Abstract:
A vehicle includes: a chassis; a driving unit including a mounting seat pivoted to the chassis, a driving member mounted on the mounting seat, and two driving wheels mounted rotatably on the mounting seat and driven by the driving member; two front wheel units, each including a front lever having first and second ends and pivoted to the chassis, a front wheeled member connected to the first end, and a first cushioning member pivoted to the second end and the mounting seat for urging the front lever to rotate; and two rear wheel units, each including a rear lever having first and second ends and pivoted to the chassis, a rear wheeled member connected to the first end, a second cushioning member pivoted to the first end and the mounting seat, and a linkage pivoted to the second end of the rear lever and the mounting seat.
Abstract:
The scheme for detecting the plug-in status by using single bit generated by a network with serial resistors, comprising a plurality of jacks having a spring switch, wherein the number of the plurality of jacks can be selected depending on the demand and a plurality of resistors followed the spring switch and connected in serial. Output voltage-generating resistor is coupled to the plurality of resistors in parallel to obtain the output voltage, thereby determining the plug-in status. Wherein the plurality of jacks and the plurality of resistors construct a multi-jack network, a first terminal of the multi-jack network refers to a common node between a first connecting terminals of the spring switch of the plurality of jacks and a first resistor of the plurality of resistors, the first terminal being coupled to a first reference voltage, a second terminal of the multi-Jack network refers to a common node between the second connecting terminals of the last jack and the last resistor. Wherein the output voltage-generating resistor is coupled between the second terminal of the multi-jack network and a second reference voltage.
Abstract:
A transistor includes a notched fin covered under a shallow trench isolation layer. One or more notch may be used, the size of which may vary along a lateral direction of the fin. In some embodiments, The notch is formed using anisotropic wet etching that is selective according to silicon orientation. Example wet etchants are tetramethylammonium hydroxide (TMAH) or potassium hydroxide (KOH).
Abstract:
A lighting device has a light-bar mount and multiple light bars. The light-bar mount is integrally formed from a board. The light bars are mounted on the light-bar mount and each light bar has a heat sink, a circuit board and multiple high-power LED modules. The heat sink is detachably mounted in the light-bar mount. The circuit board is mounted in the heat sink. The high-power LED modules are mounted on the heat sink and electrically connected to the circuit board for providing outward illumination.
Abstract:
System of multi-channel shared resistor-string digital-to-analog converters comprises a time-sharing interpolator converting the multi-channel digital audio input at low sample rate to the multi-channel digital audio output at high sample rate, a time-sharing sigma-delta modulator modulating the multi-channel digital audio input with a long sample wordlength from the interpolator to be a multi-channel digital audio output with a shorter sample wordlength, multi-channel shared resistor-string digital-to-analog converters converting the multi-channel digital audio input to be a multi-channel staircase analog signal output, and one low-order RC filter for each channel further attenuating the out-of-band noise in the analog staircase analog output, especially the high-frequency residue images.
