摘要:
A hearing system includes a hearing device with a signal processing unit. A control input of the signal processing unit is connected to a device communication port. A remote control device has a wireless communication port for single or bi-directional wireless communication with the device communication port. A computer is embedded in the remote control device. An output of the computer is connected to the wireless communication port and to a machine/man interface at the remote control device. An input of the computer is connected to a man/machine interface at the remote control device. A set of application programs is executable by the computer.

There is provided a method of operating a hearing assistance system comprising a hearing device (10, 110, 210), which comprises means (24) for stimulating a user's hearing and which is worn at one of the user's ears, and a remote device (12, 30, 40) spaced apart from the hearing device. The method comprises: establishing a wireless link (26) between the hearing device and the remote device for transmitting signals from the remote device to the hearing device, and operating the system in a base mode; detecting whether a source (28) of radio frequency signals interfering with the wireless link and having a transmission power changing according to a predictable scheme between low power regimes and high power regimes is present in the vicinity of the hearing device; and operating the system in an interference mode as long as the presence of such source of periodic signals interfering with the wireless link is detected, in which interference mode the transmission of the signals from the remote device to the hearing device is synchronized to the detected power scheme of the interfering signals in such a manner that the signals are transmitted only during the low power regimes.
摘要:
A sensor (1) for determining both a cadence of a crank and a travelling speed of a bicycle includes an accelerometer (4) providing a first signal dependent on a first acceleration along a first measurement axis (z) and a second signal dependent on a second acceleration along a second measurement axis (y) perpendicular to the first measurement axis. The accelerometer (4), a wireless transmitter (6) and a power source (8) are contained in a housing (2) that can be attached to a wheel of the bicycle. The sensor (1) determines the cadence from the rate at which consecutive changes of polarity occur in the first signal, or from the rate at which consecutive positive and negative extreme values occur in the first signal. The sensor also determines the travelling speed from the rate at which consecutive maximum and minimum extreme values occur in the second signal.

The method comprises the steps ofautomatically monitoring and detecting indications indicative of a forthcoming event concerning hearing systems; if such an indication is detected, retrieving identification data identifying at least one device of the hearing system concerned, referred to as specific device, or a user of said hearing system concerned, referred to as specific user; and using said identification data for retrieving further data related to said specific device as device data or related to said specific user as user data. The method and the corresponding system can be used for adjusting said specific hearing system or other support actions, like dispensing consumables for said specific hearing system, or preparatory actions, like launching a suitable fitting program or loading audiological data related to the user.
