Systems and methods are provided for grounding a person lying on a mattress. Such grounding may connect a user's body to the earth and enable electrical discharge off the human body. The systems and methods may include a mattress pad having conductive inner and outer layers. The mattress pad may also include an insulating interior layer having a flame-retardant layer, a first foam layer, and a second foam layer. The mattress pad may also include a conductive edge ribbon configured to electrically couple the inner and outer layers, as well as a grounding terminal. A grounding cable may be realized to ground the inner layer, outer layer, and conductive edge ribbon. The grounded mattress then grounds the human body, allowing it to get closer to a natural electrical potential. This can reduce static electricity, static shocks and enhance quality sleep. The mattress will also improve shielding from electromagnetic fields (EMFs).

A renal failure therapy system having an electrically floating fluid pathway is disclosed. The example system includes a dialyzer, a blood circuit in fluid communication with the dialyzer, and a dialysis fluid circuit in fluid communication with the dialyzer. The system also includes an electrically floating fluid pathway comprising at least a portion of the blood circuit and at least a portion of the dialysis fluid circuit. The only electrical path to ground is via used dialysis fluid traveling through the renal failure therapy system to earth ground. The disclosed system enables at least one electrical component in the at least a portion of the dialysis fluid circuit of the electrically floating fluid pathway to be electrically bypassed.

A drive device includes a neutralizing device electrically connecting a shaft and a housing. The shaft extending in the axial direction along a rotation axis has a shaft wall. The shaft wall is arranged inside a shaft tubular portion that has a tubular shape surrounding the rotation axis and expands in the radial direction. The housing has a columnar portion extending to one axial side. Portions of the neutralizing device and the columnar portion on the one axial side are arranged on the other axial side of the shaft wall in the shaft tubular portion. The neutralizing device contacts the columnar portion and at least one of an inner peripheral surface of the shaft tubular portion and the other axial end surface of the shaft wall.

Load-bearing apparatus/systems for location in the vicinity of energized power lines are provided. The apparatus includes a base member. The base member has an upper layer and a backing surface layer. An uppermost surface of the upper layer is adapted to support on it at least power line workers and/or related stringing equipment. At least the uppermost surface of the upper layer is adapted to be electrically conductive. Methods for forming the apparatus are also provided.

Embodiments of the disclosed subject matter generally relate to electrically grounding a user who may be working in an environment where static electricity might otherwise build up on the user and damage sensitive electronic devices being handled by the user. Embodiments include attaching an electrocardiogram (ECG) electrode to the user's skin and removably attaching the ECG electrode to an electrical conductor which may be detachably connected to a flexible base disposed on the outside of and under the user's shoe.
