Abstract: A method and apparatus is proposed for accurately evaluating the performance of optical transmitters under test conditions (such as high bit-rate modulation formats) that compromise the operability of standard test equipment used for this purpose. The proposed apparatus and method are similar to the elements associated with existing testing standards based on an optical eye diagram, with an important distinction that allows for accurate measurements of the transmitter's performance to be made. In particular, the sampling point for collecting eye diagram data samples in the inventive arrangement is shifted by half a period with respect to the conventional mid-eye sampling point, eliminating the need to include representative reference equalizer in the test equipment and providing an evaluation not influenced by the test equipment, resulting in a more accurate measurement of transmitter-related distortions.

Abstract: A fixing device includes a fixing member, a pressurizing member, a charging portion, and a control portion. The fixing member rotates while being heated. The pressurizing member forms a nip portion between itself and a surface of the fixing member in such a way as to hold a sheet therebetween and conveys the sheet by rotating together with the fixing member, wherein an image of toner has been formed on the sheet. The charging portion electrically charges the surface of the fixing member to a polarity that is same as a charging polarity of the toner by supplying a charging current to a pair of electrodes that is disposed to face the surface of the fixing member. The control portion derives an index value of a charge amount of the toner on the sheet, and adjusts the charging current based on the index value.

Abstract: A transformer economizer automatically disconnects a main electric power transformer from a grid power line during low-load periods, and automatically reconnects the main transformer to the grid power line during high-load periods, to reduce low-power electricity losses incurred by the main transformer. The main transformer is therefore deenergized and a much smaller auxiliary transformer is energized during low-load periods to reduce the low-power electricity losses incurred by the main transformer. The main transformer is then automatically switched back into service during high-load periods, while the auxiliary transformer is switched out of service. This provides long-term energy, cost, and carbon footprint savings by automatically switching the large transformer's loads to a much smaller auxiliary transformer, and therefore proportionally lower losses, during light-load conditions.

Abstract: Systems and techniques for protocol buffer trie packing and streaming updates are described herein. Data entities are identified in a received update query. An index value is assigned to each unique data entity to generate an index of unique data entities. A frequency of occurrence value is determined for each unique data. entity. The index of unique data entities is sorted by data entity type in descending order by the frequency of occurrence value of each unique data entity. A trie is generated with a root node assigned as a first unique data entity from the index of unique data entities that has a frequency of occurrence value with the largest numerical value. An update payload is created for the trie by conversion of the trie into a protocol buffer format through serialization of the trie into a binary string.

Abstract: A header for a heat exchanger and method for cleaning a heat exchanger in a loop without disconnecting loop components is provided. The header is in flow communication with the heat exchanger for distributing fluid through a plurality of adjacent channels. The header is connected between a main heat exchanger inlet nozzle and a channel flow distributor. A filter element is disposed within the header between the nozzle and channel flow distributor. Under normal operation, the filter element removes particulates and fouling material from the main flow stream before it enters the heat exchanger channels. During the cleaning process, fluid is injected on or through the filter element to remove particulates and fouling material through at least one outlet port. The header arrangement allows the filter element to be ‘cleaned in place’ without draining the system and disconnecting the heat exchanger or other components from the flow loop.
