Abstract: A viscous material noncontact jetting system has a jetting dispenser mounted for relative motion with respect to a surface. A control is operable to cause the jetting dispenser to jet a viscous material droplet that is applied to the surface as a viscous material dot. A device, such as a camera or weigh scale, is connected to the control and provides a feedback signal representing a size-related physical characteristic of the dot applied to the surface. The size-related physical characteristics of subsequently applied dots is controlled by heating and cooling, or adjusting a piston stroke in the jetting dispenser, in response to the size-related physical characteristic feedback. Dispensed material volume control and velocity offset compensation are also provided.

Abstract: A dipole array assembly, is disclosed which includes a plurality of poles arranged in a two-dimensional array to provide a plurality of dipoles, each pole being shaped such that adjacent edges of neighbouring poles that are from respective neighbouring dipoles are relatively long and relatively close to each other compared to the dimensions of the poles, thereby increasing coupling between different dipoles. A feed arrangement is provided in a plane that is at an angle to the plane of the dipoles wherein one or more baluns are integrated in the feed arrangement. Dual polarised operation can be performed independently between the two polarisations.

Abstract: This disclosure provides systems, methods and apparatus including computer programs encoded on computer storage media for producing line multiplied images with better visual appearance. In one aspect, before lines of the image are multiplied, they are dithered with a noise signal that increases faster with higher frequency along the multiplied dimension of the image data than along the non multiplied dimension of the image. This results in a line multiplied image was improved image quality.

Abstract: Embodiments of a method and system for payment funding are provided. A funding specification request is received that defines a plurality of payment sources and a priority for the plurality of payment sources for making payments in a networked system. A determination as to whether a payment allocation is received in the funding specification request that designates an allocation of a portion of an amount of value to be provided by a plurality of users for a transaction conducted through the networked system is made. Based on the determination that the payment allocation is not received in the funding specification request, a default payment allocation to be provided by the plurality of users is identified. A payment for at least the portion of the amount from at least one of the plurality of payment sources based on the priority indicated in the funding specification request is processed.

Abstract: An antenna assembly is disclosed which includes a layered structure having a planar array of antenna elements; and a feed arrangement perpendicular to the antenna elements; the layered structure further having layers over the planar array of antenna elements with holes provided therethrough to allow the feed arrangement to be connected to contacts for the antenna elements. The layered structure may include vias provided such that heat may be applied remotely to the contacts.

Abstract: Systems, methods and apparatus including computer programs encoded on computer storage media optimize display image quality under a variety of imaging environments. Dynamic frame streams such as those present in video applications may require a higher frame rate to adequately convey motion in the stream. A line multiplying image pipeline may be utilized for dynamic frames, which lowers the resolution of the displayed image. When dithering line multiplied images, a noise signal including asymmetrical high frequency components around zero frequency may be utilized. The display of static frames, such as photographs, may be achieved with acceptable image quality using a relatively lower display frame rate. Such a frame rate may enable the display of a high resolution image. A noise signal tailored for higher resolution, non line multiplied frames, such as a noise signal with symmetric high frequency components around zero frequency may be utilized for static frames.

Abstract: A method for electronic commerce management is provided. The method includes sending a request to the test server to be assigned a session identifier, the session identifier being associated with an assigned content version and receive the session identifier from the test server. The method further includes generating web page data to send to the client program, the web page data including (1) computer code which upon execution will cause the client program to retrieve the assigned content version of the static content from the test server using the session identifier, and (2) dynamic web page content based on one or more dynamic content factors and send the web page data to the client program.
