Embodiments of portable electronic device holders and methods of manufacture of portable electronic device holders are generally described herein. Other embodiments may be described and claimed.

An apparatus for demonstrating how golf balls interact with golf clubs includes a downswing plane, a club shaft attached to the downswing plane, a golf club head attached to the club shaft, and a collision-plane indicator attached to the golf club head wherein the collision-plane indicator illustrates the plane created by two intersecting lines that are in the direction of the path and the direction of the club face. Preferably, the downswing plane has an adjustable angle, and preferably the downswing plane swivels. Preferably the club shaft is pivotally attached to the downswing plane. Preferably the apparatus includes a removable golf ball with a spin axis through the middle of the ball, and with a black line across the middle of the ball that indicates spin direction perpendicular to the ball's spin axis.

In a first aspect, a system for monitoring a swing is provided that includes (1) a swing measurement device adapted to couple to a swinging object and to output a signal indicative of a characteristic of the swinging object; (2) a wireless transmitter coupled to the swing measurement device and adapted to wirelessly transmit the signal output by the swing measurement device; and (3) a wireless device adapted to receive the wirelessly transmitted signal and to provide information regarding the swinging object based on the received signal. The wireless device is a cellular telephone or personal digital assistant (PDA). Numerous other aspects are provided.

The present invention is a Golf Super Tag Multifunction Golf Swing Capture and Analysis device comprised of a printed circuit board mounted in a case attached to the end of the club grip or mounted along the club shaft containing sensors and electronic components. The sensor data associated with the golf club swing is processed by the microcontroller firmware that analyzes the physics of the golf swing to determine the various characteristics of the golf swing such as swing plane, club face orientation, club head speed, point of ball impact, etc. This data can be stored in onboard memory and/or relayed via Bluetooth Low Energy or other communication protocols for storage, further application processing and/or relay to web-based systems. The firmware is comprised of code that runs on the microcontroller to handle the microcontroller startup, wake up, power management, sensor control and sensor data, as well as Bluetooth (or other communication protocols).

In a first aspect, a method for monitoring a golf swing is provided that includes coupling a mobile telephone to a golf club and employing the mobile telephone coupled to the golf club to monitor acceleration of the mobile telephone as the mobile telephone swings while a user swings the golf club, collect acceleration information based on the monitored acceleration of the mobile telephone as the mobile telephone swings, analyze the collected acceleration information to determine one or more characteristics of the golf swing based on the collected acceleration information, and output information regarding the one or more characteristics of the golf swing on the display of the mobile telephone. Numerous other aspects are provided.

A golf club having a sensor that is releasably connected is disclosed, where the sensor comprises a plurality of inertial measurement units. Each inertial measurement unit is able to measure linear accelerations along three orthogonal axes and angular rates of rotation along the same three orthogonal axes. Each inertial measurement unit is positioned such that at least two of the axes of each inertial measurement unit are oriented differently. Additionally, a process may be implemented by a processor to expand the measurement range of the sensor.
