Abstract: Described herein are solid state sensors for measuring various physical parameters. The solid state sensors may be used in systems, devices, and methods for controlling blood flow or for measuring (e.g., monitoring) blood pressure. In some instances, the method may include obtaining a first count number indicating a number of oscillations at a first ring oscillator circuit during a sample period. The first ring oscillator circuit may be associated with a sensor and oscillates at a first oscillation rate. The first oscillation rate may be based on a first set of physical parameters and a second physical parameter. The method may further include obtaining a second count number indicating a number of oscillations at a second ring oscillator circuit during the sample period. The second ring oscillator circuit may be associated with the sensor and oscillates at a second oscillation rate. The second oscillation rate may be based on the first of physical parameters but not the second physical parameter.

Abstract: Devices, systems, and methods for minimization of backlash in a syringe pump are described herein. Syringe pumps may comprise a syringe including a cylindrical body and a plunger, and a controller. The plunger may comprise a linear gear that may operably couple with a circular gear in the controller. The controller may be configured to bias the circular gear in a biasing rotational direction, thereby positioning the plunger to move towards a biasing translational direction. The methods may comprise determining a backlash compensation amount, determining a fluid transfer movement amount, moving at least one component of the syringe pump the backlash compensation amount and the fluid transfer movement amount in a first direction, and moving the at least one component of the syringe pump a biasing movement amount in a second direction opposite the first direction to re-engage the first gear and the second gear to minimize backlash.

Abstract: Methods for performing endovascular procedures are described herein. The methods may comprise advancing an expandable member of a blood flow control device to a target location in a blood vessel of a patient, and rotating a circular gear positioned at least partially within a housing of a controller via the controller communicably coupled to the blood flow control device. Rotating the circular gear may translate a linear gear of a syringe pump fluidly coupled to the expandable member thereby adjusting a volume of the expandable member. Various blood flow control devices, control systems, and fluid delivery systems are also described herein. The fluid delivery systems may include a pump configured for manual or automated delivery of fluids, or configured to switch between automated and manual modes of delivery. The pump may be a syringe pump that utilizes a rack and pinion system, a motor, and a sensor to track the position and/or movement of a component of the syringe pump during fluid transfer.

Abstract: Disclosed are systems and methods for reducing blood pressure variability in a patient. The system includes an endovascular catheter having an expandable element and one or more blood pressure sensors, and a computer/processing unit configured to receive blood pressure measurements and determine a blood pressure variability metric. Upon determining that the blood pressure variability metric exceeds a given blood pressure variability threshold or falls outside a predefined range, the computer/processing unit directs a catheter controller to adjust the size of the expandable element of the catheter, thereby modulating blood pressure and reducing blood pressure variability.

Abstract: Technologies for projecting a noncontinuous image onto at least a portion of a projection region using a projector of a projection device. The projection device is configured to determine one or more cut-out areas of the projection region. Each cut-out area defines an area within the projection region on which a corresponding portion of the image is not to be projected by the projector of the projection device. The projection device is further configured to update the projection region based on the cut-out area(s) and project, via the projector, the image onto the updated projection region, wherein no portion of the image is projected on cut-out area(s). Other embodiments are described and claimed.
