1: Impeller, made of plastics, having a closed construction form, for centrifugal pumps, particularly for use in motor vehicle cooling systems, wherein the impeller is a one part plastic part, whose width of the blade channel, in the meridian section, continuously increases from the flow entry into the impeller to the flow exit out of the impeller, in such a manner that the ratio of the exit width (b2) to the entry width (b1) lies in the range between 1.01 and 1.2.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A system for determining usage of consumer energy at a commercial establishment by a user occupying the commercial establishment and generating loyalty points to be awarded to the user and to be redeemed by the user at the commercial establishment, said system comprising;
a first device for tracking actual use of consumer energy with said first device positioned at premises of the commercial establishment to calculate amount of consumer energy used by the user as the user occupied the premises;
a second device for storing predetermined information about average use of the consumer energy including at least one of size of the premises, geographic location of the premises, number of users occupying the premises and type of consumer energy;
a third device for receiving contact information from the user as the user checks in to the commercial establishment in order to occupy the premises,
a central processing unit operably communicated with said first, second, and third devices for receiving information about said average use from said second device and comparing said average use with information about actual use of consumer energy received from said first device about said amount of consumer energy used by the user as the user occupied the premises; and
a forth device cooperable with said central processing unit for generating loyalty point in response from information provided by said central processing unit as said central processing unit identifies if said actual use matches said average use and falls below said average use and awarding said loyalty points to the user thereby allowing the user to further redeem said loyalty points at the commercial establishment thereby saving consumer energy at the commercial establishment.
2. A system as set forth in claim 1, wherein said first device for tracking actual use of consumer energy positioned at premises of the commercial establishment to calculate amount of consumer energy used by the user as the user occupied the premises is further defined by a fluid usage meter and an electric energy usage meter.
3. A system as set forth in claim 2, wherein said second device is further defined by a database device including information about size of each premise, average amount of electricity and water to be used at the premises based on a season and number of the users occupying the premises.
4. A system as set forth in claim 3, including a global positioning system (GPS) cooperable with said central processing unit to allow said GPS to alert the user who earned said loyalty points about offers available to the user as the user is positioned near any other commercial establishment where said loyalty points were earned and can be redeemed and alerting the user about the offers.
5. A computer generated method for determining usage of consumer energy at a commercial establishment by a user occupying the commercial establishment and generating loyalty points to be awarded to the user and to be redeemed by the user at the commercial establishment, said method comprising the steps of;
interconnecting a first device and a second device to track actual use of consumer energy positioned at premises of the commercial establishment to calculate amount of consumer energy used by the user as the user occupied the premises and storing predetermined information about average use of the consumer energy including at least one of size of the premises, geographic location of the premises, number of users occupying the premises and type of the consumer energy;
connecting a third device to the first and second devices to receive contact information from the user as the user checks in to the commercial establishment in order to occupy the premises,
connecting a central processing unit to the first, second, and third devices to receive information about the average use from the second device to compare the average use with information about actual use of consumer energy received from the first device about the amount of consumer energy used by the user as the user occupied the premises; and
connecting a forth device to the central processing unit to generate loyalty point in response from information provided by the central processing unit as the central processing unit identifies if the actual use matches the average use and falls below the average use thereby awarding the loyalty points to the user to allow the user to further redeem the loyalty points at the commercial establishment to save consumer energy at the commercial establishment.
6. A method as set forth in claim 5, wherein interconnecting a first device and a second device to track actual use of consumer energy positioned at premises of the commercial establishment thereby calculating amount of consumer energy used by the user as the user occupied the premises and storing predetermined information about average use of consumer energy including at least one of size of the premises, geographic location of the premises, number of users occupying the premises and type of consumer energy is further defined by connecting a fluid usage meter and an electric energy usage meter to the first device.
7. A method as set forth in claim 5, wherein interconnecting a first device and a second device to track actual use of consumer energy positioned at premises of the commercial establishment thereby calculating amount of consumer energy used by the user as the user occupied the premises and storing predetermined information about average use of consumer energy including at least one of size of the premises, geographic location of the premises, number of users occupying the premises and type of consumer energy is further defined by connecting a database device including information about size of each premise, average amount of electricity and water to be used at the premises based on a season and number of the users occupying the premises.
8. A method as set forth in claim 5, including the step of connecting a global positioning system (GPS) to the central processing unit to allow the GPS to alert the user who earned the loyalty points about offers available to the user as the user is positioned near any other commercial establishment where the loyalty points were earned and can be redeemed and alerting the user about the offers.
