Provided is a mask apparatus. The mask apparatus includes a mask body in which a microphone and a speaker are installed, a face guard coupled to a rear surface of the rear body so as to be in close contact with a user's face and having a breathing space therein, a pressure sensor installed in the mask body to measure a pressure of the breathing space, and a controller configured to compare a current pressure value measured by the pressure sensor to a reference pressure value and control a voice output of the speaker based on a difference between the current pressure value and the reference pressure value.

The present invention relates to a vest (1), comprising a strap (2), which is characterized in that the strap (2) comprises a lockable lock (2.1).

A remote engagement system for a live event occurring at a venue includes an output device located at the venue or remotely from the venue for providing audio and/or visual output to at least one recipient. A controller receives signals, such signals being representative of physical reactions of remote viewers and being transmitted from a plurality of user input devices located remotely from each other and from the venue and controls the output device located at the venue or remotely from the venue to provide an audio and/or visual output to people at the venue or located remotely from the venue.

A wearable device in the form of a tee-shirt is described. The sleeves of the tee-shirt having an electrocardiogram (ECG) sensor, a photoplethysmogram (PPG) sensor or a ballistocardiogram (BCG) sensor for monitoring the pulse of a person wearing the tee-shirt. The tee-shirt makes possible the comparison of the pulses down the two arms. The pulse-transit-time, pulse amplitude, pulse spread and pulse shape may be compared to observe any difference between the left and right sides of the person.

A face mask can both actively cancel sounds and passively attenuate sounds spoken by the user to prevent the sounds from reaching non-intended recipients positioned near the user. The mask can not only reduce the user's voice from escaping the mask but can also be used to reduce external sounds from reaching inside the mask. Thus, a user can wear the mask in public and talk on their phone without disturbing others around them. The mask can include at least one microphone and at least one audio speaker disposed inside and/or outside the mask. Sounds received by the microphone can be processed by a microphone and computing electronics to provide an output to the audio speaker that can appropriately attenuate the sound received by the microphone, via acoustic cancelation. The mask can not only be used to cancel sounds but may also be used to amplify sounds when desired.

A video recording device, holster and article of clothing are disclosed to reliably and covertly provide for the capture of video, audio, and metadata, and perform other commands. The holster may be provided with a carrier that is, in turn, inserted into the holster. In one embodiment, the holster may be confirmed as being associated with the video recording device to authenticate a user, and establishes a docked position. Moreover, the video recording device may enter a mode of operation associated with using the video recording apparatus automatically when inserted into a holster.

The wearable article 200 comprises a sensing component. The electronics module 100 is removably coupled to the wearable article 200. The electronics module comprises a housing and a processor disposed within the housing 101. An interface element 121, 123 interfaces with the sensing component so as to receive signals from the sensing component and provide the same to the processor. A sensor 105 is disposed within the housing 101. The sensor 105 monitors a property of the environment external to the electronics module 100 through the housing 101. The housing 101 is constructed such that the sensor 105 has line of sight through the housing 101.

A zipper-type circuit fabric and smart clothes composed thereof include a clothes body. The clothes body is made of waterproof conductive fabric body. The waterproof conductive fabric body includes a plurality of conductive wires and conductive contacts. Rectangular elongated conductive media and folded conductive media are arranged inside the conductive wires so that the conductive media are stable and ductile. The clothes body is further provided with a waterproof zipper body. The zipper teeth on the waterproof zipper body are all electrically connected to the conductive wires. When the zipper body is closed, a metal probe on a zipper tooth is placed into a connecting slot so that the left and right sides of the clothes body form a closed circuit. The clothes body can be connected to glove bodies and includes a plurality of flexible sensors internally.

A combined air filter and protective gown includes a protective gown; at least one tube; at least one air filter; a waist belt; check valves disposed at a face, two hands, and two ankles of the protective gown respectively; and ties for fastening the face, the hands, and the ankles of the protective gown respectively. One end of each tube is terminated inside the protective gown and the other end thereof is attached to the air filter. Each air filter is attached to the waist belt. Each air filter includes a centrifugal fan, a circuit board, a UV lamp, a filter element formed of activated carbon, a power supply, a housing for enclosing the centrifugal fan, the circuit board, the UV lamp, the filter element, and the power supply, and a cover threadedly secured to the housing.

Systems and methods for prescribing athletic activity to be performed by a user, and for adapting the prescribed athletic activity based on completed (e.g. ongoing) athletic performances by the user. A coaching plan may be automatically created that prescribes personalized athletic activities as a user trains towards a goal date. The athletic information may be received from one or more sensor devices associated with a user, and the coaching plan may be continuously or intermittently updated based on the received sensor data.
