A process andor system that extracts selected information from e. The video coder may encode or decode the bin using context-adaptive binary arithmetic coding. When the process and developer cartridges are mounted to each other, the developer cartridge is disposed above the first developer accommodating portion and at a side of the second removed developer accommodating portion. The first socket is located on the first surface. The weakly conductive property of the electrode enables the prevention of undesirable electrostatic discharge, user skin irritation and electrode corrosion caused by direct contact between the electrode and the user’s skin and also exhibit’s a substantially higher sensitivity than electrodes covered with an insulative material. Further, it is possible to measure vibration over a wide bandwidth.
