  • Patent number: 6368261
    Abstract: A desk chair has a sitting component, a headrest component adjoined to the sitting component and rotational relative to the sitting component, and a left armrest component and a right armrest component both adjoined to the sitting component and rotational relative to the sitting component. The sitting component seats a user of the desk chair and includes a reclining mechanism to enable a user to perform stretching and strengthening exercises for the abdomen of the user. The headrest component supports the head of a user of the desk chair and enables the user to perform stretching and strengthening exercises for the neck of the user. The left armrest component and the right armrest component support the arms of the user of the desk chair and enable the user to perform stretching and strengthening exercises for the chest, back, shoulders, arms and/or abdomen of the user. The user can also utilize the reclining mechanism to increase or decrease the range of motion of an exercise for the user.

  • Patent number: 6364050
    Abstract: In an electric power assisted steering system, the output signal from a motor position sensor (9) comprising a number of Hall effect devices (A,B,C) or the like is combined with an index signal from a sensor (108) connected to the steering column shaft (1) or the rack (6) or a yaw sensor or other angular position dependent device to produce an accurate measure of steering angle relative to the straight ahead position. In a preferred arrangement, transitions in the Hall effect sensor output are used to drive a counter (106) which is reset whenever the index signal is produced to ensure it does not drift out over a period of time. Most conveniently, the index signal corresponds to the steering gear straight ahead position.

  • Patent number: 6354396
    Abstract: An electric power assisted steering system is disclosed which comprises a steering shaft connected at one end to the handwheel and at its other end to at least one roadwheel, while an electric motor is connected to the steering a gearbox having a non-integer reduction gear ratio. Two sensors are also provided with one sensing the angular position of the motor rotor and the other sensing the angular position of the steering shaft. The presence of the non-integer gear ratio produces a beat frequency between the output of the two sensors from which an unambiguous measurement of the angular position of the steering shaft over a range of greater than one complete revolution can be made. The sensors may comprise either absolute position sensors or index-type sensors.

  • Patent number: 6350993
    Abstract: A method and a layered heterostructure for forming p-channel field effect transistors is described incorporating a plurality of semiconductor layers on a semiconductor substrate, a composite channel structure of a first epitaxial Ge layer and a second compressively strained SiGe layer having a higher barrier or a deeper confining quantum well and having extremely high hole mobility. The invention overcomes the problem of a limited hole mobility for a p-channel device with only a single compressively strained SiGe channel layer.

  • Publication number: 20020003021
    Abstract: In a process for making prefastened and refastenable garments, a discrete article is transported in a primary direction of movement. The discrete article can define a leading half comprising first fastening components, a trailing half comprising second fastening components releasably engageable with the first fastening components, and an interconnecting region disposed between and interconnecting the leading and trailing halves. The leading half can be temporarily diverted from the primary direction of movement, while continuing to transport the interconnecting region and the trailing half in the primary direction. After reestablishing movement of the leading half in the primary direction, the leading half can contact a contoured surface, such as a contoured plate or roll. The contact can cause the first fastening components to be transversely displaced toward one another, whereupon the first and second fastening components can be engaged.

  • Patent number: 6316309
    Abstract: A densely packed array of vertical semiconductor devices, having pillars, deep trench capacitors, vertical transistors, and methods of making thereof are disclosed. The pillars act as transistor channels, and may be formed utilizing the application of hybrid resist over a block of semiconductor material. Drain doped regions are formed on the top of each pillar. The source doped regions and the plate doped regions are self-aligned and are created by diffusion in the trenches surrounding the pillars. The array has columns of bitlines and rows of wordlines. The capacitors are formed by isolating n+ polysilicon in trenches separating said pillars. The array is suitable for GBit DRAM applications because the deep trench capacitors do not increase array area.

  • Patent number: 6311075
    Abstract: A conventional antenna 114 at a cell site of a sectored cell in a cellular radio communications system has a low angle of coverage in elevation and therefore has low gain for close-in subscriber units (near the cell site). In a sectored cell, a main beam antenna in a first sector generates sidelobes and backlobes which may fall within the close-in area in other sectors. A close-in mobile in one of the other sectors may move into such an out-of-sector lobe and cause unexpected interference to the base station transceiver (BTS) of the first sector. A downward-looking antenna (DIA) 110 supplements the conventional antenna in each sector and has a beam 112 covering the close-in area. The gain of the DLA beam is greater than that of any out-of-sector lobes and so provides a subscriber unit with a higher gain link to the BTS of its own sector than is provided by out-of-sector lobes to the BTS of any other sector.

  • Patent number: 6304765
    Abstract: A foldable communication device (10) with a housing having two portions (11,12) pivotably mounted to each other to allow relative movement therebetween. This relative movement is about an axis (13) and enabled by mounting portion (11) to two mounts (14,15) of portion (12). Device (10) has a transceiver (17) housed in the housing, an alert transducer (18) associated with transceiver (17) to provide an audible alert at a predetermined volume when a communication call for device (10) is received by transceiver (17) and a controller (19) coupled to transducer (18). In response to the relative movement of portions (11,12), controller (19) reduces the volume of the audible alert without the communication call being answered.

  • Patent number: 6290316
    Abstract: A method of printing utilises a print head comprising a plurality of printing elements which may be actuated independently to print on a substrate, and a control means which produces control signals for the printing elements for independently addressing and controlling the printing elements so that the print head may print a desired character, the method comprising analysing the performance of the individual printing elements to determine the printing characteristic of the print head and to produce control data, feeding the control data to the control means which utilises the control data to compensate for variations in the performance of the individual printing elements whereby the control means produces modified control signals for the printing elements so as to adjust the printing characteristic of the print head, wherein the control means compensates for variations in the performance of the printing elements by activating one or more of the printing elements at a different time to others of the printing e

  • Patent number: 6282522
    Abstract: An architecture and system uses a smart card for payment of goods and/or services purchased on-line over the Internet. A client server on a client terminal controls the interaction with a consumer and interfaces to a card reader which accepts the consumer's smart card. A payment server on the Internet includes a computer and terminals that contain security cards to handle the transaction, data store and collection. Also connected over the Internet is a merchant server advertising the goods and/or services offered by a merchant for sale on a web site. The merchant contracts with an acquirer to accept smart card payments for goods and/or services purchased over the Internet. A consumer uses his smart card at the client terminal in order to purchase goods and/or services from the remote merchant server. The Internet provides the routing functionality between the client terminal, merchant server and payment server.
