In one aspect, a control device for self-propelled machinery includes a central portion disposed between a first gripping portion and a second gripping portion and at least one pressure sensitive trigger control provided over either the first or the second gripping portion. The trigger control can be configured to reduce a speed of the self-propelled machinery by actuating a portion of a potentiometer for varying an electrical signal carried by the control device. In some aspects, the control device can electrically communicate with a control unit of the self-propelled machinery.

The present invention refers to a control device and to a control system of a bicycle electronic system as well as to a bicycle electronic system using the same, in particular a bicycle electronic gearshift. In particular, the control device of a bicycle electronic system comprises a containment casing, containing inside it at least one switch, and at least one manual actuation member faced at the containment casing and acting on a respective switch of the at least one switch for imparting at least one manual command to the bicycle electronic system. The containment casing is provided with a housing seat suitable for receiving at least one input multiplier able to be connected to the at least one switch to receive the manual command when the at least one manual actuation member activates the respective switch.

A lever device in which a lid is mounted to an opening portion of a lever member without dropping down therefrom and with a good visual quality is disclosed. The lever device comprises a lever member swingably supported in a fixed system, an opening portion provided in the lever member to open in a radial direction, and a lid that is engaged to the opening portion to cover the opening portion therewith, wherein the lid is provided with a thin portion. Deflections are generated in such a manner as to concentrate on the thin portion of the lid.

A selector lever includes a housing with front and rear ends and a lever with a shaft pivotally disposed on a cross-shaft. The shaft defines a shaft axis. The lever has a top that is disposed outside of the housing. A movable shaft moves substantially axially along the shaft axis. A pin, having first and second protrusions, is disposed adjacent to a bottom end of the movable shaft. A first detent plate is disposed on a first side of the movable shaft and includes at least a first slot that receives the first protrusion. A second detent plate is disposed on a second side of the moveable shaft and includes at least a second slot therein receiving the second protrusion. A first failure detection slot is associated with the first slot, permitting movement of the first protrusion therein in the absence of the second protrusion.

A safety handle assembly for use with a surgical instrument having an operative distal end portion is disclosed. The handle assembly includes a handle housing and a drive element movably mounted within the handle housing and connected to an associated operative distal end portion. A drive assembly is positioned within the handle housing and is engageable with the drive element to move the drive element within the handle housing. An actuator is movably mounted on the handle housing and an adjustable force-limiting mechanism is interposed between the drive assembly and the actuator. A force-limiting mechanism releasably connects the actuator to the drive assembly. The force-limiting mechanism is adjustable to preset the force at which the actuator separates or breaks away from the drive assembly.

A rotor system is disclosed for a reactive drive rotary wing aircraft. Apparatus and methods are disclosed for maintaining the rigidity of the rotor and eliminating play between flight controls and the rotor by mounting swashplate actuators to a flange rigidly secured to the mast. Apparatus and methods are disclosed for thermal management of the rotor in order to avoid bearing failure or loss of bearing preload. Methods include modulating the temperature of oil pumped over one or more of the mast bearing, swashplate bearing, and spindle bearing. The temperature of air passively or actively drawn through rotor may also be modulated to maintain bearing temperature within a predetermined range. Structures for reducing pressure losses and drag on components due to air flow through the rotor are also disclosed. A rotor facilitating thermal management by oil and air flow is also disclosed.

A park brake assembly includes a base. A park brake lever is pivotal about the base. A pawl is pivotal about a pawl pivot. The pawl is linked to the brake lever. A sector is attached to the base and the pawl releasably locks and unlocks relative to the sector. The pawl includes a pivot slot that receives the pawl pivot and wherein the pawl translates about the pawl pivot changing an angle of engagement of the pawl relative to the sector when subjected to a force.

A bicycle operating device is basically provided with a base member, a first operating member, a second operating member and an electric control unit. The base member is configured to be attached to a bicycle handlebar having a handlebar axis. The first operating member is supported on the base member such that the first operating member is configured to rotate about the handlebar axis while the base member is attached to the bicycle handlebar. The second operating member is supported on the base member such that the second operating member is configured to rotate about the handlebar axis while the base member is attached to the bicycle handlebar. The electric control unit generates a first signal and a second signal as the first operating member and the second operating member are operated respectively.

A multi-piece gear shift knob and a gear shift lever assembly including the same are disclosed. The multi-piece gear shift knob includes a grip portion and a lock portion. The grip portion includes an installation opening that extends through at least one face of the grip portion, and a partial thread form. The lock portion includes a partial thread form. The grip portion and the lock portion include corresponding attachment features such that when the lock portion is installed into the installation opening, the attachment features of the grip portion and the lock portion couple the lock portion to the grip portion.

Provided is an operation lever adapted to make a blade perform an action other than an up and down action by rotatably a grip around the shaft center of a lever shaft. The operation lever has a lever shaft operable back and forth, corresponding to an up and down action of a blade of a dozer unit, and a grip provided on an upper part of the lever shaft and capable of rotating in a clockwise direction and counterclockwise direction from a neutral position around a shaft center of the lever shaft by a predetermined rotation angle, corresponding to an angle action or a tilting action of the blade. The grip includes a return-to-neutral spring adapted to return the grip from a rotated position to a neutral position, and the rotation angle of the grip in the clockwise direction is set to be different from that in the counterclockwise direction.
