Abstract: Some implementations described herein provide techniques and apparatuses for a stacked semiconductor die package. The stacked semiconductor die package may include an upper semiconductor die package above a lower semiconductor die package. The stacked semiconductor die package includes one or more rows of pad structures located within a footprint of a semiconductor die of the lower semiconductor die package. The one or more rows of pad structures may be used to mount the upper semiconductor die package above the lower semiconductor die package. Relative to another stacked semiconductor die package including a row of dummy connection structures adjacent to the semiconductor die that may be used to mount the upper semiconductor die package, a size of the stacked semiconductor die package may be reduced.

Abstract: A head of a golf club is provided with a high coefficient of restitution. The head has a club head with an opening and a through hole opposite each other, a face panel securely mounted on the opening of the club head, a shaft securely mounted in the through hole of the club head, a shock-proof component mounted in the shaft, and an anti-impulse component mounted in the shaft and abutting the face panel. When hitting a golf, the face panel deforms concavely and shock waves are generated. Some of the shock waves are transmitted to the shaft via the through hole. With the shock-proof component, the shock waves transmitted via the through hole may be obstructed and not be absorbed by the anti-impulse component, which let all of the remaining shock waves on the face panel can be absorbed by the anti-impulse component thoroughly.

Abstract: A head of a golf club is provided with a high coefficient of restitution. The head has a club head, a shaft, and a buffer element. The club head has a face panel and an installing seat. The face panel is mounted on one side of the club head. The installing seat is formed on another side of the club head and has a through hole. The shaft is an elongated body, is mounted in the club head, and has a cavity and a mounting portion on two ends of the shaft. The mounting portion is securely mounted on the installing seat. The buffer element is a compressible and resilient body, and abuts the face panel. When hitting a golf, the face panel deforms concavely, and the impulse force is conserved by the buffer element so that the face panel may not split or break.

Abstract: A method for flexibly configuring default values of a network device and a network device using such flexible configuration method is described. First, it is determined whether the default values are obtained through a microprocessor interface or a memory interface. When it is determined that the default values are obtained through the memory interface, a header is received from a memory through the memory interface it is determined from the header whether any default value of the network device should be updated. If the network device should be updated, then at least one configuration instruction is fetched from the memory and the at least one configuration instruction is interpreted. A register default value of the default values is changed, corresponding to the interpreted at least one configuration instruction.

Abstract: A method for flexibly configuring default values of a network device through an EEPROM interface is disclosed. A header is received from an EEPROM through the EEPROM interface and it is determined from the header whether any default value of the network device should be updated, and if any, how many should be updated. At least one configuration instruction is fetched from the EEPROM when it is determined that the network device should be updated. The at least one configuration instruction is interpreted and a register default value of the default values corresponding to the interpreted at least one configuration instruction is changed.

Abstract: A model of a golf club head for casting includes a body having an upper plate with a small thickness. An ankle is formed at an end of the upper plate and at least one rib formed on the upper plate. A casting gate is formed beside the ankle. A casting pipe extends from the casting gate and around the body. Multiple ducts are connected between the casting pipe and the body. The at least one rib is connected to the ducts. Whereby, a duration of molten alloy to form the upper plate is short because the flow velocity of the alloy is quick. At the same time, the density of the upper plate is increased to reinforce its strength and improve its strike sound. Moreover, the overall size of the golf club head is small, such that a mold tree can include more investment molds to increase its capacity.
