Patent number: 9247354Abstract: A method and an associated configuration transmit data between a hearing device and an external unit. A first data packet is transmitted to the hearing device by the external unit. The first data packet is received by the hearing device and a second data packet is transmitted from the hearing device to the external unit. A predefinable fixed period of time elapses between the end of the receipt of the first data packet and the start of transmission of the second data packet. The external unit thereby “knows” when the first bit of the second data packet is to arrive. This offers the advantage that the reliability of a data transmission is improved. In the case of a packet-oriented data transmission fewer data packet repetitions are required, as a result of which the transmission speed increases.Type: GrantFiled: March 24, 2011Date of Patent: January 26, 2016Assignee: Sivantos Pte. Ltd.Inventors: Mihail Boguslavskij, Ulrich Schätzle

Patent number: 8379898Abstract: Hearing apparatuses with transmission facilities for the wireless transmission are to be miniaturized further. A transmission facility for a hearing apparatus and in particular a hearing device with an oscillating circuit including a capacitor and a coil as well as an electrical line is provided in or to the oscillating circuit, with the electrical line having a shielding. The electrical line includes a film conductor with a signal line and shielding line, the shielding capacitance of which is connected in parallel to the capacitor of the oscillating circuit. The shielding capacitance can be used together with the capacitance of the capacitor in a targeted fashion as an oscillating circuit capacitance. In this way, the parasitic shielding capacitance is used as a wanted capacitance. As the shielding capacitance of the film conductor is only subjected to minimal fluctuations, it only requires a small tuning capacitor for tuning the oscillating circuit.Type: GrantFiled: September 4, 2008Date of Patent: February 19, 2013Assignee: Siemens Medical Instruments Pte. Ltd.Inventors: Peter Nikles, Gottfried Rückerl, Ulrich Schätzle

Patent number: 8189832Abstract: With the date transmission in a hearing device system, overloads are to be avoided and the energy consumption during transmission is to be kept as low as possible. To this end, a transmission method and a corresponding system for the inductive transmission is proposed, in which the receiver returns an item of quality information relating to the received signal back to the transmitter. The transmission power of the transmitter is then dynamically varied as a function of the item of quality information. With unidirectional transmission, the transmitter can obtain an item of distance information relating to the distance of the receiver from the transmitter and thereupon adjust the transmission power accordingly.Type: GrantFiled: March 11, 2008Date of Patent: May 29, 2012Assignee: Siemens Audiologische Technik GmbHInventors: Mihail Boguslavskij, Jürgen Reithinger, Ulrich Schätzle

Patent number: 7831056Abstract: A hearing device, in particular a hearing aid, occupies a small volume and has high data transmission speeds for wireless transmission. In order to avoid using large volume frequency-stable components, for this purpose, an oscillator unit with a free-running oscillator is used instead. A receiver receives a synchronization signal cyclically. This is correlated to a reference signal in a correlator, such that the arrival time of the synchronization signal can be defined exactly. The free-running oscillator is then retuned correspondingly.Type: GrantFiled: July 21, 2006Date of Patent: November 9, 2010Assignee: Siemens Audiologische Technik GmbHInventors: Peter Nikles, Gottfried Rückerl, Ulrich Schätzle
