The current document is directed to various types of oscillating resonant modules ('ORMs'), including linear-resonant vibration modules, that can be incorporated in a wide variety of appliances, devices, and systems to provide vibrational forces. The vibrational forces are produced ley back-and-forth oscillation of a weight or member along a path, generally a segment of a space curve. A controller controls each of one or more ORMs to produce driving oscillations according to a control curve or control pattern for the ORM that specifies the frequency of the driving oscillations with respect to time. The driving oscillations, in turn, elicit a desired vibration response in the device, appliance, or system in which the one or more ORMs are included. The desired vibration response is achieved by selecting and scaling control patterns in view of known resonance frequencies of the device, appliance, or system.

Oscillating-resonant-module controller

An actuator includes a housing, a moving element and two springs connected between the housing and the moving element such that one of the two springs crosses the other of the two rotor springs without contacting the other of the two springs. A drive component causes the moving element to move.

The current document is directed to non-linear haptic actuators that use a rotor, rotor-suspension, and spring subsystem to efficiently generate vibrational forces in various types of devices and appliances in which the non-linear haptic actuators are incorporated. Non-linear haptic actuators can be designed and manufactured to be more space efficient than unbalanced-electric-motor and linear-resonant vibration modules and, because most of the frictional forces produced in unbalanced-electric-motor and linear-resonant vibration modules are eliminated from non-linear haptic actuators, non-linear haptic actuators are generally more power efficient and robust than unbalanced-electric-motor and linear-resonant vibration modules.

Efficient haptic accuator

The present document discloses motors and motor components that are constructed on a planar substrate. In some implementations, the planar substrate is made from rigid or semi-rigid sheet material, such as a printed circuit board ('PCB'). One or more coils are formed using spiral-shaped conductive traces that overlay the front and/or back surfaces of the substrate. In one implementation, a plurality of alternating right-hand and left-hand spiral-shaped conductive traces are separated by insulating layers, and connected with conductive vias to form inductive coils. Alternative coil-configurations include single-drive counter-wound coils and coils having a central ferrous or magnetic core.

Printed-circuit board coil and motor

A universal retractable step for use with the trailer hitch receptacle on automotive vehicles, wherein the step is movable from a stowed position to a utility position while remaining in the same horizontal plane. The step is readily adaptable to fit different trailer hitch receptacle sizes, as well as vehicles of differing heights, while including items to improve stability and security.

Universal stowable step

A stowable platform for use with a vehicle movable from the stowed to the extended position in a single plane. Once extended, the platform support is locked, preventing further movement, and the platform itself is capable of further extension or elevation.

Elevatable and extendable platform

A step or platform adapted to be mounted to the receiver of a trailer hitch selectively movable from a stowed to a deployed position without vertical movement, said platform is automatically locked in its selected position and includes a safety mechanism preventing inadvertent movement. The platform is separate from the mounting/control mechanism for storage and shipping, but secure and stable.
