Abstract: In a method of measuring group delay (Tgd) of a device under test, an analog input signal having a predetermined period (T) is provided to the device under test so as to obtain a delayed output signal from the device under test. A phase difference is detected between first and second digital signals converted from the analog input signal and the delayed output signal, respectively. A current (I) corresponding to the phase difference flows through a circuit having a predetermined resistance (R) so as to result in a potential difference (ΔV). As such, the group delay (Tgd) of the device under test is determined as a function of the predetermined period (T), the current (I), the predetermined resistance (R), and the potential difference (ΔV). An apparatus for measuring the group delay (Tgd) of the device under test is also disclosed.

Abstract: A linear motion apparatus has a linear track, a slider and two sliding-assistant units for a linear motion apparatus. The sliding-assistant units for a linear motion apparatus is mounted between the track and the slider to enhance ease of movement between the track and the slider, and each sliding-assistant unit has two roller rings to receive rollers. The roller rings are elongated rectangular rings, are selectively mounted oppositely crossly around each other. Each roller ring is designed with reduced components to make manufacturing and assembling the sliding-assistant unit easier. Moreover, the roller ring is designed as one unity so no seam will be formed due to assembling two different pieces, such that ensures contact between the rollers and the roller ring smooth.

Abstract: A rolling element chain is applied to retain and arrange multiple rollers at intervals in a line and has a belt assembly and multiple clamping assemblies. The rollers are cylinders mounted parallelly in the rolling element chain. The belt assembly is resilient and has two parallel bars. The clamping assemblies are formed in pairs between the parallel bars to form multiple roller holes on the belt assembly and each clamping assembly has multiple clamping protrusions. The clamping protrusions of each clamping assembly are formed in a line between the parallel bars and alternately protrude oppositely away from the belt assembly and together hold one corresponding roller in the belt assembly. Each clamping protrusion has a roller surface and at least one apex. The at least one apex is formed on and protrudes from the roller surface, thereby, reduces contact area between the clamping protrusions and the rollers.

Abstract: A measurable guide actuator is used to integrate a driving mechanism, a guide mechanism, and a position measuring member so as to form an integral simplifying construction, thereby facilitating the usage and thereby reducing consumption of material. The measurable guide actuator of the present invention uses a U-shaped guide track to function as the guide mechanism. The driving mechanism uses a screw or a belt. The position measuring member includes a ruler body mounted in the guide mechanism, and a reading head sealed in the sliding table to slide therewith so that the position measuring member can be used to measure the displacement position values.
