摘要:
A loudspeaker comprising a bending wave panel-form acoustic radiator having a first portion and at least one further portion a transducer for exciting bending waves in the radiator, the transducer being coupled to the further portion of the radiator to cause the radiator to radiate an acoustic output, and means confining low frequency radiation to the further portion of the radiator.
摘要:
Audio apparatus (30) comprising a piezoelectric transducer (44) and coupling means (54) for coupling the transducer to a user's pinna (32) whereby the transducer excites vibration in the pinna (32) to cause it to transmit an acoustic signal from the transducer (44) to a user's inner ear, characterised in that the transducer is embedded in a casing (42) of relatively soft material and the casing (42) is mounted to a housing (34) of relatively hard material such that a cavity (48) is defined between the casing (42) and housing (34). A method of designing audio apparatus comprising mechanically coupling a piezoelectric transducer to a user's pinna and driving the transducer so that the transducer excites vibration in the pinna to cause it to transmit an acoustic signal from the transducer to a user's inner ear, characterised by embedding the transducer in a casing of relatively soft material and by mounting the casing to protective housing of relatively hard material such that a cavity is defined between the casing and housing.

A touch sensing device includes a plurality of sensors and an emitting transducer coupled to a touch panel. The transducer induces bending waves in the touch panel. The sensors sense bending waves in the touch panel and generate a bending wave signal responsive to the sensed bending waves. A controller identifies an untouched condition signal responsive to the induced bending waves. The controller compares the untouched condition signal to the bending wave signal, and detects a touch on the touch panel based on the comparison.

A privacy management system is disclosed for when a calling party has a private telephone number. Privacy screening services allow a subscriber to manage and monitor incoming telephone calls, such that unwanted calls are not terminated to the subscriber. When a calling party calls the subscriber to this privacy screening service, the privacy management system manages the call according to whether the calling party number is known and public, known and private, or unknown. If the calling party number is known and public, the call is routed to the subscriber. If, however, the calling party is known and private, an announcement is played to the calling party, asking the calling party for permission to override his or her privacy. If the calling party is unknown, the calling party is asked to record his/her name.

摘要:
A method, system, and computer program product for monitoring performance of a network providing content to an Internet Protocol device are provided. The method includes assigning an Internet Protocol address to a network monitoring system to establish a communication between the network monitoring system and an Internet Protocol device associated with the Internet Protocol address. The method also includes gathering performance data corresponding to the network and providing the Internet Protocol device with access to the performance data corresponding to the network via the Internet Protocol address.
摘要:
The present invention is directed to systems and methods of distinguishing acoustic noise from valid plate contacts in vibration sensitive devices such as vibration sensing touch panels. The energy content of the detected vibration spectrum can be analyzed for features characteristic of noise, for example a higher relative contribution from high frequencies due in part to preferential coupling of above coincidence frequencies over below coincidence frequencies.
