20140303814 | Aerial farm robot system for crop dusting, planting, fertilizing and other field jobs - Modern farming is currently being done by powerful ground equipment or aircraft that weigh several tons and treat uniformly tens of hectares per hour. Automated farming can use small, agile, lightweight, energy-efficient automated robotic equipment that flies to do the same job, even able to farm on a plant-by-plant basis, allowing for new ways of farming. Automated farming uses unmanned aerial vehicles (UAVs) that are equipped with detachable implements and reservoirs and that we call “aerial farm robots.” Automated farming uses high-precision GPS and other precision positioning and vision technology to autonomously and precisely perform crop dusting, planting, fertilizing and other field related farming or husbandry tasks. The subsystems for the control, refill, recharge and communication subsystems of the aerial farm robots are part of the overall automated farming system, and can autonomously handle most of the husbandry tasks on a farm. | 10-09-2014 |

20080218921 | Control Circuit with Reduced Load for a Bypass Switch - The invention relates to a control circuit for controlling the power supplied from a power source to an electromotor, whereby the control circuit comprises a semiconductor switching element connected in series to the electromotor and the power source for controlling the power supplied to the electromotor and operating means connected to the semiconductor switching element for controlling the semiconductor switching element, whereby the operating means are arranged for controlling the semiconductor switching element when the control range of the semiconductor switching element is exceeded for at least a moment in a fully conducting state. Because the current reaches this value for at least a moment, the switch no longer has to interrupt a relatively large current. | 09-11-2008 |
20090102404 | Control Circuit For An Electromotor With Electronic Brake Switch - The invention relates to a control circuit for controlling a DC voltage power supply, whereby the control circuit comprises a switching element connected in series to the motor and a bypass switch connected in parallel to the electromotor for braking the electromotor by means of bypassing, with the bypass switch being formed by a semiconductor and the control circuit comprising a control circuit for controlling the bypass switch and a detector connected to the control circuit for detecting the status of the switching element. Semiconductors are less sensitive to vibrations and dirt. They are furthermore so small that they can easily be mounted on the same carrier as the other components of the control circuit. The control circuit is preferably arranged for gradually increasing the conductivity of the bypass switch once the switching element is open. Mechanical shocks when the tool is switched off are prevented by means of the partial conductivity of the semiconductor switch. | 04-23-2009 |
20090190905 | Regulator Circuit for an Electric Motor, Provided with a Microprocessor - The invention relates to a regulator circuit for controlling the power fed to an electric motor from a voltage source, wherein the regulator circuit comprises a semiconductor switching element connected in series to the electric motor and the voltage source for the purpose of controlling the power fed to the electric motor, a control circuit for controlling the semiconductor switching element, and a first operating element for operating the control circuit by means of an operating signal generated by the operating element and fed to the control circuit, wherein a microprocessor is incorporated in the control circuit. The microprocessor can be adapted to control numerous functions within the regulator circuit, in particular monitoring and safety functions. It is however also possible for the microprocessor to be adapted to control the power fed to the electric motor subject to the operating signal. This can relate to performing of this single function as well as to performing this function in combination with safety functions. | 07-30-2009 |

20080266805 | Carrier For Electrical Components With Soldered-On Cooling Body - The invention relates to an assembly of a carrier for electrical components that are arranged for producing more heat than can be dissipated via natural cooling at least under certain operating conditions and a cooling body mechanically and thermally connected thereto, whereby the carrier is provided with a metal part that is connected to the cooling body by means of a metallic connection. Mounting a metal part on the carrier makes it possible to form a metallic connection between the metal part and the metal cooling body. The invention also relates to a method for assembling an assembly of a carrier for heat-producing electrical components and a cooling body mechanically and thermally connected thereto, whereby the components are initially mounted on the carrier and a metal part of the carrier is then connected to the cooling body by means of a metallic connection. | 10-30-2008 |
