side parts (22), (23).
