Abstract:

An optical structure can include a nanocrystal on a surface of an optical waveguide in a manner to couple the nanocrystal to the optical field of light propagating through the optical waveguide to generate an emission from the nanocrystal. The structure can be configured to restrict propagation of the emission from the nanocrystal along the waveguide.

Abstract:

The management of backup sets based on user feedback techniques include a method, and a system. In some embodiments of these techniques, the method includes receiving an update to a backup set from a first client device. The method further includes analyzing the update made to the backup set. The method further includes updating a default backup set stored in a storage device based on the update to the backup set. This Abstract is provided for the sole purpose of complying with the Abstract requirement rules. This Abstract is submitted with the explicit understanding that it will not be used to interpret or to limit the scope or the meaning of the claims.

Appl. No.:

8/677151

Inventors:

Stanley Kugell - Newton Highlands MA
David Friend - Boston MA

Assignee:

Faxnet Corp. - Boston MA

International Classification:

H04M 1100

US Classification:

37910009

Abstract:

A method for providing a never-busy fax service wherein a customer's fax machine appears to be never busy to a caller. The method avoids loop-back charges which limit the usefulness of present implementations of never-busy fax and allow for a nation-wide never-busy fax service utilizing a server with toll-free inbound phone lines.

International Classification:

G10H 102

US Classification:

84 124

Abstract:

An electronic musical instrument incorporates one or more pressure sensitive push-button controllers actuable independent of the keys or other note selecting elements of the instrument to vary a corresponding number of musical parameters. The specific controllers provide a sensitive, smooth, repeatable parameter variation in response to both the location and the force of the player's touch.

International Classification:

H04M 164

US Classification:

379 89

Abstract:

A method for providing a proactive voice mail service wherein a message is recorded by a voice mail server if the customer's phone line is busy or does not answer and the voice mail server then attempts to deliver the message proactively to the customer. The method avoids loop-back charges which limit the usefulness of present implementations of proactive voice mail and allow for a nation-wide proactive voice mail service utilizing a server with toll-free inbound phone lines.

International Classification:

H04W 8/30

US Classification:

4554261

Abstract:

The present disclosure describes systems and methods for reliable backup of data, by initially providing transcoded, down-sampled, or low resolution versions of media data files for backup when a network has low bandwidth or intermittent connectivity, and subsequently providing the original or high resolution copy to replace the transcoded version, either on a second, faster or more reliable network, or over time on the first network. Accordingly, even with poor network conditions, data may be backed up quickly in a reduced size in case of damage to or loss of the device, providing a “better low resolution than no resolution” safety margin.
