  • Patent number: 6955712
    Abstract: A proton-conducting polymer, a preparation method thereof, a polymer membrane manufactured from the proton-conducting polymer, and a fuel cell having the polymer membrane are provided. The proton-conducting polymer contains an acid-bearable aromatic group covalently bonded to its polyimide backbone and a proton-conducting acid group attached to the aromatic group. A polymer membrane manufactured from the proton-conducting polymer has greater mechanical strength and ionic (protonic) conductivity than existing sulfonated polyimide membranes and thus improves the performance of fuel cells. In addition, the proton-conducting polymer membrane is low cost, enabling automobile fuel cells to be commercialized. Since the proton-conducting polymer membrane is less permeable to methanol, it can be used effectively for DMFCs without causing cell performance degradation.

  • Patent number: 6955047
    Abstract: Disclosed is a master cylinder wherein a seal member is given plural seal functions to reduce the number of seal members for partitioning a drain portion of the master cylinder, a constant-pressure chamber of a booster and the atmosphere from one another, so that the master cylinder is simplified in construction and reduced in manufacturing cost. When a piston is operated by an output shaft of the booster attached to a booster mounting surface of a cylinder body, the operating fluid from the fluid pressure chamber partitioned by a fluid-tight seal member is supplied to a brake system. An annular complex seal member is fit in an internal seal stepped portion which is formed by radially expanding an opening portion of the cylinder which opens to a booster mounting surface. A slide seal portion of the complex seal member partitions a drain portion behind the fluid-tight seal member from the constant-pressure chamber of the booster through sliding contact with the piston.

  • Patent number: 6956489
    Abstract: A method for monitoring the condition of an electric current-carrying heating element involving installing the heating element in a location and setting the initial composition Ci of the material as a reference baseline at an initial time Ti corresponding to said installation of the heating element. Data is then collected reflecting the subsequent composition Cs of the heating element material after a subsequent time Ts at the installed location and any change in the material composition of the heating element between Ti and Ts is monitored. An alarm is sent when the change reaches a threshold value indicating a possible failure condition. According to one embodiment, an impedance monitor is provided that calculates and compares impedance at the required levels of accuracy to determine changes in material composition. The impedance monitor, or portions thereof may be embedded within a microcontroller for increased portability and functionality.

  • Patent number: 6955407
    Abstract: A negative pressure type brake hydraulic pressure generating device is proposed in which the stroke on the operating side can be set independently of the stroke on the output side. A slide resistance imparting means is provided between the fixed shell and a piston having a built-in control valve introducing atmospheric air to cancel the slide resistance which is the cause of increased stroke hysteresis of the piston, i.e. the slide resistance applied to the piston at airtight seal portions between the power plate and the piston.

    Abstract: A method and system are described for monitoring a deliverable radio frequency (RF) power of an amplifier operable on a monolithic microwave integrated circuit (MMIC). According to an exemplary embodiment, circuitry is configured to capture, on the MMIC, a first portion of an RF signal transmitted from the amplifier to a load, and a second portion of the RF signal reflected from the load back to the amplifier. Circuitry is also configured to generate, on the MMIC, a first signal proportional to an RF power of the first portion of the RF signal, and a second signal proportional to an RF power of the second portion of the RF signal. Additional circuitry is configured to subtract a first reference signal from the first signal to produce a third signal, and a second reference signal from the second signal to produce a fourth signal. Finally, circuitry is configured to subtract the fourth signal from the third signal to produce an output signal proportional to the deliverable RF power of the amplifier to the load.

  • Patent number: 6954193
    Abstract: A method and apparatus is described for providing a consistent visual appearance of pixels of a display screen with respect to a viewing position. Variations between perceived pixel level values associated with the pixels and corresponding pixel level values may be compensated for. Variations are associated with a viewing angle between pixel location and the viewing position and compensated for by applying a respective different correction factor to each of the corresponding pixel level values based on a respective viewing angle. Accordingly different non-linear correction curves corresponding to locations may be established relating a range of pixel level values to a corresponding range of corrected pixel level values associated with the viewing position. A calibration pattern may be further be displayed and user inputs associated with locations received responsive to calibration pattern.
