  • Publication number: 20190377838
    Abstract: A computer-implemented method designs a distributed heterogeneous computing and control system, including both an application and a hardware context and configuring the application in the hardware context. The method is implemented by design software instructions executing in a computer node, associated with an interactive display, to establish an interactive environment utilizing computer processes. The computer processes provide access in the interactive environment to a set of functional modules and a set of primitive modules. The computer processes receive the interactive environment a selection of desired ones of the functional modules and the primitive modules and order them in a manner to characterize the distributed computing and control system as a schematic of a set of devices. The computer processes parse the schematic to produce a set of sub-schematics that each correspond to a distinct device in a set of devices in the distributed computing and control system.

  • Patent number: 10407194
    Abstract: A method and system involves vacuum sealing a semi-enclosure at room temperature without requiring mechanical actions within the vacuum chamber. The semi-enclosure has an inlet channel that extends inwardly into the vacuum chamber from an exterior opening (entryway) into the semi-enclosure. An uncured entryway vacuum sealant is provided at the entryway for the semi-enclosure. A vacuum is established in the vacuum chamber until the vacuum pressure reaches a desired vacuum pressure that causes the uncured entryway sealant to be provided to the entryway for the semi-enclosure. The uncured entryway vacuum sealant is cured under vacuum pressure in the semi-enclosure in the vacuum chamber.

  • Patent number: 10073092
    Abstract: A lateral flow assay device that is defined by multiple loading zones, wherein a sample pad is located before and upstream from a conjugate pad and another sample pad is located after and downstream from the conjugate pad. This configuration allows for increased sensitivity for detecting an analyte in a specimen. The device may employ multiple collection pads or a single collection pad and the collection pads may be engaged with the sample pads in several manners, including but not limited to, pressing down on a cassette with collection pads onto a cassette with the test strips, or by sliding the collection pads along the cassette with the test strips and sample pads.

  • Patent number: 10027281
    Abstract: A system includes a circular oscillator suspended by a flexible support structure to a support frame, a drive mechanism configured to induce the circular oscillator into a two-dimensional drive oscillation, where the drive oscillation is modified responsive to a sense oscillation of the circular oscillator caused by an angular rotation of the support frame and the circular oscillator, and a plurality of digital proximity switches disposed around a perimeter of the circular oscillator. During the modified drive oscillation a plurality of the digital proximity switches are configured to switch between an open state and a closed state and generate a time and position output to allow for a determination of each of a plurality of variable oscillation parameters for each oscillation of the modified drive oscillation.

  • Patent number: 9995781
    Abstract: A ground fault detection system based on capacitive sensing suitable for use in detecting a ground fault condition in electronic equipment (such as a PCBA) with a circuit ground electrically isolated from an isolation ground (such as chassis ground). The capacitive sensing system includes a capacitive sensor capacitively coupled to the system isolation ground, and a capacitance/data converter that captures sensor capacitance measurements for conversion to sensor data representative of a ground short. In one embodiment, the capacitive sensor includes a sensor electrode capacitively coupled to the system isolation ground by one of projected capacitance and a floating capacitor (such as 33 pf), and the CDC unit further includes sensor excitation circuitry configured to drive the sensor electrode, such that a sensor capacitance (projected or floating capacitance) is representative of an electrical condition of the system isolation ground.

  • Patent number: 9977046
    Abstract: A device includes two electrically isolated metalized posts attached in close proximity to each other on a bendable substrate. When the bendable substrate bends concavely with respect to the surface onto which the posts are mounted, the distance between the tops of the two posts decreases. At a fixed bending curvature, the two posts will meet and complete an electrical circuit. The posts comprise a flexible material so that the meeting of the posts has minimal effect on the spring constant or damping coefficient of the harmonic oscillation.

  • Patent number: 9667948
    Abstract: A method and system for providing a three-dimensional (3D) display. A variable length z-axis is added to each of plural (x,y) cells in a two-dimensional (2D) Cartesian plane creating plural three-dimensional (3D) cells each with a x, y and z axis. The z-axis includes a variable length light source for each of the plural x-y cells. The z-axis also includes a space vector including time and space information. A 3rd dimension is created by changing a length of the light source. A 2D image cell at (x, y) is moved along the 3D z-axis (x, y, z?) with viewing angle (?) to create a converted 3D image. An original 2D image adding z-axis with a space vector can be viewed as a 3D image on any network device (e.g., smart phone, tablet, wearable device, TV, etc.) without additional devices such as 3D glasses, 3D set-top boxes, etc.
