摘要:
A user, such as a clinician or the patient, uses a control device to manipulate at least one neurostimulation parameter. A mapping system uses a calibrated map to map the directional output of the control device to values of at least one stimulation parameter to allow the user to intuitively control the value of the parameter. In some embodiments, where a stimulation device is used to deliver spinal cord stimulation (SCS) therapy for example, the user manipulates a parameter to effect the location and/or strength of paresthesia experienced by the patient. In exemplary embodiments, the parameter values are combinations of electrodes, and the mapping system selects electrode combinations based on the output of the control device such that a direction of movement of paresthesia experienced by the patient corresponds to a direction of manipulation of a directional controller of the control device. The mapping system may calibrate the map based on patient paresthesia information received from a user.

Signal characteristics, or signatures, defined by one or more forms of energy being transferred during the commission of an activity are captured in dimensionally-reduced numerical sequences. Dimensionality reduction is achieved such that reduced data acquired during a detection phase can be directly compared with such reduced data produced during system training. Activities, events, human identities and so on can be identified through such direct comparison. Dimensionality reduction, such as through sparse approximation or simultaneous sparse approximation, may produce combinations of scaled prototype functions. Such combinations or their parametric representations compactly describe the signal characteristics for purposes of discovering new activity signatures, of extracting test signals from a set of measurements and of comparing sets for purposes of detection and classification.

A system and method are provided for automatically correlating neurological activity to a predetermined physiological response. The system includes at least one sensor operable to sense signals indicative of the neurological activity, and a processing engine coupled to the sensor. The processing engine is operable in a first system mode to execute a simultaneous sparse approximation jointly upon a group of signals sensed by the sensor to generate signature information corresponding to the predetermined physiological response. The system further includes a detector coupled to the sensors, which is operable in a second system mode to monitor the sensed signals. The detector generates upon selective detection according to the signature information a control signal for actuating a control action according to the predetermined physiological response.

A programming device compares filter information to information that describes possible combinations of the electrodes within an electrode set implanted in a patient. The filter information describes at least one characteristic of valid, e.g., desired, electrode combinations, and in exemplary embodiments, is received from a user, e.g., a clinician, via a user interface of the programming device. The filter information can describe a number of electrodes in valid combinations, a fixed polarity for an electrode for valid combinations, or relational characteristics of the electrodes of valid combinations. The comparison process may be iterative. The programming device identifies a subset of the possible electrode combinations based on the comparison. By identifying the valid subset of electrode combinations based on the filter information, the programming device may reduce the amount of clinician and patient time required to program an implantable neurostimulator.
摘要:
A method and system are provided for parallactically synced acquisition of images about a common target from mutually displaced imaging positions. At least first and second imaging devices are disposed respectively at first and second imaging positions. The first imaging device is actuated to acquire a first image with a target of interest disposed at a predetermined relative position within a field of view thereof. The second imaging device is actuated to acquire a second image with the target of interest disposed within a field of view thereof. A target feature finder is executed in a processor to detect the target of interest within the second image. A plurality of user prompts are generated at the second imaging device responsive to detection of the target of interest in the second image. The user prompts include: visual indicia adaptively applied to the second image to visually distinguish the target of interest, and orientation correction alerts adaptively generated to guide angular displacement of the second imaging device to situate the target of interest at the predetermined relative position within its field of view.

A system and method are provided for distinguishing biota, such as insect types, from overall images, images of their wings or of other body parts. The system and method exploit various techniques described herein, in combination with large scale capture of sample imagery to achieve a flexible mechanism for automated classification on biota of any type.

An inspection apparatus determines information indicative of structure that may be hidden behind an obscuring boundary, such as a wall. A processor collects measurements of properties characterizing the hidden structure and measurements of location of the apparatus. The collected data are mapped to produce an image of intensity in the characteristic measurements. Each intensity value in the image reflects a measure of density, of material type, or of some other specific information by which hidden structure can be discerned. The intensity changes indicating the hidden structure are displayed to a user via color-coded pixels or the like.

摘要:
A distributed system comprises a programming device and a remotely located server. During a programming session, the programming device transmits programs and rating information associated with the programs to the server. The server presents the rating information to a clinician to assist the clinician in selecting from among programs tested during the programming session. The programming device may also transmit patient information and device configuration information to the server for storage with selected programs and rating information within a database as part of a patient record. Programs and information received from a plurality of programming devices and for a plurality of patients may be stored in the database and analyzed by the server to provide responses to user queries made by clinicians via programming devices.
