Abstract: An attachment (24) for a sewing machine (10) to provide simultaneous sewing and sealing of a seam comprises a reel (23) for dispensing a strip of adhesive thermoplastic polymer (25) between fabric members (7,9) to be sewn. A plurality of heated driven rollers (40, 42, 44) opposed to heated idler rollers (50) having a continuous belt (52) thereover collectively exert heat and pressure on the seam, melting the polymer strip (25) so as to seal the seam. Thread (17) having been treated with adhesive thermoplastic polymer may be employed to seal the punctures in the fabric made by the sewing machine's needle (19). The driven rollers are driven in synchronization with the operation of the sewing machine and are engaged with and withdrawn from the seam responsive to operator command.

Abstract: A charging device for wirelessly charging an electronic device has a wireless power receiver antenna. The charging device includes a battery having a front surface and a back surface. The charging device has a first antenna comprising a wireless power transmit antenna or a dual-mode antenna. The first antenna is configured to wirelessly transmit power. The charging device has a second antenna. The second antenna includes a wireless power receiver antenna or a dual-mode antenna. The first antenna is configured to wirelessly receive power. The charging device also includes a housing encapsulating the battery, the first antenna, and the second antenna. The housing has a front contact surface opposed to a rear surface, and the contact surface has a coupling portion configured to couple the charging device with the electronic device. The first antenna is closer to the contact surface, and the second antenna is closer to the rear surface.
