Examples of calendaring functions may include managing a calendar associated with the portable hub 104, managing calendar events, and/or other calendaring functions. The calendaring functions provided by the calendaring module 158 may be presented to a user via the hub display apparatus 138 and/or the hub user interface 140. Calendaring functions may be manipulated via the hub user interface 140.

(37) The hub power management module 160 may be configured to manage power delivered by the hub power supply 142 to one or more components of the portable hub 104. In some implementations, the hub power management module 160 may temporarily discontinue or reduce power being supplied to one or more components of the portable hub 104 when those component(s) are not currently in use, such as hub communications apparatus 130, the hub identification sensor 132, the hub geo-location sensor 134, the hub motion sensor 136, the hub display apparatus 138, the hub user interface 140, the hub electronic storage 144, the hub processor 146, and/or other components. As such, the hub power management module 160 may extend the lifetime of the hub power supply 142 and/or an individual charge thereof.

(38) The computing platform 106 may be configured to communicatively couple to the portable hub 104 and/or other components of the exercise system 100. The computing platform 106 may be configured to receive, transmit, process, and/or store information related to one or more of physical activity, at least one exercise parameter, force exerted on the force sensing node 102, information stored by the hub electronic storage 144, information and/or signals related to one or more components of the force sensing node 102 and/or the portable hub 104, and/or other information. Processing of such information may include analysis, historical tracking, sharing with one or more individuals other than a user of the portable hub 104, and/or other processing. The computing platform 106 may be physically separate and distinct from the force sensing node 102 and/or the portable hub 104. The computing platform 106 may include one or more processors configured to execute computer program modules that provide the functionalities attributed herein to the computing platform 106. According to some implementations, the computing platform 106 may include one or more of a personal computer, a laptop computer, a tablet computer, a Smart phone, a personal digital assistant (PDA), and/or other computing platforms.

(39) The user accessory 108 may be configured to communicatively couple to the force sensing node 102, the portable hub 104, and/or other components of the exercise system 100. The user accessory 108 may be configured to convey information related to one or more of personal exercise, aspects of a user of the portable hub 104 (e.g., heart rate, temperature, and/or other aspects), force exerted on the force sensing node 102, information associated with the portable hub 104, and/or other information. The user accessory 108 may be physically separate and distinct from the force sensing node 102 and/or the portable hub 104. In some implementations, the user accessory 108 may include one or more of a heart rate monitor, a thermometer, a device that measures aspects of a user of the portable hub 104, a wired headset, a wireless headset, wired headphones, wireless headphones, a device that includes a display, and/or other accessories.

(40) The external resources 110 may include sources of information, hosts and/or providers of interactive content outside of the exercise system 100, external entities participating with the exercise system 100, and/or other resources. In some implementations, some or all of the functionality attributed herein to the external resources 110 may be provided by resources included in the exercise system 100.

(41) FIG. 2 illustrates a method 200 for gathering and quantifying data related to energy expenditure during physical activity, according to one or more implementations of the invention. The operations of the method 200 presented below are intended to be illustrative. In some implementations, the method 200 may be accomplished with one or more additional operations not described, and/or without one or more of the operations discussed. Additionally, the order in which the operations of the method 200 are illustrated in FIG. 2 and described below is not intended to be limiting.

(42) In some implementations, the method 200 may be implemented in one or more processing devices (e.g., a digital processor, an analog processor, a digital circuit designed to process information, an analog circuit designed to process information, a state machine, and/or other mechanisms for electronically processing information). The one or more processing devices may include one or more devices executing some or all of the operations of the method 200 in response to instructions stored electronically on an electronic storage medium. The one or more processing devices may include one or more devices configured through hardware, firmware, and/or software to be specifically designed for execution of one or more of the operations of the method 200.

(43) At an operation 202, a first output signal is generated responsive to force being exerted on at least one force sensing node (e.g., the force sensing node 102) during physical activity. In some implementations, the first output signal may be generated by the force sensor 112 of the force sensing node 102.

(44) At an operation 204, the first output signal is transmitted from the at least one force sensing node (e.g., the force sensing node 102) to a portable hub (e.g., the portable hub 104). The portable hub may be physically separate and distinct from the at least one force sensing node. In some implementations, the node communications apparatus 114 may received the first output signal from the force sensor 112 and transmit the first output signal to the portable hub 104 or a component thereof (e.g., the hub communications apparatus 130).

(45) At an operation 206, one or more exercise parameters are determined at the portable hub (e.g., the portable hub 104) based on the first output signal. In some implementations, the hub processor 146 may execute the exercise analysis module 152 to determine the one or more exercise parameters.

(46) At an operation 208, information related to the one or more exercise parameters is presented at the portable hub (e.g., the portable hub 104). In some implementations, such information may be presented by the hub display apparatus 138 and/or the hub user interface 140. In some implementations, the information related to the one or more exercise parameters may be transmitted to and presented by the computing platform 106 rather than or in addition to being presented at the portable hub 104.

(47) Although the invention has been described in detail for the purpose of illustration based on what is currently considered to be the most practical and preferred implementations, it is to be understood that such detail is solely for that purpose and that the invention is not limited to the disclosed implementations, but, on the contrary, is intended to cover modifications and equivalent arrangements that are within the spirit and scope of the appended claims. For example, it is to be understood that the present invention contemplates that, to the extent possible, one or more features of any implementation can be combined with one or more features of any other implementation.
