Abstract: A method for remotely updating firmware of a field programmable gate array (FPGA) includes: by a controller, transmitting a storing instruction and relaying an entry of configuration data received from a remote device to a processor of the FPGA; by the processor, performing an updating subtask to store a file segment recorded in the entry of configuration data in an update-storage area indicated by location information recorded in the entry of configuration data; by the controller, determining whether the processor has successfully completed the updating subtask, and when affirmative, enabling the remote device to transmit another entry of configuration data; and repeating the aforementioned steps.

Abstract: A golf club head includes a first shell portion, a second shell portion, and a reinforcing member. The first shell portion has a front striking face. The second shell portion complements with the first shell portion to form a unitary head body defining a hollow space. The second shell portion includes at least one carbon fiber reinforced plastic layer. The reinforcing member is embedded in the carbon fiber reinforced plastic layer, and is made of a material different from that of the carbon fiber reinforced plastic layer.

Abstract: A golf club head is mainly consisted of a metallic head housing having and a nonmetallic crown. The metallic head housing, which hollow and is open at a top thereof, has a face, a sole, a rear, a toe and a heel. At the toe and the heel of the head housing is a gap respectively. The crown coupled to the top of the head housing, wherein the crown has two arms coupled to the toe and the heel of the head housing respectively to shield the gaps.
