Abstract

A fall indicating alarm system includes one or more fall sensors and at least one gas sensor coupled to a displaced alarm system which, responsive to an output from a fall sensor, generates an audible or visual alarm indicator. Both local and displaced alarm indicators can be generated.

Claims

1. A system comprising:

a fall sensing device;

an apparatus responsive to an ambient or environmental condition and to an output from the device to produce an indicator of either the airborne condition, or a fall; and

an alarm generating unit, responsive to the apparatus, to generate at least a fall indicating indicium.

2. A system as in claim 1 where the indicium is selected from a class which includes an audible alarm, a visual alarm, or an audible alarm and a visual alarm.

3. A system as in claim 2 where the unit is located local to the apparatus.

4. A system as in claim 3 where a different alarm unit is displaced from the apparatus and is in-part in wireless communication therewith.

5. A system as in claim 1 which includes a housing which carries the device, the apparatus and the unit and where the apparatus includes control circuits coupled to the device and the unit.

6. A system as in claim 1 which includes a bi-directional communication link enabling a remote monitoring system to send a message to the apparatus.

7. A system as in claim 6 where the control circuits include a programmable processor and readable storage wherein a control program is stored and executable by the microprocessor to determine when the fall has occurred and which activates the alarm generating unit.

8. A system as in claim 7 which includes executable instructions, responsive to the determination that a fall has occurred, to communicate that the fall has occurred to a displaced monitoring system.

9. A system as in claim 1 where the fall sensing device comprises at least one of an acceleration sensor, or a position sensor.

10. A system as in claim 9 where the system increases it'"'"'s detection of a serious fall event by temporarily changing selected motion detection parameters after it detects an acceleration beyond a certain threshold, and during a period of altered motion alarm parameters after a possible fall, the apparatus will alarm in the absence of motion for a pre-determined time period.

11. A system as in claim 9 where selectivity to fall events is adjusted over time by altering selected fall and landing thresholds and processing.

12. A system as in claim 1 where the apparatus comprises a gas detector and where the gas detector is portable, and wearable by a user and which includes a housing which carries the device, the apparatus and the unit.

13. A system as in claim 12 where the apparatus includes control circuits coupled to the device and the unit.

14. A system as in claim 13 where the control circuits include a programmable processor and readable storage wherein a control program is stored and executable by the microprocessor to determine when the fall has occurred and which activates the alarm generating unit.

15. A system as in claim 14 which includes executable instructions, responsive to the determination that a fall has occurred, to communicate that the fall has occurred to a displaced monitoring system.

16. An apparatus comprising:

a fall sensor;

a gas sensor; and

control circuits, responsive to outputs from at least the fall sensor to detect the presence of a fall, and generate a fall related indicium.

17. An apparatus as in claim 16 where the control circuits respond to outputs from the gas sensor to detect the presence of a predetermined gas condition, and, to generate a gas concentration related indicium.

18. An apparatus as in claim 17 where the sensors are carried in a common, portable, housing.

19. An apparatus as in claim 18 where the indicia are coupled to an alarm indicating output device.

20. An apparatus in claim 19 where the output device is displaced from the housing.
