Abstract: An internet browser software component facilitates online submission of prescription eyeglass orders by receiving frame trace data sent to a computer by a frame tracer and embedding it in an order form prepared for submission over the internet. The browser software component may interpret data sent to any peripheral port on the computer, including serial (COM) ports, Universal Serial Bus (USB) ports, and Ethernet ports. The browser software component embeds the frame trace so that it is sent in the same logical packet as the rest of the prescription order. The browser software component may also create a graphical representation of the frame trace and display it in a graphical user interface containing the order form so that the prescription order may be easily reviewed for accuracy before submitting it to be processed.

Abstract: In an encoding process, video data are represented as a bitstream of a quantized base layer and one or more enhancement layers, which capture the difference between a quantized base video picture and an original unquantized input video picture. Due to bandwidth constraints on a communication channel, it may be unfeasible to transmit all enhancement layers. During the encoding process, the enhancement layer data may be adjusted to give transmission priority to information in the enhancement layers that is visually important. Following transmission, the adjustment may be undone during the decoding process.

Abstract: A video encoding method and apparatus for adapting a video input to a bandwidth of a transmission channel of a network that includes determining the number N enhancement layer bitstreams capable of being adapted to the bandwidth of the transmission channel of a network. A base layer bitstream is encoded from the video input wherein a plurality of enhancement layer bitstreams are encoded from the video input. The enhancement layer bit-streams are based on the base layer bitstream, wherein the plurality of enhancement layer bitstreams complements the base layer bitstream and the base layer bitstream and N enhancement layer bitstreams to are transmitted to the network.

Abstract: The enlarging system includes a projection housing for receiving a negative film insert device supporting an anamorphic negative film image which is projected towards a working surface. Below the insert device is a projection lens, lens adapter, anamorphic lens secured in the adapter, and a dioptor lens. A light bellows connects between the projection lens and the negative film insert device. A first adjustment is used to vary the distance of the entire projection housing and lens system towards and away from the working surface. A second adjustment, in turn, varies the distance of the lens system from the negative film insert device. The dioptor in combination with the anamorphic lens permits a selected format size for the enlarged print to be chosen, the first adjustment matching perfectly the projected image with the selected format. The second adjustment brings the image into a fine focus.
