摘要： A full-time power transfer system is disclosed to include a transfer case having a clutch assembly arranged to control speed differentiation and torque biasing across an interaxle differential, sensors for detecting and generating sensor signals indicative of various dynamic and operational characteristics of the vehicle, and a controller for controlling actuation of the clutch assembly in response to the sensor signals. Upon the occurrence of traction loss, the clutch assembly is automatically actuated for limiting interaxle slip while transferring increased drive torque to the non-slipping driveline. Under a preferred adaptive control scheme, the actuated condition of the clutch assembly is controllably modulated between its non-actuated and fully-actuated limits for automatically varying the magnitude of speed differentiation and torque biasing across the interaxle differential in response to changes in the dynamic and operational characteristics of the vehicle.

摘要： A transmission for a four-wheel drive vehicle having a multi-speed geartrain and power transfer mechanism incorporated into a common housing assembly. The multi-speed geartrain includes a input shaft, a mainshaft, and a plurality of constant-mesh gearsets arranged for selectively coupling the mainshaft to the input shaft for driven rotation at various speed ratios. The mainshaft can be selectively coupled to the power transfer mechanism for establishing two alternative power transmission routes. In particular, a range shift mechanism is provided for establishing a high-range power transmission route and a low-range power transmission route from the mainshaft to the input of an interaxle differential. The torque delivered to the interaxle differential is split between the front and rear drivelines to establish a full-time four-wheel drive mode. A transfer clutch is provided for automatically controlling slip and torque biasing between the outputs of the interaxle differential.

摘要： In a database data processing system, input search data is matched against an index of a database to determine database records which either closely or exactly match the input search data. The input search data is broken down into elements, and elements are converted to terms having a finite set of possible values. The Soundex function may be used to convert elements to terms. The terms are compared against an index of terms to determine which database records relate to the input search data. Through statistical analysis, match records are given a record weight which may be used to calculate how closely the input data actually is to each match record. The invention provides a fast and efficient way of accurately searching for data in extremely large databases, while not requiring precise input search data entry. The invention may also be used to compare or supplement one database against another.
摘要翻译：在数据库数据处理系统中，将输入搜索数据与数据库的索引进行匹配以确定与输入搜索数据紧密或完全匹配的数据库记录。输入搜索数据被分解为元素，元素被转换成具有有限可能值集合的项。 Soundex函数可用于将元素转换为术语。将这些术语与术语索引进行比较，以确定哪些数据库记录与输入搜索数据相关。通过统计分析，给出匹配记录的记录权重，可以用于计算输入数据实际上与每个匹配记录的接近程度。本发明提供了一种快速有效的方式来精确搜索极大数据库中的数据，同时不需要精确的输入搜索数据输入。本发明还可以用于将一个数据库与另一个数据库进行比较或补充。

摘要： A multi-level stacked mold having at least two and as many as four levels of cavities has a stock distribution mold block centred axially of the stacked mold blocks, the axially extending stock inlet passage to the distribution block connecting with radially off-set stock transfer passages that cross the axially openable mold block interfaces, into the adjoining mold blocks. These openable stock transfer passages, are each provided at their respective, non-encapsulated, radially off-set, opening interfaces with a valveless anti-drool arrangement. The mold flow passage system is subject to continual, extreme, thermal cycling and cyclical mechanical loading, during the repeated opening-and-closing cycles of the mold. Each separable anti-drool sealing interface has a relatively axially displaceable portion extending to bridge the initial gap opening between adjacent mold blocks and serving as an expansible piston means. This extension of the displaceable "expansible piston means" portion is pressure responsive and serves to increase the internal volume of the adjacent transfer passage, while permitting equalizing the pressure of stock in the passage to atmospheric pressure, thus reducing the likelihood of the drooling of liquid plastic into the opening interspace, or the induction of atmospheric air into the flow passages.

摘要： An integrated vehicle dispatch system that performs the management, coordination and communication functions for dispatching vehicles. The system include a plurality of microcomputers interconnected via a "BITBUS" network, such that a fully redundant capability is provided. Each of the workstations control text and or graphics monitors. Information in the graphics monitors are based upon a digitized map base, such as the U.S. Census Bureau GBF file or "DIME File" of the vehicle delivery areas, such that vehicle pickup, deliveries, minimum path routes and vehicles delivery zones are displayed in an icon-based format. The software of the system calculates minimum travel time based upon a tree-node decision algorithm that matches street distances, and travel times to real traffic conditions. Candidate vehicles for pickups and deliveries are selected upon a user-defined set of factors that include time, speed, vehicle characteristics and distance factors. The software also includes a fully integrated third party billing and business operations accounting package that enables fully automated dispatch system operation.

摘要： A pressure sensing device hydraulically coupled with a transducer comprising a closed hydraulic system incorporated within an endotracheal tube to monitor intrapulmonary pressure. The tube employs an hydraulic system for conveying pressure data from a distal sensor, on the tube, to a transducer. The sensor and transducer are connected by a liquid-filled lumen. Use of an hydraulic conduit avoids the errors of gas-filled systems because liquids, such as the water used in this system, are incompressible.
