  • Publication number: 20240026732
    Abstract: A door system includes a doorframe having opposing vertical jambs, a door pivotably coupled to the doorframe, a threshold extending between the opposing vertical jambs and providing an upper surface that defines a valley, and a dam removably mountable to the threshold at the valley. A valley seal interposes the dam and the threshold at the valley when the dam is mounted to the threshold and thereby generates a sealed interface between the dam and the threshold.

  • Patent number: 11747379
    Abstract: In an embodiment, an apparatus is disclosed that comprises a plurality of resistors arranged as a reverse bridge and configured to convert an input voltage to a scaled output voltage. The scaled output voltage is scaled to a target format based at least in part on a range of the input voltage and a fixed value of the plurality of resistors. The input voltage is generated based at least in part on at least one signal generated by a sensor based at least in part on a measurement of a property of a measurement target. At least one of the plurality of resistors has a resistance value of R and at least another of the plurality of resistors has a resistance value of R plus or minus ?R.

  • Publication number: 20230251667
    Abstract: Improved security checkpoint includes a security scanning system having multiple personal item intake locations, a security scanner, multiple personal item retrieval locations, and a plurality of computer-controlled vehicles for transporting personal items between the personal item intake locations, the security scanner, and the personal item retrieval locations. Personal items are placed into a tote by an individual, and the computer-controlled vehicles collect the totes containing the personal items, transport the tote to an available security scanner, deposit the tote at the security scanner, and then transport the tote either to a retrieval location or secondary screening location after the personal item has been screened.

  • Publication number: 20230078998
    Abstract: A door assembly includes a door having opposing first and second surfaces and a hole defined in the door and extending between the first and second surfaces, a cylinder lock mounted to the second surface at the hole, and a cylinder dry lock assembly mounted to the door at the hole adjacent the first surface. The cylinder dry lock assembly including a main body that defines a central orifice, a low-friction member received within the central orifice, and an actuation mechanism extending from the low-friction member and engageable with the cylinder lock. Actuating the cylinder lock rotates the actuation mechanism, and the cylinder dry lock assembly generates a sealed interface at the hole that prevents water from migrating between the first and second surfaces at the hole.

  • Patent number: 11532216
    Abstract: The present disclosure concerns a warning device comprising a warning body having a longitudinal axis and comprising a light-emitting assembly; and a collapsible stand configurable in a compacted configuration and in a warning configuration in which the light-emitting assembly is at least partially visible. The collapsible stand comprises a handle sleeve mounted to and slidable along the warning body and legs pivotably mounted to the handle sleeve, the legs being juxtaposed against the warning body when the collapsible stand is in the compacted configuration to cover the warning body and the legs extending outwardly and downwardly when the collapsible stand is in the warning configuration, the collapsible stand being configurable between the compacted configuration and the warning configuration by sliding the handle sleeve along the warning body. The disclosure also concerns a warning assembly comprising such a warning device and a method of emitting a warning light signal.

  • Patent number: 11226259
    Abstract: A test fixture for securing a test article is disclosed. The test fixture includes a frame, an upper grip, at least one heat shield, a cooling assembly, and insulation. The frame defines an upper portion and a lower portion. The lower portion of the frame is releasably mounted to a vibration device. The upper grip is connected to the upper portion of the frame and the lower grip is connected to the lower portion of the frame. The heat shield is positioned to insulate at least one of the upper grip and the lower grip. The upper grip is configured to secure an upper portion of the test article along an upper interface. The lower grip is configured to secure a lower portion of the test article along a lower interface. The cooling assembly transports a cooling medium across at least one of the upper interface and the lower interface.

  • Patent number: 11056009
    Abstract: Techniques are described for the exchange of control signals between a controlled unmanned aircraft (i.e. drone) and a ground control station and for the transmission of communication signals, such as video, from the drone to the ground control station so that the signals are more difficult to intercept or jam. The video signal transmitted from the drone can be an analog RF signal employing one or more of video “scrambling”, RF signal inversion, hopping, usage of a wide frequency range and other techniques. To secure the control signals between the drone and the ground control station, techniques can include hopping, encryption and use of a wide frequency range.
