Draft control method for operating an earth moving machine
The hitch on a vehicle is moved by a hydraulic actuator. A method for controlling the hydraulic actuator defines a draft force setpoint in response to separately averaging two forces acting on lateral sides of the hitch, while operating in a configuration mode. During regular operation, a draft load is calculated from sensing those two forces and deriving a draft force error from difference between the draft load and the draft force setpoint. The draft force error is used to control fluid flow to and from the hydraulic actuator. One aspect of the control method derates the draft force error as the hitch moves beyond a predefined threshold position.

Service flow with robust header compression (ROHC) in a WiMAX wireless network
A robust header compression (ROHC) controller provides for service flow processing of a ROHC channel in a WiMAX wireless communication system. The ROHC controller controls the negotiations of the MS ROHC capabilities during its registration and the negotiations of the ROHC channel parameters during ROHC enabled service flow setup; the MS ROHC capabilities including ROHC compression and decompression capabilities and ROHC channel and feedback strategies; the channel parameter negotiation covers the ROHC profile set and feedback channel information in addition to the 16e/12D standard. The ROHC controller receives a service flow request for a ROHC enabled service flow, wherein the request includes a QoS profile.
Apparatus and method for allocating radio network temporary identifier for random access in a mobile communication system
An apparatus and method for allocating Radio Network Temporary Identifiers (RNTIs) for random access in a mobile communication system are provided. An Evolved Node B (ENB) determines the number of RNTIs allocated to at least one User Equipment (UE) that transmitted a random access preamble, determines an average number of random access preambles received during a Transmission Time Interval (TTI), and sets a timer based on the number of allocated RNTIs and the average number of random access preambles. If a cell identifier corresponding to a first UE is not received from an upper layer before expiration of the timer, the ENB releases the RNTI allocated to the first UE, and allocates the released RNTI to a second UE different from the first UE.
