An ultra wide bandwidth, high speed, spread spectrum communications system uses short wavelets of electromagnetic energy to transmit information through objects such as walls or earth. The communication system uses baseband codes formed from time shifted and inverted wavelets to encode data on a RF signal. Typical wavelet pulse durations are on the order of 100 to 1000 picoseconds with a bandwidth of approximately 8 GHz to 1 GHz, respectively. The combination of short duration wavelets and encoding techniques are used to spread the signal energy over an ultra wide frequency band such that the energy is not concentrated in any particular narrow band (e.g. VHF: 30-300 MHz or UHF: 300-1000 MHz) and is not detected by conventional narrow band receivers so it does not interfere with those communication systems. The use of pulse codes composed of time shifted and inverted wavelets gives the system according to the present invention has a spatial resolution on the order of 1 foot which is sufficient to minimize the negative effects of multipath interference and permit time domain rake processing.

A method of manufacturing monolithic glass reflectors for concentrating sunlight in a solar energy system is disclosed. The method of manufacturing allows large monolithic glass reflectors to be made from float glass in order to realize significant cost savings on the total system cost for a solar energy system. The method of manufacture includes steps of heating a sheet of float glass positioned over a concave mold until the sheet of glass sags and stretches to conform to the shape of the mold. The edges of the dish-shaped glass are rolled for structural stiffening around the periphery. The dish-shaped glass is then silvered to create a dish-shaped mirror that reflects solar radiation to a focus. The surface of the mold that contacts the float glass preferably has a grooved surface profile comprising a plurality of cusps and concave valleys. This grooved profile minimizes the contact area and marring of the specular glass surface, reduces parasitic heat transfer into the mold and increases mold lifetime. The disclosed method of manufacture is capable of high production rates sufficiently fast to accommodate the output of a conventional float glass production line so that monolithic glass reflectors can be produced as quickly as a float glass production can make sheets of float glass to be used in the process.

A plurality of beams of illumination light are emitted from a LIDAR device over a range of angles and scanned about an axis of rotation. The range of angles includes the axis of rotation. Intermediate electronics boards provide mechanical support and electrical connectivity between a rotating electronics board and various elements of a light emission and collection engine. One or more of the optical elements of the collection optics, the illumination optics, or both, is constructed from one or more materials that absorb light outside of a predetermined wavelength range. An overmolded lens is fixedly coupled to one or more of the light detecting elements to collect incoming light over a larger range of angles. A lens element is disposed in the light path between a light emitting element and the illumination optics to flatten the intensity distribution of light emitted from the light emitting element to reduce peak intensity.

A rectenna is a combination of an antenna and a rectifier (diode). Because of limitations in nanotechnology fabrication, it has not been possible to develop rectennas that can operate in the visible frequency range. Current work has gone to producing rectennas that operate in the far infrared (thermal emission) frequency range. To harvest solar energy with rectennas to produce electric power and since rectennas cannot operate at such high frequencies, the present invention provides rectenna configurations to overcome this problem.

A method of taking an aerial survey maps boundaries of a first image and a second image from a first plane to a second plane to determine boundaries of an output image in the second plane. For a plurality of pixels in the output image, the method determines a corresponding pixel of either the first image or second image in the first plane.

A two-axis solar tracker apparatus is disclosed having multiple dish-shaped monolithic reflectors for concentrating sunlight. The dish-shaped monolithic reflectors are co-axially aligned in an array supported by a moveable frame. The moveable frame forms the elevation structure of a two-axis tracker that has control means for following the movement of the sun across the sky. Each dish-shaped monolithic reflector produces a region of concentrated sunlight suitable for generation of solar energy. A generator is positioned at the focus of each reflector. A preferred generator uses photovoltaic cells to generate electricity at a high output power due to the high solar power input that is directed to the generator by the dish-shaped monolithic reflector.
