Publication number: 20220385433Abstract: A wireless node, such as an access point or a user equipment, includes a transceiver configured to transmit during a first frame in a first time interval and a second frame in a second time interval. The first and second time intervals are separated by an interframe space (IFS). The wireless node also includes a processor configured to generate a sensing waveform. The transceiver transmits the sensing waveform during the IFS. In some cases, the processor is configured to switch the transceiver from a transmit mode during the first time interval to a receive mode during the IFS. The transceiver receives a sensing waveform from a wireless node during the IFS.Type: ApplicationFiled: September 24, 2019Publication date: December 1, 2022Applicant: Nokia Technologies OyInventors: Enrico RANTALA, Klaus DOPPLER

Patent number: 10817071Abstract: A method, apparatus and computer program product are provided for displaying messages by reducing a reflectivity of a display. A display, such as a smart mirror, provides reflective properties and digital information. The reflectivity of some portions of the display may be altered such that the display provides the visual effect of steam. By varying the reflectivity in different portions of the display, messages may be provided via the display so as to appear written in the steam. Trigger actions, such as a user entering the vicinity, the detected sound of miming water, and/or the like, may cause the visual effect of steam or display of the message. A user may provide a message by a hand gesture, or writing the message in the air and see the message at is provided via a display. Users may transmit messages to other users, and may view received messages in the display.Type: GrantFiled: September 15, 2017Date of Patent: October 27, 2020Assignee: Nokia Technologies OyInventors: Enrico Rantala, Mika Kasslin, Janne Marin, Olli Alanen

Patent number: 9307551Abstract: Apparatuses may stay synchronized with a network via a beacon signal that is transmitted at a set interval. Various communication-related activities may be planned around an instance when a beacon signal is expected, or a target beacon transmission time (TBTT). While some networked apparatuses are active during every TBTT, other apparatuses may operate using a diluted beacon period that is an integer multiple of the network beacon signal interval. Diluted beacon intervals may initiate periods of time during which apparatuses may become “aware” of other apparatuses. Awareness may comprise information related to communication configuration, apparatus status, and services offered by the various apparatuses in the network. Awareness information obtained during an awake window may also comprise information on data-related tasks that are pending in one or more apparatuses which may allow for the control of further data conveyance activities.Type: GrantFiled: June 16, 2014Date of Patent: April 5, 2016Assignee: Nokia Technologies OyInventors: Mika Kasslin, Mikko Tirronen, Kari Leppanen, Sami Virtanen, Enrico Rantala, Markku Turunen
