Abstract:
A system for providing Java-implemented Application Servers to a plurality of clients. Each of the Java-implemented Application Servers is configured to execute on a processing element of a server which has multiple independent processing elements arranged such that a failure of one processing element does not affect the operability of the other processing elements. A Distributor is provided to enable making connections with the clients and then determine which of the Application Servers actually services the clients requests. The Distributor attempts to choose the Application Server that has the fewest number of clients as the server for a new client request. A monitoring program restarts the Distributor if it fails. The system thus provides a scalable and available set of Java-implemented Application Servers without requiring any change to the Java-implemented application itself.
Abstract:
A user interface of simplifying selection of speaker volume level and power conservation level in a computer system. An icon is presented for setting the speaker volume which includes a bar graph of relative speaker volume. By depressing left or right arrow keys the graph moves and the volume level of the speaker is changed. By depressing the down arrow key when setting the volume level, the speaker is beeped to allow for a level check during the setting process. A series of icons are used to indicate and select power conservation level. Each icon includes a battery with a faucet attached to the side of the battery. Different water flow rates indicate the various conservation levels. A human figure is located adjacent the faucet to indicate the user-customerized conservation level.
Abstract:
Portable computer base housing portion has a rectangular opening therein that complementarily receives a keyboard assembly provided with latch structure to secure it in place. To install the keyboard assembly in the base housing top side opening the assembly is placed in the top side opening, the rear side tabs are inserted into corresponding openings in the top base housing side wall, the front side tabs are forwardly moved to their extended positions in which they enter facing openings in the base housing top side wall, and the cap portion are pivoted inwardly against the top side of the keyboard assembly and latched into place thereon to prevent the front side tabs from rearwardly moving to their retracted release positions.
Abstract:
A distributed computer sytem (500) includes a source endnode (502) including a source process (508) which produces message data and a send work queue (516a) having work queue elements that describe the message data for sending. A destination endnode (504) includes a destination process (510, 512) and a receive work queue (518b, 520b) having work queue elements that describe where to place incoming message data. A communication fabric (524) provides communication between the source endnode and the destination endnode. An end-to-end context (530, 534) is provided at the source endnode and the destination endnode storing state information to ensure the reception and sequencing of message data sent from the source endnode to the destination endnode permitting reliable datagram service between the source endnode and the destination endnode.
Abstract:
A method for improving SCSI controller operations by actively patching SCSI processor instructions. In a first case, tag values assigned to queues for tagged queue operation are a multiple of the SCSI processor jump instruction length. When reselected, the tag value is patched or overwritten as the least significant byte of the address of a jump instruction. The upper bytes point to the beginning of a jump table. Each entry in the jump table is a jump instruction to the sequence for a particular queue or thread. Thus simple entry is made to the desired thread without a conditional branch tree. In a second case, special SCSI operations are directly handled by the host device driver and the SCSI processor only performs conventional data transfers and similar operations. The device driver patches the message length of the SCSI processor code to an illegal value, so that an illegal instruction develops, prompting the host device driver to perform the operation at a register level. This approach allows removal of all special operation conditional branching from the SCSI processor, greatly speeding up operations.
Abstract:
A dual bin envelope tray (30) is adapted to support, in a side-by-side relationship, two stacks (32, 34) of envelopes which may be of different sizes. The envelope tray is configured to be interchangeable with the conventional paper supply tray of a printing device, such as a printer, copier or the like, and may be inserted directly into the printing device housing opening from which the paper tray is removed. Cooperating driving and driven structures, respectively disposed within the housing and on the envelope tray, function to sequentially feed the envelopes in either stack thereof into the printing device housing for passage through its existing printing and paper exit paths.
Abstract:
A language translator is provided which determines memory structure at compile time for a plurality of object classes including at least one virtual base class and at least one class derived therefrom. At compile time, space for pointers (b-pointers) is set aside in each class object that will have a base table (b-table) associated therewith. The b-pointers point, at run time, to an associated b-table containing memory offsets between the base classes of the derived class. At run time, constructors construct the class objects, starting from the most derived class object and proceeding through to the base class object. However, instead of generating the virtual tables and associated pointers, as well as the adjusting functions, at compile time, the language translator generates the code for these operation to be executed at run time. Then at run time, a virtual function table is generated for the base class. Since the necessary offsets are known at run time, all of the adjusting functions, the virtual function tables, and the virtual pointers may be generated. Thus, the system completes the construction of an object.
Abstract:
A portable computer docking base has incorporated therein a thermoelectric cooling system used to provide auxiliary operating heat dissipation for a portable notebook computer operatively docked to the base. The cooling system includes a thermoelectric (Peltier effect) heat pump unit disposed within the docking base housing and having opposite hot and cold sides. A finned heat sink member is secured to the hot side of the assembly and positioned in the path of fan-generated cooling air, and a heat slug member is secured to the cold side of the assembly and projects outwardly through an exterior wall of the docking base housing into its computer receiving area. When the computer is placed in the receiving area and docked, the cooling system heat slug member is brought into heat conductive contact with a similar heat slug member carried within the computer and thermally coupled to its microprocessor. Operating heat from the microprocessor is transferred through the contacting heat slugs, passes through the thermoelectric heat pump assembly to its hot side heat sink, and is dissipated from the heat sink to the cooling air flow within the docking base.
Abstract:
A computerized apparatus for reducing the size of a dictionary used in a text-to-speech synthesis system are provided. In an initial phase, the method and apparatus determine if entries in the dictionary, each containing a grapheme string and a corresponding phoneme string, can be fully matched by using at least one rule set used to synthesize words to phonemic data. If the entry can be fully matched using rule processing alone, the entry is indicated to be deleted from the dictionary. In a second phase, the method and apparatus determine if the entry, considered as a root word entry, is required in the dictionary in order to support phoneme synthesis of other entries containing the root word entry, and if so, the root word entry is indicated to be saved in the dictionary. If the other entries containing the root word entry can have correct phonemic data generated from a combination of the root word entries phonemic data and phonemes generated from rule set processing, then the other entries are indicated to be deleted from the dictionary. After all words have been processed by phase one and/or phase two, the entries indicated to be saved are aggregated to form a reduced dictionary.
