Battery life indication
First Claim
1. A method of indicating extant battery life, the method comprising the steps of:
- (a) initially determining, over a first duration, a first extant battery life value having a first confidence level;
(b) generating a perceivable indication of said first battery life value;
(c) determining, over a second duration, a second extant battery life value having a second confidence level; and
(d) generating a perceivable indication of said second battery life value after generating the perceivable indication of said first battery life value, wherein said second duration is greater than said first duration, the second confidence level is higher than said first confidence level, and said determination of said first extant battery life value is completed before said determination of said second extant battery life value is completed.

Abstract
A method of indicating extant battery life has the steps of initially determining a first extant battery life value having a first confidence level and generating a perceivable indication of the first battery life value. The method also has the step of determining a second extant battery life value having a second confidence level and generating a perceivable indication of the second battery life value after generating the perceivable indication of the first battery life value. The second confidence level is higher than the first confidence level and the determination of the first extant battery life value is completed before the determination of the second extant battery life value is completed.

9. A method of indicating extant battery life for a battery powered apparatus, the method comprising the steps of:
-
(a) determining a first extant battery life value having a first confidence level during operation of an apparatus in a first mode;
(b) generating a perceivable indication of said first battery life value;
(c) determining a second extant battery life value having a second confidence level during operation of said apparatus in a second mode; and
(d) generating a perceivable indication of said second battery life value after generating the perceivable indication of said first battery life value, wherein the second confidence level is higher than said first confidence level and said first mode places a greater current demand on the battery than the second mode. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A battery-powered apparatus including terminals for connections to a battery, a voltage sensor configured to sense the output voltage of a battery connected to said terminals, an indicator and a processor for controlling the indicator to indicate the extant life of a battery, connected to said terminals, in dependence on the output of the voltage sensor, wherein the processor is configured to:
-
(a) initially determine, over a first duration, a first extant battery life value having a first confidence level on the basis of the output of the voltage sensor;
(b) control the indicator to indicate said first battery life value;
(c) determine, over a second duration, a second extant battery life value having a second confidence level, higher than the first confidence level, on the basis of the output of the sensor; and
(d) control the indicator to indicate said second battery life value after indication of said first battery life value, wherein said second duration is greater than said first duration, and said determination of said first extant battery life value is completed before said determination of said second extant battery life value is completed. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)

25. A battery-powered apparatus including terminals for connections to a battery, voltage sensor configured to sense the output voltage of a battery connected to said terminals, an indicator and a processor for controlling the indicator to indicate the extant life of a battery, connected to said terminals, in dependence on the output of the voltage sensor, wherein the processor is configured to:
-
(a) determine a first extant battery life value having a first confidence level on the basis of the output of the voltage sensor when the apparatus is operating in a first mode;
(b) control the indicator to indicate said first battery life value;
(c) determine a second extant battery life value having a second confidence level, higher than the first confidence level, on the basis of the output of the sensor when the apparatus is operating in a second mode; and
(d) control the indicator to indicate said second battery life value after indication of said first battery life value, wherein said second mode is characterised by a higher current demand being placed on the battery powering the apparatus than that placed on the battery by said first mode. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32)
