Described is an arrangement including a receiver (605) and an enveloped detection arrangement (540) . The receiver receives radio frequency signals generated according to a predetermined wireless communication protocol . The envelope detection arrangement screens the radio frequency signals for a predetermined signal which utilizes the predetermined wireless communication protocol and has a predetermined envelope sequence. Upon detection of the predetermined signal, the arrangement transmits a further signal to a computing device (600) coupled thereto. The further signal is an instruction for the computing device to wake up.
La présente invention concerne un dispositif comprenant un récepteur (605) et un dispositif de détection d~enveloppe (540). Le récepteur reçoit des signaux de fréquence radio générés selon un protocole de communications sans fil prédéterminé. Le dispositif de la détection d~enveloppe recherche dans les signaux de fréquence radio un signal prédéterminé qui utilise le protocole de communication sans fil prédéterminé et qui a une séquence d~enveloppe prédéterminée. Lors de la détection du signal prédéterminé, le dispositif transmet un autre signal à un dispositif de calcul (600) qui lui est couplé. Le signal supplémentaire est une instruction de réveil du dispositif de calcul.
