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 weight resistance exercise machine having cable and pulley linkage assemblies attached to a single weight stack. Each cable and pulley linkage assembly, which is independent of the other(s), can be used by one arm or leg during bilateral exercise training (that is, training in which both limbs of a pair are used to simultaneously to lift a weight). A tilt platform and biofeedback assembly display and measure in real-time how much each limb of a pair is contributing to such lifting effort.

A respiratory device of negative pressure type comprising a shell fastened to the user's chest and/or abdomen with minimal dead space, one or more vacuum and compressed air chambers attached to the shell; vacuum generating and compressed air generating sources connected to the vacuum and compressed air chambers respectively, one or more openings on the shell to allow exchange of the air enclosed between shell and user's body, with the vacuum and compressed air chambers; a valve shuttling between the vacuum and compressed air chambers. By having low dead space, pre-generated vacuum and compressed air close to the user, and the use of fast acting valves in some embodiments, the power requirement, weight, and size are reduced, making the device low cost and portable. In some embodiments, the vacuum and compressed air generating sources can be mounted on the shell itself, making the device ambulatory.

The present invention relates to apparatus and methods for warning a user about undesirable motion of a first portion of the user's body relative to a second portion of the user's body. In one representative embodiment, an apparatus for warning a user about motion of a first portion of the user's body relative to a second portion of the user's body comprises at least one sensor configured to measure the angle of the first portion of the user's body relative to a reference. The sensor is configured to be worn on the user's body, and is in communication with a controller. A warning mechanism is also in communication with the controller, and the controller is operable to activate the warning mechanism upon movement of the first portion of the user's body relative to the second portion of the user's body beyond a predetermined angle relative to the reference.

An embodiment of an exercise monitoring apparatus is shown. Herein, the exercise monitoring apparatus comprises a casing, a fastening member, a first laser device and a second laser device. The first laser device is oriented so that, when actuated, the device outwardly projects a first light beam in a direction substantially perpendicular to a top surface of the casing. The first light beam visually produces a line of light. The second laser device is oriented so that, when actuated, the device outwardly projects a second light beam in a direction substantially perpendicular to one of the sidewalls of the casing and substantially perpendicular to the first light beam.

The present invention discloses an intelligent household air purification cabinet type body-building apparatus, comprising a box body, a running machine, an air purifier and a power supply. The intelligent household air purification cabinet type body-building apparatus is further provided with an intelligent control system which comprises a controller, a central control computer, a pressure frequency detection device, an audio device, a display device and a signal receiving and transmitting device. A use method of the body-building apparatus comprises five steps of facility unfolding and need setting, environment preparation, body-building process, statistical analysis of body-building completion, and folding. The present invention has the advantages of small occupation space, complementary functions, no need of adding a power supply, supply of body-building environment beneficial to a human body, convenient operation and capability of long-term sustainable improvement.

An activity tracking racquet attachment device tracks activity such as calories burned over a period of using a racquet to which the device is attached. The device includes a housing having a first face and a perimeter sidewall extending from and around the first face. A processor is coupled to the housing. A motion detector is coupled to the housing such that the motion detector detects movement of the housing. The motion detector is communicatively coupled to the processor wherein the processor receives motion data from the motion detector. A coupler is coupled to and extends from a second face of the housing coupling the housing to an end of a handle of a racquet such that the first face of the housing faces outwardly from the end of the handle.

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.

A biofeedback belt system which serves as an alert belt with the ability to decrease stomach size as well as decrease the arch of a user-wearers lower back. The invention is designed for patients who have hyper lordosis conditions. The mechanism of the belt is based on biofeedback. When a user-wearer relaxes their abdominal region, the belt produces vibration or sound and the user-wearer must tighten their abdominal region to discontinue the vibration or noise. Biofeedback belt system can also work in a manner such that when the user-wearer tightens their abdominal region, the belt plays music or favorable vibration separately or together as encouragement. Over a period of time of tightening of the abdominal region on a regular basis, the abdominal region size decreases and abdomen strengthens.

Systems and methods are disclosed for correcting posture during certain movement patterns the systems and methods comprising a foot pad, at least one strap, a front of foot elevation device, and a toe strap; the front of foot elevation device further comprising a half cylinder with a flat side of the half cylinder affixed to the foot pad with a curved portion of the cylinder facing away from the platform, with a friction pad on the foot pad and a friction increasing layer on a lower surface of the unibody shell.
