The invention provides wearable devices for effecting transcranial magnetic stimulation to be used by patients who have suffered brain injuries. Permanent magnets are shifted or rotated to deliver a time-varying magnetic field, preferably about the locus of the injury. In an embodiment, the strong magnetic fields of the permanent magnets are directed to the injured area for therapeutic purposes. A novel mechanism is provided that uses a small battery-powered electromagnet to interact with the weak peripheral magnetic fields of the permanent magnets and to shift the permanent magnets between two or more stable positions. As a result, a lightweight, quiet, wearable device with low power consumption is provided.

Time-varying magnetic field therapy using multistable latching mechanisms

A method and an apparatus are disclosed for extending the service life of a battery source by fully utilizing the energy in batteries and/or providing higher energy reserve using multiple batteries. An universal battery bank consists of an ensemble of possibly heterogenous batteries all connected in series to provide a usable operational energy source. For a universal battery bank consists on N batteries, the minimum operational voltage for the individual batteries (Vmin) can be lowered to Vmin/N on average, thereby extending the time interval between battery replacements and draining the individual batteries more efficiently. To exploit this power supply that may vary over a wide voltage range, electronics are designed to monitor the individual batteries, guard against excessive voltage and current, and provide constant current sources and/or constant voltage sources for various appliances.

Systems and methods for sleep apnea detection from breathing sounds

A method and a device are disclosed for an electronic neuron emulator for representing both passive and active electrical properties of a live neuron. The currents used to generate action potentials are derived from a pre-charged capacitor. The present invention provides for a more physiological state for testing neuroscience instruments such as the single-electrode voltage clamp and the patch clamp. The device can also include multiple pre-charged capacitors to represent ionic channels with more accurate physiologically parameters.
