Filed:

Oct 31, 2008

Appl. No.:

12/263112

Inventors:

Ikuroh Ichitsubo - Sagamihara, JP
Brian Michael Wang - Palo Alto CA, US

Assignee:

Micro Mobio Corporation - Palo Alto CA

International Classification:

H03G 3/20

US Classification:

330129, 330133, 330279

Abstract:

A broad-band linear amplifier circuit includes a driver amplifier to produce a first amplified radio frequency (RF) signal in a first single RF band in response to a first input RF signal and to produce a second amplified RF signal in a second single RF band in response to a second input RF signal. The first single RF band and the second single RF band reside in a broad band that has a bandwidth more than two times a bandwidth of the first single RF band or the second single RF band. A sensing circuit can sense a power, a gain, or a phase of the first output RF signal and the second output RF signal, and to produce a sensing signal. A gain control circuit controls gain variation of the driver amplifier in response to the sensing signal.

International Classification:

H03F 3/191
H03G 3/20

US Classification:

330302, 330136

Abstract:

A radio frequency (RF) amplifier circuit includes a first impedance matching circuit configured to receive an input RF signal, a control circuit configured to produce a band control signal according to the frequency of the input RF signal, an RF amplifier having its input connected to the first impedance matching circuit. The RF amplifier can produce an amplified RF signal in response to the input RF signal. A second impedance matching circuit can receive the amplified RF signal from the RF amplifier. At least one of the first impedance matching circuit and the second impedance matching circuit has an impedance that is adjustable by the band control signal. A multi-band filter can switch the amplified RF signal from the second impedance matching circuit to one of selectable narrow-band filters in response to the band control signal.

International Classification:

H04B 7/00

US Classification:

455 412

Abstract:

A vehicle wireless hub includes a vehicle power connector that can draw power from a vehicle battery on a vehicle, a first wireless transmission circuit that can send or receive data with base stations in a long-range wireless network, a second wireless transmission circuit that can provide a short-range wireless network and to transfer data to and from electronic devices, and a network processor that can process data in the first wireless transmission circuit and the second wireless transmission circuit. The vehicle power connector can supply power to the first wireless transmission circuit, the second wireless transmission circuit, and the network processor.

International Classification:

A61B 10/00
G01N 33/543

Abstract:

The invention relates to a respiratory secretion sample collection device that includes a collection reservoir for directly receiving a sample of a respiratory secretion, a displacement member for insertion into the collection reservoir and displacing the sample within the collection reservoir, a container of a diluent for fluid communication with the sample for mixing the diluent with the sample, and an outlet for discharging the mixture of the diluent and the sample to an assay device. In embodiments, the precise volumes of the sample and the diluent are effectively mixed to enable the conduct of assays for which the relative concentration of diluent and sample is critical.
