Publication number: 20190110140Abstract: There is provided a personal device to be worn at the body of a user, comprising: an interface (20) for wireless data exchange with an external device (11, 39); at least one sensor (28, 42, 44, 46) for sensing a parameter indicative of the proximity of the personal device to the user; a use detection unit (40) for determining, by regularly analyzing signals received from the sensor(s), whether the personal device is presently worn by the user or not; and a control unit (38) for controlling operation of the personal device in a pairing disable mode as long as the use detection unit determines that the personal device is worn by the user and in a pairing enable mode as long as the use detection unit determines that the personal device is not worn by the user, wherein in the pairing disable mode the requirements for acceptance, by the personal device, of a pairing request received from an external device via the interface are more strict than in the pairing enable mode.Type: ApplicationFiled: April 7, 2016Publication date: April 11, 2019Applicant: Sonova AGInventors: Georg Dickmann, Andreas Breitenmoser

Patent number: 8601165Abstract: The invention relates to a method for synchronization in networks, whereby the local time (tloc) which is valid at the particular node, is updated at different nodes. For that purpose, timing messages are regularly transmitted by a freely selectable superior node (N1; N3; N6) and only by a superior node to an inferior node (N2, N3; N4-N6; N7), which receives the timing messages (M1-M8) and analyzes said messages for updating the local time (tloc) thereof. A minimum propagation time (dmin) is determined for a timing message (M1-M8) between an inferior node (N1; N3; N6) and a superior node (N2, N3; N4-N6; N7). When the inferior node (N2, N3; N4-N6; N7) receives a timing message (M1-M8), said inferior node extracts the local time of the superior node (N1; N3), which is contained in said timing message (M1-M8) and adds the minimum propagation time (dmin) thereto, in order to generate a reference time (tcomp,1-tcomp,8). Said reference time (tcomp,1-tcomp,8) is then compared with the proper local time (tloc).Type: GrantFiled: March 26, 2010Date of Patent: December 3, 2013Assignee: SMSC Holdings S.A.R.L.Inventors: Phillip Blum, Georg Dickmann

Patent number: 8014423Abstract: A reference time distribution system and method use a data transmission network having a plurality of nodes to distribute the House Sync signal. A network-wide time signal is generated using a reference time generator, and the network-wide time signal is then distributed over the network to the plurality of nodes. At each node, the network-wide time signal is converted to a local synchronization signal for use in performing synchronization of the timing of each node. Either network-inherent timing and/or additional time signaling is used to provide the nodes attached to this network with a network-wide notion of time. The time information is converted locally into synchronization signals or time information as required by a respective application. When data is transported over the network, delay compensation is performed to simultaneously output different data streams that have been synchronously input into the network, regardless of the data path.Type: GrantFiled: February 16, 2001Date of Patent: September 6, 2011Assignee: SMSC Holdings S.a.r.l.Inventors: Thomas Thaler, Georg Dickmann, Eric Roth, Christoph Heidelberger

Publication number: 20110090925Abstract: The invention relates to a method for synchronization in networks, whereby the local time (hloc) which is valid at the particular node, is updated at different nodes. For that purpose, timing messages are regularly transmitted by a freely selectable superior node (N1; N3; N6) and only by a superior node to an inferior node (N2, N3; N4-N6; N7), which receives the timing messages (M1-M8) and analyzes said messages for updating the local time (hloc) thereof. A minimum propagation time (dmin) is determined for a timing message (M1-M8) between an inferior node (N1; N3; N6) and a superior node (N2, N3; N4-N6; N7). When the inferior node (N2, N3; N4-N6; N7) receives a timing message (M1-M8), said inferior node extracts the local time of the superior node (N1; N3), which is contained in said timing message (M1-M8) and adds the minimum propagation time (dmin) thereto, in order to generate a reference time (tcomp,1-tcomp,8). Said reference time (tcomp,1-tcomp,8) is then compared with the proper local time (hloc).Type: ApplicationFiled: March 26, 2010Publication date: April 21, 2011Inventors: Philipp BLUM, Georg DICKMANN

Patent number: 6772267Abstract: Split IEEE 1394 bridges utilize individual portals or bundles of portals to communicate over a non-full-featured IEEE 1394 network such as a local or wide area network in combination with IEEE 1394 multi-portal bridges. Multi-portal bridges may be formed through the connection of several split bridges each with one or more IEEE 1394 portals over a core net. The core net is invisible to the IEEE 1394 nodes with respect to traffic originating from an IEEE 1394 bus for a destination in an IEEE 1394 bus, and the network elements allow for increased network scalability in both terms of physical size and levels of hierarchy. Useful properties of a core net such as availability of high-performance switches or increased reach are incorporated into an IEEE 1394 network.Type: GrantFiled: February 16, 2001Date of Patent: August 3, 2004Assignee: BridgeCo AGInventors: Thomas Thaler, Georg Dickmann, Thomas Boesch, Christoph Heidelberger, Manfred Stadler, Marcel Dasen
