A spur gear transmission has at least two meshing, toothed spur gears. A covering wall surrounds the spur gears circumferentially and in the direction of their rotational axes. The covering wall has an inner contour adapted to the outer diameters of the spur gears. Two annular gaps which transition into each other are formed between the covering wall and the spur gears. The annular gap is substantially concentric to a rotational axis. The covering wall surrounds the two spur gears circumferentially only over a part of the circumference, with a part of the outer circumference of the two spur gears or one of the two spur gears protruding outwards out of the covering wall. The part of the two spur gears or of the one spur gear that protrudes out of the covering wall is positioned on the lower face of the spur gears.

The device controlled by a finger allows the mobile phone record videos around the user. The device includes main parts: 1—mobile phone holding frame, 2—pivot to receive external force to create rotary motion on the pivot, thus, enable the pivot to rotate freely, 3—handle enabling the user to hold the 360° mobile phone rotary device in the palm of the user's hand to create an angle between the grip and the mobile phone, in addition, a 360° mobile phone rotating device may be added: 4—couplings or extensions to extend the handle and pivot holding frame or to increase the length between the handle and the pivot holding frame A and to create the angle between the handle and the mobile phone at will, 5—cable inside the cable conduit to transfer the rotational motion from the handle to the mobile phone holding frame, 6—curved or straight bars tangent to the pivot with reciprocating motion obtained by the external force and held by the gap between the horizontal bars on the shaft retainer.

A gear assembly includes an input shaft, a drive ring gear assembly, a pair of input/ring bearings, a driven pinion gear assembly, a first and second clutch members, and an actuator assembly. The first cutch member is fixedly connected to the input shaft. The drive ring gear assembly is mounted about the input shaft. The input/ring bearings are mounted so as to straddle the drive ring gear. The driven pinion gear assembly is operatively engaged with the drive ring gear. The second clutch member is slidingly mounted to the drive ring gear and the actuator assembly operates to move the second clutch member into engagement with the first clutch member to cause the drive ring gear to rotate when the input shaft rotates.

Systems and methods for controlling blind systems and other systems with moving parts are disclosed. Certain systems and methods couple to a blind system, and include one or more transceiving, processing, sensor, motion delivery, power delivery, and various other components for collectively or individually controlling a blind system to open or close its blinds. Certain systems and methods utilize preprogrammed control instructions stored locally, or user-initiated control signals received from remote devices to control the blind system.

A space curve mesh driving pair and a polyhedral space curve mesh transmission are disclosed. Said space curve mesh driving pair consists of a driving wheel and a driven wheel. Axes of the driving wheel and the driven wheel are intersected at an angle of 0°˜180°, and power transmission is realized by continuous mesh between the driving tines and the driven tines; a number of driving tines are provided on said driving wheel, and a number of driven tines are provided on the driven wheel; the driving tines are uniformly arranged on an end face of a cylinder of the driving wheel, and the driven tines are uniformly arranged on the circumference of a cylindrical surface of the driven wheel. Said polyhedral space curve mesh transmission consists of an above-mentioned space curve mesh driving pair. Motion is input from an input end, and is passed through a number of pace curve mesh driving pairs to realize the speed change, then is output from one or more output ends. Wherein, the space curve mesh driving pair is the core of the transmission. The invention has the advantages of compact structure, small size, light weight, stable transmission and flexible operation, and can be widely used in micro-mechanism field.
