An exterior surface extends from the first end to the second end of the nozzle. A plurality of vanes are disposed on the exterior surface and extend from the first end to the second end of the nozzle. A plurality of channels form along the exterior surface of the nozzle.

Abstract: A method at a client device includes displaying media library information corresponding to a set of media items. The media items include one or more local media items, the one or more local media items including media items stored at the client device, and one or more remote media items, the one or more remote media items including media items stored at a remote system and not at the client device. The method also includes displaying, concurrently with displaying the media library information, affordances identifying the remote media items; detecting user interaction with an affordance identifying a respective remote media item; and in response to detecting the user interaction, initiating a process for downloading a copy of the respective remote media item to the client device for storage at the client device.

Abstract: A Sodar apparatus is disclosed for sounding the atmosphere. The apparatus includes a transducer for converting an electrical signal to an acoustic wave and/or vice-versa and transferring means associated with the transducer for transferring the acoustic wave towards the atmosphere and/or for transferring a reflected acoustic wave from the atmosphere. The apparatus further includes isolating means or structure for isolating or attenuating the acoustic wave such that energy of the acoustic wave transferred in a substantially horizontal direction is reduced below energy of the acoustic wave transferred in a substantially vertical direction by a factor of at least 45 dB and more preferably by a factor of at least 70 dB. A method for sounding the atmosphere is also disclosed.

Abstract: The frequency of a clock signal is compared to a predetermined range. If the measured frequency is outside the range, a system controller determines if a current operating state of the overall system allows for the internal clock to be adjusted back into compliance. If the controller determines that the current system state allows for the change, then a control signal to the internal clock signal source is changed by the smallest increment available, either to increase or decrease the frequency. If the internal clock signal is out of the desired range, and the system controller does not decide to modify the frequency, the controller may increase the size of the range by decreasing the lower bound and/or increasing the upper bound.

Abstract: System and method for implementing a secure processor data bus are described. One embodiment is a circuit comprising a processor disposed in a processor partition, the circuit further comprising a first set of peripherals disposed in a first peripheral partition; a second set of peripherals disposed in a second peripheral partition physically isolated from the first peripheral partition; a first state control register for controlling access to the first set of peripherals by the processor; and a second state control register for controlling access to the second set of peripherals by the processor. When the first and second state control registers are in a first mode of operation, the processor has read and write access to the first set of peripherals and write only access to the second set of peripherals.

Abstract: A method and apparatus for visually characterizing modulated carrier signals, particularly digitally modulated microwave signals, which may be subjected to multipath fading distortion. The method involves sampling the amplitude dispersion of the received signal during a test period, counting the number of times the sampled values fall within each of a number of value ranges and displaying the count per range against range so that counts corresponding to positive and negative amplitude dispersion values are shown in a symmetrical fashion. The shape of the resultant display provides a useful characterization of the signal.

Abstract: A method of characterizing a modulated carrier signal by generating electrical signals which represent arithmetic ratios and which can be used to construct a histogram indicative of the quality of the modulated carrier signal. For a digitally modulated carrier signal, time spaced samples of in band amplitude dispersion of the signal are generated and first counts are made of the number of occurrences of particular values of in band dispersion, over a range of such values. The error ratio of the decoded modulated carrier signal is also monitored and seconds counts are accummulated, of the numbers of occurrences of respective values of in band amplitude dispersions which at least substantially coincide with the value of said error ratio crossing a predetermined level.
