Patent number: 11433959Abstract: A four-wheeled articulated steering vehicle for terrain exploration. The four-wheeled articulated steering vehicle has a pair of robotic tethered two-wheel vehicles that dock, lock, and drive long distances as the four-wheeled, articulated steering vehicle. Two actuated docking mechanisms attached on opposite ends of a central module of the four-wheeled vehicle enable “sit/stand” functionality. The “sit” configuration is achieved by aligning each dock mechanism parallel or nearly parallel to the surface, allowing two-wheel vehicle to detach and explore while the other remains docked and serves as a backup. While ‘sitting’, the central module rests on the ground and is outfitted with shovel-style wedges for passive anchoring. In order to “stand”, the exploring two-wheel vehicle reattaches, locks, and both dock mechanisms are rotated until each two-wheel vehicle's caster arm is upright and the central module is lifted off the ground.Type: GrantFiled: August 14, 2020Date of Patent: September 6, 2022Assignee: CALIFORNIA INSTITUTE OF TECHNOLOGYInventors: Patrick Mcgarey, Issa A Nesnas

Patent number: 11432802Abstract: A system and method for controlling the delivery of ultrasound energy to a subject is provided. In particular, such a system and method are capable of safely disrupting the blood-brain barrier. Ultrasound energy is delivered to produce cavitation of an ultrasound contrast agent at a selected pressure value. An acoustic signal is acquired following cavitation, from which a signal spectrum is produced. The signal spectrum is analyzed for the presence of harmonics, such as subharmonics or ultraharmonics. When subharmonics or ultraharmonics are present, the pressure value is decreased for subsequent sonications. If a previous sonication resulted in no subharmonics or ultraharmonics being generated, then the pressure value may be increased. In this manner, the blood-brain barrier can be advantageously disrupted while mitigating potentially injurious effects of the sonication.Type: GrantFiled: July 6, 2020Date of Patent: September 6, 2022Assignee: SUNNYBROOK RESEARCH INSTITUTEInventors: Meaghan Anne O'Reilly, Kullervo Henrik Hynynen
