Abstract:

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.

Allen Tanner - Sandy UT, US

International Classification:

G02B 27/10

US Classification:

359621, 359627

Abstract:

An optical assembly for reducing the etendue of a diode laser light source having a plurality of laser light emitters. The optical assembly comprises a first optical device for collimating beams of light emitted from the emitters of the diode laser. A second optical device spatially shifts a portion of the collimated light beams emitted from the diode laser to thereby reduce gaps or dark space between the beams. A third optical device focuses all of the light beams onto a surface, such as a surface of a light modulation surface.

US Classification:

353 37, 359290, 362553

Abstract:

An illumination system for transforming at least one laser light beam having a non-uniform distribution in a first axis and a second axis to a beam having a substantially uniform distribution in the first axis while preserving the non-uniform distribution in the second axis. The transformed beam may be imaged as a line image onto a one-dimensional light modulation device. The illumination system may comprise a light tunnel having two sides that interact with the at least one laser light beam in the first axis and two sides that do not interact with the light in the second axis.

Appl. No.:

13/277122

Inventors:

Chris Cindrich - Draper UT, US
Robert D. Christensen - Layton UT, US

International Classification:

B65D 49/00

US Classification:

215 49

Abstract:

An apparatus includes and ampoule and a protective sleeve. The ampoule includes a body portion and an openable end portion. The body portion defines an internal cavity for containment of a substance. The openable end portion is configured to be opened by removal of a distal section, which upon removal creates an opening into the internal cavity of the body portion for liberation of the substance from the internal cavity. The protective sleeve is disposed over at least a portion of the openable end portion. The protective sleeve provides a contamination barrier to prevent contamination of an outer surface of the openable end portion covered by the protective sleeve.

Abstract:

A network node that includes at least one processor, at least one memory, and at least one network interface. The network node is configured to be within a plurality of network nodes communicatively coupled in a peer-to-peer network of network nodes implementing a distributed ledger. The network node is communicatively coupled to at least one remotely located computing device through the at least one network interface. The at least one processor is configured to deploy a second smart contract at a second address on the distributed ledger; set an address field in the first smart contract to reference the second address; subtract a particular number of tokens from a first respective value corresponding to a first respective address in the first table of balances; and add the particular number of tokens to a second respective value corresponding to the second address in the first table of balances.

Abstract:

A network node includes at least one processor, at least one memory, and at least one network interface. The network node is configured to be within a plurality of network nodes communicatively coupled in a peer-to-peer network of network nodes implementing a distributed ledger. The network node is configured to be communicatively coupled to at least one remotely located computing device through the at least one network interface. The at least one processor is configured to determine a split ratio for a new split of security tokens held in at least one address of the distributed ledger. The at least one processor is also configured to store an indication of the split ratio without updating token balances for all of the at least one address in a list of addresses holding at least one of the security tokens.

A network node that includes at least one processor, at least one memory, and at least one network interface. The network node is configured to be within a plurality of network nodes communicatively coupled in a peer-to-peer network of network nodes implementing a distributed ledger. The network node is communicatively coupled to at least one remotely located computing device through the at least one network interface. The at least one processor is configured to deploy a child smart contract, which is a subsequent version of a parent smart contract, on the distributed ledger. The at least one processor is also configured to set an upgraded address field in the parent smart contract to point to an address of the child smart contract. The parent smart contract remains deployed after the child smart contract is deployed.
