Abstract: An integrated multichip memory module structure and method of fabrication wherein stacked semiconductor memory chips are integrated by a controlling logic chip such that a more powerful memory architecture is defined with the appearance of a single, higher level memory chip. A memory subunit is formed having N memory chips with each memory chip of the subunit having M memory devices. The controlling logic chip coordinates external communication with the N memory chips such that a single memory chip architecture with N × M memory devices appears at the module's I/O pins. A preformed electrical interface layer is employed at one end of the memory subunit to electrically interconnect the controlling logic chip with the memory chips comprising the subunit. The controlling logic chip has smaller dimensions than the dimensions of the memory chips comprising the subunit. A lead frame, having an inner opening extending therethrough, is secured to the electrical interface layer and the controlling logic chip is secured to the electrical interface layer so as to reside within the lead frame, thereby producing a dense multichip integrated circuit package. Corresponding fabrication techniques include an approach for facilitating metallization patterning on the side surface of the memory subunit.

Abstract: A method and system for maintaining a routing path between a selected workstation (18) and a mobile workstation (36) within a multisegment local area network (10) wherein individual segments (12,14,16) are interconnected by a router device (28,30) and wherein selected segments (14,16) include radio frequency transceivers adapted to provide a wireless communications link with mobile workstations (36). Each time communication is established between a mobile workstation (36) and a selected workstation (18), two routing table entries are established which identify a segment location (14) for the mobile workstation (36) and a segment location (12) for the selected workstation (18) within a routing table (86,84) associated with each router device (28,30). Thereafter, all routing table entries which identify the segment location (14) for the mobile workstation (36) are automatically deleted in response to a termination of communications between the mobile workstation (36) and the radio frequency transceiver. Routing path determination does not require the maintenance of routing path information at each workstation within the multisegment local area network.

Abstract: The invention relates to an innovation, important for engine research, for compensating the thermal shocks superimposed on the pressure cycles. For this purpose, a diaphragm construction is proposed which consists of an annular plate (14) and a central plate (35), which are connected to an annular carrier (9) in such a way that a bridge bearing structure is produced which has a double-parallelogram support. The central plate, which can be optimised in terms of position and thickness, is used as actuator element for controlling the compensation process via the double-parallelogram structure. At the same time, the central plate is raised to a significantly higher temperature level by means of the controlled thermal conduction paths. As a result of these two measures, an innovative thermal shock compensation is achieved. Additional improvement is possible by means of the stepwise optimisation of the central plate, for example by machine-turning the same and comparing it in the test engine. <IMAGE>

Abstract: A pulse-based cable attenuation measurement system provides a measurement of attenuation characteristics of a cable over a wide frequency spectrum. 
     A main test and troubleshooting unit of a cable test instrument applies stimulus signals via a selected one twisted pair in a LAN cable to a pulse receiver in a remote unit that in turn causes a pulse generator to produce a specified pulse of known amplitude and duration that is applied as a measurement pulse to a separate but adjacent twisted pair within the same bundle or cable. A measurement system analyzes the measurement pulse after it reaches the main unit, and provides attenuation versus frequency information to determine whether the amount of signal loss due to attenuation in the cable is acceptable or not.

Abstract: The dynamic range of a current transformer (CT) (17) is increased without reducing the scaling of measurements at the low end of the dynamic range by designing the core (19) of the CT (17) to saturate only after about 90 electrical degrees of the maximum current to be measured. The measurements taken during this first 90 electrical degrees before the core saturates are doubled to in effect add measurements representing the mirror image of the first 90 electrical degrees. Timing of the digitized samples taken during the first 90 electrical degrees is adjusted to account for core reset energy errors, by determining the rate of change of current just after a zero crossing and selecting an empirically determined value of current for timing the start of the measurement samples.

Abstract: Apparatus and methods for reducing the amount of computation required to determine the consequences of a side effect resulting from a transaction on a relation in a data base system use equational reasoning based on a bag algebra representation of a class of transaction and the relation to produce a pre-expression which describes the side effect. The pre-expression is included in the data base system's data dictionary, and when a transaction of the class is received in the data base system, the pre-expression is used to determine the side effect. The pre-expression is formed with a strongly-minimal pair of delete and insert bags. The apparatus and methods may be used to maintain materialized views, to check for violation of constraints on the data base, and to activate triggers, monitors, and active queries.
