Patent number: 10679481Abstract: Systems and methods having a local processor at the extreme edge of an environmental monitoring/control system are disclosed. A sensor is provided in close proximity to the processing module. The processing module is a relatively simple processor capable of detecting the occurrence of one particular event, or a limited number of particular events. The processing is done with a relatively simple neural network. Processing module outputs indicate that a particular event has occurred. The processing module includes a memory into which values can be loaded that are determined by “pre-training” for use with the processing module. The downloading and use of such pre-trained values allows the processing module to efficiently detect particular events for which the values were pre-trained.Type: GrantFiled: November 14, 2018Date of Patent: June 9, 2020Assignee: Chaoyang Semiconductor Jiangyin Technology, CO. LTD.Inventors: Saeid Safavi, Dhinakar Radhakrishnan

Patent number: 9252921Abstract: Provided is a method and system for transmitting information. The method includes determining stream length information for at least one data stream to be transmitted and associating the stream length information with a system parameter message. The system parameter message including the associated stream length information is transmitted separately from the data stream. This process facilitates de-multiplexing of individual streams and the processing of stream data even if one or more individual streams are received in error.Type: GrantFiled: May 16, 2011Date of Patent: February 2, 2016Assignee: QUALCOMM IncorporatedInventors: Dhinakar Radhakrishnan, Bruce Collins, Shusheel Gautam

Patent number: 8599764Abstract: Techniques for transmitting overhead information to facilitate efficient reception of individual data streams are described. A base station may transmit multiple data streams on multiple data channels (or MLCs). The MLCs may be transmitted at different times and on different frequency subbands. The time-frequency location of each MLC may change over time. The overhead information indicates the time-frequency location of each MLC and may be sent as “composite” and “embedded” overhead information. The composite overhead information indicates the time-frequency locations of all MLCs and is sent periodically in each super-frame. A wireless device receives the composite overhead information, determines the time-frequency location of each MLC of interest, and receives each MLC at the indicated time-frequency location.Type: GrantFiled: October 18, 2004Date of Patent: December 3, 2013Assignee: QUALCOMM IncorporatedInventors: Rajiv Vijayan, Kent Gordon Walker, Richard Doil Lane, Dhinakar Radhakrishnan, Ramaswamy Murali

Patent number: 8412191Abstract: A system and method are provided for the management of user terminal (UT) cellular network services. The method includes: registering a UT in a cellular telephone network; accessing a management server; receiving UT-specific management instructions for cellular network services; and, requesting cellular network services for the UT in response to the UT-specific management instructions. In one aspect, the management server is embedded in the UT. Alternately, the management server is accessed via the cellular network. The UT-specific management instructions can be uploaded in a message received via a common control channel, such as Short Message Service (SMS) message or a paging channel message. As another alternative, the management server can be accessed via a UT Broadband subsystem with a hardwire management server interface, or a Wireless Local Area Network (WLAN) subsystem with a wireless management server interface, such as WiFi, Bluetooth, IEEE 802.11, or IEEE 802.15.Type: GrantFiled: September 29, 2005Date of Patent: April 2, 2013Assignee: QUALCOMM IncorporatedInventors: Dhinakar Radhakrishnan, Nikhil Jain

Patent number: 8280368Abstract: The disclosure is directed to a mobile communication device that determines when a performance disruption indicates a loss of synchronization with a broadcast signal and, in response, initiates reacquisition of the signal. Reacquisition techniques may include identifying and decoding only select portions of header information in the broadcast signal. Reacquisition may also be initiated in response to one or more deterministic triggers and during a test mode of operation.Type: GrantFiled: April 4, 2006Date of Patent: October 2, 2012Assignee: Qualcomm IncorporatedInventors: Ashok Mantravadi, Dhinakar Radhakrishnan, Murali Ramaswamy Chari

Patent number: 8200187Abstract: A system and method are provided for controlling a cellular telephone account User Terminal (UT). The method includes: registering a UT with an account in a cellular telephone network; uploading a credit for cellular telephone network services to the UT from a second party; and, converting the credit to an account balance. When the UT accesses a cellular telephone network service (i.e., makes a call), then the account balance is debited. In one aspect, the method accesses a credit server funded by the second party. Then, the credit is uploaded in response to accessing the credit server. For example, the credit server may be a module embedded in the UT. Alternately, the credit server is accessed via the cellular telephone network. For example, an Internet Protocol (IP) network-connected credit server may be accessed via the cellular network.Type: GrantFiled: September 29, 2005Date of Patent: June 12, 2012Assignee: QUALCOMM IncorporatedInventors: Nikhil Jain, Dhinakar Radhakrishnan, Donald John Jones

Patent number: 8005475Abstract: A wireless communications device is configurable to communicate with either one of two networks over a wireless medium, each of the two networks having a different air interface protocol. Additionally, the wireless device includes stored provisioning information for a set of networks of a first type and can map this first provisioning information into a second format for use with networks of a second type. The device also includes a non-volatile memory for storing default provisioning information so that some information remains available regardless of what is erased from the memory. The default provisioning information is enough to establish a connection over one of the available networks and allow reconstruction of a provisioning list.Type: GrantFiled: December 7, 2009Date of Patent: August 23, 2011Assignee: QUALCOMM IncorporatedInventors: Thadi M.

Publication number: 20100185717Abstract: Provided is a method and system for enhancing acquisition latency in a communications network. The method includes identifying control information associated with transmitted information and fragmenting the identified control information. Each fragment of control information is then associated with a corresponding transmission unit of the transmitted information. This process facilitates independent decoding and processing of the control information, which is embedded within physical layer packets.Type: ApplicationFiled: March 7, 2006Publication date: July 22, 2010Inventors: Dhinakar Radhakrishnan, Bruce Collins, Shusheel Gautam
