Weight verification and tare process for scale
An electronic scale performs a post-weighing calibration in which the user steps on the scale, and the scale provides an estimated weight based on the scale's stored tare weight determined after the previous weighing performed by the scale. The person steps off of the scale while the estimated weight is displayed, and the scale automatically performs the calibration process to determine the scale's tare weight and verifies the weight. The estimated weight is shown with an orange ellipsis, and the verified weight is shown with a green checkmark. The scale compares the stored tare weight with the new tare weight, and if the difference between the stored tare weight and the new tare weight is within a variation threshold, the scale identifies the weight as being verified. If the difference exceeds the variation threshold, the scale recalculates the weight, displays the corrected weight, and produces a tone as an alert. |

When the compressor needs to be turned on and then to be turned off, an air volume of the draught fan is adjusted, and the flowing amounts of the bypasses and a main circuit are simultaneously adjusted until the air valves that control a flowing amount of an evaporator are all closed and the air valves of the bypasses are all opened. Adjustment of the air valves and state switching of the compressor are made at the same time, so that the flowing amount flowing through a heater to a chamber is ensured to always remain unchanged. |

Method for identifying geological and drilling patterns in a unidimensional space via periodic orthogonal functions applied to drilling parameter data
The present invention relates to a technique for identifying geological and drilling patterns by analyzing data from drilling parameters, using periodic orthogonal functions applied to such data. The use of averages to convert time data to depth data acts as a low-pass filter, attenuating the textural information from the torque data.

Reinforcement and protection braces for mounting structures of vehicle steering knuckle lower control arms
The present invention provides reinforcing braces for attachment to factory-supplied chassis mounts for the lower control arms of steering knuckles of vehicles to reinforce and shield the mounts from objects below the vehicle encountered when traveling through rugged terrain. Each brace includes a pair of parallel sturdy metal flanges that are attached to a sturdy metal lower base plate. Each flange is designed to be attached to one of the flanges of the factory-supplied chassis mounts, and has an opening therein for receiving mounting hardware, and an open section for engagement with camber adjustment structures. The sturdy base plates provide a lower shield to protect the chassis and mounting hardware from damage from contact with large objects encountered below the vehicle. The front base plate may also include an elongated front shield for deflecting large objects as the vehicle moves forward. |

Control assembly for zero turn device
A control assembly for use with a vehicle having a pivot arm for controlling output of the vehicle includes a bracket, a yoke attached to the pivot arm, and a shaft engaged to the yoke and extending into the bracket. The pivot arm is rotatable about a first axis of rotation between a neutral position and a plurality of forward positions and a plurality of reverse positions. When in the neutral position, the pivot arm may also rotate about a second axis of rotation between an operative position and a stopped position, and a switch may be engaged when the pivot arm is rotated to the stopped position. A return to neutral assembly may provide a return force to the pivot arm when it is rotated about the first axis of rotation away from the neutral position. |
