Abstract: A portable, interactive medical electronic device exemplified by a defibrillator. The device obtains information about a patient's condition, such as ECG and transthoracic impedance data, directly from the patient, and information pertinent to the treatment of the patient indirectly through an operator of the device, and produces a medically appropriate action such as a defibrillation shock in response. Indirect information is obtained through information processing means that includes means for prompting the operator of the device and means for receiving the operator's responses thereto. Prompts may include both questions and instructions, and in one embodiment the information processing means obtains the assent of the operator before causing the defibrillation shock. Indirect information may include information as to whether the patient is conscious, and as to whether or not cardiopulmonary resuscitation has been performed.

Abstract: A combination floating breakwater and wave energy collecting system in which a pair of joint floating spread wings are provided between which a vessel can be moored. The spread angle of the wings is adjustable and the wings can be jointly swung about their juncture so as to extend from the juncture generally in the direction of wave and wind travel so that the vee-shaped area between the wings is on the lee side. The wings have rows of improved wave energy collecting cells used to drive air turbines coupled to electric generators without intermediate compressed air storage and this energy conversion assists in dampening the wave action in the moorage zone between the wings.
