Abstract: A bed exit detection device (100) according to an embodiment of the present invention is mounted to a privacy rail (11) provided in the vicinity of a bed (10) to be monitored. The device (100) comprises a thermographic sensor (130) and a range sensor (40). The thermographic sensor comprises an array of sensing elements operable to generate an output value matrix from the output signals of each individual sensing element. The device (100) is also provided with a processing unit (150) operable to process the output value matrix of the thermographic sensor (130) and the distance output by the range sensor (140) so as to determine the position of a bed occupant and thereby (10) determine the likelihood of a bed exit event.

Abstract: An assisted living monitor comprising a pulse density modulation microphone to read noise levels and a processing unit operable to process the noise levels of the pulse density modulation microphone so as to detect changes in noise levels indicative of an anomalous event or activity, wherein the pulse density modulation microphone reads peak to peak noise levels to detect changes in noise levels indicative of an anomalous event or activity.
