Title: Interconnection system for integrated circuit chips
Inventor: CHALL LOUIS E JR
IPC: G11C29/00
Filed: 1988-08-04
Granted: 1992-03-24
Abstract: ABSTRACT     A novel packaging system for VLSI circuits allows low-cost construction and maintenance of complex high density high-performance devices with low power requirements. The devices can be individually created by software means from a small selection of standardizable IC chips by disposing a plurality of chips in leadless chip carriers in a mosaic on a substrate, and configuring them by software to selectively communicate with other chips of the mosaic or even to individually change their operating function. The immediate juxtaposition of the chip carries in the mosaic eliminates transmission line data skew, and also allows considerable savings in chip space and power requirements by dispensing with interconnection drivers, receivers and bonding pads. The chip carrier mosaics may be assembled into modules suitable for plug-in connection to an interconnecting backplane to create even larger devices, and individual modules can be dynamically tested in their high-performance mode by configuring one or more modules as test modules and either plugging them into modules to be tested or making them a permanent part of the device's module array.

Granted: 1997-07-29
Abstract: Compositions  and  methods  of  manufacture  for producing a medicament composition capable of absorption through the mucosal tissues of the mouth,  pharynx,  and esophagus.     The  present  invention  relates  to  such compositions and methods which are useful in administering drugs in a dose-to-effect manner such that sufficient drug is administered to produce precisely a desired effect.  The invention also relates to a manufacturing technique that enables a therapeutic agent or drug to be incorporated into a flavored confectionary base and to compress or otherwise attach the solid confectionary mixture onto an appliance or holder. Employing the present invention the drug may be introduced into the patient's bloodstream almost as fast as through injection,  and much faster than using the oral administration route, while avoiding the negative aspects of both of these methods.  The present invention achieves these  advantages by  incorporating  the  drug  into  a compressed powder "candy" matrix.  The pH and pKa of the powder matrix can be modified to increase the absorption of the drug through the mucosal tissues.
