Patent number: 10884478Abstract: An asynchronous state machine (ASM) for managing deep sleep state of a device and related methods are described. One method includes the ASM automatically detecting a request to wake up the device based on either a change in a status of a power user-interface element associated with the device or upon a detection of an attachment of an external power source to the device. The method further includes the ASM automatically initiating a wake-up sequence including turning on a battery pack associated with the device. The method further includes the ASM automatically detecting whether a power management function associated with the device is enabled and automatically transferring control of a remaining portion of the wake-up sequence to the power management function and the ASM passing the status of the power user-interface element to the power management function as needed.Type: GrantFiled: October 1, 2018Date of Patent: January 5, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Yen Ying Lee, Gene Robert Obie, Jay A. Kuehny

Patent number: 8866551Abstract: A dual compensation operational amplifier is suitable for use in an environment that experiences fluctuations in ambient energy levels. A dual compensation impedance can be determined to nullify or compensate for effects of an input offset voltage or an input bias current or both. Adjustments to the dual compensation impedance can be made based on calibration data for various environmental conditions so that the dual compensation impedance can be either pre-set for anticipated conditions in different target operational environments, or automatically adjusted in-situ. Target operational environments that may benefit from such a dual compensation impedance include remote areas that experience extreme or variable temperatures, high altitudes, space, or high radiation environments.Type: GrantFiled: September 10, 2012Date of Patent: October 21, 2014Assignee: Crane Electronics, Inc.Inventors: Cuon Lam, Jay Kuehny, David Perchlik

Publication number: 20130010399Abstract: A transformer may include a first and a second continuous single piece multi-turn helical winding, one concentrically received by the other. The turns of the windings are electrically insulated from one another and spaced sufficiently close together to permit inductive coupling therebetween. The turns may be formed of a conductor having a rectangular cross-section, which may, or may not, include an electrically insulative sheath. The single piece multi-turn helical windings may have a continuous or smooth radius of curvature, with no discontinuities or singularities between first and second end terminals. The transformer may be formed by wrapping electrical conductor about a winding form. The transformer may be used in various electrical circuits, for example converter circuits.Type: ApplicationFiled: September 7, 2012Publication date: January 10, 2013Applicant: Crane Electronics, Inc.Inventors: Christopher Dziubek, David Perchlik, Jay Kuehny

Patent number: 5521807Abstract: A secondary flyback core reset (SFCR) scheme for single-ended forward DC-to-DC converters is disclosed. The transformer secondary magnetizing inductor and a parasitic reset capacitance of the output forward rectifier diode form a secondary flyback reset circuit. The magnetic flux built up through the primary winding when the main switch is turned on is reset through this secondary flyback reset circuit when the main switch is turned off. The secondary flyback reset circuit initiates a half resonant cycle and resets the transformer. With proper design of the reset time, the maximum duty cycle of the main switch can go beyond 50%, while still using the first and third quadrants of the core B-H loop characteristics for optimum use of the core power density, and reduced RMS switching current and rectifier blocking voltages and power switch blocking voltage.Type: GrantFiled: December 16, 1993Date of Patent: May 28, 1996Assignee: Interpoint CorporationInventors: Ming L.
