Title: Programmable cellular telephone and system
Inventor: SHIRAI KAZUHIKO
IPC: H04W8/26
Filed: 1996-06-04
Granted: 2005-12-06
Abstract: A module (P-code module) provides parameter information to a Number Assignment Module (NAM) in a cellular phone unit by processing a simple programming code (P-code) entered by the user through a telephone keypad. The P-code employs a flexible length telephone keypad coding that can be translated into programmable parameters of cellular phone products. Field identification numbers and look-up tables are used to shorten the P-code length for more frequently used information. To activate a cellular phone, the user provides product and serial number information to a dial- up access center which then generates a scrambled P-code for entry by the user. The P-code module within the processor unit of the cellular phone likewise descrambles, decompresses, and performs an integrity check on the sequence of digits being entered by the user. This P-code module reduces the technical requirements for programming a cellular phone purchased at the retail level such that a user can perform the necessary programming for activating the cellular telephone on a local telephone network. A security arrangement randomly generates two passwords when the cellular telephone is activated to prevent unauthorized reprogramming of the phones for use on other cellular telephone networks.

Abstract: A communication system (Fig. 2) for coordinated downstream diversity transmis-sion includes a central processing center (105) for selecting adaptive transmitter parameters and adaptive receiver parameters as to opti-mize the estimate of a transmitted data sym-bol received by a given mobile unit (e.g. 121) while constraining power output as well as ac-counting for interference to other mobile units (e.g. 122-125) within the propagation range of base units (110, 111, 112) controlled by the central processing center. The adaptive transmitter and receiver parameters are deter-mined from the solution of an eigenvalue for-mulation expressed in terms of the transmis-sion path characteristics between the mobile unit and the base unit as well as transmission signal sources and mobile unit process filters.

Abstract: A virtual reality space that can be shared by unspecified users world-wide is provided. When a URL is transmitted from a client terminal via a network, a three- dimensional virtual reality space composed of only basic objects of which basic states do not change and the IP address of a shared server terminal are sent from an information server and a mapping server to the transmitting client terminal. when the client terminal accesses the shared server based on the received IP address, information associated with avatars (update objects) representing users of other client terminals is transmitted from the shared server, displaying the virtual reality space reflecting the avatars on the client terminal. Consequently, the three- dimensional virtual reality space can be shared without changing the existing Internet.

Abstract: A pulse width modulated drive circuit drives a solenoid operated valve in response to an input voltage signal from a control apparatus.  The solenoid operated valve includes a coil that is energizable in response to energy received from the pulse width modulated drive circuit.  The pulse width modulated drive circuit includes a pulse generator stage and an output stage.  The pulse generator stage receives the input voltage signal from the control apparatus and a feedback signal from the coil which ultimately combine to form a control voltage in response to which the pulse generator stage generates a pulse width modulated signal whose duty cycle depends on the control voltage.   The output stage receives the pulse width modulated signal from the pulse generator stage and generates in response thereto a pulse width modulated output signal across the coil.  The pulse width modulated output signal has pulse width generally proportional to the control voltage and carries energy from a source of energy.  The pulse width modulated output signal energizes the coil thereby enabling the coil to generate a force generally proportional to the average current carried by the pulse width modulated output signal.

Abstract: An electrode of solid polymer electrolyte fuel cells is produced by a step of preparing a mixed liquid containing an organic solvent, a noble metal catalyst-supporting carbon powder and a colloid of a solid polymer electrolyte having a particle size of 1 nm or more and less than 400 nm, said colloid being adsorbed to the carbon powder and a step of forming an electrode by coating said mixed liquid on one side of a gas-diffusible layer.          According to the present invention, the solid polymer electrolyte is surely adsorbed to the surface of the catalyst and thus a wide reaction area can be secured.          Furthermore, thickness of the solid polymer electrolyte layer can be controlled to one in which hydrogen and oxygen can be easily diffused.

Abstract: A highly reliable early warning system is disclosed. The warning system provides immediate detection of railway activity and early warning of dangerous railway conditions to train crews and to Rail Traffic Control offices. The warning system has acoustic sensors coupled to one of the rails of a railway for detecting sound or vibration transmitted from physical events. The detected acoustic signals are analyzed by a computer sound recognition system to ascertain the nature of the event causing the signal. If a suspect condition is identified or an unrecognized high energy acoustic signature is detected, an alarm is generated. The alarm signal may be transmitted over any communication system to the Rail Traffic Control office and to the trains traveling toward the suspect track location. The system can also detect railway rolling stock problems such as flat spots on wheels or derailed cars. When desired, the alarm may employ wireless transmissions to stop the trains remotely. When more than one acoustic sensor detects the same event, the exact location can be determined. Any physical events that are detected may be stored in a sound file. These may be catalogued as to location, time and suspected event for retrieval and analysis later.

Title: Automatic answering pick-up device
Inventor: WISE MICHAEL T
IPC: H04M1/72502
Filed: 1998-02-09
Granted: 2002-09-24
Abstract: A cordless telephone headset and remotely controlled telephone handset pick-up device for use in conjunction with an existing corded telephone set. A  mechanical lift arm of the pick-up device, driven by an electric motor with a slip clutch, lifts the handset away from the corded telephone cradle, placing the telephone handset in an off-hook position. The handset is lowered back onto the cradle by the mechanical lift arm, returning the telephone set to an on-hook position. The mechanical lift arm is activated and deactivated in response to a radio signal indicative of the lowering and raising of the microphone boom of the cordless headset. The slip clutch provides sufficient force to gently and reliably raise and lower the telephone handset without causing misalignment between the handset and the cradle and without causing damage. As the handset is gently lowered over the hook switch, the motor drives the lift arm downward beyond a point at which the handset is expected to be lowered into the cradle, ensuring that the telephone is reliably placed on-hook, while the slip clutch limits the amount of force that can be applied to the telephone set. The telephone set rests upon a platform coupled to the lift-arm, providing a unitary structure for the telephone set and handset pick-up device which aids in maintaining proper alignment of the handset to the cradle by preventing the lift arm from forcing the pick-up device out of alignment.
