摘要:
An intercom system is provided having a plurality of intercom stations coupled to a digital network, each station transmitting intercom data onto a channel of the network. Each station receives intercom data from each other station and selects channels to be amplified and output to a speaker. Each station may listen to and talk to any other station or any selected group of stations. Processing of signals from the network is performed in each station, thereby eliminating the need for a centralized mixing and switching device. Stations may be added merely by connecting them to the network. The intercom system may be configured in a non-blocking mode or in a blocking mode.

Water-dispersible particles are provided that disperse into more than 100 pieces upon contact with water. Particles include from 5% to 99.9% of a nitrogen-containing ingredient bioavailable to a targeted desirable organism and 1% to 95% of a bentonite binder component. Additionally provided is a process for making a water-dispersible particle, the process including the steps of mechanically aggregating particle components into a pellet. Particle components include a bioavailable nitrogen-containing ingredient and a binder, the components being such that a product particle is dispersed into more than 100 pieces upon contact with water. In a further step of a process for making a water-dispersible particle, the pellet is dried to form a particle. Following administration of a described particle, water is allowed to contact the particle, dispersing it into pieces and thereby delivering a nutrient.

An organic carrier member for mounting a semiconductor device is provided that has a plurality of solder pads containing low amounts of tin and bismuth. Embodiments include a bismaleimide-triazine epoxy laminate having a plurality of solder pads on the surface thereof where the solder pads contain no more than about 20 weight percent tin and has a reflow temperature of no greater than about 270° C.

An integrated circuit package includes at least one one-time programmable element, such as a fuse, having a first end and a second end separated by a programmable link. The programmable element is positioned on a surface other than the top surface, e.g., a side surface or the bottom surface of the package substrate to render them less conspicuous to unscrupulous suppliers intent on tampering with the package. The information programmed by the fuses may relate to speed or voltage ratings for a microprocessor.

A watercraft docking system for receiving watercraft along side of a dock. The watercraft docking system having a first and a second support member which are coupled to an elongated roller to allow the elongated roller to rotate on the longitudinal axis. The watercraft docking system is mounted on a dock, where the dock has a support structure and a dock platform having a walking surface. The first and second support members are secured to the support structure to hold the elongated roller at a predetermined distance from the dock.
摘要:
A color wheel comprised of two or more interference filters deposited on or bonded to a substrate 30 without the use of a frame or spokes. Filters 32, 34, and 36 preferably abut and are typically made from multiple layers of materials having different indices of refraction. The color wheel does not require extensive machining or balancing, and is very optically efficient because the duration of single color light periods is maximized. The color wheel does not have a frame or spokes and is therefore more aerodynamically efficient resulting in less work required to spin it and less wind noise.
