Abstract

An electronically controlled inflating apparatus for inflating an inflatable bladder with inflating product, the inflating apparatus comprising: an actuator which upon activation is adapted to cause the inflatable bladder to be filled with inflating product; a sensor assembly operatively associated with the actuator, the sensor assembly including a first pressure sensor assembly and a second pressure sensor assembly, the actuator adapted to cause inflation of the inflatable bladder responsive to measurements taken by the sensor assembly, and a control module operatively associated with the sensor assembly, the control module including a switch to place the inflating apparatus in an instant activation mode of operation and a swim activation mode of operation respectively, whereby (i) in the instant activation mode the actuator is activated upon the first pressure sensor assembly detecting a first preset pressure, and (ii) in the swim activation mode the actuator is activated upon (a) the second pressure assembly detecting a second preset pressure and (b) a preset time interval is measured by a timer of the control module after the second pressure sensor assembly has detected the second preset pressure.

Claims

1. An electronically controlled inflating apparatus for inflating an inflatable bladder with inflating product, the inflating apparatus comprising:

an actuator which upon activation is adapted to cause the inflatable bladder to be filled with inflating product;

a sensor assembly operatively associated with the actuator, the sensor assembly including a first pressure sensor assembly and a second pressure sensor assembly, the actuator adapted to cause inflation of the inflatable bladder responsive to measurements taken by the sensor assembly, and

a control module operatively associated with the sensor assembly, the control module including a switch to place the inflating apparatus in an instant activation mode of operation and a swim activation mode of operation respectively, whereby

(i) in the instant activation mode, the actuator is activated upon the first pressure sensor assembly detecting a first preset pressure; and

(ii) in the swim activation mode, the actuator is activated upon (a) the second pressure assembly detecting a second preset pressure; and

(b) a preset time interval is measured by a timer of the control module after the second pressure sensor assembly has detected the second preset pressure.

2. An electronically controlled inflating apparatus according to claim 1 wherein the first pressure sensor assembly comprises a first and a second pressure sensor.

3. An electronically controlled inflating apparatus according to claim 2, wherein the first and the second pressure sensors are configured such that in the instant activation mode the actuator is only activated upon both the first and the second pressure sensors detecting the first preset pressure.

4. An electronically controlled inflating apparatus according to claim 3, wherein the first and second pressure sensors are first and second pressure switches.

5. An electronically controlled inflating apparatus according to claim 1, comprising a motion sensor to detect movement of the electronically controlled inflating apparatus.

6. An electronically controlled inflating apparatus according to claim 5, wherein the control module has a sleep state and an active state and wherein the motion sensor is operatively associated with the control module such that the control module is placed in the active state upon the detection of motion by the motion sensor.

7. An electronically controlled inflating apparatus according to claim 1, comprising a water sensing assembly operatively associated with the first pressure sensor assembly and configured to place the first pressure sensor assembly in a standby mode upon the detection of water by the water sensing assembly.

8. An electronically controlled inflating apparatus according to claim 7, wherein the water sensing assembly comprises a first and a second water sensing circuit and wherein the first pressure assembly is only placed in the standby mode upon both the first and second water sensing circuits detecting water.

9. An electronically controlled inflating apparatus according to claim 1, wherein the actuator comprises a servomotor.

10. An electronically controlled inflating apparatus according to claim 9, wherein the inflating product is stored in a cylinder operatively associated with the servomotor and whereby activation of the servomotor causes inflating product to be released from the cylinder to inflate the bladder.

11. An electronically controlled inflating apparatus according to claim 10, wherein the servomotor is attached to a pin which upon activation of the actuator is adapted to pierce the cylinder to release inflating product.

12. An electronically controlled inflating apparatus according to claim 10, wherein the servomotor is attached to a pin which upon activation of the actuator is adapted to open a valve of the cylinder to release inflating product.

13. An electronically controlled inflating apparatus according to claim 1, wherein the actuator upon activation triggers a chemical reaction to produce inflating product.

14. An electronically controlled inflating apparatus according to claim 1, comprising a manual activation handle having a manual activation circuit in electrical communication with the actuator, the manual activation circuit being in an open condition until a user applies a pulling force to the manual activation handle, such pulling force causing the activation circuit to be closed so as to activate the actuator.

15. An electronically controlled inflating apparatus for inflating an inflatable bladder with inflating product, the inflating apparatus comprising:

an actuator which upon activation is adapted to cause the inflatable bladder to be filled with inflating product;

a sensor assembly operatively associated with the actuator, the sensor assembly including a first pressure sensor and a second pressure sensor;

a water sensing assembly operatively associated with the first pressure sensor and the second pressure sensor, the water sensing assembly being configured to place the first pressure sensor and the second pressure sensor in a standby mode upon the detection of water by the water sensing assembly,

wherein the actuator is activated after the first and second pressure sensors have been placed in the standby mode and upon the first and second pressure sensors detecting a preset pressure.
