Method to extend millimeter wave satellite communication (75-98 GHz) and 3-10 micron laser links to wide areas in the temperate zone

Pub Date: 2005-04-28

Pub Number: US20050090198

The inventor shows new, lower atmospheric attenuation in the 75-98 GHz satellite band. This lower attenuation occurs at 90% link availability. This opens up the 75-98 GHz satellite band immediately for users who can accept 90% link availability. The inventor then uses cloud autocorrelation functions to show compact switched arrays of ground sites to support availability requirements greater than 97%. This method applies to the new 75-98 GHz satellite band and the 3 micron-10 micron laser bands. These compact arrays would allow conventional availability to be attained in these previously unreliable and unattainable bands, at important temperate zone sites as New York City and Rome. The inventor shows compact square arrays with length of a side as typically less than 20 km, and discusses equilateral triangular arrays with similar lengths. Dual sites are shown to usually require larger separation distances.

Battery saver

Pub Date: 2005-04-28

Pub Number: US20050088149

The present invention is directed to a circuit that is housed within a battery that preserves the chemical energy within a battery when an external load is accidentally left on. The circuit comprises of a momentary switch, a relay, a timer and a terminal, wherein the circuit is connected to the positive and negative electrodes of a battery. The circuit is described in the circuit diagram and functions in the following manner: (1) the momentary switch detects any movement outside of the battery and sends a pulse to the relay, wherein the pulse causes the relay to close, thereby allowing electricity to flow through the circuit to the load outside of the battery, simultaneously, the momentary switch will also trigger the timer to supply power to the circuit during a timing cycle, (2) when then timer's cycle is complete, the timer's output will go low and thereby cause the relay to open and halt the flow of electricity. The terminal would be connected to the positive electrode of the battery and would have a means for connecting to the external load.

Adjustable-length compression spring and seat provided therewith

Pub Date: 2005-04-28

Pub Number: US20050088021

A compression spring comprises a casing in which a piston is arranged for displacement, the piston being mounted on a piston rod. In the casing provision is made for two sectional casing chambers which are filled with pressure fluid, at least one of which being defined by the piston. A first operating valve, in an open position, connects the sectional casing chambers to each other and, in a shut-off position, blocks the compression spring. An additional throttle element ensures that an actuation and over-flow assembly between the sectional casing chambers is completely open only when the throttle element, with the valve pin tripped, is simultaneously moved by corresponding actuation into a position of release. Without any such actuation of the throttle element, there will be only throttled flow between the sectional casing chambers. Any inadvertent extension of the piston rod is thus precluded. This is an especially convenient and intuitive way of backrest adjustment in a seat.
