摘要:
An airfoil that comprises a chamber having a forward-facing chamber opening may result in increased lift and decreased drag relative to a standard airfoil having deployed flaps, for example on an airplane wing. In embodiments, the chamber opening is located on or near the pressure surface of the airfoil. The airfoil chamber may enhance the lift-generating ability of the airfoil due to increased pressure at the pressure surface.

An intelligent auxiliary power supply system for supplying power to a load such as a furnace or air handler using a rechargeable power source. An intelligent controller determines appropriate periods for switching to auxiliary power, thus allowing the user to realize increased energy related cost savings. A plurality of sensors including a current transducer, an indoor and outdoor temperature sensor, and a clock transmit information to the intelligent controller. Implementing user configured algorithms, the intelligent controller continuously compares information transmitted from said sensors and said load, to information inputted by the user via an electronic device to determine the appropriate power configuration. A remote electronic device may also be connected to the system, allowing the user to control the system while not in close proximity to said system and also allowing the user's energy provider to send requests to switch to auxiliary power.

A method for controlling fossil fuel fired heating systems according to an improved adaptive cyclical control method when operating on backup (auxiliary DC) electrical power. Battery life is prolonged when used in conjunction with such improved method. Operating characteristics of the heating equipment and home or building being heated are monitored and stored in electronic memory during normal periods of operation when grid power is available. These characteristics are used to create control algorithms that are in turn specific to the system, as defined by the heating equipment and conditioned space. When the grid power is lost the control algorithms select the optimal heating mode, determine optimal cycle duration, and estimate the time to exhaustion of the remaining backup power.Operation is divided into sequential modes. When a prolonged low voltage period is detected, the backup power control initiates a short-term preliminary energy conservation mode. As the outage persists, the control transitions to intermediate and long-term energy conservation modes until the backup power is exhausted or grid power is restored.

The invention relates to a hairdressing method consisting in increasing the apparent volume of a head of hair and simultaneously setting it in this state of swelling by means of an aerosol generator. To do so, the aerosol is shaken with a mass flow of between 0.5 and 4.0 g/s at 20.degree. C., ensuring an atomization which provides a thrust of between 6,500 and 40,000 dynes at 20.degree. C. on a disc having a diameter of 160 mm, placed 150 mm from the dispensing head.

摘要:
An apparatus and system for monitoring and managing traffic flow. The system includes a plurality of remote sensor devices arranged in a plurality of vehicles, a plurality of remote communication hub devices operatively arranged along one or more roadways and in communication with the plurality of remote sensor devices, a central server, a network interface in communication with the central server and the plurality of remote communication hub devices over a network, and a shared database in communication with the central server. The central server is configured to receive traffic data from the plurality of remote sensor devices over the network, update traffic data in the shared database, periodically calculate an optimal traffic flow for one or more of vehicles traveling along the one or more roadways based on the updated traffic data, and transmit timing adjustments over the network to one or more traffic light intersections based on the optimal traffic flow calculations. The network interface is configured to send and receive traffic data. The traffic data includes vehicle location information and network traffic congestion information.
摘要:
A portable air pump apparatus and method that includes an elongated elongated cylinder portion having a first air channel for transporting compressed air, and an air discharge portion having a connection head, a finger or thumb grip portion, a rotatable thumb-lock lever, and a second air channel extending vertically therethrough the air discharge portion and engagable with an inflation valve of an inflatable object. The second air channel is in communication with the first air channel of the elongated cylinder portion. The rotatable thumb-lock may be rotated within a predetermined range of movement defined substantially by a non-engaged position and an engaged position. The portable air pump is configured such that a user may grasp the air discharge portion with a single hand using the finger or thumb grip portion to place the connection head over an inflation valve of the inflatable object and to use one or more fingers to move the rotatable thumb-lock lever from the non-engaged position to the engaged position, thereby enabling air to flow into the inflatable object from the air pump apparatus without significant air loss.
