| 20110079227 | Pressure regulation mechanism for inflatable in-ear device - An inflatable in-ear device incorporates a pressure regulating mechanism, for example a simple length of tubing or a relief/unloader valve, at the inflow or outflow from the inflating sheath inserted within the ear canal, thus allowing pressure regulation of the settable compound being injected for inflation of the sheath while avoiding excesses in pressure in the inflating compound and ensuring the comfort of the individual. | 04-07-2011 |
| 20110079229 | Settable compound delivery device and system for inflatable in-ear device - A method and apparatus for filling an expandable in-ear device having in-flow and out-flow canals including a plurality of chambers with elastic membranes in which the components of a settable polymer are held under high relative pressure. The component chambers are connected to a common mixing element which mixes the components before they are applied to the in-flow canal of an in-ear device. A sealed relief chamber is connected to the out-flow canal of the in-ear device and receives excessive mixed compound as it exits the in-ear device. The relief chamber is in contact with the elastic membranes of the component chambers such that when the elastic membranes contract the pressure in the relief chamber decreases, maintaining the pressure within a pre-determined pressure range. | 04-07-2011 |
| 20110158421 | In-ear device with selectable frequency response - An in-ear device comprises a main body for placement in the outer ear of a wearer and has at least two derivative canals each containing a filtering medium differing from one another in terms of their frequency suppression capabilities, and a preferably rotatable knob enabling selection of the respective filtering canal without the need for removal of the device from the ear. | 06-30-2011 |
| 20110158456 | Head-mounted device for settable compound delivery system for inflatable in-ear device - A head-mounted support device for carrying at least one un-inflated inflatable or expandable inner portion of an in-ear device thereon includes a main body adjustably mountable on a user's head, with at least one settable compound delivery device mounted thereon, and a at least one receptacle to receive an inflatable in-ear device inner portion. The invention also refers to a head-mounted settable compound delivery system kit, along with the earphone wire assembly that receives the customized in-ear device inner portions thereon. | 06-30-2011 |

| 20090220099 | METHOD AND APPARATUS FOR OBJECTIVE ASSESSMENT OF IN-EAR DEVICE ACOUSTICAL PERFORMANCE - A method and apparatus for objectively assessing acoustical performance of an in-ear device having a passageway extending there through use a dual microphone probe that removably engages the passageway. The acoustical performance of the in-ear device is performed with the in-ear device inserted into the ear canal of the user and a reference sound source. A clip holding the probe in an acoustic near field of the sound source permits real time calibration thereof. The method and apparatus allow on-site and in-situ measurement of a predicted personal attenuation rating of the device, a subject-fit re-insertion test, an acoustic seal test, a rating test, a stability and reliability test, as well as a protection test of the device with an assessment of a filtered predicted exposure level at the ear for a specific noise exposure level. The apparatus may be simply housed along with the sound source for in-field evaluation tests. | 09-03-2009 |
