20130198590METHOD OF REDUCING PEAK-TO-AVERAGE POWER RATIO, CUBIC METRIC AND BLOCK ERROR RATE IN OFDM SYSTEMS USING NETWORK CODING - Disclosed in a novel scheme to jointly reduce and trade-off Peak-to-Average Power Ratio (PAPR) and a Block Error Rate (BLER) using random network coding. To do this, the different representations of the input information block are generated using a special form of network coding matrices. Further, the encoded block puncturing is utilized to improve in the PAPR against a degradation in the BLER.08-01-2013

20150216426METHOD AND SYSTEM FOR CHARACTERIZING CARDIOVASCULAR SYSTEMS FROM SINGLE CHANNEL DATA - Methods to identify and risk stratify disease states, cardiac structural defects, functional cardiac deficiencies induced by teratogens and other toxic agents, pathological substrates, conduction delays and defects, and ejection fraction using single channel biological data obtained from the subject. A modified Matching Pursuit (MP) algorithm may be used to find a noiseless model of the data that is sparse and does not assume periodicity of the signal. After the model is derived, various metrics and subspaces are extracted to characterize the cardiac system. In another method, space-time domain is divided into a number of regions (which is largely determined by the signal length), the density of the signal is computed in each region and input to a learning algorithm to associate them to the desired cardiac dysfunction indicator target.08-06-2015

20130096394SYSTEM AND METHOD FOR EVALUATING AN ELECTROPHYSIOLOGICAL SIGNAL - A method of evaluating an electrophysiological signal is disclosed. A mathematical reconstruction over at least one cycle of the electrophysiological signal is used to identify an abnormal substrate. A non-transitory computer readable medium is also disclosed. The nontransitory computer readable medium has stored thereon instructions for identifying a pathological substrate from a mathematical reconstruction of an electrophysiological signal, which, when executed by a processor, causes the processor to perform steps comprising using a mathematical reconstruction over many cycles of the electrophysiological signal to identify a pathological state. A system for evaluating an electrophysiological signal includes a processor configured to identify a pathological condition from a mathematical reconstruction of the electrophysiological signal. The system also includes a data input coupled to the processor and configured to provide the processor with the electrophysiological signal. The system further includes a user interface coupled to either the processor or the data input.04-18-2013

20090294313SINGLE-USE MEDICAL EQUIPMENT PACKAGE COVER - A single-use medical equipment package cover comprising a solid preformed shell to cover the functional part of a medical instrument or surgical device and a trailing soft plastic cover or plastic sheath for the rest of the surface of the medical instrument or surgical device. The medical equipment package cover is applied in a folded or stowed configuration and is then unfolded to a deployed configuration. The trailing plastic cover may be transparent and removably affixable to a lens surface or a monitor surface. Unfolding of the removably affixed sheath imparts an interpersonal barrier to block aerial or sputum transfer between patient and medical personnel operating medical equipment being deployed on and within the patient.12-03-2009
20100261967VIDEO LARYNGOSCOPE SYSTEM AND DEVICES - An embodiment encompassing reusable video laryngoscopes that are insertable into transparent or non-transparent disposable sheaths having clear optically clear viewing windows that receive contact with camera lens. The reusable video laryngoscopes are configured to be detachably secured by locking tabs located in the transparent or non-transparent disposable sheaths with complementary shaped posts and ledges of the video laryngoscopes. The video laryngoscopes that are secured into the transparent or non-transparent disposable sheaths may be inserted into the patient's mouth to provide clear camera viewing through the optically clear window ports of the transparent or non-transparent disposable sheaths to allow endotracheal procedures to be undertaken. The transparent or non-transparent disposable sheaths are sterilizable and may be used just once for a given patient. The video laryngoscopes in the form of a baton are detachably removeable from the disposable sheath exposed to a patient.10-14-2010
20110178372CHANNEL LARYNGOSCOPES AND SYSTEMS - Video-based laryngoscopes having an external centrally located channel coursing from the handle to a curved blade configured to deliver an ETT to a trachea as visualized by a non-removable, or alternatively, a removable video camera and lighting unit located beneath the external channel. The channel laryngoscope may be made for single use in a patient and discarded, or be processed for re-use. Alternatively, the channel laryngoscope may have a removable video camera and lighting member located within an internal chamber that runs parallel with the external channel. In another embodiment a laryngoscope adapter may be detachably affixable to the channel laryngoscope equipped with the non-removable camera to provide a decontaminated or sterile surface to permit re-use of the channel laryngoscope without having to undergo washing or decontamination procedures.07-21-2011
20110178373TELEMEDICINE SYSTEMS AND METHODS - Methods and systems for telemedicine are provided. A method for operating a telemedicine base unit includes initiating a remote connection with a remote care site. The remote care site may be selected from a plurality of remote care sites based on an attached medical device. The telemedicine base unit transmits the output from the attached medical device to the remote care site. Medical device operating instructions and other information are received from the remote care site. The medical device operation instructions provide guidance for operating the attached medical device.07-21-2011
20140179998VIDEO RETRACTOR - A retractor includes a handle portion, a blade portion coupled to the handle portion. The blade portion is configured for insertion into an internal region of a patient. The blade portion includes a first portion configured to manipulate tissue of the patient. In an embodiment, a locator element is configured to highlight an external region of the patient to indicate to a user the location of the first portion in the internal region. In an embodiment, a signal-transmission medium is coupled to the blade portion and has a port. An overmolded camera unit has a lens and is configured to couple with the port. When the camera unit is coupled with the port, the lens is oriented to capture images of the internal region.06-26-2014
