20120139341 | ENHANCED LOAD MANAGEMENT AND DISTRIBUTION SYSTEM - A system for managing distribution of electrical power includes a power management circuit, power control units, a first keyline and a second keyline. The power management circuit includes a device configured to measure power consumed by an electrical load, and a comparator comparing the measured power with a power limit. Each power control unit includes an outlet for delivering power to a load; a timing control circuit coupled to each outlet and configured to deliver an enabling signal to each outlet individually with a time delay; a signal input; and a signal output. The first keyline connects the power management circuit with the signal input of one power control unit; the second keyline connects the signal output of that power control unit with the signal input of another power control unit. Each power control unit is configured to propagate a signal to another power control signal via the second keyline. | 06-07-2012 |

20140167682 | USB Power Supply - A power supply system effective to provide power to a plurality of different personal electronic devices includes a source of AC or DC power, a power converter effective to convert the AC or DC power to a useable voltage and amperage, a remote power outlet or a plurality of remote power outlets each configured to receive one or more connectors and a signal decoder. The signal decoder determines the requirements of a connected one of the personal entertainment devices and personal computing devices and apply the requirements to the power outlet for powering the device. | 06-19-2014 |
20150239573 | APPARATUS AND METHOD TO MONITOR THE OCCUPANCY OF SEATING - Disclosed is a system and method for monitoring the occupancy of seating. Sensors provide measurements to a control circuit that determines an occupancy state for each seat. Information regarding the occupancy of the seats can be presented on a display. In some instances, additional inputs can be used to adjust the occupancy determinations to account for environmental factors. Also, the occupancy states of the seats can be cross-checked with a passenger manifest to facilitate the boarding of a vehicle containing the seating. | 08-27-2015 |
20150241209 | APPARATUS AND METHOD TO MONITOR THE OCCUPIED VOLUME WITHIN A FIXED OR VARIABLE VOLUME - Disclosed is a system and method for monitoring a storage container. Sensors and a control circuit are used to determine the amount of occupied space in the interior of a container or set of containers. Information regarding the occupied space within the container can be presented on a display, which may optionally be local to the container or at a centralized location. The determination may accommodate varying volume of the container depending on whether it is open or closed. Further inputs may adjust for variations in sensor operation depending on environmental factors such as temperature and altitude. | 08-27-2015 |
20150325998 | High-Voltage Direct Current Power Distribution and Fault Protection - A power distribution system including a high-voltage direct current unit (HVDCU) configured to receive an amount of high-frequency alternating current (AC) input power from a power source and convert the input power into high-voltage DC power, a negative voltage distribution rail and a positive voltage distribution rail that are together configured to supply the high-voltage DC power to at least one control unit (CU) electrically disposed between the negative voltage distribution rail and the positive voltage distribution rail and the CU being configured to convert the high-voltage DC power into output power compatible with at least one load and supply the output power to the loads associated with it. | 11-12-2015 |
20150326134 | Power Distribution System for Low-Frequency AC Outlets - A power distribution system in which a power source is configured to supply an amount of high-frequency input power to a centralized frequency converter unit. The centralized frequency converter unit is configured to convert the high-frequency input power into low-frequency converted power. Passenger Electronic Device Controllers receive the converted power and distribute it to outlet units. Power management functions may be integrated with the distribution system. For instance, the centralized frequency converter unit can cause to be disabled unused outlet units when the power drawn by the used outlet units exceeds a predetermined threshold. | 11-12-2015 |
20160054394 | High Reliability Power Supply Configuration and Testing - Disclosed is a power supply system having a minimum of two power supplies that are together configured to supply at least a specified level of power when one of the power supplies is in an offline condition. When in operation, a self-test control circuit causes one of the power supplies to enter an offline condition and a power interruption protection circuit of the offline power supply is tested. While the offline power supply is being tested, the remaining power supplies provide sufficient power to whatever loads may be present. | 02-25-2016 |
20160065048 | Split Rail PFC and AC Inverter Architecture - A power conversion system including power factor correction circuitry and power inversion circuitry. The power factor correction circuitry has a split-rail configuration and includes a bidirectional switch used to produce intermediate direct current power. The power inversion circuitry selectively operates switches to produce sinusoidal alternating current output power. The output power and the intermediate power are regulated together. | 03-03-2016 |
20160072293 | Multi-Mode Power Converter Power Supply System - A multi-mode power supply includes both a DC-AC/DC-DC dual-mode converter and a DC-DC converter. In a first mode of operation, the DC-AC/DC-DC dual-mode converter supplies AC power to AC loads and the DC-DC converter supplies power to a mix of steady-state DC loads and transient DC loads. If the transient DC loads request power above that which is available from the DC-DC converter, then a second mode of operation is entered. In the second mode of operation, the DC-AC/DC-DC dual-mode converter ceases to provide AC power to the AC loads and instead is cross coupled with the DC-DC converter, together supplying sufficient DC power to the transient loads that requested power. | 03-10-2016 |
