Patent number: 9454880Abstract: An apparatus for producing an electrosensory sensation to a body member (120). The apparatus comprises one or more conducting electrodes (106), each of which is provided with an insulator (108). When the body member (120) is proximate to the conducting electrode, the insulator prevents flow of direct current from the conducting electrode to the body member. A capacitive coupling over the insulator (108) is formed between the conducting electrode (106) and the body member (120). The conducting electrodes are driven by an electrical input which comprises a low-frequency component (114) in a frequency range between 10 Hz and 500 Hz. The capacitive coupling and electrical input are dimensioned to produce an electrosensory sensation. The apparatus is capable of producing the electrosensory sensation independently of any mechanical vibration of the one or more conducting electrodes (106) or insulators (108).Type: GrantFiled: December 12, 2014Date of Patent: September 27, 2016Assignee: Senseg OYInventors: Ville Makinen, Petro Suvanto, Jukka Linjama

Publication number: 20140005567Abstract: Embodiments of tactile stimulation apparatuses and components of such apparatuses are generally described herein. For example, in one embodiment, a tactile stimulation apparatus is provided. This tactile stimulation apparatus has a composite section comprising an insulation region and a semiconducting region that is proximate to the insulation region. This insulation region is touchable by a body member. Additionally included is a voltage source proximate to the semiconducting region. Here, the voltage source is configured to charge the semiconducting region to an electric potential, which produces an electrosensory sensation on the body member.Type: ApplicationFiled: May 14, 2013Publication date: January 2, 2014Applicant: Senseg OYInventor: Ville Makinen

Patent number: 8457730Abstract: A computerized method for determining a test subject's (TS) hearing threshold (HT). An acoustic stimulus (AS, 102) is applied the test subject's (TS) ear. The stimulus intensity is increased during a ramp, with a predetermined dependency on time, such that the intensity begins below the hearing threshold and ends above it. The test subject's brain response (104), which includes a transient brain response (TR)1 is non-invasively recorded during the ramp section. The stimulus-response cycle is repeated several times. The recorded brain responses and stored a-priori information on transient brain response to the acoustic stimulus are used to determine a combined time interval between the acoustic stimulus and the transient brain response. The test subject's hearing threshold is determined based on the predetermined dependency on time of the intensity during the ramp and the combined time interval between the acoustic stimulus and the transient brain response.Type: GrantFiled: November 8, 2007Date of Patent: June 4, 2013Assignee: Senseg OyInventor: Ville Mäkinen
