Abstract: A method includes initiating a session at a first device having a session identifier. The session being one-to many. The method further includes joining the session with a third device and a second device using a session identifier, generating a physical condition signal at a physical condition sensor, converting the physical condition signal to a first signal, communicating the first signal to the second device and third device through a network, and generating an indicator at the second device or the third device corresponding to the first signal.

Abstract: A golf swing training apparatus includes a handle assembly, a flexible neck and a head assembly flexibly coupled to the handle assembly with the flexible neck. The head assembly has a frame assembly and a weight assembly flexibly coupled within the frame assembly with a plurality of weight supports with specific levels of elasticity.

Abstract: A system and method for communicating content using remnant capacity includes an intermediate device having a content storage, a user device in communication with the intermediate device and a communication system provider communicating content to the intermediate device. The intermediate device stores the content the content storage. The user device requests content from the content storage. The intermediate device communicates content from the content storage to the user device in real time in response to requesting.

Abstract: A communications system includes a first wireless communications system configured to provide wireless communications over a first frequency band, and a second wireless communications system configured to provide wireless communications using at least a portion of the first frequency band. The system includes an inter-system communications link between the first wireless communications system and the second wireless communications system. The inter-system communications link is used to coordinate the use of the first frequency band. The system further includes an interference reducer configured to reduce interference between the first wireless communications system and the second wireless communications system. Related methods are also disclosed.
