The garment has a first sub-control unit or master unit electrically connected to a first electrode and a second electrode placed at a first muscle or first nerve and a third electrode and a fourth electrode placed at a second muscle or second nerve. The garment has sensors attached to the garment and electrically connected to the first sub-control unit or master unit. The sensors measure position, electrical signals or movement of the patient wearing the garment. The first sub-control or the master unit receives information about the position or movement and comparing the position, electrical signals or movement to an interval of pre-stored desirable positions, electrical signals levels or movement. When the position, electrical signals or movement is outside the interval, the master unit sends through the first sub-control unit a stimulation signal to the first muscle to cause or facilitate a contraction of the first muscle.

Medical therapy arrangement for applying an electrical stimulation to a human or animal subject

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.

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.

Apparatus for providing battery pack cooling

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.

The stimulation of the first muscle relaxes the second muscle. A measuring unit (U) of the master unit determines a first current value flowing from the first electrode through the first muscle to the second electrode and sends the first current value to a central processing unit (CPU).

A system may include sensor equipment, a local yard maintenance manager and a remote yard maintenance manager. The sensor equipment includes one or more sensors disposed on a parcel of land. The local yard maintenance manager may be disposed proximate to the parcel and configured to interface with the sensor equipment to monitor growing conditions on the parcel. The remote yard maintenance manager may be disposed remotely with respect to the parcel and configured to interface with the sensor equipment.

Distributed intelligent grounds management system

A battery charging system may include one or more battery packs each of which includes control circuitry and a switching assembly, and a charger including a power section and a charge controller. The charge controller and/or the control circuitry may be configured to direct operation of the switching assembly to control charging of the one or more battery packs.

Battery pack interface system

The method is for making an electric motor more efficient by iteratively changing when a processor sends activation signals to transistors to minimize a current required to rotate a rotor at a constant rotational speed. The method is also for changing a rotational direction of the rotor by switching the order in which activation signals are sent to the transistors.

Method for making a motor quieter

A riding lawn care vehicle may include a battery power source, an electric drive motor, at least one blade drive motor, a current sensor, and a controller. The electric drive motor may be powered by the battery power source. The electric drive motor may be operably coupled to wheels of the riding lawn care vehicle to provide drive power for the riding lawn care vehicle. The at least one blade drive motor may be powered by the battery power source. The at least one blade drive motor may be operably coupled to at least one cutting blade of the riding lawn care vehicle. The current sensor may be disposed to monitor total current drawn from the battery power source. The controller may receive total current data from the current sensor and provide feedback to an operator of the riding lawn care vehicle based on the total current data.

Battery powered lawn care vehicle with drive efficiency indicator

The method is for making a brushless direct-current (DC) motor quieter. A predetermined high frequency pulse width modulated (PWM) signal is generated. The PWM signal is sent to a first filter. The first filter truncates the PWM signal to provide the PWM signal with a rise time. The rise time allows transistors connected thereto to open smoothly. A second filter is provided that has a non-polarized capacitor. In a coil switching process, the non-polarized capacitor operates as a voltage or current absorption circuit between driving transistors. The coil switching process creates transient energy of voltage transients. The non-polarized capacitor absorbs the transient energy.
