Patent CA-2501878-A1 (CA)
Inventor: BETZ JOHN
IPC: H04B1/707
Filed: 2003-10-09
Abstract: Signal processing architectures for direct acquisition of spread spectrum signals using long codes. Techniques are described for achieving a high of parallelism, employing code matched filter banks and other hardware sharing.  In one embodiment, upper and lower sidebands are treated as two independent signals with identical spreading codes. Cross-correlators, in preferred embodiments, are comprised of a one or more banks of CMFs for computing parallel short-time correlations (STCs) of received signal samples and replica code sequence samples, and a means for calculating the cross-correlation values utilizing discrete-time Fourier analysis of the computed STCs. One or more intermediate quantizers may optionally be disposed between the bank of code matched filters and the cross-correlation calculation means for reducing word-sizes of the STCs prior to Fourier analysis. The techniques described may be used with BOC modulated signals or with any signals having at least two distinct sidebands.

Title: Aircraft with forward opening inlay spoilers for yaw control
Inventor: CLARK WALTER DENNIS
IPC: B64C39/10
Filed: 2003-12-16
Abstract: An aircraft (50) comprises first (68) and second (70) wings positioned on opposite sides of a longitudinal axis, a first forward opening control surface (52) attached to an upper surface of the first wing (68), and a second forward opening control surface (54) attached to an upper surface of the second wing (70) , wherein each of the first (56) and second hinges (58) is canted (01, 02) with respect to a direction perpendicular to a longitudinal axis of the aircraft. A method of providing yaw control of an aircraft is also provided.  The method comprises the steps of providing a first forward opening, canted spoiler in a top surface of a first wing of the aircraft, providing a second forward opening, canted spoiler in a top surface of a second wing of the aircraft, and operating the first and second spoilers differentially to create a yaw moment. The creation of yaw moments without any down force has application in sweptback wings where the tips are behind the center of gravity of the aircraft. The advantage is in reducing radar cross section over traditional (forward hinged, rearward opening) spoilers where there must be a spoiler on the bottom side to counter the down force created by the top spoiler.

Abstract: A housing, which may contain a hard disk drive, is configured to removably mount to a recessed surface of a console. The housing includes a lip and a biased latch arm so that the lip can be inserted into a corresponding feature in the recessed surface and the housing can be rotatably mounted to the recessed surface. The biased latch arm is retained by a latch arm retainer so that the housing is held in place. A cable connector extends from the bottom of the housing and is configured to connect to a receptor on the console when the housing is installed. When desired, a latch on the housing can be translated where the translation cause the biased latch arm to translate so as to clear the latch arm retainer. Thus the housing can be readily removed from the console. Preferably a portion of the housing extends beyond a wall of the recessed surface so that when installed, the housing alters the profile of the console.

Title: Propylene homopolymers for biaxially oriented films
Inventor: KIM SEHYUN
IPC: C08F110/06
Filed: 2004-10-13
Abstract: Propylene homopolymers useful in the manufacture of biaxially oriented films are provided. More particularly, the propylene homopolymers of the present invention are useful as core material for a multilayer biaxially oriented film. The propylene homopolymers of the present invention attain these properties by control of the average meso sequence length, Nm, in the xylene insoluble phase of the polymer concurrently with control of the quantity of xylene solubles in the polymer as a whole. The propylene homopolymers according to the current invention comprise from about 97 to about 91 percent by weight of a xylene insoluble fraction, and from about 9 to about 3 percent by weight of a xylene soluble fraction. The xylene insoluble fraction has a meso run length of less than or equal to 130. Further, the ratio, r, of the meso run length of the xylene insoluble fraction to the percent content of the xylene soluble fraction in the propylene homopolymers is 22 or less, as determined by the equation: where: Nm = average meso sequence length of the xylene insoluble fraction; and %XS = the percent content of xylene solubles in the propylene homopolymer.
