The present invention relates to a clamp. In order to prevent the removal of a wrist strap attached to a device by means of two ends, the clamp (1) comprises at one end a strap closure with a buckle (11) and a closing pin (12), while the other end is provided with a longitudinal row of holes (13) for receiving the closing pin. The clamp is configured to be slid over the buckle while the wrist strap is closed, said clamp being provided with a cover side (2) and comprising at least two lateral sides (3,4), and at least two legs (8) being placed on the inside of the cover side of the clamp and being directed inwardly in order to form an angle with the cover side.
The present invention pertains to a master node for use in a network including a Bluetooth LE link, said master node being adapted to receive, via said Bluetooth LE link, bandwidth reservation request messages including a minimum desired transmission window length and a maximum desired transmission window length; and schedule transmission windows for respective transmitters on said Bluetooth LE link in accordance with said minimum desired transmission window length and said maximum desired transmission window length advertised in said respective bandwidth reservation request messages, said scheduling being performed so as to minimize overlap between assigned values of said transmission windows. The invention also pertains to a network and to an electronic device.
The invention pertains to a connection unit for connecting a plurality of medical devices to a nurse call network, the connection unit comprising: a plurality of medical device interfaces, adapted to receive respective cables connecting to respective ones of said plurality of medical devices; a network interface, adapted to connect to said nurse call network; a control interface; electronic circuitry, operatively connected to said plurality of medical device interfaces, said network interface, and said control interface, said electronic circuitry being configured to: monitor receipt of device alarm signals and losses of connectivity at said plurality of medical device interfaces; relay received device alarm signals and detected losses of connectivity to said nurse call network over said network interface; and selectively activate and deactivate said monitoring and said relaying upon receipt of predetermined control signals over said control interface; and an authentication unit interface configured for receiving, for one or more of said plurality of medical device ports, a delayed activation command.

The invention refers to a method of using a tag in a localisation system, the method comprising at said tag operating a magnetic induction signal detection circuit to detect signals, and upon detection of a magnetic induction signal comprising a first identification code: correlating the magnetic induction signal comprising said first identification code to an ultrasound signal comprising a second identification code, received via an ultrasound signal detection circuit. If said correlation reveals an association between said first identification code and said second identification code: a radio frequency announcement signal is transmitted via a radio frequency signal transmitter circuit to signify said association. The invention also refers to a method of using a beacon in said localisation system, as well as the localisation system comprising one or more tags and one or more beacons.
