There is provided a method for monitoring interaction with 3D medical images, comprising: dividing the 3D image into a sequence of a 2D images, arranging the sequence into slabs each including at least one 2D image, computing, for each respective slab, a minimal amount of viewing time a user is predicted to spend viewing the respective slab, monitoring, while the 3D medical image is presented on a display, an amount of time a user actually spent viewing portions of the 3D medical image corresponding to each of the of slabs, in response to the amount of time spent viewing a certain portion of the 3D medical image being less than the computed minimal amount of viewing time of a certain slab corresponding to the certain portion, generating instructions for implementation by a user interface indicative of the amount of time spent being less than the computed minimal amount of time.

There is provided a system and a method of generating an annotated structured dataset, comprising: receiving a medical classification term, searching over the unstructured patient data for extracting unclassified unstructured text fragments, presenting a subset of the unclassified unstructured text fragments, receiving an indication of a selection of none or at least one of the text fragments, and one of: (i) classifying non-selected unclassified unstructured text fragments according to the medical classification term, and classifying selected text fragments as not satisfying the medical classification term, and (ii) classifying selected unclassified unstructured text fragments according to the medical classification term, and classifying non-selected unclassified unstructured text fragments as not satisfying the medical classification term, and iterating the searching, and/or the presenting, until no text fragments are obtained by the search, wherein the annotated structured dataset is created by the classification of unclassified unstructured text fragments into the medical classification term.
摘要:
There is provided a computer implemented method of authenticating a user, comprising: receiving a sequence of key-related events of a manually typed text by a user using a keyboard, extracting a plurality of sub-features from the sequence of key-related events, for each instance of a plurality of instances of a respective n-gram of a plurality of n-grams extracted from the text, computing a plurality of statistical features for each respective n-gram from the plurality of sub-features extracted for the plurality of instances of the respective n-grams, feeding the plurality of statistical features computed for each of the plurality of n-grams into a trained machine learning (ML) model, and triggering a security process when the ML model outputs an indication of non-authentication of the user.
摘要:
A computer implemented method of routing a verbal input to one of a plurality of handlers, comprising using one or more processors adapted to execute a code, the code is adapted for receiving a verbal input from a user, applying a plurality of verbal content identifiers to the verbal input, each of the verbal content identifiers is adapted to evaluate an association of the verbal input with a respective one of a plurality of handlers by computing a match confidence value for one or more features, such as an intent expressed by the user and/or an entity indicated by the user, extracted from the verbal input and routing the verbal input to a selected one of the handlers based on the matching confidence value computed by the plurality of verbal content identifiers. The selected handler is adapted to initiate one or more actions in response to the verbal input.
摘要:
A system and a device for enabling a plurality of hardware memory components to be installed on a computational device, in which the hardware components are isolated from each other and/or from the remainder of the computational device. Such “insulation” can optionally be used in order to provide security for the information stored on the hardware memory component. For example, one such component could optionally have access blocked when the computational device is connected to a network such as the Internet, in order to prevent an external, unauthorized user from gaining access to the information stored on such a hardware memory component. One possible application of the present invention is for security of operation of a computational device.
摘要:
Using surface microwaves for measuring and determining density and/or moisture content of a material. Positioning material within a proximate free space region spanning immediately above surface of a surface microwave waveguide, the surface microwave waveguide includes an electrically conducting rectangular block and a dielectric rectangular insert element compactly fitting into the block. Transmitting microwaves into the first end of the surface microwave waveguide, a first portion of the transmitted microwaves propagate within the surface microwave waveguide and a second portion propagates within the proximate free space region including the material. Parameters (amplitude, phase, attenuation, and phase shift) of the propagating microwaves are perturbed by the material and are a function of density and/or moisture content of the material. Receiving the portions of propagating microwaves exiting the surface microwave waveguide, whereby the parameters of the transmitted and received microwaves are useable for determining density and/or moisture content of the material.
摘要:
A method of expanding/maintaining undifferentiated hemopoietic stem cells or progenitor cells by obtaining undifferentiated hemopoietic stem cells or progenitor cells; and either seeding the undifferentiated hemopoietic stem cells or progenitor cells into a stationary phase plug-flow bioreactor in which a three-dimensional stromal cell culture has been pre-established on a substrate in the form of a sheet, the substrate including a non-woven fibrous matrix forming a physiologically acceptable three-dimensional network of fibers, thereby expanding/maintaining undifferentiated hemopoietic stem cells or progenitor cells, or culturing the undifferentiated hemopoietic stem cells or progenitor cells in conditioned medium obtained from such a reactor.
摘要:
An optical transducer includes a housing containing a light source and a light detector laterally spaced from the light source; and a deformable membrane mounted over the light source and light detector such that an inner surface of the membrane reflects light from the light source to the light detector to produce, from the light detector, an output electrical signal modulated in accordance with the deformations of the membrane. The inner surface of the membrane has a small central region of high light reflectivity to maximize the output electrical signal produced by the deformations of the membrane, and a large outer region of lower light reflectivity to minimize noise in the output electrical signal produced by multi-reflection of light from the light source to the light detector. The membrane is preferably formed in its outer region with circular corrugations coaxial with each other and with the central region of high light reflectivity to increase the deformability of the central region.
