Abstract: A method of sensing magnitude of lumen depreciation not only of a lamp of a lighting fixture, but other factors, by sensing a relative light level external of the lighting fixture to derive not only lamp lumen depreciation but total lumen depreciation from the fixture. An apparatus of monitoring light level of one or more lighting fixtures comprises a sensor positioned external of the lighting fixture(s), a comparator adapted to compare a measured actual lumen output signal from the sensor to a pre-set reference or threshold lumen output value. An error signal is generated by the comparator if the comparison indicates actual lumen output to have dropped below the reference or threshold lumen output. An alarm or communication can be actuated by the error signal to instruct corrective action to ensure relatively constant light levels to be maintained for the lighting system over time, thus providing ongoing assurance to the end user of proper system operation.

Abstract: Apparatus, methods, and systems for providing comprehensive control and monitoring of an electrical system are presented. The envisioned invention according to at least one aspect provides for control and monitoring functions that include main circuit level functions and sub-circuit level functions. The control and monitoring function further provides for communication with a remote central control center to send commands to and receive data from the main circuit control and/or sub-circuit(s). Information from the monitoring function may be used to alter the operation of the system, aid in diagnostic response, and ultimately, improve the safety and reliability of the electrical system.

Abstract: A disposable combination razor and shaving cream dispenser having an aerosol actuated push button shaving cream dispenser and a non-removable cap having a razor blade at the upper end and a pushbutton adapted to engage the push button of the dispenser. In this manner, the dispenser body may be used as a handle when shaving and the cream may be dispensed without removing the cap from the dispenser as needed to be applied by the hand into which the cream is dispensed.
