BIEL's Patents provide for many ActiPatch Modifications

Door open for Iontophoresis/Dielectrophoresis

"Optionally, the extra output signal 334 may provide control by enhancing the electromagnetic field for directed movement of chemical or pharmaceutical molecules in tissue, such as silver ions, for infection control. The enhanced electromagnetic field may be non-uniform in such a way as to direct movement of polar molecules, a method known as dielectrophoresis. Alternatively, the enhanced electromagnetic field may induce an electric field, which directs the movement of ions, a method known as iontophoresis."


Door open for Adjustable Pulsing rates

"An input 332 may be provided to receive external signals, for example, that alter the electromagnetic pulse duration, duty-cycle or pulse repetition rate of the electromagnetic field generated."


Door open for a Enhanced Power ActiPatch

"A high voltage generator (not shown) may be included to increase the intensity of the radiated field. The high voltage generator may produce less than 30 VDC and may be synchronized to allow energy transforming action between therapy pulses, so that therapy pulses are not affected by the energy transformation action. Energy transformation could comprise connecting the battery to an inductive coil for a brief duration, and then switching the coil into a diode or rectifier and capacitor. The capacitor accumulates charge at a higher voltage than the battery. When voltage on the capacitor reaches a predetermined value, the capacitor may be discharged into the frequency generator for producing a therapy pulse."


Door open for a Rechargeable ActiPatch

"Referring again to FIG. 3, the power source 324 may be direct current (DC) and preferably less than approximately 10 VDC. The power source may be rechargeable. The rechargeable power source may be a battery of the lithium metal hydride or lithium ion or lithium polymer technology that may be recharged from an external source, including a sine wave field generator proximate the antenna 310 or separate coil (not shown) for the non-contacting induction of power from the external source into the therapeutic device. Current induced in the antenna or separate coil may be rectified and supplied as a reverse current to the rechargeable power source until the power source reaches a predetermined terminal voltage or case temperature."


Door open for a Different Frequency ActiPatch

"In some implementations, the electromagnetic therapeutic device may operate in the frequency range of 3-30 MHz and application of the electromagnetic energy may be pulsed to maximize the therapeutic effect of the field. Pulses of 100 microsecond (µS) pulse duration at intervals of 1 millisecond (mS) (a pulse repetition rate of 1000 Hz) may be preferable. In order to reduce heating of the tissue, the electromagnetic field strength may be limited to less than 100 micro-Watts per square centimeter (µWcm-2) as measured proximate the surface of the tissue. FIG. 4B illustrates a resulting output 412 from the antenna. The electromagnetic field 414 is radiated from the antenna only when the enable signal 410 is at a logic high."
