Abstract: The various implementations described herein include a video camera assembly that includes: (1) a housing; (2) an image sensor encased in the housing and configured to capture activity of the smart home environment; (3) a wireless radio configured to transmit video frames captured by the image sensor to an electronic device via a remote server; (4) at least one infrared transmitter configured to selectively illuminate the smart home environment; (5) one or more circuit boards encased in the housing, the one or more circuit boards including at least one processor mounted thereon; and (6) a heating component coupled to the image sensor, the heating component configured to continuously maintain the image sensor at a temperature above a threshold temperature while the image sensor is capturing the activity of the smart home environment.

Abstract: A tube joint for connecting two pipes comprises two enlarged openings formed at two pipes to be connected; a sealing pad between the two enlarged openings; each of two ends of the sealing pad are formed with a reduced stepped portion; a shape of the stepped portion being matched to the enlarged openings so as to be received in the enlarged opening; thereby the stepped portion can seal the enlarged opening; a middle section of the sealing pad being between the two reduced stepped portion and being protruded between the two enlarged openings; and two covering plates. Each covering plate encloses around a periphery of the enlarged opening and a periphery of the middle section of the sealing pad. Two first annular lips are installed around an outer periphery of the stepped portions of the sealing pad, and each sealing pad may be formed with a second annular lip.

Abstract: A method for manufacturing a fluoropolymer compound plate comprises the steps of: combining a fluoropolymer sheet and a medium plate as a fluoropolymer compound plate; transferring the fluoropolymer compound plate to a preheat section for being heated uniformly in a lower tension, transferring the fluoropolymer compound plate to a melting section for heating the fluoropolymer sheet of the fluoropolymer compound plate; transferring the fluoropolymer compound plate to a pressing section by rollers; and compressing and annealing the fluoropolymer compound plate. A device for performing the method comprises a plurality of tension adjusting axial seats; a plurality of roller; a pair of first guide wheels; an upper and a lower layer radiating heater; a third guide wheel set; an upper and a lower layer high temperature radiating heater; a guiding roller; a shaping heater; a plurality of temperature controller roller sets and a product winding wheel.

Abstract: A fluoropolymer compound plate comprises a fluoropolymer sheet; and a medium welded with a net having a low expansion coefficient; then the fluoropolymer sheet combined with the net through welding operation so as to be formed as a fluoropolymer compound plate. The medium is a welding film. Another surface of the net not welded to the fluoropolymer sheet is welded with a piece of fabric cloth through another medium for being combined with another material.
