Abstract:
The performance of a service technician who performs multiple service dispatches is evaluated by comparing the service technician's actual times to perform a series of tasks that make up a dispatch, to planned times for the series of tasks. Statistically derived planned times may be assigned to tasks that make up a dispatch, so that an objective work measurement and evaluation may be provided.

The present invention relates to the field glycosylation engineering of proteins. More particular, the present invention is directed to the glycosylation engineering of proteins to provide proteins with improved therapeutic properties, e.g., antibodies, antibody fragments, or a fusion protein that includes a region equivalent to the Fc region of an immunoglobulin, with enhanced Fc-mediated cellular cytotoxicity.
Abstract:
A flat table extension is removably attached to one end of an operating table via a support mechanism that is connected with one of the operating table support legs.The support mechanism includes a pair of support posts, one of which is rotated from a first position parallel with the operating table to a second position lower than the operating table to lower the table extension as required.

An electronic menu and concierge system (100) for the travel and hospitality industry. The electronic menu and concierge system (100) is a centralized, Internet-hosted service that is accessible by hotel guests and visitors. The system may provide hotel information, such as hotel events (162), directions (248), and local attractions (166). Food and/or beverages services (270) and merchandise may also be ordered through the system (100).
Abstract:
A modular surgical patient positioner unit consists of three perforated plastic boards arranged for interconnection together and for attachment to a hospital O.R. table. Two outer boards of similar length and width and a central board of similar width and greater length are employed. When employed with regular-sized patients, the three boards are arranged such that the widths thereof are in alignment. When employed with bariatric patients, the longer central board is rotated perpendicular the other two boards, to provide added width to support the bariatric patient.
Abstract:
Error diffusion is performed using a Floyd-Steinberg-like approach. A integer-representation of a running error is compressed by storing only its most significant bits and returning any remainder to the error diffusion processor. The running error is shifted to the right until only the desired number of significant bits remain, and this compressed error is stored. Any portion of the original running error that is lost due to the shifting is treated as a remainder and is returned to the error diffusion processor for use in calculating an adjusted current pixel value. The amount of the shift is retained in compressed form to keep track of the number of shifts needed to form a truncated running error from the compressed running error.
Abstract:
Pixel data-driven error diffusion is performed by using two lookup tables. The first table receives a non-binary pixel value and outputs a selection signal in response thereto. The selection signal serves as a pointer to entries in the second table where coefficients associated with a set of error spread weights are stored. In this manner, each non-binary pixel value is mapped onto a handful of predetermined sets of error spread weights to be used in an error diffusion calculation. The first table, the second table and an associated error diffusion processor can all reside on a common integrated circuit. A third table can also be indexed at the same time to provide randomization information to be used in calculating a dynamic threshold for used in a half-toning process for the corresponding pixel.
Abstract:
A method, and a document scanning apparatus employing the method, of scanning with a light source. The method comprises the acts of determining a calibration time of the light source and light sensor in a scanning unit, adjusting an activation time for the light source based on the calibration time, scaling a clock signal based on the activation time, and activating the light source based on the scaled clock signals. Where a red, green and blue LED light source is used, the longest of the activation times of the LEDs is used for the scaling of the clock signals. In another embodiment, the time between the start of the activation of last LED scan on a previous scan line and the start of activation of the first LED on the subsequent scan line is adjusted to maintain the predetermined resolution used for the scan.
Abstract:
The present invention is directed to a system and method for reducing the memory requirement for offset and gain calibration to relieve the size/performance bottleneck in scanner systems. The resulting methodology produces visually equivalent scanned results with a substantial increase in performance, which results in a shorter amount of time required to output a first copy in, for example, an all-in-one device. Since the calibration step is often the bottleneck in scanner performance, this method noticeably speeds up scan and copy time. Implementing the decompression in hardware requires a minimal amount of hardware overhead and complexity. Thus, this method has a minimal impact on the size and cost of the scanner controller (e.g., an ASIC—application specific integrated circuit). Since compression only takes place at most once per scan, this added step has no significant impact on the overall scan time. By allowing dynamic grouping of pixels using a single calibration packet, the quality of the compensation can be optimized with the size of the compensation data being minimized. Adding the ability to shift the compressed deviation stored in the calibration packet, the range of the pixel-to-pixel deviation can be increased without impacting the size of the calibration data. This flexibility makes this invention applicable to future image sensors that may have widely varying deviations in pixel-to-pixel offset and gain values.
