  • Patent number: 10679018
    Abstract: A magnetic tracking apparatus, method, system and computer program product for magnetically encoding pills are provided. A pill feeder includes a first valve controlling an opening of the pill feeder. A chamber is arranged in communication with an outlet of the pill feeder, and a second valve when closed retains the pill within the chamber, and when open communicates with a passageway for the pill to exit the chamber. A microcontroller is configured to control operation of the first valve and the second valve. A magnetic nano-particle applicator deposits bio-compatible nano-magnetic particles in a magnetic pattern onto a surface of the pill within the chamber. A system for detection of the pill includes a wearable patch or article including a magnetic reader to read the magnetic pattern on a coated pill when consumed by the patient.

  • Patent number: 10658182
    Abstract: Small size chip handling and electronic component integration are accomplished using handle fixturing to transfer die or other electronic components from a full area array to a targeted array. Area array dicing of a thinned device wafer on a handle wafer/panel may be followed by selective or non-selective de-bonding of targeted die or electronic components from the handle wafer and optional attachment to a carrier such as a transfer head or tape. Alignment fiducials may facilitate precision alignment of the transfer head or tape to the device wafer and subsequently to the targeted array. Alternatively, the dies or other electronic elements are transferred selectively from either a carrier or the device wafer to the targeted array.

  • Patent number: 10638945
    Abstract: An apparatus includes a substrate mechanically and electrically connected on one side of the substrate to multiple metallic probes in one or more arrays and includes the multiple metallic probes in the one or more arrays. In a method, multiple pits may be formed in an array on a first substrate. The pits have a pyramidal shape. A release layer is formed on the first substrate and covers surfaces of the pits. Probe tips are formed in the pits on the first substrate. The probe tips are formed from rigid conductive material. Multiple pillars are formed from rigid conductive material. The pillars are electrically and mechanically connected to a second substrate and to the probe tips. Release is caused of the probe tips from the first substrate, wherein the pillars and probe tips are connected to the second substrate and together form an array of rigid and conductive probes.
