Abstract:
This invention discloses the method of forming silicon nitride, silicon oxynitride, silicon oxide, carbon-doped silicon nitride, carbon-doped silicon oxide and carbon-doped oxynitride films at low deposition temperatures. The silicon containing precursors used for the deposition are monochlorosilane (MCS) and monochloroalkylsilanes. The method is preferably carried out by using plasma enhanced atomic layer deposition, plasma enhanced chemical vapor deposition, and plasma enhanced cyclic chemical vapor deposition.
Abstract:
A wavelength selective switch (WSS) with hitless switching. The WSS includes the fiber collimator array, the focusing lens, collimating lens, diffraction grating, focusing lens, and attenuation reflection unit array. Each attenuation reflection unit has an interconnected transmission-type MEMS attenuator and a one-dimension MEMS reflector. The transmission-type MEMS attenuator is positioned in the front of the one-dimension MEMS reflector. The central axis of the transmission-type MEMS attenuator aligns and coincides with that of the one-dimension MEMS reflector, with the two central axes being glued together. The WSS of the present invention effectively utilizes the combination of a one-dimension reflector array and a transmission-type optical attenuator chip. With the use of one-dimension reflector array, instead of the known two-dimension reflector array, the complexity of design and manufacture is greatly reduced, thereby reducing the production costs of the switch.
Abstract:
The present invention is a process of making a germanium-antimony-tellurium alloy film using a process selected from the group consisting of atomic layer deposition and chemical vapor deposition, wherein a silyltellurium precursor is used as a source of tellurium for the alloy film and is reacted with an alcohol during the deposition process.
Abstract:
Described is a summarizing a web entity (e.g., a person, place, product or so forth) based upon the entity's appearance in web documents (e.g., on the order of hundreds of millions or billions of webpages). Webpages are separated into blocks, which are then processed according to various features to filter the number of blocks to further process, and rank the most relevant blocks with respect to the entity that remain. A redundancy removal mechanism removes redundant blocks, leaving a set of remaining blocks that are used to provide a summary of information that is relevant to the entity.
Abstract:
A silicon nitride dielectric film for use in an MR head according to the present invention comprises from about 38% to 44% by volume of Si, from about 35% to 37% by volume of N, and from about 21% to 24% by volume of H. The dielectric film is formed by plasma enhanced chemical vapor deposition (PECVD) at relatively low temperatures. A plurality of gases capable of reacting to form silicon nitride are introduced into a PECVD reactor. An electric field is generated in the reactor to produce a plasma. The gases in the reactor react in the presence of the electrical field to form a silicon nitride dielectric film.
Abstract:
A controller is provided for HVAC equipment. The controller receives a set of internal temperature values, and a set of external temperature values, the set of external temperature values representing at least one non-current temperature. The controller determines a predictive internal temperature value from the set of internal temperature values and a predictive external temperature value from the set of external temperature values. The controller receives an internal humidity value representing humidity within the premise, the controller further controls the HVAC equipment to modify the humidity within the premise when the received internal humidity value is different from a humidity set point; and the humidity set point is regulated by a humidity limit value, the humidity limit value being where condensation forms, the humidity limit value being calculated using the predictive internal temperature value and the predictive external temperature value.

Abstract:
This invention discloses the synthesis of metal chalcogenides using chemical vapor deposition (CVD) process, atomic layer deposition (ALD) process, or wet solution process. Ligand exchange reactions of organosilyltellurium or organosilylselenium with a series of metal compounds having neucleophilic substituents generate metal chalcogenides. This chemistry is used to deposit germanium-antimony-tellurium (GeSbTe) and germanium-antimony-selenium (GeSbSe) films or other tellurium and selenium based metal compounds for phase change memory and photovoltaic devices.

Abstract:
The objective of this invention is to make solar water heating affordable and compatible with conventional gas or electric water heaters. Solar energy is clean and renewable. However, solar water heating has not been in wide use in the US mainly due to two reasons: first, the cost of a current solar water heater is generally too expensive for an average household; second, a typical solar water heater uses ethylene glycerol as a heat transfer fluid to prevent freezing and needs additional space for an extra exchange tank. Our design includes evacuated tube collector panels for efficient collection of solar energy, utilizes two unique three-way adaptors to connect solar collector panels to a conventional water heater for storing solar hot water, and is operational even in freezing temperature. These improvements eliminate the need for an extra exchange tank and significantly reduce the cost of a solar water heater.
