Abstract

An event sensor circuit monitors power consumption patterns of a device to determine occurrence of particular operations by the device. In response to detection of one or more particular operations the event sensor signals an alert generator to generate an alert. The system may be implemented within a replaceable battery pack or in an add-on package to monitor power consumption of the device and generate an alert. The event sensor circuit and alert generator utilizes a microprocessor which can be programmed to accommodate pattern detection in a variety of devices. The event sensor circuit and alert generator can be used as an alternative or supplemental alert signal source for a device and can be user selectively enabled or disabled and user selectively set to provide a variety of alert signals. The alert generator can be user programmable to provide a fully customized alert.

Claims

1. In a battery-powered system comprised of a portable electronic device for performing one or more functions and a battery for powering the portable electronic device, an apparatus for providing an alert, comprising:

an event sensor for sensing one or more characteristic power consumption patterns having specific frequencies associated with operation of a component of the device, wherein the sensed characteristic power consumption patterns relate to the occurrence of the one or more functions of the device;

the event sensor includes a pattern recognition circuit for evaluating the frequencies of the one or more characteristic power consumption patterns to identify the occurrence of the one or more functions of the portable electronic device; and

,

an alert generator for generating an alert upon the detection of the one or more characteristic power consumption patterns, relating to the occurrence of the one or more functions of the portable electronic device, sensed and evaluated by the event sensor; and

wherein the alert provides an individual with a notice of the occurrence of the one or more functions of the portable electronic device.

2. The apparatus according to claim 1, wherein the event sensor and alert generator are located in a battery pack.

3. The apparatus according to claim 1, wherein the event sensor and alert generator are located in a housing for the device.

4. The apparatus according to claim 1, wherein the event sensor and alert generator are located in a housing separate from the device and battery.

5. The apparatus according to claim 1, wherein the pattern recognition circuit is a microprocessor programmed with pattern recognition software.

6. The apparatus according to claim 1, further comprising:

an on/off element for selectively activating and deactivating the apparatus.

7. The apparatus according to claim 1, further comprising:

a mode element for selectively activating one or more characteristics of the alert.

8. The apparatus of claim 1, wherein the alert generator comprises:

a vibrating alert.
