20090326729	ENERGY ARBITRAGE BY LOAD SHIFTING - Methods and systems are provided for realizing energy cost savings through load shifting utilizing a battery bank that may serve as a battery back-up on a premises for providing power in the event of a grid power outage or curtailment. A budget of unreserved cycles of battery charging and discharging is determined, taking into account the rated battery life in terms of both time (e.g., years) and number of cycles. That cycle budget is allocated to days of the year identified as days on which the greatest savings can be realized through load shifting. These days are identified by taking into account the peak and off-peak usage rates applicable on those days, any rate tiers that may be entered as a result of the additional energy expended to load shift, and the round trip efficiency of the charge/discharge cycles. Load shifting is executed in accordance with an established schedule of the identified days, by discharging the batteries during peak usage hours and charging the batteries during off-peak periods. In the event the budget of unreserved cycles exceeds the number of profitable days for load shifting, the depth of discharge on each cycle may be increased to realize greater savings on the scheduled days, at the tolerable cost of losing cycles not expected to be used in any event.	12-31-2009

20100129031	Optical Ferrule Assemblies and Methods of Making the Same - Disclosed are multifiber ferrule assemblies and methods for manufacturing the same. In one embodiment, a finished multifiber ferrule can be provided with a front end having a first front surface that extends beyond a second front surface, thereby inhibiting interaction with a laser beam during processing. A plurality of optical fibers can be fixed within respective optical fiber bores and extend from respective optical fiber bore openings to a position beyond the first front surface. The plurality of optical fibers can be processed by cutting and polishing with a laser beam for providing each optical fiber with a final polished end surface located beyond the first front surface. In further embodiments, an offset structure is positioned with respect to a finished multifiber ferrule after cutting and polishing the optical fibers.	05-27-2010
20100303416	Laser-Shaped Optical Fibers Along with Optical Assemblies and Methods Therefor - Disclosed are optical assemblies such as field-installable connectors having a laser-shaped optical fiber along with methods for laser-shaping the optical fiber. The field-installable connector includes a ferrule having front and rear opposed faces and at least one fiber bore defined longitudinally therethrough, a stub optical fiber having a distal end with a laser-shaped end face is disposed within the at least one fiber bore of the ferrule and extends a predetermined distance beyond the rear face of the ferrule, and an alignment feature operable for aligning the stub optical fiber with the field optical fiber. One method of laser-shaping the optical fiber includes rotating the optical fiber and sweeping a beam of a laser across the optical fiber and then essentially stopping the rotation of the optical fiber and sweeping the beam through the optical fiber to cut the same with a tapered and angled end face. Other methods may include shifting the laser relative to the optical fiber to create a “pencil-tip” end on the optical fiber.	12-02-2010

20080304540	SYSTEM AND METHOD FOR THERMAL ANALYSIS USING VARIABLE THERMAL RESISTANCE - A thermal measurement apparatus and method for performing heat flux differential scanning calorimetry (DSC) is disclosed. A variable thermal resistor is used to couple a measurement assembly to a heat sink in the thermal measurement apparatus, such that samples can be rapidly heated and rapidly cooled. The apparatus can be configured with a highly conductive sample assembly enclosure. The enclosure can include a high emissivity coating. In one embodiment, the enclosure extends along a longitudinal direction that is about the same as that of an infrared lamp assembly used to heat the enclosure, thereby increasing the efficiency of heating the sample enclosure. In one configuration, the variable thermal resistor comprises a gap whose gas composition can be varied during a sample measurement to independently optimize sample heating and cooling rates.	12-11-2008

The DSC can be configured with a highly conductive sample assembly enclosure. The enclosure can include a high emissivity coating. In one embodiment, the enclosure extends along a longitudinal direction that is about the same as that of an infrared lamp assembly used to heat the enclosure, thereby increasing the efficiency of heating the sample enclosure. In one embodiment, a gas-filled thermal resistor is used to couple the measurement assembly to a heat sink, such that samples can be rapidly heated and rapidly cooled.	12-11-2008
20100154439	COOLING SYSTEM USING POSITIVE DISPLACEMENT CRYOGENIC LIQUID PUMP - A cooling system employs a single-acting positive displacement bellows pump to transfer a cryogenic liquid such as liquid nitrogen from a storage dewar to a heat exchanger coupled to a measurement chamber of an instrument, wherein cooling takes place by vaporizing the liquid. Preferably, the capacity of the pump is greater than the maximum cooling requirement of the instrument, wherein both vapor resulting from vaporizing of the cryogenic liquid circulated through the heat exchanger and liquid that does not vaporize when circulated through the heat exchanger are returned to the storage dewar, wherein the vapor is subsequently vented from the dewar. Preferably, with the aid of a weir in a return line, the level of liquid in the heat exchanger is maintained full and constant, and the cooling demands are automatically met without the need for other control of the flow rate or level of the liquid. Also, unlike conventional systems, liquid transfer from the dewar does not require dewar pressurization, so that the dewar may be refilled whenever necessary without interrupting the experiment in progress.	06-24-2010
