摘要： Equipment and methods for aligning the antennas of two transceivers of a point-to-point wireless millimeter wave communications link and keeping them aligned. Each of two communicating antennas is equipped with a telescopic camera connected to a processor programmed to recognize landscape images. The processors are programmed to remember the pattern of the landscape as it appears when the antennas are aligned. Each of the cameras then view the landscape periodically or continuously and if the landscape in view changes by more than a predetermined amount a signal is provided to indicate a misalignment. An operator can then take corrective action or alternatively the antenna system can be configured for remote or automatic realignment based of feedback from the camera. In a preferred embodiment, the antennas are initially aligned by substituting a narrow band oscillator power source for the signal transmitting electronics associated with a first antenna and a power detector is substituted for the signal receiving electronics of associated with a second antenna.

摘要： A point-to-point, wireless, millimeter wave trunk line communications link at high data rates in excess of 1 Gbps and at ranges of several miles during normal weather conditions. This link is combined with an Ethernet network to provide high speed digital data communication among a large number of users. In a preferred embodiment a trunk line communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. A first transceiver transmits at a first bandwidth and receives at a second bandwidth both within the above spectral range. A second transceiver transmits at the second bandwidth and receives at the first bandwidth. The transceivers are equipped with antennas providing beam divergence small enough to ensure efficient spatial and directional partitioning of the data channels so that an almost unlimited number of transceivers will be able to simultaneously use the same spectrum. Antennas and rigid support towers are described to maintain beam directional stability to less than one-half the half-power beam width. In a preferred embodiment the first and second spectral ranges are 92.3-93.2 GHz and 94.1-95.0 GHz and the half power beam width is about 0.36 degrees or less. In this preferred embodiment the Ethernet network is a Gigabit Ethernet providing data communication among switch banks at 1 gigabits per second and communication among a large number of users at 100 Mbps.

摘要： A wireless cellular communication system in which groups of cellular base stations communicate with a central office via a narrow-band millimeter wave trunk line. The transceivers are equipped with antennas providing beam divergence small enough to ensure efficient spatial and directional partitioning of the data channels so that an almost unlimited number of transceivers will be able to simultaneously use the same millimeter wave spectrum. In a preferred embodiment the trunk line communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. A large number of base stations are each allocated a few MHz portion of a 900 MHz bandwidth of the millimeter wave trunk line. A first transceiver transmits at a first bandwidth and receives at a second bandwidth both within the above spectral range. A second transceiver transmits at the second bandwidth and receives at the first bandwidth. Antennas are described to maintain beam directional stability to less than one-half the half-power beam width. In a preferred embodiment the first and second spectral ranges are 92.3-93.2 GHz and 94.1-95.0 GHz and the half power beam width is about 0.36 degrees or less. Thus, in this system the low frequency band width is efficiently utilized over and over again by dividing a territory into small cells and using low power antenna. And a higher frequency bandwidth is efficiently utilized over and over again by using transmitting antennae that are designed to produce very narrow beams directed at receiving antennae. In a preferred embodiment cellular base stations are prepackaged for easy quick installation at convenient locations such as the tops of commercial buildings.

摘要： A point-to-point, wireless, millimeter wave communications link providing data transmission rates of over 1 billion bits per second (more than 1 Gbps) at ranges of several miles during normal weather conditions. In a preferred embodiment a communication link operates within the 92 to 95 GHz portion of the millimeter spectrum. A first transceiver transmits at a first bandwidth and receives at a second bandwidth both within the above spectral range. A second transceiver transmits at the second bandwidth and receives at the first bandwidth. The transceivers are equipped with antennas providing divergence of less than 10−4 steradians so that an almost unlimited number of transceivers can use the same spectrum. In a preferred embodiment the first and second spectral ranges are 92.3-93.2 GHz and 94.1-95.0 GHz. During very bad weather conditions this data link will not provide a 10−10 bit-error rate and 99.999% availability. Therefore, a second transceiver pair operating in the 3 to 30 GHz microwave range acts as a backup to achieve the above bit-error rate and availability requirements, but at a temporarily lower data rate.

摘要： A microwave incinerator is configured to incinerate waste material. The waste material is installed within a microwave absorbing shroud located in a microwave chamber. The combination of low microwave heat input and a vacuum drawn on the chamber vaporizes the water in the garbage. During this first phase there is no combustion because of the relatively low temperature and the lack of oxygen. Once the material is dry, intense microwave energy is applied to the chamber heating the silicon carbide shroud to an elevated temperature in the range of about 500 to 1000 degrees C. Concurrent with the rapid rise in temperature, air containing oxygen is pumped into the chamber. The hot shroud ignites the material, after which heat is provided is a combination of combustion heat and microwave energy. The temperature is monitored and the microwave energy input is controlled to assure a controlled burn of the waste material.

摘要： A thin diamond electron beam amplifier. The illumination side of a thin diamond is illuminated by a seed electron beam creating electron-hole pairs in the diamond. A voltage potential provides an electric field between the illumination side of the diamond and an acceleration grid opposite the emission side of the diamond. Electrons released in the diamond are accelerated through the emission side of the diamond toward the acceleration grid creating an amplified electron beam.

摘要： A process for the removal of superficial epidermal skin cells in the human skin. A contaminant having a high absorption at at least one wavelength of light is topically applied to the surface of the skin. Some of the contaminant is forced to infiltrate into spaces between the superficial epidermal cells. The skin section is illuminated with short laser pulses at the above wavelength, with at least one of the pulses having sufficient energy to cause some of the particles to explode tearing off the superficial epidermal skin cells. In a preferred embodiment, the contaminant includes 1 micron graphite particles and the laser used is a Nd:YAG laser.
