A control system includes a controller. The controller acquires current terrain data that indicates the current terrain to be worked. The controller decides on a target design terrain that is displaced vertically from the current terrain by referring to target displacement data. The target displacement data indicates the target displacement of a work implement according to the amount of movement from a work start position. The controller generates a command signal to move the work implement toward the target design terrain.

A crystal unit has a crystal blank provided with a pair of excitation electrodes and a pair of extension electrodes extended from the excitation electrodes, and a casing having a recess. A pair of connection terminals is formed on the bottom face of the recess. An inclined surface is formed at one end of a first principal surface of the crystal blank and the second principal surface of the crystal blank is flat-shaped. A conductive material is disposed between the connection terminals and the extension electrodes so that the extension electrodes are extended toward the end at which the inclined surface is formed and the second principal surface faces the mounting member, and the crystal blank is thereby held by the mounting member at the position of the end at which the extension electrodes are extended and electrically connected to the connection terminals.

A sheet processing apparatus which is capable of stabilizing a stop position of the sheet bundle, to thereby enable creation of a high finish quality product, and is compact in size and can be manufactured at low costs. Conveyance belts convey the sheet bundle to a flattening position. A pressing roller flattens the folded spine of the sheet bundle by pressing the folded spine. Clampers hold the sheet bundle such that the sheet bundle is not moved when flattening is performed. A CPU starts to stop driving of the conveyance belts when the sheet bundle is conveyed to a predetermined location upstream of the flattening position in the conveying direction of the sheet bundle, and stops the sheet bundle at the flattening position by holding the sheet bundle with the clampers before the conveyance of the sheet bundle is stopped.

Comparedwith the prior art, the multi-mode series-parallel mechanical arm based on the movement bifurcation mechanism has the advantages of being high in work efficiency, small in structure dimension, and high in overall stability.

The invention discloses a crowdsourcing service-oriented task allocation method and system for the Internet of Vehicles, and the method comprises the steps: obtaining a task estimation value accordingto task data returned by each vehicle in a task range; dividing quality grades according to the deviation between the task data returned by each vehicle and the task estimation value; setting a coverage range of the vehicles, and calculating a set of other vehicles covered by each vehicle based on the coverage range; selecting a task execution vehicle set with an approximately optimal data quality grade based on a set coverage method, wherein all task vehicles in the task execution vehicle set can realize full coverage of each vehicle in a task range; and sending the crowdsourcing task to allthe task vehicles. According to the invention, the data quality of the vehicle can be estimated in real time, and task allocation is performed on the request of the user according to the data qualitygrade and the vehicle relative position; and the data quality grade of the selected task vehicle is high, so that the purposes of reducing crowdsourcing answer redundancy and reducing system transmission overhead can be achieved.
