Patent number: 5793356Abstract: 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.Type: GrantFiled: July 31, 1995Date of Patent: August 11, 1998Assignee: Microsoft CorporationInventors: Mark K. Svancarek, Manolito E. Adan, Michael W. Van Flandern, John G. Pierce, Hajime Suzuki, Richard B. Kash

Patent number: 5724558Abstract: 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.Type: GrantFiled: July 31, 1995Date of Patent: March 3, 1998Assignee: Microsoft CorporationInventors: Mark K.

Patent number: 5722099Abstract: A bathing apparatus for disabled and aged is presented which allows bathing of a person in a seated position in a wheel chair. The bathing apparatus is hygienic because the caster rollers for the wheel chair are isolated from the bath water in a non-water-filled section of the apparatus thus avoiding contamination of the bath water, and can be operated with ease with one helper person. The bathing apparatus requires less water for a full bath compared with the conventional wheel chair bathing units, because the chair frames are designed to ride on the inside of the bath tub. This configuration is made possible by having a chair frame supported on a single support rod which can be pushed inside the bath tub through a cut-out provided on the bottom section of the tub unit. The support rod emerging from the bottom section into the bath water is sealed by a pair of sealing members which are pressed tightly around the support rod to eliminate leaking of the bath water from the tub unit.Type: GrantFiled: December 16, 1996Date of Patent: March 3, 1998Assignee: Sakai Medical Co., Ltd.Inventors: Hajime Suzuki, Yasuo Sekiguchi

Patent number: 5694153Abstract: 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.Type: GrantFiled: July 31, 1995Date of Patent: December 2, 1997Assignee: Microsoft CorporationInventors: Tetsuji Aoyagi, Takeshi Miura, Hajime Suzuki, Russell I.

Patent number: 5628686Abstract: 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.Type: GrantFiled: July 31, 1995Date of Patent: May 13, 1997Assignee: Microsoft CorporationInventors: Mark K.

Patent number: 5567222Abstract: A method of controlling slag coating in a steel converter in which slag is left in the converter after tapping, and a slag solidifying agent is added to the slag to form a coated slag which is used to coat the bottom and/or side wall surface of the converter. The method is performed bya) examining the composition of the slag at the tapping time;b) determining, based on the examined slag and through an equilibrium calculation using thermodynamic data, the amount of solidifying agent per unit weight of the slag necessary for maintaining the liquid volume fraction of the coated slag to a value not greater than about 40% at the planned tapping temperature of the next charge of steel;c) determining the amount of charge of the solidifying agent based on the calculated required amount of the solidifying agent and the amount of the slag remaining in the converter; andd) adding the calculated charge of the solidifying agent to the slag after tapping, to form a coated slag.Type: GrantFiled: March 21, 1995Date of Patent: October 22, 1996Assignee: Kawasaki Steel CorporationInventors: Katsunori Takahashi, Eizo Maeda, Hajime Suzuki, Sumio Yamada, Taichi Nakazawa, Yasuo Imaiida

Patent number: 5545259Abstract: In a dish washing machine according to the present invention, the contents of washing and rinsing are changed depending on dirt to prevent water from being uselessly used particularly if the degree of dirt on the dishes is low. Therefore, in the first drainage process in the latter part of the washing, the drainage is first started IS2-1). If 20 seconds have elapsed since the drainage was started, the drainage is stopped (S2-3). If the degree of dirt on the dishes is relatively high to select a sequence X (S2-4), drainage processing is performed on the basis of the contents of operations in the sequence X, after which the program proceeds to the rinsing process (S2-5 to S2-11).Type: GrantFiled: January 24, 1995Date of Patent: August 13, 1996Assignee: Sanyo Electric Co., Ltd.Inventors: Hajime Suzuki, Tetsuo Harada
