Abstract: A percussive therapy device that includes a housing, an electrical source, a motor positioned in the housing, a switch for activating the motor, a push rod assembly operatively connected to the motor and configured to provide reciprocating motion in response to activation of the motor, and a massage attachment secured to a distal end of the push rod assembly. The reciprocating motion of the push rod assembly has a user-adjustable amplitude.

Abstract: A portable external device for a mechanical circulation support system includes first and second power sources, e.g. batteries and control electronics for redundant uninterrupted operation of an implantable blood pump. The control and power source module may be configured for variable form factors to accommodate a variety of wearable configurations for patient convenience and comfort.

Abstract: A pulse rate sensor that includes an accelerometer for measuring periodic motion and a piezo sensor for detecting erratic motion is capable of more accurately determining pulse rate by accounting for these types of motion. The pulse rate sensor in accordance with the present invention diminishes pulse rate signal degradation due to erratic motion through a combination of algorithms that control signal boosting, waveform refinement and signal noise suppression.

Abstract: A network communication and messaging protocol for use in a medical perfusion system, provides the rules which govern how, among other things, information and data is conveyed between the various devices which are connect to the network. The rules define the different types of messages that are used in conveying information and data, as well as the formatting for each of those message types. The various messages provide the ability to configure the perfusion system devices, establish links between the perfusion system devices, and convey various types of information and data, even when the main network controller is unavailable.

Abstract: Continuous volume detection for a reservoir in a fluid circuit of a medical system is described. Volume detection is based on a pressure measurement that is manipulated via application of fluid mechanics. Next-generation medical system controllers may use this data to control the volume contained in the reservoir.

Abstract: An adapter pod for use in a medical perfusion system having a data communications network with a plurality of connection points each having a substantially identical network connector. The adapter pod includes a housing and a common connector associated with the housing which is adapted to be connected to one of the network connectors and which has a connector configuration. A device connector is also associated with the housing, is adapted to be connected to a perfusion device, and has a configuration different than the connector configuration of the common connector. A controller is disposed within the housing and is adapted to generate messages in the form of digital data packets.

Abstract: According to one embodiment of the invention, a method of operation involves concurrently receiving spread-spectrum wireless signals from a plurality of sources by a listening device for a hearing-impaired user. These spread-spectrum wireless signals comprise audio in a digital format. The audio is filtered so as to retain audio within a specified audible frequency range set by the hearing-impaired user. The filtered audio is converted into an analog format, and thereafter, is subsequently output for perception by the user. This provides a cost-effective solution for the hearing-impaired in order to avoid unwanted ambient noise normally amplifier by conventional hearing aids.
