Abstract: An apparatus that is capable of detecting the presence of a plug comprising: a plurality of receptacles configured to receive a plurality of prongs from a plug, wherein the plurality of receptacles includes a first receptacle and a second receptacle; a controller configured to detect whether a first prong of the plurality of prongs is present in the first receptacle; and a switch configured to provide power to the second receptacle. The switch provides power to the second receptacle when the controller detects that the first prong of the plurality of prongs is present in the first receptacle and the switch does not provide power to the second receptacle when the controller does not detect that the first prong is present in the first receptacle.

Abstract: An invention is provided for encouraging routine testing for TDS levels in a liquid. The invention includes a conductivity sensor capable of sensing a conductivity level of a liquid, and a processor in electrical communication with the conductivity sensor. The processor has logic that calculates a TDS level for the liquid based on the conductivity level of the liquid. The calculated TDS level for the liquid is then displayed on a display in electrical communication with the processor. Also included is a speaker, which is electrical communication with the processor. To provide automatic reminders to the user, an integrated timing mechanism is included that is in communication with the processor. When a predetermined period of time has elapsed, such as the period of time between periodic TDS level testing, the integrated timing mechanism sends a signal to the processor to provide an alert to the user to test the TDS level.

Abstract: An invention is provided for encouraging routine testing for TDS levels in a liquid. The invention includes determining a TDS level of the liquid utilizing an apparatus capable of determining a TDS level based on the conductivity of the liquid. Next, corrective action can be performed to reduce the TDS level when the TDS level is beyond a predetermined level. To facilitate a continual visual reminder for future TDS level testing, the apparatus is removably attached to a surface viewable when in proximity of a device utilized to access the liquid utilizing an integrated attachment mechanism.
