International Classification:

H04B 169

US Classification:

375130, 375135, 370242

Abstract:

A discrete multitone stacked-carrier spread spectrum communication method is based on frequency domain spreading including multiplication of a baseband signal by a set of superimposed, or stacked, complex sinusoid carrier waves. In a preferred embodiment, the spreading involves energizing the bins of a large Fast Fourier transform (FFT). This provides a considerable savings in computational complexity for moderate output FFT sizes. Point-to-multipoint and multipoint-to-multipoint (nodeless) network topologies are possible. A code-nulling method is included for interference cancellation and enhanced signal separation by exploiting the spectral diversity of the various sources. The basic method may be extended to include multielement antenna array nulling methods for interference cancellation and enhanced signal separation using spatial separation. Such methods permit directive and retrodirective transmission systems that adapt or can be adapted to the radio environment. Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms.

Such systems are compatible with bandwidth-on-demand and higher-order modulation formats and use advanced adaptation algorithms. In a specific embodiment the spectral and spatial components of the adaptive weights are calculated in a unified operation based on the mathematical analogy between the spectral and spatial descriptions of the airlink.

International Classification:

G08B 1/08

US Classification:

34053913, 340670

Abstract:

A system and method for monitoring the location of a tracking device are disclosed. An example method includes defining location criteria, associating the location criteria with a user, associating the tracking device with the user, comparing location data generated by the tracking device to the location criteria, and transmitting notification to said user if the location data satisfies the location criteria. An example system includes a tracking device interface for communicating with a tracking device, a network interface for communicating with a user, a processing unit for processing data and code, and memory for storing the data and the code, the data and the code together including data associating the tracking device with the user, location criteria associated with the user, and a monitoring routine operative to transmit notification to the user if location data generated by the tracking device satisfies the location criteria. A graphical user interface and implementing data structures are also disclosed.

Inventors:

David Ryan - Los Angeles CA

International Classification:

H02J 700

US Classification:

320 5

Abstract:

A generator and rechargeable battery system for use with pedal powered vehicles, such as bicycles, and where either the generator or battery can intermittently power a load such as a lighting system of the vehicle in one mode of operation, and in which the generator can recharge the battery in another mode of operation. A simple selection switch which is manually operable by the operator of the vehicle enables selection between powering of the load or recharging of the battery.

International Classification:

B32B 300
B41M 700

US Classification:

428 351

Abstract:

An article having a surface comprising an olefin polymer is marked with indicia using an ink comprising a binder capable of substantially complete cure at a temperature of about 100. degree. to 300. degree. C. for less than about 10 minutes and then heated to cure the binder. The indicia are permanent, e. g. are resistant to being rubbed off and are solvent resistant. Heat-recoverable marker sleeves having such permanent indicia are particularly useful for marking wires, e. g. in aircraft harnessing.

International Classification:

A63B 2106

US Classification:

272117

Abstract:

A portable exercising device of simplified design and construction which enables a user to perform a number of different types of exercises. An upright frame or scaffold is provided. A cage or frame for supporting weights is positionable between uprights at the sides of the frame or scaffold. A system of pulleys and lines is provided with detachable hand grips or a bar at the ends of the lines so that a user in various positions holding the hand grips or bar can pull on the lines to raise and lower the cage holding the weights. The user may work between the uprights at the sides of the frame to perform uplifting exercises using barbells and the like. The system of pulleys includes pulley blocks and pulleys at the lower part of the frame and pulley blocks and pulleys at the upper part, the lower ones being swivel mounted and the upper ones being hinged. Alternatively, the lines can pass or not pass over the lower pulleys, the device thereby accommodating many different manners or modes of utilization.
