Abstract: Addressed herein are techniques and equipment for pre-processing digital images to be superimposed for display. Filtering, re-sampling, and decimation are variously used to process images and sub-images to produce to-be-superimposed images. One of the described techniques is designed primarily (although not necessarily exclusively) for computational efficiency, while the other sacrifices some computational efficiency for higher quality of output images.

Abstract: An electronic projector has a projection system that includes a spatial light modulator (SLM) for importing image information to the projected light beam. The light beam leaving the SLM is prepolarized in a defined orientation and the projected light is polarized in the same orientation so as to effectively block any light that has been scattered within the projector and become depolarized. The SLM may be a digital mirror device (DMD). Reflective surfaces within the projector may be covered or coated with material that alters the polarization of reflected stray light from the defined orientation or depolarizes the reflected stray light.

Abstract: Apparatuses and methods are provided for cutting a traveling web of paper that is being spooled on a full spool and transferring the paper web to spool on an empty spool by driving turn-up tape into a nip between the empty spool and the paper web. The apparatuses and methods provide a more problem free way of transferring a traveling paper web to an empty spool.

Abstract: The system provides a method for gathering and sending monitored traffic data via a short messaging system message over a wireless network through a publicly switched telephone network (“PSTN”) to a central computer. A remote traffic monitoring unit acts as a data collection device collecting data regarding the traffic count and other conditions at its particular location. The remote traffic monitoring unit can monitor different types of traffic—for example, motor vehicles, trains, and pedestrians. The system routes data messages including monitored traffic count data from the remote traffic monitoring unit to a central computer and routes control information from the central computer to the remote traffic monitoring unit.

Abstract: A carpet sample book is provided which is constructed from a single sheet of material, such as cardboard. Tab and slot fasteners are used to avoid the need of adhesives. The samples are supported in the facing pages of the book by slots which are cut into the cardboard surface. The slots are cut in a “C” shape which allows the samples to be held at an angle.

Abstract: A deformable mirror device having a two-dimensional array of mirror elements is driven in such a way to reduce the data rate and remove the need for buffer stores. The mirror elements are loaded row-by-row in response to an n bit video signal in 2n loading operations. Only n rows are loaded in each loading operation, the other rows remaining in their previous conditions, and the loading continues sequentially down the array. The timing of the loading is such that the duration from loading a given row with a first data bit to loading the same row with the next data bit is proportional to the significance of the first data bit.

Abstract: The present invention provides automated systems for performing electrostatic discharge (ESD) device efficacy monitoring and recording the results for an ESD auditing program. Systems of the present invention comprise at least one ESD device monitoring unit. A communication system allows the monitoring unit to communicate with a central computer which collects, stores and allows the manipulation of the test data. Systems of the present invention are therefore useful in testing the ESD devices, documenting their performance, and controlling access to particular work areas based on testing results.
