Abstract: The invention provides a curved-slit imaging spectrometer, wherein a fiber bundle transfers a straight line image of a front objective lens to a curved slit, and the front objective lens doesn't need to have a curved image plane to directly abut the spectrometer, so that the system is less complicated, and the front objective lens and spectrometer have a simple structure. The arc-shaped or approximately arc-shaped curved slit matches the optimum imaging circle of the Offner-type spectrometer, thereby achieving an extra-long slit. The arced slit is 5 to 10 times longer than the straight slit of the classical Offner-type spectrometer. In the case of a compact size, the length of the slit can be greater than 100 mm. Also, the same spectral response function applies in different fields of view while presenting desirable imaging quality.

Abstract: An LED bulb includes a center ring, a burner and an elastic component. The center ring includes a central opening, a first flat rim extending along a first part of an outer edge of the central opening, and a first notch cut-out beyond the central opening at an end of the first flat rim. The burner is disposed at least in part in the central opening and includes a first pin that has a first flat side face. The elastic component is configured to press the first flat rim of the center ring against the first flat side face of the first pin of the burner.

Abstract: A method of graphics processing comprising receiving, at a graphics processing unit (GPU), a command stream, the command stream including one or more commands to be performed by the GPU and at least one command stream hint, the at least one command stream hint providing a characterization of a workload of the command stream, performing, by the GPU, a power management process based on the at least one command stream hint prior to executing the command stream, and executing, by the GPU, the command stream.

Abstract: Techniques are described in which a processor determines how busy a graphics processing unit (GPU) was in rendering a current fame based on a time interval between when the GPU completed the rendering of the current frame and when the GPU completed the rendering of a previous frame that immediately precedes the current frame. The processor sets a clock rate of the GPU based on the determination of how busy the GPU was in rendering the current frame.

Abstract: A DC conversion device including a first DC converter and a second DC converter connected in series, a voltage difference adjusting unit, and a first and a second control unit is provided. The first and the second DC converter respectively receive a first and a second input current to generate a first output current and a first output voltage, a second output current and a second output voltage at a first and a second output end connected to a first and a second energy-storing element, respectively. The voltage difference adjusting unit generates a voltage difference adjusting signal. The first control unit generates a first control signal to control the first converter. The second control unit generates a second control signal according to the voltage difference adjusting signal to control the second converter to balance the first and the second input and output voltages.

Abstract: Methods, systems and processor-readable media for reducing the width of a logical comparison. A width of a logical comparison based on a previous result generated can be recursively reduced from a data stream and a maximum count of consecutive ones or consecutive zeros determined from the serial data stream based on a priority encoder within a single clock cycle in order to avoid a use of complex functions. In this manner, the maximum number of the consecutive ones or the consecutive zeros in a parallel word bus within the single dock cycle can be ascertained.
