Abstract: Bias circuits and methods for silicon-based amplifier architectures that are tolerant of supply and bias voltage variations, bias current variations, and transistor stack height, and compensate for poor output resistance characteristics. Embodiments include power amplifiers and low-noise amplifiers that utilize a cascode reference circuit to bias the final stages of a cascode amplifier under the control of a closed loop bias control circuit. The closed loop bias control circuit ensures that the current in the cascode reference circuit is approximately equal to a selected multiple of a known current value by adjusting the gate bias voltage to the final stage of the cascode amplifier. The final current through the cascode amplifier is a multiple of the current in the cascode reference circuit, based on a device scaling factor representing the relative sizes of the transistor devices in the cascode amplifier and in the cascode reference circuit.

Abstract: A technique for implementing an untethered access point (UAP) mesh involves enabling AP-local switching at one or more UAPs of the mesh. A system constructed according to the technique may include an untethered access point (UAP), including: a radio; a backhaul service set identifier (SSID) stored in a computer-readable medium; an anchor access point (AAP) selection engine embodied in a computer-readable medium. In operation, the AAP selection engine may use the radio to attempt to associate with the AAP if a beaconed backhaul SSID matches the stored backhaul SSID. A method according to the technique may include beaconing with a backhaul SSID, acting in concert with an upstream switch as an authenticator for a downstream station that responds to the beacon; providing limited local switching functionality for the downstream station.

The second base and the second body of the second mixing bowl are received within the first mixing bowl with the second rim in supporting contact with the first rim of the first mixing bowl.

Abstract: A technique for implementing AP-local dynamic switching involves Layer 2 switching. This may be accomplished by providing data associated with wireless stations to an AP sufficient to enable the AP to determine whether traffic from a particular wireless station should be locally switched. Alternatively, the wireless station may be able to determine whether to locally switch traffic based upon the traffic itself. For example, it may be desirable to AP-locally switch voice traffic to avoid latency, which is particularly detrimental to voice transmissions such as voiceover-IP. Traffic that is not to be switched locally is Layer 2 tunneled upstream.

The blower is configured to deliver process air into the receptacle via the inlet, along the outer side wall to create a process air vortex, and out of the receptacle via the outlet, such that particulate matter is separated from the process air and collects within the receptacle.

Abstract: A laundry appliance includes a first lint filter operable between a use position and a maintenance position, a second lint filter proximate to the first lint filter, a switch operable between a first condition and a second condition, and a blower. Movement of the first lint filter from the use position to the maintenance position prompts the switch to enter the second condition from the first condition. The blower is operable to deliver process air through the first and second lint filters in the first condition of the switch and is configured to activate to deliver process air through the second lint filter based on the switch entering the second condition.
