Abstract

Devices and methods for providing emergency information. This emergency information device is a portable unit which may be carried to an emergency site. It is operative in response to parameter entries by the rescuer according to the victim'"'"'s condition to provide sequential procedural displays of medical standard rescue steps for assisting the rescuer in carrying out the correct rescue operation. The standard rescue procedure is stored in a microprocessor which, if necessary, can be re-programmed to update to a new rescue standard procedure. It includes a recall feature operative for reverse searching of any desired step in the display if the condition of the victim changes during the rescue operation. Additionally, distinct tone signals are emitted at selected steps of the rescue operation procedure to assist the rescuer in memorizing and conducting such steps in the rescue.

Claims

1. A device for giving audio instruction comprising:

(a) a controller including a processor and a control program;

(b) a CD player coupled to the controller and operative under the control of the controller;

(c) a plurality of playback selectors coupled to the controller;

(d) an amplifier coupled to the CD player;

(e) a speaker coupled to the amplifier; and

(f) a plurality of individually selectable program selectors for selecting specific programs on a CD to be played, the selectors coupled to the controller, wherein each program comprises plural audio instruction messages comprising steps in a procedure, and playback control information for directing the playback of the audio step messages in a predefined pattern and in accordance with operation of the playback selectors, the playback control information including the location of each audio instruction message on the CD and the order of playback of the audio instructions within the program;

wherein the control program in the controller includes instructions responsive to operation of the playback selectors for using playback control information from the CD to select the next audio instruction message to play.

2. A device as set forth in claim 1, the device having a power-on state and a power-off state, wherein operation of one the program selectors causes the device to be in the power-on state without the operation of a dedicated power switch.

3. A device as set forth in claim 1, the playback selectors including a first selector which after operation the controller causes the playback subsystem to move playback ahead by one audio instruction message, and a second selector which after operation the controller causes the playback subsystem to move playback back by one audio instruction message.

4. A device as set forth in claim 1, wherein the controller is coupled to the amplifier and the control program is responsive to volume control instructions in the playback control information on a CD, and the controller, in response to a volume control instruction for increasing the playback volume causes the amplifier to decrease attenuation.

5. A device as set forth in claim 1, wherein the controller is coupled to the amplifier and the control program is responsive to volume control instructions in the playback control information on a CD, and the controller, in response to a volume control instruction for decreasing the playback volume causes the amplifier to increase attenuation.

6. A device as set forth in claim 1 wherein the program selectors generate DTMF codes.

7. A device as set forth in claim 1 wherein the playback selectors generate DTMF codes.

8. A device as set forth in claim 1 wherein the playback control information on the CD comprise DTMF encoded signals and the control program includes instructions for decoding the DTMF signals.

9. A device as set forth in claim 1 further comprising a light sensor, the light sensor sensing when ambient lighting is below a predetermined level, and causing at least some of the playback selectors and the program selectors to be illuminated.

10. A device as set forth in claim 1, further including a flashlight, wherein the handle has a longitudinal axis and the flashlight is aimed about 90°

from the longitudinal axis of the handle.

11. A device as set forth in claim 1, further including a storage compartment accessible by the user, the storage compartment adapted to receive and secure an extra CD.

12. A device as set forth in claim 1, further including a battery recharger having a standard electrical plug which plugs into an electrical outlet and removably secures the apparatus to the electrical outlet and supports the apparatus.

13. A device for giving audio instruction comprising:

(a) a controller including a processor and a control program;

(b) a CD player coupled to the controller and operative under the control of the controller;

(c) a plurality of playback selectors coupled to the controller;

(d) an amplifier coupled to the CD player;

(e) a speaker coupled to the amplifier; and

(f) a plurality of individually selectable program selectors for selecting specific programs on a CD to be played, the selectors coupled to the controller, wherein the device has a power-on state and a power-off state and operation of one the program selectors causes the device to be in the power-on state without the operation of a dedicated power switch.

14. A device as set forth in claim 13 further comprising a power subsystem comprising a battery pack coupled to a voltage regulator, wherein the voltage regulator delivers power from the battery to other components of the device, the voltage regulator having an enable circuit coupled to the program selectors, wherein operation of the program selectors causes a signal to be sent to the enable circuit to enable the voltage regulator and allow power delivery from the battery.

15. A device as set forth in claim 13, the playback selectors including a first selector which after operation the controller causes the playback subsystem to move playback ahead by one audio instruction message, and a second selector which after operation the controller causes the playback subsystem to move playback back by one audio instruction message.

16. A device as set forth in claim 13, wherein the controller is coupled to the amplifier and the control program is responsive to volume control instructions in the playback control information on a CD, and the controller, in response to a volume control instruction for increasing the playback volume causes the amplifier to decrease attenuation.

17. A device for giving audio instruction comprising:

(a) a controller including a processor and a control program;

(b) a CD player coupled to the controller and operative under the control of the controller;

(c) a plurality of playback selectors coupled to the controller;

(d) an amplifier coupled to the CD player;

(e) a speaker coupled to the amplifier;

(f) a plurality of individually selectable program selectors for selecting specific programs on a CD to be played, the selectors coupled to the controller;

(g) a handle having a longitudinal axis and

(h) a flashlight aimed about 90°

from the longitudinal axis of the handle.

18. A device as set forth in claim 17, further comprising a power subsystem for providing power to the controller, the amplifier, the CD player, the program selectors and the flashlight, wherein the controller, the amplifier and the CD player have a power-on state and a power-off state, and operation of one of the program selectors causes the controller, the amplifier, and the CD player to be in the power-on state without the operation of a dedicated power switch.

19. A device as set forth in claim 18, further comprising a flashlight power switch coupled to the flashlight and the power subsystem, wherein the flashlight power switch turns the flashlight on independent of the power state of the CD player.

20. A device as set forth in claim 17, further including a battery recharger having a standard electrical plug which plugs into an electrical outlet and removably secures the apparatus to the electrical outlet and supports the apparatus.
