Publication number: 20230085902Abstract: An input device comprises a plurality of optical vibration sensors mounted in a common housing. Each optical vibration sensor comprises a diffractive optical element; a light source arranged to illuminate the diffractive optical element such that a first portion of light passes through the diffractive optical element and a second portion of light is reflected from the diffractive optical element; and a photo detector arranged to detect an interference pattern generated by said first and second portions of light. The optical vibration sensor is configured so that in use, after the first portion of light passes through the diffractive optical element, the first portion of light is reflected from a reflective surface onto the photo detector. The input device is placed in contact with a surface of a solid body, and an object is brought into physical contact with the surface of the solid body, thereby causing vibrations in the solid body.Type: ApplicationFiled: December 1, 2022Publication date: March 23, 2023Inventors: Tobias Gulden Dahl, Magnus Christian Bjerkeng, Andreas Vogl, Odd Kristen Østern Pettersen

Publication number: 20200046563Abstract: A device (2) for insertion into an ear canal of a mammalian subject defines at least one sound path (16) therethrough. The second path (16) has an attenuating arrangement (14) therein which has a first configuration having a first level of attenuation and a second configuration having a second level of attenuation, higher than the first level. The attenuating arrangement (14) is such that upon application of an electrical control signal thereto, it is caused to change between the first and second configurations. The attenuating arrangement is stable in both first and second configurations such that the attenuating arrangement only draws electrical current from a power source when changing between the first and second configurations. The device further comprises a receiver (36) for receiving a command signal (34) from outside the device such that receipt of the command signal (34) causes the electrical control signal to be applied to said attenuating arrangement.Type: ApplicationFiled: May 19, 2017Publication date: February 13, 2020Inventors: Odd Kristen Østern Pettersen, Olav Kvaløy

Patent number: 9554733Abstract: A hearing protection device is disclosed which incorporates integrated audiometric testing, thereby allowing for testing without removal of safety hearing protection. The hearing protection is typically intended to be worn for the duration of a work shift, and allows for self-testing during the shift. Embodiments of the device may utilize a series of partial test sessions, so that each test session is kept brief so as to not interfere unduly with the work schedule. This may encourage frequent testing, hopefully aiding in early detection of potential hearing loss. Additionally, methods of use are disclosed.Type: GrantFiled: July 27, 2011Date of Patent: January 31, 2017Assignee: Honeywell Hearing Technologies ASInventors: Viggo Henriksen, Trym Holter, Olav Kvaløy, Asle Melvaer, Georg Esa Ottesen, Odd Kristen Østern Pettersen, Jarle Svean, Svein Sørsdal
