A target device's location in a radio network is estimated by maintaining a probabilistic model for several sample points that indicate expected distributions of signal values at a given location. The target device observes signal values, wherein the sequence of observations and the respective locations constitute a Hidden Markov Model. A graph models the topology of the positioning environment. The graph indicates several nodes which are permissible locations in the environment and several arcs which are permissible transitions between two nodes. The graph is used to estimate the target device's location based on the probabilistic model and the sequence of observations.

A camera is configured to capture an image of a real world scene as an image signal and to store captured images. The camera includes a screen suitable for displaying a high resolution version of a stored image from a list of stored images when a location within the list is selected.

Techniques for recovering optical spectral features include receiving a detected time series that represents a temporally varying intensity of an optical signal. The optical signal is formed in response to an interaction between a target optical spectrum and a chirped optical field. The chirped optical field is an optical field that has a monochromatic frequency that varies in time. The target optical spectrum is an optical frequency dependent optical property of a material or device. A phase correction factor is determined based only on one or more properties of the chirped optical field. The detected time series is corrected based on the phase correction factor to produce an output time series that reproduces in time a shape of the target spectrum in frequency. These techniques allow for fast measurement of spectral features and eliminate the need for prior knowledge of the target optical spectrum to adjust the chirp rate.

Embodiments include systems and methods for detecting and correcting phased clock error (PCE) in phased clock circuits (e.g., in context of serializer / deserializer (SERDES) transmission (TX) clock circuits). For example, phased input clock signals can be converted into unit interval (UI) clocks, which can be combined to form an output clock signal. PCE in the output clock signal can be detected by digitally sampling the UI clocks to characterize their respective clock pulse widths, and comparing the respective clock pulse widths (i.e., PCE in the output clock signal can result from pulse width differences in UI clocks). Delay can be applied to one or more UI clock generation paths to shift UI clock pulse transitions, thereby adjusting output clock pulse widths to correct for the detected PCE. Approaches described herein can achieve PCE detection over a wide error range and can achieve error correction with small resolution.
