The rear end of the air intake internal wall and the front end of the fan casing are uniform, and have no projections that join the internal wall and casing together.

Abstract: Disclosed herein are detectors of audio ringing feedback, that is decaying feedback with a gain of less than one, those detectors utilizing a repeated gain measurement that applied to a range of gain values characteristic of ringing-type feedback. Those gain measurements, while in the range, increase a probability measurement of feedback. When the probability of feedback reaches a threshold, a detection of feedback is made and feedback countermeasures, such as the application of a notch filter, may be applied. Optionally, the audio gain around likely frequencies of feedback may be enhanced for a time to increase the resolution of identification of a feedback frequency, which may be identified through an interpolative method. Repeated gain measurements may also identify building-type feedback. A ringing detector may include more than one range of detection, for example for building, strong-ringing and weak-ringing feedback.

Abstract: An air frame fastener wrench includes first and second handles pivotally attached to one another. A ratchet head of the first handle includes a selectively rotatable driver mateable with a socket. As the first and second handles are brought towards one another, the driver rotates the mated socket and an engaged collar of an air frame fastener. A key, which is connected to the first or second handle for preventing rotation of the key, extends through the ratchet head and prevents rotation of a pin of the air frame fastener as the collar is tightened thereto.

Abstract: A method is presented to improve the accuracy of time synchronization of data. The invention consists of a timing module compromising a GPS interface with ability controller-based timing standard, high speed inputs and outputs and an asynchronous interface to an external processor system. It attaches a time-stamp referenced to an absolute time standard to transitions on the high speed inputs and a means for delivering these time stamps referenced to the high speed input to a computer or network. Alternatively the computer or network can specify a high speed output and an absolute time for an output transition and the timing module can deliver the specified output transition at the specified absolute time. Compared to existing systems of time synchronization, it will improve the accuracy of the timed data from the current Ethernet tolerance of up to 5 milliseconds to a possible tolerance of 250 nanoseconds.
