  • Patent number: 6237675
    Abstract: A method for automatically controlling the temperature of a vehicle seat (14) based on a variety of factors, including vehicle interior temperature, outside temperature, sunload, and user set point. Each of these readings is sent to a controller (30) where they are weighted by a formula to arrive at a target temperature. Based on that target temperature, a seat level is calculated and then transmitted to a heated seat controller (48) to apply the appropriate temperature to the vehicle seats (14).

  • Patent number: 6223045
    Abstract: A method of sending a short message service (SMS) message to a mobile station operating within a Global System for Mobile Communications (GSM) radio telecommunications network which utilizes a satellite air interface link. A paging server is implemented in the network and interfaced with a mobile switching center/visitor location register (MSC/VLR) serving the mobile station. When a SMS service center receives a mobile-terminating SMS message, it sends the message to the paging server. The paging server stores a copy of the message and sends the message from the paging server to the MSC/VLR. The MSC/VLR makes a first attempt to deliver the message to the mobile station via the satellite air interface radio link. If the SMS service center times out before receiving an acknowledgment that the message was delivered, the service center sends the message to the paging server a second time. Upon receipt, the paging server determines whether the message received the second time has already been sent to the MSC/VLR.

  • Patent number: 6187140
    Abstract: A method of increasing the wet strength of a creped sheet, which method involves providing a sheet which includes cellulosic fibers, which sheet has a first side and a second side; applying a low temperature-curing latex adhesive binder composition to the first side of the sheet in a fine, spaced-apart pattern occupying from about 20 to about 50 percent of the surface area of the sheet; adhering the first side of the sheet to a creping surface; and creping the sheet from the creping surface. The binder composition is adapted to adhere the sheet to the creping surface and includes a functional group-containing latex, a functional group-reactive crosslinking agent, and a volatile base. In addition, the creping surface is heated at a temperature no greater than about 100° C.

  • Patent number: 6132278
    Abstract: Diamond microtip field emitters are used in diode and triode vacuum microelectronic devices, sensors and displays. Diamond diode and triode devices having integral anode and grid structures can be fabricated. Ultra-sharp tips are formed on the emitters in a fabrication process in which diamond is deposited into mold cavities in a two-step deposition sequence. During deposition of the diamond, the carbon graphite content is carefully controlled to enhance emission performance. The tips or the emitters are treated by post-fabrication processes to further enhance performance.

  • Patent number: 5671530
    Abstract: A vertical wafer compact flip chip feeder device includes a loading station for providing a loading location where a flip chip wafer having first and second planar surfaces is received such that the first and second planar surfaces are substantially perpendicular to a first plane. The flip chip feeder device further includes a pick-up station for providing a pick-up location where individual flip chips are retrieved from the flip chip wafer. A wafer translating assembly translates the flip chip wafer between the loading and pick-up stations with the first and second planar surfaces of the flip chip wafer remaining substantially perpendicular to the first plane. A chip pick-up assembly retrieves the individual flip chips from the flip chip wafer at the pick-up station and flips the individual flip chips to a flipped position such that first and second planar surfaces of the individual flip chips are substantially parallel with the first plane.

  • Patent number: 5656827
    Abstract: A solid state chemical sensing device is described in which a chemically sensitive electrode, and at least one diamond film are deposited on a conductive or insulating substrate. The device forms a sensing structure in which conduction of current through the device in the presence of a target chemical is dominated by space charged limited current, thereby providing enhanced sensitivity and selectivity.
