  • Patent number: 11130353
    Abstract: A system for printing at least one stretchable ink on a thermoformable substrate including a first surface and a second surface opposite the first surface. The system includes an unwinder, a printing module and a rewinder. The unwinder is arranged to feed the thermoformable substrate from a first roll into a printing module. The printing module includes a flood coater arranged to deposit a coating layer on the first surface of the thermoformable substrate. The rewinder is arranged to receive the thermoformable substrate and to form the thermoformable substrate into a second roll.

  • Publication number: 20210289255
    Abstract: Media content can be synchronized across multiple participant devices. A set of participant devices may request access to stream media content from a content delivery network. Each participant device can send information relating to the playback of the media content to a coordination server. The coordination server can determine a synchronized time for playback of the media content such that all participant devices playback the media content simultaneously. The coordination server can instruct each participant device to playback the media content according to the synchronized time.

  • Publication number: 20210083592
    Abstract: Briefly, a voltage doubling variable frequency drive includes an active converter connected to a DC bus that is connected to a first inverter that converts DC power to variable frequency, three-phase AC power, and variable frequency, three-phase AC power to DC power, and to a second inverter that converts DC power to three-phase AC sine wave power. The converter converts single-phase AC power to DC power and DC power to single-phase AC power and maintains a selected voltage on the DC bus. The converter has an active rectifier and a controller that drives the rectifier with a pulse width modulation according to a switching scheme that switches the rectifier according to an adaptive hysteresis control to maintain constant switching.

  • Patent number: 10931205
    Abstract: A phase converter that converts single phase AC electric power to balanced three phase AC power. Two input terminals are connectable to a single phase AC power source, and connect directly to two output terminals of the converter. The phase converter has a storage capacitor, three active half bridge modules connected to the storage capacitor and a controller. Two modules connect to the input terminals and charge the storage capacitor. The other module connects to a third output terminal. The controller switches the module connected to the third output terminal and one of the other modules to generate and shape a second phase and a resultant third phase.

  • Patent number: 10596718
    Abstract: A handheld mortise forming device includes a base unit having a first support extending parallel to a first axis. The first support includes first and second working ends. A first sidewall and a second sidewall are connected to the first support. One of two connecting units is rotatably mounted to the first sidewall. The other connecting unit is rotatably mounted to the second sidewall. A second support extends parallel to the first axis and is connected to the two connecting units. The second support is rotatable relative to the first and second sidewalls and includes an abutting face. A clamping unit includes a pressing member located on a side of the second support adjacent to the abutting face. The pressing member can clamp lumber. The pressing member is jointly rotatable with the second support and is switchable between the first working end and the second working end.
