An inhalation device includes a light source that emits light, a light sensor that senses an intensity of the light emitted from the light source and a processor or circuit configured to perform a metering process. The metering process may include when a signal indicating that a puff has been detected by the puff detecting element: extracting a predetermined known flow rate that is stored in the memory in advance, determining an amount of vaporized substance that have been produced, and accumulating the determined amount of vaporized substance that has been produced in the memory as a total amount produced. The metering method may also include when the accumulated total amount produced reaches a predetermined threshold: (i) shut off the heating element or (ii) send a signal to an indicator that the predetermined threshold amount of the vaporized substance has been consumed.

A content fill level is measured. An interrogation signal is transmitted. A reflected signal having a plurality of peaks is received. One of the peaks corresponds to a signal reflection of the interrogation signal indicative of the content fill level. The plurality of peaks is digitally analyzed to distinguish which peak is indicative of the content fill level.

A drop-detection device detects a drop that escapes from a metering valve. The drop-detection device includes a light guide with first and second light-guiding elements that are arranged opposite each other at an intermediate space. A drop trajectory runs through the intermediate space such that a light beam sent out by the first light-guiding element crosses the drop trajectory and is subsequently coupled into the second light-guiding element. In addition, the drop-detection device includes a light-signal generation device that couples a pulsed light beam with a carrier frequency into the first light-guiding element. Furthermore, the drop-detection device also has a light evaluation device for evaluating the light beam coupled into the second light-guiding element to determine if a drop has been dispensed by the metering valve. A method of detecting a drop is also described.

A wireless metered fluid dispenser brings discrete fluid dispense events inside of a fluid management system. The wireless metered fluid dispenser allows a customer to visually confirm the fluid being dispensed and provides automatic tracking of the fluid dispense event within a wireless tracking system. A volumetric flowmeter attached to the bottom of a container or funnel tracks the amount of fluid dispensed when pouring from a container. The volumetric meter is wirelessly connected to a computer system for the transmission of data, for the purpose of centralized control and billing.

A beverage dispenser comprises a bottle holder, a motor, and a controller. The bottle holder is configured to hold a bottle of a liquid beverage. The motor is connected to the bottle holder and configured to move the bottle holder in an angular movement to bring the bottle into a pouring position. The controller is configured to control the bottle holder via the motor in a set pattern to dispense a portion of the liquid beverage from the bottle into a serving receptacle. The liquid beverage may be wine, and the serving receptacle may be a wine glass. The liquid beverage may be liquor, and the serving receptacle may be a shot glass. The portion of the liquid may be an amount of liquid to fill the receptacle to a designated level. The portion of the liquid beverage is less than the entire capacity of the bottle.

A signaling apparatus paces a free pour count and choreographs a movement to stop pouring. The apparatus emits a first signal after an approximately 200-ms time interval and a series of subsequent signals every approximately 400-ms thereafter. The first time interval approximates a first time, measured from a moment the sensor detects the start of the pour, needed to dispense a first unit of beverage through the pour spout, minus a second time needed to react to a signal and stop the pour. The 400-ms time interval approximates the time required to dispense each subsequent unit of beverage through the pour spout. In one embodiment, the signaling apparatus emits sequential pulses according to the pattern Y-Y-Y-Y-G-Y-Y-R, wherein Y is yellow, G is green, and R is red, wherein each pulse represents a quarter-ounce increment, the green pulse represents a standard pour, and the red pulse represents a full pour.

An external metering valve disposed on a gas fuel tank including an outlet rod is provided. The outlet rod includes an outlet orifice at a front end thereof. The external metering valve includes a metering valve and a gas guiding member. The metering valve includes a metering chamber. The gas guiding member includes a communication pipe, a blocking portion on the communication pipe, a discharging channel and an inlet orifice. The gas guiding member has a sealing outlet position and a metering outlet position. At the sealing outlet position, the outlet orifice outputs a gas and stores the gas in the metering chamber. At the metering outlet position, the blocking portion seals the outlet orifice through an airtight ring, and outputs the gas stored in the metering chamber through the inlet orifice and the discharging channel.

A device for monitoring the mass of a fluid remaining in a tank as the fluid periodically or continuously leaves the tank includes a housing comprising an inlet adapted to be attached to an outlet of the tank and to receive fluid from the tank. A flow meter measures a plurality of flow rate measurements of the fluid as it leaves the tank. At least one processor is configured to determine a mass of the fluid that has left the tank during at least one measurement period, determine a mass of the fluid remaining in the tank based at least partially on an initial mass of the fluid in the tank and the determined mass of the fluid that has left the tank, and generate, based on the mass of the fluid remaining, an indication.

A capillary metering device for a powder product has a vibration body with a capillary formed within the vibration body for receiving and conveying the powder product. The vibration body is formed of at least two adjoining body parts, wherein the capillary is formed as a channel with at least one open side in the demounted state in at least one of the body parts. The open side of the channel in the mounted state is closed off by the adjoining body part. The vibration body is caused to vibrate with such an amplitude and frequency that a powder flow of the powder product passes through the capillary formed in the vibration body into a target container and that upon reaching a target quantity of the powder product in the target container the powder flow to the target container is interrupted.

An activity and volume sensing beverage container cap system for a beverage container including a cap that couples with the beverage container, a processor, a timer and at least one activity level sensor, such as an inclinometer, coupled with the processor. The activity level sensor detects container orientation. When the container is tilted, the timer measures an amount of time in an orientation. Based on the current and previous orientation and the amount of time the container is in different orientations, the processor determines an amount of time of activity of the user, and a level of activity of the user, such as number of steps or moves per time. The inclinometer is also used to determine the amount of volume dispensed from the container when tilted over a threshold indicative of drinking. Thus one inclinometer may be utilized as both to determine activity level and volume of fluid dispensed.
