Abstract: An information processing device includes a display, a communication interface configured to receive signals from a tap device, one or more processors, and one or memories storing instructions. Upon execution by the one or more processors, the instructions cause the one or more processors to: display a plurality of icons on the display in a predetermined pattern as a graphical user interface; in response to a selection signal received from the tap device, select one of the plurality of displayed icons; in response to an activation signal received from the tap device, activate a function corresponding to the selected icon; and in response to a shift signal received from the tap device, shift the plurality of icons to different positions in the predetermined pattern.

Abstract: A personal exhaled air removal (PEAR) system for removing/evacuating exhaled air from a vicinity of a patient is designed to remove the exhaled air during an exhalation cycle of a patient. The system is synchronized with a patient's breathing cycle for activating suction of exhaled air via at least one suction inlet, and the suction inlet is adjacent to the patient, possibly attached to the patient via an interface.

Abstract: Apparatus for diastole trimming including a controller for producing a diastole ending signal, and one or more leads connected to the controller, for carrying the signal to lead connections to a heart, characterized by the controller detecting when a left ventricle (LV) of the heart is mostly full, and producing the diastole ending signal such that the diastole duration is trimmed. Apparatus for diastole trimming including a controller for producing a diastole ending signal, and a connection to a pacemaker, characterized by the controller having decision rules for indicating to the pacemaker when to fire and end the diastole. A method of programming a pacemaker characterized by increasing cardiac output by trimming duration of diastole. A method for increasing cardiac output including producing a signal to trim diastole duration, thereby increasing heart rate (HR) and increasing a product of stroke volume (SV) times HR. Related apparatus and methods are also described.
