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: 8030409Abstract: The present invention provides a block copolymer of styrene and an unsaturated cyclic anhydride, such as maleic anhydride, a process for making a copolymer using controlled free radical polymerization in which certain parameters are adjusted to control the microstructure and molecular weight of the copolymer, and a method for using the block copolymer, including as a compatibilizer. Microstructure and molecular weight in the block copolymer can be controlled by adjusting the ratio of stable free radical to initiator. The copolymer can be made in a one step process and has a controlled microstructure that allows one block to be reactive toward several chemical moieties available in engineering polymers and the other block to be fully miscible with polystyrene or polymers miscible with polystyrene or polymers miscible with polystyrene such as polyphenylene ether.Type: GrantFiled: October 25, 2007Date of Patent: October 4, 2011Assignee: CID Centro de Investigación y Desarrollo Tecnológico, S.A. de C.V.Inventors: Enrique Saldivar Guerra, Alfonso González Montiel
