Abstract: A pulse ablation catheter for treating pulmonary arterial hypertension includes an ablation catheter part and an energy platform, where the ablation catheter part includes a movable outer sheath tube, an ablation catheter, a functional guide core, a pulse ablation part and an operating part; the operating part controls the pulse ablation part to slide axially on the functional guide core in a center of the ablation catheter, and controls strip-shaped arches in a middle of the pulse ablation part to arch or fold in a circumferential direction so as to perform pulse ablation through pulse electrode sheets and the energy platform. The pulse ablation catheter for treating pulmonary arterial hypertension of the application performs pulse ablation through the pulse ablation catheter with controllable frequency and ablation end shape to treat pulmonary arterial hypertension.

Abstract: A refrigerator cooling system, comprising a pipe forming a loop and, sequentially provided on the pipe, a compressor, a condenser, a refrigerant amount regulator, a capillary tube, and an evaporator. The refrigerant amount regulator comprises a storage device and an adjustor provided within the storage device. The storage device is provided therein with a storage cavity for holding a refrigerant. The storage device is provided with an opening for the storage cavity to be in communication with the pipe. The adjustor comprises a sealer used for opening or closing the opening.

Abstract: Adjusting an operating frequency of a CPU includes setting the operating frequency for a current operating cycle based on a CPU load in a prior operating cycle and a target CPU load. A current CPU load associated with the current processing cycle is detected. The CPU operating frequency is adjusted to a new operating frequency based on a difference between the target CPU load and the current CPU load. The operating frequency is adjusted based on minimizing the difference between the target CPU load and the detected load. A CPU load error is determined based on the current CPU load and the target CPU load. The target CPU load is adjusted based on the determined CPU load error and a threshold load error. A prediction is generated on whether to perform a new adjustment of the operating frequency of the CPU prior to expiration of a threshold time duration.

Abstract: A computer-implemented method classifies a packet received from a network. The method comprises receiving the packet having header information and a rule-set that indicates a plurality of actions to perform on the packet. A geometric representation of the rule-set is constructed having a plurality of dimensions and rule boundaries. At least one rule boundary and dimension of the geometric representation is split to form a search structure having a plurality of nodes. Each node in the plurality of nodes is constrained to a predetermined memory threshold. The search structure is searched using the header information to obtain a rule in the rule-set that indicates an action to take on the packet.
