An Internet-based optical imaging system to gather anthropometric data for the purpose of enabling national and international commerce in the wearable goods market, including accurate measurement for selecting, fitting, and ordering eyeglasses and eyeglass frames via the Internet that includes vendor support interaction. A customer can view and orient his or her real-time image, wear a sales item on a virtual personal model, and order selected sales item via the Internet access. The customer's 2-D photoimagery/textured 3-D model and logistics data are acquired at a modeling kiosk that, for eyeglasses, includes specific vendor specification items, pupilary, bridge, and temple distances necessary for a specific customer. Internet data paths from the modeling kiosk node to vendor nodes, such as point-of-sale and manufacturers, and the customer's home computer, can-be provided. The system uses at least one digital camera and least one pattern projector to obtain 2-D/3-D imaging simultaneously with the interaction and use of texture generation for extremely accurate measurements.

A method for analyzing and designing structures with structural aliasing. The concept of structural aliasing applies in one embodiment of the present invention to structural systems which are cyclically symmetric. In analyzing and designing structural systems such as wheel assemblies of gas turbine engines, it is possible to group the discrete components so as to aliasingly couple particular ordered excitations and harmonic families. With structural aliasing, it is possible to couple the ordered excitations and harmonic families such that resonant response of the wheel assembly does not occur within the operating range of the engine, and also to have the resonant vibratory mode excited in such a manner that the drive coupling of the wheel dampens the wheel assembly.

A computerized system and method for inspecting and measuring a ball-shaped wire bond formed by an automated bonder pre-programmed to attach a connecting bond onto a bond pad of an integrated circuit by first obtaining a first image of said bond pad before bond attachment, then determining the coordinates of the center of said pad. Second, the bonder is instructed to attach a ball-shaped wire bond to the center of said pad. Next, a second image of said bond pad is obtained after bond attachment; this second image comprises an image of the ball-shaped portion of the bond and an image of the wire portion of said bond. The coordinates of the center of the ball-shaped portion of the bond are obtained by computer processing of the first and second images. The coordinates of the bond center and the pad center are compared, creating information for quality control of the bonder instruction and the bonding process. Finally, the bond process quality is controlled by inputting new bonder instruction for correcting any identified differences between the center coordinates.

It is an object of the present invention to provide an arithmetic logic unit that can perform a sum-of-products operation in a reduced number of processing cycles without carrying out data transfer and additions even in obtaining a single result from a plurality of divided input data words. Data words X and Y are input. A product of the high-order bits of X and Y is calculated using first decoder 511, first selector 521, first partial product generator 531 and first full adder 541. A product of the low-order bits of X and Y is also calculated using second decoder 512, second selector 522, second partial product generator 532 and second full adder 542. These products are adaptively shifted at a shifter 55 and then added up with a fed back data word Z at a third full adder 56 and a carry-propagation adder 58. In this manner, the data word Z, representing the result of the sum-of-products operation, is obtained.

The floating point number data processing means is for use in microprocessor systems and finds application in AC motor drive technology. The format used includes a sign bit, a seven bit signed exponent and an eight bit mantissa. The mathematical functions are performed in a gate array using registers which are mapped into a memory of the microprocessor system, the particular mathematical function being dependent upon a particular choice of registers. An unsigned integer comparison of floating point numbers is used to give a correct result.

A low latency fused multiply-adder for adding a product of a first binary number and a second binary number to a third binary number is disclosed. The low latency fused multiply-adder includes a partial product generation module, a partial product reduction module, and a carry propagate adder. The partial product generation module generates a set of partial products from the first binary number and the second binary number. Coupled to the partial product generation module, the partial product reduction module combines the set of partial products with the third binary number to produce a redundant Sum and a redundant Carry. Finally, the carry propagate adder adds the redundant Sum and the redundant Carry to yield a Sum Total.

A programmable and configurable datapath unit (DPU) includes a configuration of single-bit multi-function processing units (PUs). The DPU can perform any of a variety of functions depending on the control applied to each PU. Functionality can be increased by utilizing multiplexers to direct data into, out of, and through each DPU dependent on the selected function being performed. Datapath units can also be configured and interconnected to form larger datapath circuits, arrays, and systems so as to increase the data throughput of the datapath system. A configurable and programmable datapath array includes rows of datapath units which can be interconnected to provide DPU circuits having varying input operand widths and functions. A datapath system can be constructed with a plurality of arrays of DPUs to further increase system data throughput.
