  • Patent number: 7321578
    Abstract: The embodiment of the present invention comprises a device-internal data flow organization coupled with a wireless communications medium access control protocol for a set of WLAN “Multiprotocol Devices”, each containing a 2.4 and 5 GHz frequency band-agile CCK and OFDM modulation capable radio, such that the devices may support simultaneous IEEE 802.11a and 802.11b/g-compliant Access Point functionality. The set includes a “Multiprotocol Access Point” that bridges communications from IEEE 802.11a and/or IEEE 802.11b/g compliant WLAN client devices, and other Multiprotocol Devices, to the wired LAN distribution system. Also included is a “Multiprotocol Repeater” that relays communications from the above client and Multiprotocol devices wirelessly to another Multiprotocol Device. The set also includes a “High Capacity Multiprotocol Repeater” that can relay a higher volume of communications from IEEE 802.11a, b or g devices wirelessly to another Multiprotocol Device.

  • Publication number: 20060122888
    Abstract: In one arrangement, a method for estimating sales of a particular type of item by a first entity through a first channel versus sales of the particular type of item by the first entity through a second channel includes the step of estimating a particular point of time, such as a day or a month, corresponding to when the first entity initially sold the particular type of item through the first channel. The method also includes the step of selecting a second entity which sells the particular type of item. Specifically, each sale of the particular type of item by the second entity may be through the second channel. The method further includes the step of comparing data associated with sales of the particular type of item by the first entity before the occurrence of the particular point time with data associated with sales of the particular type of item by the second entity before the occurrence of the particular point time to determine an adjustment factor.

  • Patent number: 6933896
    Abstract: The present invention is a retractable/extendable diversity antenna that provides the appropriate polarization in a horizontal orientation. The antenna structure is placed within a Type II PCMCIA PC card package and may be extended or retracted with one touch. The antenna structure is large enough to provide for the diversity antenna design and may optionally be housed within a PCMCIA Type II PC Card. At least one spring-loaded mechanism is used to extend the antenna structure beyond the PCMCIA PC Card package and to provide stability while the antenna structure is in the extended position. The diversity antenna configuration may consist of either two miniature, planar antenna modules or two etched printed circuit board contours that are spaced as far apart as possible with a minimum separation of a quarter wave length distance in order to provide mitigation to radio multipath fading effects.

  • Patent number: 6259409
    Abstract: A method and apparatus is disclosed for wireless communication of a computer with a wireless network or a wireless device. In one embodiment of the present invention, a pc card is configured for insertion into a computer pc card slot. Additionally, a sliding assembly is housed within the pc card. This sliding assembly is operable for sliding into a retracted position and a protruded position. When in the retracted position, the sliding assembly is mostly concealed within the pc card. When in the protruded position, the sliding assembly is partly exposed outside of the pc card. Furthermore, an antenna element is fitted inside the sliding assembly. When the sliding assembly is in retracted position, this antenna element enables wireless communication of a computer with a wireless network or a wireless device.

  • Patent number: 6028919
    Abstract: A plurality of distributed POTS filters (DPF) are associated with a respective plurality of POTS communications devices and decouple a POTS channel from a telephone connection, while permitting and not interfering with a second communications channel (e.g., DSL, ADSL, SDSL, RADSL, VADSL, etc.) on the telephone connection that is utilized by a modem, and permit the passage of additional signals, such as caller ID signals, to the plurality POTS communications devices. In architecture, the DPF system includes a plurality of POTS communications devices, such as telephones, and a plurality of the DPFs corresponding respectively with and connecting each of the POTS communications devices to the telephone connection. Each of the DPFs comprise an automatic control mechanism, which includes circuitry configured to allow the passage of additional signals, such as caller ID signals, to the plurality of POTS communications devices and a POTS filter.

  • Patent number: 5677267
    Abstract: A thixotropic thermal insulating fluid includes a heavy hydrocarbon, water and oleophilic clay, wherein said heavy hydrocarbon is present in an amount of between about 75% to about 92% by volume of the fluid, said water is present in an amount of between about 5% to about 15% by volume of the fluid, and said oleophilic clay is present in an amount of between about 3% to about 10% by volume of the fluid. The fluid may be prepared by mixing water in an amount of between about 5% to about 15% by total volume of the fluid with oleophilic clay in an amount of between about 3% to about 10% by total volume of the fluid so as to provide a substantially homogeneous first gel product; and mixing said first gel product with a heavy hydrocarbon in an amount of between about 75% to about 92% by total volume of the fluid under agitation for a time sufficient to provide a second thixotropic gel product.
