  • Publication number: 20190260335
    Abstract: Radio frequency (RF) filters configured to filter undesired signal components (e.g., noise and harmonics) from RF signals are disclosed. In one embodiment, an RF filter includes a first inductor coil having a first winding and a second inductor coil having a second winding and a third winding. The second winding of the second inductor coil is configured to have a first mutual magnetic coupling with the first winding, while the third winding of the second inductor coil is configured to have a second mutual magnetic coupling with the first winding. The second winding is connected to the third winding such that the first mutual magnetic coupling and the second mutual magnetic coupling are in opposition. In this manner, the first inductor coil and the second inductor coil may be provided in a compact arrangement while providing weak mutual magnetic coupling between the first inductor coil and the second inductor coil.

  • Publication number: 20190242941
    Abstract: The present disclosure describes methods and apparatuses for testing an integrated circuit. In some aspects, a test engine of a system-on-chip (SoC) receives a test trigger from an external test port of a multi-chip module. The multi-chip module includes the SoC and integrated circuitry. Responsive to receiving the test trigger, the test engine initiates execution of a test associated with the integrated circuitry. The test engine also generates test data associated with the test and provides the test data at the external test port of the MCM. In this manner, internal tests can be executed within the multi-chip module. In other aspects, the SoC and the integrated circuitry are not packaged together. The test engine can receive the test trigger from a test port of the SoC and initiate execution of the test. In this way, the SoC may act as a test instrument for the integrated circuitry.

  • Publication number: 20190172297
    Abstract: A system and method for creating a mixed consumable item may include displaying a first set of selectable indicia on a touchscreen, where the indicia may be (i) indicative of respective consumable ingredients and (ii) distinctly positioned relative to one another. A swype gesture may be received from a user via the touchscreen that forms a path extending between a first position and a second position that touches or passes close to multiple selectable indicia. From the first set of consumable ingredients, a plurality of combinations of consumable ingredients most likely to have been intended to be selected by the user based on the path of the swype gesture may be predicted. Selectable predicted combinations of consumable ingredients may be displayed on the touchscreen to enable one of the selectable combinations of consumable ingredients to be selected by the user for mixing by a dispenser of consumable items.

  • Publication number: 20190162268
    Abstract: A vibration isolation device includes flexures and a multi-part mounting interface for coupling a frame that supports equipment to a structure. The flexures may include three pairs of flexures that allow movement in three orthogonal directions, to allow compliance and/or damp vibrations in the three directions. The flexures may surround the multi-part mounting interface, the parts of which are configured to move relative to one another. One of the parts of the mounting interfaces passes through another part of the mounting interface, such as in one or more holes in one of the interfaces. The device allows equipment mounted on the frame to be isolated from some or all of vibrations produced at the structure. In an example embodiment the vibration isolation system is used in mounting an optical sensor or device to an aircraft.
