  • Publication number: 20210291010
    Abstract: An exercise apparatus includes a linear arm portion having an elongate arm member with proximal and distal ends and an elongate support member having proximal and distal ends. The arm member can be slidably mounted to the support member by a sliding joint positioned at the distal end of the support member. The arm member can be movable along a first axis between retracted and extended positions. The sliding joint can include first and second bearing assemblies which are spaced apart a sufficient distance from each other for constraining portions of the arm member within the sliding joint. The proximal end of the arm member that overlaps with the support member outside of the sliding joint when in retracted positions can be capable of some unconstrained lateral movement relative to the first axis. A linear arm brake assembly can be coupled to the arm member for resisting linear motion of the arm member.

  • Patent number: 10513263
    Abstract: A method for controlling an engagement of a lock-up clutch (LUC) of a torque converter of a machine is disclosed. The method includes detecting a pedal tap of a pedal, wherein the pedal tap is detected when the pedal is depressed from a position corresponding to a pedal displacement less than a first threshold displacement to a position corresponding to a pedal displacement greater than a second threshold displacement, and then released to a position corresponding to a pedal displacement less than the first threshold displacement within a threshold time duration. The method further includes causing the LUC to move to the LUC unlocked position if the pedal tap is detected.

  • Patent number: 10046768
    Abstract: In order to reduce drivetrain component wear and tear, a machine monitors for an impending downshift and automatically slows the machine to a speed that keeps engine rpm below a target engine rpm before the downshift is completed. A controller in the machine determines the current speed of the machine and then slows the machine to a new speed associated with the target rpm in the new gear. The controller may simply apply the brakes to slow the machine to the new speed independently of the process of changing gears or may actively delay the gear change until the new speed is achieved.

  • Patent number: 9545925
    Abstract: A transmission system is disclosed for use with a machine. The transmission system may have a first clutch configured to transfer power in a first direction, a second clutch configured to transfer power in a second direction, a brake, and an interface device configured to generate a first signal indicative of a desire to shift power transfer directions. The transmission system may also have a controller configured to cause disengagement of the first clutch in response to the first signal, to cause the brake to apply a retarding torque to a traction device, and to determine an amount of the retarding torque being applied to the traction device. The controller may also be configured to selectively transfer the retarding torque to the second clutch when a capacity of the second clutch to provide retarding torque is about equal to the amount of the retarding torque being applied by the brake.

  • Patent number: 9514365
    Abstract: An integrated circuit has an image sensor to receive at least one image comprising a plurality of pixels from a camera comprising a lens, a buffer communicatively connected to the image sensor for storing values associated with the plurality of pixels, and a comparator communicately connected to the buffer to locate and identify the iris of a subject, in which locating and identifying the iris of the subject is based on a location of each pixel in a brightest pixel set. A method for locating and identifying an iris in an image includes capturing at least one image of an illuminated subject, determining a brightness value for each of the plurality of pixels, determining a location corresponding to each pixel in a brightest pixel set, and identifying the iris in the at least one image based on the location of each pixel in the brightest pixel set.

  • Patent number: 9505410
    Abstract: A transmission system is disclosed for use with a machine. The transmission system may have a first clutch to transfer power in a first direction, a second clutch to transfer power in a second direction, a brake, a sensor to generate a first signal indicative of speed, and an input device to generate a second signal indicative of a desire to shift directions. The transmission system may also have a controller to cause disengagement of the first directional clutch in response to the second signal, and to cause the brake to apply retarding torque. The controller may also be configured to determine an error value based on the second signal and a target transmission system speed, to selectively increase retarding torque when the error value increases, and to selectively transfer retarding torque to the second directional clutch when a value of the second signal is less than a threshold value.

  • Patent number: 8320729
    Abstract: A method and projection system for distorting a recording of a plurality of projected frames is disclosed, comprising a high frame rate display configured to impose a modulation on the projected frames at a frequency that is above the critical fusion frequency of the human visual system, wherein the modulation is of one of shutter width relative to shutter spacing, brightness, frame period, and pseudo-rastering. The high frame rate display may be a tonal display. The projection system may further include hardware for producing low frame rate imagery; an input buffer operatively coupled to said hardware for receiving one of a serial bit stream or blocks of data so as to store at least a predetermined portion of a frame; and a sub-frame generator operatively coupled to said input buffer and to said high frame rate tonal display for applying mathematical modulation techniques to said at least a predetermined portion of a frame.

  • Patent number: RE43647
    Abstract: A method and apparatus for preserving the dynamic range of a relatively high dynamic range information stream, illustratively a high resolution video signal, subjected to a relatively low dynamic range encoding and/or transport process(es). A relatively high dynamic range information stream is subjected to a segmentation and remapping process whereby each segment is remapped to the relatively low dynamic range appropriate to the encoding and/or transport process(es) utilized. An auxiliary information stream includes segment and associated remapping information such that the initial, relatively high dynamic range information stream may be recovered in a post-encoding (i.e. decoding) or post-transport (i.e., receiving) process.
