    摘要： Articles of furniture are formed employing at least three members joined together by mortises and tenons of which one is a first member, when an additional member or members are needed, one such is the mirror image of the first member. In all disclosed embodiments, each first member or members has a first mortise which extends from one end margin at least part way towards the opposite end portion and a second mortise extending from the fist side margin towards the opposite side margin, intersecting the first mortise and extending beyond it. Another member has a tenon, for each first member extending part way along each side margin and is dimensioned to enable it to be entered in a first mortise and slid in one direction towards the opposite end portion of the first member into a position in which the second mortise thereof is unblocked and in the opposite direction into a position blocking the second mortise. An additional member has a tenon for each second mortise and can be slid therein with the another member in its first position and held therein when that member is in its second position, a mortise and tenon that connects said another and additional members. At least one of the mortise and tenon connections is a self-locking connection.

    摘要： A wireless communication receiver is disclosed that operates in a test mode to determine image correction information that is used to suppress undesired image signals when the receiver switches to a normal operational mode. In one embodiment, the receiver includes a frequency synthesizer coupled by a quadrature divider to an in-phase (I) mixer and a quadrature mixer. The mixers are coupled by respective analog to digital converters (ADCs) to respective I and Q channel inputs of a digital signal processor (DSP). In the test mode, a test tone is provided to the mixer inputs. The test tone is divided down further and provided to clock the frequency synthesizer, the ADCs and the DSP. This configuration locks together the mixers, frequency synthesizer, ADCs and DSP ratiometrically in frequency during the test mode while image correction information is being determined. When the receiver switches to a normal operating mode, the frequency synthesizer, ADCs and DSP are clocked by a main clock signal instead of the divided down test tone, and the test tone is removed from the mixers.
