摘要:
This invention provides a process of sterilizing a medical device, and preferably the contents of a sealed container which comprises said medical device, comprising the step of exposing said medical device to monochromatic ultraviolet radiation whereby the Dvalue of Bacillus stearothermophilus (ATCC 7953) is at least 23.7 mJ/cm2 monochromatic ultraviolet radiation at 257 nm to the spore. Further, this invention provides a process of sterilizing a medical device comprising the step of subjecting said medical device to monochromatic ultraviolet radiation wherein the minimum total energy density of said monochromatic ultraviolet radiation at 257 nm which reaches the microorganisms present on said medical device is at least 284 mJ/cm2.This invention further provides an apparatus for delivering UV radiation to a medical device for sterilization comprising a laser and a scanner for the laser such that at least 284 mJ/cm2 at 257 nm is applied to a treatment area for said medical device. This invention provides a process and apparatus in which sterilization can be achieved in less than 20 seconds, preferably less than 15 seconds, more preferably in less than 5 seconds. The process and apparatus are efficient and continuous.

The present invention relates to soft contact lenses having an overall comfort preference of at least about 2 to 1 as compared to an Acuvue® contact lens and measured after one week of daily wear. The present invention further relates to a soft contact lens comprising an oxygen transmissibility greater than about 70 barrers/mm and physical properties suitable to provide wearer comfort over at least about 9 hours in at least about 80% of wearers, as measured in a randomized, double masked clinical study.
摘要:
A three port FIFO buffer circuit uses off the shelf static RAM and dedicated shallow, e.g. 16 word, FIFOs in a multi-level caching scheme. The circuit results in multiple, reconfigurable, deep (e.g. up to 32k word) FIFO buffers. The preferred embodiment of the invention provides a buffer that comprises a bank of 32k word RAM, six dual port 16-word FIFOs, and associated sequencing logic. The sequencing logic includes RAM address registers/counter associated with each of the six FIFOs, and manages the movement of data into and out of the RAM.
