  • Publication number: 20250198107
    Abstract: The field of the invention is surface albedo modification which applies to modifying the surface of areas of the earth to increase albedo. The invention relates to a means of preserving and restoring glaciers that are shrinking or receding due to climate change. Global warming has led to widespread shrinking of the cryosphere, with mass loss from ice sheets and glaciers. The shrinking of the cryosphere is accelerated by the ice-albedo feedback loop. The invention is a method of modifying the surface of a glacier by covering portions of it with highly reflective granules to increase albedo and reduce the melting of the glacier due to solar radiation. The invention may be used to preserve or restore glaciers and ice sheets that are melting due to climate change.

  • Publication number: 20140074086
    Abstract: A surgical operating room table pad that functions in multiple capacities such as a dielectric capacitor for grounding the electro-surgical current from cautery device and heating the patient contact surface for the maintenance of patient normal-thermia. The “capacitor/dielectric” is designed to allow the electrosurgical current introduced to the patient to return back to the electrosurgical generator for patient and surgical staff safety. The temperature of the patient's body is constantly measured by a series of RTD Thermister sensors and a resistive device is utilized for thermal input.

  • Patent number: 7176419
    Abstract: A heating pad system useable in one embodiment for warming a person on a support structure. In this embodiment, the heating pad system comprises an upper foam pad, a lower foam pad, and a thermal-electric heating element sandwiched between the upper and lower foam pads. A form-fitting waterproof cover encloses at least a portion of the upper and lower foam pads and the thermal-electric heating element. In one aspect of this embodiment, the heating pad system includes a power unit for providing electrical power to the thermal-electric heating element, the power unit including a control panel having at least one temperature selector, the temperature selector for selecting at least one heating pad temperature.

  • Publication number: 20070012259
    Abstract: A cellulose particulate provides a safe and aesthetic bedding or litter material for small animals. The material may be provided in bright white or in vivid colors. Brightness and color clarity are maintained during manufacture by apparatus having non-corroding surfaces. The material offers aesthetic elements in small animal cages or enclosures. The material may be formed into particles having no sharp edges or corners. This provides a safe and comfortable bedding or litter material for small animals.

  • Patent number: 7114619
    Abstract: A medicine container includes a child-resistant closure with a tamper-evident feature. The closure includes a plug adapted to be fixed to the container adjacent the open end. The plug has an access opening for enabling removal of material from the container through the open end of the container. A slide is supported on the plug for sliding movement in a first direction relative to the plug between a closed position in which the slide covers the access opening and an open position in which the access opening is uncovered. A child-resistant feature is interposed between the plug and the slide. The closure also includes a tamper-evident feature that permanently indicates breaking of the original seal of the container. The container may have a rectangular configuration including at least one surface large enough for a mailing address label; and a sealable window mailer envelope for receiving the medicine container.

  • Patent number: 5928971
    Abstract: A face cloth for a thermal barrier of a firefighter's garment made from a fabric woven from fire resistant yarns. The yarns are woven into a twill pattern with, preferably, filament yarns in the filling direction and spun yarns in the warp direction and a finish is applied to the fabric. The finish is accepted by the fabric and renders the face cloth both wickable and hook-and-loop compatible. The face cloth has a smooth and slick surface and is wickable and hook-and-loop fastener compatible.
