Abstract: In an aircraft seat power system, a Smart Power Distribution Connector (PDC) connects a power supply to multiple power outlets. Power to each outlet is monitored and controlled directly by the PDC that is in turn monitored and controlled by the power source. The power source and the PDC share a communication bus through which instructions and responses are communicated. The PDC has the ability to communicate with the outlets by sending instructions and monitoring and acting on the responses from the outlets. The system allows for power management from a supply of limited power. The PDC can provide current limiting, allowing the use of lighter weight and smaller wire and other components.

Abstract: Disclosed is a system for aiding in determining when a power-providing outlet is ending its usable service life and is due for service or replacement. A connection detection unit and counting unit respectively monitor connection of a device to a port and maintain a connection count of connection events. For USB type C connections a cable or device resistance detection circuit can be used to determine if a USB type C device or cable has been connected. USB Type A and AC connections can be detected by mechanical or electrical mechanisms. When a connection has been detected a counter can be incremented or decremented to record a connection. A limit value can be set and compared to the connection count and a sensory or electronic indication can be made when the limit value is exceeded.

Abstract: Systems and methods are provided for assigning unique addresses to multiple slave devices on a network implemented in a star configuration, having individual power and/or data buses connecting the slave devices to a master device. A switching circuit on the master side of the system is used to allow a unique address to be assigned to one slave node at a time. A control circuit determines the state of the switching circuit and directs the master device to re-address each slave node at the appropriate time, so as to assign a unique address.

Abstract: A system to regulate the temperature of a Source Port that includes a Port Controller having a first source power capabilities list stored thereon in a non-transitory digital media, the source capabilities list identifying a plurality of first power delivery capabilities that, based on their power requirements, may be negotiated by the Port Controller, a temperature sensor that measures a temperature of the power system and communicates that measured temperature to a comparator. The comparator compares the measured temperature to predefined limit temperatures and when the measured temperature crosses a predefined limit temperature threshold, the first source capabilities list being replaced with a second source capabilities list identifying a plurality of second power capabilities that, based on their power requirements, may be connected to the Source Port.

Abstract: Technologies are described for an adaptable power supply that can switch between two or more output voltages. The power supply includes discharge circuitry that utilizes the secondary windings of a transformer as a discharge path when the power supply switches from a high voltage level to a low voltage level. In some embodiments, the discharge circuitry is included within a synchronous rectifier. In other embodiments, the discharge circuitry is separate from the synchronous rectifier. In still other embodiments, the power supply does not include a synchronous rectifier. Whichever embodiment is used, an output capacitor can be discharged through the secondary windings of a transformer and the transformer can store that energy for future use.

Abstract: Interface circuits are disclosed for manually or automatically selecting among two or more communications protocols in ways that reduce the number of connector pins needed and/or use the same number of connector pins required for a single communications protocol. Such interface circuits are advantageously applicable to selecting and accommodating either RS-485 or 802bw communications protocols in aircraft electronics while enabling space and cost efficient designs.

Abstract: 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.

Abstract: 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.

Abstract: A transformer may include a first and a second continuous single piece multi-turn helical winding where at least some turns of the windings are interleaved. The turns of the windings are electrically insulated from one another and spaced sufficiently close together to permit inductive coupling therebetween. 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 first and second electrical conductors about a winding form to form the first and second continuous single piece multi-turn helical windings substantially concurrently. Alternatively, a second continuous single piece multi-turn helical winding may be advanced on a first continuous single piece multi-turn helical winding, for example by rotation with respect thereto.

Abstract: A method and apparatus for current detection for microelectronic devices using source-switched sensors. An embodiment of a current detector for a microelectronic device includes a first voltage sensor and a second voltage sensor. The first voltage sensor is to measure a first voltage of the microelectronic device during a first time period and a second voltage of the microelectronic device during a second time period. The second voltage sensor is to measure the second voltage during the first time period and the first voltage during the second time period. A voltage value is equal to the sum of the first voltage measured by the first sensor plus the first voltage measured by the second sensor, minus the sum of the second voltage measured by the first sensor plus the second voltage measured by the second sensor. Other embodiments are also described and claimed.
