Non-regular electrical stimulation patterns for treating neurological disorders

ActiveUS20100152807A1Improves stimulation efficiencyMinimize currentHead electrodesExternal electrodesHigh rateElectricity
Systems and methods for stimulation of neurological tissue generate stimulation trains with temporal patterns of stimulation, in which the interval between electrical pulses (the inter-pulse intervals) changes or varies over time. Compared to conventional continuous, high rate pulse trains having regular (i.e., constant) inter-pulse intervals, the non-regular (i.e., not constant) pulse patterns or trains that embody features of the invention provide a lower average frequency.

Middle or Large-Sized Battery Module Employing Impact-Absorbing Member

ActiveUS20090311581A1Low mechanical safetyDeteriorating safety of batteryPrimary cell to battery groupingFinal product manufactureCapacitanceElectrical connection
Disclosed herein is a battery module using battery cells each having an electrode assembly mounted in a battery case including a resin layer and a metal layer as unit cells, wherein each battery cell has a thin upper end, including a sealing part, which is formed at a region where electrode terminals are placed, and an impact-absorbing member is mounted at the upper end of each battery cell. The battery module according to the present invention prevents the weak upper parts of battery cells, such as electrode terminals and sealing parts, from the breakage of the battery module or the occurrence of a short circuit in the battery module due to the movement of the battery cells caused by dropping of the battery module or application of external impacts to the battery module. Furthermore, the battery module according to the present invention is constructed in a structure in which the battery module can be flexibly extended and contracted depending upon desired electrical capacity and output, wires used to electrically connect components constituting the battery module are compact, and the electrical connection between the components of the battery module is stably accomplished.

Heat radiation structure for secondary battery module, and switching board and secondary battery module having the same

Disclosed herein is a heat dissipation structure that is capable of effectively dissipating heat generated from switching elements for controlling overcharge, overdischarge, and overcurrent of a high-output, large-capacity secondary battery module or pack having a plurality of unit cells electrically connected with each other such that the unit cells can be charged and discharged. A switching board has the heat dissipation structure and the switching elements, which are mounted on a printed circuit board. A secondary battery module includes the switching board. The size of the heat dissipation structure according to the present invention can be effectively increased or decreased depending upon desired electrical capacity and output. Also, the heat dissipation structure provides high heat dissipation efficiency even though the heat dissipation structure is compact.
