Abstract:
An electronic device holder used to be fixed on a moving carrier for holding an electronic device is provided. The electronic device holder includes a holder, a fixing element, a moving unit and at least one first connector. The fixing element fixed on the holder has a first limiting structure. The moving unit disposed between the holder and the fixing element moves relative to the holder. The moving unit has a second limiting structure used to lock with the first limiting structure for fixing the moving unit on a lock position or an open position. The first connector is disposed on the moving unit and used to connect with a second connector when the moving unit is located on the lock position relative to the holder. The electronic device holder integrates functions of holding and charging for the electronic device.
Abstract:
A power socket includes a socket main body, a front cover and a safety gate mechanism. The front cover has two openings. The safety gate mechanism includes a casing and a safety gate. The casing located between the socket main body and the front cover has two inserted holes and a protrusion. The inserted holes are aligned with the openings. The safety gate slidably disposed at the casing is dislocated from the protrusion. When the safety gate is at a first position, the safety gate blocks the inserted holes, and two terminals of a plug push the safety gate through the two openings to make the safety gate slide to expose the inserted holes. When an object pushes the safety gate through one of the openings, the safety gate rotates to drive a part of the safety gate to be aligned with the protrusion to avoid exposing the inserted holes.
Abstract:
A method for updating an operating system (OS) and a handheld electronic apparatus are provided. In the method, when an updating instruction is received by the handheld electronic apparatus, an updating procedure is executed by an updating module of firmware in the handheld electronic apparatus. The updating procedure includes steps of backing up item data in a first storage area to a second storage area, updating the OS that is installed on the first storage area, and restoring the item data from the second storage area to the first storage area after the OS is completely updated.
Abstract:
An antenna-integrated isolation cover comprises a main body, a first antenna unit, and a plurality of holes. The main body has a first side. The first antenna unit is disposed on the first side of the main body. The holes are disposed to the main body. An electronic apparatus using the antenna-integrated isolation cover is also disclosed.
Abstract:
A flexible terminal includes two flexible parts and a connecting part. Each flexible part includes an outer segment having a first end and a second end, a first bent segment having one end coupled to the first end, and an inner segment coupled to the other end of the first bent segment. The connecting part is coupled to two second ends of the outer segments. Due to the flexible arrangement of the flexible parts, the flexible parts can be flexibly deformed to fit the dimension of a fastening element. In addition, the inner segments of the flexible terminal can clip the fastening element so as to avoid the relative displacement of the flexible terminal and the fastening element during the operation.
Abstract:
A method of examining a test apparatus for a wireless network device is performed with a computer apparatus, a vector signal analyzer, and a vector signal generator and includes a signal receiving/transmitting step and a result outputting step. A transmitting signal test value and a receiving signal test value of the wireless network device test apparatus are measured by transmitting a reference signal of the vector signal generator and performing a receiving procedure of the wireless network device test apparatus and by transmitting a test signal of the wireless network device test apparatus and performing a receiving procedure of the vector signal analyzer, respectively. After the computer apparatus outputs an error of the wireless network device test apparatus and a comparison table of standard tolerance. Accordingly, the method enables self-testing to be performed and thereby dispenses with high fees charged by examination institutions for examining the test apparatus.
Abstract:
A power supply mode switching circuit and method switch between power supply modes of a power supply device dynamically based on an operating current required for operation of an electronic product, such that the power supply device supplies a supplying current corresponding to the operating current. The circuit comprises a sampling unit, an amplifying unit, a comparing unit. The circuit is disposed between the power supply device and the electronic product, samples the supplying current from the power supply device with the sampling unit, and converts the supplying current into a sampling voltage. The amplifying unit converts the sampling voltage into an amplifying voltage by voltage amplification and outputs the amplifying voltage to the comparing unit. After comparing the voltage level of a reference voltage and that of the amplifying voltage, the comparing unit generates a control signal for switching the power supple modes of the power supply device.
Abstract:
A HomePlug with a changeable top case structure includes a casing and a socket assembly. The casing has a first coupling portion therein and has an opening. The socket assembly has a second coupling portion for coupling with the first coupling portion, such that the socket assembly corresponds in position to the opening and thereby is coupled to the casing from inside and exposed from the opening. The HomePlug with a changeable top case structure is effective in dispensing with redesign and the manufacturing of a casing in its entirety, cutting die and material costs, enhancing ease of product design, and increasing assembly universality.
Abstract:
A downstream power calibration method comprises the following procedures. First, select base sampling frequencies and sampling power levels, thereby generating base sampling signals. Next, input base sampling signals into a modem such that obtaining each sum of the feedback signals responding to the tuner and the IF amplifier of the modem by the modem chip corresponding each said base sampling signal, thereby setting up a sampling data table. Third, repeat the procedure mention above for a plurality of modems to get a plurality of sampling data tables respectively, and then obtain a mean data table. Fourth, select spot frequencies and spot power levels from the base sampling frequencies and the base sampling power levels to generate spot sampling signals. Thereafter, input the spot sampling signals into a cable modem and set up a skeleton data table. Finally, expand skeleton data table and obtain an individual default data table for the modem, thereby providing the basis of the calculation of power levels when the cable modem is receiving downstream signals.
Abstract:
A composite fixed bracket includes a device-end bracket, a fixed-end bracket and an auxiliary fixing bracket. The device-end bracket has first rotating-connecting parts and device connection parts connecting an electronic device. The fixed-end bracket has second rotating-connecting parts, first sliding-connecting parts and hole parts. The first and the second rotating-connecting parts are relatively rotated to fit and connect to each other for fixing the fixed-end and device-end brackets. The fixed-end bracket is located between the device-end bracket and the auxiliary fixing bracket. The auxiliary fixing bracket includes two fixing units, and each fixing unit includes two second sliding-connecting parts, an engaging part and a ring-fixing part. The second sliding-connecting parts are connected to the first sliding-connecting parts respectively, so the fixing units are slidably connected to the fixed-end bracket.
