  • Publication number: 20240085373
    Abstract: A method of operating a differential mobility spectrometer (DMS) includes providing a heater disposed proximate a ceramic body of a DMS cell. A first control voltage is applied to the heater. A first threshold is detected by a first sensor disposed within a curtain plate that substantially surrounds the DMS cell. A second control voltage is applied to the heater based at least in part on the detected first threshold. During application of the second control voltage, a mass spectrometry analysis of a gas within the DMS cell is performed.

  • Patent number: 11814895
    Abstract: A security panel mounting system having: a mounting unit configured to attach to a mounting surface; a securing unit configured to attach to the mounting unit to form a base fixture; a shock gasket configured to nest within the base fixture, wherein the shock gasket is configured to secure a security panel within the base fixture; and a cover configured to engage with the base fixture. A center mullion may be implemented to allow multiple security panels to be mounted within the mounting surface. One advantage is that the security panel mounting system may allow for the utilization of security panels within any window or door to enhance security. Another advantage is that the shock gasket may allow for the expansion and contraction of the security panels, as a result of changes in ambient conditions, to occur without resulting in bowing or deformation of the security panel.

  • Publication number: 20230151678
    Abstract: A security panel mounting system having a mounting unit configured to attach to a mounting surface; a securing unit configured to engage with the mounting unit wherein the engagement of the securing unit with the mounting unit forms a base fixture; a first narrow gasket and a second narrow gasket, each narrow gasket having: a narrow gasket body; a T-shaped narrow gasket handle attached to the narrow gasket body; and a gasket hollow nested within the narrow gasket body; wherein each narrow gasket handle is configured to engage with a corresponding structure within the base fixture to secure a security panel within the base fixture; and a cover configured to engage with the base fixture. An advantage is that the hollow within each narrow gasket may allow an impact to the panel to be responded more flexibly, reducing the likelihood of the mounting system being damaged from the impact.

  • Patent number: 11585150
    Abstract: An insulated glass unit having: an outer lite, an inner lite, and a shock absorbing spacer bar disposed between perimeter portions of the inner and outer lite, forming a cavity, the spacer bar having: an inner housing with a plurality of desiccant ports disposed between an internal desiccant chamber and the cavity; a desiccant encased within the desiccant chamber; a flexible outer housing in which the inner housing is nested; and a perimeter guard disposed on the outer surface of the spacer bar, said perimeter guard being configured to attach the spacer bar to each lite. The spacer bar is configured to be highly crush resistant, thus preventing the either lite from being dislodged during a forced entry attempt. The desiccant ports expose the desiccant to the cavity for humidity maintenance within said cavity. An additional lite and spacer bar may be implemented to form a three lite IGU.
