摘要:
A cycle with tapered drivetrain connections. The cycle includes a frame, a crank rotatably connected to the frame, and a driven wheel rotatably connected to the frame. The crank includes a crank arm and a crank spindle rotatably connected to the frame and non-rotatably connected to the crank arm. The crank spindle includes a crank mating surface to interface with the crank arm. The diameter of the crank spindle continuously decreases along at least a portion of the crank mating surface in a lateral direction. The crank arm includes a crank bore to interface with the crank mating surface. At least a portion of the crank bore has a diameter that continuously decreases in lateral direction. At least a portion of the crank bore taper has a taper rate and diameter equal to a taper rate and diameter of at least a portion of the crank spindle taper.

A process for the startup of an ATR which does not contain an ignition means is provided. Also provided is a process to ascertain ATR catalyst activity prior to introduction of sufficient oxidant to form a flammable feed mixture.
摘要:
A method of testing a surgical system that takes advantage of the fact that in a balanced irrigation/aspiration system (inflow≧outflow) the duration of the aspiration pressure recovery to the irrigation fluid source pressure immediately following pump stop is independent of pump run time. This method provides a more reliable way of detecting restricted irrigation flow configurations not detectable by the current methods, such as marginal irrigation flow cases that could potentially lead to surgical complications (e.g. chamber collapse during post-occlusion break surge).
摘要:
A portable, combination dehydrator, dry return air and condensed water generator/dispenser configured to reduce the humidity in a dry storage unit. In one embodiment, a system draws intake air from the dry storage unit across the condenser of a heat exchanger and condenses water from the air, collecting the water in a storage tank. The dried return air is ducted into the dry storage unit. In one embodiment, the source of the intake air may be selected from either the dry storage unit or an alternative source (e.g., outside air.) The selection of the intake air source may be based on the humidity of the air (e.g., if the humidity of the air in the dry storage unit is above a threshold, the dry storage unit is selected.) If both of the alternate sources of intake air have humidities below a threshold level, operation of the system may be suspended.

A method, apparatus and/or system generates a challenge for user authentication, having a challenge data element from a stored pool of challenge data elements. The challenge is based on rule data and stored usage data associated with at least some of the challenge data elements in the stored pool of challenge data elements. The generated challenge is sent for use in an authentication of a user to a sender. A method, apparatus and/or system also generates sender authentication and corresponding location information, having a data element from a stored pool of challenge data elements. Selection of the data elements is based on rule data and stored usage data associated with at least some of the data elements in the stored pool of data elements.
摘要:
A surgical system that is able to sense the onset of an occlusion or other surgical event as well as the instant an occlusion breaks. To help avoid overheating of the tip, the system determines a temperature of an eye using irrigation flow rate and reduces the power to the handpiece automatically if an overheating situation is predicted. Alternatively or in addition, the system monitors the power drawn by the handpiece, which is indicative of the cutting load on the tip, and automatically adjusts the power or stroke of the tip to compensate for increased loads on the tip.

The subject invention concerns materials and methods for gene therapy. One aspect of the invention pertains to vectors which can be used to effect genetic therapy in animals or humans having genetic disorders where expression of high levels of a protein of interest are required to treat or correct the disorder. The subject invention also pertains to methods for treating animals or humans in need of gene therapy to treat or correct a genetic disorder. The materials and methods of the invention can be used to provide therapeutically effective levels of a protein that is non-functional, or that is absent or deficient in the animal or human to be treated. In one embodiment, the materials and methods can be used to treat alpha-1-antitrypsin deficiency.
