摘要： A method (100), a device (300), and a radio (500) are described for compensating for modulator frequency drift while allowing for data transmission in a half-duplex frequency modulated communication system. An adjustment is made to a premodulation signal in such a way that when it is passed through a frequency modulator to provide a transmitter excitation signal, frequency drift is corrected. Subsequent to determining a training command, the transmitter excitation signal passes through a switch to a demodulator. The demodulator output is averaged and used in the adjustment.

摘要： Difficulties in obtaining consistent bonds of high quality between side pieces and tubular headers (10), (12) in heat exchangers are avoided in a side piece (42) that extends between the headers (10), (12) and which has circular recesses (48) at each end (44), (46). The recesses (48) define resilient fingers (56), (58) which may separate to receive the ends of the headers (10), (12) and frictionally grasp the same, eliminating the need for fixturing at this location and assuring a strong consistent gripping of the headers (10), (12), by the end piece (42) to assure consistent bonds of high quality.

摘要： A header plate (20) is provided for receiving the flattened tubes (14) of a heat exchanger. The header plate (20) includes a plurality of tube receiving openings (26), with each of the openings being surrounded by a flange or collar (28) that extends from a base wall (24) of the header plate (20) towards the heat exchanger core (12) to surround the exterior cross section of the associated tube (14). Each of the flanges (28) is shaped to conform to the exterior of the associated tube (14), and a blend radius R is provided at the interface between the base wall (24) and the flange (28). The blend radius R has a size that increases from a radius R1 central to the length of a long side wall (30) of the flange (28) to a radius R2 central to the length of a short side wall (32) of the flange (28).

摘要： Wireless communication systems (100, 800) comprise mobile units (118, 802) provided with a directional coupler (206) and circuit (220) for measuring the complex reflectance (phase and magnitude) of antenna (202) of the mobile units (118, 802). The system (100, 800) has, either in the mobile unit (118, 802) or elsewhere, a processor (238, 808) programmed to perform pattern recognition of the near field environments of the mobile units (118, 802) by using the complex reflectance measurements as feature vectors. Information as to the near field environment at the time of wireless connection drops is suitably accumulated and is used in network upgrade planning and/or mobile unit design evaluation. The complex reflectance is alternatively used to discriminate antenna faults. Alternatively, near field environments that tend to degrade wireless communication performance are detected by the mobile unit using the complex reflectance and the mobile unit then alerts the user.
