A weight training apparatus using hydraulics or pneumatics for applying positive and negative resistance closer to a user's maximum capacity throughout a lift is provided. The weight training apparatus allows for weight training without weights. The weight training apparatus may provide a more effective and safer mechanism for training than conventional techniques.

Devices, systems and methods for the preparation of an oxygenate compound or mixture of oxygenate compounds suitable for use in internal combustion engines are disclosed. An internal combustion engine system includes: a fuel system including an oxygenate compound synthesis device including a reactor including a catalyst, the oxygenate compound synthesis device being configured to convert at least a portion of a feedstock to an oxygenate compound or a mixture of oxygenate compounds; and an internal combustion engine configured to initiate combustion through compression or high energy discharge, the internal combustion engine including: a fuel injection system configured to provide fuel injection, and a cooling system configured to cool the internal combustion engine, the internal combustion engine being configured to heat the oxygenate compound synthesis device using heat from the cooling system of the internal combustion engine. Applications of the devices, systems and methods are also disclosed.

An imaging system comprising a multi-channel matrix array of CCD devices wherein a plurality of sensor cells (pixels) in each channel are subdivided and operated in discrete intercoupled groups or subarrays with a readout CCD shift register terminating each end of the channels. Clock voltages are applied to the subarrays and are manipulated to selectively cause charge signal flow in each subarray in either direction independent of the other subarrays. More particularly, the array is divided into six independent subarrays, three on each side of the array, such that each channel common to three subarrays is divided into three sections of three sensor cells each. By selective application of four phase clock voltages, either one, two or all three of the sections cause charge signal flow in one direction, while the remainder cause charge signal flow in the opposite direction. This creates a form of selective electronic exposure control which provides an effective variable time delay and integration of three, six or nine sensor cells or integration stages. The device is constructed on a semiconductor sustrate with a buried channel and is adapted for front surface imaging through transparent doped tin oxide gates.
