A single-ended to differential converter uses a cross-coupled latch that maximizes the output zero-crossing symmetry and is self compensating over PVT variations. An in-phase driving signal is provided by an always-on transmission gate coupled to the input. An out-of-phase driving signal is provided by an inverter coupled to the input. The in-phase and out-of-phase driving signals each drive an input of the cross-coupled latch. The in-phase driving signal from the always-on transmission gate starts to bring the cross-coupled latch into conduction, and when the out-of-phase driving signal arrives, the simultaneous driving of the cross-coupled latch causes a rapid and symmetric transition of both outputs of the cross-coupled latch.

Accelerometer offset is reduced by forming mass support structures within an inner periphery of the mass, affixing the mass support structures to the substrate by at least one anchor positioned near the mass' center of mass, and affixing the sensing fingers proximate to the anchor. The mass support structures can be affixed to the substrate using a single anchor or multiple anchors that are positioned close together. The sensing fingers can be affixed to the substrate or to the mass support structures. The mass is typically suspended from within its periphery but toward its outer periphery.

A suspended-load backpack designed to permit the load to move relative to the backpack frame during walking and running so that the large movements between the load and the frame of the backpack reduce the fluctuations of absolute vertical motion of the load. Because the hip (and thus the pack frame) go up a down a good deal during walking, a large relative movement between the frame and the load reduces the absolute excursion of the load. This movement may be, in turn, transferred to a motor through, for example, a rack and pinion gear, to convert the mechanical movement to electrical energy. The movement may also be converted to electrical energy by using an electroactive polymer (EAP) to connect the suspended load to the frame. Such designs allow the load to move in a controlled fashion to prevent the patient from losing his or her balance as the load moves up and down along the backpack frame. Such movement of the suspended-load relative to the frame also reduces the forces on the wearer's shoulders while walking or running, thus reducing the likelihood of orthopedic injury.

Data transfer scheme wherein data transfer rates can be effectively doubled with no increase in the clock speed of the interface. This is accomplished by allowing more than one data transfer to occur on a single clock cycle. This transfer scheme increases the transfer rate of the interface by multiplexing two data groups on the same interface.
