Abstract:
A method for making all complementary BiCDMOS devices on a SOI substrate (10). Isolated n.sup.- and p.sup.- regions (20,32,34,36,40,42) are formed on the silicon layer (16) and oxidized. LOCOS oxide regions (28) are formed on selected pairs of the n.sup.- and p.sup.- regions on which gates (44) for complementary DMOS device (114,116) and field plates (46) for complementary bipolar devices (118,120) are formed. Gates (48) for complementary MOS devices (122,124) are formed directly on the oxidized silicon layer (24). N-type and p-type dopants are then implanted into the silicon layer (16) forming n body and p body areas (54,56,58,60). Selected n.sup.+ and p.sup.+ areas (66,68) are formed in the n body and p body areas (54,56,58,60) as well as selected areas of n.sup.- and p.sup.- regions (30,32,34,36,40,42). The substrate (10) is then covered with an oxide layer and windows etched therethrough to expose said n.sup.+ and p.sup.+ areas (66,68) and selected areas of the gates (44,48) and field plates (46). Metal electrical contacts (78-112) are deposited through the windows to the n.sup.+ and p.sup.+ areas ( 66,68) and the gates (44,48) and field plates (46).
Abstract:
A system and methods are provided for removal of undesired portions of a fruit or vegetable, such as removal of calyxes from strawberries before they are flash frozen. An automated process for high-throughput fruit or vegetable calyx removal includes a loading system, an identification system, and a removal system. The loading system is configured to transport the fruit or vegetable through the automated process. The loading system may also orient the fruits or vegetables along an axis of the fruit and or align the fruit or vegetables in a desired pattern, orientation, and/or arrangement. The identification system is configured to locate the calyx and determines calyx position data and an optimal cutting path for individual fruit. The removal system uses data received from the identification system to separate the calyx from the fruit or vegetable.

The extended drain MOS transistor includes a gate having field plates over the field gap drift regions. The extended drain MOS transistor may be formed in a symmetric nested configuration. A process for forming an integrated circuit containing an extended drain MOS transistor provides parallel alternating active gap drift regions and field gap drift regions with a gate having field plates over the field gap drift regions.

An electronic device has a plurality of trenches formed in a semiconductor layer. A vertical drift region is located between and adjacent the trenches. An electrode is located within each trench, the electrode having a gate electrode section and a field plate section. A graded field plate dielectric having increased thickness at greater depth is located between the field plate section and the vertical drift region.
Abstract:
A wide image scanner which can scan the image of a large scale original using only a regular image sensor is provided. The invention includes a sliding shaft, an image reading device, a number of paper width sensors, a paper edge sensor, and a control module. Whenever the paper edge sensor detects the presence of an end edge of the original, it will send a vertical control signal to the control module to control the rotation direction of the rollers. On the other hand, the paper width sensors detect the width of the original and send the horizontal control signals to the control module. From the horizontal control signals, the control module can determine the number of horizontal displacement positions and control the horizontal displacement each time for the image reading device after the paper edge sensor detects the end edge of the original. The procedure continues until the image reading device has been moved to the final displacement position predetermined by the horizontal control signal. Consequently, the entire image of the origin can automatically be read portion by portion without manual operation.
Abstract:
A wireless local area network (WLAN) transceiving integrated circuit includes a WLAN interface, an input buffer, an input buffer controller, and a processor. The WLAN transceiving integrated circuit may also include an output buffer, an output buffer controller, a transcoder, and/or an audio Coder-Decoder (CODEC). The WLAN transceiving integrated circuit is installed in a WLAN device that services voice communications. The input buffer receives packetized audio data from the WLAN interface. When the input buffer satisfies a buffer vacancy threshold, the processor and the input buffer controller cooperatively operate to fill at least a portion of the input buffer with packetized audio data. The processor copies packetized audio data from the input buffer and fills the input buffer with the copied packetized audio data to maintain an audio pattern in the input buffer. The input buffer controller fills the input buffer when the processor is available and after copying/filling is no longer effective. The processor operates to maintain the audio pattern when additional packetized audio data is received by the WLAN interface. These operations are also performed for the output buffer, which receives packetized audio data from the transcoder and writes the packetized audio data to the WLAN interface.
