Patent number: 11969201Abstract: A controller for an electrosurgical generator includes an RF inverter, a signal processor, a software compensator, a hardware compensator, and an RF inverter controller. The RF inverter generates an electrosurgical waveform and the signal processor outputs a measured value of at least one of a voltage, a current, or power of the electrosurgical waveform. The software compensator generates a desired value for at least one of the voltage, the current, or the power of the electrosurgical waveform, and the hardware compensator generates a phase shift based on the measured value and the desired value. The RF inverter controller generates a pulse-width modulation (PWM) signal based on the phase shift to control the RF inverter.Type: GrantFiled: August 17, 2021Date of Patent: April 30, 2024Assignee: Covidien LPInventors: Robert H. Wham, Edward L. Brannan, William D. Faulkner, Mark A. Johnston, Aaron G. Mattmiller, Donald L. Tonn

Patent number: 8479032Abstract: Power-backup capabilities are provided by implementing a variety of different methods, systems and devices. According to one such implementation, a data-storage device is implemented having a memory control circuit controlling nonvolatile and volatile memory. An operating power circuit carries primary-operating power from the host-system to the memories and control circuitry. A backup power circuit includes energy-storage circuitry with one or more energy storage devices. An isolation-regulation circuit provides voltage regulation of power from the host-system and also isolates the host-system provided power from the energy storage devices. A regulation power circuit carries the regulated power from the isolation-regulation circuit to the energy storage devices.Type: GrantFiled: June 26, 2009Date of Patent: July 2, 2013Assignee: Seagate Technology LLCInventors: Jon David Trantham, Darren Edward Johnston, Dean Clark Wilson

Patent number: 8424077Abstract: Systems and methods for unattended authentication of software applications to provide these applications with access to shared resources. A server password manager (SPM) module resident on a node also occupied by a requester software application requesting access to resources receives the requestor's request. The SPM module creates a request package containing the requestor's information as well as the node's identifying information. The request package is then transmitted to a credentials manager (CM) module in a CM node. The request package, encrypted by the SPM module with encryption keys previously generated by the CM module, is decrypted by the CM module. The contents are checked against data stored by the CM module regarding the SPM module and the requestor application when these were registered with the CM. If the data matches, then the CM provides credentials which are used to give the requestor application access to the requested resources.Type: GrantFiled: December 18, 2006Date of Patent: April 16, 2013Assignee: Irdeto Canada CorporationInventors: Garney David Adams, Robert Grapes, Yuan Xiang Gu, Richard Edward Johnston Mehan, Jack Jiequn Rong
