Patent CA-2744459-C (CA)
Inventor: BROWN CHARLES PHILLIP
IPC: H04S3/02

Granted: 2016-06-14
Abstract: Method and system for generating output signals for reproduction by two physical speakers in response to input audio signals indicative of sound from multiple source locations including at least two rear locations. Typically, the input signals are indicative of sound from three front locations and two rear locations (left and right surround sources). A virtualizer generates left and right surround outputs useful for driving front loudspeakers to emit sound that a listener perceives as emitting from rear sources. Typically, the virtualizer generates left and right surround outputs by transforming rear source inputs in accordance with a head- related transfer function. To ensure that virtual channels are well heard in the presence of other channels, the virtualizer performs dynamic range compression on rear source inputs. The dynamic range compression is preferably accomplished by amplifying rear source inputs or partially processed versions thereof in a nonlinear way relative to front source inputs.

Abstract: The present invention relates to an attachment arrangement that comprises a body, an attachment component and a fastener. One of the body (20) and the attachment component defines a protrusion (22) and the other of the body (20) and the attachment component defines a recess configured to receive the protrusion (22). The fastener is operative to resist separation of the body (20) and the attachment component when the protrusion (22) is received in the recess. Each of the protrusion (22) and the recess defines a surface profile (28, 30) with the surface profiles cooperating with each other to force the body (20) and the attachment component progressively apart from each other against the operation of the fastener as the body (20) and the attachment component are rotated in relation to each other when the protrusion (22) is received in the recess. The body (20) and the attachment component are rotated about an axis that extends in substantially a same direction as a direction in which the body (20) and the attachment component move together and apart when the protrusion (22) is being received in and removed from the recess.

Title: Casting composite ingot with metal temperature compensation
Inventor: WAGSTAFF ROBERT BRUCE
IPC: B22D7/02
Filed: 2011-02-09
Granted: 2014-04-01
Abstract: An exemplary embodiment of the invention provides a method of direct chill casting a composite metal ingot. The method involves sequentially casting two or more metal layers to form a composite ingot by supplying streams of molten metal to two or more casting chambers within a casting mold of a direct chill casting apparatus. Inlet temperatures of one or more of the streams of molten metal are monitored at a position adjacent to an inlet of a casting chamber fed with the stream, and the inlet temperatures are compared with a predetermined set temperature for the stream to determine if there is any difference. A casting variable that affects molten metal temperatures entering or within the casting chambers (e.g. casting speed) is then adjusted by an amount based on the difference of the compared temperatures to eliminate adverse casting effects caused by the difference of the inlet temperature and the set temperature. Preferably an adjustment is selected that causes the monitored temperature to approach the set temperature. Another exemplary embodiment provides equipment for operation of the method.

Abstract: A system includes a processor. The processor is configured to receive network traffic that includes a data block. The processor will generate a unique identifier (UID) for the file that includes a hash value corresponding to the file. The processor will determine whether the file is indicated as good or bad with the previously-stored UID. The processor will call a file -type specific detection nugget corresponding to the file's file -type to perform a full file inspection to detect whether the file is good or bad and store a result of the inspection together with the UID of the file, when the file is determined to be not listed in the previously-stored UIDs. The processor will not call the file-type specific detection nugget when the file's indicator is "good" or "bad" in the previously-stored UIDs. The processor will issue an alert about the bad file when the file's indicator is "bad".

Abstract: A rotational driveshaft coupler that converts a rotating shaft motion into two orthogonal oscillations and at the opposite side of this coupler, a third oscillator converts the oscillations back to a rotational motion. At least one slip free seal can be constructed from the coupler to its housing to separate the space occupied by the output shaft from the space occupied by the input shaft. Each of the three oscillating motions can be guided by bearings, gears and tracks to reduce frictions and heat generation. Permanent magnet pairs are used to prevent bifurcation and force the output shaft to follow the rotation direction of the input shaft. Unlike in magnetic coupling, the torque transmission here is direct.

Abstract: Provided are a magnesium-based alloy and a manufacturing method thereof. In the method, a magnesium alloy is melted into liquid phase, and an alkaline earth metal oxide is added into a molten magnesium alloy. The alkaline earth metal oxide is exhausted through surface reduction reaction between the melt and the alkaline earth metal oxide. Alkaline earth metal produced by the exhaustion reacts with Mg and/or other alloying elements in the magnesium alloy so that an intermetallic compound is formed. The magnesium prepared by the method is excellent in fluidity and hot-tearing resistance. To this end, the alkaline earth metal oxide added is CaO, and the added amount of CaO is 1.4 to 1.7 times the target weight of Ca to be contained in the final Mg alloy.
