Abstract: A safety syringe assembly and a replaceable base unit are disclosed. The replaceable base unit of the present invention includes a base portion, a needle cover and a disengagement actuator. The base portion is configured to detachably connect with a syringe holder and has a through-hole structure, which is used to connect with an external needle. The needle cover's proximal end is connected with the base portion to allow the needle cover to move with respect to the base portion, enabling it to contain and cover the syringe needle. The disengagement actuator is configured on the base portion and disengages the base portion from the syringe holder in pressing mode.

Abstract: A method of calculating a transport block size in an HSPA receiver of a communication system is provided. After decomposing an exponential function Pk into a plurality of constant vectors, the invention needs only little memory space and executes few continued multiplication operations to obtain a correct transport block size, thereby increasing efficiency and reducing calculation complexity.

Abstract: An encoding module for a cursor input device includes an optical encoder roller rotatable relative a roller supporting frame about a horizontal axis, a base member having the roller supporting frame on the base member such that the roller supporting frame is movable vertically toward and away from the base member, a switch mounted on the base member and disposed below a switch actuating block of the roller supporting frame such that downward movement of the roller supporting frame relative to the base member will enable the switch actuating block to engage the switch. The roller engages intermittently the roller supporting frame to permit rotation of the roller relative to the roller supporting frame in steps.
