Abstract: A communications device for wireless communication with another device, the communications device having a) a first part having a first housing and a first induction coil for providing an inductive coupling to the other device, and b) a second part having a second induction coil adapted to be inductively coupled to said first induction coil and to said other device when mounted on or near said first housing. Provided is a relatively simple mechanical interface for an inductively coupled link between a communications device and another device. The second part is adapted to be detachably attachable to the first housing. An advantage is that no connector is needed whereby a simpler and more reliable device is provided. The consequences of wear of the connector leading to increased contact resistance and/or failure of the electrical connection is avoided.

Abstract: A non-invasive method and apparatus for monitoring the bladder volume in humans or animals. The monitoring measurements are based on the analysis of ultrasound signals from at least two individual ultrasound transducer arrays. Each one individual ultrasound transducer array has a contact face, which is arranged in order to transmit an ultrasonic signal through an abdominal surface of an individual being monitored. The method and apparatus includes the arranging of each individual transducer array on the abdominal surface around an axis which extends from a point on the abdominal surface through a point on or within the urinary bladder. The method and apparatus further comprises that each individual transducer array is arranged to scan the bladder using a two-dimensional scan plane which extends radially from the transducer array through the bladder.

Abstract: The invention relates to the transmission of a signal from a communications device to another device (e.g. a hearing aid) by inductive communication and particularly to a scheme for improving the signal quality at the location of the other device. The object of the present invention is to provide an alternative scheme for improving the quality of inductive communication between two (e.g. portable) devices. The basic idea is to arrange at least two induction coils at an angle to each other in a transmitting device and to apply electrical signals comprising carrier signals comprising a carrier frequency fc to the at least two induction coils, the carrier signals of the two electrical signals being phase shifted relative to each other. An advantage thereof is that a reduced drop out is achieved. The invention may e.g. be used for portable communications devices requiring communication with another device over a relatively short distance, e.g.

Abstract: The invention relates to a method and an apparatus for recording volume in humans or animals. The method is non-invasive, and two or more phased-array ultrasound transducers are used for the recording of the volume of the bladder, which, in a bell or a waistband of a pair of trousers, are positioned on the same circle, whose centre is disposed above the bladder whose volume is to be determined. The transducers are oriented in such a manner relative to the bladder to be measured that the ultrasound signals penetrate the surface of the bladder to some extent perpendicularly to it, thereby optimizing the signal/noise ratio. The apparatus, which forms part of the invention, contains no mechanically movable parts and is therefore sturdy, has a low noise level and may easily be powered by small batteries. The apparatus has a low weight and volume and may be used for long term monitoring of the volume of the bladder of ambulatory or sleeping individuals without appreciable discomfort.
