Abstract: A wearable device and system has been developed to help users learn the practices of diaphragmatic breathing and breathing patterns to improve running and walking performance. The wearable has a breathing sensor (breathe in-breathe out) and a movement sensor used to identify foot strikes. A processor computes the number of foot strikes occurring while inhaling and the number of foot strikes occurring while exhaling to report breathing patterns as a function of time. The algorithms may be modified to teach breathing patterns to athletes in other sports and deep breathing for numerous movement and minimal movement applications.

Abstract: A system includes companion device that has movement sensors and a separate wearable device that has core contraction sensors. The companion device can be coupled to moving objects such as exercise equipment. Signals from the companion device and wearable device sensors are transmitted to a processor which analyzes the object movement signals and determines when a qualifying movement is performed which benefits from core contraction. Signals from the core contraction sensors are also transmitted to the processor and are used to determine if the core is contracted during the qualifying movement. If the core is contracted during the qualifying movement, the movement is a protected qualifying movement. However, if the core is not contracted during the qualifying movement the movement is an unprotected qualifying movement. The system can inform the user when unprotected qualifying movements are performed.

Abstract: A wearable device has a core contraction sensor. Signals from the core contraction sensor are transmitted to a processor which analyzes the core contraction signals and determines if the user's core is contracted or relaxed. The processor can cause a computing device to output a sequence of tones in response to a core contraction signal. The sequence of tones can correspond to a song which can be played by performing a plurality of core contractions with durations that correspond to a duration of the notes in the song. Alternatively, the core muscles can be contracted to correspond to music heard by the user. The processor can output a score based upon the matching of the core contractions with the musical notes.

Abstract: A wearable device and system has been developed to provide feedback to help users be able to engage specific muscle groups on cue, effectively exercise said muscle groups, and learn to engage said muscle groups before and through movements. Algorithms for identifying relaxed-to-engaged and engaged-to-relaxed transitions may be important for providing a positive user experience. The wearable device and system may be used for training effective use of the core and other muscles. A myokinesiometer is described to display target muscle engagement and body movement data simultaneously. The myokinesiometer facilitates specifying tests for protected and unprotected movement analyses.

Abstract: The system includes a movement sensor and a core contraction sensor in communication with a processor. The core contraction sensor is placed on the core muscles of a user and transmits core contraction signals to the processor. The processor receives movement signals from the movement sensor and identifies user movements that are qualifying movements that benefit from core contractions. The processor also monitors the timing between the qualifying movements and the core contractions to identify protected and unprotected qualifying movements. The system can also include a memory for storing core scores that are calculated from the protected and unprotected qualifying movements, exercise information and core sensor calibration information. The core contraction information can be used to calibrate the core contraction sensor. The core contraction and movement information can be transmitted to a therapist who can monitor the user's activities and provide instructional feedback.

Abstract: A wearable device has a core contraction sensor and a movement sensor which transmits signals to a processor which analyzes the signals and uses the data to control aspects of a video game. The core contraction signal may determine if the user's core is contracted or relaxed. A video game may be used with the wearable device to encourage usage of the core muscles with the player getting points or rewards for engaging their core muscles and properly timing the engagement of the core muscles with body movements. The wearable device may be used in place of, or together with conventional video game control devices. Developing the habit of using the core muscles during may be beneficial in back pain rehab and prevention, fitness training and wellness, athletic performance improvement, and reducing workplace injuries in occupations involving heavy lifting.

Abstract: A wearable device has a core contraction sensor and a movement sensor which transmits signals to a processor which analyzes the signals. The core contraction signal may determine if the user's core is contracted or relaxed. A video camera on a smart device may be used with the wearable device to record video of a user while data from the sensors on the wearable device are also recorded. The core contraction and movement sensor data may be sent to and viewed on the smart device display together with video of the user performing a movement. The simultaneous viewing of the video and sensor data may provide immediate feedback to the user regarding the timing of core contractions with body movements in an athletic, training, or therapeutic movement to allow the user to modify and improve coordination of core contraction with body movements to improve movement performance and achieve better results.

The first engaging member is movable between a first position in which the first engaging member pulls or draws the second engaging member toward the interior of the window assembly to force the second stile firmly on to the first stile throughout their length and a second position in which the first engaging member releases the second engaging member to allow the second stile off the first stile. The sash window assembly further includes means on the first stile for moving the first engaging member between the first and second positions in response to movement of a first fastener member between its locked and unlocked positions.

Abstract: A window latch comprises a cam keeper on one meeting window stile and a rotatable latch cam on the other meeting stile for locking engagement with the cam keeper. The latch cam has an actuator shaft operatively connected to a slide plate, which is movable along a straight line in response to rotation of the actuator shaft. The slide plate has a slot and fixed first engaging means. A base plate carries a locking feeler having second engaging means movable transversely of the direction of movement of the slide plate, the second engaging means normally engaging the first engaging means to prevent the movement of the slide plate. The slide plate and hence the latch cam are allowed to move when the locking feeler is pushed by said one meeting window stile to cause the second engaging means to disengage from the first engaging means into the slot.
