Publication number: 20070082677Abstract: In a wireless LAN (WLAN), methods, apparatuses and systems directed to facilitating configuration of a wireless network is provided. According to one implementation of the present invention, sensors are used to collect data associated with locations and other properties of access points of the wireless network. The collected data can then be used to assist in automatically configuring one or more aspects of the wireless network. In some implementations, the collected data can be used to dynamically re-configure the wireless network in real time. According to another implementation of the present invention, location computation mechanisms are used to collect data associated with the location of one or more wireless clients, and the data is used to dynamically adjust one or more radio frequency (RF) coverage maps in real time. The revised RF coverage maps can then be used to re-configure one or more operational parameters of the wireless network.Type: ApplicationFiled: October 11, 2005Publication date: April 12, 2007Applicant: Cisco Technology, Inc.Inventors: Brian Donald Hart, Timothy Olson, James Amos, David Theobold, Bretton Douglas

Publication number: 20060014503Abstract: A system for measuring output power from an antenna. A sensor receives a sample of wireless signals from the antenna and communicates data about the signal back to the transmitter in a manner such that the antenna pattern is undisturbed. An optical coupler, e.g., fiber optic, is used to send data from the sensor to the transmitter. Power for the sensor can be derived parasitically from the wireless signal or can be provided to the sensor optically.Type: ApplicationFiled: February 3, 2005Publication date: January 19, 2006Inventors: David Theobold, James Amos, Edward Wright

Patent number: 6947971Abstract: Methods and apparatus for caching information associated with packets are disclosed. According to one aspect of the present invention, a system for processing a packet includes a controller with a processor and a controller data cache, a bus, a memory interface, and a separate data cache. The memory interface may be accessed by the controller via the bus, and is arranged to be in communication with a substantially external memory. The separate data cache, which is also in communication with the controller via the bus, caches information associated with the packet such that the controller accesses the separate data cache to obtain the information associated with the packet when the controller needs to decide how to process the packet.Type: GrantFiled: May 9, 2002Date of Patent: September 20, 2005Assignee: Cisco Technology, Inc.Inventor: James A.

Patent number: 6934870Abstract: A clock management scheme for an 802.11 MAC on a PCI or Cardbus bus that works in conjunction with industry standardized power mechanisms. The scheme involves enabling and disabling the main clock in coordination with IEEE 802.11 protocols and is compatible with ACPI power management and configuration interface specification. When the main clock is disabled the MAC and supporting hardware can run off either a lower frequency oscillator or the bus clock. The bus clock is automatically used when it is required by accesses by the host to the card.Type: GrantFiled: February 21, 2002Date of Patent: August 23, 2005Assignee: Cisco Technology, Inc.Inventor: James A.

Patent number: 5429367Abstract: A golf trainer has a continuous hoop formed by curved angle iron or PVC extruded circular segments which are interconnected with short angle iron or steel connector segments. The major segments have forward-extending flanges which, when joined together, form one continuous forward edge. A plastic wear strip with a U shape is pressed over the continuous edge of the joined flanges to form a continuous plastic wear strip for guiding the shaft of a golf club. The hoop has removable lugs which extend rearward, joining two anchor adjustments. A base rod has U-shaped feet formed at front and rear ends. A front end which terminates upwardly in a front loop is connected to a lower lug. A rear end of the base rod extends upwardly to a rear loop. A lower adjustment rod has a lower loop which connects to the rear loop. An upper adjustment rod has an upper loop which connects to an upper lug. Sliders connected to an upper end of the lower adjustment rod receive a lower end of the upper adjustment rod.Type: GrantFiled: July 18, 1994Date of Patent: July 4, 1995Inventor: James Amos

Patent number: 4099768Abstract: Seat and back sections of the unit are pivotally interconnected so that they may be placed in selected angular relationships, including coplanar. Links interconnect this sub-assembly to a base frame so that the subassembly can be supported in either of two positions which are spaced horizontally. This arrangement permits a pair of units to be installed on opposite sides of a removable table to function as seats, and then be shifted together, after removal of the table, to eliminate the leg space and form a continuous bed surface when the seat and back sections are in coplanar position. A locking system secures the selected position determined by the links, and also the angular relationship of the seat and back sections.Type: GrantFiled: July 30, 1976Date of Patent: July 11, 1978Inventor: James Amos

Patent number: 4051541Abstract: A method and associated apparatus for efficiently establishing a "self-sustaining" split in a rotating stack of floppy type storage disks in a form suitable for read/write transducing access. The formation of such splits is fully described in U.S. Pat. No. 3,936,800 to McGinnis et al. In the present method a partial split formed at one disk interface position is used as a stable reference for detecting the location of that interface position relative to a target address position. The form of the partial split is not suitable for storage transducing access. However, the partial split forms much more quickly than the self-sustaining split. If the deviation from the target position is zero the partial split is transformed directly into the self-sustaining fully accessible form by controlling internal ventilation pressure between the disks in accordance with said patent 3,936,880. If the deviation is not zero the mechanism forming the partial split (e.g.Type: GrantFiled: December 8, 1975Date of Patent: September 27, 1977Assignee: International Business Machines CorporationInventors: Bernard William McGinnis, James Amos Weidenhammer
