  • Patent number: 10834515
    Abstract: A television and a home cinema device work together in various embodiments to render an audio signal including at least a left channel, a right channel and a center channel. The left and right channels are rendered by left and right speakers coupled to the home cinema device, while the center channel is rendered by the left and right speakers of the television. The television can receive the audio signal, decode and render the center channel and send the audio, possibly reencoded left and right channels, to the home cinema device. The television can also send the audio to the home cinema device the returns the, possibly reencoded, center channel for rendering on the television. Alternatively, the home cinema device can receive the audio signal and provide the possibly reencoded center channel to the television. In an alternative, the center channel can be rendered by a soundbar coupled to the television.

  • Patent number: 10049688
    Abstract: A method of handling telephone on-hold music, provided by a second party to a first party on a telephone connection between the first and the second party, includes detecting on-hold music, and providing, while on-hold music is detected, and to the first party, content from a source that is independent from the second party. A length of the most recently received audio signal originating from the second party is continuously stored. When on-hold music is no longer detected, voice information is retrieved from the stored length of the most recently received audio signal, providing, to the first party, content from a source that is independent from the second party is stopped, and the retrieved voice information is reproduced to the first party, wherein a time offset that corresponds to a time period required for detection of on-hold music is present.

  • Patent number: 8022120
    Abstract: The present invention relates to novel comb polymers which bear poly-C2-C4-alkylene ether side chains A and functional groups B which at a pH of >12 are present in the form of anionic groups on a carbon backbone and also the salts of such comb polymers. The invention also relates to the use of these comb polymers as additives in preparations comprising a mineral binder. The polyalkylene ether side chains A have the following formula: *—U—(C(O))k—X-(Alk-O)n—Y—Z??A.

  • Publication number: 20100091436
    Abstract: A wall mounted display device having user friendly connectors for coupling with one or more remote appliances is described. The wall mounted display includes a connector portion that is moveable with respect to the display device. The moveable connector portion is positioned along a portion of a side of the display device and provides easier access to connectors needed to couple a remote appliance to the display device. Alternatively, the screen of the display device is moveable with respect to a wall to which the display device is mounted. The screen is moveable in a plane substantially parallel with the wall upon which the display device is mounted, pivotable at an angle away from the wall upon which the display device is mounted, or rotatable with respect to an electronics portion of the display device.
