  • Publication number: 20250032322
    Abstract: A method for providing a negative pressure wherein a pump is cycled on and off to achieve a target negative pressure, which is set slightly lower than the therapeutic negative pressure. A device determines the actual pressure by averaging samples which may occur at a different rate than the pump cycle.

  • Publication number: 20230183949
    Abstract: A tooth assembly having an adapter, a tooth, and a pin. The adapter and the tooth each have a first portion and a second portion. The first portion of the adapter is adapted to be combined with an earth-digging implement. The second portion of the adapter is adapted to be combined with the tooth. The second portion of the adapter has an opening adapted to receive an engagement member extending from the second portion of the tooth. The first portion of the tooth is adapted to engage the material being displaced by the implement and the second portion is adapted to be combined with the adapter. The second portion of the tooth has an opening adapted to receive an engagement member extending from the second portion of the adapter. The pin is inserted through openings in both the adapter and the tooth to secure the two components together during operation.

  • Patent number: 8242763
    Abstract: A DC to DC converter has first and second transistor coupled at a first node and coupled between first and second power supply terminals. An inductor has a first terminal coupled to the first node and a second terminal coupled to an output terminal for receiving a variable load. Transistor drive circuitry controls conduction of the first and second transistor in a non-overlapping conduction operation. A duty cycle controller controls a duty cycle for the first transistor and the second transistor. Control circuitry determines a mode of operation by monitoring cycles of operation and detecting a predetermined pattern of cycles in which inductor current becomes negative. A first mode of operation permits both the first transistor and the second transistor to alternately conduct and a second mode of operation does not permit the second transistor to conduct during each cycle when the inductor current is reduced to substantially zero.

  • Publication number: 20060290464
    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.
