A built-in self-test mechanism for an interface chip. During a loopback test procedure, a transmission terminal of the interface chip is coupled back to the interface chip by a reception terminal of the interface chip and a loopback test circuit within the interface chip generates a test sequence which includes a synchronization section and a section of repeated test code. The test sequence is scrambled by a scrambler and then is transmitted via the transmission terminal and looped back to the reception terminal. The signal looped back to the reception terminal is processed by an equalizer and descrambled by a descrambler to be further checked by the loopback test circuit for determining whether the interface chip is functioning normally. The dynamically-changed keys used in the scrambler and the descrambler are synchronized according to the synchronization section. The equalizer is optimized by the scrambled section of repeated test code.

Interface chip and test method therefor

A locking structure for a replaceable toothbrush includes a locking plate and a brush head. An end portion of the locking plate includes elastic locking hooks, and the elastic locking hooks are arranged on the supporting platform. The brush head is replaceably installed on the supporting platform, and the brush head includes a brush head base and brush bristles. The brush head base includes a substrate and a surrounding plate extended from an edge of the substrate toward one side thereof, and the surrounding plate includes a locking slot for the elastic locking hook to lock thereon. The brush bristles are disposed on the substrate and extended away from the surrounding plate. Accordingly, the release of the locking and retrieval for disengagement of the brush head base are facilitated and the brush head base is firmly installed on the supporting platform.

Locking structure and brush head thereof for replaceable toothbrush

A toothbrush with a front-push replaceable brush head includes a handle portion, a handle front section connected to the handle portion and having a supporting platform, a front-push mechanism including a pulling arm pivotally attached to the handle portion and push and locking plates stacked together penetrating the handle front section, the pulling arm driving the push and locking plates to move; a brush head replaceably installed on the supporting platform, the locking plate locked onto the brush head and handle front section; the pulling arm is pulled and rotated to move the locking and push plates toward the brush head and to release the locking plate, handle front section and brush head from locking while the push plate pushing the brush head away from the supporting platform. Therefore, the release of locking and disengagement of the brush head are achieved simultaneously to facilitate operations of the toothbrush.

Toothbrush with front-push replaceable brush head

An interface chip capable of accurate link detection. The interface chip mounted on a first electronic device has a link layer and a physical layer. The link layer outputs data to be transformed and transmitted to a second electronic device by the physical layer. The data transmitted from the second electronic device is received and transformed by the physical layer and then conveyed to the link layer. The link layer includes a state machine, which performs a state modification on the first electronic device to rescue the second electronic device from a trapped state for confirming a link between the first and second electronic devices, wherein data output by the link layer and transformed and transmitted to the second electronic device by the physical layer is changed according to the state modification.
