Abstract:

Apparatus, and accompanying methods for use therein, for a telephony gateway intended for use, e. g. , paired use, at opposite ends of a data network connection, in conjunction with at each end, e. g. , a private branch exchange (PBX) for automatically routing telephone calls, e. g. , voice, data and facsimile, between two peer PBXs over either a public switched telephone network (PSTN) or a data network, based on, among other aspects, cost considerations for handling each such call and called directory numbers, monitoring quality of service (QoS) then provided through the data network and switching (âauto-switchingâ) such calls back and forth between the PSTN and the data network, as needed, in response to dynamic changes in the QoS such that the call is carried over a connection then providing a sufficient QoS.

C07C 229/00

US Classification:

560 40

Abstract:

H01L 51/52

US Classification:

345174, 257 88, 361749, 257E51018

Abstract:

An electronic device may be provided with a display having a flexible substrate with bent edges. The flexible substrate may have a planar active region that includes an array of light-emitting elements such as organic light-emitting diodes with associated control lines. The flexible substrate may also have inactive regions that lie outside of the active region. The bent edges may be formed from portions of the flexible substrate in the inactive regions. Traces for distributing control signals to the control lines in the active region may be formed in the inactive regions. Corner openings may be formed at the corners of the flexible substrate to accommodate bending of the flexible substrate in the inactive regions. A jumper or a portion of the flexible substrate that lies outside of a corner opening may be used to convey signals between traces on adjoining inactive regions.

US Classification:

345173, 156 60

Abstract:

Touch sensor panels typically include a plurality of layers that can be stacked on top of each other. When the touch sensor panel is used in a bright environment, incident light can hit the interfaces between those layers of the stackup having mismatched refractive indices and can reflect off those interfaces. The light reflected from those interfaces can give rise to the appearance of fringes on the touch sensor panel, which can be visually distracting. In order to reduce the appearance of these fringes, embodiments of the disclosure are directed to the addition of an index matching passivation layer between a conductive layer of traces and an adhesive layer in the touch sensor panel stackup.

Abstract:

Apparatus for an improved ISDN terminal adapter (5) and accompanying methods for use therein. The adapter provides automatic ISDN switch detection, automatic SPID configuration, baud rate unblocking and automatic data compression. Specifically, the adapter automatically detects a type of ISDN switch (480) to which the adapter is connected by analyzing D-channel initialization messages which are received by the adapter from the switch as well as specific responses to ISDN messages sent by the adapter. The switch type value is then used, during SPID determination, in conjunction with a telephone area code of the user, to access an internal database (435) of predefined SPID formats, referenced in terms of particular telephone service areas and switch types, to access the possible SPID format(s) for the ISDN switch. Firmware (460) executing within the adapter, in conjunction with software executing within the DTE, forms one of more SPID(s) appropriate for the switch, queries the switch with each of these SPIDs to select and verify a correct SPID from those formed, and, if necessary, further refine and update the switch type previously determined.
