Title: Optical recording medium
Inventor: KASAMI YUTAKA
IPC: G11B7/257
Filed: 2000-02-16
Granted: 2009-10-20
Abstract: A phase change optical recording medium which enables optimum direct overwrite even under high speed high density conditions without degrading repetition durability or storage stability of recorded signals. To this end, the phase change optical recording medium has a recording layer formed at least of a phase change material and is recorded and/or reproduced with a laser light beam having a wavelength ranging between 380 nm and 420 nm. A ratio Ac/Aa, where Ac is the absorption rate of said recording layer in a crystalline state and Aa is the absorption rate of said recording layer in an amorphous state, is not less than 0.9, and a crystallization promoting layer promoting the crystallization of the phase change material is contacted with at least one surface of the recording layer. By exploiting the absorption rate control and the crystallization promotion in combination, it is possible to positively compensate the difference between the physical properties of the crystal phase and those of the amorphous phase to realize optimum direct overwrite.

Abstract: Methods and apparatus for use in aligning frames in a receiver of a data transmission system include checking one or more bit positions associated with a received data stream to determine a number of bits in the bit positions, respectively, that match a predetermined bit pattern. The number for a bit position is compared to a first threshold value and a second threshold value. A bit position is identified as being associated with a false framing pattern or mimic when the number is not less than the first threshold value. A  bit position is identified as a potential framing bit position or possible framing bit position when the number is not less than the second threshold value. The first threshold value is changed when a bit position is identified as a potential framing bit position and another bit position is identified as being associated with a false framing pattern. For example, the first threshold value may be increased by a given value for every frame that a bit position is identified as a potential framing bit position and another bit position is identified as being associated with a false framing pattern. The given value may be a value of one, a value less than one, or a value greater than one. Frame alignment is declared when a bit position is identified as a potential framing bit position and no other bit position is identified as being associated with a false framing pattern.

Title: Method and system for supporting multiple operating systems on the same disk running on different computers at the same time
Inventor: CRONK MATTHEW SLADE
IPC: G06F9/445
Filed: 2001-01-23
Granted: 2006-08-01
Abstract: A method and system for running, on different computers at the same time, multiple operating systems from the same shared system resource is provided. This is accomplished, for example, by using persistent elemental disk reservations. Each machine reads the master boot record without reservation to determine the partition of the operating system to be booted. Each machine then makes an elemental exclusive write persistent reservation for accessing the operating system boot partition. This is followed by each machine making another elemental exclusive write persistent reservation for accessing the operating system partition itself. Each machine is assigned a different operating system partition even if they are running the same operating system. The unique reservation key for these reservations is created from at least on of a Processor ID, a Cluster ID, a Multiple Processor partition ID, a Non-Uniform Memory Access complex ID, and/or a Non-Uniform Memory Access node ID.

Xanthophyll ester concentrates having a total xanthophyll ester content of at least 40 wt.% and preferably greater than about 55 wt.% are al so obtained, A method of obtaining a trans-xanthophyll ester concentrate of high purity includes contacting plant material containing xanthophyll esters with a hydrocarbon solvent for a time sufficient to extract xanthophyll esters from the plant material, separating the hydrocarbon solvent and extract dissolved therein from the remaining plant material, evaporating the hydrocarbon solvent from the dissolved extra ct to obtain a crude xanthophyll ester concentrate, admixing the crude xanthophyll ester concentrate with an alcohol at approximately ambient temperature to dissolve non-xanthophyll impurities and cis-xanthophyll esters from the concentrate and removing the alcohol containing impurities and cis-xanthophyll esters from the crude traps-xanthophyll concentrate to obtain a purified trans-xanthophyll ester concentrate. By using only the corollas of marigold flowers, lutein ester concentrates of high purity are obtained with pesticide residue s absent from the concentrate at parts per billion detection levels.

Title: Synchronous circuit synthesis using an asynchronous specification
Inventor: HOE JAMES C
IPC: H04L1/00
Filed: 2000-08-18
Granted: 2008-06-17
Abstract: A method for specifying and synthesizing a synchronous digital circuit by first accepting a specification of an asynchronous system in which stored values are updated according to a set of state transition rules. For instance, the state transition rules are specified as a Term Rewriting System (TRS) in which each rule specifies a number of allowable state transitions, and includes a logical precondition on the stored values and a functional specification of the stored values after a state transition in terms of the stored values prior to the state transition. The specification of the asynchronous circuit is converted into a specification of a synchronous circuit in which a number of state transitions can occur during each clock period. The method includes identifying sets of state transitions, for example by identifying sets of TRS rules, that can occur during a single clocking period and forming the specification of the synchronous circuit to allow any of the state transitions in a single set to occur during any particular clocking period.

Abstract: An uninterruptible power supply system (44) has standby and backup modes and can change to backup mode upon detection of a grid fault. In both modes an alternator (14) rotates at synchronous speed so that backup mode capability is ready. An energy storage unit (54) remains coupled to the grid (38) in standby mode so that it is charged, ready to supply power when changed to backup mode. In standby mode, first and third clutches (48, 52) are disengaged and engaged, transmitting alternator rotary motion to a flywheel (46) but not therefrom to a heat engine (12). In backup mode, first and third clutch (48, 52) are engaged and disengaged to permit the alternator (14), via a second clutch (50), to overrun the flywheel (46) and allow transmitting of flywheel torque to accelerate the heat engine (12) to starting speed for driving the alternator (14) to supply power to the grid (38) after the engine (12) is at operating speed and coupled to the alternator (14) through the locked second clutch (50) and engaged with the third clutch (52).

Abstract: Solid state thermionic energy converter semiconductor diode implementation and method for conversion of thermal energy to electric energy, and electric energy to refrigeration. In embodiments of this invention a highly doped N region (16) can serve as an emitter region, from which carriers can be injected into a gap region. The gap region can be P-type, intrinsic, or moderately doped N-type (14). A hot ohmic contact (20) is connected to the N-type region. A cold ohmic contact (12) serves as a collector and is connected to the other side of the gap region. The cold ohmic contact has a recombination region formed between the cold ohmic contact and the gap region and a blocking compensation layer that reduces the thermoelectric back flow component. The heated emitter relative to the collector generates an EMF which drives current through a series load. The inventive principle works for hole conductivity, as well as for electrons.
