Patent number: 10409311Abstract: Apparatus embodiments of the invention are disclosed for requesting power via a wired interface. In example embodiments, a pull-down circuit in the apparatus acting as a power consumer when there is no energy in the apparatus, is connected via a configuration line over a cable to a power provider device. The apparatus may be in a power down mode, it may have an empty battery, or it may have no battery. The pull-down circuit is configured to use energy from the configuration line to pull down a voltage on the configuration line, to signal the power provider device to provide power over another line of the cable to the apparatus.Type: GrantFiled: January 16, 2018Date of Patent: September 10, 2019Assignee: Nokia Technologies OyInventors: Pekka Leinonen, Kai Inha, Pekka Talmola, Timo Toivola, Teemu Helenius, Seppo Jarvensivu, Kristian Vaajala, Tino Hellberg

Patent number: 10291015Abstract: Electrical apparatuses with connector overheating protection and methods for protecting electrical apparatuses from connector overheating during current sinking and current sourcing operations are presented. The electrical apparatus includes an electrical connector and a temperature sensor, which is in direct contact with a physical part of the electrical connector. The temperature sensor monitors a temperature of the electrical connector during current sinking and current sourcing operations. During current sinking, if the temperature sensor senses a predetermined level of overheating of the electrical connector, then the sourcing of current to the electrical apparatus is switched off. During current sourcing, if the temperature sensor senses a predetermined level of overheating of the electrical connector, then the sourcing of current to the sinking device is switched off.Type: GrantFiled: August 26, 2016Date of Patent: May 14, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Seppo Järvensivu, Esa Eklund, Teemu Helenius

Patent number: 6031825Abstract: A system for providing an IR-link between a mobile phone and its accessories to transmit audio, control, and data signals between them in an apparent full-duplex real time mode using a conventional half-duplex IR-transceiver with suitable FIFO registers and control means. The "direction" of the half-duplex channel is "switched" by the system which may be embodied in an IR-link module, having transmission channels for digital full-duplex audio signals, slow data messages and fast data messages, and for some control data. The module is connected to the baseband of a phone through a baseband interface (BBIF) and communicates through a media interface (MIF) and an infrared interface (IRIF) with free air space or a lightguide. A link-specific low-level protocol is used for audio and slow data message transmission but the link hardware of the module may also support other protocol implementations. The system may be implemented in hardware and/or software.Type: GrantFiled: July 23, 1996Date of Patent: February 29, 2000Assignee: Nokia Mobile Phones LimitedInventors: Terho Kaikuranta, Markku Lipponen, Seppo Jarvensivu, Toni Sulavuori
