摘要:
A cable retractor for paying out and retracting an electrical cable providing electrical power to an electrical load on a movable window element comprising a first assembly having a rotatable cable spool for receiving the electrical cable for winding on the cable spool, the first assembly including a first housing having an opening therein for paying out a first end of the electrical cable wound on the spool and at least one electrical terminal for connecting a second end of the electrical cable on the spool to one of an electrical power source or the electrical load; a second assembly having at least one electrical connection connected to the first end of the electrical cable and further being connected to the other one of the electrical load or the electrical power source; thereby to provide power to the electrical load from the electrical cable; one of the first and second assemblies being mounted for movement with the movable window element and the other of the first and second assemblies being fixed; and a guide channel disposed between the first and second assemblies for guiding the electrical cable as the electrical cable is retracted into the first housing on the cable spool as the movable window element moves such that the first and second assemblies move relatively toward each other; whereby the electrical load is provided with electrical power from the electrical power source at all positions of the movable window element.
摘要:
Many current electronic systems incorporate expensive or sensitive electrical components. Because electrical energy is often generated or transmitted at high voltages, the power supplies to these electronic systems must be carefully designed. Power supply design must ensure that the electrical system being supplied with power is not exposed to excessive voltages or currents. In order to isolate power supplies from electrical equipment, many methods have been employed. These methods typically involve control systems or signal transfer methods. However, these methods are not always suitable because of their drawbacks. The present invention relates to transmitting information across an interface. More specifically, the present invention provides an apparatus for transmitting both AC and DC information across a high bandwidth magnetic interface with low distortion.

An icing detection subsystem for an aircraft turbine engine is presented. The icing detection subsystem includes a plurality of air pressure sampling ports formed within structure that surrounds a rotating component of the aircraft turbine engine. The subsystem also includes a pressure sensor arrangement coupled to the plurality of air pressure sampling ports to obtain air pressure measurements for the plurality of air pressure sampling ports. A processing module is coupled to the pressure sensor arrangement to analyze the air pressure measurements over time during operation of the aircraft turbine engine, and to generate an alert when at least one characteristic of the air pressure measurements over time is indicative of the presence of ice in the aircraft turbine engine.
