One or more computing devices, systems, and/or methods for calibrating barometric sensors and/or determining altitudes of devices are provided. In an example, a device is determined to be outdoors. In response to determining that the device is outdoors, a calibration process associated with a barometric sensor of the device is performed. The calibration process includes performing one or more barometric measurements using the barometric sensor to determine one or more barometric pressure measures, determining one or more locations of the device, wherein the one or more locations are associated with the one or more barometric measurements, and determining a barometric offset based upon the one or more barometric pressure measures and one or more reference values. An adjusted barometric pressure and/or an altitude of the device is determined based upon a first barometric pressure measure and the barometric offset.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a battery system configured to provide power for the MIDS, a display system, and a processor communicatively coupled to the display system and configured to display information to an eye of a wearer of the eyewear via the display system. The display system is disposed inside a space bounded by a first vertical line that bisects the eyewear and a right line or a left line that extends no more than 40 mm from the first vertical line.

Training at the proper level of effort is important for athletes whose objective is to achieve the best results in the least time. In running, for example, pace is often monitored. However, pace alone does not reveal specific issues with regard to running form, efficiency, or technique, much less inform how training should be modified to improve performance or fitness. A sensing system and wearable sensor platform described herein provide real-time feedback to a user/wearer of his power expenditure during an activity. In one example, the system includes an inertial measurement unit (IMU) for acquiring multi-axis motion data at a first sampling rate, and an orientation sensor to acquire orientation data at a second sampling rate that is varied based on the multi-axis motion data.

A sport apparatus comprising a shaft, wherein the shaft comprises a notch fitting and a sensor housing. The sensor housing comprises an alignment rib fitting, printed circuit board, rechargeable battery, one or more motion sensors, a transceiver, an inductive charging coil, among other necessary elements for the sport apparatus as described herein. A portion of the sensor housing resides within the shaft, wherein the alignment rib of the sensor housing mates with a notch or other locking mechanism of the shaft.

Provided is an analysis apparatus for analyzing a behavior of a ball that has a center of gravity and in which an acceleration sensor is installed at a position shifted from the center of gravity by a predetermined shift amount, the analysis apparatus including a control unit configured to derive a centrifugal acceleration that is applied to the acceleration sensor, based on acceleration data that is output by the acceleration sensor, and derive at least one of a direction of a rotation axis and a rotation speed of a spin of the ball, based on the predetermined shift amount and the centrifugal acceleration.

A system, method, and wireless earpieces for implementing a virtual assistant. A request is received from a user to be implemented by wireless earpieces. A virtual assistant is executed on the wireless earpieces. An action is implemented to fulfill the request utilizing the virtual assistant. The wireless earpieces may be a set of wireless earpieces and the virtual assistant may be implemented independently by the wireless earpieces.

A system includes a minimally intrusive display system (MIDS) configured to be disposed on an eyewear. The MIDS includes a display system and a sensor system configured to provide for a sensor data. The MIDS further includes a processor configured to process the sensor data to derive a physiological measure. The processor is further configured to display, via the display system, the physiological measure, wherein the display system is disposed in the eyewear so that the physiological measure is only viewed when a user of the eyewear turns the user's pupil towards the display system at angle α from a forward direction.

A ball glove may include a front glove portion, a back glove portion and a webbing. A palm side of the webbing comprises a spin reduction texture. The spin reduction texture includes a first pattern of raised projections and/or recesses.

The invention is comprised of a differential air pressure exercise system, comprising: a base; a pair of uprights on the base dividing the base into a front portion and a rear portion; a bulkhead extending between and vertically moveable relative to the uprights; a right arm attached to the bulkhead extending from the bulkhead towards the base rear portion; a left arm attached to the bulkhead extending from the bulkhead towards the base rear portion; a chamber support frame coupling element on the right arm; a chamber support frame coupling element on the left arm; at least one hinge coupled to the bulkhead between the left arm and the right arm; a chamber support frame extending between the left arm and the right arm, the chamber support frame coupled to the at least one hinge to move between an engaged condition wherein a portion of the chamber support frame is coupled to the chamber support frame coupling element on the right arm and a portion of the chamber support frame is coupled to the chamber support frame coupling element on the left arm and a lowered condition wherein the chamber support frame is uncoupled from both the chamber support frame coupling element on the right arm and the chamber support frame coupling element on the left arm.

Disclosed are a joint manipulation device and system for increasing the range of motion of a joint of a user, and monitoring the compliance of the user's operation of the joint manipulation device to standards or guidelines set by a monitoring entity. Certain sensors associated with the joint manipulation device may cause an indicator to transmit an alert to the user based on whether or not the device is sufficiently engaged with a limb or joint of the user to be considered in compliance. Additionally, progress data associated with the range of motion of the user's joint may be obtained by a sensor assembly and transmitted to one or more systems associated with the device system. Progress data obtained during a period of non-compliant use of the device may be excluded from the transmitted data, thereby generating a set of compliant progress data for accurate analysis of device effectiveness.
