An Agile-Beam Laser Array Transmitter (ABLAT) uses an array of emitters and an array of lenses to project electromagnetic beams over a wide angular coverage area in the far field. Differences in the separation pitches of the two arrays allows the ABLAT to project beams to contiguous and/or overlapping positions, depending on the ratio of the separation pitches and the lens focal length. Compared to other beam steering technology, the ABLAT is a smaller, lighter, and more efficient means of projecting beams over wider angular coverage areas. Various embodiments can be used in any beam steering application, including, but not limited to: free-space optical communications; light detection and ranging (lidar); optical scanning (e.g., retinal or bar-code scanning); display projection; image capture; optical character recognition; scanning laser microscopy; non-destructive testing; printing; facsimiles; map making; web inspection; color print processing; phototypesetting and platemaking; laser marking; material processing; DNA analysis; and drug discovery.

Each service providing device has a proxy process step of specifying a specific communications capability in response to a communications capability request from any client device when a predetermined service providing process is not performed in a predetermined period, allowing any service providing device in a network to perform as a proxy a communications process based on the specified specific communications capabilities, and making a transition to a network sleep status not recognized by a client device in the network.

Thermally adjustable surgical tools include a conductor and a ferromagnetic material. The ferromagnetic material may be quickly heated when subjected to high frequency alternating current through the conductor. The ferromagnetic material may also cool rapidly because of its relatively low mass and the small thermal mass of the conductor. The thermally adjustable surgical tools may be used to sculpt, melt, break and/or remove biological material. The thermally adjustable surgical tools may also include balloon catheters which can heat fluid to thereby treat biological material.

A system for providing mechanical stabilization with automated corrections for stationary or mobile surveillance platforms comprises: a telescoping mast that supports a sensor package containing a camera, surveillance radar, a pan tilt unit, and a tilt sensor with a precision compass. Stabilization involves hardware and software enhancements to conventional surveillance systems. Mast stabilization is achieved by a mechanical guy-wire arrangement which provides for both anti-twist and anti-sway support of the mast upper end through a crisscrossed guy wire arrangement.
