A network node in a peer-to-peer network of nodes includes at least one processor, at least one memory, and at least one network interface. The at least one processor is configured to receive a request to transfer a security token and execute a plurality of compliance rules associated with the security token. At least one of the compliance rules is implemented using at least one smart contract. The at least one smart contract references a global registry. The at least one processor is also configured to transfer the security token based on the execution of the compliance rules. The global registry includes personally identifiable information (PII) hash(es) for each of at least one investor associated with the transfer of the security token. The hashes are committed to the distributed ledger and updated when PII of a respective one of the at least one investor changes.

Systems and methods described herein generally relate to storing and verifying data. In some embodiments, reference levels are generated according to time intervals, where the first reference level comprises a predetermined number of the time intervals, and where each of the time intervals of the remaining reference levels is comprised of a predetermined number of the time intervals of a previous reference level. Hashes of data can be created at the first reference level by performing a hashing function on the data in a time-sequenced manner. First reference level time interval hashes may be generated by performing the hashing function on the hashes of the data at each of the time intervals of the first reference level. Hashes for remaining reference level time intervals can be generated by performing the hashing function on the hashes of each of the time intervals of the previous reference level.

A display system able to reduce interpixel intensity gaps caused by the use of pulsed laser sources having relatively short optimum pulse duration. The interpixel intensity gaps are reduced by temporally offsetting multiple laser pulses for a display pixel during a corresponding pixel-scan period. The temporally offset pulses for the display pixel are then scanned to different locations on a viewing surface such that the display pixel has an improved intensity distribution. Additional reduction in the interpixel gaps may be accomplished by de-focusing the temporally offset pulses in a scan direction, increasing the duty cycle of the source lasers, and shifting the location of alternating frames on the viewing surface.

Projection method for reducing interpixel gaps on a viewing surface

A projection system that includes a singe light modulation device and a plurality of light sources of different wavelengths. Each wavelength of light is incident on the light modulation device at a spatially distinct location and a temporally distinct time. The use of a scanning mirror allows the projection system to sequentially form, in full-color, each of the columns or rows of an image. The projection system is characterized by the reduction of color separation or the rainbow effect due to the rendering of each column or row in full color.

A system and method for generating a high-resolution image using a scanned-column projector is disclosed. The method includes the operation of generating a time-varying line image. A further operation includes collimating the time-varying line image in at least one plane. An additional operation involves scanning the collimated time-varying line image using a scan mirror. A further operation includes projecting the scanned collimated time-varying line image onto a surface. The scanned collimated time-varying line image is projected with at least one imaging element.

A system and method is disclosed for reducing visibility of image artifacts caused by diffractive elements in a laser projector having a structured diffractive device. At least two diffracted orders of light can be selected from light emitted from the structured diffractive device using a spatial light filter. The polarization of at least one of the selected diffracted orders can be changed with respect to another selected diffracted order. The selected diffracted order can be recombined to form an image having reduced visible image artifacts.

A wide angle display system includes a linear array projector, a curved display surface, and an n-sides scanning mirror. The projector is configured to project an image along an optical axis to the scanning mirror. The scanning mirror continuously rotates about a rotational axis at a speed 1/n the refresh rate, so as to reflect and scan the image onto the display surface.

Wide angle scanner for panoramic display

The invention provides a system and method for reducing laser speckle and interference patterns in a laser projector display when using a laser projector having a spatial light modulator (SLM) with a defined pixel rate. The method can include the operation of polarizing a laser output of a continuous wave laser such that the laser output is s-polarized with respect to a beam combiner. The s-polarized laser output can be divided into a first laser beam and a second laser beam. A phase of the second laser beam can be modulated with an amplitude sufficient to create a phase delay of approximately half a wavelength of the laser output and at a frequency at least twice that of the SLM's pixel rate.
