Did You Know...
...that two musicians were responsible for the invention of color print film? Fascinated by photography, Leopold Godowsky and Leopold Mannes worked together to produce an easy-to-use, practical color film. They worked full time as music teachers and gave concerts while experimenting during their off hours in Mannes' kitchen. Their success earned them full-time, well-paying jobs at Kodak and their efforts resulted in Kodachrome film, which was introduced in 1935.

| 5907403 | Optical dual Fabry-Perot interferometric strain/temperature sensor, and system for separate reading thereof A strain sensor has a first optical fiber (212) including first (212e1) and second (212e2) ends and also includes lead-in (12) and lead-out (16) optical fibers. One (12) of the lead-in and the lead-out fiber has a first end (12e) aff... | 05/25/1999 |
| 5884143 | Spacecraft with paralleled amplifiers and redundancy A spacecraft includes a plurality of paralleled RF amplifiers. Each paralleled power amplifier (206) includes a signal splitter (222) which produces two nominally equal-amplitude signals, and a signal combiner (242) which combines appropriately phased sig... | 03/16/1999 |
| 5878051 | Assembly-level bist using field-programmable gate array An assembly of logic devices intercommunicates, at least in part, by way of a data and address bus, which may not be accessible from outside the assembly. Consequently, the various logic devices, such as memories and other logic functions, cannot be direc... | 03/02/1999 |
| 5875182 | Enhanced access burst for random access channels in TDMA mobile satellite system A spacecraft (12) cellular TDMA communications system (10) includes many user terminals (16), some of which may be movable. The spacecraft repeats transmissions by way of spot beams (20). A user initiates communication by synchronizing to the TDMA slots (... | 02/23/1999 |
| 5862276 | Planar microphotonic circuits A microphotonic circuit includes one or more light control elements such as modulators or switches coupled in polymer waveguides, and controlled by electrical bias fields produced by voltage or light sources. Each modulator or switch includes at least one... | 01/19/1999 |
| 5860865 | Pneumatically driven auto-balance rotor hub A pneumatically operated autobalance arrangement includes a hub which connects a shaft with a driven rotational element. The hub is fitted with a plurality of circumferentially-acting bellows which move weights about the hub. The inflation state of each b... | 01/19/1999 |
| 5811755 | Weld repair method for aluminum lithium seam Aluminum-lithium plates are butt-welded by juxtaposing the plates and making a preliminary weld from the rear or root side of the seam. An initial weld is then made from the face side of the seam, which may cause a defect in the root portion. A full-size ... | 09/22/1998 |
| 5765361 | Hybrid-LO2-LH2 low cost launch vehicle A low-cost rocket or thruster has a low-cost propellant injector, in which fluid fuel and oxidizer are injected into a combustion chamber. The walls of the combustion chamber are protected from the high temperatures of the combustion by a grain of solid p... | 06/16/1998 |
| 5396231 | Modular communications interconnection A communications system (FIG. 7) couples together a number of entities or communications devices 710 by means of alternating stages (722, 726) of crossbar switches (712, 716) and stages (724, 728) of stride extender coupler circuits, which are preferably ... | 03/07/1995 |
| 5243690 | Robot targeting using transit time control A robot is controlled to move from a predetermined rest point to contact a moving target. The control parameters of the robot are not known. Control is effectuated by predetermining the time required for the robot to move from a rest position to each of a... | 09/07/1993 |
