  • Patent number: 9739796
    Abstract: A portable device for checking wind direction discharges a visible, and optionally scented, vapor (e.g., smoke) stream into the atmosphere in a well-defined reference direction. In some embodiments, the device includes a power source, a vessel having an internal plenum chamber storing a volume of air, a reservoir containing a vaporizable agent e.g., smoke producing fluid), a vaporizing element (e.g., resistance heating device) associated with the vaporizable agent, and a switch. The vessel is deformable to generate an airflow. The switch temporarily connects the power source to the vaporizing element, thereby energizing the vaporizing element to generate vapor. The airflow also carries the vapor into the atmosphere as a visible vapor stream flowing in the reference direction. The reservoir and vaporizing element may be carried in a cartridge (e.g., custom E-Cig component) removably mounted on the device.

  • Publication number: 20150128846
    Abstract: A method and apparatus are disclosed for preventing excavation damage to buried infrastructure. A plurality of excavation-sensing modules is buried near the buried infrastructure. The modules protect buried infrastructure by emitting dense clouds of highly visible gas when the modules are activated by impact with excavation equipment. In most cases the visible gas will be brightly colored and it may also have a strong odor and may produce a loud sound when the module is activated. The dense clouds of highly visible gas, the optional odor and loud sound alert construction crews or other workers that their excavation is nearing a protected underground structure. Once installed, no maintenance or active monitoring is required. In a preferred embodiment of the excavation-sensing module, the dense cloud of highly visible gas is produced by ignition of a smoke grenade within the module.

  • Patent number: 7607402
    Abstract: A shape memory material activated device of the present invention uses a shape memory material activator to create a path through a shell wall of the device. The path through the shell wall may release a substance contained in the shell or allow a substance to enter the shell. The path may be created by fracturing, puncturing, exploding, imploding, peeling, tearing, stretching, separating, debonding, abrading or otherwise opening the shell and, may be permanent or reversible. The substance may be released in one location while the device is stationary or along a path while it is traveling, self-powered by the shape memory material activator. In addition, the substance may be delivered to an object upon contact with its surface. The self powering abilities allow these devices to be used as substance delivery devices as well as actuators, transporters, and energy conversion systems with modular characteristics and growth potential.

  • Patent number: 6843199
    Abstract: An odor-emitting port is provided in a housing member composed mainly of an inorganic material. An odorous material is contained in the housing member, and the odor-emitting port is sealed with a low-melting metal to constitute a heat-sensitive odor-emitting component. In this heat-sensitive odor-emitting component, as soon as the temperature of a heat generation site has reached a predetermined value, the low-melting metal is instantaneously melted down to open the odor-emitting port through which the odorous material contained in the housing member is immediately spread around the odor-emitting component. Therefore, the odor-emitting component is highly sensitive to temperature. Further, since the housing member is formed of an inorganic material, the long-term stability can be improved.

  • Patent number: 5398016
    Abstract: A Vehicle Defense or Security System (VDS) which, once triggered, generates enough smoke to completely engulf the interior of a protected vehicle. The smoke attracts attention to the vehicle and visually impairs would be thieves from seeing valuables inside the vehicle. VDS can be used as an add-on to existing alarms or as a stand-alone defense system. The smoke generated is non-toxic and harmless to humans and the interior of the vehicle. This system provides a unique, effective defense or security system which is silent to eliminate annoying false alarm sirens, horns or the like.

  • Patent number: 5265538
    Abstract: A warning detonator for use on railway tracks or the like is disclosed. The detonator comprises a tube or cylinder (18) having disposed therein at spaced apart locations a length of elastomer (20) and a first explosive component (24, 25). A second explosive component (21) is located therebetween. The second explosive component (21) is also disposed within a cartridge (19) inside the cylinder (18). In use the cylinder (18) is affixed along a length of railway track in a manner whereby the wheel of a passing train progressively compresses the elastomer from its outer end so as to burst an end face (23) of the cartridge (19) and drive the second explosive component (21) into contact with the first explosive component (24, 25) to cause detonation thereof.

  • Patent number: 5186118
    Abstract: A wind gauge includes silica particles dispensed from their container as a floating cloud which is carried along by ambient wind and thus illustrates wind speed and direction. The particulate media may also include a mixture of silica particles and thermoplastic color-pigmented particles, so that the floating cloud is colored and thus more easily visible. The particles may also embody a scent and be used to form a scent trail as they are carried along by the wind and as they gradually settle out of the air.

  • Patent number: 5055822
    Abstract: A scent alarm device which includes a housing and a spray canister of an odorant, such as butyl mercaptan, supported within the housing utilizes a mechanism for intermittently dispensing odorant from the canister upon the occurrence of a predetermined event. The spray canister has a depressible release valve for releasing canister contents upon depression of the valve, and the depressing mechanism is adapted to repeatedly depress the canister release valve in an intermittent fashion. The device may utilize a canister having a height within a range of canister heights, and if desired, the device may be interfaced with a number of other alarm systems, such as a smoke or heat detector or used to alert an individual that household electrical power has been shut off.

  • Patent number: 4773350
    Abstract: A temperature sensor indicates imminent mechanical failure of a device by detecting a sharp rise in temperature of the device above a normal operating temperature range. The sensor is a flexible container filled with a signal fluid and closed by a plug having a melting point which is above the normal operating temperature range of the device. Tube flexure allows it to conform substantially to the shape of a surface on the device being monitored. Flexing the tube changes its internal pressure but has no effect on the plug, which responds only to changes in temperature.
