    Abstract: Techniques for improving image quality of a HDR image by increasing the contrast in the dark portion of the image while preserving the bright parts of the image. The methods preserve the input dynamic range. An image with a luminance histogram gap between a main portion with low brightness and a small portion with high brightness. A first tone mapping curve is determined for the low brightness portion of the image. A second tone mapping curve is determined from a selected point on the first tone mapping curve to a maximum brightness level of the input image. A final tone mapping curve is generated including the first tone mapping curve from a minimum brightness input to the selected point and the second tone mapping curve from the selected point to a maximum brightness level. The method can increase overall image quality and contrast.

    Abstract: Systems, methods, and computer-readable media are provided for wireless sensor networks (WSNs), including vehicle-based WSNs. A road side unit (RSU) includes one or more fixed sensors covering different sectors of a designated coverage area. The RSU uses the sensors to capture sensor data that is representative of objects in the coverage area, tracks objects (e.g., vehicles) in the coverage area, and determines regions in the coverage area that are not adequately covered by the sensors (e.g., “perception gaps”). When the RSU identifies an object that is in or at a perception gap, then the RSU sends a request to that object for sensor data captured by the object's on-board sensors. The RSU obtains the sensor data from the object, and uses the obtained sensor data to complement the knowledge that the RSU (i.e., “filling the perception gaps”). Other embodiments are disclosed and/or claimed.

    Abstract: A transmitter for chip to chip communication may include a modulator and a transmit frequency converter. The modulator may modulate a first received signal according to a first modulation scheme. The modulator may also modulate a second received signal according to a second modulation scheme. The transmit frequency converter may center the first received signal on a first frequency that does not comprise a phase within a radio frequency (RF) domain to generate a first centered signal. The transmit frequency converter may also center the second received signal on a second frequency that comprises a phase within the frequency band to generate a second centered signal. The second centered signal may be orthogonal to the first centered signal. A frequency gap may be positioned between the first centered signal and the second centered signal within the frequency band.

    Abstract: Embodiments of the present disclosure are directed to multi-wavelength laser generator may produce light with a frequency comb having equally spaced frequency lines. In various embodiments, the laser generator includes first, a semiconductor gain element is used to provide gain to the laser being generated. Second, a ring resonator filter, or ring filter, is used to select the wavelength comb spacing. Third, a narrow-band DBR or narrow-band mirror is used to select the number of wavelengths that lase. Fourth, a wide-band or narrow-band mirror is used to provide optical feedback and to form the optical cavity. Fifth, a phase tuner section is used to align the cavity modes with the ring resonances (i.e. the ring filter modes) in order to reduce or minimize the modal loss. Other embodiments may be described and/or claimed.

    Abstract: Techniques and mechanisms for determining a relative order in which a load instruction and a store instruction are to be executed. In an embodiment, a processor detects an address collision event wherein two instructions, corresponding to different respective instruction pointer values, target the same memory address. Based on the address collision event, the processor identifies respective instruction types of the two instructions as an aliasing instruction type pair. The processor further determines a count of decisions each to forego a reversal of an order of execution of instructions. Each decision represented in the count is based on instructions which are each of a different respective instruction type of the aliasing instruction type pair. In another embodiment, the processor determines, based on the count of decisions, whether a later load instruction is to be advanced in an order of instruction execution.
