Methods and systems for forward-looking tone allocation are provided. In one embodiment, a method for an orthogonal frequency division multiplexing (OFDM) multipoint-to-point communications system comprises: establishing communication between a plurality of remote units and a host unit, the remote units communicatively coupled to the host in a multipoint-to-point configuration; transmitting a plurality of tones from the remote units, such that tones from more than one remote unit are simultaneously received at the host, the tones modulated with upstream information using OFDM; adjusting at least one characteristic of at least one tone at least one remote unit, in response to adjustment commands from the host, such that the orthogonality of the simultaneously received tones is improved as received at the host unit; and dynamically switching modulation from at least a first tone of the plurality of tones to a second tone based on an error-rate history of the second tone.

A method for an orthogonal frequency division multiplexing multipoint-to-point communications system is provided. The method includes establishing communication between a first remote unit of a plurality of remote units and a host unit, the plurality of remote units communicatively coupled to the host unit in a multipoint-to-point configuration, transmitting up to a plurality of tones from the first remote unit, the up to a plurality of tones modulated with upstream information using orthogonal frequency division multiplexing, and receiving information from the host unit to adjust transmission of the up to a plurality of tones from the first remote unit such that when any tones are transmitted from the first remote unit and at least one other remote unit of the plurality of remote units, all of the tones are substantially orthogonal when received at the host unit.
Abstract:
A bidirectional communication system is provided. In one embodiment, a system comprises a host; and a plurality of remote units, wherein a plurality of tones is shared among the plurality of remote units in order to communicate with the host using orthogonal frequency division multiplexing, wherein the plurality of tones is shared in a manner that permits at least two of the remote units to transmit to the host at any one time using the plurality of tones. The host causes at least one remote unit to adjust a timing of symbols transmitted on at least one of the plurality of orthogonal tones in order to improve an alignment of multiframes received at the host.
Abstract:

Abstract:
A vehicle steering system includes a steering input device, a front steering subsystem, a rear steering subsystem, a first force transmission route, a steering control mechanism, a second force transmission route, and a third force transmission route. The front steering subsystem is coupled to front motive members to steer the front motive members based upon movement of a front steering subsystem input shaft. The rear steering subsystem is coupled to rear motive members to steer the rear motive members based upon movement of a rear steering subsystem input shaft. The first force transmission route extends from the steering input device to the front steering subsystem input shaft, wherein force is transmitted from the input device to the front steering subsystem input shaft to steer the front motive members. The steering control mechanism has a movable input member and a movable output member. The movable input member is movable through a first distance without transmitting force to the output member and is movable through a second distance in which force is transmitted to the output member to move the output member. The second force transmission route extends from the steering input device to the input member, wherein force is transmitted from the input device to the input member to move the input member. The third force transmission route extends from the output member to the rear steering subsystem input shaft to move the rear steering subsystem input shaft and to steer the rear motive members.
Abstract:
A liquid pump for pumping groundwater samples from small diameter sub-terrain wells, comprising a tubular casing having inlet apertures, a top cap provided with a fluid communication port and a liquid outlet port, a top bladder mandrel secured to the top cap, a mandrel sealing member disposed in a lower end of the casing, a bottom bladder mandrel secured to the mandrel sealing member, and a flexible bladder extending between the top bladder mandrel and the bottom bladder mandrel and defining a liquid chamber for receiving the liquid therein and a fluid chamber for receiving a fluid under pressure therein that surrounds the liquid chamber, with the bladder disposed therebetween. The fluid chamber is in fluid communication with the fluid communication port connected to a source of the actuating gas, while the liquid chamber is in one-way fluid communication with the liquid inlet and the liquid outlet port.
Abstract:
Dyestuffs are provided which contain one or more 1,3-dicyanobenzene radicals linked to the dyestuff at the 2-, 4- or 6-position, with halogen substituents in both of the remaining two of these positions and an electron-attracting substituent in the 5-position. These dyestuffs reactively dye cellulose at low temperatures and are less prone to "acid-bleeding" than some known reactive dyes. More particularly, those dyestuffs have the formula: ##STR1## where D is a chromophoric groupn is 1 or 2, ##STR2## where R is H, C.sub.1-4 alkyl, C.sub.1-4 alkyl substituted by OH, OSO.sub.3 H, CN or SO.sub.3 H or is phenyl.Each hal independently represents a chlorine or fluorine atom occupying one of the remaining 2-, 4- and 6-positions of the benzene nucleus, and Y is H, F, Cl, CN, NO.sub.2 or SO.sub.3 H.
