A wearable cardiac defibrillator (WCD) system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments, the WCD system includes a speaker system, a memory and a proximity detector. Prompts have been stored in the memory. In case of an emergency, upon inferring that no bystander is nearby, the speaker system may transmit a sound at a higher intensity than otherwise, hoping to attract attention.

[ABSTRACT]

An automated external defibrillator (1) includes: a display (100) that presents at least one of time information regarding a time length until an electric shock is delivered, an illustration regarding reception of the electric shock, and a warning text regarding the reception of the electric shock, and a display controller (103A) that controls the display (100), wherein the display controller (103A) changes a color presented on the display (100) in accordance with the time length until the electric shock is delivered.

In one embodiment, a defibrillation assembly energizable through case opening is provided. The defibrillation assembly includes an electromechanical component; an energy storage element that supplies power to the electromechanical component; circuitry configured to generate a defibrillation waveform, wherein the circuitry is isolated from the energy storage element by the electromechanical component; a housing within which the circuitry is located; and a case within which at least a portion of the housing is located, wherein an opening of the case causes the power to flow to the circuitry through the electro-mechanical component.

A defibrillation assembly energizable through pad removal is provided. The defibrillation assembly includes an electromechanical component; an energy storage element that supplies power to the electromechanical component; circuitry configured to generate a defibrillation waveform, wherein the circuitry is isolated from the energy storage element by the electromechanical component; and electrode pads through which the defibrillation waveform is delivered to a patient, wherein a removal of at least one of the electrode pads from an initial position to a further position causes the power to flow to the circuitry through the electro-mechanical component.

A wearable cardiac defibrillator (WCD) system may include a support structure that a patient can wear, an energy storage module that can store an electrical charge, and a discharge circuit that can discharge the electrical charge through the patient so as to shock him or her, while the patient is wearing the support structure. Embodiments may actively take into account bystanders, both to protect them from an inadvertent shock, and also to enlist their help. In some embodiments the WCD system includes a microphone. The WCD system might be ready to deliver a shock, but may first wait before doing so until it hears from a bystander a preset ready word, such as: CLEAR.
