  • Patent number: 10578476
    Abstract: A three dimensional (3D) printing system includes an ink cartridge providing ink to a printhead and a controller. The ink cartridge also includes a flag material and a sensor component. The ink has a low dielectric constant and defines an upper surface having a vertical position defining an ink level. The flag material has a high dielectric constant and is disposed upon the upper surface of the ink. The sensor component includes a vertical arrangement of electrodes proximate to the ink. The controller is coupled to the sensor electrodes and is configured to: (1) scan sensor electrodes to determine a capacitance between adjacent pairs of electrodes, (2) identify at least one pair of electrodes having a peak capacitance value relative to capacitance values of remaining pairs of electrodes, and (3) estimate the ink level based upon the identification.

  • Publication number: 20190393469
    Abstract: The discharge performance of a primary, bobbin-style electrochemical cell is improved by incorporating a separator formed from a continuous separator sheet defining a two-layer cylindrical sidewall and a closed bottom end between the included electrochemical cell cathode and anode. A first layer of the cylindrical separator is formed by rolling a first end of a continuous separator sheet into a cylinder having a central axis parallel with a longitudinal axis of the continuous separator sheet, and then rolling a second end of the continuous separator sheet around the exterior of the first cylindrical layer to form a second cylindrical layer. The closed bottom end is formed by a portion of the continuous separator sheet located between the rolled portion of the first end and the rolled portion of the second end.

  • Publication number: 20190389412
    Abstract: A trim component, such as a grill of a vehicle, includes a substrate having a 3-dimensional shape and defining a disrupted reflective surface including a plurality of facets over a curved surface. Each of the facets is configured to reflect an incident light beam in a common direction, for example, toward a given target. A reflective coating, such as a chrome plating layer, overlies the disrupted reflective surface. The facets may have similar shapes and/or be arranged in a repeating pattern, but with one or more irregular features. The sizes, shapes, and/or orientation direction of the facets may varying in a gradient based on the curvature of the curved surface. The trim component also includes a light source to illuminate the disrupted reflective surface. The light source may be hidden so it is not directly visible to a viewer, but instead is reflected by the disrupted reflective surface.

  • Publication number: 20190345507
    Abstract: The invention provides methods and compositions for identifying transgenic seed that contain a transgene of interest, but lack a marker gene. Use of an identification sequence that results in a detectable phenotype increases the efficiency of screening for seed and plants in which transgene sequences not linked to a gene of interest have segregated from the sequence encoding a gene of interest.

  • Patent number: 10477619
    Abstract: A firearm includes one or more rails to which accessories may be mounted. The rails provide a communication path over which data may be transferred between the accessories and a processor located in the rails or in the firearm. The processor may cause the data to be sent to another location and may receive other data from other locations to provide a network of intercommunicating firearms that may deployed in a battlefield environment.

  • Publication number: 20190335142
    Abstract: A secure teleconference with a patient treatment room may be initiated by receiving, at a central facility, a request for a conference from a clinician application, and then identifying a virtual meeting room and sending an identifier for a conference to the treatment room. The conference is then be established by receiving a call at the central facility from the treatment room, where the call identifies the conference. The central facility then joins the treatment room and the clinician application to the virtual meeting room. Teleconferences may thus be established without reference to sensitive patient information. For security, no incoming conferencing calls may be made to the treatment room directly, and virtual meeting rooms may be eliminated after single use. A call may further be initiated by receiving a request from the treatment room, e.g., which is processed by the central facility to alert one or more clinicians.

  • Publication number: 20190331978
    Abstract: Onboard EC window controllers are described. The controllers are configured in close proximity to the EC window, for example, within the IGU. The controller may be part of a window assembly, which includes an IGU having one or more EC panes, and thus does not have to be matched with the EC window, and installed, in the field. The window controllers described herein have a number of advantages because they are matched to the IGU containing one or more EC devices and their proximity to the EC panes of the window overcomes a number of problems associated with conventional controller configurations.

  • Patent number: 10428692
    Abstract: A fairing assembly is provided which is located between a frame hub and an engine casing. The assembly provides for use of a metallic structure in combination with a light weight low alpha material in order to improve engine efficiency and performance. Relative growth between the dissimilar materials is compensated for by a flexible bracket which provides biasing force on one of the assembly components in a cold engine condition as well as allowing for growth at the high temperature operating conditions of the engine.
