    摘要: A method and apparatus, especially suited for computers that can execute fused multiply-add instructions, for performing a fast Fourier transform (FFT) are disclosed. Divisions by zero that create a risk of error in other methods are avoided. In a first example embodiment, a zero divisor is detected and the division circumvented by performing an alternate computation. In a second example embodiment, a zero divisor is detected replaced by a safe finite value. In a third example embodiment, two optimized FFT kernels are used, one avoiding division by a zero real part of a root of unity and one avoiding division by a zero imaginary part. In a fourth example embodiment, a first kernel computes some kernel iterations without multiplication, and a second, optimized kernel computes the remaining iterations without risk of division by zero.

    摘要: A method for forming a film of material using chemical vapor deposition. The method includes providing a substrate comprising a pattern of at least one metallic nanostructure, which is made of a selected material. The method includes determining a plasmon resonant frequency of the selected material of the nanostructure and exciting a portion of the selected material using an electromagnetic source having a predetermined frequency at the plasmon resonant frequency to cause an increase in thermal energy of the selected material. The method includes applying one or more chemical precursors overlying the substrate including the selected material excited at the plasmon resonant frequency and causing selective deposition of a film overlying at least the portion of the selected material.

    摘要: A portable device that produces inconspicuous sounds for event notification is disclosed. One type of inconspicuous sound is a sound that the human body makes in response to an involuntary bodily function. For example, the portable device could produce the sound of a cough to alert the user of an event. Other types of inconspicuous sounds are sounds that are commonly heard in the environment. For example, when in a restaurant the sound of clinking glasses is a common sound.

    摘要: A pipe corral connector consisting of a pair of bolts having corresponding hingedly coupled first ends, and second, threaded ends. The second end of one of the bolts is provided with a right hand thread while the second end of the other bolt is provided with a left hand thread. The threaded ends of the bolts are brought together with a nut that is internally threaded halfway with a right hand thread and halfway with a left hand thread. The nut provides a turnbuckle-like effect in bringing the two bolts together and tightly joining intersecting or parallel pipes of a pipe corral. The connector eliminates all sharp edges which might otherwise injure a corralled horse. The inside surface of the connector bolts may be serrated or notched to provide increased friction at the point of pipe connection. The nut and one of the bolts may be marked to identify matching thread sense to facilitate determination of the correct orientation of the nut.
