A rotor is disclosed for a galvanometer system. A rotor includes a permanent magnet core, a sleeve and at least one shaft unit. The sleeve encloses and attaches to at least a portion of the permanent magnet core. The sleeve is formed of a material having a density of less than about 0.283 lb/in3. The shaft unit is attached to both the permanent magnet core and to the sleeve. An output device may be coupled to the shaft unit, and the shaft unit is formed of a material having a dynamic stiffness of at least about 1.00×109 lb in7/slug.

A method of forming an integrated circuit and a structure therefore is provided. A gate dielectric is formed on a semiconductor substrate, and a gate is formed over the gate dielectric. Shallow source/drain junctions are formed in the semiconductor substrate. A sidewall spacer is formed around the gate. Deep source/drain junctions are formed in the semiconductor substrate using the sidewall spacer. A siliciding spacer is formed over the sidewall spacer after forming the shallow and deep source/drain junctions. A silicide is formed on the deep source/drain junctions adjacent the siliciding spacer, and a dielectric layer is deposited above the semiconductor substrate. Contacts are then formed in the dielectric layer to the silicide.

The present invention relates to a method for decreasing elevated serum/plasma LDL-cholesterol levels or LDL-cholesterol levels and CRP levels in a mammal in need thereof. The methods comprises administering an effective amount of a tetracycline formulation. In one embodiment, the tetracycline formulation is a non-antibacterial tetracycline. In another embodiment, the tetracycline formulation is an antibacterial tetracycline at a sub-antibacterial amount.

A MEMS based thermoacoustic cryo-cooler for thermal management of cryogenic electronic devices. The cryogenic cooling system can be integrated directly into a cryogenic electronic device. A vertical comb-drive provides an acoustic source through a driving plate to a resonant tube. By exciting a standing wave within the resonant tube, a temperature difference develops across a stack in the tube, thereby enabling heat exchange between heat exchangers. A tapered resonant tube improves the efficiency of the cooling system, compared with a simple cylinder configuration, leading to reduced harmonics and strong standing waves.

A system and method is described for manipulating text relative to a curved reference line in order to transform a character, rendered in a particular font, to generate a warped character with the degree of warping reflecting the local curvature of the curved reference line. The curvature of the reference line is reflected in the nature of quadilaterals, i.e., quads, generated for a corresponding rectangle on a straight reference line. The coordinates of the corners of the quad provide the parameters to carry out the transformation. Such rendering improves the appearance of the text and provides a method that modifies available fonts in a flexible fashion without the need to generate new fonts.

A full-time power transfer system is disclosed to include a transfer case having a clutch assembly arranged to control speed differentiation and torque biasing across an interaxle differential, sensors for detecting and generating sensor signals indicative of various dynamic and operational characteristics of the vehicle, and a controller for controlling actuation of the clutch assembly in response to the sensor signals. Upon the occurrence of traction loss, the clutch assembly is automatically actuated for limiting interaxle slip while transferring increased drive torque to the non-slipping driveline. Under a preferred adaptive control scheme, the actuated condition of the clutch assembly is controllably modulated between its non-actuated and fully-actuated limits for automatically varying the magnitude of speed differentiation and torque biasing across the interaxle differential in response to changes in the dynamic and operational characteristics of the vehicle.

A transmission for a four-wheel drive vehicle having a multi-speed geartrain and power transfer mechanism incorporated into a common housing assembly. The multi-speed geartrain includes a input shaft, a mainshaft, and a plurality of constant-mesh gearsets arranged for selectively coupling the mainshaft to the input shaft for driven rotation at various speed ratios. The mainshaft can be selectively coupled to the power transfer mechanism for establishing two alternative power transmission routes. In particular, a range shift mechanism is provided for establishing a high-range power transmission route and a low-range power transmission route from the mainshaft to the input of an interaxle differential. The torque delivered to the interaxle differential is split between the front and rear drivelines to establish a full-time four-wheel drive mode. A transfer clutch is provided for automatically controlling slip and torque biasing between the outputs of the interaxle differential.

In a database data processing system, input search data is matched against an index of a database to determine database records which either closely or exactly match the input search data. The input search data is broken down into elements, and elements are converted to terms having a finite set of possible values. The Soundex function may be used to convert elements to terms. The terms are compared against an index of terms to determine which database records relate to the input search data. Through statistical analysis, match records are given a record weight which may be used to calculate how closely the input data actually is to each match record. The invention provides a fast and efficient way of accurately searching for data in extremely large databases, while not requiring precise input search data entry. The invention may also be used to compare or supplement one database against another.
