Patent number: 7774064Abstract: Methods and devices for classifying a cardiac response to pacing involve establishing a retriggerable cardiac response classification window. A first cardiac response classification window is established subsequent to delivery of a pacing pulse. A cardiac signal following the pacing stimulation is sensed in the first classification window.

The cardiac signal is sensed in the second classification window if the second classification window is established. The cardiac response to the pacing stimulation is determined based on characteristics of the cardiac signal. The cardiac response may be determined to be one of a captured response, a non-captured response; a non-captured response added to an intrinsic beat, and a fusion/pseudofusion beat, for example.Type: GrantFiled: December 12, 2003Date of Patent: August 10, 2010Assignee: Cardiac Pacemakers, Inc.Inventors: Scott A.

Patent number: 7766037Abstract: A gas valve assembly includes a solenoid coil, a linearly actuated plunger, and a stop member. The plunger is disposed in the coil so that a gap exists between the plunger and the stop member at a deenergized condition of the solenoid. The assembly includes a valve having a port and a closing member. The closing member blocks the port in a closed position corresponding to the de-energized condition of the solenoid, and slidably unblocks the port in an open position corresponding to the energized condition of the solenoid. An adjustable length member is coupled to the closing member and the plunger and has a portion accessible external to the valve assembly. The externally-accessible portion of the adjustable length member is adjustable to vary the size of the gap between the plunger and the stop member when the closing member is in the closed position.Type: GrantFiled: July 25, 2007Date of Patent: August 3, 2010Assignee: Honeywell International, Inc.Inventors: Patrick R.

Patent number: 7769407Abstract: A system, apparatus, computer program product, and method for controlling output power levels of over-the-air (OTA) transmission signals from a terminal operable on a network. At least one parameter used by the terminal in establishing its proper RF output power level is provided by the network in a channel assignment message(s). The terminal can then define the proper output power level in changing circumstances, such as where the common broadcast channel is mapped on a different band than traffic channels, in connection with handover or DTM operations, etc. Further, the parameter is provided via the channel assignment message(s) in connection with DTM operation after handover, where the common broadcast channel is mapped on the same frequency band as the traffic channel. When the proper output power level has been defined using the parameter received from the channel assignment message, the terminal can communicate information to the network using the proper output power level.Type: GrantFiled: April 30, 2004Date of Patent: August 3, 2010Assignee: Nokia CorporationInventors: Antero Lundell, Tommi Kangassuo
