  • Patent number: 11109763
    Abstract: A photoacoustic catheter includes an elongated catheter body and a housing positioned near a distal end of the elongated catheter body. A length of multimode fiber extends through the elongated catheter body and has a distal end that is beveled at about 45° relative to a longitudinal axis of the multimode fiber and is positioned in the housing. An ultrasonic transducer, electrically connected to an electrical wire extending along the elongated catheter body, is positioned within the housing. A mirror element is also positioned within the housing and includes a mirror surface beveled at about 45° relative to the longitudinal axis of the multimode fiber. The catheter is operable to deliver an optical wave through the multimode fiber and to deliver an ultrasonic wave collinearly from the housing and out of an aperture of the housing to obtain optical data and ultrasonic data within a mammalian luminal organ.

  • Publication number: 20210226712
    Abstract: User equipment (UE) can include a spectrum analyzer to monitor characteristics of transmission channels. The user equipment can monitor a 600 MHz spectrum and associated channels, for example, to determine if the spectrum is free of interference or is currently occupied. The UE can analyze a received signal strength indication (RSSI), a reference signal received power (RSRP), a reference signal received quality (RSRQ), and signal-to-interference-plus-noise ratio (SINR), for example, to distinguish between types of interference if a channel is occupied. User equipment (UE) can aggregate data and report such data to a network device further aggregate the data and to generate reports. Network components can be deployed or optimized based at least in part on network metrics provided by individual UEs or aggregated data provided by a plurality of UEs. In some instances, the UE can be a mobile phone of a customer to gather metrics in a distributed manner.

  • Patent number: 11013933
    Abstract: Methicillin-resistant Staphylococcus aureus (MRSA) possesses array of strategies to evade antibiotics through mutational inactivation, hiding inside host immune cells or concealing inside the biofilm in a sessile form. We report a drug-free approach to eradicate MRSA through blue-light bleaching of staphyloxanthin (STX), an anti-oxidative carotenoid residing inside the cell membrane of S. aureus. The photobleaching process, uncovered through a transient absorption imaging study and quantitated by mass spectrometry, decomposes STX and sensitizes MRSA to reactive oxygen species attack. Consequently, photobleaching using low-level blue light exhibits high-level synergy when combined with low-concentration of hydrogen peroxide. Antimicrobial effectiveness of this synergistic therapy is validated in MRSA culture, MRSA-infected macrophage cells, biofilm, and a mouse wound infection model. Collectively, these findings highlight broad applications of STX photobleaching for MRSA-infected diseases.

  • Patent number: 10952091
    Abstract: The techniques described herein involve analysis of communication data included in trace file(s) of device(s) involved in a communication. These trace file(s) may each include data associated with multiple layers of a communication protocol stack of a respective device or data associated with a single such layer. The techniques may further involve one or more of determination of performance metrics associated with data at a specific layer of a specific device, correlation of the data between layers of a device, or correlation of data across multiple device(s) involved in the communication. The performance metrics or correlated data may then be analyzed based on thresholds or models to determine whether the performance metrics or correlated data exhibits a degraded quality of user experience. Also or instead, graphic or textual representations of the performance metrics or correlated data may be generated.

  • Publication number: 20210073702
    Abstract: A processor-implemented method includes receiving, from a mobile device, transmission information corresponding to an audio data transmission associated with an audio data packet loss of one or more audio data packets. The processor determines, based at least in part on the transmission information, a geographic region associated with a wireless communication network transceiver. The processor further determines an average audio data packet loss rate associated with the geographic region and a correlation between the audio data packet loss and at least one key performance indicator (KPI). The KPI is indicative of the audio data transmission. Based at least in part on (i) the average audio data packet loss rate and (ii) the correlation between the audio data packet loss and the at least one KPI, the processor generates a handover instruction comprising at least one threshold value for transitioning control from a first cell channel to a second cell channel.

  • Patent number: 10827168
    Abstract: This disclosure describes techniques for capturing radio frequency (RF) signal over the air, processing spectrum power data, and uploading data to a central data repository for analysis and reporting. Captured RF signals are filtered and amplified via a front-end module of a probe that includes a filter and a low noise amplifier (LNA). Output signals can be decoded into digital TV metadata and image captures via a TV tuner and spectrum power, and then analyzed via a software defined radio (SDR). Digital TV metadata and images, as well as SDR data, can be uploaded and collected at a server. The server processes collected spectrum data from SDR into spectrum reports. The server can also analyze collected digital TV metadata to identify with increased accuracy RF sources originating from transmitting TV facilities.

  • Publication number: 20200306295
    Abstract: Confronted with the rapid evolution and dissemination of antibiotic resistance, there is an urgent need to develop alternative treatment strategies for drug-resistant S. aureus, especially for methicillin-resistant S. aureus (MRSA). We report a photonic approach to eradicate MRSA through blue-light photolysis of staphyloxanthin (STX), an anti-oxidative carotenoid acting as the constituent lipid of the functional membrane microdomains of S. aureus. Our transient absorption imaging study and mass spectrometry unveil the photolysis process of STX. After effective STX photolysis by pulsed laser, cell membranes are found severely disorganized and malfunctioned to defense antibiotics, as unveiled by membrane permeabilization, membrane fluidification, and detachment of membrane protein, PBP2a.

  • Publication number: 20200267588
    Abstract: The techniques described herein involve determining a context-based Quality of Experience based upon client device Quality of Experience diagnostic files in combination with client device equipment dynamics. Client device Quality of Experience (QoE) diagnostic files may indicate a reduced QoE at a client device, such as reduced signal strength or an increased number of dropped packets. User behavior during a reduced QoE event may be reflected as equipment dynamics, which may be included in equipment dynamics files. A service provider may receive information from the client device and may analyze the information to determine, with an increased confidence level, that the user device experiences a reduced QoE. Network resources may be allocated in response to the reduced QoE determination, thereby increasing a functioning of the computing network and an associated device's Quality of Experience.

  • Publication number: 20200260218
    Abstract: Techniques directed to utilizing networked devices to enhance user experience are described. In an example, sensor data received from sensor(s) associated with a facility can be used to determine a presence of a user equipment (UE) within or proximate to the facility. Based at least in part on the sensor data, an account associated with the UE can be accessed. Based at least in part on account data associated with the account, a distribution of network technology can be modified to temporarily enable the UE to access a service that is not otherwise available to at least one other UE within or proximate to the facility.
