Abstract: A gigahertz sensor array packaging solution for harsh operating environments is disclosed. The sensor array packaging system includes a structural core body comprising sensor mounting features on a surface thereof and an alignment through hole extending from the surface to a backside thereof which incorporates finned features providing cooling and stiffness. The sensor array packaging system further includes one or more electro-optical components mounted to the backside of the structural core body. The sensor array packaging system further includes a wiring board comprising a plurality of sensor array elements contacting walls of the spiral ribbon configuration, each having a cable extending through the through hole to at least one of the one or more electro-optical components.

Abstract: A system and method are provided for transferring a packet across a data link. The packet may include a stream of data symbols which is delimited by one or more framing symbols. Corruptions of the framing symbol which result in valid data symbols may be mapped to invalid symbols. If it is desired to transfer one of the valid data symbols that has been mapped to an invalid symbol, the data symbol may be replaced with an unused symbol. At the receiving end, these unused symbols are replaced with the corresponding valid data symbols. The data stream of the packet may be encoded with forward error correction information to detect and correct errors in the data stream.

Abstract: A semi-flexible vehicle headliner assembly and a method of installing the same are provided. The headliner assembly includes a headliner piece and a support unit. The headliner piece is bendable to permit variable shaping for installation. A method of installing the headliner assembly with an upper surface to the inside of a vehicle roof is provided which includes the steps of connecting a back side of a support unit to the inside of the vehicle roof and connecting the upper surface of the substrate to the roof of the vehicle temporarily until the substrate can be securely installed.

Abstract: The inventors herein disclose new heterobifunctional chromophores that are capable of coupling with two distinct moieties. One moiety may be either a signal-enhancing agent or a blocking agent. The second moiety may be one member of a specific binding pair. The invention is based in part on the surprising result that when a chromophore is used as a "cross-linker" between a signal-enhancing agent and a member of a binding pair (essentially being buried between the two), the signal of the chromophore is not quenched. This arrangement, wherein the chromophore acts simultaneously as a cross-linker and a detectable compound, provides significant advantages over previously known compounds since the chromophore is sterically hindered from interacting non-specifically with substances present in the test systems. Moreover, the chromophore can be used as a cross-linker with little or no loss of detectable signal.

Abstract: A rapid, simple method for preparing beads for calibrating flow cytometers which contain a known number of fluorophores per bead is presented. Briefly, the invention utilizes beads coated with a stable complex of a fluorophore and an enzyme. the enzymatic activity of a known number of beads gives an accurate measure of fluorophore density on those beads.
