Abstract: A method includes, during arrhythmia occurrence, acquiring multiple sets of reference coronary sinus electrophysiological (CS-EP) signals with a first catheter in coronary sinus (CS) of a heart of a patient, while measuring multiple respective reference CS locations of the first catheter. One or more intra-cardiac electrophysiological (IC-EP) signals are acquired with a second catheter located in a cardiac chamber of the heart, while acquiring actual CS-EP signal with first catheter, and while measuring an actual CS location of first catheter. Using reference CS locations, reference CS-EP signal is identified whose reference CS location is nearest to actual CS location of the first catheter. A signal-stability measure between actual CS-EP signal and identified reference CS-EP signal is estimated.

Abstract: Embodiments may be directed to lens cameras which may be cameras arranged as a sensor in a lens cap. A lens camera may comprise a printed circuit board with a digital image sensor and associated components enclosed in a cylindrical body that may be constructed of metal, plastic, or the like, or combination thereof. Lens cameras may be fitted with lens mounts for attaching host devices, cameras, interchangeable lens, or the like. Lens mounts on a lens camera may be arranged to be compatible with one or more standard lens mounts. Accordingly, a lens camera may be attached to cameras that have compatible lens mounts. Also, interchangeable lens having lens mounts compatible with the lens camera may be attached to the lens camera. Further, lens cameras may communicate with host devices using wired or wireless communication facilities.

Abstract: A video encoder with an integrated temporal filter, which has an output carrying a sequence of encoded frames, includes: an input receiving input frame data; a temporal filter receiving the input frame data from the input and producing filtered frame data; motion processing modules receiving reconstructed frames derived from the sequence of encoded frames and the filtered frame data from the temporal filter and producing a residual error signal output; and a coder module which receives the input frame data and the residual error signal and produces the sequence of encoded frames.

Abstract: Embodiments are directed towards modifying a quality of an image without affecting a bit rate associated with a video sequence of images. For each macro-block (MB) or sub-block within a MB for a target image to be encoded, various statistics are determined for a luminance component and chrominance components that provide at least average values for the chrominance components that may then be used to identify saturation thresholds. The saturation thresholds are used to determine a Qlevel. An average Qlevel from at least a previous frame is used to generate a Q modulation factor that may be combined with an activity based modulation factor and/or variance based modulation factor, or used singly. The final quantizer is calculated by bit-rate controller base quantizer multiplied by the Q modulation factor, and may be used to encode a MB or sub-block within a MB.

Abstract: A computer-implemented method for providing patient information during surgery is presented. The method includes activating a camera configured to be worn on a user's head in response to input from the user and receiving from the camera a first image of a visual identifier associated with a patient. The method also includes processing, at a processor configured to be worn on the user's head, the image to determine a unique patient identifier encoded in the visual identifier and retrieving medical information associated with the unique patient identifier from a centralized information source that includes a patient record containing the medical information. The medical information associated with the unique patient identifier is presented on a display configured to be worn on the user's head and confirmation of the medical information is received from the user.

Abstract: Among other things, a computer implemented method for monitoring patients released from an intensive care unit in a healthcare environment is described. The method comprises receiving medical information of a patient located at a location different from the intensive care unit, evaluating conditions of the patient by applying one or more rules to the medical information of the patient, and sending a message to the intensive care unit when the conditions of the patient match the one or more rules.

Abstract: A system and method for automatically removing polarized light in an environment having polarized light and unpolarized light. Light is processed by a polarizer and measured by a sensor. Multiple measurements of a light characteristic are taken, each measurement corresponding to a polarity setting of the polarizer. The polarizer is automatically adjusted to enable the multiple measurements. The measurements may be of average light intensity, contrast, saturation, or another characteristic. Based on the multiple measurements and the corresponding polarity settings, an optimal polarity setting is determined, such that the amount of polarized light is minimized. A curve fitting calculation may be used to make the determination. The polarizer is adjusted to the determined polarity setting.

Abstract: Among other things, a computer implemented method includes receiving a unique patient identifier for a patient. The method also includes using the unique patient identifier to retrieve medical information associated with the patient from a centralized information source that includes a patient record containing the medical information. After performing a medical procedure on the patient based on the retrieved medical information, the method includes updating the patient record in the centralized information source to reflect the performed medical procedure.

Abstract: Among other things, a computer implemented method for use in a healthcare environment is described herein. The method comprises documenting a set of medical data of a patient in a data repository based on an identifier assigned to the patient, wherein the set of medical data is provided from a medical data source; managing medical information represented by the set of medical data using a computer system in communication with the data repository; and based upon a received request, providing a portion of the documented set of medical data from the data repository to medical equipment remotely located from the data repository, wherein receipt of the request is based upon the identifier assigned to the patient.
