Publication number: 20230413071Abstract: Presented are Ergodic Spectrum Management (ESM) systems and methods that take advantage of the presence of statistical consistencies (“ergodicity”) and correlations, such as a wireless network's average dimensional consistencies of probability distributions (in time, space, and frequency) of channel gains, to adaptively learn qualitative and quantitative network/user behavior; estimate or predict network performance; and guide locally implemented radio resource management (RRM) decisions of wireless multi-user transmissions in a manner such as to reduce interference and improve latency; connection stability; efficiency; and overall wireless performance. ESM also enhances end-users' Quality of Experience (QoE) by allowing movement across bands and regions as users/devices roam. A remote-cloud-based resource management implementation of ESM' s Learn-ed Resource Managers (LRMs) removes the need for heavy edge-computing close to radio cells.Type: ApplicationFiled: July 2, 2023Publication date: December 21, 2023Applicant: ASSIA SPE, LLCInventors: John M.

Publication number: 20230188311Abstract: Embodiments of the present invention provide systems, devices and methods for improving the performance and range of wireless communication systems. In various embodiments, a wireless and wireline architecture is implemented to allow a channel to more efficiently span physical barriers within the channel. The wireline portion of the channel may leverage pre-existing copper deployed within a building by interfacing copper with north and south transceiver nodes that allow the signal to propagate through a physical structure on the wire itself resulting in significantly less signal degradation compared to the signal having to traverse the physical structure wirelessly.Type: ApplicationFiled: February 14, 2023Publication date: June 15, 2023Applicant: ASSIA SPE, LLCInventors: John M.

Patent number: 9967673Abstract: An acoustic transducer comprises one or more electromagnetic motors that drive one or more sets of multiple diaphragms to provide acoustically efficient loudspeaker systems having dimensions that allow use in applications that would be difficult or impossible with traditional transducers. The diaphragms may be driven directly, inertially or fluidically. If diaphragms are driven by rods that pass through holes in the diaphragms, noise may be generated by air that leaks through the pass-through holes. This noise may be reduced or eliminated by measures that reduce or eliminate the air leakage.Type: GrantFiled: October 21, 2014Date of Patent: May 8, 2018Assignee: TYMPHANY HK LIMITEDInventors: Andrew David Unruh, Robert J.

Patent number: 9484984Abstract: A device for managing signal transport, on a cable level, in a communication system, and a method for using same, are provided herein. The device is connectable between one or more access multiplexers (e.g., Very-high-speed Digital Subscriber Loop Access Multiplexer (VDSLAM) or a switch) and a cable in said communication system. The device includes: a plurality of access multiplexer-side transceivers connectable to access multiplexer-related physical medium, associated with said one or more access multiplexers; a plurality of customer-side transceivers connectable to respective customer-related wire pairs of said cable; and a processor connected to said access multiplexer-side transceivers and said customer-side transceivers, said processor comprising means for reducing crosstalk among said customer-related wire pairs. In some embodiments, vectoring is used for the crosstalk reduction, thus implementing a so-called cable level vectoring (CLV).Type: GrantFiled: December 23, 2012Date of Patent: November 1, 2016Assignee: ACTELIS NETWORKS (ISRAEL) INC.Inventors: Ioannis Kanellakopoulos, Amit Priebatch, Elad Domanovitz, Mauricio Nurko, Tuvia Barlev

Patent number: 9301034Abstract: A method for operating an acoustic transducer is provided. The acoustic transducer includes a moving element and a fixed element, wherein the moving element is coupled to surrounding air. In the method, a signal-independent magnetic field is generated to urge the moving element into a rest position when no input signal is received; and a force is generated in response to the input signal and applying that force to the moving element to urge the moving element away from the rest position. The moving element is controlled by a combined influence of the signal-independent magnetic field and the signal-dependent force to generate acoustic vibrations in response to an audio input signal.Type: GrantFiled: October 21, 2014Date of Patent: March 29, 2016Assignee: TYMPHANY WORLDWIDE ENTERPRISES LIMITEDInventors: Kenneth L.

Patent number: 8942409Abstract: An improved electrodynamic acoustic transducer eliminates or reduces the need for flexible or elastic materials to suspend an internal magnetic element by using both static and dynamic signal-dependent magnetic fields to control its movement. In one implementation, the transducer has a magnet that moves within a surrounding tube. This tube in turn supports one or more electromagnetic coils that generate a dynamic signal-dependent magnetic field that causes the internal magnetic element to vibrate. The surrounding tube also supports one or more magnets whose location on the tube is fixed and whose magnetic fields provide appropriate restoring forces acting on the internal magnetic element. These fixed magnets may be replaced or supplemented by ferromagnetic materials.Type: GrantFiled: June 3, 2005Date of Patent: January 27, 2015Assignee: Tymphany HK LimitedInventors: Kenneth L.
