Abstract: A detachable adjustable mouth mask includes a base frame member, a shade fastened to the base frame member to provide a curved, surface for covering over the user's mouth and nose, a chin support connector providing a clamping groove and friction ribs for fastening to the base frame member and lugs with radial teeth, a chin support providing connection members pivotally coupled to the lugs of the chin support connector with radial teeth thereof angularly adjustably engaged with the radial teeth of the chin support connector and a spacer block providing a ventilation passage for exhaust of exhaled air, and a pair of ear loops for securing the chin support to the user's ears.

Abstract: A mouth mask includes a base frame member configured to fit the curvature of a human face, a shade fastened to the base frame member to form with the base frame member a curved surface for covering over the user's mouth and nose and having a notch on the middle part of the top side thereof around the user's nose to enhance wearing comfort, a chin support directly and angularly adjustably coupled to the base frame member or vertically and angularly adjustably coupled to the base frame member by means of an adapter member and defining with said base frame member an air hole for guiding out the user's exhaled air, and a set of ear loops respectively connected to the two ends of the base frame member for hanging on the user's ears.

Abstract: A tire monitoring system with a wireless setting capability includes a wireless controller and a plurality of tire status sensors each tire status sensor is composed a sensing and processing unit having an unique tire serial number, a second low frequency transceiver and an RE transmitter. The wireless controller has a first low frequency transceiver and stores a plurality of tire serial numbers representing different wheel positions. The wireless controller outputs a control signal including a reset command and a new tire serial number to a specific tire status sensor. The sensing and processing unit will be reset and replace the tire serial number when the tire status sensor receives the control signal.

Abstract: A tire monitoring system with a wireless setting capability includes a wireless controller and multiple tire status sensors each of which is composed a sensing and processing unit having an unique tire serial number, a low frequency transceiver and an RF transmitter. The wireless controller also has a low frequency transceiver and stores multiple tire serial numbers representing different wheel positions. The wireless controller outputs a control signal including a reset command and a new tire serial number to a specific tire status sensor. The sensing and processing unit will be reset and replace the tire serial number when the tire status sensor receives the control signal.

Abstract: A helmet having detecting tire status capability has a body with a face guard, a controller, a projector and a power circuit. The controller receives current tire status signals from tire status sensors in the wheels and further displays the current tire status value on the face guard and detects whether the tire status signals are abnormal. If a tire status signal is abnormal, the controller drives the projector to display a warning word or symbol on the face guard. The rider sees real-time information about the wheel so the rider can handle developing situations with the wheels.
