Systems and methods for forming an encapsulated MEMS device include a hermetic seal which seals an insulating gas between two substrates, one of which supports the MEMS device. The hermetic seal may be formed by heating at least two metal layers, in order to melt at least one of the metal layers. The first melted metal material flows into and forms an alloy with a second metal material, forming a hermetic seal which encapsulates the MEMS device.

Systems and methods for software licensing enforcement using an ACPI BIOS. A digital license is provided that includes information about both the software and hardware on which it is to be run. The licensing process receives hardware and software information from the end user and binds the license to both. A main BIOS binary contains code and static motherboard specific data. Dynamic state values containing, e.g., machine-specific system management data, such as, a serial number may be stored subsequently on NVRAM or its equivalent. The main BIOS binary allows provides sufficient functionality to test the hardware. Once the software to be loaded on the system is known, a corresponding digital license containing both the software and hardware information is loaded to NVRAM.

A method and apparatus are provided for maintaining a temperature between a first value and a second value. The method and apparatus utilize a heat transfer device capable of cycling through a series of cycles, the device being capable of changing the temperature from the second value to the first value when operational. During each cycle the device transfers heat for a first period of time when the temperature reaches the second volume until the first value is reached and thereafter the device stops transferring heat. The first period of time is compared to a desired cycle-on period of time during each cycle and the second temperature value then is adjusted for a subsequent cycle of the device so the first period of time when the device transfers heat approaches the desired cycle-on period of time. There may also be provided temperature controls for a liquid heater having a jacket containing the liquid. The jacket has an inner heated wall and an outer wall spaced apart from the inner wall. The controls include a temperature sensor capable of fitting to the jacket so that the sensor contacts the inner wall and the liquid. A control module monitors temperature sensed by the temperature sensor. The control module causes the heater to stop heating when the temperature is heated by the heater to a first value and causes the heater to heat when the liquid cools to a second value lower than the first value. The control module senses overheating when temperature sensed by the sensor increases to a third value, higher than the first value, when the heater is not heating, and then causes the heater to shut down.

A torque measuring device has a torsion bar with effective length adjustable to show different energy absorption capability. One end of the torsion bar's effective length is held stationary while a torque from a torque controlled winding tool is applied to the other end through a one direction of rotation clutch. The actual torque applied to the torsion bar is measured after which the torque on the bar is released.

In order to check the strength and seal of a fitting that has been swaged on a tubular part, the difference between the nominal inside diameter of the tube and the larger diameter of an inside circumferential groove formed in such tube by swaging of the tube wall radially outwardly into a mating groove of the fitting is measured by a handheld gauge apparatus that includes a probe adapted to be inserted into an open end of the tube adjacent the fitting to perform successive, comparison measurements of the tube's interior wall surface, first at a location axially spaced from the swaged groove, and secondly at the groove. The probe includes a cylindrically shaped probe head of a diameter less than that of the tube's nominal inside diameter so that the probe head can be inserted and cocked at a slight angle relative to the tube axis, and a pivoted arm having a feeler tip disposed in a slotted opening in the probe head and so mounted as to be movable transversely relative to the circumference of the probe head. The feeler tip is displaced to contact the interior wall surface of the tube, initially at a location axially spaced from the groove in order to zero the gauge, and thereafter at the location of the groove to measure its relative depth, while the probe is held so that at both measurement locations the probe head is maintained at the same cocked angle relative to the tube axis.

A method of burning a fuel with high efficiency comprises providing a combustion chamber having a combustion region, providing a natural fuel within the combustion chamber on one side of the combustion region, providing a filtered fuel, and providing a substantially cylindrical injector on an opposing side of the combustion region, the injector comprising: an exhaust port in an axial center of the injector; a notch surrounding a circumference of the injector; and a plurality of intake ports in a periphery of the injector and configured to port fluid from the notch to the combustion region. The flow of the fluid toward the center of the combustion region, while the natural fuel is burning within the combustion chamber, causes at least one vortex in which the combustible substances further burn with the air and the filtered fuel.

A system and method for indexing and searching a free format data source is provided. Indexing the free format data source includes normalizing data from the free format data source and creating a master index based on the normalized data. The master index may be updated through synchronization with the free format data source when a change in the data occurs. A search query may be executed against the master index and/or one or more child indexes to search for records. The search query may be normalized and transformed before being executed. The master index may be replicated into the one or more child indexes for scaling and load balancing purposes. Searches may be performed by search agents in parallel at the master index and/or the child indexes.
摘要:
A heater for a liquid has a combustion chamber, a jacket for the liquid extending about the combustion chamber and a burner head assembly connected to the combustion chamber. The burner head assembly includes a housing having a burner mounted thereon and a hollow interior. A control module and a fan are mounted in the hollow interior, the fan being connected to an electric motor. A compressor and a fuel pump are mounted on the housing and are operatively connected to the electric motor. The control module may include controls for exercising components of the heater prior to combustion, thereby verifying operation of these components. Preferably there is a speed control for the motor, such as a closed loop speed control which regulates motor speed and accordingly output of the heater. Preferably there is a backup system using a lookup table in the event that the closed loop speed control fails. Also preferably there is provision for monitoring flame sensor functionality by providing an indicator light which mirrors operation of the flame sensor. The heater may have a selective soft start for the coolant pump which operates only when required so as to reduce unnecessary chatter on the motor relay. A system is also provided for distinguishing true overcurrent faults from overcurrents arising from voltage changes during starting of the vehicle engine. Reignition algorithms are provided to restart the burner in the event of flame sputters caused, for example, by fuel bubbles, but shut off the heater in the event that the fuel is truly cut off.
