Abstract: A technique is disclosed that enables both an IEEE 802.11 transceiver and a Bluetooth transceiver to be employed in a single wireless telecommunication station (e.g., a device supporting a wireless telephone, personal digital assistant, etc.) without interfering on each other. In particular, the illustrative embodiment enables standard “off-the-shelf” IEEE 802.11 and Bluetooth transceivers to work in a coordinated fashion in a single telecommunications terminal. In the illustrative embodiment, an IEEE 802.11 transceiver that uses a shared-communications channel notifies a Bluetooth transceiver that a transmit opportunity exists and that the Bluetooth transceiver has permission to use the shared-communications channel. The technique disclosed is also applicable to communications protocols other than IEEE 802.11 and Bluetooth.

Abstract: A technique is disclosed involves a station (e.g., an IEEE 802.11 station, etc.) requesting that one or more frames be transmitted from an access point to the station. The station might have been in power save mode during Bluetooth operation for the purpose of causing the access point to queue frames that are intended for the station. The station making the request is collocated with the Bluetooth station or is, in fact, a single station that supports two protocols (i.e., has two parts), and is able to determine the regular timing of the Bluetooth synchronous connected oriented (SCO) packet transmissions. The requests to the access point for IEEE 802.11 frames are timed to cause the access point response frames to fall between the Bluetooth messages, thus managing potential interference.

Abstract: This invention provides a system and method for establishing proper quantities of components in the initial mixture to be used in the fabrication of a porous ceramic substrate. The components typically consist of a solvent, a bulk fiber such as mullite, an organic binder for use in extrusion of the green substrate, a glass/clay bonding phase that bonds the fibers upon high-temperature curing and a pore former that defines gaps between the particles and is vaporized out of the substrate during curing. By identifying the controllable factors related to each of the components, and adjusting the factors to vary the resulting strength and porosity of the cured substrate, an optimized strength and porosity performance can be achieved. The controlling factors for each component include its relative weight percent in the mixture. The fiber component is also controlled via fiber diameter, diameter uniformity, and fiber length-to-diameter aspect ratio.

Abstract: A method and apparatus are disclosed for improving vehicle tracking and remote control. A wireless telecommunications system infrastructure receives a unique vehicle identifier via a shared-communications channel from a vehicle being tracked, as well as location information for that vehicle. The location information is derived from Global Positioning System signals or from the address of the local infrastructure currently in contact with the vehicle, or both. The same shared-communications channel is used to convey control messages to the vehicle, wherein the messages are mapped into control signals that can disable the vehicle's engine or control some other system that is part of the vehicle.

Abstract: A novel implementation of a partitioned Medium Access Control (MAC) is disclosed. The illustrative embodiment employs a shared bus that typically is already present in a wireless terminal for communication between an Upper MAC and a Lower MAC. The partitioned MAC implementation therefore does not require any additional communication means between the Upper MAC and Lower MAC, resulting in a lower-cost system. In addition, the Upper MAC and Lower MAC pass native data structures by reference over the shared bus, thereby eliminating the need for drivers to coordinate communication via interrupts, handshaking, etc. The partitioned MAC implementation results in a cost-effective distributed architecture in which the Upper MAC resides in the terminal's host processor and the Lower MAC resides in the terminal's wireless station.

Abstract: An apparatus for adjusting the transmission bit rate and fragmentation threshold of a wireless station in response to transmission errors is disclosed. In particular, the illustrative embodiment of the present invention is based on a wireless station that employs both an IEEE 802.11 radio and a Bluetooth radio, and determines whether transmission errors of the IEEE 802.11 radio are due to fading, or interference from the Bluetooth radio. It will be clear to those skilled in the art how to make and use alternative embodiments of the present invention for protocols other than IEEE 802.11 and Bluetooth, as well as stations that employ wireline or non-RF-wireless transceivers.

Abstract: A linear compressor has a hollow piston with crown and sidewall. The piston reciprocates in a cylinder. A piston rod connects the piston to a spring. A connection between the piston rod and the piston transmits axial forces directly to the piston crown. The connection transmits lateral forces to the piston at an axial location away from the piston crown. The connection allows rotational flexibility between the piston and the piston rod transverse to and uniformly around the piston reciprocation axis. Other improvements in or relating to linear compressors are disclosed and claimed.
