Publication number: 20240121640Abstract: Methods, systems, and devices for wireless communications are described. In some wireless communications systems, a base station may transmit a set of reference signals spanning a channel to a user equipment (UE), where each of the reference signals is associated with one of a set of transmit beams. The UE may measure a signal quality of each of the set of reference signals. In some cases, each measured signal quality may correspond to one of a set of subbands of the channel and one of the set of transmit beams. The UE may then transmit an indication of at least one signal quality associated with one of the set of subbands and one of the set of transmit beams. In some cases, the UE may indicate the at least one signal quality according to a configuration that may be indicated by the base station or selected by the UE.Type: ApplicationFiled: June 23, 2023Publication date: April 11, 2024Inventors: Mohammed Ali Mohammed HIRZALLAH, Arumugam CHENDAMARAI KANNAN, Srinivas YERRAMALLI, Xiaoxia ZHANG, Vasanthan RAGHAVAN, Tao LUO

Patent number: 9717412Abstract: A wireless fetal and maternal monitoring system includes a fetal sensor unit adapted to receive signals indicative of a fetal heartbeat, the sensor optionally utilizing a Doppler ultrasound sensor. A short-range transmission unit sends the signals indicative of fetal heartbeat to a gateway unit, either directly or via an auxiliary communications unit, in which case the electrical coupling between the short-range transmission unit and the auxiliary communications unit is via a wired connection. The system includes a contraction actuator actuatable upon a maternal uterine contraction, which optionally is a EMG sensor. A gateway device provides for data visualization and data securitization. The gateway device provides for remote transmission of information through a data communication network. A server adapted to receive the information from the gateway device serves to store and process the data, and an interface system to permits remote patient monitoring.Type: GrantFiled: November 4, 2011Date of Patent: August 1, 2017Assignee: GARY AND MARY WEST HEALTH INSTITUTEInventors: Masoud Roham, Enrique Saldivar, Srinivas Raghavan, Mehran Mehregany, Mitul Shah

Patent number: 8595302Abstract: A system and method for mediating the routing of asynchronous messages includes routing the asynchronous message to a first recipient, determining whether the first recipient opened the asynchronous message, and re-routing the asynchronous message to a second recipient who is qualified to receive and respond to the message if the first recipient fails to open the message (i.e., read, listen, display, act upon the message). In an embodiment, the message is re-routed to the second recipient if the first recipient fails to open the message within a deadline automatically imposed by the system when the message is of a certain type. In an embodiment, a mediator monitors if any recipient accepts responsibility for the asynchronous message and informs the other recipients that the asynchronous message may be deleted from their message queues.Type: GrantFiled: August 31, 2009Date of Patent: November 26, 2013Assignee: QUALCOMM IncorporatedInventors: Govindarajan Krishnamurthi, Stewart A.

Patent number: 8258041Abstract: A method of fabricating metal-bearing structures in an integrated circuit such as metal-polysilicon capacitors using conductive metal compounds. Defects due to organometallic polymers formed during the etch of a hard mask material are minimized by using a process that includes a plasma etch for the hard mask that achieves a predominantly chemical character using a fluorine-based etch chemistry. Using a low-temperature liquid-phase strip of the hard mask photoresist instead of an ash prevents further cross-linking of polymers formed during the plasma etch. Etching the metal-bearing material using a hot fully-concentrated mixture of ammonium hydroxide and hydrogen peroxide allows short etch times that are particularly shortened for tantalum nitride films deposited with a nitrogen concentration of about 30 percent or greater.Type: GrantFiled: June 15, 2010Date of Patent: September 4, 2012Assignee: Texas Instruments IncorporatedInventors: Srinivas Raghavan, Kalyan Cherukuri, Thomas E.

Publication number: 20110053372Abstract: A method of removing photoresist from a surface during the manufacture of an integrated circuit. Organometallic polymers and monomers are formed during the etch of a hard mask material defining the locations of a metal-bearing film, such as tantalum nitride, when photoresist is used to mask the hard mask etch. These organometallic polymers and monomers as formed are not fully cross-linked. A liquid phase solution of sulfuric acid and hydrogen peroxide used to remove the photoresist also removes these not-fully-cross-linked organometallic polymers and monomers, thus preventing the formation of stubborn contaminants during subsequent high temperature processing.Type: ApplicationFiled: August 28, 2009Publication date: March 3, 2011Applicant: TEXAS INSTRUMENTS INCORPORATEDInventors: Srinivas Raghavan, Kalyan Cherukuri, Murlidhar Bashyam, Richard A.
