摘要:
A method of calibrating a metabolic analyzer incorporating an oxygen analyzer and a NDIR carbon dioxide analyzer in the field that does not require the use of gas cylinders containing gases of known concentration is described. In calibrating the CO2 detector, at the time of factory setup, the detector output for a gas of a known concentration is measured and stored in the memory of the metabolic analyzer's microprocessor, as is the detector output voltage when the IR source is dimmed by a known percentage. Subsequently, in the field, CO2 levels in ambient air and cell pressure are measured at two different flow rates through the sample chamber and the IR source is again dimmed by the same percentage as had been used at the time of factory setup. Based upon the resulting readings, both the zeroing and span adjustment factors can be computed.

A method of delivering a radiation therapy treatment plan to a treatment area of a patient. The treatment plan is delivered using a radiation therapy system including a moveable support for supporting a patient, and a gantry moveable relative to the support. The gantry supports a radiation source, a set of jaws having a jaw width and a multi-leaf collimator for modulating the radiation during delivery of the treatment plan. The support is moved during delivery of the treatment plan to the treatment area, and the width of the jaws is dynamically adjusted during delivery of the treatment plan to the treatment area.

A environment of server and client systems for revenue generation, where a component is provided for broadcasters to broadcast and/or transmit programming, and where advertisers can create advertisement, and bid for advertising time on the transmitted programming. Advertisers are empowered by the network's ability to perform targeted advertising and/or product placement base on viewer attribute, programming content, and other criteria collected by the environment. Broadcasters are empowered by the network's ability to produce relatively high conversion rate using an viewer interface allowing enabling viewers to perform click-to-buy, click-to-send-lead, and/or click-to-send information, without much disruption to viewing of the transmitted programming. Also disclosed is a business method of generating revenue by utilizing an environment of server and client systems for targeted advertising and/or product placement, where incentives are created by and for broadcasters, advertisers, content providers, creator of the environment, and viewers.

A non-linear element is formed on a flexible substrate by securing the substrate to a rigid carrier, forming the non-linear element, and then separating the flexible substrate from the carrier. The process allows flexible substrates to be processed in a conventional fab intended to process rigid substrates. In a second method, a transistor is formed on a insulating substrate by forming gate electrodes, depositing a dielectric layer, a semiconductor layer and a conductive layer, patterning the conductive layer to form source, drain and pixel electrodes, covering the channel region of the resultant transistor with an etch-resistant material and etching using the etch-resistant material and the conductive layer as a mask, the etching extending substantially through the semiconductor layer between adjacent transistors. The invention also provides a process for forming a diode on a substrate by depositing on the substrate a first conductive layer, and a second patterned conductive layer and a patterned dielectric layer over parts of the first conductive layer, and etching the first conductive layer using the second conductive layer and dielectric layer as an etch mask. Finally, the invention provides a process for driving an impulse-sensitive electro-optic display.

A concentrated solar energy device is connectable to a solar array and includes a photovoltaic cell that provides electrical energy and heat from a solar energy source, a thermally conductive element, concentrating optics, and a housing. The concentrating optics are positioned between the solar energy source and the photovoltaic cell and are aligned with the solar energy source. The thermally conductive element functions to dissipate heat from the photovoltaic cell. The housing and the concentrating optics are attached to one another and together enclose the photovoltaic cell and a portion of the thermally conductive element. An optical film may be positioned over the concentrating optics during assembly, installation, and/or maintenance of the concentrated solar energy device.

A thermally managed solar cell system includes a photovoltaic cell for generating electricity and heat. The system includes a housing, a base, and a heat removal device. The housing surrounds the solar cell system and has an open, rear portion. The base is positionable in the open portion of the housing and supports the photovoltaic cell. The base is also thermally conductive and spreads heat generated from the photovoltaic cell. The heat removal device and the base act as a single unit with the heat removal device being coupled to the base to remove the heat from the base.
