Abstract: Multiband operation of a single Wi-Fi radio is described. Some examples can include operating a first radio frequency band on the single Wi-Fi radio of an access point. The method can include switching, based on client device traffic patterns, to a second radio frequency band on the single Wi-Fi radio of the access point.

Abstract: To enable a network apparatus to detect L3 roaming users and to take appropriate forwarding actions, L3 knowledge is introduced inside an L2 bridge forwarding table in the network apparatus. As a client moves from a subnet associated with a first network element to a subnet associated with the network apparatus, a determination is made regarding whether the client is roaming by evaluating a source IP address within a L3 packet header within a first frame received at the network apparatus. If, as a result of the evaluating step, it is determined that the client is roaming, the L2 bridge forwarding table is configured to include a source MAC address of the client together with information identifying a destination interface for use in directing client data traffic back towards the subnet associated with the first network element.

Abstract: To enable devices to detect L3 roaming users and to take appropriate forwarding actions, L3 knowledge is introduced inside a bridge in a non-intrusive way. In particular, as a client moves from a subnet associated with a first network element to a subnet associated with a second network element, a determination is made regarding whether the client is roaming. This is done by evaluating a source IP address within a L3 packet header within a first frame received at the second network element. If, as a result of the evaluating step, it is determined that the client is roaming, an L2 bridge forwarding table in the second network element is configured to include a source MAC address of the client together with information identifying at least a destination interface for use in directing client data traffic back towards the subnet associated with the first network element. The first frame is then forwarded.

Abstract: A fast roaming (handoff) service is provided for a WLAN infrastructure. A given mobile station (STA) obtains a pairwise master key (PMK) when it associates with an access point (AP) in the infrastructure. A neighbor graph identifies prospective APs to which the STA may then roam. At initialization, preferably the neighbor graph is fully-connected (i.e., each AP is assumed to be connected to every other AP). The PMK (obtained by the STA initially) is shared proactively with the neighbor APs as indicated in the neighbor graph. Thus, when the STA roams to a neighbor AP, because the PMK is already available, there is no requirement that the STA initiate a real-time request to an authentication server to re-associate to the new AP.

Abstract: A vehicle radio antenna control wherein the extension of the antenna is controlled by the radio on-off switch and the vehicle ignition switch in series, and the retraction of the antenna is controlled by a switch which is actuated in response to the manipulation of a mechanism which protects the vehicle from unauthorized entry, such as a door lock, when either or both ignition switch and radio on-off switch are in the off position.

Abstract: An analog signal of a direct current potential magnitude proportional to the peak combustion pressure of a monitored internal combustion engine cylinder is simultaneously applied to two mutually exclusive comparator circuits, each being arranged to produce a separate respective output signal when the monitored cylinder peak combustion pressure is less than a first predetermined value or greater than a second higher predetermined value. With a signal present upon the output of either comparator circuit, upon the occurrence of a clock signal produced when another selected engine cylinder is later fired, either an ignition spark advance or an ignition spark retard signal is produced as determined by the comparator circuit output signal present. The adjustable ignition spark timing mechanism of an associated ignition distributor is operated to retard the ignition spark in response to an ignition spark retard signal and to advance the ignition spark in response to an ignition spark advance signal.

Abstract: An encoder produces for each cylinder of an internal combustion engine a plurality of crankshaft position digital code signal groups, each being a representation of a respective different crankshaft position in degrees relative to piston top dead center.
