摘要： A method for calibrating a transceiver includes selecting one of a plurality of available calibration paths on the transceiver to be active. The transceiver includes a transmitter and a receiver. The selected one of the plurality of available calibration paths couples the transmitter to the receiver through a circuit that is external to the transceiver. A calibration signal may be provided to enable calibration of the transceiver via the selected one of the plurality of available calibration paths. The calibration signal may be received after it has passed through the selected one of the plurality of calibration paths. Characteristics of the transceiver may be measured using the received calibration signal.

摘要： The present invention relates to a battery compartment capable of selectively accommodating an integrated battery unit and a plurality of cylindrical batteries. This battery compartment comprises a housing adapted to fit the integrated battery unit and a support member which is pivotably placed about a support portion provided to a side interior wall of the housing between a supporting position substantially perpendicular to the side interior wall to laterally support the plurality of cylindrical batteries and a recessed position along the side interior wall to be recessed from an accommodating space for the integrated battery unit. This support member is always urged toward the supporting position and a loading of the integrated battery unit is carried out in such a manner that the support member is displaced to the recessed position against a resilience of the support member toward the supporting position.

摘要： A mode selecting device for use in a camera having at least two modes, namely, a consecutive picture taking mode and a single picture taking mode. In the consecutive picture taking mode, the camera operates to take pictures consecutively so long as the exposure release button is depressed. In the single picture taking mode, the camera operates to take a single picture no matter how long the release button is continuously depressed. The selected mode is displayed on a display. The camera returns to the single picture taking mode when the back lid is opened, when the back lid is closed, when the film is rewound, or when the film undergoes preliminary winding so that the camera is not inadvertently left in the consecutive picture taking mode.

摘要： A camera film easy loading takeup spool includes a body member rotatable about a longitudinal axis past a film delivery position and a plurality of peripherally spaced pairs of longitudinal jaw members, one of each of which is swingable about a longitudinal axis between film entry opening open and closed positions relative to the respective other jaw member and spring biased to its open position and including a depending follower engaging a circular cam which closes the jaws offset from the film delivery position and permits the spring opening of the jaw proximate the film delivery position. A film perforation engaging tooth or a friction pad is carried by one of each pair of jaws and the inner ends of the jaws delineate an inner passageway of a width equal to about the film thickness. A visual indicator is actuated when any one of the jaw members is open.

摘要： A camera employing an automatic focusing system has a movable objective lens which is automatically moved from an initial position to a properly focused position in accordance with a distance signal indicative of the distance between the camera and a target object to be photographed from a distance measuring element. The automatic focusing system includes a discriminator which discriminates whether the distance measuring element properly produces the distance signal or fails to produce such distance signal. The objective lens is moved only when the distance signal is properly produced or when a substitute signal is forcibly produced from a manual control unit for the substitution of the distance signal.

摘要： A system for correcting an IQ mismatch in a receiver mixer is disclosed and may include one or more circuits that generate an IQ correlation with a training signal having periodic, uncorrelated I and Q signals. The one or more circuits may estimate a gain mismatch based on a power estimate of the periodic, uncorrelated I and Q signals over a unit period. The one or more circuits may estimate a phase mismatch based on the IQ correlation over the unit period, and may apply at least one correction parameter to the receiver mixer. The at least one correction parameter may be based on the gain mismatch estimate and the phase mismatch estimate. The one or more circuits may provide the training signal on a closed RF signal path between a transmitter and the receiver mixer, and may estimate the IQ mismatch iteratively.

摘要： Aspects for measuring receiver mixer IQ mismatch in a transceiver are described. The measuring includes providing a training signal for a receiver mixer, the training signal having periodic, uncorrelated I and Q signals. A phase mismatch in the receiver mixer is determined from IQ correlation over a unit period. A gain mismatch in the receiver mixer is determined from a power estimate of both I and Q signal for the unit period.
