  • Patent number: 9169926
    Abstract: A system and method involves a machine that powertrain including a continuously variable transmission (CVT) and a machine speed sensor to determine a measured machine speed. The machine also includes a controller in communication with the CVT and the speed sensor. The controller may include a table relating the measured machine speed to a plurality of virtual gear ratios associated with the CVT. The controller is configured to determine a calculated virtual gear ratio using the table and, if desired, may display the calculated virtual gear ratio on a visual display.

  • Publication number: 20150271130
    Abstract: Systems and methods of the present disclosure facilitate provisioning an out-of-band system. In some embodiments, the system includes a server of a first domain, which includes a management engine. The management engine can establish a network tunnel with a device on a second domain, and modify the domain on a DHCP server on the second domain to be the first domain. The device can use a fixed subdomain of the first domain to transmit a provisioning request for an OOB management system to a provisioning engine in the first domain, which can transmit a certificate including the first domain to the device. The device can validate the certificate by comparing the domain in the certificate to the domain from the DHCP server and verify that they match. The management engine can modify the DHCP server to have the original second domain.

  • Patent number: 9126578
    Abstract: A machine includes an engine and an engine cooling system, which is associated with and configured to remove heat from the engine. A transmission is connected to the engine and configured to transmit engine power from the engine to a driven load. The transmission controls an amount of engine power transmitted to the driven load in response to a transmission command signal. A controller associated with the engine and the transmission provides the transmission control signal. The controller is disposed to determine an engine operating condition, determine a transmission operating condition, and adjust the transmission command signal to reduce the amount of engine power transmitted to the driven load when the engine operating condition indicates that the engine cooling system removes insufficient heat from the engine.

  • Publication number: 20150147183
    Abstract: A propeller blade assembly including a propeller blade having a leading edge, and a trailing edge extending between a tip and a hub, and an electrically conductive band extending longitudinally on either or both of the leading edge and trailing edge. The electrically conductive band secured to the leading edge of the propeller serves as an entry point on the aircraft and conductive channel into the airframe thereby avoiding the potentially damaging effect of the lightening on the carbon fiber composite propeller.

  • Patent number: 9002595
    Abstract: A method regulates the torque output and/or speed output of a continuously variable transmission (CVT) in a manner that may simulate a clutch. The CVT may be incorporated in a machine and maybe operatively coupled to a power source and to a propulsion device. The method utilizes an unaltered torque-to-speed curve that relates the torque output to the speed output of the CVT. The method may receive an operator input signal indicating a desire to change operation of the machine. The torque-to-speed curve may be shifted in response to the operator input signal to limit the torque output available. In an aspect, an under-run curve may be applied to the torque-to-speed curve, the under-run curve corresponding to a target speed. The operator input signal may also shift the under-run curve to reduce the target speed.

  • Patent number: 8874332
    Abstract: A system and method involves a machine having a power train including a continuously variable transmission (CVT) associated with a plurality of virtual gear ratios. To shift between the plurality of virtual gear ratios, the machine may include an operator input device that may be movable between a plurality of distinct positions. A first position may be associated with a neutral position in which no shifting of virtual gear ratios occurs. A second position of the operator input device may be associated with a first incremental rate for shifting between the virtual gear ratios. A third position may be associated with a second incremental rate for shifting between the virtual gear ratios which is different than the first incremental rate.

  • Patent number: 8849527
    Abstract: A machine may include a continuously variable transmission (CVT) operatively coupled to a power source. A virtual gear ratio may be selected from a plurality of virtual gear ratios associated with the CVT. A power source speed may be locked between a minimum power source limit and a maximum power source limit that are associated with the selected virtual gear ratio. If the virtual gear ratio is changed, a controller including one or more control maps may compare the power source speed as locked to the minimum power source limit and the maximum power source limit as they relate to the newly selected virtual gear ratio. If power source speed is outside the minimum or maximum power source limits, the method may limit the power source speed. In some embodiments, the minimum and/or maximum power source limits may vary with respect to the plurality of virtual gear ratios.

  • Patent number: 8795133
    Abstract: A method controls the power-transmission in a machine having a continuously variable transmission (CVT) and a power source operatively coupled together in a powertrain. The method regulates operation of the CVT with a retarding power limit in order to limit the amount of retarding power transferable from the powertrain to the power source. The retarding power may be utilized to decelerate or decrease the speed of the machine. The method may register an operator input signal indicative of a deceleration event from a plurality of possible deceleration events. The deceleration event is compared to a lookup table to determine if the retarding power limit should be adjusted. The method may adjust the retarding power limit in accordance with the comparison.

  • Publication number: 20140075549
    Abstract: A mechanism for allowing a user to prove their identity on touch-based devices employing the use of a touch surface in firmware-controlled environments is discussed. The user may prove his or her identity by entering a series of strokes on the touch-based device to form a word or image. Characteristics of the entered strokes such as stroke order and stroke direction are compared to stored stroke characteristics that were gathered from a drawing of the same word or image during a user enrollment process. If the stroke characteristics comparison is acceptable, the user identity is verified.

  • Patent number: 8585543
    Abstract: A system and method of controlling the speed of a machine having a continuously variable transmission (CVT) operatively coupled to a power source. A plurality of selectable virtual gear ratios can be associated with the CVT. The machine may include an operator input device that may generate a operator input signal indicative of a desired adjustment in the ground speed. The operator input signal may be converted to a CVT speed command and to a power source speed command that are communicated to the CVT and the power source, respectively. The CVT adjusts the machine speed in accordance with the CVT speed command, while the power source adjusts its speed in accordance with the power source speed command, so that operation of the power source is substantially independent of operator of the CVT.
