  • Patent number: 6304244
    Abstract: A method and system in a computer having a primary video controller for dynamically selecting an alternative video controller present within the computer. Initially, a diagnostic is performed to determine if alternative video controllers are connected to the computer system. A user is thereafter prompted to select an alternative video controller, if at least one alternative video controller is detected. The primary video controller is then temporarily disabled, in response to a selection of an alternative video controller. The alternative video controller is then automatically designated as the primary video controller, in response to the disabling of the primary video controller, such that the alternative video controller may be temporarily utilized as a primary video controller without altering internal computer system hardware settings or power cycling the computer system.

  • Patent number: 6249812
    Abstract: A client on a network is provided with auxiliary low power logic, at the network adaptor, that is always active and simulates network traffic (e.g., Ethernet format) normally sent under control of the main client system processor(s). This logic collects client status information and reports to the network manager, irrespective of the system's CPU power level, information and provides for interaction between the user and the administration or network manager to exercise broader control and perform repair and upgrades which would otherwise require a dialog with the user and/or limit repair and reconfiguration of the client system to off-hours activity. The auxiliary logic also can receive and interpret commands from the network that conform to a predefined format.

  • Patent number: 6237100
    Abstract: A data processing system and method are described for controlling power supplied to the system. The system includes an internal power supply for receiving energy from an external source and supplying the energy to the system. The energy is full system power and is required for the system to be fully operable. The system is initially powered-off such that the energy is not initially supplied to the system. A power-on password is established. The internal power supply supplies the energy to the system only in response to a correct entry of the power-on password, wherein the system is inoperable prior to the correct entry of the power-on password.

  • Patent number: 6208328
    Abstract: A pointing device makes groping manipulation possible with a single finger and comprises a stick, a vector detection mechanism placed away from the stick by a predetermined distance so as to turn around the longitudinal axis of the stick, for outputting a signal corresponding to a force vector of a force applied by the stick when the stick contacts with the mechanism, and a detector for detecting a force applied in the longitudinal direction of the stick. In response to a signal output from the vector detection mechanism, it is judged whether an evaluation value of the force vector satisfies a predetermined condition. When the evaluation value of the force vector satisfies the predetermined condition, execution of a first kind of manipulation according to the evaluation value is instructed. When the evaluation value does not satisfy the predetermined condition, execution of a second kind of manipulation is instructed.

  • Patent number: 6202824
    Abstract: An assembly verification test uses a sliding cart to transport work-in-process units from an assembly facility to a test area. The cart has a generally square frame with multiple vertical and horizontal frame members. The front end of the cart has wheels that engage the floor. The rearward end of the cart has wheels that are vertically offset from the front wheels and ride along a chassis of the test station that is located above the floor. The upper end of the cart has guide rails for slidably receiving work unit trays from assembly and offloading the trays to the test area. The wheels allow the cart to move laterally from side to side along the length of the test area so that the cart may be easily repositioned in front of any of the test slots.

  • Patent number: 6157555
    Abstract: A system and method for adjusting the maximum allowable current limit for each of a plurality of parallel power supplies within an N+1 power supply system in response to dynamic variations in the total supply current capacity of the N+1 power supply system. A plurality of parallel supplies make up the N+1 power supply which provides power to a load. A sensor within each of the parallel power supplies determines an operating status of each of the parallel power supplies. A detector circuit in communication with the sensors translates the operating status determination into a supply current capacity signal. Finally, a current limit adjustment circuit generates a current limit signal in response to the supply current capacity signal, such that the maximum allowable current limit for each parallel power supply is adjusted while maintaining the overall power supply VA limit for the N+1 power supply.

  • Patent number: 6147856
    Abstract: Devices for use in highly integrated radio frequency transceivers utilize micro-electro-mechanical systems, or wobble motors, to form superior switches and to select and vary components that determine different frequencies of operation. Each device has a substrate with concentric rings of electrodes and contacts. A circular rotor is centrally pivoted or wobbled to engage the contacts along its circumferential edge. The rotor may be mechanically or materially modified to create symmetric or asymmetric forms which interact with one or more stationary capacitor electrodes on the substrate. The positioning of the rotor forms in terms of rotation, overlap and separation, relative to the capacitor electrodes, varies the capacitance.

  • Patent number: 6138086
    Abstract: A computer system is described that is capable of transmitting and displaying files containing variable locale selectors, that is, language, territory and coded character set identifiers. The system contains a code that is transmitted as part of the files, and includes information defining the language and the territory, which are alphanumeric variables normally encoded in binary format, and the coded character set, which is normally encoded as a numeric decimal format. The discrete values of known combinations of these codes are listed, preferably in a lookup table, and each known set of coded values is given a unique hexadecimal value. The hexadecimal value is retained with the subject file and used by a user interface adapter to display the information in the file according to the desired set of locale selectors.

  • Patent number: 6119239
    Abstract: An information processing apparatus with which power saving is enabled for the sound function in accordance with the activities of individual peripheral devices that output audio signals. A check is performed to determine whether or not the individual peripheral devices for outputting audio signals are in the muted state, and the mixer circuit is attenuated only when all the devices are in the muted state. The unused state of the sound function of the information processing apparatus is precisely detected, and power consumption can be reduced when the sound function is not in use. In addition, the "power control flag" in the I/O register of the audio controller is monitored, as well as the muted states of the individual peripheral devices. Therefore, even when the system software (e.g.

  • Patent number: 6098171
    Abstract: Provides management tools for a System Owner to assure that a personal computer system is secured against access by an unauthorized user by foreclosing the possibility of circumventing a system's security protection during an adapter ROM scan. If security function, such as that for C2 functionality, is enabled, prior to the adapter ROM Scan for the system, the POST code detects whether or not disabling of the keyboard during adapter ROM Scan is enabled. If enabled, the keyboard is disabled or locked prior to adapter ROM Scan. On some systems, the security function may not be used and, the system does not consider password protection for the adapter utilities. If however, the security functionality of the system is enabled, the POST code will continue to enable the password protection for the adapter ROM Scan. Once the input device, e.g., keyboard, is disabled the adapter ROM scan will begin. Upon completion of the adapter ROM scan, the input device will be enabled and progress will continue through POST.
