Abstract

An electronic communication apparatus comprising an electronic communication apparatus comprising a control unit with a digital processor electronically coupled to an infrared sensor and to a wireless near field magnetic transceiver for communication with a portable electronic device. The infrared sensor is configured for detection of infrared radiation in a selected area in the vicinity of the detector and for creating an activity signal upon detection of movement of an infrared radiation source in the area. The activity mode implies causing the transceiver to transmit a wireless data signal as a request for receiving a wireless response signal with an ID from a portable electronic device.

2. An electronic communication apparatus according to claim 1, wherein the control unit is configured, upon receiving the ID of the portable device by the transceiver, to submit the ID of the portable electronic device as a digital signal to a central computer.

3. An electronic communication apparatus according to claim 1, wherein the control unit is provided with an ID list and is configured to compare the received ID with the ID list, and wherein the control unit is configured only to automatically submit an alarm or the ID of the portable electronic device or both as a digital signal to a central computer, if the received ID is not found in the ID list.

4. An electronic communication apparatus according to claim 1, wherein the control unit is configured upon lack of receiving an ID of a portable device to automatically submit a digital alarm signal to a central computer.

5. An electronic communication apparatus according to claim 1, wherein the control unit is programmed for controlling whether an activity signal is created by the infrared sensor within a predetermined time period, and wherein the control unit is configured to transmit an alarm signal to a central computer if no activity signal is created.

6. An electronic communication apparatus according to claim 1, wherein control unit is programmed for

minimizing the power consumption of the electronic communication apparatus, including causing a sleep mode of the transceiver when no activity signal is received from the infrared sensor,

changing the sleep mode into an activity mode for a predetermined period of time, as a response to the activity signal from the infrared sensor,

causing the transceiver to transmit the request for receiving signal only when in the activity mode.

7. An electronic communication apparatus according claim 1, wherein the infrared sensor is provided in a housing and the selected area is defined by an aperture in the housing and confined to a conical tunnel of sight from the infrared sensor.

8. An electronic communication apparatus according claim 7, wherein the housing comprises a cover with a plurality of apertures and comprises fastening means for fastening the cover in different preselected orientations, each preselected orientation implying a positioning of one selected of a plurality of apertures in front of the infrared sensor, the different apertures defining different tunnels of sight.

9.
