Abstract:
A femtocell in electronic communication with different user equipments includes a setting unit, a subscriber identity module (SIM), a signal processing unit and a monitoring unit. The setting unit sets and establishes a monitoring area to monitor all items of user equipment. The SIM stores a whitelist which includes a plurality of identification (ID) codes corresponding to a plurality of items of user equipment. When the ID code of an item of user equipment is not within the whitelist of the SIM, the signal processing unit controls the monitoring unit to establish and monitor the position of the user equipment to determine whether the user equipment is within the predetermined monitoring area.
Abstract:
A counting device for distance measuring wheel includes a housing, a transmission assembly, a counter wheel assembly, and a reset control assembly. An elastic support unit of the reset control assembly is arranged at the side of each of the transmission assembly and the counter wheel assembly so that the relative positions among the transmission assembly, the counter wheel assembly, and the reset control assembly arranged inside the housing are changed and the size of the counter wheel assembly may become larger while the size of the housing is not changed.
Abstract:
A resin composition for composite material parts includes a main agent composed of an epoxy resin and a reactive diluent, and a curing agent. The reactive diluent, which is monomer or oligomer of acrylate or methacrylate having one or more vinyl (unsaturated double bond) functional groups and has low viscosity at room temperature, is used in an amount of 5 to 30 parts by weight based on 100 parts by weight of the main agent such that the main agent has a viscosity of 700 to 3000 cps at 25° C. The resin composition of the present invention is very suitable for being used to manufacture composite material parts used in wind blade, boat, automobile and aircraft by the manufacturing process such as vacuum infusion and hand lay-up vacuum assisted resin infusion process.
Abstract:
A breakdown precautionary system of a semiconductor equipment includes a semiconductor equipment with a coil heater, at least a voltage/current detector, and an alarm system. The voltage/current detector detects the voltage and current of the coil heater at the same time. An alarm system will send an alarm signal and initiate an interlock safety measure of the semiconductor equipment when the detected current of the coil heater is 0 ampere.
