Abstract: A method and apparatus for interactive communication between a first application program and a second application program over a network having delays. The first application program receives a message from the second application program. The message contains a previous state and one or more projected or future states of an object corresponding to the second application program. Each projected state includes a plurality of possible scenarios, each scenario including an associated probability value indicating a probability of the scenario. An updated state of the object corresponding to the second application program is determined based on the received message and displayed.

Abstract: A browser for requesting and receiving documents from a network includes a cache which stores a plurality of documents and has a user-defined storage limit. At least one of the plurality of documents stored in the cache is designated as a keep document. When a document is requested and received from the network, it is stored in the cache. The cache then determines whether the amount of storage used by the cache exceeds the storage limit. If the storage limit is exceeded, the cache deletes the oldest documents not designated as keep documents until the amount of storage used by the cache is within the storage limit.

Abstract: Furanone compounds and compositions having anticholinergic activity are described. The compounds have the formula: ##STR1## wherein: the dashed line indicates either the 4,5-unsaturated or the 4,5-dihydrofuranone ring;R.sub.1 and R.sub.2 may be the same or different and are hydrogen, thienyl, furanyl, or cycloalkyl (C.sub.3 -C.sub.6), benzyl, phenyl, substituted phenyl or substituted benzyl wherein the phenyl or benzyl group may be substituted with halogen, trifluoromethyl, lower alkyl, lower alkoxy or hydroxy;R.sub.3, R.sub.4 and R.sub.5 may be the same or different and are hydrogen, lower alkyl, lower alkyl substituted with a halogen, alkoxy, amino or carboxylic acid group, an alkyl or alkylene bridge between R.sub.4 and R.sub.5 or R.sub.3 and the ring N, trifluoromethyl, nitro, a cycloalkyl group containing 3 to 6 carbons, halogen, benzyl, phenyl, substituted phenyl or substituted benzyl, for which the substituents are the same as those set forth for R.sub.1 and R.sub.2 substituted benzyl or phenyl.R.sub.

Abstract: A defibrillator/pacer having separate energy storage circuits for pacing and defibrillating. The pacing energy storage is charged from residual energy from the defibrillator source to permit high energy pacing after defibrillation. In operation, energy is transferred from the defibrillation energy storage source to the pacing energy storage source which is utilized to provide energy for pacing the heart after defibrillation.
