An eye controllable screen pointer system is provided that combines eye gaze tracking and screen tracking from the point of view of the user. Screen tracking is performed by a screen tracking camera, attached to a helmet the user is wearing. The screen tracking camera is aided by either light emitted from screen beacon located near the screen, or by a light pattern emitted from the screen itself as a screen beacon signal. The screen tracking means provides a screen tracking signal. Eye gaze tracking is performed as is known in the art, or according to a novel way described herein. An eye gaze tracking means is attached to the helmet, and provides an eye tracking signal. The information carried in the screen tracking signal and in the eye tracking signal are combined in a calculation by a processing means residing in a processor to produce a point of computed gaze on the screen. In an alternate embodiment of the invention, the input device of both the eye gaze tracking means and the screen tracking camera are combined into a single video camera, thus resulting in a simplified apparatus. Optionally, the system further projects a mark at the point of computed gaze.

Methods and apparatus are provided for portable medical devices such as defibrillators having different charging and operating voltages. The apparatus comprises a connection for receiving DC input voltage VIN, an energy storage device (e. g. , a capacitor), a battery having at least two cells therein coupled to the connection and the capacitor, and switches to selectively reconfigure the battery cells so as to: (i) charge from VIN, and (ii) discharge to the capacitor at VOUT>VIN. The method comprises charging the battery from VIN while its cells are arranged substantially in parallel, then reconfiguring the switches to arrange some of the charged cells substantially in series to give VOUT>VIN, and then charging the capacitor therefrom. The cells are thereafter reconfigured back to the parallel arrangement ready to be recharged from VIN. Isolation switches are conveniently provided to isolate the battery from VIN while charging the capacitor.

A system is provided for delivering a defibrillation pulse to a patient and a corresponding method of storing such a system is provided in accordance with the present invention. The system includes a defibrillator (e. g. , an AED) that is configured to deliver the defibrillation pulse to the patient and a cell that is configured to convert light into electrical power for the defibrillator. The method includes storing an defibrillator of the system for future use and arranging a light receiving system to receive light such that the light receiving system converts light into electrical power for the defibrillator.

The invention provides an elevator cab equipped with an emergency medical device, such as an automated external defibrillator (AED). The elevator cab equipped with the emergency medical device may be controlled in order to deliver the emergency medical device to a floor of a building on which an emergency medical situation occurred. In response to emergency medical input identifying the emergency medical situation, an elevator control unit overrides regular operation of the elevator cab in response to receiving emergency medical input, and directs the elevator cab to a floor on which an emergency medical situation occurs. For example, the elevator control unit may cancel active floor calls made by passengers within the elevator cab or individuals on one or more floors of the building and direct the elevator cab to the floor of the emergency situation.

Wall reflectors work in conjunction with devices that emit wall laser beams, for assisting the attachment on a wall of items such as pictures. The wall reflectors are constructed to be attached on the wall, and to provide surfaces for reflecting the laser light beam into rays. Multiple wall reflectors can optionally also provide a whole pattern on the wall, such as a grid.

Methods and apparatus are provided for minimizing the inherent time delays within external defibrillators. The methods and apparatuses utilize timing schemes for initiation and completion of charging of an energy storage device of an external defibrillator, measuring one or physical parameters of the patient and conducting a physiology analysis of the patient. The initiation and completion of one or more of these activities are arranged so that the energy storage device is charged to a desired level and available for a defibrillation shock to the patient with minimal delay after activation of the external defibrillator.

Systems, software, devices, and methods are described for an RFID reader system to communicate with RFID tags. RF energy encountered in conjunction with using a selected channel is detected. The RF energy can be a signal from an RFID tag. The detected signal is used to adjust a waveform shaping parameter. RF waves can be transmitted from the reader to the RFID tags and RF waves can be backscattered from the RFID tags. At least some of the RF waves transmitted to or backscattered from the RFID tags have a waveform with a shape according to the adjusted waveform shaping parameter.
