Color measuring systems and methods are disclosed. Perimeter receiver fiber optics are spaced apart from a central source fiber optic and receive light reflected from the surface of the object being measured. Light from the perimeter fiber optics pass to a variety of filters. The system utilizes the perimeter receiver fiber optics to determine information regarding the height and angle of the probe with respect to the object being measured. Under processor control, the color measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence and/or surface texture data also may be obtained. Audio feedback may be provided to guide operator use of the system. The probe may have a removable or shielded tip for contamination prevention.

Improved contact devices and methods for producing contact devices and using such contact devices to produce electronic devices are disclosed. A contact device having a plurality of nominally coplanar first contact elements makes electrical contact with corresponding nominally coplanar second contact elements of an electronic device such an integrated circuit or liquid crystal or other display when the contact device and the electronic device are positioned so that the plane of the first contact elements is substantially parallel to the plane of the second contact elements and relative displacement of the devices is effected in a direction substantially perpendicular to the plane of the first contact elements and the plane of the second contact elements. The contact device preferably consists of a stiff substrate having a major portion with fingers projecting therefrom in cantilever fashion, each finger having a proximal end at which it is connected to the major portion of the substrate and an opposite distal end and there being one or two contact elements on the distal end of each finger.

Optical characteristic measuring systems and methods such as for determining the color or other optical characteristics of teeth are disclosed. Perimeter receiver fiber optics preferably are spaced apart from a source fiber optic and receive light from the surface of the object/tooth being measured. Light from the perimeter fiber optics pass to a variety of filters. The system utilizes the perimeter receiver fiber optics to determine information regarding the height and angle of the probe with respect to the object/tooth being measured. Under processor control, the optical characteristics measurement may be made at a predetermined height and angle. Various color spectral photometer arrangements are disclosed. Translucency, fluorescence, gloss and/or surface texture data also may be obtained. Such methods and implements may be desirably utilized for purposes of detecting and preventing counterfeiting.

A picture frame and accompanying audio message circuit is provided such that one or more desired audio messages stored in the audio message circuit associated with one or more display pictures can be played upon the touching of the pictures or the frame, or in response to a voice recognition device sensing an audio command associated with the particular audio message and/or pictures. When audio message playback is desired, a switch on the frame or under a protective cover for the picture is activated by touching, or a position sensitive device may be used to sense whether a particular position on the picture has been touched. Digital or analog information representing the desired audio message is retrieved from a memory device, which is subsequently transmitted to a speaker which produces the desired audio message perceptible to a human. In other embodiments, multiple picture and multiple messages are provided such that the user can touch a particular picture, or the switch associated with that picture, and an audio message corresponding to the picture is then played through the speaker. In still other embodiments, a system is provided with a plurality of pictures mounted in the perimeter faces of a cube or other geometrical shape, each picture having associated with it a switch for activating a message or plurality of messages.
