The disclosure concerns an improved doormat having an anchored frame surrounding a center portion. A collapsible storage apparatus is rotatably coupled to the anchored frame and is configured to deploy into an expanded state and retract into a collapsed state. The collapsible storage apparatus is configured to store and secure delivered packages. In some embodiments, the center portion includes a doormat material disposed on an upper surface thereof. In some embodiments, the collapsible storage apparatus is disposed between the center portion and the anchored frame while in a collapsed state.

Doormat

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.

Efficient haptic actuator

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.
