Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 400: Typewriting Machines

This is the generic class for an apparatus wherein a user of the apparatus causes an intelligible character* to be imprinted on a record-medium* by a type-member* that is impressed on the record-medium, said type-member being selected from a plurality of different type-members, and the selected type-members being impressed serially to form a sequence of characters that record intelligible information.

Subclass 485: Key-board having multiple-character, multiple-movement keys
Subclass 493: Including character-bearing disc on key cap

Class 178: Telegraphy

Means for transmitting to a distance messages, unlimited with respect to the extent of information they are adapted to convey, and the transmission and facsimile reproduction of written, printed, or otherwise produced characters, marks, pictures, etc., unlimited with respect to form or outline, by the utilization of conductive or inductive electrical current impulses or reversals, the elements of the messages being selected or composed at will, according to a prearranged code, or the transmitter being actuated or controlled by a previously designed pattern.

Subclass 17C: Keyboard

Class 200: Electricity: Circuit Makers And Breakers

Combinations of circuit makers and breakers with electrical plugs, sockets, or other connectors are in this class. This class includes devices known as "controllers", "circuit-closers", "switches", "circuit-breakers", "interrupters", "distributers", "thermal-cut-offs", "fuses", and "electrical thermostats".

Subclass 345: Cap/stem and stem/housing details

Class 235: Registers

Machines employed for ascertaining the number of movements of various devices or machines; also, indicating devices where the purpose is to disclose the numerical extent or quantity of movement of a machine and where the device is separate and independent of the machine whose movements are to be noted; also organized machines, such as, cash-registers, fare-registers, voting machines and calculators having registering or counting devices as essential or important elements and having in addition certain other features necessary to make up the complete machines for the purposes desired.

Subclass 145R: KEYBOARDS

Class 341: Coded Data Generation Or Conversion

1) originating or emitting a coded set of discrete signals or 2) translating one code into another code wherein the information signal content remains the same but the formats may differ. For classification herein, at least one of the codes must be a set of pulses or digits and electrical in nature.

Subclass 22: Including keyboard or keypad

Class 725: Interactive Video Distribution Systems

This class contains interactive video distribution processes, systems, and elements thereof, which are characterized by point-to-multipoint system configurations, and which are used for the unidirectional distribution or delivery of motion video data resulting from interactions between systems operators (access or service providers) or users (subscribers) and systems elements. These systems include dedicated communications systems, such as television distribution systems, which primarily distribute or deliver motion video data in the manner indicated, but which may, in addition, provide a framework for further, diverse data communications or services in either unidirectional or bidirectional form. Typically, system operators interface with transmitter-side elements or users interface with receiver-side elements in order to facilitate, through interaction with such elements, the dynamic control of data processing or data flow at various points in the systems. This interaction is typically occasional or intermittent in nature.

Subclass 13: Manual entry (e.g., using keypad or by written response)

Class 984: Musical Instruments

Subclass 61: Keyboards; Keys {G10C 3/12}
