Title: Query optimization in a relational database system.
Inventor: CHAUDHURI SURAJIT
IPC: G06F17/30
Filed: 1994-06-06
Abstract: Database applications typically need to invoke foreign functions or to access data that is not stored in the database. The invention provides a comprehensive approach to cost-based optimization of relational queries in the presence of such foreign functions. The optimization takes into account semantic information about foreign functions using a declarative rule language (e.g., SQL) to express such semantics. Procedures for applying the rewrite rules and for generating the execution space of equivalent queries are described. Procedures to obtain an optimal plan from this execution space are also described. Moreover, necessary extensions to the cost model that are needed in the presence of foreign functions are described. <IMAGE>

Title: A method of vertical integration for microelectronic systems
Inventor: RAMM PETER
IPC: H01L25/065
Filed: 1996-04-30
Abstract: A method of vertical integration for microelectronic systems can be carried out with standard semiconductor technologies compatible with CMOS and makes it possible to reduce the cycle times in manufacture and to increase the yield, compared with known methods. In the method, the individual component layers are processed independently of one another in different substrates (1, 8) and are then joined together. Firstly, vias (7) are opened in the front side of a ready-processed top substrate (1) and penetrate all component layers present. Then a processed bottom substrate (8) is bonded to the top substrate, front face to front face. The top substrate in the substrate stack which now exists is thinned from the rear side, down to the vias (7). Then the opened vias are extended through the remaining layers down to a metallisation plane (11) of the bottom substrate and the electrical contact (15) between the top and bottom substrates is created.

Title: Active variable capacitance control of the input or output impedance of a power rf amplifier to improve efficiency
Inventor: PECKHAM DAVID SUTHERLAND
IPC: H03F1/02
Filed: 1996-05-30
Abstract: A unique method and apparatus modifies the load impedance at the output of a power amplifier by varying a voltage variable capacitor (VVC) 310 to maximize the efficiency of the power amplifier 304. A comparator (509) generates amplifier control signal (211) based upon a detected power output signal (216) and a reference signal. In addition to providing power control, the control signal is also coupled to a VVC circuit (506) to control the output impedance of the power amplifier. In an alternate embodiment, a separate VVC control signal (527) based upon a comparison of the power control signal and the battery voltage is coupled to a VVC. In another alternate embodiment, a second VVC can be coupled in parallel to the first VVC. The second VVC is preferably controlled by a signal (805) based upon the current in the power amplifier. Finally, an alternate embodiment incorporates a VVC circuit (506) at the input of the power amplifier to compensate for variations in input impedance to improve other power amplifier parameters such as IM, gain, output power and noise level.

Title: Productin wells having permanent downhole formation evaluation sensors
Inventor: TUBEL PAULO
IPC: E21B47/01
Filed: 1996-09-11
Abstract: A downhole control system (22) for a production well (19) is associated with permanent downhole formation evaluation sensors (58) which remain downhole throughout production operations, in conjunction with a downhole electronic controller. These formation evaluation sensors (58) may include, for example, neutron generator, gamma ray detector and resistivity sensors which can, in real time, sense and evaluate formation parameters including important information regarding formation invading water entering the producing zone. Significantly, this information can be obtained prior to the water actually entering the producing geological formation and therefore corrective action (i.e., closing of a valve or sliding sleeve) can be taken prior to water being produced. This real time acquisition of formation data in the production well (19) constitutes an important advance over current wireline techniques in that the present invention is far less costly and can anticipate and react to potential problems before that occur. In addition, the formation evaluation sensors (58) themselves can be placed much closer to the actual formation (i.e., adjacent the casing or downhole completion tool) than wireline devices which are restricted to the interior of the production tubing.
