Abstract: A total-sky lightning event observation system and method may include a photographing device, a housing, a temperature control device, a light shielding device, a control module, a power supply module, a corona current sensor, a data acquisition device, a GPS antenna, a GPS timing module and a processing unit. The photographing device can capture total-sky digital images and transmit the images directly to the processing unit. The processing unit consecutively acquire corona current via the data acquisition device and judges whether there exists thunderstorm activity within the observed range; if there exists thunderstorm activity, the light shielding device is opened so as to enter a lightning observation mode, and the light shielding device is closed after the observation is finished so as to protect the photographing device in non-thunderstorm weather.

Abstract: A photodiode includes an opening over an active photodiode region so that a top passivation layer and interlayer dielectric layers (ILDs) do not affect the spectral response of the photodiode. A dielectric reflective optical coating filter, which includes a plurality of dielectric layers, fills at least a portion of the opening and thereby covers the active photodiode region, to shape a spectral response of the photodiode. Alternatively, the dielectric reflective optical coating filter is formed prior to the opening, and the opening is formed by removing a top passivation coating and ILDs to expose the dielectric reflective optical coating filter.

Abstract: A photodiode includes a substrate having a first semiconductor type surface region on at least a portion thereof, and a second semiconductor type surface layer formed in a portion of the surface region. A multi-layer anti-reflective coating (ARC) is on the second semiconductor type surface layer, wherein the multi-layer ARC comprises at least two different dielectric layers. A layer resistant to oxide etch is above a peripheral portion the multi-layer ARC. Further layers are above the layer resistant to oxide etch, and thereby above the peripheral portion the multi-layer ARC. A window extends down to the multi-layer ARC. A photodiode region is formed by a pn-junction of the first semiconductor type surface region and the second semiconductor type surface layer.

Abstract: Methods and systems for allowing multiple devices to share the same serial lines (e.g., SDIO, SEN and SCLK) are provided. Such devices can be located, e.g., on an optical pick-up unit. Each device includes a serial interface, a device enable number (DEN) that differs from the DEN of each other device, and a plurality of registers, with at least one register being designated a device select register (DSR). The DSRs of the plurality of devices share a common address. The plurality of serial interfaces are collectively enabled and collectively disabled (e.g., via the SEN line). However, only one of the plurality of serial interfaces can be selected at one time, with the remaining of the plurality of serial interfaces being deselected. The serial interface of a device is selected when the DEN of the device is the same as the content of the DSR of the device, and deselected when the DEN of the device is not the same as the content of the DSR of the device.

Abstract: A multi-level signal uses the third/fourth signal level to signal both a word clock edge and a data word boundary. At the receiver, a level detector detects a transition to or from the third/fourth level as a clock signal transition and the word boundary. The bit clock can be recovered using a conventional clock multiplier. Bi-level signaling is used for data between the word boundaries. Additional signal states are available in the multi-level signal by modulating the pulse width at the third/fourth signal level.
