摘要:
A method is provided for detecting a fault condition in a hydraulic brake system of a vehicle having a first hydraulic brake circuit and a second hydraulic brake circuit. A correlation ratio is determined between a measured pressure and the actual vehicle acceleration. A first wheel velocity differential is determined and a second wheel velocity differential is determined. A weighting value is selected in response to determining whether the correlation ratio is within the predetermined range and whether the first wheel velocity differential and the second wheel velocity differential are opposite signs. The selected weighting value is added to a fault counter. A determination is made whether the fault counter is equal to or greater than a predetermined threshold. A fault condition is detected in response to the fault counter greater than or equal to the first predetermined threshold.

Embodiments of a uniformly porous membrane covering an endoprosthetic device, for example, a stent used to treat an aneurysm, are described. Some embodiments have a pore size and spacing that provides a material ratio of between 70-80% in the deployed state. Material ratio is the proportion of the total porous segment of the membrane that corresponds to membrane material, the remainder being pores. In some embodiments, pore size ranges from about 10-100 μm. In some embodiments, pores are equidistantly spaced with pore spacing in a range of about 40-100 μm. The combination of pore size and spacing are effective to provide a membrane that substantially prevents flow to the aneurysm, while maintaining flow to perforator vessels. In some embodiments the membrane includes permanently attached agents that promote attachment of endothelial cells or progenitors and healing of the aneurysm, or reduce immune responses detrimental to the healing process.

An automated balloonsonde launcher and a method for an automated balloonsonde launch are disclosed. The automated balloonsonde launcher, for example, may comprise a collapsible protective cover forming an inner region for receiving a balloon, a gas inlet for receiving a gas, a gas outlet for mating with a balloon, a valve operable between the gas inlet and the gas outlet for inflating a balloon within the inner region of the protective cover. The launcher further comprises a controller that controls the valve to inflate a balloon within the protective cover, opens an opening in the protective cover and releases a balloon through the opening of the protective cover.
摘要:
To reduce the number of processors and/or displays in mobile equipment, an operating system is emulated in one example. A primary operating system runs on a processor or uses a particular display. The emulated operating system shares the same processor and/or same display. The emulation allows use of applications drafted or written for different operating systems in a common or shared environment. As another example, a virtual terminal function is emulated on a particular device. The particular device interacts with additional sources of information for displaying images on a same display. Using emulated operating systems or virtual terminals, a navigation program is used in a vehicle. An additional program is run on the same processor or shares the same display in the same vehicle at substantially the same time.
