  • Patent number: 12685510
    Abstract: A photoacoustic (PA) sensor employs a linear deployment of an illumination source and a corresponding ultrasonic receiver for defining an imaging plane for rendering a PA image of a surgical or diagnostic region. A pair of illumination sources emanates from cladding removal of respective optical fibers, and irradiates in alignment with a side firing ultrasonic (US) array for receiving the induced PA signals. The US array extends longitudinally and parallel to the illumination sources, and an overlap of the respective irradiation regions extends from the illumination sources lies within a sensing region of the US array for defining an imaging plane captured by the US sensor for rendering on a visual device, often in conjunction with an ablation antenna or diagnostic probe for providing concurrent imaging during a surgical procedure.

  • Patent number: 12564501
    Abstract: A prosthetic device and approach for amputee remediation addresses partial or complete replacement of digits, and leverages the use of the remaining functional digits for directing operation of the prosthetic digits. A complete prosthetic digit replaces an amputated digit from actuated movement driven by an adjacent functional digit. A partial amputation leverages residual movement from the remaining digit portion as input to an actuator for amplifying the intent of the input through a motorized actuator to impart movement to the prosthetic digit. A wrist harness supports the apparatus of partial and complete prosthetic digits as a single appliance. A variable compression feature augments tension on the wrist harness to tightly engage the prosthetic appliance to the wrist to offset a gripping load on the prosthetic digits.

  • Patent number: 12559690
    Abstract: A waste stream of organic matter such as sewage, plant and plastic matter is received for recycling and treated with high temperature and pressure to generate useful organic products such as bio-oil and gas. Byproducts such as char and an aqueous phase including water can be selectively recycled or beingly discarded. An oxidant added to a reactor containing waste from the waste stream facilitates an autothermal reaction under the temperature and pressure applied to the reactor, boosting the temperature slightly from the reactions therein. The reactor generates useful hydrocarbons such as bio-oil resulting from disruption of organic bonds. A combination of oxidation and radical initiation results from the oxidant, and provides an increased yield of bio-oil while decreasing char when compared to temperature and pressure alone. A stoichiometric quantity of the oxidant limits complete conversion of carbon into carbon dioxide by limiting available oxygen and therefore favoring hydrocarbon formation.

  • Patent number: 12528709
    Abstract: Bauxite residue recovery includes mixing a solution of hydrochloric acid (HCL) according to a predetermined concentration, and adding the HCL solution to a quantity of raw red mud recovered from industrial operations as waste material. The highly alkaline property of the bauxite residue, commonly known as red mud is at least partially neutralized from the HCL, and makes the resulting washed red mud more amenable to subsequent uses in various applications in fields such as construction, wastewater treatment, and metal recovery processes. The process recovers washed red mud from the red mud and HCL solution by filtering the raw red mud and HCL solution for generating a stream of leach liquor from the filtrate and the recovered washed red mud from the residue. The neutralized red mud is further treated to extract metals such as calcium, iron, aluminum, silicon, and titanium.
