Abstract: A measuring device for providing a portable and easy-to-use electronic measuring device. The measuring device generally includes a housing which includes a locking member, a reel member, a sensing assembly and control unit. A length of string is wound around the reel member, which is secured within the housing in a manner which allows the string to be retracted around the reel member absent outside force. As the string is dispensed through a string opening on the housing, a sensor wheel having a plurality of counting indicia will be rotated underneath one or more sensing members, which act to calculate the distance of string which has been dispensed. This data is communicated to a control unit, which causes the relevant information to be shown on a display on the housing. The locking member may be utilized to stop the string from being dispensed after the requisite length has been dispensed.

Abstract: A marking and leveling device for assisting in the hanging of an object such as a portrait on a structure such as a wall. The marking and leveling device generally includes a central portion having a first extension extending in a first direction from a first end of the central portion and a second extension extending in a second, opposite direction from a second end of the central portion. Each of the extension members include a guide member slidably positioned thereon. Each guide member includes a support member for supporting a fastener or marking device used. A leveling assembly which includes a liquid-based leveling member is rotatably secured within the central portion of the present invention. By utilizing the leveling assembly and guide members, an operator of the present invention may accurately level and mark/fasten a structure using a single device.
