Appl. No.:

12/429362

Inventors:

Frank A. McLoughlin - Leawood KS, US
Xi Li - Olathe KS, US

Assignee:

Garmin International, Inc. - Olathe KS

International Classification:

G05D 1/00

US Classification:

701 11, 701 14, 2441581

Abstract:

An apparatus and method for estimating future pitch and roll angles of an aircraft to compensate for a time delay caused by a flight instrumentation system calculating the aircraft's pitch and roll. The apparatus may output signals to an aircraft autopilot system. The apparatus may comprise various inputs and outputs, at least one compensation module, and at least one addition module. The compensation module may multiply a gain value by the pitch rate of the aircraft and by the roll rate of the aircraft to determine a pitch compensation amount and a roll compensation amount. Then the pitch compensation amount may be added to the pitch of the aircraft, and the roll compensation amount may be added to the roll of the aircraft to solve for a compensated pitch and a compensated roll to send to the autopilot system.

Abstract:

In an embodiment, the present disclosure pertains to a method of treating a disease by induction of activity in cells. Generally, the method includes administering a bis-indole-derived compound to a subject in need thereof. In some embodiments, the method further includes binding, by the bis-indole-derived compound, to at least one of nuclear receptor 4A1 (NR4A1) and nuclear receptor 4A2 (NR4A2). In another embodiment, the present disclosure pertains to a compound for treating a disease by induction of activity in cells. Generally, the compound includes a bis-indole-derived compound. In some embodiments, the bis-indole-derived compound binds to at least one of NR4A1 and NR4A2.

International Classification:

H03G 3/00

US Classification:

330284

Abstract:

A low noise amplifier including a variable gain amplifier stage configured to accept an input signal and to provide a load driving signal; a tunable bandpass filter connected as a load to the variable gain amplifier stage, wherein the bandpass filter includes a cross-coupled transistor pair, and at least one cross-coupled compensation transistor pair biased in a subthreshold region configured to add a transconductance component when the load driving signal is of a magnitude large enough to decreases a transconductance of the cross-coupled transistor pair; and, a controller circuit configured to tune the bandpass filter. The filter can be tuned in respect to the frequency and the quality factor Q.
