The engine speed may also be limited to reduce the engine speed to prevent it from exceeding the allowable PTO speed. | 09-03-2009 |
20090305845 | AUTOMATIC DISENGAGING/ENGAGING METHOD OF A CLUTCH DEPENDENT POWER TAKE-OFF - An automatic disengaging method for a master clutch dependent power take-off (PTO) arranged in a vehicle for preventing undesired movement or actions of the implements associated with the PTO and undesired wear of a clutch collar (release bearing). The PTO is driven by an engine via a master clutch between a crankshaft of the engine and an input shaft in a gearbox. The gear box further comprises an output shaft which is powered by the input shaft, optionally via an intermediate shaft. A power take-off is connected to the input shaft or, optionally, to the intermediate shaft. The system further includes a control unit connected to the master clutch and the gear box. When the control unit registers that the master clutch is disengaged, a gear is engaged in the gearbox and certain conditions are fulfilled (e.g. a parking brake has been actuated for a certain time), the control unit performs the operations of putting the gearbox in a neutral position, disable the power take-off, if the power take-off is enabled, and engage the master clutch. | 12-10-2009 |
20100075804 | METHOD FOR CLUTCH PROTECTION - Method for protecting a clutch of a vehicle, said vehicle being provided with an engine, drive wheels and an automated manual transmission for transmitting drive power from said engine to said drive wheels. A controller can execute the steps of: sensing a power demand from the driver which results in a clutch control where the clutch is partly engaged and clutch slip occurs, measuring travelling distance(s) of the vehicle during a predetermined first time interval, initiating a first warning measure, in order to alert the driver of excessive clutch slip, if the vehicle has traveled less than a predetermined distance during said predetermined first time interval. | 03-25-2010 |
20110010060 | METHOD AND DEVICE FOR AUTOMATIC OR SEMIAUTOMATIC SELECTION OF A BETTER STARTING GEAR IN A VEHICLE - Method and a device for automatic selection of a better starting gear in a vehicle, including the steps of engaging a first starting gear, on driver demand controlling propulsion torque as to attempt to achieve a first take off, if the first starting gear is too high interrupting the first take off and automatically braking the vehicle, engaging a second adapted starting gear which is a lower gear compared to the first starting gear, controlling propulsion torque as to attempt to achieve a second vehicle take off, and if the second vehicle take off attempt results in a transmitting of torque to driven wheels of the vehicle being enough as to perform a take off then stop braking the vehicle. An incorrectly selected starting gear can thus be automatically changed. The starting gear change can be performed in an uphill situation. | 01-13-2011 |

20090243818 | Method and apparatus for detecting the presence and locations of radio controlled improvised explosive devices in real time - A Method and Apparatus for Detecting the Presence and Locations of Radio Controlled Improvised Explosive Devices in Real Time. The system will clandestinely detect the presence and location of RCIED's along roadways in real time. This “RCIED Street Sweeper” system consequently allows its users to remove the explosive devices, pre-detonate them, or simply avoid the location so that the weapons cannot be used against a convoy or other important target. The system has the abilities (disclosed in U.S. patent application Ser. No. 10/829,858) to conduct fast wideband scanning of the RF spectrum looking for ambient RF signals as well as RCIED leakage signals. Furthermore the system has the ability to correlate the received leakage signals with the ambient RF signal environment, in order to verify authenticity. Still further, the system has the ability to continually mark and record the precise map location where each of those RF spectrum measurements emanated, including the relative distances between them. Still further, the preferred system will calculate adjusted curve profiles given the real time distance data. Fifth, the preferred system needs to have the ability to correlate sets of trend data with the adjusted curve profiles to determine matches. Further yet, the system alerts the vehicle driver to the presence and location of any RCIED that is detected by the system. Finally, the system is capable of being installed in a low profile, clandestine manner on a mobile platform such as a car or truck, so as not to alert insurgents of its existence. | 10-01-2009 |
20140104110 | Method for Real-time, Automatic, Wideband, High Accuracy RF Direction Finding - This system and method provides a direction finding system that enables modern RF DF systems to analyze short duration signals in the entire instantaneous bandwidth. By providing a method to process wideband data, the invention drastically improves throughput and probability of intercept (POI). The invention is unique in that it does not require separate narrowband channels for analysis, and can simultaneously calculate azimuth and elevation estimates for every frequency in the bandwidth of an incident signal. It is also well-suited for fixed point, FPGA implementations making it a perfect match for modern state-of-the-art processing systems. The system and method capitalizes on the ability of Fourier Frequency Transform operations to accurately resolve incident wave phase at discrete frequencies. The system then uses the phase information from the individual elements in the array to arrive at an emitter azimuth angle. The azimuth angle is nearly simultaneously used in concert with lookup tables of all possible elevation angles to compare the arrival time delay between the array elements to determine emitter elevation angle. | 04-17-2014 |
20140108595 | Technique for Efficient Message Delivery in Ad Hoc, Mesh, Wireless Computer Networks - A Technique for Efficient Message Delivery in Ad Hoc, Mesh, Wireless Computer Networks. The method and system of the present invention permits reliable wireless messaging between nodes on an ad hoc basis. The method is executed at each node in an iterative fashion, If a node is not the destination node for a particular message, that node will retransmit a received message. As the message is received and retransmitted from node to node, the message will propagate through the networked nodes until it reaches its destination node. In order to prevent the retransmission of messages into perpetuity, the method will limit the number of times that a particular node can retransmit a particular message. Once that retransmission limit is reached by a particular node for a particular message, the message retransmission will cease at that node, and the message will expire. The message will also expire after a pre-set time to live parameter has elapsed. | 04-17-2014 |
