Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] The present application is a Continuation Application of U.S. patent application Ser. No. 11/001,129 filed Dec. 2, 2004, which is a Divisional Application of U.S. patent application Ser. No. 09/917,822 filed on Jul. 31, 2001. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention generally relates to a seating platform, or chair, and more particularly to a freely movable chair which includes electronic devices for sensing, communications, and a wireless power supply for providing energy to the chair. [0004] 2. Description of the Related Art [0005] Chairs and other similar seating platforms are pervasive. There are perhaps ten chairs for each individual in North America. Chairs are an ideal device for sensing information about occupants of the chair, in an office for example, and for sending and receiving information to computing systems. Typically, chairs in such an environment are free to move. Input/output systems that depend on wires are ruled out. Devices built into chairs must have a source of energy. Again, wired energy sources are ruled out. [0006] It has been recognized that chairs may serve as platforms for electronics. See, for example, U.S. Pat. No. 6,220,382 "Powered wheelchair with separating frame" issued to Karamer, Jr. et al., U.S. Pat. No. 4,180,062 "Portable childbirth chair with electronic monitoring apparatus" issued to Alberti et al., U.S. Pat. No. 5,961,561 "Method and apparatus for remote maintenance, troubleshooting, and repair of a motorized wheelchair" issued to Wakefield, II, and U.S. Pat. No. 5,630,566 "Portable ergonomic work station" issued to Case, each incorporated herein by reference. [0007] It has been also recognized that chairs equipped with electronic devices require a source of electrical energy. However, the solutions provided (e.g., to equip the chair with heavy and space consuming batteries, or to attach wired sources of energy to the chair) pose their own drawbacks. Batteries must be recharged by plugging them into power sources or they must be replaced periodically. Further, connecting the chair to a source of electrical power limits its mobility. By the same token, replacing batteries is inconvenient and expensive. [0008] It has also been recognized that sensors may be used to monitor the occupation of a chair. See, for example, U.S. Pat. No. 6,204,767 "Chair monitor" issued to Sparks, incorporated herein by reference. [0009] However, it has not been recognized that wireless systems may be used to provide communications for the chair to a computing system in order to activate effectors to change the environment in which the chair is found. Further, it has not been recognized that a wireless connection between the chair and a computing network may be used to inform others of the state of occupation of the chair. SUMMARY OF THE INVENTION [0010] In view of the foregoing and other problems, drawbacks, and disadvantages of the conventional methods and structures, an object of the present invention is to provide a seating platform with an electronic mechanism for sensing the occupation of the chair, transmitting an indication of the occupation wirelessly to a computing system, and further providing a unit for the computing system to actuate effectors to change the environment of the chair. [0011] It is also an object of this invention to provide a connection unit for connecting the electronically equipped chair to a network so that information about the state of the chair and its occupant may be relayed to others at distant locations. [0012] It is also an object of this invention to provide a means for determining that a particular occupant has occupied the chair and whether that occupant is a human or a non-human, (e.g., a dog or a cat). [0013] Further, it is an object of this invention to provide a wireless unit for providing energy to the electronics carried by the chair so as to allow the chair to remain mobile without the need for wired connections. [0014] It is also an object of this invention to eliminate the need for the replacement of batteries that may be used to supply energy to the chair devices. [0015] In a first aspect of the present invention, a system includes a seating platform, at least one sensor for detecting a state of the seating platform connected to a first wireless communications device, the first wireless communications device for conveying information on the state of the seating platform, a second wireless communications device for receiving information from the first wireless communications device, and a computing system. The second wireless communications device is for receiving the information carrying signal and is connected to the computing system. The computing system is for initiating an action based upon the information. [0016] In a second aspect, a system includes a seating platform, electronic devices within the seating platform and requiring energy, and a wireless energy transfer unit for transferring energy to the devices. [0017] In a third aspect, a method of communicating between a seating platform and a remote system, includes sensing a characteristic of an occupant of the seating platform, communicating the characteristic from the seating platform to the remote system, and providing a feedback loop between the seating platform and the remote system. [0018] With the invention, the seating platform senses the occupation of the chair, transmits an indication of the occupation wirelessly to a computing system, and enables the computing system to actuate effectors to change the environment of the chair. Additionally, the electronically-equipped chair can be connected to a network so that information about the state of the chair and its occupant may be relayed to others at distant locations. Moreover, energy is provided to the electronics carried by the chair so as to allow the chair to remain mobile without the need for wired connections. Additionally, the invention eliminates the need for replacement of batteries that may be used to supply energy to the chair devices.
