摘要:
Methods, compositions, and devices for alleviating the problems of toxic discharge of aldehydes present in waste streams are disclosed. The methods relate to reducing neutralized aldehydes wherein the neutalized aldehydes are formed by treating aldehydes with amino acids and thereinafter are reduced. These reduced, neutralized aldehydes do not revert back to toxic aldehydes, but form amino acids and thus allow waste containing aldehyde to be more environmentally safely disposed.

Fabricating electrical isolation properties into a MEMS device is described. One embodiment comprises a main substrate layer of a high-resistivity semiconductor material, such as high-resistivity silicon. The high-resistivity substrate is then controllably doped to provide a region of high-conductivity in the main substrate. Electrical isolation is achieved in such an embodiment by patterning the high-conductivity region either by masking the main substrate during the doping or etching through the doped, high-conductivity region in order to form regions of high conductivity. Effective isolation results from confinement of electrical currents to the lowest-resistance path. An alternative embodiment employs the fabrication of pn junctions and the use of reverse biasing to enhance the electrical isolation. A further embodiment comprises a main substrate layer of low-resistivity semiconductor material with a layer of insulator deposited thereon. High-conductivity or low-resistivity material is then grown on top of the insulator to create electrically isolated conductors.

A virtual assistant system (VAS) (102) supports call services (104), message services (106) and profile services (108) and interfaces to both a telephone network (114) and to a data network (116). The telephone network (114) may be the PSTN and/or another telephone network. The data network (116) may be the Internet, an Intranet or another data network in which communications are packet based. The call services (104) include call receipt services, call initiation services, conference calling services and other types of services in which calls are initiated, routed and/or completed and that are typically provided by a telephone company. The message services (106) include voice mail, email, Faxes, video mail, and other types of messages that include one or more types of media, e.g., audio or visual. The profile services (108) uniquely identify each subscriber and provide contact information for the subscriber. [All communications (email, voice mail, Fax, etc.) for the subscriber are received via a single telephone number. For example, the subscriber has account 8001234567 for calls, voice mail, Fax, IP calls, etc. and 80012345678@VAS.com for email. Based upon the content of the reach lists and corresponding schedules, the VAS (102) routes communications and messages to the subscriber and also notifies the subscriber of incoming communications. The single number, IP address (network address) and/or email address may also be used to access all messages for the subscriber.]

The disclosure relates to a system for protecting HgCdTe and the like MIS arrays from breakdown during fabrication due to electrostatic charge buildup on the array capacitors. This is accomplished by building into the structure a short circuit across the capacitor plates with a fuse region therein that will evaporate when a voltage is placed thereacross which is sufficient to cause evaporation and low enough not to damage the capacitors.

The present invention is embodied in a method of operating a charge-coupled device (CCD) having a non-destructive readout floating gate amplifier to minimize noise on the floating gate. A pair of control gates are adjacent to and partially overlap the floating gate and are electrically insulated therefrom. Noise caused by presetting the floating gate voltage is minimized by presetting after a series of "reads" instead of after each "read". Coherent clock noise induced by capacitive coupling of the control gates to the floating gate is eliminated by applying appropriate simultaneous signals to the control gates. Device sensitivity is improved.
