Patent CA-2526761-A1 (CA)
Inventor: PARACHINI DAVIDE
IPC: F22B1/28
Filed: 2005-11-10
Abstract: According to the invention, a steam generator (40) is provided having a housing (52) for forming a steam generating chamber (54), the housing having a steam outlet port (68). A  heater plate (56) is supported by the housing (52) within the steam generating chamber. A water inlet valve (42) is fluidly connected to the housing for selectively supplying water into the steam generating chamber whereby water is directed to the heater plate for conversion to steam. The heater plate (56) forms a bottom wall of the steam generating chamber and is arranged to have a high point. The water inlet valve is opened and closed in accord with a duty cycle which alternates between two phases: a fill phase duty cycle and a steady state duty cycle. The steady state duty cycle is relatively slower than the fill phase duty cycle such that during the fill phase water the level of water in the steam generating chamber rises and in the steady state phase the level of water in the steam generating chamber decreases. In a boil dry condition (over threshold), the high point of the heater plate begins to overheat first such that a temperature sensor mounted to the heater plate at the high end of the heater plate can operate to prevent overheating of the heater plate. It is also possible to sense for leakage current to allow for safe operation of the steam generator at critical heat flux, thus ensuring a high efficiency and fast steam generation.

Abstract: Image reproduction and recording system, having exclusive plurality of uses, with the methods for positioning, processing and controlling, with flexible operations (hand, robot, vehicle) of head carrier, works based on mechanical-guiding-apparatus-free positioning system. The common apparatuses include:  head Gamier, sprayer/reader or sprayer/reader array, and computer. Additional apparatuses used in relative-motion-based method or wave-based method, include operation-module(OM) and motion-detectors(MD), or operation-unit(OU) and communication-units(CU's), respectively. The MD and OM provide the information of positioning for computer to determines the relative position and direction of the head array on head carrier. The CU's radiate and receive signal needed for determining distance information. The OU processes and converts the received signal into distance-related data and pass to computer. The computer determines the coordinates of a head in the head array from these data, and sends it back to OU or OM. Then the OU or OM sends the color data and spraying commands to head array, and provides power for head, or sends reading commands to reader array for reading color data.

Patent CA-2571478-A1 (CA)
Inventor: GILGEN ROBERT L
IPC: G06K9/36
Filed: 2005-05-20
Abstract: A method of improving run length video encoding commands (62) is described in which all compression commands that require a current pixel value to be compared to a previously sent pixel value to determine whether compression can take place in a longer run is adjusted to relieve stringent match conditions.  Instead of requiring an exact match, the compression engine subtracts one pixel value from another, and compares the absolute value of the result to a threshold value (63). In this way, run length can be lengthened for purpose of compression and compression efficiency can be increased.
