Abstract: A method and system are disclosed to detect a broad class of signals including Advanced Television Systems Committee (ATSC) digital television (DTV) and wireless microphone signals. This signal detection method performs in Gaussian noise, employing Higher Order Statistics (HOS). Signals are processed in time and frequency domains as well as by real and imaginary components. The spectrum sensing employed also supports Denial of Service (DoS) signal classification. The method can include parameters that may be tailored to adjust the probability of detection and false alarm.

Abstract: A filling-packaging body formed to have both such a durability that can withstand a large amount of filled material filled therein and easily unsealing property. The filling-packaging body (1) is formed by filling the filled material in a three-side seal bag having an overlapped part formed by cylindrically curving a laminated film (10) and overlapping both side edge parts of the laminated film, a plurality of vertical seal parts (2a) and (2b) (two seal parts are shown) formed at the overlapped part roughly parallel with each other in such a state that a band-like non-seal part (5) is left at the tip side of the outer surface side-edge part of the overlapped part, and lateral seal parts (3) and (4) formed to cross the longitudinal both end parts of the vertical seal parts (2a) and (2b). The laminated film (10) is formed by interposing a base material layer (12) for imparting strength to the film between an inner layer (11) and an outer layer (13) which are seal layers formed of a low density polyethylene.

Abstract: The present invention relates to a magazine for a hand firearm, which is detachably mountable to the weapon, incorporating a drum-like, approximately cylindrical housing (10) which accommodates a greater number of cartridges in an orientation parallel to the axis of the housing, further incorporating an approximately spiral-shaped divider device (9), which is located inside the housing and accommodates the cartridges, a driver plate (14), which is adapted for indexed rotation about its axis and is driven by the force of a spring, said driver plate causing the cartridges to advance to the next position on a spiral path after each shot, and a follower (18) disposed in said magazine, which causes the cartridges to advance on their spiral path, to exit said divider device and to enter into a magazine head (21).

Abstract: A computer-based system and method calculates and facilitates revenue accrual, for making larger, less frequent payments of estimated taxes or other obligations. Payer preferences are applied to satisfy variable payment intervals, amounts, and available resources. The obligation, required payments, and set-aside schedules are recalculated as needed, under payer and/or system control. Excess accruals are minimized; set-aside schedules are configurable. The system may be self-contained, handheld, or accessed remotely. Automatic datalinks move information and command fund transfers from the payer's bank, to accrue funds and make payments to other accounts. A service host may support a plurality of payers to make set-asides and payments at various levels as needed, on an individual or batch basis, including individual taxpayer enrollment for batch file tax payments by service providers. Some embodiments can be embedded to enhance the capabilities of other systems.

Abstract: A method and apparatus are disclosed for managing thermal energy transfer between a mold, die or cavity and a thermal transfer fluid. The thermal energy being exchanged with the mold, die or cavity is calculated in real time as a function of the temperature differential between inlet and outlet fluid temperatures, the volumetric rate of fluid delivery, and known characteristics of the fluid. The rate of thermal energy exchange is controlled by varying the fluid delivery rate in accordance with a desired thermal energy exchange profile.

Abstract: Food service tongs and a mold and method for making them, the tongs having first and second arms connected to a fulcrum end, and first and second grasping ends on the arms disposed in a mutually opposing and spaced-apart relationship and moveable in a common plane to a closed position for grasping food there between, and a transverse bridge disposed proximate to the fulcrum end and extending from the first arm to the second arm, with a longitudinal rib extending from the transverse bridge to the fulcrum end, the flow path through the longitudinal rib section of the mold resulting in reduction or displacement of fault lines caused by abutting flow fronts during mold filling. Articles of the invention can be coated with a thin metallic layer to impart a metal-like appearance to these articles.

Abstract: A system is disclosed for the control of fluid flow in a micro-fluidic system, the system having: a substrate; at least one micro-fluidic channel having disposed in a microchannel layer atop the substrate; a conformable layer disposed on the micro-fluidic layer; a receiving cavity disposed within the at least one micro-fluidic channel; at least one occluding member disposed within the conformable layer, and configured to be received by the receiving cavity so as to occlude the micro-fluidic channel when depressed by an actuator.

Abstract: A rotary floor sanding machine has a vertically oriented bell housing with a backside floor support and a dust suction port for removing dust from within. The bell housing encloses the sides and backside of a disk casing and rotary sanding pad. The floor support is configured to place the floor contact area of the sanding pad forward of center. There is a lifting vane extending from proximate the floor contact area of the sanding pad in the direction of rotation towards the suction port in the bell housing to elevate dust particles to the higher velocity airflow near the suction port. There may be a shield for reducing the floor level opening between the back edge of the disk casing and the bell housing.

Abstract: A digital to analog converter (DAC) method and apparatus employs a multiplying-adding DAC, eliminating digital adder circuitry. Examples are given for multiplying a 3-bit binary number by a 2-bit binary number; however, there are no limitations to the bit-widths of the numbers to be multiplied. The multiplying-adding DAC method can be scaled up or down in bit-width by feeding the DAC with partial sums and adjusting the DAC weights accordingly. An analog to digital converter (ADC) can be placed after the DAC to generate a digital output. By multiplexing preset digital data into the DAC core for return to zero (RTZ), a true zero that is the midpoint of the DAC output range is achieved. It does not return to a rail for single-ended outputs. RTZ in DAC circuits doubles the null frequency of sin(x)/x roll-off inherent in DACs and also helps reduce switching glitches in the DAC output.

Abstract: A quotation system and method are provided (see FIG. 1). A relational database (10) allows various departments (14, 16, 18, 20) to prepare a quotation. The relational database centralizes data to increase efficiency, and the data may be modified, as needed, for particular quotation solutions.

Abstract: An arrangement and a method to control and regulate the bottom hole pressure in a well during subsea drilling at deep waters: The method involves adjustment of a liquid/gas interface level in a drilling riser up or down. The arrangement comprises a high pressure drilling riser and a surface BOP at the upper end of the drilling riser. The surface BOP havs a gas bleeding outlet. The riser also comprises a BOP, with a by-pass line. The drilling riser has an outlet at a depth below the water surface, and the outlet is connected to a pumping system with a flow return conduit running back to a drilling vessel/platform.
