Abstract: A neuristor-based reservoir computing device includes support circuitry formed in a complimentary metal oxide semiconductor (CMOS) layer, input nodes connected to the support circuitry and output nodes connected to the support circuitry. Thin film neuristor nodes are disposed over the CMOS layer with a first portion of the neuristor nodes connected to the input nodes and a second portion of the neuristor nodes connected to the output nodes. Interconnections between the neuristor nodes form a reservoir accepting input signals from the input nodes and outputting signals on the output nodes. A method for forming a neuristor-based reservoir computing device is also provided.

Abstract: Systems and methods for calibrating scanning devices are described. The method comprises dividing a dark scan image of a calibration strip into one or more regions. The dark scan image is further analyzed to obtain at least one data point from each of the one or more regions.

Abstract: A device captures a digital image of a color of interest and a physical color calibration chart. A corrected color value of the color of interest is determined based on the physical color calibration chart and the color of interest as captured within the digital image. A selected color value for the corrected color value is determined, as a closest color value within a predetermined color space or as a spot color value within the predetermined color space.

Abstract: Balancing load distributions of loopback ports includes determining that a load distribution among loopback ports of a switch is unbalanced, determining whether the load distribution is balanceable, and balancing the load distribution.

Abstract: A method of using a buffer within an indexing accelerator during periods of inactivity, comprising flushing indexing specific data located in the buffer, disabling a controller within the indexing accelerator, handing control of the buffer over to a higher level cache, and selecting one of a number of operation modes of the buffer. An indexing accelerator, comprising a controller and a buffer communicatively coupled to the controller, in which, during periods of inactivity, the controller is disabled and a buffer operating mode among a number of operating modes is chosen under which the buffer will be used.

Abstract: A method to enable modification of color characteristics of an image. In the method, an image, defined in a first color space, is transformed to a second color space; and display of the transformed image is controlled. A color characteristic of the transformed image is modified using a rule defined in the second color space in response to a user input, and display of the modified transformed image is controlled.

Abstract: Devices and methods for a communication device having at least one power supply unit coupled to a power connector for providing an operating power for operation of network modules of the communication device and a PoE power for the ports connected to Power over Ethernet (PoE) devices. The PoE power includes a consumable power to power up at least one PoE devices and a leftover power. Further, a PoE power harvester adapter is coupled to a power connector to convert the leftover PoE power into additional operating power for operating additional network modules.

Abstract: A printer mechanism includes a printhead to print on a print medium, and a platen located generally adjacent the printhead such that the platen and the printhead define a print zone therebetween. The platen includes a plurality of elongate ribs that project from an upper surface of the platen in a spaced relationship and positioned to contact a lower surface of the print medium such that the print medium bends downwardly between the ribs to provide an undulated section of the print medium with hills and valleys in the print zone. At least one shape control mechanism transforms each of the hills in the print zone into a corresponding valley in an output path adjacent to the print zone and transforms each of the valleys in the print zone into a corresponding hill in the output path.
