Title: Hog pen flooring
Inventor: YOUNG STUART DOUGLAS
IPC: A01K1/015
Filed: 1992-04-03
Granted: 1996-09-17
Abstract: A plurality of rectangular, hexagonal concrete slabs are employed and adjacentlydisposed to form a flooring for a hog pen having elevated sides or margins. Each slat has a plurality of apertures so that the porosity of the slat, in closer proximity to the walls of the pen, is greater than through the central region of the pen. This provides, because of the observed behavior of the hog, a greater porous region adjacent the walls of the pen where the animal tends to defecate, the defecation running through the slots into a collection region below the elevation of the slats. The central region which has a less porosity, is more suitable for the animal to walk or lay upon. When the animal walks near the sides of the pen, the hoof action of the hog on the slat tends to push any feces collected on the top of the slat through the apertures into a collection region below the elevation of the slats and hence, the pen is maintained clear of defecation by the actual movement of the hogs. Pen cleaning by the farmer is reduced or avoided.

Title: Variable rate communication method and a variable rate communication system
Inventor: ASANO NOBUO
IPC: H03M13/41
Filed: 1994-07-07
Granted: 1999-02-23
Abstract: In variable rate communications in which a bit rate changes at B/2n (where n is 0 or a positive integer) in each frame when a maximum information rate is B, at a transmitter side information data is convolution coded in order to carry out an error correction of the information data.  When n~1, coded data is repeatedly transmitted by (2n - 1) times so that the information rate B is set to be equal to a data rate when the information rate B has been convolution coded.  At a receiver side, an information rate is detected from the transmission data that has been received, and when carrying out a Viterbi decoding, a rate is estimated by utilizing the characteristics that data are repeated, so that the coded data is Viterbi decoded for only the estimated rate.  This restricts an increase in the power consumption of the mobile terminal units that are driven by batteries.

Title: Highly dynamic destination-sequenced destination vector routing for mobile computers
Inventor: PERKINS CHARLES E
IPC: H04L12/56
Filed: 1994-10-21
Granted: 1999-08-24
Abstract: Packets are transmitted between stations of an ad-hoc network of mobile stations by using routing tables which are stored at each station of the network. Routing information is broadcast or multicast according to three schedules;  upon demand to show new routes, periodically to show recently changed routes, and less often to provide a complete dump of all known routes. A new route will trigger immediate re-broadcast so that this information is quickly disseminated. A new route is defined to be one with a better metric or a metric of infinity. A metric of infinity indicates a broken link; i.e., a particular destination is no longer reachable and thus all other destinations depending upon the newly unreachable destination are themselves unreachable. Periodically, routes are advertised.  This advertisement serves primarily in most cases to notify all neighbors that everything they have stored is still correct regarding the broadcasting Mobile Host. On rarer occasions when the routing topology changes, the demand nature of the incremental update displaces the periodic transmission until an update interval transpires. In order to damp out oscillations, data is kept about how often the routes change. Based on this data, a decision may be made to delay advertising routes which are about to change soon, thus damping oscillations of the route tables.
