1. This is claimed to be a piece of tubing or bar with a cleat attached that mounts to an existing trailer hitch for the purpose of tying rope easily and disengaging the rope quickly and with little effort:
This hitch cleat can be developed to fit a class 1, class 2, and class 3 or class 4 trailer hitches.
The hitch cleat can be made of aluminum, steel, stainless steel, titanium, magnesium, brass, bronze, reinforced plastic, or any material of suitable strength.
The hitch cleat could contain one through hole.
The hitch cleat could be bolted instead of welded, or forged or cast as a single piece.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A communication system comprising:
a transmitter and receiver in communication for transmitting signals through one or more communications channels;
wherein at least one of the transmitter and the receiver comprise a quality measure, which contributes to an overall quality measure for the system;
wherein each communications channel comprises a plurality of sub-bands between at least two nodes, wherein the plurality of sub-bands each has a specific maximum power spectral densities (PSDs);
wherein one or more sub-bands between the transmitter and the receiver are identified as having a higher maximum PSD than other sub-bands; and
wherein the PSD of the one or more identified sub-bands is reduced in a predetermined manner to thereby increase the overall quality measure for the system.
2. A communication system as claimed in claim 1, wherein the quality measure is transmitted to the transmitter to indicate that the PSD can be reduced for the one or more identified sub-bands.
3. A communication system as claimed in claim 1, wherein a substantial improvement of the quality measure of the other signals in at least some of the remaining sub-bands is iteratively analyzed to determine the change of the quality measure and to adjust a bit loading of the signals in substantially all of the sub-bands, based on the quality measure of the received signals until an overall quality measure of the signals in substantially all of the sub-bands, is optimized to thereby increase an available throughput.
4. A communication system as claimed in claim 1, wherein after reducing the PSD, the quality measure of the one or more identified sub-bands is analyzed to determine any change in the quality measure of the one or more identified sub-bands.
5. A communication system as claimed in claim 1, wherein after reducing the PSD, the quality measure of other sub-bands is analyzed to determine any change in the quality measure of the other sub-bands.
6. A communication system as claimed in claim 1, wherein the level of the PSD into the one or more identified signals is determined by considering predetermined criteria of the signals, the channel and the sub-bands.
7. A communication system as claimed in claim 1, wherein a predetermined PSD profile for the one or more sub-bands is requested.
8. A communication system as claimed in claim 1, wherein a channel and a PSD are allocated for each node.
9. A transmitter for communicating with a receiver over a communication system as claimed in claim 1.
10. A receiver for communicating with a transmitter over a communication system as claimed in claim 1.
11. A method for a communication system comprising:
a transmitter and receiver in communication for transmitting signals through one or more communications channel;
wherein at least one of the transmitter and the receiver comprise a quality measure, which contributes to an overall quality measure for the system; and
wherein each communications channel comprises a plurality of sub-bands between at least two nodes;
wherein the plurality of sub-bands each has a specific maximum power spectral densities (PSDs), the method comprises the steps of:
identifying one or more sub-bands having a higher PSD than other sub-bands between the transmitter and the receiver; and
reducing the PSD of the one or more identified sub-bands in a predetermined manner to thereby increase the overall quality measure for the system.
12. A computer program comprising instructions for carrying out the method of claim 11 when said computer program is executed on a programmable apparatus.
