Disclosed herein are a ball marker for golf information processing and a golf information processing method using the same, wherein, when a user who plays a round of golf manages, processes, and receives golf information pertaining to a round of golf using a mobile terminal, such as a smartphone, a tablet PC, or a smart watch, it is possible for the user to easily and conveniently manage and process the golf information through the mobile terminal without directly controlling the mobile terminal or inputting necessary information into the mobile terminal, i.e. without a hassle, thereby improving user convenience.

The invention relates to a sensor apparatus, comprising: a sensor unit, a wireless communication unit configured to directly or indirectly transmit and receive data to and from an external source, and means for receiving identification information from a sports item while being attached to the sports item, wherein the apparatus is initiate identification of the sports item in response to a trigger from an identification activation element in the sports item.

A system, device, and methods include or utilize a microphone, a processor, and a user interface. The microphone senses sound and in response outputs a sound signal indicative of the sound. The processor is coupled to the microphone to receive the sound signal, configured to analyze the sound signal to identify in the sound signal an impact of a golf club with a golf ball during a swing of the golf club and determine a characteristic of the swing of the golf club based on a portion of the sound signal corresponding to sound sensed, at least in part, before the impact. The user interface is coupled to the processor and configured to display information related to the characteristic of the swing as determined by the processor.

Embodiments are disclosed for a wearable computer with fitness machine connectivity for improved activity monitoring. In an embodiment, a method comprises: establishing, by a processor of a wireless device, a wireless communication connection with a fitness machine; obtaining, by the processor, machine data from the fitness machine; determining, by the processor, a workout session according to the machine data; initiating the workout session on the wireless device; during the workout session: obtaining, from a sensor of the computing device, physiological data of a user of the fitness machine; determining, by the processor, fitness data for the user based on the physiological data, the machine data and at least one user characteristic; and sending, by the processor, the fitness data to the fitness machine.

Systems and methods herein provide for safe and efficient strengthening of core muscles of a user. An example device can include various components for securing a user in a safe position, tilting the body of the user, and rotating the user in a manner that engages the desired muscle groups. The device can include electronically controlled actuators and/or electric motors for performing various motions associated with the user. A control unit can gather information regarding the user and the device to provide helpful information to the user or a caretaker. For example, the control unit can track progress over time, suggest the types and intensities of exercises for individual users, and prepare reports suitable for use in medical or insurance contexts.

A measuring device includes a base station, a weight station unit and a controller. A mount station unit is connected to the weight station unit and has first and second mounting bases connected by a swing arm. The first mounting base is moveably supported on the first weight scale, and the second mounted base is moveably supported on the second weight scale. An adjustable holding part is disposed at one end of the first mounting base and a support is disposed at another end of the first mounting base adjacent the swing arm. A sports article is mountable on the first mounting base between the adjustable holding part and the support.

Systems and methods are provided for enabling a split belt treadmill having two belts to self-pace. A feedback process estimates a first current step speed for a user on each belt by measuring stride length and step duration. A feed-forward process estimates a second current step speed for the user on each belt by measuring three forces and three moment components associated with foot contact with the belt. A command speed for each belt is produced by combining the first and second current step speeds with a Kalman filter. A belt speed associated with each belt is adjusted based upon the command speed.
