Remote generation and distribution of command programs for programmable devices description/claims

This application is a continuation of U.S. patent application Ser. No. 10/966,848, filed Jan. 28, 2005, which is a continuation of U.S. patent application Ser. No. 09/780,316 filed Feb. 9, 2001, which is a continuation-in-part of U.S. patent application Ser. No. 08/944,529 filed Oct. 7, 1997, each of which are incorporated by reference in their entirety. This application also claims the benefit of Provisional Application Ser. No. 60/181,577, filed Feb. 10, 2000, which is incorporated by reference in its entirety.

The present invention relates to control systems for programmable devices and, more particularly, to the generation and distribution of control commands that control the operation of programmable devices.

A wide variety of devices contain a combination of software and hardware that control the operation of the device. These devices will be referred to herein as programmable devices. Programmable devices include a wide variety of items such as toys, industrial motion control systems, exercise equipment, medical devices, household appliances, HVAC systems, and the like.

A common characteristic of such programmable devices is that they are programmed to perform a limited number of predetermined tasks. For example, a toy may be programmed to speak, move, or react to external stimulation in a predetermined manner. An industrial motion control system is programmed to assemble parts in a precise, repetitive manner. A household appliance may be programmed to perform one or more cooking or cleaning tasks. An HVAC system will be programmed to control a heating element and heat distribution systems to obtain a desired air temperature.

Some programmable devices contain means for allowing the end user to control the functionality of the system to a limited degree. In the context of a toy, the end user may operate a switch or joystick to select a manner of movement. An HVAC system will normally allow the end user to set the desired temperature. In most cases, however, the input of the end user is limited to changing variables or selecting from among a plurality of stand-alone programs.

Programmable devices thus take many forms but have certain common characteristics. A programmable device includes some form of memory for storing control commands that define a predetermined command program. The command program may accept input from the user or contain discrete sub-programs from which the end user may select, but the end user may not modify the command program.

A programmable device further comprises a processor capable of executing the command program and generating control signals. To reduce manufacturing costs, the processor is normally an inexpensive dedicated processor with relatively limited capabilities and resources.

A programmable device will also comprise control hardware that performs a desired task as defined by the control signals. The control hardware can be as simple as an LED or speaker that generates light or sound or as complicated as a multi-axis industrial motion control device that performs a complex welding procedure.

The relevance of the present invention is particularly significant given the varying degrees of technical skill possessed by the various patient end users involved in the design, manufacturing, and use of a typical programmable device. The user of a programmable device must be assumed to have little or no capability to create the command programs necessary to operate a programmable device. Certainly a typical child using a toy will not have the skills necessary to create command program for that toy. Even a highly trained technician operating an industrial motion control system typically will likely not have the skill to program the system to perform a desired task.

Accordingly, in this application the term “end user” will refer to a person who uses a programmable device but cannot be assumed to have the expertise to create a command program for that programmable device.

In contrast, the term “programmer” will be used herein to refer to a person having the expertise to create a command program for a particular programmable device. The skill level and background of the programmer will vary depending upon the specific programmable device; the term programmer is thus not intended to define a particular level of expertise, but is instead defined in relation to the specific programmable device.

With some programmable devices, the programmer has no direct contact with the end user. For example, a programmer of a toy or household appliance will typically not have direct contact with the end user. A programmer of an HVAC system or industrial motion control system may, on the other hand, have contact with the end user.

Without direct contact with the end user, the programmer must anticipate what task the end user will desire of the programmable device. Even with direct contact, the programmer may not fully comprehend the desired task, or the desired task may change after the command program has been created. In either case, obtaining the services of the programmer to modify the command program is likely to be difficult and expensive, if not impossible.

In general, while the end user may not be able to create a command program, the end user will be able to define the desired task. A technician operating an industrial motion control system will likely be able to observe that a change in the operation of the system will increase product yield or speed up the manufacturing process. Even a child might be able to determine that a doll that walks should also be able to jump.

The term “end user” may include any other person involved with a programmable device without the technical expertise to qualify as a programmer of that device. For example, a medical device may be used by a patient and controlled by a caregiver, neither of which would have the expertise to be considered a programmer; both the patient and the caregiver would be considered end users in the present application.

The purpose of the present invention is to facilitate the generation and distribution of command programs for programmable devices. In particular, the present invention is designed to allow an end user of a particular programmable device to define a desired task, interact with a remote computer over a communications network to generate a command program, and then download the command program into the programmable device over the communications network.

The present invention may be embodied as a system for controlling a motion device. A motion control system comprises a motion control device, and a first user is associated with the motion control system. An output system is arranged to generate motion signals that may be perceived by the first user. A motion server system comprises a plurality of motion scripts associated with messages to be transmitted to the first user and a motion program web page. A processing system comprises a browser program compatible with the motion program web page. A communications system transfers data between the various systems. A second user controls the server system to form a motion message corresponding to a desired motion signal based on the at least one motion script stored by the server system. The motion control system causes the output system to generate the desired motion signal based on the motion message.
