A remote download of microprocessor code for an irrigation controller is provided. A microprocessor, on an irrigation controller, is executing program code (in volatile memory) and receives a remote download of updated program code, which it stores into non-volatile random access memory, e.g., flash memory. The microprocessor is configured to receive the updated program code, via a communication port, and to store the updated program code into the non-volatile flash memory. Optionally, the updated program code is received at multiple controllers via a global transmission on a communication bus. The microprocessor receives a communication causing it to re-start. In response to the re-start communication, the microprocessor fetches the updated program code stored in the non-volatile flash memory into the program memory RAM to replace the original program code, and begins execution of the updated program code in the program memory RAM. A device is also provided for directing the download of program code to irrigation controllers. Options provide for global download of entirely new program code, global and / or individual download of particular pages of updated program code, and global downloads to controllers grouped by communication speed.

A voltage sensor is described that consists of a plurality of identical series-connected sections, where each section is comprised of an arrangement of impedance elements. The sensor is optimized to provide an output ratio that is substantially immune to changes in voltage, temperature variations or aging. The voltage sensor can be scaled to various voltage levels by varying the number of series-connected sections.

A controller (301), for example on a field interface of a resource management system (300), determines a location of a mobile object (303a, 303b, 303c) and controls an environment thereof. The controller (301) receives, via a first transceiver (307), a communication including information representative of the mobile object; receives a command via a second transceiver (317) and controls the environment outside of the mobile object responsive to the command and / or the communication. A controller, for example on the mobile object (303a, 303b, 303c), detects a location of the mobile object (303a, 303b, 303c) via device (305a, 305b, 305c). The controller collects information about the mobile object including location; transmits, to a controller via its transceiver, a communication including the information; receives a command via its transceiver; and controls operation of the mobile object responsive to the command.

A method of manufacturing light guide by filling a polymer tube with a monomeric mixture then pressurising and heating the full length of the polymer tube to initiate and maintain polymerisation in the tube. An apparatus for performing the method is also described in which the polymer tube is placed in a reaction vessel and a temperature controlled fluid is circulated to regulate the temperature in the vessel.

A method of fabricating a semiconductor multilevel interconnect structure employs a dual hardmask technique in a dual damascene process. The method includes using amorphous carbon as a first hardmask layer capable of being etched by a second etch process, and a second hardmask layer capable of being etched by a first etch process, as a dual hardmask. By virtue of the selective etch chemistry employed with the dual hardmask, the method affords flexibility unattainable with conventional processes. The via is never in contact with the photoresist, thus eliminating residual photoresist at the trench / via edge and the potential “poisoning” of the intermetal dielectric layer. Since trench / via imaging is completed before further etching, any patterning misalignments can be easily reworked. Because the amorphous carbon layer and the second hardmask layer are used as the dual hardmask, the photoresist can be made thinner and thus optimized for the best imaging performance.

A communication system and method with orthogonal, block encoding is provided. Encoded signals are transmitted by repeating transmissions of symbol blocks with a phase or sign change selected for each block from a sequence of phase or sign changes. Different symbols are transmitted using orthogonal sequences. The decoding uses different orthogonal sequences for separating the received encoded signals into corresponding separate channels. The orthogonal encoding is removed from the encoded transmitted signals and corresponding ones of the repeated symbols are added in successively received repeated blocks after the orthogonal encoding is removed. A transmitter uses a digital source encoder to encode information into symbols, and each symbol is repeated a preselected number of times to successively produce groups of repeated bits. Each repeat bit is changed in phase or sing by application of a sign or phase change determined by a selected assigned orthogonal code associated with the transmitter. The sign changed bits are interleaved from a number of such groups to successively generate a number of blocks, each composed of the different sign or phase changed bits of the preselected number of repeated groups and having a collective sign or phase change corresponding to a common sign change or phase shared by all bits of the block. The interleaved blocks then modulate a radio signal for transmission.

The invention discloses a powder element fertilizer as well as a preparation method and application method thereof. The method is characterized by comprising the following steps: uniformly mixing a soluble trace element fertilizer, a citrate-soluble trace element fertilizer, an acidifier and an anticaking agent to obtain a mixture, grinding and screening the mixture until the particle size is less than 150 meshes, thereby obtaining the powder trace element fertilizer; and coating seeds or other granular fertilizers with the powder trace element fertilizer. Compared with the prior art, the technique enhances the dispersion uniformity of the minor elements in soil and the absorption and utilization efficiency of the seeds for the minor elements, implements unification of the short-term fertilizer efficiency and long-term fertilizer efficiency, and reduces the problem of caking of the powder product in the use process.

The present invention relates to a structurally rigid, X-ray translucent backboard for transporting an injured person from the scene of an injury to a treatment center. The backboard comprises a planar top side which contacts the patient and a bottom side forming a single curvilinear shape that provides structural support to the planar top side. A hollow, foam filled core formed between the planer top side and the curved bottom side helps provide sufficient X-ray translucence and structural support to the backboard.

A projector that projects video light corresponding to an image signal onto a display surface includes: a light source device that emits light; a housing that houses at least the light source device; a projection lens, that is, an optical element that transmits the video light projected onto the display surface and emits the video light toward the outside of the housing; a detecting unit that detects detection light supplied to the optical element; and a control unit that adjusts a light amount of the video light on the basis of a result of the detection by the detecting unit. The projector is set such that, when the optical element is in a normal setting state, the light amount density of the video light is equal to or lower than a predetermined value on an emission surface for emitting the video light of the optical element.
