  • Patent number: 6021315
    Abstract: A system and method for testing wireless communication devices uses a waveguide designed for operation beyond cutoff for frequencies used by the wireless communication device to be tested. The waveguide has first and second ends with at least an opened first end to permit the easy insertion and removal of the wireless communication device. An antenna located within the waveguide and coupled to an external test system permits wireless communication between the external test system and the wireless communication device when inserted in the waveguide. Radio frequency (RF) signals propagate between the antenna located within the waveguide and the wireless communication device when inserted into the waveguide. The length of the waveguide is designed to provide sufficient attenuation of RF transmissions when measured at the opened end of the waveguide.

  • Patent number: 6019298
    Abstract: A nozzle for producing an ultrahigh-pressure fluid fan jet is shown and described. In a preferred embodiment, the nozzle has an inner surface defined by a conical bore extending from a first end to a second end, thereby creating an entrance orifice and an exit orifice in the first and second ends, respectively. A wedge-shaped notch extends inward from the second end towards the first end to a sufficient depth such that the shape of the exit orifice is defined by the intersection of the conical bore and the wedge-shaped notch. As pressurized fluid passes through the nozzle and out the exit orifice, the shape of the exit orifice causes the pressurized fluid to exit in the form of a fan jet having a substantially oval cross-section. This fan jet may be swept across a surface to be cleaned thereby selectively removing a layer of material from an underlying surface evenly and completely, without damaging the underlying surface. The fan jet may also be used to cut a fibrous or hard material.

  • Patent number: 6018800
    Abstract: A method for ensuring secure delivery of a computer system to a customer. The computer system includes a motherboard with a processor, a read-only memory, and a programmable memory. The method encodes onto the read-only memory an identification number for the computer system. The computer system is sent to the customer via a first delivery channel and the identification number is sent to the customer via a second delivery channel. When the computer system is initially booted after being sent, the computer system prompts for input of the identification number for the computer system. When the computer system receives an identification number that matches the identification number encoded onto the read-only memory, it stores an indication of the match in the programmable memory indicating that the identification number has been verified to be correct so that the computer system operates normally thereafter.

  • Patent number: 6018792
    Abstract: A computer system has a system memory, cache memory, system controller that process memory transactions. The system controller transmits a memory request to the system memory without waiting for the cache memory to be snooped to determine whether the cache memory stores information in an address corresponding to a selected address of the system memory. The system controller may transmit a snoop request to the cache memory concurrently with or after the memory request is transmitted to the system memory. The system controller may have a control switch that uses a first pathway for the memory request and a second pathway for the snoop request so that the snoop and memory requests can be transmitted simultaneously.

  • Patent number: 6018274
    Abstract: The present invention relates to a radio receiver, particularly to a receiver for use in single-frequency applications, such as GPS, and to a frequency generator, which may be used in such a radio receiver, or elsewhere. The frequency generator comprises a tuned circuit connected between the emitter of the transistor and ground, such that a voltage signal at the basic frequency appears on the emitter terminal of the transistor. This arrangement has the advantage that the two frequencies appear on separate ports, and provides a radio receiver including radio receiver circuitry for connection to digital signal processing circuitry, reducing the complexity of the overall circuit. Additionally, there is a radio receiver wherein separate first and second local oscillator signals are generated from the terminal of s single transistor, avoiding the need for cascade multiplication stages, again reducing the size and complexity of the overall circuit.

  • Patent number: 6018255
    Abstract: The row decoder includes a predecoding stage supplied with row addresses and generating predecoding signals; and a final decoding stage, which, on the basis of the predecoding signals, drives the individual rows in the array. The predecoding stage includes a number of predecoding circuits presenting two parallel signal paths: a low-voltage path used in read mode, and a high-voltage path used in programming mode. A CMOS switch separates the two paths, is driven by high voltage via a voltage shifter in programming mode, and, being formed at predecoding level, involves no integration problems.

  • Patent number: 6016272
    Abstract: An analog reading circuit having a current mirror circuit forcing two identical currents into a cell to be read and into a reference cell. An operational amplifier has an inverting input connected to the drain terminal of the cell to be read, a non-inverting input connected to the drain terminal of the reference cell, and an output connected to the gate terminal of the reference cell. The reference cell therefore forms part of a negative feedback loop which maintains the overdrive voltages of the cell to be read and the reference cell constant, irrespective of temperature variations. The reading circuit is also of high precision and has a high reading speed.

  • Patent number: 6014304
    Abstract: The invention relates to a method of and an apparatus for controlling a plurality of mutually communicating actuators, each of the actuators having at least one signal sensor for determining the state of the actuator, with at least one control apparatus generating, in accordance with the state of at least one of the actuators, control signals used for driving controllers of the actuators. In order to avoid overheating of the individual actuators or the control apparatus in case of a large number of actuations by a user, it is provided to determine the temperature of the actuators and the control apparatus cooperating with the actuators and, in case a predetermined temperature threshold value is exceeded in an actuator or the control apparatus, to generate a control signal for non-driving the controllers of the actuators until the excessive temperature detected drops below the temperature threshold value by a defined temperature value.
