  • Patent number: 12583015
    Abstract: The presently disclosed methods provide for preparing a stable hydrophobic self-assembled monolayer (SAM) coating, that includes preparing a SAM solution by combining a SAM compound with an initial solvent and an additional solvent and mixing, in a sealed container, the SAM solution at a first fixed temperature at a constant rotational speed for a first fixed time interval. The SAM coating is then prepared by treating a substrate to achieve pristine state, and heating the substrate at a second fixed temperature for a second fixed time interval. Then within a sealed container, immersing the substrate in the SAM solution for a third fixed time interval. Following the completion of the third fixed time interval, the substrate is removed from the sealed container and treated with the initial solvent and the additional solvent to remove excess SAM material, and heated at a third fixed temperature.

  • Patent number: 11609286
    Abstract: A monitoring system for use in combination with, in particular a ferromagnetic, detection system of the kind that generates a warning signal to indicate a detection event when the detection system detects movement of a door protecting an entrance to a protected area. The monitoring system may include a processor configured to present information to a user to alert the user when the warning signal indicates a detection event; and a user interface configured to accept a user input in response to the presentation of the detection event that generates a user generated signal indicative of whether the detection event was the result of an unintentional action or an intentional action. The processor may be configured to automatically store data relating to the detection event in a memory unit when the user generated signals indicates that the detection event was the result of an unintentional action.

  • Publication number: 20190177233
    Abstract: This invention relates generally to an article that includes a base substrate, an intermediate layer including at least one element or compound selected from titanium, chromium, indium, zirconium, tungsten, and titanium nitride on the base substrate, and a hydrophobic coating on the base substrate, wherein the hydrophobic coating includes a rare earth element material (e.g., a rare earth oxide, a rare earth carbide, a rare earth nitride, a rare earth fluoride, and/or a rare earth boride). An exposed surface of the hydrophobic coating has a dynamic contact angle with water of at least about 90 degrees. A method of manufacturing the article includes providing the base substrate and forming an intermediate layer coating on the base substrate (e.g., through sintering or sputtering) and then forming a hydrophobic coating on the intermediate layer (e.g., through sintering or sputtering).

  • Patent number: 6604195
    Abstract: A reset pin of a non-volatile read/write memory, which stores boot code, is provided with a reset signal in response to a system reset output by a watchdog timer or other external circuitry. The reset signal causes the non-volatile read/write memory to be placed into read mode. Accordingly, even when a system reset occurs while the non-volatile read/write memory is in write mode, a hang state can be avoided since the memory will be reset to read mode before attempting to read boot code for a reboot operation.
