A device for administrating electro-muscle stimulation (EMS) includes a flexible covering having a plurality of spaced apart electrodes (22). In a preferred embodiment the flexible covering is shaped like a belt (24) and is designed to encircle and be connected around a portion of a patient's body (506).

Augmentation of electrical conduction and contractility by biphasic stimulation of muscle tissue. A first stimulation phase has a first phase polarity, amplitude, and duration. The first stimulation phase, which acts as a conditioning mechanism, is administered at no more than a maximum subthreshold amplitude. A second stimulation phase has a second polarity, amplitude, and duration. The two phases are applied sequentially. Contrary to current thought, anodal stimulation is applied as the first stimulation phase, followed by cathodal stimulation as the second stimulation phase. In this fashion, pulse conduction through muscle is improved, together with an increase in contractibility. Furthermore, this mode of biphasic stimulation reduces the electrical energy required to elicit contraction. In addition, the conditioning first stimulation phase decreases the stimulation threshold by reducing the amount of electrical current required for the second stimulation phase to elicit contraction. The muscle tissue encompassed by the present invention includes skeletal (striated) muscle, cardiac muscle, and smooth muscle.

A liquid crystal display (LCD) is provided that comprises a rearward LCD substrate sheet that has an array of vias formed, where the vias provide electrical conduction between both sides of the rearward LCD substrate sheet. The number of vias in the array is substantially equal to or at least equivalent to a combination of a number of column drive lines and a number of row drive lines. The respective drive lines are connected to a corresponding via, such as on one side of the rearward LCD substrate sheet, and respective patterned conductors are connected to a corresponding via, such as on the other side of the rearward LCD substrate sheet. The patterned conductors provide a connection between respective drive lines and one or more corresponding drivers. In one example, this allows a “full bleed” display to be generated.

The invention is a chemically grown oxide layer which prevents dopant diffusion between semiconductor layers. The chemically grown oxide layer may be so thin that it does not form a barrier to electrical conduction, and thus may be formed within active devices such as diodes or bipolar transistors. Such a chemically grown oxide film is advantageously used to prevent dopant diffusion in a vertically oriented polysilicon diode formed in a monolithic three dimensional memory array.

Provided is an image sensor having a pixel includes a photoelectric conversion element; a capacitor which is connected between the photoelectric conversion element; a reset circuit which resets a potential of a node between the photoelectric conversion element and the capacitor; an amplifier circuit which outputs a signal corresponding to the potential of the node; and a switch which controls electrical conduction between the amplifier circuit and a vertical signal line. When the node is brought into an electrically floating state, the potential of the optical signal is stored in the node in a state of being inverted. When an optical signal is detected while the potential is stored in the node, the potential of the node increases in accordance with an output potential of the photoelectric conversion element, and thus the potential of the node corresponds to a difference in potential between the optical signals in different light-receiving periods.
