Abstract: Blood pressure measurements are represented aurally. An audio synthesizer (15) receives a signal representative of blood pressure information, and synthesizes an audio output from the signal. Both the duration and pitch of the synthesized audio output are dependent on the value of the blood pressure information, according to a linear scale or a non-linear scale such as stepped scale. The blood pressure information includes at least one of arterial or pulmonary arterial systolic, diastolic and mean blood pressure measurements, and the audio output includes an earcon comprising a tone or sequence of tones, the tone(s) being representative of a respective type of blood pressure measurement. The earcon may also include one or more static or dynamic beacons.

Abstract: A combined cellular phone and water-proof casing may include a cellular telephone. The cellular phone may include a display screen and a key pad communicatively coupled thereto. A protective water-proof casing may be connected to the cellular telephone in such a manner that the display screen remains operably responsive to the key pad after the cellular telephone is submerged in water. The water-proof casing may further include a first sheath and a second sheath. The second sheath may further be mated to the first sheath. A gasket may be intermediately intercalated between the first and second sheaths and thereby prevent water from penetrating through the outer edges of the first and second sheaths respectively. A plurality of ports may be formed in the water-proof casing, and a plurality of port covers may be removably interfitted within the ports.

Abstract: The level of consciousness of a patient (i.e. the hypnotic state and/or the level of anaesthesia) is represented aurally. A measure of the patient's level of consciousness, such as the BIS index value, is obtained, and an audio signal is synthesized from that measure, and then output through a speaker. Both the volume and pitch of the audio signal may vary according to the BIS value being represented, so that a clinician can obtain an indication of the level of consciousness of the patient simply by listening to the sonification of the BIS value. The audio signal may comprise first and second audio components, with the first component representing the previous measure and the second component representing the current measure. The amplitude or pitch of the audio signal may be modulated to represent analgesia or paralysis of the patient.
