| 20080275439 | CARDIAC ABLATION AND ELECTRICAL INTERFACE SYSTEM AND INSTRUMENT - A system for ablating tissue and electrically interfacing with a heart including an electrosurgical instrument, an energy source, and a controller. The instrument includes a shaft maintaining first and second electrodes at a distal section. The electrodes are electrically isolated from one another. The controller controls delivery of energy from the energy source, and monitors electrical signals at the electrodes. The controller is programmed to operate in a monopolar mode and a bipolar mode. In the monopolar mode, the first and second electrodes are electrically uncoupled, and energy from the energy source is delivered to the first electrode in performing an ablation procedure. In the bipolar mode, first and second electrodes are electrically coupled and serve as opposite polarity poles to apply energy to a tissue target site, detect electrical signals at a tissue target site, or both. | 11-06-2008 |

| 20110119520 | Hardware Function Generator Support in a DSP - The present invention relates to digital signal processors with an integrated module configured to compute a Coordinate Rotation Digital Computer (CORDIC) in a pipeline. The pipelined module can advantageously complete computation of one CORDIC computation for each clock pulse applied to the CORDIC module, thereby providing a CORDIC computation for each clock pulse. One embodiment advantageously computes a first portion of a computation with a lookup table and a second portion in accordance with a CORDIC algorithm. Advantageously, data in a CORDIC pipeline is automatically advanced in response to read instructions and can be automatically advanced from the beginning of the pipeline to the end of the pipeline to reinitialize the pipeline. This allows information to be retrieved from the CORDIC pipeline with relatively little overhead. The automatic starting and stopping of the CORDIC pipeline advantageously allows the retrieval of computations from efficient pipeline architectures on an as-needed basis. | 05-19-2011 |

| 20100049162 | Mediastinoscopy access, sampling, and visualization kit featuring toroidal balloons and exotracheal method of using - The present invention provides various systems, a kit, and a method for improving access to, sampling within, and visualization of areas within the mediastinal cavity for assisting a surgeon in performing a mediastinoscopy procedure. The access system includes one or more preferably toroidal balloons that can be expanded to dilate and protect the inner walls of a bodily conduit. Instruments pass through hollow spaces within the expanded toroidal balloons. The proximally positioned balloons are expanded first and the unexpanded balloons to be positioned distally are passed through them and subsequently expanded. The sampling system includes an instrument with a rounded head having two or more jaws and a slit therein at the distal end of an elongated tubular body. The visualization system includes a 360° camera that can be positioned from proximal to distal a target site and can also do a U-turn about its axis of extension. | 02-25-2010 |

| 20090270829 | PACKAGED UNDERGARMENT AND CHANGING ACCESSORIES - An undergarment and undergarment changing accessory system includes an undergarment, at least one changing accessory for cleaning or treating an undergarment wearer or caregiver, and a container comprising sheet portions that are partially sealed together with releasable seals along perimeter edge portions that may be readily pulled or peeled apart to expose the undergarment (such as a diaper) and changing accessory contained therein. A fixed or non-releasable seal or fold region may optionally connect the sheet portions after the releasable seals are opened so that the sheet portions form an enlarged sheet that can be used as a sanitary changing surface. A releasable seal established along a divider portion between the sheet portions and separating the undergarment from the changing accessory maintains the undergarment and changing accessory in isolation from one another and from the environment to prevent leaks or contamination prior to opening the releasable seals. | 10-29-2009 |

| 20090147424 | CIRCUIT BREAKERS WITH AUTOMATIC BREAKER RATING - An electronic control for a circuit breaker with automatic breaker rating is disclosed. The electronic control includes a memory to store circuit breaker ratings, a breaker rating switch to select circuit breaker ratings, and a microprocessor operatively coupled to the breaker rating switch and the memory. The microprocessor is configured to interpret a selected circuit breaker rating of the breaker rating switch, set an amplifier gain adjustment for the circuit breaker based on the selected circuit breaker rating, and transmit the selected circuit breaker rating to the memory for storage in the memory. | 06-11-2009 |
| 20090243590 | SYSTEM AND METHOD FOR MONITORING CURRENT IN A CONDUCTOR - The present disclosure describes a system for measuring current amplitude in a conductor, comprising at least one Rogowski coil, an integration circuit directly connected to the at least one Rogowski coil, a microprocessor circuit in communication with the integration circuit and configured to receive output from the integration circuit and to calculate energy data comprising current amplitude in the conductor. A method for measuring current in a conductor is also presented. | 10-01-2009 |
| 20090256426 | SYSTEM AND METHOD FOR MANAGING POWER SUPPLY TO A CIRCUIT BREAKER CONTROL UNIT - A system for controlling power in a circuit breaker trip unit is disclosed. The system includes: a user interface operably coupled to the trip unit and having a plurality of input keys; a power conditioner operably coupled to the user interface and operably coupled to a battery power source and an external power source; and a power control circuit. The power control circuit is configured to automatically electrically connect the battery power source to the power conditioner in response to activation of any of the plurality of input keys, and in the absence of an electrical connection between the external power source and the power conditioner. | 10-15-2009 |
| 20090257163 | CURRENT GAIN CONTROL OF CIRCUIT BREAKER TRIP UNIT - An electronic trip unit for a circuit breaker, the electronic trip unit includes a rating plug having a plurality of switches each configured to indicate a specified current rating for the rating plug and for selectively supplying a current rating for the electronic trip unit, a processing unit which receives and reads a value of the selected current rating from the rating plug upon power-up, and a gain control unit including a plurality of gain circuits. Each of the gain circuits including a plurality of gain switches set by the processing unit based upon the selected current rating, to control a gain of input current of the electronic trip unit. | 10-15-2009 |
| 20110063202 | Reduced Energy Let Through Mode Indication and Delay in Switching Devices - A method of improved reduced energy let through (RELT) mode selection in a switching apparatus includes receiving a request to disable a RELT mode of the switching apparatus, and, if the RELT mode of the switching apparatus is active, increasing a current threshold of the switching apparatus after a configurable amount of time has elapsed from the receipt of the request to disable the RELT mode. | 03-17-2011 |
