Abstract: A container lining device and a method for using the same are disclosed. The container lining device for being installed in a container includes a sealed rectangular bag made of a pliable material and having a single-layer or multi-layer bag wall. The bag has a front side centrally provided with a valve, and a rear side provided transversely and longitudinally with plural pulling straps whose free ends extend out from edges of the bag. Liquid or fluid cargo is delivered into and out of the container lining device through the valve. After unloading, the container lining device is taken out through an opening of the container and replaced by another such container lining device to facilitate reloading. The container lining device facilitates saving the time and cost otherwise required for cleaning the container, increasing the utilization rate and service life of the container, and lowering overall cargo transportation costs.

Abstract: A universal collapsible, reusable, stackable, flexible shipping container for cargo including dry materials to slurries to fluids. This invention comprises using a flexible outer layer, foldable corner components, and flexible and foldable core section for insertion into the flexible outer layer and flexible container member for insertion into the flexible outer layer. This container utilizes components which may be used as a system either in combination or as individual elements with the flexible outer layer.

Abstract: A piece of exercise equipment includes an electronic game of chance connected thereto. A switch or other device may also be connected to the combination system to operate the electronic game of change when the piece of exercise equipment is in use. The combination system also includes a controller which detects a combined action of playing the electronic game of chance and using the exercise equipment. The system electronically connects the gambling device to the piece of exercise equipment and detects when an operator is using both the exercise equipment and the electronic game of chance simultaneously.

Abstract: A frequency agile signal generator provided for emulating a communication signal of predetermined frequency and modulation characteristics including frequency hopping. The signal generator includes a digital controller such as a microprocessor or microcomputer for generating digital command signals specifying the desired characteristics of the output signal. In response to the digital command signals, a base digital frequency signal representing the desired base or center frequency of the output signal is generated by a number controlled oscillator in response to a digital frequency control signal. The digital command signals also control the generation of an analog modulation signal having desired modulation characteristics.
