  • Patent number: 11495840
    Abstract: A battery pack may include a plurality of battery cells, a cell retainer and a heat exchanger assembly. The cell retainer may define a plurality of cell reception slots configured to retain respective ones of the battery cells. The cell retainer may define an enclosure that fixes the battery cells and is not penetrated by any cooling apparatus. The cell retainer may be in thermal communication with the battery cells to transfer heat away from the battery cells. The heat exchanger assembly may be in thermal communication with the cell retainer and external to the cell retainer to at least passively transfer heat away from the cell retainer while the battery pack is operated in a discharge mode. The cell retainer may include a thermally conductive material capable of transferring heat to the heat exchanger assembly and also storing at least some of the heat.

  • Patent number: 11260218
    Abstract: A garment worn by the patient is provided. The garment has a first module electrically connected to a second module. The first module has a first sub-control unit electrically connected to a first electrode and a second electrode placed at a first muscle and a third electrode and a fourth electrode placed at a second muscle. The sub-control unit is electrically connected to a master unit. The first muscle is stimulated with a first stimulation signal without shortening the first muscle by sending the first stimulation signal to the first electrode placed. The stimulation of the first muscle relaxes the second muscle.

  • Publication number: 20200197689
    Abstract: A garment worn by the patient is provided. The garment has a first sub-control unit electrically connected to a first electrode and a second electrode placed at a first muscle or first nerve of the patient. The first sub-control unit is electrically connected to a master unit. A fifth electrode is provided placed at a head of the patient that measures a brain voltage signal from a brain of the patient. The fifth electrode sends the measured brain voltage signal to a second sub-control unit or the master unit. A sixth electrode is placed adjacent to a heart of the patient that measures a heart signal from the heart of the patient. The second sub-control unit or the master unit analyzing the measured brain voltage signal and/or heart signal to determine which muscle to stimulate. The master unit adapts a first stimulation signal to the first sub-control unit based on the measured brain voltage signal or heart signal.

  • Publication number: 20200197688
    Abstract: A first electrode, a second electrode, a third electrode and a fourth electrode are placed on a head of the patient. The electrodes are electrically connected to a master unit or sub-control unit that generates a first stimulation signal, during a first time period, to the first and second electrodes to stimulate the brain inside the head. The third and fourth electrodes receive a first brain signal, during a second time period, and forwards the first brain signal to the master unit or sub-control unit which analyzes the first brain signal and adapting a second stimulation signal based on information in the first brain signal.
