Abstract
An electrical power pack may include a first power switch and a cycle control to cycle between the first power switch and a second power switch. An electrical power pack may include a first power switch and a delay element to delay an operation of the first power switch. A power pack system may include a first power switch to operate in response to a constant-on control and a second power switch to operate in response to an automatic control. A power pack system may include a first power switch to operate in response to a manual-on control, and a second power switch to operate in response to an automatic-on control.
Claims27
A method comprising:
- energizing a first load with a first power switch in response to a constant-on control without regard to the detected presence or actions of occupants in a space served by the first load;
- and
- automatically energizing a second load with a second power switch;
- where the first and second power switches are included in one or more power packs;
- where the one or more power packs are adapted to connect the first and second power switches to a building wiring system to control the flow of power from one or more sources outside of the power pack to the first and second loads.
2 more elements
A system comprising:
- a first power switch disposed to energize a first load in response to a constant-on control switch without regard to the detected presence or actions of occupants in a space served by the first load;
- and
- a second power switch disposed to energize a second load in response to an automatic control;
- where the first and second power switches are included in one or more power packs;
- and
- where the one or more power packs are adapted to connect the first and second power switches to a building wiring system to control the flow of power from one or more sources outside of the power pack to the first and second loads.
3 more elements
A method comprising:
- manually energizing a first load with a first power switch;
- and
- automatically energizing a second load with a second power switch;
- where the first and second power switches are included in one or more power packs;
- and where the one or more power packs are adapted to connect the first and second power switches to a building wiring system to control the flow of power from one or more sources outside of the power pack to the first and second loads.
2 more elements
A system comprising:
- a first power switch disposed to energize a first load in response to a manual-on control;
- and
- a second power switch disposed to energize a second load in response to an automatic-on control;
- where the first and second power switches are included in one or more power packs;
- and
- where the one or more power packs are adapted to connect the first and second power switches to a building wiring system to control the flow of power from one or more sources outside of the power pack to the first and second loads.
3 more elements
A method comprising:
- automatically de-energizing a first load with a first power switch;
- automatically de-energizing a second load with a second power switch;
- and
- delaying de-energizing the second load relative to the first load;
- where the first and second power switches are included in one or more power packs;
- and
- where the one or more power packs are adapted to connect the first and second power switches to a building wiring system to control the flow of power from one or more sources outside of the power pack to the first and second loads.
4 more elements
A system comprising:
- a first power switch disposed to de-energize a first load in response to an automatic-off control;
- a second power switch disposed to de-energize a second load in response to the automatic-off control;
- and
- a delay element disposed to delay de-energizing the second load in response to the automatic-off control;
- where the first and second power switches are included in one or more power packs;
- and
- where the one or more power packs are adapted to connect the first and second power switches to a building wiring system to control the flow of power from one or more sources outside of the power pack to the first and second loads.
4 more elements
A method comprising:
- energizing a first load with a first power switch in response to a control;
- energizing a second load with a second power switch in response to the control;
- and
- cycling between the first and second loads in response to the control;
- where the first power switch is included in a power pack;
- and
- where the power pack is adapted to connect the first power switch to a building wiring system to control the flow of power from a source outside of the power pack to the first load.
4 more elements
A method comprising:
- operating a first load with a first power switch in response to a first control;
- and
- delaying operating the first load in response to the first control;
- where the first power switch is included in a power pack;
- and
- where the power pack is adapted to connect the first power switch to a building wiring system to control the flow of power from a source outside of the power pack to the first load.
