Abstract
A security system for use on a boat with propulsion means, such as an engine, has a base unit mounted on the boat and a personal unit attached to the driver and each passenger. The base unit has a first radio unit and an RFID-reader with an antenna, and is in wireless communication with the personal unit. The personal unit has an RFID-transponder and a second radio unit, both with a unique identity, and a biometric unit that at correct attachment to the person send a biometric signal to the base unit. The communication utilizes RFID technology within a near range, but the system automatically handovers to radio technology when a larger area is to be covered. A field from the RFID reader activates the RFID-transponder, and if the identity is correct the person is registered as the driver and may start the boat. When the base unit loses communication with a personal unit different measures are initiated, such as activating an alarm.

30. A security system for use in a boat having propulsion means, such as an engine, the system comprising:
-
a base unit mounted on the boat having a first radio unit;
and one or several portable personal unit having a second radio unit with an individual identity for communication with the base unit, wherein each personal unit comprises an RFID (radio frequency identification) transponder having a unique identity, and the base unit comprises an RFID reader having at least one decoder and at least one antenna, wherein the communication between the base unit and each personal unit is performed by the RFID-transponder and the RFID reader when the distance between the base unit and each personal unit is within a first range (A) and by the radio units outside this first range (A) and within a second range (B) that is defined by the range of the second radio unit, the handover being automatic. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48)

49. A method for operating a security system, comprising the steps of:
-
activating an RFID-transponder of the at least one personal unit by an electromagnetic field of a RFID reader of a base unit, said RFID reader defining permitted and/or forbidden areas by the range of said RFID reader;
verifying the activation by sending an RFID signal from the activated RFID-transponder;
establishing a wireless communication between the base unit and the at least one personal unit using RFID-technology within a set range (A) and by using radio-technology outside this range (A), the handover being automatic;
activating an alarm when one of the at least one personal units leaves the permitted areas, enters forbidden areas, or when no signal is detected by the base unit; and
performing a security measure.

50. A base unit for a wireless security system, which is arranged on a boat having propulsion means, such as an engine, comprises:
-
a steering-wheel for steering control of the boat;
a radio unit and a receiver having a decoder;
at least one antenna, which has a circular or partly circular configuration, wherein the base unit is arranged adjacent to the steering wheel. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57)
