摘要:
A brake rotor has double annular vents with cooling vanes connecting inboard and outboard cheeks of a rotor to a central support ring. Each of the annular vents provides separate passages for cooling the adjacent cheek of the brake rotor and separate inlets are provided for the dual vents from opposite sides of the central support ring. Aligned and staggered vane embodiments and parallel and angled passage embodiments are disclosed. The dual vents increase both the flow rate and the surface area for heat transmission and flow the air closer to the heated cheek surfaces. The staggered vanes improve stiffness and the slanted passages have potential stiffness and heat sink advantages.

The invention provides a method for diagnosing amyotrophic lateral sclerosis (ALS) in a subject, a method for assessing the effectiveness of a drug in treating ALS, and a method for determining the site of onset of ALS in a subject. Each method comprises (a) obtaining a sample from the subject, (b) analyzing the proteins in the sample by mass spectroscopy, and (c) determining a mass spectral profile for the sample. In some embodiments, the method comprises comparing the mass spectral profile of the sample to the mass spectral profile of a positive or a negative standard.
