An electrical power or electronic data unit includes an outer housing and an inner housing that is insertable into the outer housing. The outer housing has an outer front face panel defining an outer receptacle opening and the inner housing has an inner rear housing portion plus an inner front face portion defining an inner receptacle opening aligned with the outer receptacle opening. A circuit board substrate is positioned inside the inner housing with an electrical contact mounted to the board substrate and aligned with and accessible through the inner and outer receptacle openings. A contact support extends rearwardly from the inner front face portion adjacent the inner receptacle opening, the contact support serving to limit movement of the electrical contact during insertion of a plug or prong into engagement with the electrical contact.

An electrical power distribution system automatically limits the number of substantially similar or identical power cable assemblies that are electrically energizable from a power source. A control unit is connected between the power source and the power cable assemblies, and limits the number of power cable assemblies that can be energized in the system by sensing the voltage in a sensing circuit. An applied voltage in the sensing circuit changes in a predictable manner corresponding to the number of power cable assemblies that are electrically connected in the circuit. Each power cable assembly includes an impedance element that is added to the sensing circuit when the corresponding power cable assembly is coupled to the system, and once the detected voltage is beyond a predetermined threshold value, the control unit will ensure that the power cable assemblies are not energized by the power source.

Time consuming analyzing of the dressing levels on bowling lanes is eliminated through the use of an apparatus that includes a path of travel (48) for a sample strip, a light source (50) on one side of the path (48) and a photosensitive sensor (46) on the other side of the path. A feed roller (60) is journaled adjacent the path and is driven by a stepper motor (58) in predetermined increments. An analog to digital converter (40) is connected to the sensor (36) for receiving analog signals therefrom and converting the same to digital signals. A random access memory (38) is connected to the converter (40) for receiving signals therefrom and for storing data represented by the signals. A central processing unit (34) is provided for operating the motor (58), the sensor (46) and the random access memory (38). Also included is a program storage (38) for storing control algorithms for the central processing unit (34) along with a port (66) connected to the central processing unit (34) for receipt of exteriorally generated commands and for outputting stored or otherwise acquired data.
