Abstract: A automatic unlock device for tourniquet, includes a lock structure for setting the tourniquet in tight state, an unlock device for unlocking the lock structure and setting the tourniquet in loose state, and a control circuit for controlling the unlock device. The unlock device is connected with the lock structure, the drive part of the unlock device is connected with the control circuit, and the drive part drives the unlock device to lock or loose the lock structure. When in use, the lock structure is buckled with the unlock device to reduce the length of the tourniquet, that is, in tight state. Simultaneously, the control circuit can be manually or automatically set the unlocking time and start timing. When the time is up, the control circuit outputs a control signal to the drive part to drive the unlock device releasing the lock structure.

Abstract: A thermal protection plug, provides a temperature sensor I, which is directly contact with the neutral wire terminal, so as the heat transferring from neutral wire terminal to the temperature sensor keeps prompt and improve the response delay to cut-off the power switch. And because the negative pole of DC is collinear with the neutral wire terminal, it means that the temperature sensor I can use a low voltage isolation sensor and it is safer even though the breakdown between the shell and the pins of the temperature sensor I.

Abstract: A smart hydration reservoir includes a flexible sensor which can be attached to the outer surface of any kind of the hydration reservoir and monitor changes of capacitive data of the hydration reservoir while user drinks the liquid which makes changes of the liquid level. The capacitive data is inputted into the controller; the controller will calculate the liquid level and then send out the information of the liquid level to the hand held device, such as specified display or mobile phone. Thus, the user can easily notice the liquid level of the hydration reservoir. The whole hydration detecting assembly can be easily installed to any hydration reservoir bought from the market.

Abstract: An electronic mask with negative pressure includes a mask body, the mask body is provided with a negative pressure cavity, the negative pressure cavity covers mouth and nose, and at least one fan for forming negative pressure in the negative pressure cavity is provided, the power plug of the fan is connected to a control circuit, a first filter device is set to cover the fan; when the fan starts, the air is filtered and evacuated to outside. During the exhaust process, the water vapor in the negative pressure cavity is also discharged, which can effectively reduce the humidity in the negative pressure cavity to ease dyspnea of patients with respiratory diseases and will not increase the burden of breathing. The negative pressure design makes the air exhaled by the human body must be filtered before being discharged without leaking through the gaps of the mask. If the patient wears the mask, it can effectively prevent the spread of viruses or bacteria.

Abstract: A method of assigning identification codes to devices, each device including a controller, a memory, and a switch, with the devices connected in a series circuit. The method includes opening all of the switches, supplying a signal, including an identification code, to the first device of the series circuit and storing the identification code in the memory of the first device, closing the switch of the first device to connect to the next device in the series circuit, sending an acknowledgement to the series circuit, and repeating the process for each of the devices, successively, for each of the devices in the series circuit, and assigning a different identification code to each of the devices.

Abstract: A method of controlling respective intensity levels of each of N light units, from a first light unit to an Nth light unit. Each of the light units has respective intensity levels from a 0 level to an L level based on duration of illumination of each light unit, In the method, a control signal representing light intensities for each of the N light units, sequentially, in order, for the first light unit to Nth light unit is received and processed. Then, the light units are re-arranged in accordance with the light intensities into a re-arranged order, from level L to level 0. A predetermined time period is counted sequentially through L time intervals. The light units are turned on in the re-arranged order at respective time intervals corresponding to the light intensities; and all light units are turned off at the end of the predetermined time period.

Abstract: A method of sealing a first part to a second part of an enclosure. The first part is a metal extrusion having a channel-shaped cross-section and the second part is a light-transmissive plate, together forming the enclosure. An electrical light source located in the enclosure shines light through the light-transmissive plate. The sealing method includes placing an elongate seal member into a groove of a first part of the enclosure, extending along the groove, and inserting an edge of a second part of the enclosure into the groove of the first part.
