Abstract: In a local area network station (12) for a wireless LAN, a threshold level circuit (62) includes a register (134) which stores a threshold value. The station receiver (42) monitors the transmission channel and provides a receive level signal indicative of the signal level received. Transmission of a data frame by the station transmitter (46) is permitted or deferred according as the receive level signal value is below or above the threshold level, regardless of whether or not the received signal derives from a transmission by a station in the receiving station's own LAN. The threshold is dynamically updated whenever the station (12) receives a data frame from its own LAN. An improved utilization of the wireless transmission channel is achieved.

IPC: G06N5/00

Abstract: Processing techniques for enhancing execution of programs written in a logic-oriented programming language such as PROLOG are disclosed. The techniques are particularly useful for programs having class predicates and subclass predicates which are definitive of a class/sub-class hierarchy, such as the case with PROLOG's application in object-oriented programming systems, expert systems, object-oriented databases, object-oriented deductive databases, knowledge representations, etc. The techniques ensure that searching within the type hierarchy takes precedence over searching of instances of types. Important to accomplishing this function is the pre-assigning of ranks to predicates and clauses within the program to be processed. Query processing on the program is then based upon the pre-assigned predicate and clause rankings. In particular, novel rules are substituted for conventional predicate and clause selection rules of PROLOG interpreters such that predicates and clauses are preferably processed in order of ranking. In addition, certain query processing simplification steps are introduced. The net effect is a technique which eliminates redundant and unnecessary searching at the instance level by taking advantage of information available in the type lattice.

Abstract: A process for forming an adhesive-based peelable, hermetic seal for a package in which the adhesive ruptures uniformly when the package is opened. A first polyacrylonitrile packaging film has a surface thereof treated with a corona discharge. An adhesive is applied to either the treated film or an opposing second packaging film and the first and second films are brought into contact. The corona discharge treatment of the polyacrylonitrile film reduces the bond strength between the adhesive and the treated film such that the adhesive peels cleanly and uniformly away from the seal area of the treated film, without "stringing".

Abstract: The invention relates to matching of the running radius of carbon brushes to the commutator. The technical solution is based on this matching being achieved by measures which increase the wear of the carbon brushes and attempts to limit these measures exclusively to the carbon brushes and to control them exactly in terms of time and of temperature. This problem is solved according to the invention in that the commutator machine is operated during a first time period at a frequency in the region of harmonics until the maximum steady-state temperature is reached, and is operated during the subsequent time period from the frequency range of the harmonics applied in the first time period down to the range of the fundamental. <IMAGE>

Abstract: Textile discs and wheels for surface lapping/buffing are impregnated with a resin solution containing an abrasive powder suspended therein. Following vacuum impregnation and centrifugation, the impregnated buffing discs and wheels are oven-treated for polymerizing the resin. The abrasive powder incorporated in the impregnating resin provides a source of abrasive material in the work area of the disc or wheel, thus making up for the abrasive paste shortage during intervals between successive paste applications. This allows a considerable saving of abrasive paste while increasing buffing disc life.
