摘要： A communication device may include one or more circuits in an integrated transmitter and receiver that includes a transmit path and a receive path. The transmit path may include an I processing baseband transmit path and a Q processing baseband transmit path. The receive path may include an I processing baseband receive path and a Q processing baseband receive path. The one or more circuits may enable sharing a first common filter by the I processing baseband transmit path and the I processing baseband receive path. The one or more circuits may also enable sharing a second common filter by the Q processing baseband transmit path and the Q processing baseband receive path. The first common filter and the second common filter are independently programmable to adjust a phase and/or a gain of the said first common filter, and/or a phase and/or a gain of the second common filter.

摘要： Aspects for measuring IQ path mismatch in signal modulation are described. The aspects include estimating a transmitter IQ mismatch in a form of gain and phase response for transmitter I and Q paths sharing a receiver path, and estimating a receiver IQ mismatch in a form of gain and phase response for receiver I and Q paths sharing a signal source. Further included is compensating for the difference of the transmitter and receiver I and Q paths using a digital FIR filter. Iterative estimation is utilized for filter tap parameters during the compensating.

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.
摘要翻译：一种用于具有至少两种模式的相机中的模式选择装置，即连续拍摄模式和单次拍摄模式。在连续拍摄模式下，只要按下曝光释放按钮，照相机即可连续拍摄照片。在单次拍摄模式下，无论播放按钮持续按下多长时间，相机都可拍摄单张照片。所选模式显示在显示屏上。当后盖打开时，当后盖关闭时，当胶片重新卷绕时，或当胶片进行预备卷绕时，相机返回到单张图像拍摄模式，使得相机不会不经意地留在连续拍摄模式中。
