Bone-conduction hearing-aid transducer having improved frequency response
InactiveUS20070041595A1Eliminates soldering wireEliminate useRecord carriersPiezoelectric/electrostrictive transducersFrequency spectrumBone structure
A hearing-aid device and a method for transmitting sound through bone conduction are disclosed. The hearing-aid device comprises a piezoelectric-type actuator, housing and connector. The piezoelectric actuator is preferably a circular flextensional-type actuator mounted along its peripheral edge in a specifically designed circular structure of the housing. During operation, the bone-conduction transducer is placed against the mastoid area behind the ear of the patient. When the device is energized with an alternating electrical voltage, it flexes back and forth like a circular membrane sustained along its periphery and thus, vibrates as a consequence of the inverse piezoelectric effect. Due to the specific and unique designs proposed, these vibrations are directly transferred trough the human skin to the bone structure (the skull) and provide a means for the sound to be transmitted for patients with hearing malfunctions. The housing acts as a holder for the actuators, as a pre-stress application platform, and as a mass which tailors the frequency spectrum of the device. The apparatus exhibits a performance with a very flat response in the frequency spectrum 200 Hz to 10 kHz, which is a greater spectrum range than any other prior art devices disclosed for bone-conduction transduction which are typically limited to less than 4 kHz.

Optical waveguide vibration sensor for use in hearing aid
InactiveUS20060107744A1Improve hearingVibration measurement in solidsRecord carriersPolymer optical waveguideLoudspeaker
A directionally-sensitive device for detecting and processing vibration waves includes an array of polymeric optical waveguide resonators positioned between a light source, such as an LED array, and a light detector, such as a photodiode array. The resonators which are preferably oriented substantially perpendicularly with respect to incoming vibration waves, vibrate when a wave is detected, thus modulating light signals that are transmitted between the light source and the light detector. The light detector converts the modulated light into electrical signals which, in a preferred embodiment, are used to drive either the speaker of a hearing aid or the electrode array of a cochlear implant. The device is manufactured using a combination of traditional semiconductor processes and polymer microfabrication techniques.

Foil composite card
Composite cards formed in accordance with the invention include a security layer comprising a hologram or diffraction grating formed at, or in, the center, or core layer, of the card. The hologram may be formed by embossing a designated area of the core layer with a diffraction pattern and depositing a thin layer of metal on the embossed layer. Additional layers may be selectively and symmetrically attached to the top and bottom surfaces of the core layer. A laser may be used to remove selected portions of the metal formed on the embossed layer, at selected stages of forming the card, to impart a selected pattern or information to the holographic region. The cards may be “lasered” when the cards being processed are attached to, and part of, a large sheet of material, whereby the “lasering” of all the cards on the sheet can be done at the same time and relatively inexpensively. Alternatively, each card may be individually “lasered” to produce desired alpha numeric information, bar codes information or a graphic image, after the sheets are die-cut into cards.

The method includes the steps of positioning a blank of thermoplastic sandwich material having a cellular core over a female die having an article-defining cavity defined by inner surfaces of the female die. Then, an inner portion of the blank is forced into the female die along a substantially vertical axis and against the inner surfaces of the female die to obtain deep-drawn material. During the step of forcing at least one outer portion of the blank immediately adjacent the female die is clamped to guide the at least one outer portion of the blank to travel into the article-defining cavity at an acute angle with respect to the vertical axis. Thickness of at least one side wall of the deep-drawn material is substantially the same as thickness of the blank of thermoplastic sandwich material. The deep-drawn material does not significantly stretch or tear during the step of forcing due to the clamping technique and mechanism.
