Abstract: Interchangeable primary massage heads for therapeutic treatment of body regions are mounted on secondary massage heads partially fitting inside of the primary massage heads. The secondary heads are fixed at proximal ends of intermediate mounting shafts in turn having distal ends fitting in or over drive shafts of percussive massage guns. Either primary or secondary massage head may be shaped as a bullet, disc, ball, spade, scraper, paddle or flexible net. A different embodiment is an adapter converter shaft formed as a secondary massage head shaped as a truncated conical cone with a center top hole sized to receive an intermediate mounting shaft on which a primary massage head is inserted. The adapter shaft has a distal end adapted to slip over short stroke drive shafts of compact massage guns enabling primary massage heads usage with either bigger or compact massage guns.

Abstract: A multi-directional expandable modular agility exercise ladder has spaced rows of two part paired rungs having overlapping ends joined to each by a pivot post forming a variable angle chevron prow. Outer ends of the paired rungs are interlocked to two parallel spaced bands to complete the ladder. A hook and loop pad interlock is used. Alternately, spaced key holes extend through the bands with the outer ends of the rungs having downwardly extending retainer poles secured in a respective key hole. Alternately, releasable spring clamps hand movable along the band length secure rung ends to the bands.

Abstract: A multi-purpose truncated triangular pyramidal shaped cone is used as a sports field marker having a multi-sided shape with sides sloping at approximately 102.5° upward for the support of a smartphone with camera(s) leaning against a side to provide a stable view and record a timed finish of an athlete crossing a finish line of a race. The smartphone is secured to a side of the cone by an intermediate clamp holder having tapered resilient plugs pressed into receiving holes in the cone side. In an alternate use, plural cones are used to hold ends of a horizontal hurdle bar. This bar is raised higher by stacking identical hollow cones forming a stack with a long pole extending through a hole in a flat top surface of a top truncated cone. The pole is secured along a vertical axis of the cone stack by set screws converging along their axes from holes on each side of the pyramidal cone. A bowed cradle is mounted atop the pole to hold the horizontal hurdle bar.

Abstract: The present invention measures jump heights using an IMU sensor module slipped in a pocket of a removable side ankle mount clip placed over any low, mid or high tops ankle athletic running shoe. A micro-processor in the IMU sensor module converts analog jump height data collected with real time digital signal processing to digital data sent to specialized algorithms loaded in a RF paired smartphone to refine the digital data to accurately calculate the height of the jump. The clip has two downward spaced legs joined by a curved arch at the top with a first leg being flexible and fitting snugly against a wearer's ankle below the fibula bone with the curved arch resting over the shoe's collar. The second leg has a foot extending outwardly from the curved arch to form a pocket with a top opening to receive and snugly hold the module.

Abstract: An athlete wearing footwear measures jump heights with a motion sensor mounted on the footwear over toes of the athlete. By sensing vertical jump start motions the sensor detects jump start and finish times of ?4 g start and ?4 g landing. The sensor, a body wearable mems sensor developed by JAWKU, L.L.C., has a previously installed generic factory scale calibration factor. The athlete replaces this calibration factor with a new calibration scale factor selecting an “absolute” external reference device which measures jump height. This device measures several jump heights then inputted to an algorithm app in the sensor to calculate the new calibration scale factor customized to the actual athlete. The motion sensor has built in programming apps to periodically receive an upgraded factory scale calibration factor which upgrade is based on an ever increasing data pool of jump heights.

Abstract: A universal 6-DOF mems sensor combined with six degree of motion algorithms and human motion parameters permits individualized real time motion analysis of a user to enable accurate measurements. Data derived thereby is wirelessly sent for viewing to a Bluetooth® enabled smartphone or combination smartphone and eyeglass device, such as the Google Glass® headset. The sensor is worn on a wrist or ankle band or in combination with a chest mounted cardio heart rate monitor dependent on the biometric parameters measured. Typical physical exercise data gathered includes reps, sets, 10-100 yard dash times, vertical, horizontal and broad jump distances, a range of shuttle times, RAST, steps taken, distance traveled, velocity, acceleration, and calories burned. The heart rate monitor provides cardio assessment and the 6-DOF sensor measures a runner's pace and cadence data.

Abstract: An athlete (1) measures sprint time by locating a smartphone (3) having a camera and crystal oscillator clock which is first activated at the finish line. The sprint end time is recorded by a photo stamp time app activated by a video trigger causing the smartphone (3) to send a RF stop event signal to the athlete's wrist mounted motion sensor (2). Before this a sensor timer or clock is started via the sprinter's start event. The sprinter's start activates the sensor's clock and saves the captured start time including time drift error. Upon the phone app selecting the run time function, a sync command sent to the sensor (2) by the app zeros out the phone and sensor timers. A one-time crystal calibration routine correcting for drift errors caused by the smartphone's operating system is activated which provides the sprint with a corrected start time.

Abstract: An athlete measures sprint time by locating a smartphone having a camera and clock start button which is first activated at the finish line. The sprint end time is recorded by a photo stamp time app. This sprint end time activates a video trigger causing the smartphone to send a RF stop event signal to a wrist mounted motion sensor worn by the athlete. A sensor timer is started via the start event by track or self starting. In track starting, the athlete pushes a start button on the sensor to initiate a variable 2-5 second delayed sound READY-SET-GO series of beeps to start the sprint. In self starting, the sensor detects threshold motion parameters of the sprinter's start which activates the sensor's free running clock and saves the start time. The time base on the sensor is used to calculate run time.

Abstract: A headset is disclosed having a transmitting unit for each ear. Each unit (2) mounts a first bone vibration sensor (3) in the external auditory canal and a second bone vibration sensor (7) next to the jawbone/skull. Controls on a housing module (4) activate either sensor. The first sensor is moveable outside the auditory canal by a flexible support attached to the module. A digital speech processor shared by both sensors is mounted within the module. Two-way communication is maintained between the user and an external source (40), such as a cellular telephone which has a multi-task processor with memory and applications stored therein for receiving and transmitting user voice commands and text messages. A recently developed Bluetooth® protocol transmitter (50) and antenna used with the external source permits digital wireless simultaneous synchronization signals to be sent to both units for true stereo sound.

Abstract: Digital musical footwear is disclosed having hidden compartments which house a thin integrated multi-plane electronic circuit board assembly (2) and a rechargeable lithium ion battery pack. A transmitter antenna is attached to a hand held device such as a smart phone which antenna sends wireless short wave sound signals to a receiving antenna part of the circuit board assembly. Multiple mini-speakers (6, 7) are footwear mounted to play the music. Bluetooth® version 4.0 wireless protocol technology is employed in the circuit board assembly. The circuit board can be flat and hidden in a recess of a heel or curved and hidden in a wall recess of the footwear as can the battery pack.
