Publication number: 20210338931Abstract: Embodiments disclosed herein relate to detection systems for an infusion pump. An occlusion detector for an infusion pump includes a membrane that deforms in response to fluid pressure in a fluid flow path branching off of the main fluid flow path of the infusion pump. The membrane deforms in response to fluid pressure, applying an axial pressure to a piston, which in turn triggers a force sensor. A controller of the infusion pump triggers an alarm or alerts a user when a threshold is reached. A bubble detector for the infusion pump includes a light emitter and reflective surface. Light shines through the fluid flow path, refracting differently if there is air present in the flow path. A light sensor detects the light and conveys an output signal to the controller. If detected air surpasses a threshold, the controller sounds an alarm or otherwise alerts the user.Type: ApplicationFiled: September 24, 2019Publication date: November 4, 2021Applicant: Takeda Pharmaceutical Company LimitedInventors: Andrew Scott Argersinger, Brent Whitfield Byers, Jason Paul Stubbs

Patent number: 9153924Abstract: An electrical control system for a rotatable wheel cover assembly is presented, the system including a controller assembly comprising processors for controlling the relative motion of a wheel cover rotatably mounted to a wheel frame of a vehicle. The controller assembly outputs a first signal to motor drivers, which are mounted within the vehicle separated from the wheel cover, the motor drivers passing a first drive frequency to motor leads for open loop control of the speed of the motors that drive the wheel cover. The electrical control system provides power from an inboard side of the wheel frame to an outboard side via a slip ring assembly having connector assemblies passing through the wheel frame for controlling motion of the wheel cover. The wheel cover is mounted to a shaft of the motor, wherein the motor is mounted coaxially with the wheel frame.Type: GrantFiled: December 6, 2012Date of Patent: October 6, 2015Assignee: ALTAMOTIVE, LLCInventors: Brent Whitfield Byers, Nicholas Conway
