IPC: A61M5/31
Filed: 1996-04-25
Abstract: A pre-fillable hypodermic syringe is provided. The hypodermic syringe includes a syringe barrel having opposed proximal and distal ends and a drug-receiving chamber therebetween. The distal end of the syringe receives a needle cannula that is sealingly and protectively covered by a cap. The proximal end of the syringe is sealed by a stopper assembly. The stopper assembly includes a distal stopper that is positioned adjacent the drug pre-filled into the syringe barrel. The distal stopper is formed to exhibit acceptably low sliding forces without the presence of lubricants deleterious to the drug. The stopper assembly further includes a proximal stopper formed from a material that exhibits acceptable microbiological sealing. Because the proximal stopper is separated from the drug by the distal stopper the proximal stopper may be treated with any convenient lubricant, such as silicone oil. The distal stopper functions as a barrier between the drug and the lubricant such as silicone oil that is on or near the proximal stopper. The proximal stopper, on the other hand, provides the required microbiological sealing.

Title: Transmission of cdma signals over an analog optical link
Inventor: ARIYAVISITAKUL SIRIKIAT
IPC: H04B10/12
Filed: 1997-10-27
Abstract: A transmission system for backhauling CDMA signals from remote antennas to the centralized base station of a wireless communication system includes a laser transmitter and an optical receiver coupled to an optical fiber. Wireless signals are backhauled to the central base station without degrading signal quality, and with minimal signal processing performed at the remote antenna site. The RF drive current driving the laser transmitter is kept above a predetermined level to prevent noise caused by optical feedback into the laser transmitter caused by Rayleigh backscatter in the optical fiber. A method of testing the optical link is presented which avoids the expense of using a real CDMA system to test each link. The testing method enables the dynamic range of inexpensive, unisolated, uncooled lasers in the optical link to be increased so the optical link can cost-effectively backhaul the CDMA signals.
