Abstract: The disclosed technology controls a digital inking device by communicating electrostatic inking signals between the digital inking device and an ink-receiving computing device in an inking mode enabling the digital inking device to render digital ink in a display of the ink-receiving computing device via the electrostatic inking signals, detecting proximity of a peripheral communication device relative to the digital inking device, transitioning the digital inking device from the inking mode to a non-inking mode that terminates communication of the electrostatic inking signals between the digital inking device and the ink-receiving computing device, based at least in part on the detecting operation, and communicating electrostatic data signals in the non-inking mode between the digital inking device and the peripheral communication device in the non-inking mode, based at least in part on the transitioning to the non-inking mode.

Abstract: An optoelectronic apparatus includes an array of emitters configured to emit beams of optical radiation. An optical substrate is mounted over the array. An optical metasurface is disposed on the optical substrate and configured to collimate and split each of the emitted beams into a respective group of collimated sub-beams, and to direct the collimated sub-beams toward a target to form a pattern of spots on the target.

Abstract: A tube for dispensing a material such as toothpaste has a tube wall with a sealed first end and s second end having a dispensing opening. A plurality of rows of cooperating fasteners are disposed in plural columns along opposite sides of the tube wall. As the tube is rolled up during consumption of the material therein, the fasteners are brought into juxtaposition with each other and mated together to secure the tube in the rolled up position. The fasteners may be male and female snaps that are integrally molded into the tube side walls during manufacture of the tube.
