  • Publication number: 20140129111
    Abstract: The system for mitigating an overspeeding condition of a turbine engine can include a sensor for measuring an actual speed of a gas generator turbine of the turbine engine and a processor for deriving a delta, the delta being a comparison between the actual speed of the gas generator turbine and a predicted gas generator turbine speed. The system is configured for detecting the overspeeding condition when delta is higher than a predetermined threshold. A method of detecting an overspeeding condition during operation of a turbine engine can include measuring an actual speed of a gas generator turbine, then evaluating a delta between the actual speed of the gas generator turbine and a predicted speed of the gas generator turbine, then comparing the delta to a threshold value.

  • Publication number: 20130124016
    Abstract: A system for detecting degradation of a servo valve; having a controller, a servo valve, a position sensor, and a rate monitor. The controller receives inputs and transmits command data. The servo valve has an actuator and is conductively coupled to the controller to receive command data from the controller and move the actuator in response to the command data. The position sensor operably associated with the servo valve for measuring movement of the actuator and transmits corresponding movement data to the controller. The rate monitor coupled to the controller and position sensor for receiving the command data and the movement data as inputs respectively. The rate monitor processes the inputs to produce a steady state rate error signal. The rate monitor compares the steady state rate error signal to selected operational limits and produces a telemetry output when the operational limits are exceeded.

  • Patent number: 7690511
    Abstract: A child resistant blister packaging having an upper cover sheet with at least one aperture, a bottom backing card with at least one scored exit port, and a blister laminate situated between the cover sheet and the backing card, the blister laminate includes at least one blister containing a cavity for receiving a pill and a foil layer adhered to the a bottom surface of the sheet. The blister protrudes through the aperture in the cover sheet and is arranged on a carrier tab that will not line up in registry with the scored exit port in the backing card. Upon the application of sufficient force, the blister can be moved to align the pill-receiving cavity with the scored exit port and the blister can be collapsed to force a medicament stored in the cavity through the foil layer and the scored exit port.

The blister protrudes through the aperture in the cover sheet and is arranged on a carrier tab that will not line up in registry with the scored exit port in the backing card unless a force is applied to the blister to sever a connection means holding the carrier tab in place. Upon separating the connections means, the blister can be moved to align the pill-receiving cavity with the scored exit port and the blister can be collapsed to force a medicament stored in the cavity through the foil layer and the scored exit port.

  • Patent number: 6695264
    Abstract: The present invention is a power lever tactile cueing system for providing tactile alerts to pilots as operational limits of an aircraft are approached. The cueing system generates a tactile cue comprising a variable dive rate and a variable friction force on a power lever of an aircraft. The cueing system provides spring-like tactile cues when power commands reach a predetermined operating limit, without the use of mechanical springs. The cueing system trims down the power lever position and provides the additional friction force based upon aircraft and engine state. The cueing system remains activated until the aircraft is again operated within its operational limits. The pilot may override the cueing system in certain situations.
