Abstract: In an embodiment, a method includes obtaining radiation emitted from a radiation source. The method includes modulating the radiation with a time-varying modulation to generate a time-varying illumination pattern with a known modulation. The illumination pattern includes a time-varying intensity for each of a plurality of spatial locations. The method includes illuminating a target volume with the illumination pattern. The method includes collecting a signal generated by one or more objects within the target volume in response to illumination by the illumination pattern. The method includes estimating a location of each of the one or more objects based on the collected signal and the known modulation.

Abstract: In some implementations, tokens that are representative of sensitive data may be used in place of the sensitive data to maintain the security of the sensitive data. For example, data may be separated into sensitive data and nonsensitive data, and at least the sensitive data is securely delivered to a data storage service. The data storage service generates a token that is representative of the sensitive data and stores the sensitive data as secure data. The data storage service may deliver the token to an entity that also receives the nonsensitive data, and the entity may use the token in place of the sensitive data. In some implementations, different tokens are generated each time the same piece of sensitive data is submitted for storage as secure data. Further, in some implementations, An expiration time may be assigned to sensitive data, and expired data and associated tokens may be deleted.

Abstract: In an example embodiment, a method includes emitting broad bandwidth radiation with high spatial coherence. The method includes applying a time-varying modulation to the broad bandwidth radiation. The method includes identifying optical interactions caused by the time-varying modulation of the broad bandwidth radiation.

The method includes extracting one or more respective spectral signatures associated with each respective signal of the one or more signals. The method includes determining a respective characteristic of an optically interacting material that corresponds to a respective spectral signature of the extracted spectral signatures. The method includes identifying one or more optically interacting materials by classifying one or more of the characteristics.

Abstract: A security service enables service providers to register available services. Prospective service consumers may register with the security service to access a particular registered service, and may specify conditions for access that are subject to approval by the corresponding service provider. Based on the registrations of the service provider and the service consumer, the security service can define access policies that may be enforced to control the conditions under which a service consumer accesses or utilizes the particular service. Additionally, changes to the access policies may be propagated to running services in near real time. Some implementations enable masking of information provided to particular service consumers based on determined needs of each service consumer for access to particular information. In some instances, the service providers may provide log information to the security service, which may be monitored to identify anomalies, security breaches or the like.

Abstract: Systems and methods are disclosed to determine the axial and/or lateral location of a particle using light modulated with temporal and/or spatial modulation pattern. The system, for example, may include a modulator configured to temporally modulate an intensity pattern of a line of light uniquely at each point along a lateral length of the line of light and produce an undiffracted modulated line of light, a first first-order diffracted line of light, and a second first-order diffracted line of light; and one or more optical elements configured to direct the undiffracted line of light and one of the first first-order diffracted line of light and the second first-order diffracted line of light toward at least one particle disposed at or near a sample region. The system may include a processor configured to determine an axial and/or a lateral position of the particle disposed at or near the sample region.
