Abstract: A caddy device for carrying and organizing articles being transported in a vehicle. The caddy is user-configurable to one or multiple individual compartments for optimizing their dimensions for carrying, holding and organizing articles such as filled shopping bags or food and drinks. Employing multiple dividers the device may be deployed to numerous different positions to adjust the compartment size. An optional cooler bag for transport of cold items is also engagable within the compartments.

Abstract: A carrying, holding and organizing system for articles such as filled shopping bags, the system including a multi-compartmented caddy that can be moved into a variety of positions and configurations. The caddy is also preferably collapsible so that its end panels and intermediate dividers form a stack. The end panels of the caddy can preferably be folded downward to provide extra support when the endmost caddy compartments are not occupied. In addition the divider panels can be folded downward to provide additional configurations suitable for different sizes and kinds of articles. The device is particularly adapted for holding shopping bags, various personal items, files and beverage containers in a moving vehicle.

Abstract: A joystick system is designed to provide a modified digital representation of the setting of a joystick potentiometer. The system operates to compensate for non-linearities and offsets in the joystick response, or may be used to enhance or vary the joystick response to a non-linear form. This is accomplished by supplying the output voltage of the joystick to an analog-to-digital converter, the output of which then is supplied to a lookup table. The lookup table output is provided to a counter. In one mode of operation, the counter counts down to zero at some multiple of a sample rate. When the counter reaches a zero count, the time interval representative of the joystick position is indicated; and the corrected or enhanced position is indicated by this output.

Abstract: A system is provided for digitizing the setting of a potentiometer of the type used in an analog joystick for computer games. The analog output of the potentiometer is applied to one of two inputs of a voltage comparator. When a readout of the joystick position is desired, a "write" input is applied to a counter to permit it to commence counting at a predetermined frequency from an initial or zero count. The digital outputs of the counter are coupled to the inputs of a digital-to-analog converter, the output of which is coupled to the second input of the voltage comparator. When the count in the counter produces a voltage at the output of the digital-to-analog converter corresponding to the voltage setting of the potentiometer, the comparator provides an output signal. The time delay from the time the write pulse occurs until this signal is obtained is representative of the potentiometer setting.

Abstract: A joystick system provides a digital representation of the setting of a joystick potentiometer. The voltage of the joystick is supplied to an analog-to-digital converter, the output of which then is used to load a counter. In one mode of operation, the counter counts down to zero at some multiple of the sample rate. When the counter reaches zero, the time interval representative of the joystick position is indicated; and this output is indicative of the joystick position. In an alternative mode of operation, the counter is used as a data latch and the joystick position is digitally read from the counter, which keeps the data latched until the next sample cycle from the joystick position.
