Abstract: A planar magnetic component is arranged on a circuit board of a resonant converter, and the resonant converter includes a primary-side circuit and a secondary-side circuit. The planar magnetic component includes an inductor trace, an inductor iron core, and a current transformer trace. The inductor trace is arranged on the primary-side circuit and formed one layer board of the circuit board to serve as a resonant inductor coupled to the primary-side circuit. The inductor iron core includes a core pillar, and the core pillar penetrates a through hole of the circuit board, and the inductor trace surrounds the through hole. The current transformer trace is formed on the circuit board to serve as a current transformer coil coupled to the resonant inductor. The current transformer trace surrounds the through hole to form a common-core structure that shares the inductor iron core.

The planar magnetic component includes an inductor trace, a primary-side trace, a secondary-side trace, and an iron core assembly. The iron core assembly includes an inductor iron core and an iron core. The primary-side trace surrounds the first through hole in a first direction and surrounds the second through hole in a second direction to form an ?-shaped trace. The inductor trace is formed on the primary-side layer board and coupled to the primary-side trace, and two ends of the inductor trace form an input terminal and an output terminal of the planar magnetic component.

Abstract: A power supply unit supplies power to a load, and the power supply unit includes a power factor corrector, a DC conversion module, and an isolated conversion module. The power factor corrector is plugged into a first main circuit board and converts an AC power into a DC power. The DC conversion module is plugged into the first main circuit board and converts the DC power into a main power. The isolated conversion module includes a bus capacitor, the bus capacitor is coupled to the DC conversion module through a first power copper bar, and coupled to the power factor corrector through a second power copper bar. The first power copper bar and the second power copper bar are arranged on a side opposite to the first main circuit board, and are arranged in parallel with the first main circuit board.

Abstract: An electronic seal of the present invention includes a bolt. The bolt is used to mount on a door latch of a cargo and inserts into a shell. The shell is provided with a control circuit to actively send a warning signal as the bolt is moved. As such, the user of the electronic seal can be properly informed to prevent theft.

Abstract: A grid-based data clustering method comprises: a parameter setting step, a partition step, a searching step, a seed-classifying step, an extension step, and a termination step. Through the above-mentioned steps, data in a data set are disposed in a plurality of grids, and the grids are classified into dense grids and uncrowded grids for a cluster to extend from one of the dense grid to gradually combine data in other dense grids nearby. Consequently, convenience in parameter setting, efficiency and accuracy in data clustering, and performance in noise filtering are achieved.

Abstract: An anti-theft system includes a detecting device, a processing unit, and an alarm unit. The detecting device includes a first detecting unit that is operable so as to transmit a first signal, and a second detecting unit that transmits a second signal to the first detecting unit in response to the first signal. The processing unit verifies the second signal, and enables the first detecting unit to continue to transmit the first signal upon successful verification of the second signal. The alarm unit generates an alarm signal upon unsuccessful verification of the second signal. A container that is safeguarded by the anti-theft system is also disclosed.

Abstract: A temperature monitoring apparatus includes a casing, a detector, a sensor, a controller unit, and an indicator unit. The casing is formed with a hole therethrough. The detector is disposed in the casing, and detects extension of an object into the hole in the casing. The sensor is disposed in the casing, and is adapted to measure a temperature of the object extended into the hole in the casing. The controller unit is coupled to the detector and the sensor, and is operable so as to generate an actual temperature value with reference to the temperature measured by the sensor. The indicator unit is coupled to and controlled by the controller unit so as to provide an indication when the detector detects absence of the object in the hole in the casing.

Abstract: A temperature monitoring system includes first and second sensors, a microcontroller, a transmission unit, and a remote monitoring unit. The first sensor measures a skin temperature of a patient. The second sensor measures an ambient temperature of the patient. The microcontroller generates an actual temperature value with reference to the temperatures measured by the first and second sensors, and generates a warning signal when the actual temperature value generated thereby is within a predetermined temperature range. The transmission unit transmits the actual temperature value and the warning signal. The remote monitoring unit receives the actual temperature value and the warning signal, and records the time the warning signal was received thereby and location of the transmission unit.
