Abstract: Methods, devices, and systems for controlling a tissue-treatment motion by a surgical instrument are disclosed.

Abstract: A power-assisted steering system includes a control shaft arranged along a control shaft axis. An assist drive shaft defines a drive shaft axis and is arranged in a plane that is substantially transverse to the control shaft axis. The assist drive shaft is supported relative to the vehicle structure by a first bearing assembly and a second bearing assembly. A worm is disposed about the assist drive shaft. A worm gear is coupled to the control shaft, and the worm gear and control shaft are configured for rotation about the control shaft axis. The worm gear is configured for engaging the worm such that rotation of the worm and the assist drive shaft about the drive shaft axis causes rotation of the worm gear and the control shaft about the control shaft axis. The first bearing assembly is configured as an eccentric bearing assembly.

Abstract: A coupling assembly includes a first coupling end operably connectable to a first shaft and a second coupling end operably connectable to a second shaft. A coupling body of a plastic material is located between and operably connected to the first coupling end and to the second coupling end. The coupling body includes at least one spring segment allowing relative motion between the first coupling end and the second coupling end along a coupling assembly axis. Also disclosed is a vehicle steering system utilizing the coupling assembly.

Abstract: A method and apparatus for reducing rattle in a column mounted electric power steering system. A method of reducing audible noise in a steering system, generated by road impact energy and transmitted through a transmission medium, which includes a column mounted electric power steering system, including interrupting the transmission medium; and absorbing the road impact energy through the steering system. A column assist isolation system includes a sleeve disposed at a housing of an electric power steering system, a first bushing disposed at a first end of the sleeve, and a second bushing disposed at a second end of the sleeve. Both the first bushing and the second bushing include a compliant material.

Abstract: An automated gas cylinder monitoring system includes: a data storage collar associated with a gas cylinder including a resident memory and an insulated housing, the insulated housing being configured for coupling with a gas cylinder; a read/write probe for writing data to and receiving data from the resident memory of said data storage collar; measuring devices for determining the volume of gas in a gas cylinder; and a host computer for transmitting information to and receiving information from the read/write probe.

Abstract: An apparatus for transferring power and communication data across an annular gap comprises an inductively-coupled primary coil winding and secondary coil winding rotatable therein. Two signal oscillators are electrically coupled to a transistor for controlling current flow through the primary coil winding, thereby inducing a signal with a respective frequency in the secondary coil winding. An electronic switch operates so as to apply one of the two signals to the transistor for charging a capacitor coupled to the secondary coil winding, and operates so as to apply the other of the two signals to the transistor for discharging the capacitor. Actuation of control devices operate so as to modulate the impedance of the secondary coil winding. The inductive coupling of the two coil windings results in this modulation being mirrored by a modulation of the voltage developed across the primary coil winding.

Abstract: A motor vehicle steering column including a longitudinally collapsible mast jacket, a lower mount whereat the mast jacket is supported for vertical pivotal movement, and an upper mount consisting of a pair of stationary rigid strikers and a pair of releasable capsules on the mast jacket each of which receives in plug-in fashion and automatically retains a corresponding one of the strikers. Each of the capsules includes a socket, a plunger bore intersecting the socket, a plunger in the plunger bore, and a plunger spring biasing the plunger toward an extended position partially obstructing the socket. Each striker has a cam at a distal end thereof and an inverted frustoconical body. When the mast jacket is pivoted vertically up, the cams on the strikers shift the plungers inward in the plunger bores.
