Definitions
- This invention relates to an apparatus, method, and system for communicating data. More particularly, this invention relates to a footwear-implantable device which may be powered by harvesting energy from the use of footwear by a walking or running pedestrian and may be stored and/or converted to communication signals to transmit information.
- a footwear-implantable device which may be powered by harvesting energy from the use of footwear by a walking or running pedestrian and may be stored and/or converted to communication signals to transmit information.
- electronics have become smaller and more durable, there has been a progression towards incorporating electrical devices into clothing or other accessories capable of being worn on the human body. Some examples of such applications include footwear containing light-emitting diodes, ski and snowboard boot heating devices, jackets with a control panel for cell phone or MP3 players and clothing containing continuous heart- rate monitoring devices.
- the current technology requires that the electronics have a source of energy to operate.
- This energy source is typically a battery, which can be embedded within the electronics and configured for a single use, configured to be replaceable, or configured to be rechargeable.
- a battery which can be embedded within the electronics and configured for a single use, configured to be replaceable, or configured to be rechargeable.
- Each of these current options has shortcomings, as the embedded battery may render the associated electronics less useful once the battery is discharged or damaged, replaceable batteries require additional space and material to hold the battery, and an externally rechargeable battery requires additional material for a connecting plug and a battery charger.
- Each of these options is not ideal, as consumers, particularly athletes, tend to demand equipment and clothing that is lighter and without additional power cords.
- Pedestrians impart energy onto, for example, footwear each time he or she walks, jogs, or runs, which presents an opportunity to harness a small portion of the energy expended by incorporating an energy-harvesting device within, for example, footwear.
- the harvested energy may be used instantaneously or stored in a component such as a battery and used at defined time intervals or when requested by a remote device.
- an energy-harvester such as a piezoelectric mechanism
- the present invention may include, for example, a unique arrangement of a microcontroller, a power management unit, a signal transmitter, a signal receiver, a thin-film battery and an energy-harvester.
- the energy-harvester may be a piezoelectric sensor that converts motion/vibration energy into electric energy, wherein the converted energy may be used to recharge a battery, thereby providing power to a signal receiver/transmitter.
- the piezoelectric mechanism may perform a dual function as a converter of motion energy to electrical energy and also a pedometer.
- Certain embodiments of the present invention are also included in a system having a transmitter for transmitting a message to an external receiver.
- the system may also have sensors that may be monitored by a microcontroller. Certain signals from the sensor may be processed by the microcontroller and the processed information may be transmitted to a receiver that is located on the pedestrian or remotely, such as along the path of the pedestrian's course or on a satellite.
- the portable receiving device may process the information received and then send a signal back to the footwear, directing it to take an appropriate action. For example, if the number of steps taken reaches a specified number, the portable device may send a signal to the footwear to become softer or stiffer.
- the footwear may transmit a signal to a GPS satellite to determine the geographical location of the footwear-pedestrian.
- the GPS satellite may send a signal back to the footwear to direct the footwear-pedestrian to take a different route or make any other announcement.
- FIG. 1 is a diagram of an embodiment of the present invention showing a pedestrian using the device.
- Figure 2 is a detailed view of an article of footwear having the device embedded according to and embodiment of the present invention.
- Figure 3 is a diagram of an embodiment of the present invention showing the subcomponents of the device.
- Figure 4 is a diagram of an embodiment of the present invention showing the step-by-step construction of the device.
- a reference to “a step” or “a means” is a reference to one or more steps or means and may include sub-steps or subservient means. All conjunctions used are to be understood in the most inclusive sense possible. Thus, the word “or” should be understood as having the definition of a logical “or” rather than that of a logical “exclusive or” unless the context clearly necessitates otherwise. Structures described herein are to be understood also to refer to functional equivalents of such structures. Language that may be construed to express approximation should be so understood unless the context clearly dictates otherwise.
