Abstract: Architecture for providing communications resources of a network for client intercommunications. A client that desires to communicate makes a request to an arbitrary communications server node by the announcing of identifying information. The web service “parks” the request until the identifying information is ready. A second client can ultimately interact with the first client by sending identifying information and following the same lookup path to find the location at which the first client request is “parked”. A continuous hash is employed that enables a client to negotiate services of a resource and via which resource multiple clients can rendezvous for communications. The continuous hash minimizes the disruption to clients already accessing network resources. A resource is brought online or taken offline without dramatically impacting ongoing use of currently operational resources. In the event a hosting resource fails, the clients repeat the lookup process and re-converge on a new server.

Abstract: Architecture that provides real-time opportunistic access to data that is relevant and/or related user activities. Ways are disclosed to use information of a single workspace to structure automatic searches into a number of data stores in order to opportunistically extract relevant information therefrom. An email client can use workspace content to train a filter for identifying new messages deemed relevant or related to the content and topics of the workspace, a system can be provided to use the content of a single web site as contextual data for providing auto-generated links to other sites within the corporate enterprise, a collaborative application can natively understand the content being shared and then look for specific terms in the content which can be employed for generating a search query and returning relevant and/or related data, and combinations thereof are provided for automatically generating and searching data stores for relevant and related information.

Abstract: An internally insulated exhaust aftertreatment device with a converter body, an end cone assembly and a sealing device inserted in an annular area between the external shell and the substrate of the converter body. The sealing device is sealingly engaged between an inner end cone and the insulating material. The sealing device comprises a wire-mesh ring-shaped device conformable to the annulus between the substrate and the shell, and may have a substantially round cross-sectional area, a C-shaped cross-sectional area, or an L-shaped cross-sectional area.

Abstract: A method, system, and architecture for providing a web conference system that efficiently provides a breakout room or multiple breakout rooms within a single web conference (also referred to herein interchangeably as a “meeting” or “virtual meeting”) is provided. In some embodiments, the web conference system architecture provides a web conference system that allows for the creation of breakout rooms within a single web conference, where each breakout room provides a named view onto each feature subsystem of the web conference, with or without separate permission levels on each view. Each breakout room may also provide a named view of the contents of the web conference, with or without separate permission levels on each view.

Abstract: A method and apparatus for calculating and monitoring the impedance of an implanted pacemaker lead, and in particular to such a method and apparatus for monitoring the impedance to determine whether a lead fault, such as a lead rupture or a lead dislocation, has occurred. In order to avoid reprogramming the implanted pacemaker to deliver a pulse having known parameters in order to permit an impedance measurement to be made, the method and apparatus operate on the basis of the system formed by the pulse generator, the electrode leads and body tissue being considered to behave as an RC circuit, with the pulse generator emitting an ideal square wave pulse which then exhibits an exponential decay in the body tissue having a decay time constant associated therewith. From surface ECG measurements, the decay time constant is estimated, and since the capacitance of the pulse generator is known, the lead impedance can then be calculated.

Abstract: A compact, power-sparing detector for detecting heart polarizations is described. The detector has a first operational amplifier which uses sensed heart signals from a heart as an input signal. By means of feedback coupling via a second operational amplifier, a resistor and a capacitor, the system strives to achieve a minimum voltage gradient across the input terminals of the first operational amplifier. When an electrical signal with a signal slope corresponding to a heart depolarization arrives at the input terminal of the first operational amplifier, the second operational amplifier is no longer able to damp the input signal, and a peak output signal is sent from the first operational amplifier to each of a first comparator and a second comparator, respectively.

Abstract: An implantable defibrillator has a capacitor which, through a controllable switch arrangement, can either be connected to a voltage source for charging the capacitor, or connected across electrodes placed at the heart for delivering a defibrillation pulse. To calculate the minimum pulse energy required for successful defibrillation, ventricular fibrillation is first induced, so that a plurality of defibrillation attempts, with energy increasing from attempt-to-attempt can be undertaken until successful defibrillation occurs. For inducing ventricular fibrillation, the capacitor of the implantable defibrillator is connected to the voltage source until a prescribed charging voltage, which is significantly below the voltage necessary for defibrillation, is reached, and subsequently, the capacitor is disconnected from the voltage source during brief time spans at intervals within the framework of a sequence and is connected during those time spans to the electrodes.

Abstract: A method and apparatus for detecting a sequence of abnormal events in an electrical signal, such as the depolarization signal of the heart, compares a selective signal parameter to a defined threshold, and measures the maximum value of the signal parameter for each event which exceeds the threshold. The characteristic quantity corresponding to the statistical distribution of the respective maximum values for a defined number of most recently, successively occurring events is calculated, with each newly measured maximum value causing the characteristic quality to be updated. The characteristic quality is compared in a comparator to a defined rated value, and a signal indicating the presence of a sequence of abnormal events in the electrical signal is generated if the characteristic quality differs from the rated value by more than a selected amount.

Abstract: To make it possible to suppress spurious signals of any type without having a negative effect on the stimulation or detection characteristics of a cardiac pacemaker, a signal processing unit is provided which prevents control signals from being applied to the device for controlling the heart stimulation pulses when signals from the two unipolar pacemaker electrodes are received at substantially the same time.
