Patent number: 11905236Abstract: The present invention relates to a dynamic chemical network that mimics the transfer of information and ultimately produces a chemical response, for example a readable signal. More specifically, the invention discloses a dynamic system able to selectively sense a biologically-relevant analyte, such as cysteine, in its reduced or its oxidized form (cystine) in aqueous media and in a biofluid (such as urine) for diagnostic application. Due to this property, said dynamic system is useful for the detection of cysteine or its derivatives in biological fluids such as urine.Type: GrantFiled: April 4, 2019Date of Patent: February 20, 2024Assignee: CONSEJO SUPERIOR DE INVESTIGACIONES CIENTIFICAS (CSIC)Inventors: Igancio Alfonso Rodriguez, Jordi Sola Oller, Maria Lafuente Fabra

Patent number: 11451312Abstract: Disclosed is a method of calibrating phase alignment of signals from multiple transmit antennas on multiple channels during OTA testing of a MIMO DUT, including generating a noisy test signal by adding noise to a signal pattern and transmitting the noisy test signal to the DUT on first and second channels OTA and sweeping a relative phase of the signal pattern, but not the added noise, in the first and second channels, while receiving from the DUT reports of a SNR for a received signal on at least one of the first channel and subsequently on the second channels. The method also includes analyzing variation in the SNR to determine phase alignment of the first and second channels, as received and processed by the DUT and using the determined phase alignment to perform OTA testing of the DUT. The method can also include receiving a RSRP and/or a RSSI.Type: GrantFiled: June 30, 2021Date of Patent: September 20, 2022Assignee: Spirent Communications, Inc.Inventors: Alfonso Rodriguez-Herrera, John Douglas Reed

Publication number: 20220155439Abstract: In a method of imaging, a first transmission is carried out in a first direction. The reflected signals are received using a plurality of receiving devices. For each device, a two/three dimensional data set is formed. The first dimension (26b) represents the depth or range and the second dimension (26a) represents lateral distance. The optional third dimension (26c) represents an orthogonal lateral distance. The data set is formed by calculating times of flight for each pixel within a grid. The receive time is then assigned to each pixel. A data set is generated for each receiver, which results in a three/four dimensional data set from the first transmission of signals. A second transmission of signals is made in a different direction or from a different position. The signals received from the second transmission are received in the same way as those received from the first transmission.Type: ApplicationFiled: July 10, 2020Publication date: May 19, 2022Inventors: Ole Marius Hoel RINDAL, Andreas AUSTENG, Alfonso RODRIGUEZ-MOLARES

Patent number: 10587350Abstract: The disclosed systems and methods for conducted massive MIMO array testing uses an efficient method of utilizing hardware resources for emulating signals from a massive MIMO base station transceiver to a MIMO mobile unit as dictated by a channel model; and also for emulating signals from a MIMO mobile unit to a massive MIMO BS transceiver, as dictated by a channel model. The system uses a phase matrix combiner to emulate the angular behavior of the propagation using virtual probes, combined with a radio channel emulator to create the temporal, multipath, and correlation behavior of the propagation. Using a phase matrix function increases the number of antenna elements that can be utilized in a massive MIMO array emulation while keeping the required number of fading channels within the radio channel emulator at a reduced number, thus forming a cost effective, yet realistic test system for massive MIMO testing.Type: GrantFiled: June 3, 2019Date of Patent: March 10, 2020Assignee: Spirent Communications, Inc.Inventors: Alfonso Rodriguez-Herrera, John Douglas Reed

Patent number: 9738123Abstract: A vehicle warning includes a tire pressure monitoring device disposed in each tire of the vehicle. Each tire pressure monitoring device obtains information regarding pressure within the associated tire and communicated the tire pressure information in a wireless manner. A receiver receives the communicated tire pressure information from each tire pressure monitoring device. A processor circuit, associated with the receiver, determines if the communicated tire pressure information from at least one of the tire pressure monitoring devices is significantly less than a tire pressure determined to be safe for vehicle operation and, if so, to generate a warning signal. A body control module, upon receiving the warning signal, automatically activates the hazard lights without driver input.Type: GrantFiled: August 14, 2015Date of Patent: August 22, 2017Assignee: Continental Automotive Systems, Inc.Inventors: David Cruz Mendez, Ernesto Amezcua Maciel, Ignacio Padilla Rabadan, Carlos Alfonso Rodriguez Gomez

Patent number: 9367711Abstract: Embodiments of the present invention provide RFID systems having battery-assisted, Semi-Passive RFID tags that operate with sensitive transistor based square law tag receivers utilizing a plurality of tag receiver dynamic range states. Embodiments of the present invention are also enhanced with receiver training and synchronizing methods suited to the high tag sensitivity and need for dynamic range state switching. These enhancements may employ pseudo-random sequence based receiver training, activation signaling, and frame synchronizing. Further enhancement is achieved via design of system command sets and tag state machine behavior that control system interference and allow maximum usage of high sensitivity. Command set design also allows for convenient expansion to active transmitters and receivers in tags operating within the same system.Type: GrantFiled: September 4, 2008Date of Patent: June 14, 2016Assignee: Intelleflex CorporationInventors: Farron Dacus, Joseph Bouchez, Johannes Albertus van Niekerk, Alfonso Rodriguez
