  • Patent number: 10299525
    Abstract: Air from a heating or cooling unit stored in a backpack is blown by a fan into an extendable tube and through a delivery tube to deliver heated or cooled air to wearer. The delivery tube can be run into a hat, helmet, or cap to heat or cool the head of the wearer. Alternatively, the delivery tube can bifurcate to create a yoke from which two perforated delivery tubes extend that run over the shoulders of the wearer beneath their clothes to deliver heated or cooled air. The extendable tube allows the wearer to move freely, turning their head side to side or nodding up and down.

  • Patent number: 8336113
    Abstract: An improved welding helmet encloses a welders head and a portion of the neck. The helmet contains a fan, filter and thermoelectric cooling module to provide clean, cool air that reduces welding fume levels below suggested maximums and provides cool air to the welders head and neck area making their body feel cooler. Air exhausted from the helmet is captured and further utilized to significantly improve system efficiency by causing it to be in contact with the hot side heat sink that is a part of the thermoelectric cooling module assembly. The use of an external power source, including readily available welding power, is suggested as one option for supplying system power. An optional configuration is presented where an external container strapped to the welders body is employed containing the fan, air filter and thermoelectric cooling module and is connected to the helmet by cool air intake and exhaust air hoses.

  • Patent number: 8156570
    Abstract: The lack of air flow under body armor, helmets, and thick garments can lead to excessive moisture build up and discomfort on the wearers body due to lack of heat removal and effective evaporation of sweat. By incorporating wick covered heat pipes or thermal conductors with air flow channels in the apparel contact area between the garments, helmets, and body armor the effectiveness air flow cooling and evaporation of sweat can be restored. Humidity or temperature auto-actuated bi-material valves are used to control this air-moisture-heat flow to achieve a controlled comfortable humidity-temperature environment and avoid excessive cooling. Supplementary air pumps, filters, dehydrators, fluid pumps, heating fluids, and cooling fluids may be incorporated to enhance the effectiveness. Biocides and hydrophilic materials are also incorporated on the wick coverings to avoid biological growth and maintain performance to achieve a healthy environment for the wearer.

  • Patent number: 8104094
    Abstract: This invention defines a welding helmet that encloses a welders head on five sides and with an optional skirt covers their neck. The helmet contains a fan, filter and cooling module to provide clean cool air that reduces welding fume levels in the breathing zone below suggested maximums. By providing cool air to the welders head and neck area their whole body will feel cooler. It suggests the use of an external power source to provide the energy required to have a fan of sufficient capacity to draw air thorough a quality filter so potentially hazardous constituents of welding fumes are captured. This externally supplied power allows the required cooling capacity thermal electric cooling modules to be used to significantly lower the ambient air temperature. This helmet allows the welding operator to have sufficient cooling to improve their overall work environment for one of the most objectionable welding issues, excess heat.

    Abstract: Systems and methods for providing an article associated with headgear that keeps the wearer's head both cool and cushioned from the interior harness of the headgear. The article is a system, liner or pad that is inserted into the headgear or coupled to the headgear harness for cooling and comfort, and includes a water absorbent polymer or other material contained within non-impervious pocket partitions attached to a concave disk of mesh fabric. The mesh fabric provides ventilation portions, which allow for the free flow of air and breathing of the wearer's scalp to facilitate the natural evaporation of perspiration. The article provides a cushion to the wearer's scalp from the abrasive effect of the webbing of the headgear harness. As the pocket partitions swell due to absorption of water by the polymer material, the pockets function as gel-like cushions or pads that protect the wearer's scalp. The article is held in place with small straps, Velcro® tabs, or other retention devices.

  • Patent number: 6932150
    Abstract: A heat-dissipation device adopted for a safety helmet which includes a heat-transfer unit that functions as a heat pipe, a heat-dissipation unit connecting to the heat-transfer unit, a vent formed in a front of the heat-dissipation unit that can be closed and opened alternatively by a shutter unit in order to adjust the capacity of heat-dissipation thereof, and a covering unit made of insulative materials and spreading over the heat-dissipation unit. Whereby the heat-transfer unit provides a kind of two-phase flow that is capable of conducting heat rapidly, so as to remove heat gathered in the helmet and improve the comfort level for the wearer.

    Abstract: A method, apparatus, and article of manufacture for performing data mining applications in a relational database management system. An analytic algorithm for clustering is performed by the computer. The analytic algorithm for clustering includes SQL statements performed by the relational database management system for reducing data retrieved from the relational database in bulk, and programmatic iteration for operating on the reduced data to find clusters therein. The analytic algorithm for clustering creates at least one analytic model within the analytic logical data model from data residing in the relational database.

  • Patent number: 6760925
    Abstract: Air-conditioned hardhats cool the wearer's head. A motor and fan are attached to the top of the interior of a hardhat to blow air over a coolant reservoir onto the wearer's head. The coolant reservoir can be filled with coolant. The bottom of the coolant reservoir comprises an atomizer, which allows the coolant to evaporatively cool the wearer's head. The motor is powered by a solar cell and/or a rechargeable battery. The rechargeable battery may be charged by a battery charger that is connected to the solar cell and can be optionally connected to an electrical outlet by a charging cord. A switch allows the user to control whether the motor is powered or not.

  • Patent number: 6463589
    Abstract: A smoke-proof headgear has a headgear body. The headgear body is made of aluminumized oxide fiber cloth. A window is seamed to a predetermined position through a connecting fire-proof wire. The lower side of the window has a filtering piece of a gauze mask and a neck tighter is placed at the inner side of the headgear body. All the components are made of heat-tolerable materials. In use, the user wears the headgear at first; and the filtering piece is used to mask the mouth and nose. A press-able switch adjusts the spanner band to a correct position for preventing smoke from entering into the body so as to protect the head, eyes. and breathing system of the user from being harmed. Moreover, the user breaths through the breathing tube so as not to feel hot and the user may clearly see the situation of the scene of a fire.
