摘要： The invention uses the conventional PC game port as a port for a digital game input device, employing a Digital Game Port (DGP) protocol which uses the four discrete or button lines and a single analog line (one of four) on the conventional game board to form a dual serial port. Data from a DGP control device is packetized with each packet consisting of 13 bytes of data. The packets or blocks are then grouped into frames. A frame consists of two blocks of data. A total of two frames are transmitted to the driver for each driver request. The 13-byte data block is divided between six one byte analog values and four bytes of digital data, with three bytes that identify and define the device. This device definition and identification is unique. By sending the device identification and configuration to the driver, the driver can determine not only the presence of the device but also very specific aspects of the device. The hardware configuration of the cable enables the driver to uniquely identify the first unit connected to the host computer as the master unit. The driver identifies the other units, if any, as slave units. Up to 3 additional slave units may be chained from the master digital game port input device by such cables.

摘要： The invention comprises a controller that includes a base, a handle mounted on the base, a flipper switch mounted at a distal end of the handle, and having two optical accelerometers mounted within a cavity of the handle for detecting the force applied to the controller. Each optical accelerometer includes a light source, a light detector, and a shield having a pattern formed thereon that varies from the first end of the shield to a second end of the shield so as to allow an increasing amount of light to pass through the shield as the shield moves from its first end to its second end. The shield is pivotally mounted between the light source and the light detector so that the force applied to the handle causes the shield to pivot thereby allowing a varying amount of light to be passed from the light detector through the shield to the light source. Thus, the amount of light detected by the light source is a function of the amount of deflection of the shield, which is further a function of the amount of force applied. The pattern formed on the shield can take a variety of forms. In the preferred embodiment the pattern is a progressive grey scale pattern that goes from a ten percent grey scale at the first end to a ninety percent grey scale at the second end. The pattern can also comprise a slot that has a width that varies increasingly from the second end to the first end of the shield.
