Abstract: A liquid level monitoring system is configured for a wood-stemmed plant in which the stem is receivable by a reservoir configured to hold a liquid. The system includes a housing attachable to the stem of the plant. The housing may include an aperture for receiving some of the liquid in the reservoir. A circuit board is coupled to or positioned within the housing and includes a microprocessor. A sensor may be located within the housing or attached externally thereto. The sensor is operable to transmit a signal to the processor when the sensor becomes exposed primarily to air instead of the liquid in the reservoir. And, an indicator is in communication with the processor to provide at least one human perceptible signal that correlates with a liquid level in the reservoir.

Abstract: A method and system for opportunity distribution. Respective first and second groups of users are identified. An opportunity is provided to the first group of users. A trigger event is detected. The opportunity is selectively provided to the second group of users based on the detection of the trigger event.
