Abstract: An interface allowing to transfer serial test data from a Test Access Port (TAP) to controllers located in several clock domains is described. The clock frequencies can be different from each other and do not need to be related in phase to each other or with the clock of the TAP. The interface is proven to work reliably as long as the clock frequencies used for the test controllers and registers is 3 times higher than the one of the TAP used to source the serial test data.

Title: Method and apparatus for voice interaction over a network using parameterized interaction definitions
Inventor: RAMMING JAMES CHRISTOPHER
IPC: H04M3/42
Filed: 1998-04-03
Granted: 2003-01-07
Abstract: An audio browsing adjunct executes a voice markup language browser. The audio browsing adjunct receives a voice interactive request. Based on the request, the network node obtains a document. The document includes a voice markup, and a parameterized interaction definition or at least one link to a parameterized interaction definition when user interaction is required. The audio browsing adjunct interprets the document in accordance with the parameterized interaction definition. By using the parameterized interaction definition, entered data is typically verified at the audio browsing adjunct instead of at a network server. Further, the parameterized interaction definition can define a finite state machine. When it does, the parameterized interaction definition can be analyzed so that performance problems of the audio browsing adjunct are minimized.

Title: Horizontal-flow oil-sealant-preserving drain odor trap
Inventor: GORGES DITMAR L
IPC: E03C1/28
Filed: 1996-10-25
Granted: 2002-01-08
Abstract: Improvements in retention of the oily liquid sealant (20) in an oil-sealed odor trap (10B), for drain applications such as a waterless urinal or anti-evaporation floor drain, are accomplished by making the liquid flow path (22A, 22B) substantially horizontal as a departure from conventional practice of substantially vertical flow. The trap (10B) is structured to realize the substantially horizontal liquid flow path (22A, 22B) and to locate the flow path immediately beneath the sealant layer (20) or beneath a baffle portion (16B) that is sloped such that stray sealant droplets migrating upwardly to the upper surface of the flow path due to their buoyancy will be recaptured and returned to the main sealant layer (20). To accomplish substantially horizontal flow (22A, 22B), the entry compartment can be made to have entry (16D) and exit openings substantially offset from each other. The baffle between the entry compartment and the discharge compartment, which has traditionally been made entirely vertical, is made to have a non-vertical portion (16B) that is preferably sloped for sealant recovery. A sealant sheltering region can be provided in the vicinity of the entry region to prevent catastrophic loss of sealant in the event of high pressure water flushing.

Abstract: A system for producing a flow of fine snow particles includes a conduit for providing a pressurized flow of a cryogenic liquid and a nozzle coupled to the conduit, the nozzle having an outlet and an inlet pathway in communication with the conduit.  An expansion member is positioned within the nozzle and covers the inlet pathway.  The expansion member provides multiple fine channels for passage of the cryogenic fluid into a region of lower pressure, thereby enabling expansion of the cryogenic fluid during passage through the expansion member.          In a preferred embodiment, the cryogenic fluid is carbon dioxide and the system parameters are set to enable the cryogenic fluid to enter a solid phase at or near the outlet surface of the expansion member and to exit therefrom as a fine snow particulate.

Title: System and method for activation of an enhanced telecommunication service
Inventor: MALIK DALE W
IPC: H04M3/42
Filed: 1998-10-26
Granted: 2002-05-14
Abstract: A system and method for activation of an enhanced telecommunication service without a turn-on call by a subscriber. The present invention is described in the AIN environment, where an enhanced telecommunication service is set up for a directory number. The enhanced telecommunication service has an active state wherein the enhanced telecommunication service is applied to calls received for the directory number. The enhanced telecommunication service also has an inactive state wherein the enhanced telecommunication service is not applied to calls received for the directory number. The first call is directed to the directory number, where the enhanced telecommunication service is in the inactive state. A no answer condition from the directory number is detected with respect to the first call. In response to the detection of the no answer condition, the enhanced telecommunication service changes to the active state. The enhanced telecommunication service is maintained in the active state for successive calls, whereby the enhanced telecommunication service is activated by the detection of the no answer condition for the first call, without the turn-on call from the subscriber, and remains activated for successive calls to the directory number.

Granted: 2003-11-18
Abstract: An optical device having a large extinction ratio and being suitable for the digital operation including first and second electrodes (7, 8) formed on both sides of a waveguide structure, respectively such that a carrier-injection region (3a) and a non-carrier injection regions (3b) are formed adjacent to each other in the waveguide structure. When mass carriers are stored in the carrier injection region, its refractive index is reduced lower than the non-carrier-injection regions. In this state, when a light wave with low optical power propagates through the carrier-injection region, since an amount of carriers consumed thereby is small, the refractive index of this region is still lower than the non-carrier-injection regions, and the input light wave is emitted sideways through the non-carrier-injection region. In contrast, when a light wave with high optical power propagates through the carrier-injection region, since the carrier consumption is large, the refractive index of this region (3a) becomes higher than the non-carrier-injection regions (3b), and the input light propagates through a waveguide which is optically induced to extend from the incident surface to the exit surface.
