摘要:
A control method, apparatus, and system capable of securely distributing a shared secret network encryption key from a host to a wireless peripheral device. The sharing of the secret network encryption key is accomplished without the intervention of a man-machine interface at the peripheral. Embodiments enable a wireless device to receive and store multiple encryption keys, to select the appropriate encryption key depending on the network in range of the device, and thus to freely associate with multiple networks.

A polling method, apparatus, and system capable to detect the attachment and detachment of Universal Serial Bus (USB) devices in a wireless USB system. A USB hub provides a wired connection to the host, while providing wireless attachment points for its devices. The USB host periodically queries the hub looking for changes in the hub's status register. During each period, the hub sends a polling message through each of its wireless ports, and awaits a response. A peripheral device that wishes to attach to the system responds to the message by sending its unique peripheral address. If a device currently occupies the port, the hub sends out the device's unique assigned address as part of the polling message. If the device is still present, it responds by sending its unique peripheral address. If the host does not receive a response after multiple retries, the device is considered detached. The hub thus determines the status of the ports and updates the appropriate bits in the status register, which is then queried by the host.
摘要:
A method of data transmission according to one embodiment of the invention includes transmitting a plurality of bursts to transmit data, each burst occupying at least one of a plurality of frequency bands. Specifically, a bandwidth of at least one of the plurality of bursts is at least two percent of the center frequency of the burst. In one preferred embodiment, a bandwidth of at least one of the plurality of bursts is at least 100 MHz. In another preferred embodiment, each burst occupies at least one of the plurality of frequency bands, but less than all of the plurality of frequency bands.

The method for configuring at least two devices of a hearing system (10) using a communication channel comprises the steps of a1) providing, using said communication channel, a first (11) of said devices with a request (R1) for the execution (E1) of at least one first configuring command in said first device (11); b1) executing (E1) said at least one first configuring command in said first device (11); a2) providing, using said communication channel, a second (12) of said devices with a request (R2) for the execution of at least one second configuring command in said second device (12); wherein step a2) is started before step b1) is completed, in particular wherein step a2) is completed before step b1) is completed. This way, time can be saved in configuring two or more devices (11;12;13) of a hearing system (10).
摘要:
A wireless communication network system apparatus which provides for isochronous data transfer between node devices of the network, which provides at least one master node device which manages the data transmission between the other node devices of the network, which avoids or reduces interference from other wireless products and which resolves random errors associated with wireless technology including multipath fading. The system provides a communication protocol which shares the wireless transport medium between the node devices of the network, and which provides each node device on the network a designated transmit time slot for data communication.

The present invention relates to an antenna module for a hearing device. The antenna module comprises a hollow core provided with an axial passageway and a winding around the core which is connectable with a hearing device. The antenna module is arranged to be at least partially contained within the ear canal of a user. This enables the antenna to be separated from sources of interference, since it can be positioned inside the ear canal away from hearing device electronics, thus reducing requirements for shielding and/or compensation. The invention further relates to an ear tip and a hearing device comprising such an antenna module.
摘要:
A method for providing sound to at least one user, in which audio signals are captured and transformed into audio data that is transmitted to at least one receiver unit; audio signals are generated from the received audio data and the hearing of the user(s) stimulated thereby; wherein the audio data is transmitted as audio data packets in separate slots of a TDMA frame structure, wherein the transmission unit and the receiver unit(s) are synchronized to form a wireless network, wherein each TDMA frame structure has at least one listening slot during which the synchronized network members do not transmit data and at least one network members listens, and wherein control data is transmitted from an external control device according to a sequence pattern selected according to the duration and periodicity of the listening slot(s) to be received by the at least one synchronized network member during said listening slot(s).
