An electromechanical actuator for an implantable hearing aid device including a mechanical output structure that has a first portion and a second portion, wherein the first portion is a mechanical attachment structure to attach a stapes prosthesis, and wherein the second portion is a wire-like member coupling the mechanical attachment structure to a magnetically permeable armature shaft assembly.

A telecommunications network includes a mobile phone with an audio-modulated vibrotactile module that responds to a telecommunications signal containing information about incoming speech from a called / calling party, for providing an audio-modulated vibrotactile module force containing information about the incoming speech from the called / calling party to vibrate a user's fingers, facial skin, wrist, cheek or other suitable location. The audio-modulated vibrotactile module has an audio-to-vibrotactile converter that responds to the telecommunications signal, for providing an audio-to-vibrotactile converter signal containing information about a vibration modulation of the incoming speech from the called / calling party. The audio-modulated vibrotactile module also has a vibrotactile actuator that responds to the audio-to-vibrotactile converter signal, for providing the audio-modulated vibrotactile module force in the form of a vibrotactile actuator force. The telecommunications system may also have the audio-to-vibrotactile converter. The vibrotactile actuator may be an electromechanical actuator arranged in the housing of the mobile phone for providing vibration to a user's fingers wrist or facial skin.

Process, apparatus, compositions and application modes are provided that relate to nanofiber spinning without the use of superacids in the spinning solution. The methods employ either acids or bases for a flocculation solution. The advances disclosed therein enable the use of nanofibers, including carbon nanotubes, for a variety of applications including, but not limited to, electromechanical actuators, supercapacitors, electronic textiles, and in devices for electrical energy harvesting.

A releasable security tag for attachment to an article of merchandise includes: a locking mechanism with a release for attaching the tag to the article of merchandise; an EAS resonant circuit or an RFID circuit for responding to a first RF signal at a predetermined frequency corresponding to the resonant circuit or to the RFID circuit; an ambient RF energy harvesting circuit; a release signal detection circuit coupled to and powered by the ambient RF energy harvesting circuit and an electro-mechanical actuator electrically coupled to the release signal detection circuit. The electro-mechanical actuator releases the locking mechanism whenever the release signal detection circuit receives a release signal.

An electro-mechanical actuator including a plurality of motors for driving an output shaft. The actuator may be incorporated into a window lift mechanism, such as a mechanism including a dual rack and pinion assembly. According to another aspect of the invention there is provided a variety of anti-back-drive mechanisms, e.g. clutches. A clutch according to one embodiment includes locking pawls that resist back-drive. In another embodiment, locking cams rotate relative to a carrier to resist back-drive. An actuator consistent with the invention may incorporate an impact mechanism including a flexible carrier. The carrier flexes to prevent impact forces at an output gear train from coupling to an input gear train.
