  • Publication number: 20230296524
    Abstract: A system for automated collection of Raman spectra from ex-vivo tissue samples is provided. The system may comprise a cartesian robot that moves a detachable Raman probe to points on the ex-vivo tissue sample that have been predetermined through a 3D image of the sample. Accordingly, methods of rapid acquisition of multiple Raman spectra from a heterogeneous tissue sample are provided. The inventive methods consider variable contours of the sample to provide Raman spectra from multiple points while generating optimal coverage of the sample. The inventive methods include cleaning the Raman probe between acquisitions of Raman spectra from the multiple points.

    Abstract: Provided are Raman systems and methods for detection of cancerous tissues in tumor margins in real time during surgical procedures. The systems include a laser excitation source, a probe, a spectrometer and a camera specifically designed for use of Raman spectroscopy in real time during surgery. The inventive methods pertain to quality assessment of Raman data, comparison of obtained Raman data against known biomarkers and classification of tissue as cancerous or non-cancerous on the basis of corresponding Raman data. The systems and methods allow for previously unavailable detection and classification of tissue with Raman spectroscopy in real time surgical applications, including the identification of cancer sub-types.

  • Publication number: 20180358012
    Abstract: Embodiments are directed to systems, methods, and devices for providing help to a user through an output modality. Embodiments include an analysis logic implemented at least partially in hardware to receive an indication to provide help or other information to the user; identify an availability of one or more output modalities for providing the help; and determine an output modality for providing the help based on the availability of the one or more output modalities. Embodiments also include a dialog system implemented at least partially in hardware to process the request for help; and provide a dialog message in response to the request for help, the dialog message provided on the determined output modality. Some embodiments also include a sensor input for receiving sensory information, wherein the analysis logic identifies the output modality based, at least in part, on the sensory information.

  • Publication number: 20120071767
    Abstract: A pulmonary artery pressure estimator attaches a plurality of acoustic sensors to a patient so as to measure a second heart sound. The sensors are arranged so that an A2 component of the second heart sound is maximized from at least one of the sensors and a P2 component is maximized from at least another one of the sensors. Electrodes are also attached to the patient so as to measure a cardiac interval. A splitting interval is derived from the A2 and P2 components, which is normalized by the cardiac interval. The normalized splitting interval provides an estimation of the pulmonary artery pressure (PAP).

  • Patent number: 6987738
    Abstract: A method of performing packet level transmission scheduling in a communications systems including a plurality of cells, each cell including a base station and plurarity of mobile stations. The method performs scheduling while considering radio resource allocation at the wireless access node. In a schedule plan phase of the method, average power and average effective data rate are determined for all mobile stations in the system. In addition, the planned fractions of frames ? that each mobile in the system will transmit is determined so that resources are allocated fairly. In the actual schedule phase of the method, current power and effective data rate values are compared to the average power values. This information along with the ? values is used to determine the actual schedule of packet transmissions for all mobiles in a particular cell.
