20090035356 | MODIFIED BIODEGRADABLE POLYMERS, PREPARATION AND USE THEREOF FOR MAKING BIOMATERIALS AND DRESSINGS - The invention concerns a method for preparing a modified biodegradable polymer in aqueous medium comprising at least two steps. The first step is a reaction between an amino acid, a peptide or a polypeptide and maleic anhydride to form a compound having an unsaturated vinyl-carboxylic acid function. In the second reaction step, the unsaturated diacid obtained in the first step is reacted with a biodegradable polymer having at least one primary amine function, such as a fibrous protein or a glycosaminoglycan. The preferred polymer used is collagen or chitosan. The invention also concerns the modified biodegradable polymer obtained by the method. The invention further concerns a biomaterial or a dressing containing the modified biodegradable polymer having biocompatible, cytocompatible, hemostatic, bactericidal and wound healing properties, and its medical, biomedical, pharmaceutical or cosmetic use. | 02-05-2009 |

20110258544 | SYSTEM AND METHOD FOR SUGGESTING AUTOMATED ASSISTANTS BASED ON A SIMILARITY VECTOR IN A GRAPHICAL USER INTERFACE FOR MANAGING COMMUNICATION SESSIONS - Disclosed herein are systems, methods, and non-transitory computer-readable storage media for suggesting and inserting automated assistants in a graphical user interface for managing communication sessions. A system for suggesting an automated assistant generates a first vector describing a current context of a current communication session, and generates a comparison of the first vector and a second vector associated with a past context of an automated assistant in a past communication session. Then, if the comparison exceeds a similarity threshold, the system suggests the automated assistant to at least one user in the current communication session. Optionally, the system can predictively insert the automated assistant in a communication session if the comparison exceeds a similarity threshold. The graphical user interface for managing communication sessions displays automated assistants in a same manner as human participants. | 10-20-2011 |
20110258550 | SYSTEM AND METHOD FOR GENERATING PERSISTENT SESSIONS IN A GRAPHICAL INTERFACE FOR MANAGING COMMUNICATION SESSIONS - Disclosed herein are systems, methods, and non-transitory computer-readable storage media for generating persistent sessions in a graphical user interface for managing communication sessions. A system configured to practice the method tracks interactions of a user with an automated assistant in a communication session displayed in a graphical user interface for managing communication sessions, wherein the graphical user interface displays automated assistants in a same manner as human participants. The system identifies work product produced by the interactions, associates the work product with the user, and saves the work product in a persistent communication session. The system can load work product by identifying a user in the current communication session and a current context. The system retrieves and restores the stored work product in the current communication session. The stored work product can include at least one setting associated with an automated assistant. | 10-20-2011 |
20110296312 | USER INTERFACE FOR MANAGING COMMUNICATION SESSIONS - Disclosed herein are systems, methods, and non-transitory computer-readable storage media for displaying a user interface for managing communication sessions on a communication device. A system configured to practice the method displays, on a first side portion of the user interface, a first set of user-configurable communication information. The system displays, a second side portion of the user interface, a second set of user-configurable communication information. The system displays, on a center portion of the user interface, a communication work space for managing communication sessions. In one embodiment including a touch sensitive display, this interface is used with a tablet device such that a natural position of user's thumbs are in an optimal position to interact efficiently with the user interface. The side portions can be user-configurable to display, for example, contacts, calendar events, tasks, memos, and so forth. | 12-01-2011 |

20140107501 | WIRELESS MULTI-SENSOR PLATFORM FOR CONTINUOUS REAL-TIME MONITORING OF CARDIOVASCULAR RESPIRATORY DYNAMICS - A set of vectorcardiogram leads attach to a patient and a signal conditioning circuit receives a plurality of analog signals from the plurality of vectorcardiogram leads. An analog to digital converter that transforms the conditioned analog signals into digital signals and a processor transforms the digital vectorcardiogram signals into electrocardiogram signals. | 04-17-2014 |
20140180036 | DEVICE AND METHOD FOR PREDICTING AND PREVENTING OBSTRUCTIVE SLEEP APNEA (OSA) EPISODES - A wireless sleep apnea treatment system comprises a garment having at least one ECG monitor, a wireless signal acquisition board in communication with the ECG monitor and the computer and providing the electrical reading from the ECG monitor to the computer, and a patient stimulator controlled by the computer through the wireless signal acquisition board. | 06-26-2014 |
20140207005 | SYSTEM AND METHOD FOR REAL-TIME THREE DIMENSIONAL MODELING OF CARDIOVASCULAR DYNAMICS AND THE HEART USING ELECTROCARDIOGRAM SIGNALS - There is taught herein a real-time, lumped parameter cardiovascular dynamics model that uses features extracted from online electrocardiogram (ECG) signal recordings to generate certain surrogate hemodynamic signals. The derived signals can be used to real time animate a 3-D heart model. The model represents the coupled dynamics of the heart chambers, valves, and pulmonary and systemic blood circulation loops in the form of nonlinear differential equations. The features extracted from ECG signals can be used to estimate the timings and amplitudes of the atrioventricular activation input functions as well as other model parameters that capture the effect of cardiac morphological and physiological characteristics. The results indicate the potential of a virtual instrument that uses the model-derived signals for clinical diagnosis in lieu of expensive instrumentation. | 07-24-2014 |
