  • Patent number: 11950848
    Abstract: An example system for microvascular assessment of a patient can include: a fundus imaging device including: a camera configured to capture one or more images of an eye of the patient; and at least one light source; and a microvascular assessment computing device including: a processor; and memory encoding instructions which, when executed by the processor, cause the system to: activate the light source to direct light at a fundus of the eye of the patient; capture, with the camera, one or more images of the fundus of the patient, the fundus comprising a plurality of blood vessels; and analyze with the microvascular assessment computing device, the one or more images to determine a microvasculature health index for the patient.

  • Patent number: 9960715
    Abstract: Provided is a light activated piezoelectric converter comprising a cantilever vane coupled to a foundation. The vane comprises a first surface and a second surface. The first and second surfaces are generally co-planer and adjacent to a common boundary and have differing emissivities. A piezoelectric material is additionally coupled to the vane, arranged such that a deflection of the free end of the vane generates stress acting on the piezoelectric material. When the piezoelectric converter is illuminated with a radiant flux, the differing emissivities of the first and second surfaces produce a temperature gradient across the vane and a thermal creep force across the planar surface generates a deflection of the vane, and a subsequent voltage induced by the stress on the piezoelectric material generates a voltage between a first electrode and second electrode in electrical contact with the piezoelectric material.

  • Patent number: 9822786
    Abstract: Provided is a light activated rotor comprising typically a plurality of vanes affixed to a hub rotatable around the longitudinal axis of an axle. Each vane comprises a planar surface oriented generally perpendicular to the longitudinal axis of the axle with each vane separated into a first surface and a second surface. The first and second surface are adjacent and share a common boundary generally perpendicular to the longitudinal axis of the axle. Additionally, the first and second surfaces have differing emissivities. When the light activated rotor is illuminated with a radiant flux, the differing emissivities of the first and second surfaces produce a temperature gradient across the vane and generally perpendicular to the longitudinal axis, and a thermal creep force across the planar surface of the vane generates a revolution of the vane and the affixed hub around the longitudinal axis of the axle.

  • Patent number: 9705383
    Abstract: Provided is a light activated generator comprising typically a plurality of vanes affixed to a hub rotatable around the longitudinal axis of an axle. Each vane comprises a conductor and comprises a planar surface oriented generally perpendicular to the longitudinal axis of the axle with each vane separated into a first surface and a second surface. The first and second surfaces are generally co-planer and perpendicular to the longitudinal axis of the axle. Additionally, the first and second surfaces have differing emissivities. When the light activated generator is illuminated with a radiant flux, the differing emissivities of the first and second surfaces produce a temperature gradient across the vane, and a thermal creep force across the planar surface generates a revolution of the vane around the longitudinal axis of the axle to motivate the conductor through a magnetic field, generating a voltage across the conductor.

  • Patent number: 8624497
    Abstract: A THz reverse micromagnetron includes a MEMS-based reverse magnetron configuration in which the anode is located at the center of the magnetron surrounded by a cathode ring. Electrons move radially inward in the combined electric and magnetic cross-fields and can reach orbiting angular frequencies in the THz region, even with a magnetic field of the order of 1 T or less. The THz reverse micromagnetron is portable, operates at room temperature, and can be bright.

  • Patent number: 8221976
    Abstract: The present invention relates to a method of detecting the presence or absence of herpes simplex virus (HSV) in a sample based on amplifying a portion of the Glycoprotein G(US4) gene of HSV and detecting the presence of the amplified nucleic acid using primers and detector primers as described herewith. The method of the invention further identifies the type of HSV, either HSV-1 or HSV-2, in a sample. Also encompassed by the invention is a kit comprising the primers and detector primers which may be used with the amplification method described herewith.

  • Patent number: 8166094
    Abstract: A process for quiescing a master and a plurality of subordinate computer systems in a cluster. An original or a pending state may be entered that is a quiesce or an online state. The master instructs the subordinates the quiesce or online state be made the pending state. The subordinates prepare to change accordingly, determine whether successful, and vote to commit or abort. Based on whether all voted to commit, the master instructs the subordinates to either commit or abort. If to commit and the pending state is the quiesce state, an operation is performed in the subordinates. If to commit and the pending state is the online state, the subordinates prepare to resume the original state. The subordinates change from the original to the pending state. Otherwise, if to abort, the subordinates prepare to remain in the original state and reset the pending to the original state.

  • Patent number: 8126442
    Abstract: A two component highly portable and lightweight system for extending the transmission capabilities of Land Mobile Radio systems into areas lacking coverage due to structures, depth below the earth's surface, or varying terrain or other dead zones lacking coverage. The system utilizes the Radio over IP protocol to transfer two-way audio from one radio to another radio for re-broadcast inside a dead zone over a 900 MHz Ethernet-based point-to-point wireless link. The novel system includes RF to TCP/IP conversion and digital data transmission followed by a TCP/IP conversion to RF radio link and provides components and a method for bridging RF radio into dead zones.
