    摘要: A user input system for inputting computer signals, such as a joystick, has an elongated member or handle that is movably received by a housing. The handle is capable of moving in at least three perpendicular directions, i.e., along X, Y and Z axes, and is capable of being rotated about at least one of the three axes. In a first embodiment, a pair of light emitting diodes ("LEDs") are mounted at an end of the handle and oriented toward the interior of the housing. The LEDs are strobed to alternately project light downward into the housing. A light detecting element, such as a two-dimensional position sensing device ("PSD"), two one-dimension PSDs, or a four quadrant photodiode, is positioned opposite the LEDs, and mounted to the housing to receive the light from the LEDs to produce signals. The signals are converted from analog to digital and input to a microprocessor. The microprocessor, employing trigonometric methods, calculates the position and orientation (i.e., rotation) of the handle and outputs the coordinates to a host computer. The joystick preferably includes switches that produce signals and a slidable member that produces a variable signal, all of which are also output to the computer. In a second embodiment, the LEDs are mounted to the housing to project the light upward and the light detecting unit is mounted at the end of the handle.

    摘要: A digital joystick operates in a digital mode or an analog emulation mode. In the digital mode, the joystick generates digital data indicating the position of a control stick and the status of buttons and transmits the digital data to the computer. The joystick may be coupled to the computer through a game port or a conventional interface port. Computer software operating within the computer can receive digital data directly from the joystick if it is operating in the digital mode. When in the analog emulation modes the joystick emulates resistances related to the position of the control stick. The emulated resistance data emulates the value of corresponding resistances in a conventional joystick. The resistance values may be derived from a programmable resistor, a programmable impedance, or a programmable current source. Multiplexers may also be used to couple the appropriate resistance value to the conventional game port input.

    摘要: A game port interface is disclosed which permits bidirectional communication between a game port and a peripheral device. In one embodiment, the peripheral device is a digital joystick and the game port sends commands to the digital joystick. The game port interface includes one or more timers whose inputs are coupled to resistances within the joystick. Also coupled to the timer inputs are capacitors such that the resistors in the joystick form a charging network with the capacitors in the game port interface. When an output instruction to the game port is executed, the capacitors coupled to the timer inputs are charged to a predetermined voltage. The timer input is also coupled to an inverter within the joystick. The output of the inverter switches to a low logic level when the timer input is charged above a logic threshold. The output of the inverter is coupled to an interrupt input on a microprocessor within the joystick. The microprocessor interprets one or more interrupts as commands and takes appropriate action. In one embodiment, the first interrupt causes the digital joystick to transmit data corresponding to the position of the joystick. If a second interrupt is transmitted to the joystick while the first interrupt is being processed, the second interrupt is interpreted as a second command. Each interrupt transmitted to the joystick while the joystick is processing the previous interrupt is interpreted as a new command. For example, if the joystick is processing the second interrupt, and a third interrupt request is detected at the interrupt input, this is interpreted as a third command. The digital joystick of the present invention is also capable of operating in an analog emulation mode. The game port can send similar commands using the interrupt circuitry described above to the joystick while in the analog emulation mode.

    摘要: A digital joystick coupled to a conventional computer game port tests for the presence of electrical circuitry to support two joysticks and dynamically configures the digital data for transmission to button inputs for either one or two joysticks in the game port. The digital joystick configures the data for transmission to three or more button input lines on the game ports if it detects the second joystick circuitry, and configures the data for transmission to only two button inputs corresponding to the first joystick if it does not detect the second joystick circuitry. The digital joystick generates a clock which is coupled to one button input in the game port. The remaining button inputs are used to transfer data. Within the computer, the system determines the presence of electrical circuitry for the second joystick and is configured to accept data from both joystick inputs that are active. The computer is configured to accept data from only the first joystick if the second joystick input is not active. The system automatically configures the data to correspond with the electrical circuitry present within the game port without any intervention by the user.

    摘要: An apparatus and a method for controlling a feedback force applied by a joystick to a user gripping the control handle of the joystick. In the preferred embodiment, a light path between an infrared light source and a light sensor is interrupted by a user gripping the handle of a joystick. The output signal from the light sensor is employed by a processor to control the feedback force. When based upon the output signal, the processor determines that the user has just gripped the control handle, the processor enables the feedback force to increase slowly, over a sufficiently long time to enable the user to firmly grip the control handle before the feedback force becomes very strong. The processor immediately disables generation of the feedback force as soon as the user releases the control handle. The processor periodically energizes and then de-energizes the light source, determines an average value of the output signal when the light source is both energized and de-energized, and based upon a comparison of these average values, determines if the user's hand gripping the control handle has interrupted the light path between the source and light sensor. Additionally, the processor checks for a failure of the light source, and if detected, halts the generation of the feedback force.

    摘要: An OFDM wireless communication system with an access point and a plurality of remote user terminals estimates an uplink channel. The access point receives training symbols transmitted by the user terminals. Each training symbol includes pilot symbols associated with phase offset estimation OFDM sub-carriers. The phase offset estimation sub-carriers include subsets of sub-carriers associated with each respective user terminals. Each subset is used exclusively by the associated user terminal during channel estimation. The channel estimation sub-carriers are used by all user terminals. For each terminal the access point estimates symbol-specific phase offsets specific to the user terminal using the received pilot symbols associated with the user specific subset of the phase offset estimation sub-carriers. The access point also estimates the uplink channel using the user-terminal-symbol-specific phase offset estimates and the received symbols.

    摘要: A user terminal for wireless communication with a remote access point can include a mapping module, a delay module, a transmit module, and a directional antenna. The mapping module can be used to map one or more input data bits to an uplink symbol. The delay module can be used to apply a delay to the uplink symbol. The transmit module can be used to modulate the delayed symbol into a frequency channel. The directional antenna can be oriented along a dominant path to the access point, and the antenna is used to transmit the modulated symbol to the access point. The delay is chosen such that the transmitted symbol arrives at the access point simultaneously with a another symbol that is modulated into the frequency channel and transmitted by another user terminal.

    摘要: A force-feedback multidirectional input device includes a slider slidably supported by a support base and an operation knob joined to the slider. In a sliding operation, the slider operates in conjunction with actuating members included in a force-feedback unit. Therefore, a sense of force based on the sliding is fed back to the operation knob. Furthermore, the slider is elastically urged by coil springs toward an inner bottom surface of a housing space defined in the support base. In a depressing operation, the operation knob presses the support base downward against the urging force of coil springs. Therefore, a vertically movable member joined to the support base is moved downward along guide portions (convex rails and concave grooves). Thus, a push switch provided on a pedestal (circuit board) is pressed and activated by the vertically movable member.
