Abstract: A system for power management of air data probes is provided. The system comprises a power source in an aircraft, and two or more air data probes electrically connected to the power source. Each of the air data probes comprises a body structure coupled to a fuselage of the aircraft, and at least one electrical heater coupled to the body structure and in electrical communication with the power source. A switching mechanism is coupled between the power source and the electrical heater of each of the air data probes. The switching mechanism is controllable such that the electrical heater of each of the air data probes is electrically connectable to the power source in parallel or in series.

Abstract: An air data probe includes a probe body. The air data probe also includes a housing surrounding the probe body, wherein a cavity is defined between the probe body and the housing. The air data probe also includes a heater element disposed within the cavity between the probe body and the housing. The air data probe also includes a low melting point metal disposed within the cavity between the probe body and the housing, wherein engaging the heater element causes at least a portion of the low melting point metal to transition from a solid state to a liquid state.

Abstract: A device for cutting flat substances, such as paper, photographs and cardboard, adapted to provide a variety of decorative edged cuts. The cutting edges of the invention are arranged horizontally to enhance not only the quality and continuity of the decorative cuts, but also a user's ability to safely operate the invention. Cutting edges are optionally replaceable and can be stored in specially adapted holders located on the underside of the base plate cutting surface.

Abstract: A bias modulation amplitude monitoring system for a rotation sensor having a pair of output signal component detectors to provide magnitudes of the corresponding frequency components in that signal which are used by a component relationship determination arrangement capable of adjusting the output signal to have a selected value in a range of values for a selected rate of rotation thereof, and to correct variations therein, and having a reset arrangement capable of resetting the system if the output signal indicates an unwanted phase modulation amplitude.
