A method and system for synchronizing the output signal phase of a plurality of frequency divider circuits in a local-oscillator (LO) or clock signal path is disclosed. The LO path includes a plurality of frequency divider circuits and a LO buffer for receiving a LO signal coupled to the plurality of frequency divider circuits. The method and system comprise adding offset voltage and setting predetermined state to each of the frequency divider circuits; and enabling the frequency divider circuits. The method and system includes enabling the LO buffer to provide the LO signal to the frequency divider circuits after they have been enabled. When the LO signal drives each of the frequency divider circuits, each of the frequency divider circuits starts an operation. Finally the method and system comprise removing the offset voltage from each of the frequency divider circuits to allow them to effectively drive other circuits.

The present invention is directed to a regio- and stereoselective bioconversion of selected aliphatic dinitriles into corresponding cyanocarboxylic acids. More particularly, the present invention provides methods for the conversion of 2-isobutyl-succinonitrile into (S)-3 cyano-5-methylhexanoic acid, which is a useful intermediate in the synthesis of (S)-3(aminomethyl)-5-methylhexanoic acid (pregabalin). Pregabalin can be used for treating certain cerebral diseases, for example, in the treatment and prevention of seizure disorders, pain, and psychotic disorders.

A flexible reinforcement for garments includes a filament that is made of a spring material shaped to have a plurality of turns so as to form an elongated helical spring coil, caps located over the ends of the spring coil; and a cloth channel which receives the elongated coil. The channel is adapted to be sewn into a garment at a location to reinforce its shape. The spring coil may have a diameter of from about 1/32 to 3/16th inches. The caps may be made of plastics, Teflon, metal or similar material and shaped to be round and smooth so as to act to prevent the ends of the spring from penetrating the garment or poking the wearer.

A vibrating headset capable of generating a vibration of variable operational characteristics in the earpiece of the vibrating headset is disclosed. The vibrating headset may include one or more earpieces, each of which includes a speaker and a vibrator mechanism, wherein the vibrator mechanism receives a vibration input signal which is distinct from the audio input signal received by the speaker and defines the variable operational characteristics of the vibration to be generated by the vibrator mechanism. A gaming apparatus including a gaming device and a vibrating headset communicably coupled to the gaming device for generating vibrations of variable operational characteristics in response to receiving a vibration input signal from the gaming device is also provided. Finally, a method of creating vibrations defined by at least one variable operational characteristic in an earpiece of a vibrating headset is provided.

The present invention provides articles of manufacture and methods for making inorganic pigments. In one embodiment, the present invention provides a method for making titanium dioxide, said method comprising: (a) reacting titanium tetrachloride with oxygen in the presence of heat to produce titanium dioxide; and (b) cooling the titanium dioxide in a conduit having a helix, wherein said helix comprises at least one helical bend. Preferably the conduit comprises at least three helical bends, wherein the helix comprises at least three 360 degree spiral turns, and wherein the helix comprises an angle of from one to ten degrees. In a second embodiment, the present invention also provides a helical pipe for manufacturing pigment, comprising a conduit for receiving an inorganic pigment, wherein said conduit comprises a helix and wherein said conduit is capable of withstanding temperatures greater than about 650° C.

A pucker free pocket seam for a shirt providing the shirt with a tailored and wrinkle free appearance. The pucker free seam and method for production utilizes a bonding strip which contains at least a thermal adhesive component which is inserted between folded portions of a first garment component along a seam. A sufficient amount of heat and pressure is applied to the seam which causes the adhesive of the bonding strip to flow onto the surfaces of the folded portions of the first garment component thereby creating a compressed seam and permanently bonding the folded portions of the first garment component together along the seam to eliminate puckering associated with shrinkage of the sewing thread at the seam.
摘要:
A method and system for simulating and verifying a radiation therapy beam prior to treatment. The system also permits the accurate positioning of the beam with respect to the patient. The system utilizes a contour on a prescription image which defines the location and shape of a desired radiation treatment area to generate a transmissive projection which projects the exact field contour onto the patient during simulation. The patient can then be marked with this field contour prior to treatment in the simulation apparatus. With the patient placed in the treatment apparatus the accurate positioning of the patient can be achieved by aligning the patient's skin markings with a light projected through a multi-leaf collimator onto the skin. Furthermore, the correct functioning of the multi-leaf collimator can be verified in this manner since incorrect leaf positions will show up in the light projected onto the patient's skin. The transmissive projection means may comprise, in the preferred embodiment, a liquid crystal display projection device under control of a host computer storing a digitized image of the field contour.
摘要:
A needle having three fluted edges, all of the same angular size. The needle presents a five sided cross-section at a tapered end. This results in easier tissue penetration, reduced cross-sectional needle area, better wound opening area performance, and minimized tissue distortion. In an alternate embodiment, the flat surface from which the taper is formed is on the inside of the needle so that the outer fluted edges are formed outside that configuration.
