  • Patent number: 12361801
    Abstract: A computer-implemented method and computer-readable medium for alerting emergency personnel. Using a mobile device, a signal is transmitted to a control hub, the control hub in wireless communication with a server. In response, the signal then transmits from the control hub to a designated switch of a light fixture in the user's home, for example, wherein the light fixture is activated into a flashing mode such that a visible, flashing display of light is presentable external to the home of the user to the emergency personnel. Concurrently, the signal from the mobile device then transmits from the control hub to a 911 call center; and, optionally, the signal can be transmitted over the server to a third-party emergency contact.

  • Patent number: 11109547
    Abstract: Disclosed is a growing system that includes a hollow grow tower with planting units configured to hold plants disposed on the tower exterior where the planting units have a passage that extends into the tower interior. The tower also includes a drain port at one end and a water-dispensing nozzle at the other end. The nozzle includes outlet apertures in fluid communication with the interior of the tower where one or more of the nozzle outlet apertures may be square. An enclosure surrounds the tower, and one or more light sources are mounted on the enclosure to direct light towards the tower. The tower and enclosure can be connected to a suspension frame that suspends the entire system off the ground. The system may include a closed-loop irrigation system and a multi-tank cleaning system. System variables, such as water flow, temperature, lighting, and water nutrient level can be computer controlled.

  • Publication number: 20210189751
    Abstract: An apparatus, method and system for water shaping, including for zero edge pools and related systems, comprising either: (a) a unique dam intended and designed to dimensionally occupy the front of a ledge formed in a shell, where it can serve as a mounting location for waterline finish material as well as serving as the foundation and support for a distinctive mounting plate and related parts that serve, in conjunction with the dam element, as a means of support for coping surface materials and otherwise help to define the enclosed trough of the invention; or (b) a spout-shaped water scupper, such as that shown in FIG. 12 is combined with a planar water-baffle, such as is shown in e.g U.S. Pat. Nos. 5,249,744, 4,881,280, and 6,382,520, to produce a spout-shaped scupper with a pleasing sheetfall appearance analogous to that produced by the linear scupper shown in FIG. 11 when combined with such a baffle; or (c) both (a) and (b).

  • Patent number: 7473301
    Abstract: An efficient device for capturing fast moving particles has an adhesive particle shield that includes (i) a mounting panel and (ii) a film that is attached to the mounting panel wherein the outer surface of the film has an adhesive coating disposed thereon to capture particles contacting the outer surface. The shield can be employed to maintain a substantially particle free environment such as in photolithographic systems having critical surfaces, such as wafers, masks, and optics and in the tools used to make these components, that are sensitive to particle contamination. The shield can be portable to be positioned in hard-to-reach areas of a photolithography machine. The adhesive particle shield can incorporate cooling means to attract particles via the thermophoresis effect.

  • Patent number: 6524449
    Abstract: A method and system for producing a thin film with highly uniform (or highly accurate custom graded) thickness on a flat or graded substrate (such as concave or convex optics), by sweeping the substrate across a vapor deposition source with controlled (and generally, time-varying) velocity. In preferred embodiments, the method includes the steps of measuring the source flux distribution (using a test piece that is held stationary while exposed to the source), calculating a set of predicted film thickness profiles, each film thickness profile assuming the measured flux distribution and a different one of a set of sweep velocity modulation recipes, and determining from the predicted film thickness profiles a sweep velocity modulation recipe which is adequate to achieve a predetermined thickness profile.

  • Patent number: 4811738
    Abstract: A cardiac pacemaker circuit for use with a stimulating electrode embedded in a patient's atrium or ventricle and a reference electrode positioned outside the heart or on the same lead within the heart. Stimulus pulses are applied by the circuit across the two electrodes, these stimulus pulses replacing evoked pulses. On termination of each stimulus pulse the amount of charge stored between the two electrodes is monitored and pulses of short duration are applied to the stimulating electrode progressively to reduce this charge over a very short time period to a level at which the intrinsic pulses of the evoked heart response can be monitored. The evoked heart response can then be used for diagnosis while the pacemaker circuit is in operation. If the stored charge was not reduced quickly then the charge would mask the intrinsic pulse and the pacemaker would have to be switched off before the intrinsic pulses could be monitored for diagnosis.
