A toothbrush including a head, a tuft of bristles positioned at the head, a piezoelectric film disposed within the head in such a way that a force applied to the tuft of bristles generates voltage in the piezoelectric film, and an indicator for indicating that a predetermined level of voltage is being generated in the piezoelectric film. Preferably the tuft of bristles is able to 'float' within the head of the toothbrush. The indicator is constructed to provide a signal that is perceivable by a user of the toothbrush (e.g., a visible signal or an audible signal).

Pressure-sensing toothbrush

An emission system includes emitter support structure with a plurality of flow passages therethrough and an array of emitter members that are in adjacent relation to the flow passages and that project outwardly from a surface of the support structure with the free ends of the emitter members spaced from one another and from the support structure (in the nature of cut pile or tufted rug structure in particular embodiments), and thermal excitation structure for flowing fuel through the passages and establishing a combustion condition at the surface to heat the emitter members to thermally emissive temperature.

An incandescent gas mantle assembly includes a metal coupling member and a mantle supporting sleeve member of thermally resistant material that has a skirt portion to which a metal oxide mantle sock is secured in depending relation. The metal coupling member has a body portion of disc configuration with an outer periphery and an inner periphery, a plurality of inwardly extending first coupling portions integral with and spaced about the body portion for attachment to a cooperating burner head, and a plurality of second coupling portions integral with and spaced about the body portion, the second coupling portions being in coupling engagement with recess structure of the mantle supporting sleeve member.
