Abstract: A power battery pack includes: a pack body; a plurality of cells, disposed in the pack body; the cell having a length L0, a width H0, and a thickness D0, where at least one cell meets: L0>H0?D0, a length direction of the cell is arranged along a width direction of a vehicle body of the electric vehicle, and in the width direction of the electric vehicle, the length L0 of the cell and a size W of the vehicle body of the electric vehicle in the width direction meet: 46%?L0/W?76%; or at least one cell meets: L0>H0?D0, a length direction of the cell is arranged along a length direction of a vehicle body of the electric vehicle, and in the length direction of the electric vehicle, the length L0 of the cell and a size X of the vehicle body of the electric vehicle in the length direction meet: 40%?L0/W?76%.

Abstract: A multi-procedure integrated automatic production line for hard alloy blades under robot control is provided. The production line includes a rail-guided robot. A cutter passivation device and a blade cleaning and drying device are arranged on one side of the rail-guided robot. A blade-coating transfer table, a blade coating device, a blade boxing transfer table, a blade-tooling dismounting device and a blade boxing device are sequentially arranged on another side of the rail-guided robot. The blade-tooling dismounting device is arranged on one side of the blade boxing transfer table. The production line further includes squirrel-cage toolings for carrying the blades. The squirrel-cage tooling that are loaded with the blades can run among the cutter passivation device, the blade cleaning and drying device, the blade-coating transfer table and the blade boxing transfer table. The blades after being treated through the blade-tooling dismounting device are sent to the blade boxing device.

Abstract: Balanced programmable delay element that has a variable incremental delay. A first inverter is provided that has a first electrode for receiving an input signal, a second electrode, a third electrode, and a fourth electrode for providing an output signal and that has a propagation delay that is dependent on a first current. A second inverter is provided that has a first electrode coupled to the fourth electrode of the first inverter for receiving the output signal of the first inverter, a second electrode, a third electrode, and a fourth electrode for providing an output signal and that has a propagation delay that is dependent on a second current. A current switch is coupled to the first inverter, the second inverter, receives at least two control signals, and responsive thereto, selectively varies the incremental delay of the delay element.

Abstract: A balanced programmable delay element that has a variable incremental delay. A first inverter is provided that has a first electrode for receiving an input signal, a second electrode, a third electrode, and a fourth electrode for providing an output signal. The second electrode and the third electrode form a first current path, and the first inverter has a propagation delay that is dependent on the current through the first current path. A second inverter is provided that has a first electrode coupled to the fourth electrode of the first inverter for receiving the output signal of the first inverter, a second electrode, a third electrode, and a fourth electrode for providing an output signal. The second electrode and the third electrode form a second current path, and the second inverter has a propagation delay that is dependent on the current through the second current path.
