Title: Using state sending device and method
Inventor: MAEMURA HIROYUKI
IPC: G06F13/14
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To send the information to a host computer to show whether a device is currently used by securing the electrical connection between a power supply and a pull-up resistance when a device using state is set and then securing no electrical connection between those power supply and resistance when a device non-use state is set respectively. SOLUTION: When a CPU 14 actually uses a device 11, it stores the signals of L or H levels in the registers 15 and 17 in response to the data which are sent to a host computer 13 and also stores a signal of an L level in a register 19. If the device 11 is not actually used, the CPU 14 stores a signal of an H level in the register 19. The buffers 16 and 18 output the signals stored in both registers 15 and 17 to a signal line of a USB standard. One of both ends of a gate 22 is connected to a pull-up power supply 20 with the other end connected to one of both ends a pull-up resistance 21. Then the gate 22 becomes conductive when a signal of an L level is stored in the register 19 and then becomes non- conductive when a signal of an H level is stored in the register 19.

IPC: G05B15/02
Filed: 1985-11-25
Abstract: PURPOSE:To attain the simultaneous control of many loads by setting plural addresses at a part to be controlled and securing variation of one or more addresses among those set ones. CONSTITUTION:The 1st address detecting means 2a detects its own address, i.e., an individual address. While the 2nd address detecting means 2b detects a group address. Thus a part 2 to be controlled is activated by the address signal corresponding to its own address as well as the group address signal. Then it is decided that the part 2 belongs to a certain group address. For transmission signals to be used, the address signals and the control signals of group A and B and the part 2 are arrayed successively at the fixed intervals. The group A is first called out and the parts 2, 3...n belonging to the group A and to be controlled are activated all at once. Then the load to be connected to the group A itself is controlled by the immediately subsequent control signal. As a result, all loads belonging to the group A are actuated all at once. Then the group B is called out and undergoes the same control as the group A.
