    摘要: A method of processing location information on a mobile device which includes a primary receiver for receiving a primary signal; a diversity receiver for receiving a diversity signal or location information; a diversity combiner which can combine primary and diversity signals to form a combined signal; and a first processing unit for processing the combined signal; the method comprising the steps of: identifying whether the device is in a location mode or a diversity mode; if the device is in location mode, disabling the diversity combiner; passing the output from the primary receiver directly to the first processing unit; and passing location information from the diversity receiver to a location processing unit.

    摘要: A transmitter circuit (200, 400, 510) and method reduces amplitude modulation distortion in an amplifier (210). The transmitter circuit (200, 400, 510) includes a power control error data generator (230), a feedforward predistortion data generator (240), feedforward adder logic (250) and the amplifier (210). The power control error data generator (230) receives amplitude modulation data (252) and an RF coupled output signal (254) and, in response, produces power control error data (256). The feedforward predistortion data generator (240) receives the amplitude modulation data (252) and, in response, produces feedforward predistortion data (258). The feedforward adder logic (250) receives the power control error data (256) and the feedforward predistortion data (258) and, in response, produces power control data (260). The amplifier (210) receives the power control data (260) and an RF input signal (261) and, in response, produces an RF output signal (262), such that the power control data (260) reduces amplitude modulation distortion in the RF output signal (262).

    摘要: A display case for storing food and beverage products that evenly distributes chilled air within the display case that includes a cassette unit and a chassis that has an interior volume that is encapsulated by a front section, a rear section, a base portion and a top portion and two side portions. The chassis has one or more shelves and one or more goal posts mounted therein. The goal posts deliver chilled air to the shelves. The shelves have a bottom surface that has a plurality of impingement holes disposed therein that disperse the chilled air into the interior volume so that the chilled air blankets the top of the food and beverage products on the shelves below. The shelves may incorporate a groove in the bottom surface. Low power consumption LED lighting may be incorporated in the grove to illuminate the product on the shelf below.

    摘要: A multimode fast attack automatic gain control (AGC) circuit (100) includes an analog feedback loop and a digital feedback loop. The analog feedback loop is switched into the amplifier stage (102) by a first switch (126) when dynamic control of the gain attenuation is desired. The digital feedback loop is switched into the amplifier stage when attenuation is to be adjusted periodically, such as between sequentially received time slots in a time division multiple access (TDMA) mode of communication.
