Abstract: An imaging device (1) includes a positron emission tomography (PET) scanner (10) including radiation detectors (12) and coincidence circuitry for detecting electron-positron annihilation events as 511 keV gamma ray pairs defining lines of response (LORs) with each event having a detection time difference At between the 511 keV gamma rays of the pair. At least one processor (30) is programmed to reconstruct a dataset comprising detected electron-positron annihilation events acquired for a region of interest by the PET scanner to form a reconstructed PET image wherein the reconstruction includes TOF localization of the events along respective LORs using a TOF kernel having a location parameter dependent on At and a TOF kernel width or shape that varies over the region of interest. A display device (34) is configured to display the reconstructed PET image.

Abstract: Disclosed is a method of locking a locked loop quickly, including receiving an input signal having an input frequency, and generating an intermediate signal having an intermediate frequency intended to be equal to a geometric mean of the input frequency and a desired frequency, but not equal. Results of division of the desired output frequency by the intermediate frequency are estimated, producing a first divider value. A first locked loop utilizing a controllable oscillator is activated. A divider value of the first locked loop is set to the first divider value, and the intermediate signal is provided to the first locked loop, so that when the first locked loop reaches lock, the controllable oscillator produces the desired frequency. When the first locked loop reaches lock, a second locked loop that utilizes the controllable oscillator is activated, the first locked loop is deactivated, and generation of the intermediate signal is ceased.

Abstract: To enable better encoding of the currently starting to appear high dynamic range images for use in full high dynamic range technical systems (containing an HDR display, and e.g. in an HDR grading application), we invented a method of constructing a code allocation function for allocating pixel colors having pixel luminances to codes encoding such pixel luminances, in which the step of determining the code allocation function to be applied to at least one color coordinate of the pixel to obtain a code value, comprises constructing that function out of at least two partial functions, and similar methods at a receiving side, and apparatuses, and signals for communicating between the two sites. This method allows—in line with applicant's technical approach that HDR images should actually be communicated as a spectrum of differently regraded different dynamic range images of the same scene, e.g.

Abstract: A method of measuring a position of an alignment target on a substrate using an optical system. The method includes measuring a sub-segmented target by illuminating the sub-segmented target with radiation and detecting radiation diffracted by the sub-segmented target using a detector system to obtain signals containing positional information of the one sub-segmented target. The sub-segmented target has structures arranged periodically in at least a first direction, at least some of the structures including smaller sub-structures, and each sub-segmented target is formed with a positional offset between the structures and the sub-structures that is a combination of both known and unknown components. The signals, together with information on differences between known offsets of the sub-segmented target are used to calculate a measured position of an alignment target which is corrected for the unknown component of the positional offset.

Authentication and authorization includes generating a profile for a device based on at least one characteristic observed during a successful attempt by the device to access an 802.1X network infrastructure. Expected characteristics for a next attempt to access the infrastructure by the device are determined. A characteristic of the next access attempt is matched to the expected characteristic and access to the network is selectively controlled as a result of the matching. This is achieved without a supplicant being installed on the device.

Abstract: A laser lighting system has a first laser light source, a second laser light source and a light conversion element. The outputs from the first and second laser light sources are directed to the light conversion element, which generates wavelength-converted light output in response to excitation by laser light. The first and second laser light sources generate laser light of different wavelength having different absorption characteristics within the light conversion element, such that the range of depths within the light conversion element from which wavelength-converted light is generated is different. This difference in converted output can be used to create different optical effects so that beam steering or beam shaping can be performed.
