1-184. (canceled)
185. A method implemented by a device, comprising:
generating a purchase price of a purchase;
generating a rounded price;
calculating a round-up amount; the round-up amount being a difference between the purchase price and the rounded price; and
printing an entry in a lottery in which a prize for winning the lottery is proportional to the round-up amount.
186. The method of claim 185, in which generating the rounded price comprises:
rounding up the purchase price to a whole number.
187. The method of claim 185, in which generating the rounded price comprises:
calculating a lowest whole number that is greater than the purchase price.
188. The method of claim 187, in which generating the rounded price comprises:
determining a lowest whole number that is a multiple of five.
189. The method of claim 187, in which generating the rounded price comprises:
determining a lowest whole number that is a multiple of one.
190. The method of claim 185, in which outputting the signal indicative of the upsell comprises:
displaying text explain that the identified upsell may be purchased for the round-up amount.
191. The method of claim 185, in which outputting the signal indicative of the upsell comprises:
displaying text that identifies the upsell and at least one of the round-up amount and the rounded price.
192. An apparatus, comprising:
a processor; and
a memory storage device in communication with the processor,
the memory storage device storing a program which controls the processor to perform the method of claim 185.
193. A method implemented by a device, comprising:
generating a purchase price of a purchase;
generating a rounded price;
calculating a round-up amount; the round-up amount being a difference between the purchase price and the rounded price; and
displaying an offer to exchange the round-up amount for an entry in a lottery in which a prize for winning the lottery is proportional to the round-up amount.
194. An apparatus, comprising:
a processor; and
a memory storage device in communication with the processor,
the memory storage device storing a program which controls the processor to perform the method of claim 193.
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 sonde comprising a side wall, a first end wall at a first end of the side wall, a second end wall at a second end of the side wall, a plurality of first sensors mounted in the first end wall, a plurality of second sensors mounted in the side wall, and the sonde being such that:
(i) the first sensors extend longitudinally of the sonde;
(ii) the first sensors are positioned radially around a longitudinal axis of the sonde;
(iii) the first sensors are water quality sensors;
(iv) the second sensors extend radially outwardly from the longitudinal axis of the sonde;
(v) the sonde has a body which comprises the side wall, the first end wall and the second end wall;
(vi) the body is constructed from at least three separately formed plastics disc-shaped components which are connected together by a threaded housing which extends inside the plastics disc-shaped components, which extends along the longitudinal axis of the sonde, and which has parts which screw together to cause the threaded housing to tighten against the plastics disc-shaped components and thereby connect the plastics disc-shaped components together; and
(vii) the sonde includes an optical sensing arrangement mounted in an optical cavity in the side wall.
2. A sonde according to claim 1 and including a stirrer.
3. A sonde according to claim 2 in which the stirrer is a magnetically coupled stirrer.
4. A sonde according to claim 2 in which the stirrer is mounted in the first end, and in which the stirrer extends along the longitudinal axis of the sonde.
5. A sonde according to claim 1 in which the second sensors include two diametrically opposed thermal mass flow sensors, and at least one water temperature sensor.
6. A sonde according to claim 1 in which the first sensors connect to a printed circuit board which is positioned in the sonde and which extends across the sonde transversely to the longitudinal axis of the sonde.
7. A through flow cell including a sonde according to claim 1.
8. A water distribution network including a plurality of sondes according to claim 1 and arranged to provide measurement information at different locations within the network.
9. A sonde according to claim 1 and including a turbidity sensing arrangement which is mounted in the side wall.
10. A sonde according to claim 1 in which the plastics disc-shaped components are bonded together or separated by compressed gaskets.
