A device (10, 50, 60, 70, 80, 90) is used to apply an electric pulse or spike to a patient to treat the patient. The device can have a series of preset treatments programmed therein. A user can select a treatment from menus displayed on a display (100). The impedance of the skin and underlying tissue to be treated can be measured prior to the treatment to locate active areas on the skin for treatment. The impedance measurement can be made at a sufficiently low level to avoid treatment of the patient that could cause a change in the impedance. A phase detector can be used to isolate the capacitance value in the impedance. The charge delivered to the patient can be measured and the device can adjust the charge as the skin impedance varies during treatment to deliver uniform charges to the skin. A variety of probes can be used with the device, with the device automatically detecting the type of probe attached. Multiple electrodes can be used on the probe, which allows the active areas in contact with the probe to be identified prior to treatment to allow the treatment to concentrate on the active areas.

A low voltage of the order of or one to three volts instead of an intermediate VPASS voltage (e.g. of the order of five to ten volts) is applied to word line zero immediately adjacent to the source or drain side select gate of a NAND flash device to reduce or prevent the shifting of threshold voltage of the memory cells coupled to word line zero during the programming cycles of the different cells of the NAND strings. This may be implemented in any one of a variety of different self boosting schemes including erased areas self boosting and local self boosting schemes. In a modified erased area self boosting scheme, low voltages are applied to two or more word lines on the source side of the selected word line to reduce band-to-band tunneling and to improve the isolation between two boosted channel regions. In a modified local self boosting scheme, zero volt or low voltages are applied to two or more word lines on the source side and to two or more word lines on the drain side of the selected word line to reduce band-to-band tunneling and to improve the isolation of the channel areas coupled to the selected word line.

Data to be impressed upon the average value of a chrominance portion of a block, is replicated at least once. The original and each replica is impressed on blocks in the same block position of separate frames. The frames that have like-positioned blocks that are carrying the same data are considered to be a group. Specific blocks of the frame may be embedded with a particular known data sequence rather than user data. Each group may employ a different known sequence. Instead of simply repeating the data for each like-positioned block of a group, the amount added to the average value for each such block may be changed slightly from frame to frame in group, even when the complexity of the blocks is the same. At a receiver, the multiple instances of the same data bit are extracted and combined to form a single received bit.
