  • Patent number: 6661017
    Abstract: The present invention provides improved ion implantation systems and methods in which a high voltage probe is utilized in an ion implantation system to directly measure energy of an ion beam incident on a substrate. More particularly, an exemplary ion implantation system can include an ion source maintained at a high electric potential that generates ions, and a plurality of extraction electrodes that can accelerate the ions to a desired energy. The system further includes an end-station, maintained at ground electric potential, in which a wafer holding for positioning a wafer in the path of an ion beam is disposed. The ion implantation system is further characterized by a high energy probe disposed between a high voltage terminus of the ion source and ground for directly measuring the energy of the ions.

  • Publication number: 20030221626
    Abstract: The present invention provides a rotating shaft that can extend between two regions having different ambient pressures. The rotating shaft can include a rotatable hollow outer shell that is coupled to a proximal portion of an inner shaft with a limited number of contact points. A plurality of thermal breaks disposed between the inner shaft and the hollow outer shell impede heat transfer between these two components. A rotary seal coupled to the distal portion of the inner shaft preserves the pressure differential between the two regions. Further, a heat sink removes heat transferred to the seal to ensure that the temperature of the seal remains within a range suitable for its operation. The rotating shaft of the invention can be utilized, for example, in an ion implantation system by the coupling of the outer shell to a wafer holder to position and orient a wafer in a path of an ion beam.

  • Publication number: 20030222227
    Abstract: The present invention provides a beam stop for use in an ion implantation system that includes a base formed of a thermally conductive material, and a heat transfer layer formed of a semi-elastic material that is disposed on a surface of the base. The beam stop further includes one or more tiles, each formed of a thermally conductive refractory material, that are disposed on the semi-elastic layer so as to face an ion beam in the implantation system. The heat transfer layer transfers heat generated in the tile in response to ion beam impact to the base. The base in turn can be coupled to a heat sink to remove heat from the base. The thickness and the thermal conductivity of the base, and those of the heat transfer layer and the tile are chosen so as to ensure uniform expansion of the base and the tile when the beam stop is heated by ion beam impact.

  • Patent number: 6646845
    Abstract: A battery protection system for a battery having a switching mechanism positioned intermediate to the positive terminal and an electrical load of the battery. A controller manipulates the switching mechanism between an open position and a closed position, the closed position connects the electrical load to the battery and the open position disconnects the electrical load from the battery. The battery protection system utilizes a battery state-of-charge detection system, which instructs the controller to open the switching mechanism when the detection system detects a battery state-of-charge that is lower than a threshold value. The battery protection system is also equipped with a vehicle status detection system, which instructs the controller to close the switching mechanism when a vehicle startup condition is detected by the vehicle status detection system.

  • Publication number: 20030179042
    Abstract: Phase shifting network (110) predistorts the input to non-linear amplifier (114) to counteract AM-PM distortion. The input signal is sampled at (116) and its amplitude is detected at (118). The amplitude signal is then used to index a lookup table (122) which contains corresponding data for controlling the phase shifting network (110). The input signal may be digital and the phase shifting process may be implemented in the digital domain.

  • Publication number: 20030176964
    Abstract: Method, control system and computer-readable medium are respectively provided for determining angular crankshaft position prior to a cranking event of an internal combustion engine. Upon issuance of an engine shutdown command, the method allows determining an initial crankshaft position based on a crankshaft position sensor. The method further allows providing a rulebase for relating angular travel of a rotor in an accessory device to crankshaft angular travel. Angular travel of the rotor in the accessory device is sensed since issuance of the engine shutdown command until the engine reaches a resting position. The rulebase is accessed to relate the value of the angular travel of the rotor in the accessory device to crankshaft angular travel and provide an incremental crankshaft angular travel relative to the initial crankshaft position at engine shutdown.

  • Patent number: 6603848
    Abstract: Disclosed is a system and technique for obtaining calling party information where existing “caller-id” techniques do not provide calling party information. Described is a service for a subscriber of a communication medium service for handling incoming calls when the subscriber is connected to the Internet. The techniques give a calling party a chance to provide information to the called party in the form of a voice recording in described circumstances, such as where caller identification information is unavailable if there is an unlisted phone number of a calling party.

  • Publication number: 20030132802
    Abstract: The pre-distorter controller determines at (210) if the residual distortion in the amplifier output is above a threshold. If so, the phase and amplitude of a pre-distortion signal combined with the amplifier input signal are adjusted sequentially to reduce the residual distortion below the threshold. When the residual distortion falls below the threshold, step (214) determines if the residual distortion is below a second, smaller, threshold. If not, step (218) makes small adjustments to the phase and amplitude of the pre-distortion signal sequentially and the residual distortion is again tested at (214) to determine if it is now below the second threshold. If it is, then further adjustments are not made unless the residual distortion level moves above the second threshold. The control process can also be used with a feed forward lineariser to minimise output distortion (FIG. 5) or unwanted input signal components in the signal led forward (FIG. 6).

  • Patent number: 6542460
    Abstract: In a multi-directional orthogonal frequency division modulation (OFDM) communication system, for example, on a digital subscriber line, an uplink channel is provided by a first group of the OFDM sub-channels (sub-carriers), and a downlink channel is provided by a second group of the OFDM sub-channels (sub-carriers). In one aspect, communication efficiency is improved by controlling the relative number of sub-channels allocated to each group, and hence controlling the capacity of the channels dynamically. Preferably, the relative capacities are controlled in response to demand for channel capacity. In another aspect, the orthogonality of the sub-carriers generated by different transmitters is improved by providing a frequency and/or time synchronising signal for providing reference frequency and timing.

  • Patent number: 6523063
    Abstract: A method and system is described that can be used to reliably, efficiently, and securely transmit information in a communications network. The information can be static or dynamic content. A server is configured with logic to encode and decode a link identifier into, safe character sets that are recognizable to many known web browsers. A redirect process is used to limit the amount of communication with the database. This means that the load and the cost of system operation can be reduced.

  • Patent number: 6507865
    Abstract: A method and system are described that can be used to support content collaboration among a group of participants connected to a network. A participant creates an electronic form specifying the content and a list of network addresses corresponding to other participants in the content collaboration. A server receives the form and includes resources for delivering an electronic mail message associated with an electronic medium associated with the content collaboration. When the participant opens the message, the electronic medium is produced by the server that includes static and dynamic regions. The participant can modify or change the content. The dynamic regions are asynchronously updated in the server and indicate the current content of the electronic medium that can be accessed by other participants. The content may be binary or textual.
