Publication number: 20240056343Abstract: Device, methods, and systems for implementing aspects of orthogonal time frequency space (OTFS) modulation in wireless systems are described. In an aspect, the device may include a surface of an object for receiving an electromagnetic signal. The surface may be structured to perform a non-electrical function for the object. The surface may generate an electrical signal from an electromagnetic signal. The electromagnetic signal may be received from a transmitter. The transmitter may map digital data to a digital amplitude modulation constellation in a time-frequency space. The digital amplitude modulation constellation may be mapped to a delay-Doppler domain and the transmitter may transmit to the surface according to an orthogonal time frequency space modulation signal scheme. The apparatus may further include a demodulator to demodulate the electrical signal to determine digital data.Type: ApplicationFiled: October 13, 2023Publication date: February 15, 2024Applicant: Cohere Technologies, Inc.Inventors: Seshadri Sathyanarayan, Shlomo Selim Rakib

Patent number: 7444319Abstract: A method and apparatus are described for facilitating efficient retrieval and display of information to a computer user from sites on a network. An agent is described that monitors computer usage to determine the purpose or intent of a particular session. The agent analyzes information gathered during the monitoring to determine the user's purpose, and subsequently generates queries to search a plurality of network sites that may have information useful to the user related to the purpose. The queries are sent to the sites and when the search results are returned to the computer, the agent filters the search result entries to determine their relevance to the purpose. A summary document comprising the search result entries relevant to the users purpose is prepared and displayed to the user.Type: GrantFiled: September 27, 2000Date of Patent: October 28, 2008Assignee: Intel CorporationInventor: Seshadri Sathyanarayan

Publication number: 20080039097Abstract: In cellular and broadband wireless networks, specific nodes are assigned to handle functions such as radio resource management (BSC/BTS), session management (PDSN/GGSN/Access Gateways) and service switching (MSC, CSCFs). The function to guarantee Quality of Service, or QOS, is typically associated with the service being implemented and assigned to the one or more nodes implementing the service. There are also policy definition and control nodes (PDFs) identified within the standards. These manage static service level agreements that provide instructions to QOS mechanisms on different nodes within the network. With a move toward an all IP network and a services model with continuously changing requirements (such as user/terminal mobility, varying RF conditions), static QOS mechanisms become inadequate and the need for a dynamic and adaptive QOS mechanism becomes significant.Type: ApplicationFiled: August 8, 2007Publication date: February 14, 2008Inventor: Seshadri Sathyanarayan

Publication number: 20060010077Abstract: A secure pickup and delivery container includes a lockable door, a control unit, an access element, and an anchoring element, according to an embodiment. The control unit includes a processing element and a memory that can be programmed either on-site or remotely with access privilege information such as identity (e.g. of container, delivery person, etc.), location, date, time, frequency of access, and/or package-specific information. In an embodiment, access privilege information is programmed when an intended recipient of a delivery consummates a point of sale transaction, for example over the Internet or telephone. The access element can be a keypad, a biometric scanner, a card reader, a bar-code reader, and/or a wireless control element to read a programmable token such as a smart card. Delivery personnel can enter access request information into the access element, and if it favorably compares with the access privilege information, the control unit unlocks the door.Type: ApplicationFiled: September 12, 2005Publication date: January 12, 2006Inventors: Steve Dohrmann, Darren Yee, Peter Nee, James Dishman, Seshadri Sathyanarayan
