This disclosure proposes an optimization of current technology to take account of user usage patterns so that machine is available for use for a higher percentage of user approaches while not significantly increasing the energy consumption, thus improving the lifetime of the unit.
The current model for power saving in multipurpose office equipment has the following drawbacks:
- Power-up time from stand-by takes time and is a customer dissatisfier
- If in a short period several power-ups occur, the expected product lifetime is reduced more than if the unit was left on full power during that time, since power-up sequences have a high wear factor due to thermal cycling when disabled
- Energy is wasted
- Expected product lifetimes are reduced
This disclosure proposes an optimization of current technology to take account of user usage patterns so that machine is available for use for a higher percentage of user approaches while not significantly increasing the energy consumption, and improving the lifetime of the unit.
The result should be an improved user experience without significant cost to the environment.
Detailed Design Change Proposal:
The following design concept is based on a single standby timer, rather than the two (standby and sleep) which are more commonly used today. Nevertheless, the principle can be applied to both simple and dual timers machines.
The premise of this proposal is that in most office environments there are repeated temporal patterns of usage, in particular related to the time of day, day of the week, time of the month, season. From previous records of usage it is possible to determine these patterns and thereby predict the probability of
a user utilizing the machine.
As a starting point, the manufact...
