An electrical connector includes a housing member and a number of contacts attached to the housing member. The contacts include a number of first contacts and second contacts arranged side by side along a transverse direction, respectively. The second contacts include a first pair of differential contacts, a second pair of differential contacts and a grounding contact disposed therebetween. At the mounting end of the electrical connector, a space between the grounding contact and the differential contact of each pair most adjacent to the grounding contact is much bigger than any internal space between the differential contacts of each the first or the second pair. As a result, a rear wall of the housing member can provide adequate area for easily mounting a fiber optical lens.

A deglitch circuit including signal transmission units is provided. The signal transmission units are connected in serial to form a signal transmission unit string, and a first signal transmission unit of the signal transmission unit string receives a digital signal. Each signal transmission unit includes a first switch, a first delay circuit and a second switch. First and second terminals of the first switch are coupled to a previous signal transmission unit of the signal transmission unit string and an input terminal of the first delay circuit, respectively. The second switch is coupled between an output terminal of the first delay circuit and a first voltage. When the digital signal has a first logic state, the first switch is turned off, and the second switch is turned on. When the digital signal has a second logic state, the first switch is turned on, and the second switch is turned off.

An input apparatus, an input method and an electronic apparatus are provided. The input apparatus includes a signal generating module and a processing module. The signal generating module generates a plurality of input signals by executing multi-direction operations. The processing module receives two signals of the input signals which are successively generated by the signal generating module, thus generating a control signal. The control signal corresponds to one of a plurality of characters. Therefore, the input apparatus can be more conveniently used by users to input characters by executing multi-direction operations.

A reference circuit for providing a precision voltage and a precision current includes a bandgap voltage reference circuit, a positive temperature coefficient calibrating circuit, a threshold voltage superposing circuit and precision current generator interconnected in cascade. From the bandgap voltage reference circuit, a bandgap voltage is outputted as the precision voltage, and a PTAT current is outputted to the positive temperature coefficient calibrating circuit along with the bandgap voltage for generating a PTAT voltage. In response to the PTAT voltage from the positive temperature coefficient calibrating circuit, the threshold voltage superposing circuit generates a first voltage which is equal to the PTAT voltage plus a threshold voltage. Then the precision current generator outputs a reference current as the precision current in response to the first voltage.

An LED lamp (100) includes a cover (10) having two concave reflective surfaces (121, 123), a base (21) disposing over the cover, a lens (40) locating in a middle of the base, and two LEDs (30) mounted on a bottom surface of the base. The lens and the LEDs face the reflective surfaces of the cover. The reflective surfaces each are a part of an ellipsoid. The reflective surfaces share a common focus O within an area of the lens. The LEDs are respectively located at other two focuses M1, M2 of the reflective surfaces. Light rays generated by the at least two LEDs are directed to the reflective surfaces, then reflected towards the lens of the base, and finally reach an outside of the LED lamp through the lens.

An extension to USB includes an insulative tongue portion and a number of contacts held in the insulative tongue portion. The contacts have four conductive contacts and a plurality of differential contacts for transferring differential signals located behind/forward the four standard USB contacts along a front-to-rear direction. The four conductive contacts are adapted for USB 2.0 protocol and the plurality of differential contacts are adapted for non-USB 2.0 protocol. The extension to USB is capable of mating with a complementary standard USB 2.0 connector and a non-USB 2.0 connector, alternatively.
