Abstract: A carrying device adapted to hold one or more RF tokens and incorporates electrically conductive linings to shield said tokens from each other when the device is open or an unshielded compartment containing an individual token is presented to a reader but which shields the tokens from all electromagnetic radiation when the device is closed. The linings are made from a metal foil or other conductive material and a typical device has the general construction of a caring case or wallet which has compartments to hold sundries, bank notes, cards and visual material and in particular to hold RFID tags and contact-less cards. The wallet or case may also contain one or more panels adapted to hold RFID tags and contact-less cards and to fold out of the wallet when the latter is open allowing individual RF tokens to be presented to a reader.

Abstract: Disclosed is a method, system, and program for error checking raster objects including pixel information for a print job. A plurality of raster objects form the print job. A raster object is received including sequence information indicating an ordering of the raster object with respect to other raster objects in the print job. A determination is made from the sequence information as to whether the raster object is received in a correct order with respect to other raster objects in the print job. This ensures that the pixel information for the raster object is intended for a current pixel line being processed. An indication of error status is made if the sequence information indicates that the raster object was not received in the correct order with respect to the other raster objects in the print job.

Abstract: Biosyntheses of compounds whereof at least portions are polyketides produced by means of polyketide synthase (PKS) enzyme complexes are carried out after specific alterations have been made within the acyltransferase (AT) domains of the PKSs. Particular motifs in or near the substrate binding pocket are disclosed, such that alterations therein affect substrate specificity.

Abstract: There is disclosed a multi-purpose computer duster that is capable of cleaning a monitor, keyboard and the like. In addition there is an optional staple remover integrated into the blade section of the duster.

Abstract: A method and system in a computer network for dynamically bundling and launching hypertext files within archive files, wherein the computer network includes at least one client connectable to one or more servers. Initially, an archive file is established within the computer network wherein particular subroutines are maintained. Thereafter, a particular hypertext file is associated with a selected subroutine maintained within the archive file. The particular hypertext file and the selected subroutine are subsequently bundled together within the archive file. Thereafter, the archive file is automatically transmitted to the client from a server maintained within the computer network, in response to a client request to download the hypertext file, such that the subroutine and the hypertext file are downloaded within a single selected archive file from the server, thereby reducing download time and increasing data packaging efficiency.

Abstract: A device controls in real time the assembly of data for a bit map scanning device, such as a laser printer, under supervisory control of a host processor. The image data words are stored in a source memory and assembled in a video buffer, and automatically scanned out to the scanning device. The host processor generates a simplified set of control words that defines graphics, text and layout of the page to be assembled. A raster interface synchronizes the output of the assembled data with the scanning device. Three basic modes are supported: (1) dispatch mode, (2) font read/write mode, and (3) graphics load mode. The dispatch mode is the normal operational mode which provides for dispatching data from a source memory location to the video memory and for supplying data from the video memory out to the raster printer. The font read/write mode gives the host the ability to read/write font or graphics data from/to the source memory or the video memory.

Abstract: A key telephone system signal priority arrangement is disclosed wherein each type of call in a key telephone system is assigned a distinctive priority. When a call is directed to a station engaged in an existing lower priority call, a warning tone is given to both parties engaged in this existing call. The existing call is then automatically placed on hold while the preempting call is completed to the called station such that the called station can answer the preempting call "hands-free".

Abstract: A key telephone system is disclosed in which a direct station selection (DSS) arrangement reduces the number of operations required for the attendant to extend an incoming central office call to a station. The operation of one or more DSS keys on any of the attendant consoles in the key telephone system automatically places the calling central office line on hold and establishes a communication path through the DSS key contacts from the attendant to the selected station. DC bias on this communication path activates a loudspeaker and microphone arrangement in the selected station so the called party may converse with the attendant "hands-free." Additionally, the DSS arrangement provides the capability of utilizing any station in the key telephone system as the attendant position.

Abstract: A key telephone system is disclosed in which intercom calls may be answered "hands-free" at the called station. Intercom calls are originated in the standard manner, with the subscriber picking up the handset at the calling station and dialing the number of the called station. A voice communication path is established through the station selector to the telephone set represented by the dialed number. DC bias on this communication path through the station selector activates a loudspeaker and microphone arrangement in the called telephone set. The called party may thus converse "hands-free" with the calling party by utilizing the activated loudspeaker and microphone of the station set, and need not manipulate the station set for the duration of the conversation.

Abstract: Magnetic disk recording apparatus including a pair of magnetic transducers contacting the opposite sides of a magnetic disk and each carried by a swingable arm. The arms are interconnected together so that the swinging movement of one of the arms is transmitted to the other arm to cause an opposite swinging movement of the other arm for simultaneously moving the transducers away from the magnetic disk. An electromagnet actuates one of the arms so as to thereby also move the other arm.
