The system also includes a spatial light modulator (SLM) coupled to the controller. The SLM is configured to project an image of the image frame according to the dithered bit planes. Additionally, the system includes a light source optically coupled to the SLM. The light source is configured to provide light for projecting the image.

Abstract: A system includes a memory and a display. The system also includes a processor coupled to the memory and to the display. The processor is configured to obtain an image and determine a parent cluster of pixels of an image having a centroid. The processor is also configured to split the parent cluster into at least a first child cluster and a second child cluster and assign a pixel of the image to the first child cluster. Additionally, the pixel is configured to update a centroid of the first child cluster responsive to the pixel and replace the pixel in the image with the centroid of the first child cluster to produce a compressed image. Also, the processor is configured to store the compressed image in the memory, where the display is configured to display the compressed image.

The image data is associated with a color component of the image frame. The controller also includes a dither noise mask generator configured to provide dither noise masks according to dither noise levels for the image data, and a bit plane generator coupled to the frame memory controller and the dither noise mask generator and configured to generate bit planes based on the dither noise masks for the image data.

Abstract: Extracorporeal blood treatment systems and methods to display status information for one or more fluids used in extracorporeal blood treatments. For example, a graphical user interface may include a fluids region depicting one or more fluid areas. Each fluid area may include pump and reservoir elements that depict flow rate information, reservoir volume information, and/or a notification related thereto.

Abstract: One aspect provides a method of controlling transmit power in a wireless device, wherein a desired transmit power is determined as a result of detection of a receive signal parameter. The method comprises detecting a desired maximum transmit power and generating a sequence of attenuation factors. The sequence is generated by monotonically increasing a variable at a controlled rate between a starting value and the maximum transmit power. The method further comprises using each attenuation factor in turn to: (a) reduce the measured value of the received signal power; and (b) reduce a determined desired value of the transmit power, where the transmit power is continually reduced as the variable is increased.

Abstract: A network of nodes and connections is provided, each connection connecting two nodes. A method of operating a first node in the network includes detecting a change in a node connected to the first node, identifying that the number of nodes connected to the first node with the detected change is above a predetermined threshold, and executing the detected change at the first node and/or propagating the detected change to one or more nodes connected to the first node that do not have the detected change.

Abstract: The present invention provides a droplet generator (10) of the velocity modulation type, the generator (10) being configured so that substantially all the modulation energy generated by piezo-electric crystals (60) is transformed into vibration of the nozzle (34). The generator preferably also includes an internal closure mechanism (70) which blocks off the nozzle (34) when the generator is not in operation, but which is de-coupled from the modulation process when the generator is operating.

Abstract: An input signal is mixed with a scrambling code and with an OVSF code, and then accumulated over a period of time equal to one symbol of the pilot channel before being reset. The resultant complex signals are mixed with the conjugate of complex signals provided by a pilot pattern generator, with the result being fed to a delay line (22). A multiplier multiplies the complex value at a location P(n) in the delay line (22) by the conjugate of a complex value at another location P(n+k), and provides the resulting complex number (which is a complex vector whose phase is a coherent measurement of the phase rotation occurring between the symbols corresponding to the two locations) at an output (27). The real part of the complex signal provided at the output (27) is provided to a first combiner (30), and the imaginary part is provided to a second combiner (31). These combiners (30, 31) also receive corresponding signals from all of the other fingers (not shown) of the rake receiver.
