The present invention relates to a novel method for analyzing nucleic acid sequences based on real-time detection of DNA polymerase-catalyzed incorporation of each of the four nucleotide bases, supplied individually and serially in a microfluidic system, to a reaction cell containing a template system comprising a DNA fragment of unknown sequence and an oligonucleotide primer. Incorporation of a nucleotide base into the template system can be detected by any of a variety of methods including but not limited to fluorescence and chemiluminescence detection. Alternatively, microcalorimetic detection of the heat generated by the incorporation of a nucleotide into the extending template system using thermopile, thermistor and refractive index measurements can be used to detect extension reactions.

Methods and apparatuses to manage working states of a data processing system. At least one embodiment of the present invention includes a data processing system with one or more sensors (e.g., physical sensors such as tachometer and thermistors, and logical sensors such as CPU load) for fine grain control of one or more components (e.g., processor, fan, hard drive, optical drive) of the system for working conditions that balance various goals (e.g., user preferences, performance, power consumption, thermal constraints, acoustic noise). In one example, the clock frequency and core voltage for a processor are actively managed to balance performance and power consumption (heat generation) without a significant latency. In one example, the speed of a cooling fan is actively managed to balance cooling effort and noise (and/or power consumption).

A method and system for positioning a detachment zone and an implant, such as a vaso-occlusive coil or a stent, attached thereto in a body. A catheter is inserted within a vascular cavity in the body. The implant is attached to a distal end of a delivery member using a temporary connection, such as an electrolytic, mechanical, hydraulic, heat-sensitive or Radio Frequency (RF) sensitive connection, with an insulation member between the wire and the implant. The delivery member, temporary connection and implant are advanced through the catheter. An electrical condition, such as current, voltage and impedance, related to the position of the temporary connection in the catheter is monitored with an electrical measurement device or sensor. The electrical condition changes when the temporary connection reaches or exits a predetermined location, for example, the distal end of the catheter and contacts a conductive component of the body, such as blood in an aneurysm.

A light valve such as an active matrix LCD between crossed polarizers, utilizing, for instance, individual transistors to control each "pixel area" of the LCD and storage elements to store video signal data for each pixel, with optically shielded "dead spaces" between pixels to eliminate electric field cross-talk and non-information-bearing light bleed-through, is illuminated with a bright independent light source which creates a video image projected via specialized projection optics onto an internal or external screen without distortions, regardless of the angle of projection onto the screen. Use of heat sinks, IR reflective coatings, heat absorbing optics, optional fluid and a thermistor controlled pixel transistor bias voltage injection servo circuit stabilizes image performance, maintaining accurate color and contrast levels as the LCD changes temperature. In one embodiment of the invention, use of a multi-color LCD with a stepped cavity, producing different thicknesses of LCD for the different wavelengths that pass through it, allows a linear correspondence between the wavelengths passing through the LCD to produce true black, high contrast and CRT-like color rendition. A dichroic mirror arrangement is used to overlap differently colored pixels in the projected image. Use of striped mirrors duplicate pixels, where necessary, eliminating spaces between pixels, creating a continuous image with no apparent stripes or dots. A special venetian-blind type of screen is also disclosed and methods for using the system to view three-dimensional video are also explained.

A printer that applies donor material from donor patches on a donor web to a receiver medium using a thermal printhead that generates heat and a method for operating such a printer are provided. The method comprises the steps of: receiving a print order requesting the printing of a quantity of images; determining a temperature of the printhead; printing a designated number of the quantity of the images in a sequence; determining a length of time of a programmed delay; delaying the printing for the determined length of time of the programmed delay; and printing remaining images from the quantity of images. The length of each programmed delay is determined by using the temperature of the printhead and a time rate of cooling of the printhead and, is determined in a manner that provides a sufficient cooling time to prevent the printhead from reaching a maximum printhead temperature during printing.

The detector for monitoring decrease in air flow rate due to air filter clogging. It is based on combination of three essential components: the air flow sensor, a threshold detector and an indicator. The air flow sensor is built in form of a novel thermo-anemometer which contains a thermistor, a heating element, and a thermal insulator. Temperature of the sensor is maintained above the air temperature by a constant value by means of an electronic servo circuit. The threshold detector is implemented either in a hardware or software. A novel design of a thermo-anemometer (closely related to a hot wire anemometer) automatically compensates for variations in the air temperatures. The thermo-anemometer triggers the threshold circuit when air flow rate drops below a preset level. For reduction of power consumption, the detector may employ two additional sensors: one is for detection of the blower operation and the other is a presence detector to enable the alarm in presence of people to perceive the alarm. The device automatically calibrates itself upon installation of a new or cleaned air filter. The applications include residential and commercial air conditioners, air heaters, internal combustion engines, vacuum cleaners and other systems where air filters are employed.
