Title: Osmotic delivery system with membrane plug retention mechanism
Inventor: AYER RUPAL
IPC: A61K9/52
Filed: 1998-12-28
Granted: 2001-07-21
Abstract: An osmotic delivery system has a membrane plug retention mechanism which can also be used to control the delivery rate of a beneficial agent from the osmotic delivery system. The osmotic delivery device includes an implant capsule containing a beneficial agent and an osmotic agent. Holes are formed along a side wall of the implant capsule at an open end of the capsule. When the membrane plug is inserted into the open end of the capsule the membrane material swells into the holes in the capsule side wall creating a large frictional force which prevents expulsion of the membrane plug. A beneficial agent delivery rate of the osmotic delivery system is controllable by varying the size and number of the holes to change the amount of exposed surface area of the membrane plug. An increase in the surface area of the membrane plug exposed to the exterior environment causes a corresponding increase in the liquid permeation rate of the membrane and thus, increases the beneficial agent delivery rate.

Title: Method and apparatus for identification of objects by a reader
Inventor: MARSH MICHAEL JOHN CAMILLE
IPC: G06K7/00
Filed: 1999-03-04
Granted: 2001-04-01
Abstract: An identification system is provided for identifying a plurality of object-based transponders using an interrogator. The interrogator includes a transmitter for transmitting an interrogation signal to the transponders, a receiver for receiving identification signals from the transponders, and processor means for determining the individual and correct receipt of an identification signal. The transponders operate on the basis of backscatter modulation, and include a detector for detecting the presence of an interrupt signal from the interrogator. Control logic responsive to the detector is arranged to cease signal transmission from the transponder if the transponder completes transmission of the identification signal without receiving an interrupt signal during such transmission. The interrogator is arranged to receive the identification signals from the transponders and substantially contemporaneously to determine if any identification signal has been individually and correctly received. In the event of any identification signal not being individually and correctly received, the interrogator, at substantially the same time, transmits a common interrupt signal for temporarily suspending signal transmission from the transponder if the transponder is transmitting its identification signal at the time it receives the interrupt signal. The transponder independently ceases signal transmission if it completes transmission of an identification signal without receiving an interrupt signal.

Title: A two-step chemical-mechanical polishing method
Inventor: YI GUAN-JIUN
IPC: B24B1/00
Filed: 1999-05-17
Granted: 2000-06-21
Abstract: This is a two-step chemical-mechanical polishing. First, fumed abrasive is used to remove most material, such as the dielectric layer above the barrier layer or the metal layer above the barrier layer, from the work-piece. The fumed abrasive contains larger grains with quick grinding speed and can, therefore, it can remove most work-piece material in a short period of time. The grinding will also improve surface flatness of the semi-conductor structure. And then, the second step polishing with colloidal abrasive is used to remove the work-piece residual material for uncovering the dielectric layer or the barrier layer. The colloidal abrasive contains smaller and even grains, which are of less damaging to the surface of semiconductor structure and also will improve evenness of the surface structure.
