Abstract:
A lamp clamping and electrically connecting device includes a base, two flexible portions and two protrusions. The flexible portions are interspaced to be disposed on the base. The protrusions are correspondingly disposed on the inner sides of the flexible portions. In a natural state, the gap between the protrusions is smaller than the diameter of an electrode end of a lamp. When the electrode end is moved towards the base in the gap between the protrusions, the electrode end presses the protrusions so that the flexible portions swing outwardly. When the electrode end touches the base, the protrusions are restored to the natural state, so that the protrusions and the base clamp the electrode end, and that the electrode end is electrically connected to the device.
Abstract:
A temperature sensor, which comprises a temperature-dependent element, a comparator unit, first/second capacitors and first/second switching capacitors, is provided. The temperature-dependent element has an input terminal selectively coupled to one of a first current source and a second current source, and has an output terminal. The comparator unit comprises a comparator and first/second feedback capacitors. One end of the first switching capacitor is coupled to the first comparator input terminal, and another end of the first switching capacitor is selectively coupled to one of two different voltages. One end of the second switching capacitor is coupled to the second comparator input terminal, and another end of the second switching capacitor is selectively coupled to one of two different voltages.
Abstract:
A temperature sensing apparatus for a liquid crystal display device is disclosed. The apparatus can measure the device temperature without the existence of a conventional PN junction. The temperature sensing apparatus comprises at least one thin-film transistor (TFT) cell, a variable current source, a buffer and a sensing circuit. Each TFT cell has its respective drain and gate coupled together and a source coupled to a ground The variable current source is coupled to the drain of the TFT cell. The buffer has an input coupled to the drain of the TFT cell. The sensing circuit has an input coupled to an output of the buffer and an output to produce a voltage output signal. The temperature of the TFT cell is determined by inputting two currents at a sub-saturation region of the TFT cell and measuring voltage output signal difference.

Abstract:
A fingerprint acquisition apparatus including a plurality of sensing units is provided. The fingerprint acquisition apparatus is used for sensing the ridge portion and the valley portion of a fingerprint. Each sensing unit includes a built-in capacitor. There is an inducing capacitance generated between each of the sensing units and the fingerprint while the fingerprint touches each of the sensing units. The fingerprint acquisition apparatus of the invention generates a fingerprint pattern by detecting the difference of inducing capacitances between the ridge portion of the fingerprint and the valley portion of the fingerprint.

Abstract:
This specification discloses a non-volatile static random access memory (SRAM) cell with the feature of keeping data even after the power is turned off. It includes a static random access unit and a non-volatile memory unit. Therefore, it has the random access property of the SRAM normally. After the power is turned off, it can store data in the non-volatile memory unit, so that the data can be automatically restored to the static random access unit from the non-volatile memory unit when the power is turned on.
