Abstract
Abstract A floor mat includes a housing for containing a power supply, speech module and speaker. A grid-like switching mechanism is closed upon a person stepping on the mat so as to provide an energizing current flow to the speech module. The speech module includes circuitry for recording and playing back a selected message. A slidable or releasable panel in the housing allows for selectable user access to the speech module. The housing precludes weather deterioration of the elements therein and cooperates with the switching mechanism so as to provide a user-selectable message to a person stepping on the mat. The mat/housing configuration allows alternative switching mechanisms to be used in connection with replaceable speech modules.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
113 words
A floor mat comprising: a mat for placement on a support surface; a speech module assembly including electrical circuitry for recording and playback of a selected message; a power source for said circuitry; a housing on said mat for said speech module; a speaker in said housing and in communication with said speech module; a slidable panel in said housing, said panel slidable in a first direction for allowing a user access to said speech module and a second direction for closing said housing; switch means in said mat for causing a current flow through said speech module upon an exertion of pressure on said mat, whereupon to play back the selected message.
Claim 2
Dependent Claim
113 words
A floor mat comprising: a mat for placement on a support surface; a speech module assembly including electrical circuitry for recording and playback of a selected message; a power source for said circuitry; a housing on said mat for said speech module; a speaker in said housing and in communication with said speech module; a slidable panel in said housing, said panel slidable in a first direction for allowing a user access to said speech module and a second direction for closing said housing; switch means in said mat for causing a current flow through said speech module upon an exertion of pressure on said mat, whereupon to play back the selected message.
Claim 3
Dependent Claim
123 words
The device as claimed in claim 1 wherein said switch means comprises: a generally rectangular panel having first and second portions; a plurality of elongated parallel strips of a conductive material in said first panel; a plurality of elongated parallel strips of a conductive material in said second panel, said first panel strips normal to said second panel strips; a third panel intermediate said first and second panels; a plurality of apertures in said third panel, whereupon said apertures allowing for at least one of said first panel strips to contact an underlying second panel strip upon a pressure being exerted on said mat, said contact allowing for a current flow through said switch; means for connecting said switch with said speech module.
Claim 4
Dependent Claim
16 words
The device as claimed in claim 2 wherein said switch means is embedded in said mat.
Claim 5
Dependent Claim
60 words
The device as claimed in claim 1 wherein said switch means comprises: a wire loop; means for connecting said loop with a power supply of said speech module, said loop presenting a capacitance-type switch whereupon a exertion of pressure on said map causes a voltage change in said switch, said voltage change causing a current flow through said speech module.
Claim 6
Dependent Claim
16 words
The device as claimed in claim 4 wherein said loop follows a perimeter of said mat.
Claim 7
Dependent Claim
15 words
The device as claimed in claim 4 wherein said loop is embedded in said mat.
Claim 8
Dependent Claim
26 words
The device as claimed in claim 1 further comprising: a jack in communication with said speaker for communicating the speech module with an external audio transducer.
Claim 9
Dependent Claim
78 words
The device as claimed in claim 1 wherein said housing comprises: a compartment having at least first and second opposed side walls for encompassing said module; a rail at a top of each side wall to present a track, said panel having structure for engaging said track for slidable movement in a first direction to open said compartment and expose said speech module therein and a second opposed direction to close said compartment and cover said speech module.
Claim 10
Dependent Claim
86 words
In a floor mat having a normally open pressure-responsive switch for energizing an electrical device upon pressure being exerted on said mat, the improvement comprising: a housing on said mat; a speech module comprising said device and having an associated power supply and speaker in said housing; a slidable panel in said housing, said panel slidable in a first direction to allow a user access to said housing and second direction for closing said housing, whereupon said panel allows said user access to said speech module.
Claim 11
Dependent Claim
86 words
In a floor mat having a normally open pressure-responsive switch for energizing an electrical device upon pressure being exerted on said mat, the improvement comprising: a housing on said mat; a speech module comprising said device and having an associated power supply and speaker in said housing; a slidable panel in said housing, said panel slidable in a first direction to allow a user access to said housing and second direction for closing said housing, whereupon said panel allows said user access to said speech module.
Claim 12
Dependent Claim
68 words
In a floor mat having a normally open pressure-responsive switch for energizing an electrical device upon pressure being exerted on said mat, the improvement comprising: a housing on said mat; a speech module comprising said device and having an associated power supply and speaker in said housing; a releasable panel in said housing, said panel allowing for a user access to said housing and said speech module therein.
Claim 13
Dependent Claim
68 words
In a floor mat having a normally open pressure-responsive switch for energizing an electrical device upon pressure being exerted on said mat, the improvement comprising: a housing on said mat; a speech module comprising said device and having an associated power supply and speaker in said housing; a releasable panel in said housing, said panel allowing for a user access to said housing and said speech module therein.
Claim 14
Dependent Claim
18 words
The device as claimed in claim 10 wherein said releasable panel is on the bottom of said housing.
Claim 15
Dependent Claim
86 words
