Abstract
A system in which a sensor unit in the casing of a lantern detects an impact and generates a wireless alert signal and is powered from the battery used to power the light source of the lantern. The sensor unit can be mounted onto the terminals of a battery and held within the cavity of the lantern housing used to house the battery. In this way the sensor unit can be incorporated with the lantern without any modification to the design of the lantern.
Claims22
A lantern for use as a boundary marker and/or with a road marker, the lantern comprising:
- a light source;
- a sensor operable whilst the light source is operating to detect when the lantern has been impacted;
- and
- signal generation means to generate an alert signal in response to the detected impact;
- and
- wherein the sensor and signal generation means are arranged to be powered by a battery used to power the light source.
16-25. (canceled)
A perimeter breach alarm system comprising multiple sensor units located at positions along a perimeter;
- each sensor unit having a sensor to detect when the perimeter proximate that sensor unit has been breached and to produce a signal indicative thereof;
- means to receive the signal from the sensor and to generate a wireless alarm signal;
- and
- an alarm unit adapted to receive the wireless alarm signal from one or more of the sensor units and in response to receiving the wireless alarm signal, to produce an audible or visual alarm.
A method of transmitting data between a first unit and a second unit spaced remotely at positions about a boundary perimeter, comprising:
- providing a perimeter breach alarm system comprising multiple sensor units spaced about the perimeter comprising:
- a sensor for detecting that the perimeter proximate the sensor unit has been breached and signal generation means responsive upon said detection to transmit an alert signal;
- transmitting the data from the first unit to a sensor unit which is proximate the first unit;
- relaying the data between sensor units along the perimeter;
- and
- transmitting the relayed data from a sensor unit to the second unit.
