A process and system for quality assurance. The process includes developing a high level quality assurance resource estimate and a high level quality assurance time estimate; producing a business analysis outline; and creating an acceptance test plan using an acceptance test plan template with the business analysis outline. The process further includes creating a plurality of test cases to be carried out during a test execution phase of the quality assurance process using the acceptance test plan; refining the high level quality assurance resource estimate and the high level quality assurance time estimate based on the acceptance test plan; executing each of the test cases in an acceptance test to produce a set of test results for each of the test cases; and evaluating the test results against the refined high level quality assurance resource estimate and the refined high level quality assurance time estimate. One or more defects tracked during the execution of the test cases are reported and a sign off of the acceptance test is negotiated with a client. An application audit package is created and stored for future reference.

In one embodiment, the present invention relates to primary alcohol-terminated polyisobutylene compounds, and to a process for making such compounds. In still another embodiment, the present invention relates to polyisobutylene compounds that can be used to synthesize polyurethanes, to polyurethane compounds made via the use of such polyisobutylene compounds, and to processes for making such compounds. In yet another embodiment, the present invention relates to primary alcohol-terminated polyisobutylene compounds having two or more primary alcohol termini and to a process for making such compounds. In yet another embodiment, the present invention relates to primary terminated polyisobutylene compounds having two or more primary termini selected from amine groups or methacrylate group.
摘要:
A family of silicone rubbers (e.g., polydimethylsiloxane) carrying one or more cyanoacrylate groups and their methods of production are provided. These silicone rubbers endowed with cyanoacrylate groups are useful in a variety of wound care applications, including wound closures, adhesives, sealants and skin protectors. The silicone rubber moiety provides oxygen and moisture permeability (i.e., “breathability”), biocompatibility, optical transparency, and good mechanical properties, while the cyanoacrylate group imparts instantaneous adhesion/attachment to living tissues such as skin on par with that of contemporary cyanoacrylate-based wound care products.

In one or more embodiments, the present invention relates to a substantially homogeneous miscible liquid adhesive composition comprising a relatively high number average molecular weight (Mn=6,000-10,000 g/mole) cyanoacrylate tri-telechelic star polymer having polyisobutylene chains terminated with cyanoacrylate groups (High-Ø(PIB-CA)3); 2-octyl cyanoacrylate (Oct-CA); and a relatively low molecular weight (Mn=1,000-4,000 g/mole) cyanoacrylate tri-telechelic star polymer having polyisobutylene chains terminated with cyanoacrylate groups (Low-Ø(PIB-CA)3). The Low-Ø(PIB-CA)3 compatibilizes the High-Ø(PIB-CA)3 and Oct-CA removing the need for a solvent. When the substantially homogeneous miscible liquid adhesive compositions of various embodiments are reacted with a nucleophile, such as water or an initiator, they form a polymer co-network suitable for any of a number of biomedical applications, from wound closure and healing of skin tissue, to sealant for surgical cuts.

摘要:
A method and system for collecting test and measurement data for a wireless communication system utilizes a network overlay geo-location system to collect the data. The wireless communication system has plural base stations defining a signal coverage area for communication with a mobile appliance and collects test and measurement data simultaneous on the forward and reverse links during standard geo-location processes. The wireless communication system also collects test and measurement data when the network overlay geolocation system is in an idle state.
