Abstract
An out of product indicator is provided. The out of product indicator includes a power generator, a sensor and an alarm. The power generator is configured to generate power based on an interaction with at least one aspect of the device it is coupled thereto. The sensor is configured to determine when a product is low. The alarm is coupled to receive power generated by the power generator. Moreover the alarm is activated based on an output of the sensor.
Claims21
An out of product indicator comprising:
- a dispenser configured to selectively hold a solid product that wears away during use, the dispenser including a housing;
- a power generator configured to generate power based on an interaction with at least one aspect of a device it is coupled thereto;
- a sensor configured and arranged to generate an output signal when the product is low and a door of the device allowing access to the out of product indicator is opened;
- and
- an alarm coupled to receive power generated by the power generator, the alarm being activated based on a generated output signal of the sensor.

An out of product sensor comprising:
- a dispenser configured to selectively hold a solid product that wears away during use, the dispenser including a housing;
- a sensor received in the housing, the sensor configured to monitor the solid product and produce a signal when the product is low;
- an alarm received in the housing, the alarm configured to indicate when the sensor has sensed a low product;
- and
- a power generator received in the housing, the power generator configured to power the sensor and the alarm, the power generator configured to generate power based on the movement of a device the dispenser is mounted thereto.

An out of product indicator comprising:
- a dispenser having a first surface configured to selectively hold a solid product that wears away during use and a second surface configured to be mounted to a device that moves, the dispenser further including a housing;
- a sensor received in the housing, the sensor configured to monitor the product and produce a signal when the product is low and a door allowing access to the device is opened;
- an alarm received in the housing, the alarm configured to indicate when the sensor has sensed a low product;
- a power storage device coupled to provide power to the sensor and the alarm;
- and
- a power generator received in the housing, the power generator configured to charge the power storage device, the power generator configured to generate power based on the movement of the device the dispenser is mounted thereto.
