Abstract: Disclosed are apparatus and techniques for escalating an instant messaging (IM) session between two or more users to an audio session so that a communication device (by one or more users) that will optimize the audio session is selectively and intelligently utilized. In one embodiment, if an IP (Internet Protocol) phone is connected to the computer on which an IM session is being escalated, the IP telephone may be used instead of the computer device's own soft telephone so as to maximize audio clarity and quality. In another embodiment, a user's cell phone may be utilized for a mobile user who is using a laptop that is not coupled to an IP telephone or who is communicating from a hotel room in which a telephone call is typically more expensive than a cell phone call. Numerous embodiments for optimizing such audio sessions are described herein.

Abstract: The present invention includes methods and devices for providing safeguards to the access of certain substances. Some implementations provide alerts and/or other appropriate actions when substances are subject to spoilage or expiration. Some implementations provide responses to potentially dangerous combinations of substances. Other aspects of the invention involve determining the allergies of a user and providing a warning when allergens are, or recently have been, present. One preferred embodiment provides a smart medicine cabinet for helping to provide medication safely to a patient and to provide other related services.

Abstract: Systems and methods for performing rapid genomic DNA analysis of samples, such as control samples and experimental samples. In one aspect, the system makes use of genomic DNA input, rather than gene expression input such as mRNA and/or cDNA associated with mRNA. The systems and methods perform statistical analyses on data generated from the samples to determine which DNA sequences in an identified set of DNA sequences have a basis of variation in an experimental sample when compared to a control sample, and additionally provide a quantitative measure of this variation. The quantitative measure may be based on metrics such as copy number and/or fold-change. The systems and methods employ this statistical framework in DNA-based evaluation settings, including the evaluation/diagnosis of a pathological condition such as cancer or transgenic analysis of transgenic plants and animals.

Abstract: Substantially random ethylene and/or ?-olefin copolymers containing units derived from vicinally disubstituted olefin monomers are described. The vicinally disubstituted olefin monomers may be represented by the generic formula (R1)CH?CH(R2), where R1 and R2 independently comprise hydrocarbyl or silyl-hydrocarbyl groups containing 1 or more carbon atoms, or may be linear, branched or cyclic substituted or unsubstituted hydrocarbyl groups having from 1-100 carbon atoms, or they may contain 30 or less carbon atoms. The copolymers may be prepared by coordination polymerization by means of contacting at least one vicinally disubstituted olefin monomer and ethylene and/or ?-olefin, optionally with one or more other coordination polymerizable monomers, with a catalyst system comprising a monocyclopentadienyl heteroatom-containing Group 4 transition metal catalyst component.
