Title: System and method for dynamic time division access
Inventor: BENZIMRA ALBERT
IPC: H04L12/56
Filed: 1997-05-07
Granted: 2000-12-26
Abstract: The present invention is a system and method for providing wireless packet data transmission without dependence on a fixed time slot access method or central timing mechanism. An available radio frequency (RF) channel in a communications network is divided into time frames which are further divided into time slots, wherein corresponding single time slots in each frame define a logical channel for carrying user packet data. The network includes a plurality of nodesdivided into at least two time domain groups, wherein the time domain groups aredivided into segments. Each of the time domain groups includes an independent timing source for synchronizing the time slots of logical channels within a timedomain, wherein communication between nodes is accomplished through a data messaging scheme, such as a token passing scheme. Buffer segments interface between the time domain groups. The buffer segments maintain logical synchronization for communication between interconnected time domains by dynamically reassigning the token from the logical channel of a first time domain to an unused time slot of another logical channel in response to a given offset condition. The logical channel for dynamic reassignment is chosen such that the time slot of a first time domain does not overlap the logical channel used by a second time domain.

Abstract: An implement lift system including a plurality of individual electrohydraulically controlled cylinders spaced on a tool frame and connected to lift wheel. An implement control unit (ICU) in the towing vehicle cab is connected to feedback potentiometers or similar transducers which provide signals corresponding to cylinder stroke length or suspension position. The feedback signals are compared at the ICU to a control signal obtained by rotation of a lever or knob on an operator control unit in the cab. Depending on the cylinder position relative to the operator selected position, the ICU provides an output signal to the electrohydraulic valve to achieve a proportional amount of flow for the desired cylinder position. The ICU also compares feedback signals from the transducers and adjusts the output voltage to each of the valves so that the frame can be raised and lowered evenly. In conditions where independent adjustment of different frame portions is desired, the operator control unit can be adjusted to provide the necessary offset signal for each section. The lift system provides uniform depth control and level lift for different frame configurations including frames with wings. Systems with dissimilar cylinders having different capacities or stroke lengths are easily accommodated.
