Abstract: The wheeled personal transportation device includes a frame member having opposed front and rear ends having front and rear wheels rotatably mounted thereto. An air cushion has upper and lower ends, the lower end being supported by the frame member. A foot platform is mounted on the upper end of the air cushion, the foot platform being adapted for supporting a foot of a user. A pneumatic motor is mounted on the front end of the frame member and is in communication with the front wheel for selectively driving rotation thereof. The pneumatic motor is in fluid communication with the air cushion such that compression of the air cushion by the user's foot drives the pneumatic motor to drive rotation of the front wheel. A pneumatic brake is further in communication with the rear wheel for selective braking thereof. Alternatively, the front wheel may be powered mechanically by spring-biased gears.

Abstract: The system and method for securing scalar multiplication against simple power attacks (SPAs) delays required point additions in elliptic curve cryptosystem scalar multiplication. A buffer is used to store the points that will be added later until the buffer is full or the last bit of a multiplier k is inspected, Then, the stored points in the buffer are added to the accumulation point. The same procedure is repeated whenever the buffer is full again. This makes the power trace appears as a repeated sequence of consecutive point doubling followed by consecutive point additions. This makes it very difficult for an attacker to know the exact value of the inspected bit during the scalar multiplication process.

Abstract: The differential ultra-wideband indoor positioning method provides differential positioning to increase the accuracy of ultra-wideband (UWB) based indoor position estimation. Knowledge about common errors can be learned by employment of a reference source, where the difference between its known and estimated position (differential operation in solution domain), or the difference between the known and measured ranges (differential operation in measurement domain), provides invaluable information to be utilized in reducing errors in estimating the position of the target source. Differential operation accuracy reaches far beyond the accuracy of the non-differential setting.

Abstract: The method to obtain accurate vertical component estimates in 3D positioning provides a closed-form least-squares solution based on time-difference of arrival (TDOA) measurements for the three-dimensional source location problem. The method provides an extension of an existing closed-form algorithm. The method utilizes the full set of the available TDOA measurements to increase the number of nuisance parameters. These nuisance parameters are range estimates from the source to the sensors, which the method uses for delivering accurate estimates of the vertical component of the source's location, even when quasi-coplanar sensors are employed.

Abstract: The cut stone construction and masonry method is a wall construction technique using the Flemish bond pattern and utilizing natural stone cut in blocks. The technique employs only vertically oriented semi-dry mortar layers between the stones. No horizontal mortar layers are used in the construction, except at the foundation level. Use is made of the dry-stacking, horizontal surface bonding techniques developed by the ancient Egyptians.

Abstract: The method of treating venomous bites, such as those from snakes and scorpions, involves treatment by the administration of a therapeutically effective amount of an aqueous extract of the fruit of Juniperus phoenicea, or pharmaceutically acceptable salts thereof. In order to treat the bites of venomous snakes, scorpions and the like, approximately 500 ml of an extract of the fruit of Juniperus phoenicea, or pharmaceutically acceptable salts thereof, is orally administered to a patient three times daily for a period of five days. In order to make the antivenin, formed as an extract of the fruit of Juniperus phoenicea, a quantity of the fruit of Juniperus phoenicea is ground, and then mixed with water. The mixture is then filtered to separate out the extract of Juniperus phoenicea, the filtrate forming the antivenin.

Abstract: The solar, water desalination system includes a desalination chamber where fine water droplets are injected upward by an air atomizer towards an air-cooled condenser. Hot saline water is ejected vertically upward to double the contact time between the droplets and the surrounding air. The air is preheated by solar energy in parallel with an auxiliary heater to prevent lowering of the droplet temperature. Pumped air functions as a condensation media and to pull the salt water into the atomizer. This arrangement improves the heat and mass transfer inside the desalination chamber.

Abstract: The environmental test chamber for wireless sensor networks includes a structural enclosure having peripheral walls. A dynamic topology builder is a hanging mechanism disposed in a ceiling portion of the structure and is used to suspend the wireless devices below the ceiling portion via a cable. A weather conditioning machine simulating environmental conditions is disposed in at least one of peripheral walls. A controller sends commands to control the suspension height of the wireless units and to control environmental parameters of the weather conditioning machine. This allows the test chamber to test the communication and networking aspects of the wireless sensor network devices in different environmental conditions, such as sand storms and different temperatures, and humidity levels, within a 3-D topology specified by the controller.

Abstract: The system and method for securing scalar multiplication against differential power attacks (DPAs) delays required point additions in elliptic curve cryptosystem scalar multiplication. A buffer is used to store the points that will be added later in a random manner. Then, a randomly selected one of the stored points in the buffer is added to the accumulation point, or several randomly selected points are added consecutively. This makes the power trace appear as a repeated sequence of consecutive point doubling followed by consecutive point additions, which makes it very difficult for an attacker to know the exact value of the inspected bit during the scalar multiplication process.

Abstract: The catalytic converter for confined areas is installed with a vehicular tunnel, parking garage, or other confined area subject to motor vehicle operation therein. The converter catalyzes internal combustion engine exhaust by-products by selective catalytic reduction. The heat required for the catalytic reaction is provided by an electric heater installed with the converter, the converter being thermally insulated to retain the heat. The carbon dioxide and water vapor resulting from the catalytic reactions are gathered by the same fan or pump and the water vapor condensed to liquid form, and distributed to vegetation external to and adjacent to the tunnel or enclosure.

Abstract: The evaporative cooler and pad operates on the principle of cooling the air by evaporation of water passing through one or more evaporator pads in the cooler. The evaporation of water cools the air as it is drawn through the cooler by an internal fan. The pads of the evaporative cooler and pad are formed of luffa sponge fibers. The cooler may include a device for dispensing antimicrobial and/or antifungal agents into the water reservoir of the cooler. Alternatively, the pads may be pretreated with antimicrobial and/or antifungal agents. A cooling fan is provided in the interior of the cooler to blow cooled, humidified air over the surface of the water in the reservoir before the water is passed through the evaporator pads, thereby increasing the cooling efficiency of the system.
