Abstract: A system and method provides a status indicator to a battery pack of a medical device. The battery pack includes a power supply capable of being connected to the medical device. The battery pack also includes an indicator to automatically indicate a status of at least a portion of at least one of the battery pack and the medical device. For example, the indicator can indicate a status of the power supply.

Abstract: An external defibrillator enclosure for use in conjunction with a defibrillator accessory, such as an electrode pad assembly, includes a front panel and a rear panel which are mated together and secured by a coupling means. The enclosure also includes a plate secured by a coupling means to the second panel. The plate and second panel are positioned relative to each other to form a slot that is sized to receive a portion of the electrode assembly. The enclosure also includes a connector port that allows for the electrode pad assembly to be pre-connected to the electronics within the enclosure. The electrode pad assembly includes a cable and a connector at the end of the cable, and the exterior face of enclosure rear panel includes a groove that is sized to receive and retain the cable. The groove holds the cable in place against the surface of the enclosure while the cable is connected to the connector port.

Abstract: An AED includes defibrillation circuitry housed within an enclosure, a first processor programmed to periodically test the operability of the defibrillation circuitry and a second processor in communication with the first processor. The AED further includes a visual indicator, such as a red/green LED, positioned at the exterior of the enclosure that is operatively connected to the second processor. The second processor is programmed to control the visual indicator in response to the periodic test results provided to it by the first processor.

Abstract: A battery system for a medical device includes a first power supply and a second power supply. The first power supply is capable of being connected to the medical device to supply power to the medical device during a first operating mode of the medical device. The second power supply supplies power to at least one of a portion of the medical device and the battery system during an alternate mode, exclusive of a state the first power supply.

Abstract: A hoop type toy is provided having a sound generating system for generating a tone, a steady simple beat, a rhythmic beat, or a tune. In certain embodiments, sound generation only occurs when the hoop is in motion. In other embodiments, the rate, pitch, speed, and/or loudness of the tone, beat or tune varies with the rate of rotation of the hoop. In the preferred embodiments, the sound generating system includes a speaker and a circuit board having an IC chip and integral motion detector. In this way, ruggedness, low cost, and small size are achieved.
