Publication number: 20240151678Abstract: The invention is notably directed to an oscillating reaction device. The device basically includes a structured layer of a matrix material and structural elements. Cavities are defined (for example, as blind holes) in the structured layer to allow the cavities to be filled with an oscillating reaction liquid containing nonpolar molecules of a given molecular species, with a view to triggering an oscillating reaction. Centers of the cavities are arranged according to a 2D lattice, whereby pairs of nearest-neighbor cavities of said cavities are, each, separated by a portion of the matrix material. This portion of material is selectively permeable to said nonpolar molecules. This, in operation, yields an inhibitory chemical coupling of the filled cavities of said pairs of nearest-neighbor cavities, where the inhibitory chemical coupling is mediated by said nonpolar molecules. Also, the structural elements connect the cavities to yield a positive chemical coupling of the filled cavities.Type: ApplicationFiled: November 7, 2022Publication date: May 9, 2024Inventors: Armin Knoll, Heiko Wolf, Philippe Marc Nicollier, Daniel Widmer, Jacqueline Figueiredo da Silva

Patent number: 10917914Abstract: Systems and/or methods of receiving communications at a receiving node that communicates with a transmitting node over a first communication channel and a second communication channel are disclosed. The method includes receiving, at the receiving node, a request-to-send message from the transmitting node over the first communication channel, the request-to-send message indicating that the transmitting node has data to be transmitted to the receiving node over the second communication channel, determining at the receiving node whether the second communication channel is available for reception of the data, in response to determining that the second communication channel is available for reception of the data, reserving the second communication channel for use by the transmitting node, and receiving the data from the transmitting node over the second communication channel.Type: GrantFiled: July 24, 2019Date of Patent: February 9, 2021Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventors: Ashim Biswas, Daniel Figueiredo, Damanjit Singh, Oscar Zee

Patent number: 10555342Abstract: According to certain embodiments, a method by a radio node (110, 115) operating in multiple modes for power detection includes operating in a first mode. While operating in the first mode power levels of transmissions on a channel are compared to a first threshold to determine whether the channel is free. While operating the radio node (110, 115) in the first mode, power levels within a specified range are detected during a first time period. In response to detecting the power levels within the specified range during the first time period, the radio node (110, 115) is switched to a second mode that is a duty-cycle mode. While operating the radio node (110, 115) in the second mode, the power levels of the transmissions on the channel are compared to a second threshold during a first portion of a duty cycle and to a third threshold during a second portion of the duty cycle to determine whether the channel is free. The third threshold is different from the second threshold.Type: GrantFiled: October 5, 2016Date of Patent: February 4, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Jung-Fu Cheng, Håkan Andersson, Ashim Biswas, Daniel Figueiredo, John Skördeman

Patent number: 10542566Abstract: A technique for performing a clear channel assessment (CCA) in an unlicensed radio frequency (RF) spectrum is described. The CCA is performed for transmitting data (420) according to a first radio access technology (RAT) in coexistence with a second RAT. As to a method aspect of the technique, signals (411) are received in the unlicensed RF spectrum. The received signals (411) are processed according to an operating state. The processing in a first operating state (402) causes a first delay that is greater than a second delay caused by the processing in a second operating state (404). The operating state depends on the presence of data (420) to be transmitted according to the first RAT in the unlicensed RF spectrum. The CCA is performed based on the processed signals.Type: GrantFiled: January 27, 2017Date of Patent: January 21, 2020Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Håkan Andersson, Ashim Biswas, Daniel Figueiredo

Patent number: 10425964Abstract: Systems and methods of performing a listen-before-talk (LBT) radio protocol in a communication system are provided. In one exemplary embodiment, a method (600) by a radio component (403, 503) of a wireless device (400, 500) may include receiving (601), by the radio component, from a baseband component (401, 501) of the wireless device, transmit data during a transmit-time interval associated with a synchronous wireless communication system. Further, the method may include, detecting (603), by the radio component, that a medium associated with an asynchronous communication system is available. Also, in response to detecting, the method may include, transmitting (605), by the radio component, the transmit data on the medium during the transmit-time interval.Type: GrantFiled: November 20, 2015Date of Patent: September 24, 2019Assignee: Telefonaktiebolaget LM Ericsson (publ)Inventors: Daniel Figueiredo, Håkan Andersson, Ashim Biswas, Jonas Fröberg Olsson, Damanjit Singh
