Patent CA-2177021-A1 (CA)
Inventor: AUZERAIS FRANCOIS M
IPC: E21B47/10
Filed: 1996-05-21
Abstract: Images of rock formations below the earth's surface can be obtained on a microscopic scale. A borehole tool uses a seal to isolate an interval of the formation from borehole fluids which are outside the seal. A probe of the toot engages a wall of the formation and then draws formation fluid from the formation into the interior of the tool. The tool then produces an optical image of the formation which indicates rock texture. The seal can comprise a pad, inflatable packers, compressional packers, or cement plugs. The images of the formation can be obtained with electro-optic imagers such as charge-coupled devices (CCD) or a camera operating in the visible and/or near infrared range, or with ultrasonic transducers operating in the sub-MHz to mid GHz range, for example. The near infrared range provides an optical image of the formation through opaque fluids such as oil based muds or oil itself.

Abstract: A method of the invention detects a machining load acting on a tool during a machining process,  computes estimatingly an abrasion quantity of the tool on the basis of the machining load and a tool abrasion characteristic registered in advance in a memory, and changes automatically a tool position compensation quantity on the basis of the tool abrasion quantity.  The estimating computation of a tool abrasion quantity is performed by, for example, obtaining in advance a tool abrasion coefficient on the basis of a tool abrasion quantity per unit time in case of taking a main spindle load current value as a reference machining current value, and integrating for a machining time the product of a ratio of a main spindle load current value during an actual machining process to the reference current value and said tool abrasion coefficient.

Title: Web-page interface to telephony features
Inventor: HASERODT KURT H
IPC: G06F13/00
Filed: 1997-06-26
Abstract: A method is provided for clients to access server-based telephony features in the Internet or other non-telephony client-server network, in a platform-independent and network-independent fashion and without modification of the clients. A user of a client (101) uses the client's World Wide Web (WWW) browser(113) to download from a WWW server (104) a page (115) that defines a blank feature form that has virtual actuators and associated parameter fields for the telephony features. The user marks up the downloaded page via the WWW browser to indicate feature selection and any feature parameters, and uploads the marked up page to the WWW server. A form-interpreting script (116) executed by the WWW server interprets the marked up page, and the WWW server sends a feature requestthat corresponds to the user's feature selection and user-specified parameters to a telephony feature server (105). The telephony feature server responds to the request by providing the requested feature to the user's client. If needed, the WWW server also requests the client to establish a TCP/IP connection with the telephony feature server.

Patent CA-2211747-A1 (CA)
Title: Electronically controlled wastegate valve
Inventor: ZURLO JAMES R
IPC: F02B37/18
Filed: 1997-08-14
Abstract: An electronically controlled wastegate valve is adjusted so that the pressure drop across a throttle in the engine approaches an adaptively generated, desired throttle pressure reserve value. The desired throttle pressure reserve value is based at least in part on a history of the engine load. In the preferred embodiment, the engine speed is used as a surrogate for engine load to determine the desired throttle pressure reserve value. The desired throttle pressure reserve value is preferably pushed downward over time by use of a constant negative gain term in the electronic controller. In this manner, the wastegate control provides sufficient throttle pressure reserve for satisfactory load acceptance when engine load is fluctuating, yet minimizes throttle pressure reserve to improve engine fuel consumption when the engine load is relatively steady.
