Abstract: Infusion systems, infusion devices, and related operating methods are provided. An exemplary infusion device includes a motor operable to deliver fluid to a body of a user, a first control module, and a second control module. The first control module and the second control module are coupled to one another. The first control module enables input power for the motor in accordance with a handshaking sequence of communications between the first control module and the second control module and provides a dosage command to the second control module, with the second control module operating the motor using the input power based on the dosage command in accordance with the handshaking sequence of communications.

Abstract: A personal medical device and method of use with restricted mode challenge having a personal medical device including: a memory operable to store programming code; a processor operably connected to the memory; a user input having input buttons to receive input from the user; and a user display to display output to the user. The processor is operable to: detect a user request for entry to the restricted mode; display a user input image on the user display, the user input image including display buttons corresponding to the input buttons; highlight one of the display buttons; detect actuation of one of the input buttons on the user input; and deny entry to the restricted mode when the one of the input buttons does not correspond to the highlighted display button.

Abstract: A toy includes a first pivot joint, a second pivot joint, a first shaft held by the first pivot joint such that the first shaft can pivot in any direction, a second shaft held in the second pivot joint such that the second shaft can pivot in any direction, and a coupling between the first shaft and the second shaft configured such that motion applied to one shaft produces a mirrored motion in the other shaft. The toy may be configured to have the appearance of a dinosaur such as triceratops.

Abstract: A device for striking a ball, such as a soft foam rubber ball, includes a ball striking element including a clear transparent shell portion which is formed in a configuration similar to a device such as a golf club or a baseball bat and a colored liquid in an inner cavity in the shell portion. The colored liquid only partially fills the inner cavity in the shell portion so that it not only acts to transfer weight in the device during a ball striking exercise but to also provide a unique splashing visual effect.

Abstract: A toy gun includes a ball holding member and a piston and cylinder assembly for producing blasts of compressed air in order to launch soft foam balls from the ball holding member. The gun further includes a water supply assembly for supplying water to the piston and cylinder assembly so that a quantity of dispersed water is expelled from the gun when a ball is launched therefrom.
