摘要： A method for compensating for range gate slide with respect to received returns within a radar altimeter is described. The method includes adjusting the amount of overlap between a range gate pulse and a radar return signal until an altitude output by the radar altimeter is within a desired tolerance, and incrementally increasing an amount of attenuation within the receiver circuit of the radar altimeter until the radar altimeter breaks track with the radar return signal. the method also includes recording a signal strength and altitude output at each increment of attenuation, determining an altitude error for each altitude output, and fitting the signal strength data against the altitude error using a plurality of variable length line segments.

摘要： A delta-sigma modulator is provided with a multi-stage shift register coupled to receive as its input the output from a quantizer including an analog integrator. The serial digital output signal train from the shift register is fed back to the input of the integrator and because of the frequency division which takes place, for a given high clock rate, an operational amplifier with a lower gain/bandwidth product may be employed. The invention also includes a signal processor coupled to the output of the delta sigma modulator and which is arranged to provide an adaptive window based, decimation cycle whose exact timing is data dependent. The adaptive windowing process implemented in a microprocessor-based signal processor allows the first occurrence of a proper polarity state transition occurring during a window period to become the termination point of the computation cycle rather than providing a fixed time interval. By doing so, the effective resolution can be increased by an order of magnitude for a predetermined duty cycle.
摘要翻译： Δ-Σ调制器设置有多级移位寄存器，其被耦合以从包括模拟积分器的量化器接收作为其输入的输出。来自移位寄存器的串行数字输出信号串被反馈到积分器的输入，并且由于发生了分频，对于给定的高时钟速率，可以采用具有较低增益/带宽乘积的运算放大器。本发明还包括耦合到Δ-Σ调制器的输出的信号处理器，其被设置为提供基于自适应窗口的抽取周期，其精确时序是数据相关的。在基于微处理器的信号处理器中实现的自适应加窗过程允许在窗口周期期间发生的正确极性状态转换的第一次出现成为计算周期的终止点，而不是提供固定的时间间隔。通过这样做，有效分辨率可以在预定占空比下增加一个数量级。

摘要： A container for a refrigerator in which the container comprises a pan having an access opening, which is covered by a door pivotally mounted to the pan. The pan is slidably mounted within the refrigerator in a conventional manner. The door has opposing fingers extending from the side edges thereof and a hook extending from the top edge thereof. As the pan is slid outwardly from the refrigerator, the fingers abut liner studs extending from the inner liner of the refrigerator to partially rotate the door from a closed position toward an open position. On the continued sliding of the pan, the hook abuts a sloped surface of the liner to continue the rotation of the door completely into the open position.

摘要： A mullion assembly includes a mullion rail and hot gas tube for preventing condensation on the mullion of a refrigerator/freezer. The mullion rail is rollformed of steel and includes complementary channels for retaining refrigerator and freezer liners. One of the channels includes an additional formed portion to accept and positively retain a hot gas tube in surface contact with a rear surface of a front wall of the mullion rail to provide acceptable heat transfer from the tube to the steel along the entire length of the mullion rail.

摘要： A differential-mode signal transmission system includes a circuitboard composed of at least one dielectric board substrate and a pair of spaced apart conductive parallel planar signal transmission lines disposed on one surface of the substrate and extending between a pair of edges thereof for providing pass-through transmission of differential-mode signals from one to the opposite edge of the substrate. Preferably, the circuitboard is composed of at least a pair of dielectric board substrates being disposed in face-to-face layered contact with one another and having at least one pair of the spaced apart conductive parallel planar signal transmission lines disposed between the layered substrates along the inner surfaces thereof. Ground planes are provided on the outer surfaces of the layered substrates for electrically shielding the parallel planar transmission line pair. Connectors in the form of spaced pairs of conductively plated through holes being electrically isolated from the ground planes on substrate outer surfaces are provided through the substrates and electrically connected to the parallel planar transmission lines for facilitating connection of electrical components thereto.
