  • Patent number: 10847384
    Abstract: Development of smart objects with electronic functions requires integration of printed components with IC chips or dies. Conventional chip or die bonding including wire bonding, flip chip bonding, and soldering may not be applicable to chip or die attachment on low temperature plastic surfaces used in physical objects. Printing conductive connection traces requires a smooth interface between contact pads of a chip and the surface of the physical object. In order to address this issue of chip/die attachment to a physical object, this disclosure provides embodiments to construct a fixture on a chip or die for attachment and electrical connection onto a physical object by printing operations and/or ACF bonding methods.

  • Patent number: 10825855
    Abstract: Bending a flexible x-ray detector to image a curved structure or object will distort the object appearance when compared to an image captured by a flat/rigid detector. An image distortion of this type can be corrected when the shape (relative bend position) of the x-ray detector is known. Incorporating strain sensors on the flexible x-ray detector makes it possible to record the local bend of the flexible x-ray detector when an image is taken. This shape information can be used to either label or correct for the image distortions created by bending the x-ray detector to assist users more accustomed to viewing images produced by flat/rigid x-ray detectors.

  • Patent number: 10827092
    Abstract: A multi-function printer is coupled to a mobile device via a proximity network interface. The multi-function printer determines a workflow specified by a user of the mobile device. An ephemeral token associated with the workflow is sent to the mobile user device. The mobile device uses the ephemeral token to create a payment packet that is sent to a payment server which sends a receipt in response thereto. The multi-function printer receives the receipt from the mobile device and in response to receiving the receipt, obtains a list of payments from the payment server. The multi-function printer performs the workflow based on validating the receipt against the list of payments.

  • Patent number: 10802775
    Abstract: One embodiment provides a system for facilitating device discovery. During operation, the system detects, by a computing device, a first message which is broadcast from a source device based on a network communication protocol. The system determines a classification which is a type for the source device based on a MAC address of the source device extracted from the first message. The system generates a second message which indicates the MAC address, an IP address of the source device obtained based on the first message, and the classification. The system sends the second message to a device management system, which causes the device management system to add the source device as a managed device. The system enhances device discovery by eliminating a direct scan of all devices on a sub-network by the device management system for devices of a same type as the type for the source device.

  • Patent number: 10795169
    Abstract: An illuminator optical system combines, homogenizes, and shapes light spatially and angularly from one or more high power fiber coupled lasers. It may include a multichannel fiber cable, collimation and beam shaping optics, a multiple lens array (e.g., fly's eye lens array), and an objective lens. The multichannel fiber collects the light from the high power fiber coupled lasers and produces an aligned array of one or more optical fibers at the output of the cable. The light output from the cable is collimated and relayed to a multiple lens array that spatially divides and shapes the light into an array of beams. The objective lens homogenizes the light by collimating and overlapping the beams into a uniform top hat irradiance distribution in at least one dimension, resulting in the illumination pattern having the required spatial size and desired angular distribution at the illumination plane.
