Abstract: A data logging monitoring instrument and related methods are described. One aspect provides a particle counting instrument, including: one or more sensors; a storage system; and a processing system coupled to the storage system, the processing system being configured to accumulate measurement data ascertained via the one or more sensors in the storage system into one or more log files; wherein the one or more log files are stored in a secure file format that is compatible with other non-particle counting instrument information processing device applications. Other embodiments are described.

Abstract: Techniques are provided for controlling overload conditions using two values; an acceptance rate fraction allowed value and an occupancy fraction allowed value. The inventive techniques allow quick response to the sudden onset of overload conditions, are robust enough to be used when processor speeds are increased and compare favorably to known techniques.

Abstract: Overload conditions affecting a processor of a network switch or the like are substantially eliminated, and the processing of traffic is gradually allowed to increase, by inserting, and then monitoring one or more probes which are placed into a queue of the processor. During a given measurement interval, if the number of probes exceeds a threshold then an overload condition exists. This condition is subsequently reduced using “multiplicative decrease” techniques. Conversely, if the threshold is not exceeded and there is little or no chance an overload condition can quickly reappear, traffic is allowed to once again be processed gradually using “additive increase” techniques.

Abstract: A platform for supporting telephone network applications includes Network Interface Units (NIU) for interfacing between the telephone network and the platform. A disk storage system stores voice messages to be sent over the network and voice messages received from the network. Voice messages are conveyed between the NIUs and the disk storage system by Voice Interface Modules (VIM). The platform is installed on a general purpose digital computer and includes an Applications Interface Module (AIM) responsive to an AIM command set including: SEND VOICE MESSAGE, CONNECT CALL, COLLECT DIGITS, INITIATE CALL, TERMINATE CALL, GET MESSAGE NUMBERS and PIVOT CALL. In response to SEND VOICE MESSAGE, a designated message stored on the disk system is sent to the network via the VIM. SEND VOICE MESSAGE has a RECEIVE VOICE MESSAGE option whereby a message is received from the network after the SEND data is transmitted and stored on disk.

Abstract: An interface between a real-time data link and a digital computer system utilizes data buffers between the computer central data storage and the data link. An interface control processor is responsive to a Data Transfer Command set comprising a SEND, a GET, a SET-TAG and a TERMINATE command. The commands include a TAG parameter that is set by the SET-TAG command to group sequences of SEND and GET commands so that logical streams of data are continuously transmitted and received across the interface. The SEND command includes a RECEIVE parameter to initiate the transfer of received data from the data link to the buffers after all data associated with the SEND command has been transmitted. Data transmission and reception operations are terminated by a TERMINATE command with a TAG parameter matching the TAG parameters of the sequence of commands controlling the operations. The SEND, GET and SET-TAG commands are stacked in a command queue and applied sequentially to the control processor.
