Abstract: A communication device (100) and method (700) are disclosed for providing temporary communication features, temporary scheduling features, or combinations thereof associated with temporary membership in a private network (101), such as that associated with a hotel (102), resort (103), or cruise ship (105). An association module (209) can register (701) the communication device (100) with the private network (101) as a temporary member device. A private network information retriever (210) can then retrieve (702) one or both of private network directory information (109) and private network scheduling information (110). An integrator (211) can then integrate this information into an address book application (212) or a calendaring application (215) to provide additional functionality for the communication device (100).

Abstract: Techniques for locating wireless channels usable for transmitting media signals from personal media players that are adequately separated from wireless channels used for other purposes. One technique involves identifying a target channel and at least two additional channels within a certain proximity of the target channel, and evaluating a channel usability algorithm based on characteristics, such as the received signal strengths, of the target channel and the received signal strengths of each of the proximate channels. Based on evaluation of the algorithm, the target channel is deemed either usable or not usable to transmit the media signal. The most desirable available target channel(s) in a particular group or sub-group of wireless channels may also be identified.

Abstract: An interface enables an RF signal, a DC power signal, and a data signal to be conveyed between two devices over a single RF cable. In an exemplary application of this invention, a steerable antenna system is coupled to a wireless adapter for use in a wireless network. The steerable antenna includes a plurality of panels that can be selectively activated in response to the data signal, which also determines a direction in which an RF signal is transmitted or received by a selected panel of the antenna. Low pass filters in each device isolate the DC power supply and the load from the other two signals. High pass filters isolate the radio in the wireless adapter and the antenna array from the DC and data signals. The data signal is preferably encoded into a Manchester format that passes through a bandpass filter provided in each device.

Abstract: An electronically steerable antenna system includes a plurality of panels that are coupled together to form an N-sided polygon. Each panel includes a plurality of microstrip conductor patches forming a phased array antenna. In a first embodiment that includes beam steering, each panel can selectively transmit or receive in a direction that is either perpendicular to the panel, or to the left or right of perpendicular, depending upon relative delay line lengths applied to the left and right antennas. A second embodiment omits the beam steering capability for each panel and simply enables only one of the N different panels to be employed for transmitting or receiving a radiofrequency signal in a direction perpendicular to the panel. PIN diodes are preferably used for selecting the panel that is active, and in the first embodiment, for selecting the delay lines used.

Abstract: A wireless device is coupled to a multi-sector antenna that includes a plurality of different sectors, any of which can be activated to transmit and receive in a desired direction specific to that sector. Optionally, an omnidirectional antenna is included for initially establishing a wireless connection with another wireless device, such as an access point. A parameter indicative of signal quality, such as throughput or received signal strength indication (RSSI) is determined by polling with each antenna sector to establish a prioritized candidate list. If a receive Trigger becomes active in response to a parameter falling below a threshold level, a new candidate sector is selected from the current list based upon a next-best signal quality. The directionality of the multi-sector antenna provides a substantially higher data rate compared to that of the conventional omnidirectional antenna.

Abstract: A wireless access point is equipped with both an omnidirectional antenna and a directable antenna that can be selectively directed to any of a plurality of directional spaces overlapping the network space served by the omnidirectional antenna. The directable antenna is directed to an optimal directional space for a client when the access point is communicating with the client at a high data rate. The access point can intermittently exchange information with other clients using the omnidirectional antenna. The omnidirectional antenna enables broadcast signals to be transmitted to any client in the entire network space, but at a lower data rate. A preferred data rate and an optimal client directional space are re-determined periodically or as necessary based on parameters such as the data rate, signal strength, and rate of success in communicating data.

Abstract: Methods and apparatuses are provided for using a single transmit queue to transmit a plurality of access categories in an IEEE 802.11 system. To use a single transmit queue, conventional frame descriptors that are used to pass data frames between the wireless NIC and the host are modified to include access parameters for the packets that are associated with the frame descriptors. This allows transmission hardware to dynamically change how each packet is transmitted. For example, the contention policies may be implemented on a packet-by-packet basis, even from a single transmit queue. Also, packets of various access categories into appropriate positions within the single transmit queue.

Abstract: A device for dispensing granulated material on a surface. A hopper having a fill opening and a dispenser opening is mounted to a wheeled frame having a control handle. An agitator is mounted in the hopper. A spreader is mounted to the frame below the dispenser opening to propel granulate material falling through the opening towards a baffle mounted to the frame. The baffle deflects the granulated material to the ground. A sweeper mounted to the frame rearwardly of the baffle sweeps granulated material deposited on the ground to ensure even distribution. A power source provides power for the various component parts.

Abstract: A method for automatically reviewing the source code for a system where the source code is generated automatically from a model of the system is provided. In a first step, the model is read in and processed to determine the expected computer code based on the model. Next, the generated source code is read in. The generated source code is compared to the expected source code to determine if the generated source code includes all the elements of the expected source code.

Abstract: In a method of crude oil production where at a well head a mixture of particulates, crude oil and water is produced for storing in a production tank for settlement of the mixture in to the constituent parts for separate extraction from the tank or the mixture is pumped though a pipeline to a remote location, the mixture is transferred from the well head to the production tank or to the pipeline through a transfer duct in which an initial separation of the mixture is caused by heating material in the duct by a surrounding jacket and by running an auger flight with a ribbon flight in the duct which carries the particulate materials along the duct for discharge.

Abstract: A translating bi-directional packet repeater includes a first antenna and a second antenna for receiving a wireless signal, amplifying it, and retransmitting it on a different channel. The channel associated with each of the antennas is separated in frequency sufficiently to ensure good isolation between the wireless signals that are received and then retransmitted. The wireless signal is down converted to an intermediate frequency (IF) that is passed through a band pass filter, and the filtered signal is then up converted and retransmitted on the different channel. A controller responds to a wireless signal on one of the antennas in selecting a path through the bi-directional amplifier and the antennas used to receive and retransmit the signal. The isolation between the received wireless signal and the retransmitted wireless signal is sufficient to avoid interference, and the retransmission takes place almost instantaneously to minimize the delay incurred.
