A device for indicating appropriate social distancing includes the ability to project light (in various forms and in a various ways) onto the ground in a manner visible by the user and those around them. A boundary of the projected light can be set to an acceptable social distance and can include different colors to indicated varying social distances for varying levels of trusted individuals. Proximity sensors set to appropriate distancing requirements, along with the varying levels of trust can be implemented into multiple devices being used in a group setting.

A helmet including a protective head covering, information carrier, adhesive, and flap. The information carrier includes a first panel having a terminal edge, and a second panel having a fold line. The second panel is joined to the first panel to define a pouch having an interior space and an opening to the interior space. The opening is defined by the terminal edge disposed proximately to the first panel below the fold line. The adhesive is configured to affix the first panel to the exterior surface. The flap is pivotally attached to the second panel about the fold line, wherein the second panel is bendable away from the exterior surface at least between the terminal edge and the fold line to enable the flap to pivot about the fold line toward the exterior surface in connection with insertion of the flap into and removal of the flap from the opening.

A non-transitory computer-readable storage medium storing computer-readable instructions which, when executed by a processor of a computing device, cause the computing device to carry out a method. The method comprises obtaining sensor data indicative of a parameter sensed by a sensor associated with an article of sports equipment; obtaining position data indicative of a spatial position of the sensor or of the article of sports equipment; jointly processing the sensor data and the position data to derive a hybrid metric; and outputting a signal conveying the hybrid metric on a network or storing the hybrid metric in a computer-readable memory. The sensor data and the position data may be time-aligned to a common time reference, so that the jointly processing is carried out on the time-aligned sensor data and position data. The hybrid metric measures properties that are not derivable from the sensor data alone or the position data alone.

Various embodiments of safety headwear are provided. The safety headwear includes one or more of a hard hat, such as a safety helmet, and a respirator. The safety headwear monitors one or more conditions, such as biometric and/or atmospheric conditions. The safety headwear analyzes the results of the monitoring to determine whether to generate an alarm to the wearer of the safety headwear.

A protective suit comprising: a head portion comprising a fluid-filled head portion chamber; a neck portion releasably secured to the head portion and comprising a neck portion chamber, wherein the fluid-filled head portion chamber is in fluid communication with the neck portion chamber; and a torso portion releasably secured to the neck portion and comprising a fluid-filled torso portion chamber, wherein the fluid-filled torso portion chamber is in fluid communication with the neck portion chamber; and wherein the head portion is configured to be disposed on a head of the wearer, the neck portion is configured to be disposed in an arcuate manner around a neck of the wearer, and the torso portion is configured to be disposed on a torso of the wearer, such that when a force of an impact is received on the head portion, fluid from the fluid-filled head portion chamber is transferred into the neck portion chamber to support the neck of the wearer against translational and rotational forces imparted to the wearer, and when a force of an impact is received on the torso portion, fluid from the fluid-filled torso portion chamber is transferred to the neck portion chamber to support the neck of the wearer against translational and rotational forces imparted to the wearer.

Embodiments of the invention disclosed herein are directed to articles of clothing that allow for monitoring of different analytes (e.g., electrolytes and molecules) in human sweat during fitness activity, while training, or simply in everyday life. The clothing includes a sensor system completely integrated in textile such that every sensing part is made of textile fibers. The clothing is able to control, collect, analyze, and expel the sweat over time. The textile sensor allows a spontaneous absorption of body sweat directly from the skin, while it is produced, using the hydrophilic natural properties of the textile. Then, once adsorbed, the flux of sweat is controlled and guided through the textile using a gradient of the textile's hydrophilic properties. The sweat guided through the textile is analyzed through an electrochemical sensor woven into the textile. Finally, the sweat is collected in a reservoir and expelled for evaporation.

Described are various embodiments of an air-speed sensor, system and airspeed monitoring process digitally implemented thereby or in relation thereto. In one such embodiment, a sensor comprises a sensor casing having a leading surface and having plural distinctly oriented input ports defined therein to capture a respective air pressure at each one thereof; respective pressure sensors disposed within said casing in fluid communication with respective ones of said input ports to sense said respective air pressure for each one thereof; and a digital processor operatively coupled to each of said pressure sensors to digitally compute respective pressure ratios between said input ports and compare said ratios against designated pressure ratios corresponding to designated incident airspeed angles of incidence to output an airspeed incident angle and airspeed accordingly.

Embodiments of the present disclosure may provide methods and systems enabled to perform the following stages: receiving a plurality of content streams; retrieving metadata associated with each of the plurality of content streams; processing the metadata to detect at least one target annotation within at least one target content stream; retrieving telemetry data associated with the at least one target content stream; processing the telemetry data and the metadata associated with a plurality of frames in the at least one target content stream to ascertain vector motion data; and mapping a spatial relationship associated with at least one capturing device associated with at least one target content source.
