Title: Method of drug detection
Inventor: NANJI AMIN A
IPC: G01N33/487
Filed: 1991-04-16
Abstract: ABSTRACT           Disclosed are methods of rapidly and accurately detecting a compound of interest, such as a toxic drug, in a body fluid. A liquid sample containing various native constituents and an anticipated exogenous chemical compound is obtained from the body. The sample is then subjected to analysis by ion mobility spectrometry to determine the presence of the exogenous chemical compound or related metabolite therein. The method may further include the step of separating the compound of interest from said native constituents in said fluid sample prior to analysis.

Patent CA-2069710-A1 (CA)
Inventor: BIRD RAYMOND F
IPC: H04L29/06
Filed: 1992-05-27
Abstract: A Transport Layer Protocol Boundary (TLPB) architecture is described which will permit an application program to run over   a  non-native   transport  protocol  without   first generating a protocol compensation package tailored to the transport protocols  assumed by the program's  application programming  interface  and  by  the  available  transport provider.  All transport functions required by the program are converted to standardized or TLPB representations. When a connection between the first application program and a second  remote  application  is  requested,  the  individual required   TLPB   transport   functions   are   compared   to corresponding functions supported by the transport provider. Compensations are invoked only where there is a mismatch. The node on which the remote application program runs is informed   of   the   compensations   so   that   necessary de-compensation operations can be performed before the data is delivered to the remote application program.

Title: Abrasion-resistant overcoat for coated substrates
Inventor: O'SHAUGHNESSY ROGER
IPC: G02B1/10
Filed: 1992-10-30
Abstract: The present invention provides a high transmittance, low emissivity film stack having an overcoat of an oxide of a metal chosen from the group of zinc, tin, indium, or bismuth, or an alloy including one or more of these metals, the oxide being applied in a thickness sufficiently low as to have no significant affect upon the optical properties of the coated substrate. That is, if the overcoat is lost through abrasion or chemical attack, the loss will not significantly affect the optical properties of the coating. The resulting film stack exhibits significantly enhanced durability as compared to a film stack without such an overcoat. In a preferred embodiment, a film stack of the invention includes at least one reflective metal layer, an outer, scratch-resistant metal oxide overcoat, and a metal oxide layer between the silver layer and the overcoat which is less scratch-resistant than the overcoat. 17
