Abstract:
An electronic device includes a body, a cover coupled to the body, and a sliding mechanism. The sliding mechanism includes a rotating component, a first locking component, and a second locking component. When the second locking component moves to a locked position, the second locking component engages with the first locking component to lock the cover to the body. When the second locking component moves to an unlocked position, the first locking component disengages from the second locking component, to allow the rotating component to rotatably drive the cover to be opened.
Abstract:
A device is disclosed for switching an electrical switch on and off, with a drive shaft and with an output shaft. In at least one embodiment, the drive shaft and the output shaft running transversely with respect to one another and interacting in such a way that a rotation of the drive shaft entails a rotation of the output shaft, the drive shaft being rotatable between an ON position and an OFF position, and the output shaft being rotatable correspondingly thereto between a switch-on position and a switch-off position. In at least one embodiment, the output shaft is connected to the switch which can be switched on into the switch-on position as a result of the rotation of the output shaft and can be switched off into the switch-off position by rotation. In order to achieve a simple set-up and a force-saving actuation of the switch, it is proposed, in at least one embodiment, that the drive shaft and the output shaft be connected to one another via a displaceable sliding element which, during the rotation of the drive shaft, is displaced, and the output shaft is rotated by the sliding element in the course of displacement.
Abstract:
An electrical device includes a thermistor and at least two electrodes electrically connected to the thermistor and to which a source of electrical power is applied to cause current to flow through the thermistor. The thermistor may be a composite and includes a polymer material; and a plurality of conductive carbon nanotubes distributed in the polymer material. The electrical device employed with the thermistor performs not only PTC property, but also NTC property. Moreover, the method for fabricating the electrical device is also simple and easy to carry out because of the simple process.
Abstract:
Dental caries is a polymicrobial infectious disease. Of the hundreds of bacteria present in the biofilms coating teeth, the Streptococcus mutans (S. mutans) remain strongly linked to caries and dental disease. Streptococcus sanguinis (S. sanguinis) may serve a protective or antagonistic role against the cariogenic bacterium S. mutans. In the present invention, exemplary sets of species-specific PCR primers are provided for the identification and quantification of S. mutans and of S. sanguinis in clinical samples, including the simultaneous and sensitive analysis of both bacterial species. Assays, kits and methods for determining the presence and amount of S. mutans and/or S. sanguinis are provided. Oligonucleotide probes and primers for use in the assays, kits and methods are described. Assays and methods for determining and evaluating an individual's oral bacteria, risk for caries, and effects of prevention and treatment modalities, are provided.
Abstract:
A connecting structure received in a main device for connecting an auxiliary apparatus. The connecting structure includes a retracting part formed on a bottom board of the main device and close to a sidewall of the main device and a clamping part. The clamping part is pivotablly mounted on the bottom board and pivotally connected to the retracting part. The retracting part drives the clamping part to extend out of the main device via an opening defined on the sidewall for connecting the auxiliary apparatus when the auxiliary apparatus needs to be mounted on the main device. The retracting part retracts the clamping part into the main device when the auxiliary apparatus is unmounted from the main device.
Abstract:
A portable electronic device includes a main body, a display and a distance measuring device. The distance measuring device includes a first distance measuring member and a second distance measuring member. The first distance measuring member includes a first signal emitting/receiving module and an arithmetic module. The second distance measuring member includes a second signal emitting/receiving module and a control module. The first signal emitting/receiving module is for receiving an alignment signal, emitting a measuring signal, and receiving a feedback of a measuring signal. The arithmetic module is for calculating the distance between the first distance measuring member and the second distance measuring member. The distance is displayed. The second signal emitting/receiving module is for emitting the alignment signal, receiving the measuring signal, and emitting the feedback of the measuring signal. The present disclosure further provides a distance measuring method for a device.
Abstract:
A keyboard includes a main keypad, a numerical keypad, a processor, and a detector. In an input mode, the processor processes input information of the main keypad or input information of the numerical keypad and outputs the processed input information of the main keypad or the processed input information of the numerical keypad to a computer. In a calculator mode, the processor performs a numerical calculation upon the input information of the numerical keypad. The detector detects operation states of the computer and the processor is controlled to switch between the input mode and the calculator mode according to the detected operation states.
Abstract:
