A simple, effective, lightweight, durable, combination tool having removably attachable interchangeable implements, which are interchangeable one with the other. The combination tool has locking means, which releasably locks the removably attachable interchangeable implements into a handle. The handle can have a light for illuminating an area or work surface, and the food being cooked and/or barbecued. The handle can have a timer capable of being set to at least one time duration, and audibly alerting a user at the end of a selected one of such time durations, as to how long the food has been cooked or barbecued.

The storage medium of claim 6, wherein if said YIQ matrix comprised N-bit values per sensor, execution of said computer program logically dissects said matrix into three matrices, each having (N/3)-bit values per sensor. or valve automatically regulating the water flow therethrough to have a relatively constant flow rate despite variations in the water inlet pressure. 8. The apparatus according to claim 7, wherein said regulator valve comprises a membrane deformable in a flow control passageway in response to water flow through said passageway to maintain a relatively constant flow rate therethrough despite variations in the water inlet pressure. 9. The apparatus according to claim 8, wherein said regulator valve includes a stem having a head of convex configuration facing said membrane but normally spaced therefrom to define said flow control passageway; the convex configuration of said stem head producing, with said membrane, different cross-sectional areas and thereby different flow rates in said control passageway, creating differential pressures acting on said membrane tending to deform the membrane such as to maintain a relatively constant flow rate through the flow control passageway despite variations in water inlet pressure. 10. The apparatus according to claim 9, wherein said stem head is presettable with respect to said membrane to preset the flow rate. 11. The apparatus according to claim 10, wherein said stem head is threadedly received on said stem such that rotation of the stem in one direction moves the stem head towards the membrane, and rotation of the stem in the opposite direction moves the stem head away from the membrane. 12. The apparatus according to claim 1, wherein said pressure-responsive device senses the pressure at the inlet of its housing to control the energization of the electrical heater. 13. The apparatus according to claim 1, wherein said pressure-responsive device senses the flow rate to or through the electrical heater to control the energization of said electrical heater in response to the sensed flow rate. 14. The apparatus according to claim 13, wherein said pressure-responsive device senses the flow rate to or through the electrical heater by sensing the differential pressure at two locations in the flow path, one downstream of the other. 15. The apparatus according to claim 14, wherein the two locations in said flow path have different cross-sectional areas. 16. The apparatus according to claim 14, wherein said pressure-responsive device includes a displaceable member which is displaceable according to said sensed differential pressure and operates said electrical control device which controls said electrical heater. 17. The apparatus according to claim 13, wherein said electrical control device includes a plurality of electrical switches controlled by said displaceable member of the pressure-responsive device, and said displaceable member of the pressure-responsive device sequentially actuates the electrical switches according to the magnitude of displacement of said latter displaceable member to control the magnitude of the electrical heat produced by the electrical heater according to the water flow rate. 18. The apparatus according to claim 17, wherein said displaceable member of the pressure-responsive device includes a spring-urged membrane, and a stem coupled to said membrane and sequentially engageable with said switches to control the magnitude of the electrical heat according to the water flow rate. 19.
