Consumption control apparatus has a rate meter operative for determining an actual rate at which an arm of a user is brought into an eating position during a consumption session, and an indicator operative for providing a sensible indication whenever the actual rate deviates unacceptably from a preselected, standard, eating rate. The apparatus preferably provides the user, during preselected learn/practice time intervals, with a sensible indication corresponding to the preselected standard rate....

A portable device helps a person control food consumption to eat in a more relaxed manner so time is provided for the "appestat" in the human brain to signal the person that he/she is full before overeating, and to provide time for conversation when eating with others. The apparatus includes red and green lights (22, 20), a circuit (46) that controls energization of the lights, and a pushbutton switch (42) that operates a portion of a circuit. When the push button (44) is depressed the circuit e...

A fuel consumption meter for a motor vehicle comprises a bubble separating vessel and a fuel flow meter connected in series in the main pipeline between the fuel pump and a fuel supply member of the vehicle. The bubble separating vessel has an air vent valve, a float for measuring specific gravity and a thermometer. An auxiliary pipeline connected in parallel with the portion of the main containing the bubble separating vessel and the fuel flow meter provides a circulating circuit in which an el...

Electric signals, corresponding to two or more engine operating parameters, such as rotational speed of the engine drive shaft and the setting of the throttle valve or a rotational speed and the pressure in the intake manifold or the pressure in the intake manifold and the setting of the throttle valve, are obtained by transducers, these signals being fed to an evaluating circuit that produces an electric output that is conducted to a meter that reads fuel consumption in unit distance, or unit t...

Apparatus and methods are described for measuring fuel consumption of an engine accelerating at constant load. The arrangements disclosed provide for detecting a plurality of predetermined engine rpm speeds and for generating a condition when each of said speeds is reached. In response to these conditions, the arrangements register and store an indication of the quantity of fuel per unit time being consumed at each of the plurality of speeds. The arrangements are controlled so that the measureme...

A device for measuring the consumption of fluid in equipment including a pump, said device comprising a component connected, on the one hand, to a movable part of the pump and, on the other hand, to a rotatable shaft by means of an intermediary member which may be a motion converter. The rotatable shaft is under the influence of a member which locks it in one direction and is connected to a mechanism which includes a revolution counter and a mechanical motion converter which generates electrical...

A method and apparatus for consumption of content (1) is described in which a licensor is able to exercise control over consumption based on a personal identity in the form of a set of binding attributes (15). The control may be exercised for a number of consuming terminals (19) including rendering machines such as portable video and audio players.

A meter for monitoring consumption of a resource, such as water or other fluids, and corresponding methods of configuring and operating the meter are disclosed. The meter includes processing and memory devices for determining and storing a supplier measure of consumption of the resource and a communication link for enabling a supplier to access the stored supplier measure. The supplier access is controlled by a first access control device, which prevents unauthorized access to the stored data. T...

A fuel meter for trucks having a fuel measuring chamber for measuring by float sensed levels a quantity of fuel and emptying that quantity into a reservoir from which the truck engine draws its fuel, the emptying occurring whenever the fuel level in the reservoir is low. A counter counts the number of times the measuring chamber thus empties in order to compute overall fuel consumption. The meter can be by-passed when out of order.

This invention relates to methods and means of measuring fuel consumption of vehicles propelled by combustion engines, and of stationery combustion engines. This invention relates also to methods and means of generating electrical signal in proportion to the speed of the vehicle, particularly sailboats and sailplanes, whether propelled by an engine or not. In the case of stationery combustion engines, the invention relates to methods and means of generating electrical signal in proportion to the...
