Abstract: An amplifier (1) used with a pulse width modulated signal which improves the efficiency of a low level input signal comprises two or more switching devices (7, 9) with common source/drain or emitter/collector connections. The gates or the bases of the devices are independently driven to optimize the efficiency of the various Rds (on) resistance values of the transistors (61, 63, 65, 89, 91, 93) used in the devices. The amplifier is operated so that during the highest output levels, select switching devices (61, 63, 65) are utilized to reduce in series resistance with the load (13). As output power decreases, devices (89, 91, 93) with higher Rds (on) resistance values are activated by a control signal which greatly improves DC to DC conversion efficiency with improved output voltage resolution, dynamic range and reduced electromagnetic interference potential.

Abstract: A digitally modulated signal is conditioned, such as to facilitate amplification. The digitally modulated signal is derived from an information signal (110, 115) which is mapped (120) onto a symbol constellation to generate a sequence of channel symbols (125). The sequence of channel symbols (125) is processed (410) to provide a conditioned signal (415) having a signal envelope that avoids signal envelope magnitudes below a threshold value (500). From a signal envelope representing the sequence of channel symbols, symbol interval minimum values are determined as the signal envelope transitions through successive channel symbols of the sequence (510). The conditioned signal (415) is represented by localized adjustment of the signal envelope, such as the insertion of an adjustment pulse, to increase a particular symbol interval minimum value, when that value is below the threshold value (520, 530, 540, 545, 555).

Abstract: A battery package (100) includes a transparent window (108) which communicates information about the battery to a battery-powered device such as a portable radio (200). Information about the battery (100) is communicated through the window (108) by a series of light pulses, and is received by a light sensor (340) in the radio. The information is processed by the radio microprocessor (344) and the status of the battery (100) is displayed on the radio display (346). The window (108) is gas permeable and water impermeable, serves as a vent for the battery housing (110) and also as an optical data transmission window.

Abstract: A mobile subscriber unit (102) transmits a signal including vocoder voices frames to a base unit (104) within a communication system (100). The base unit (104) repeats the signal including error information from the voice frames to one or more final recipient unit(s). The originating subscriber unit (102) listens to these error mitigated repeated frames and compares the received signal having error information to voice frame conditions, such as calculated, delayed and muted signal patterns. Based on the comparison, the subscriber unit (102) adjusts its power accordingly.

Abstract: Pulsewidth-modulated amplifier (100) includes a controller (102) which provides for a set of compensated signals (114, 158 and 160). The compensated signals are used for driving a speaker (136). Controller (100) includes a storage area for storing distortion characteristics for the amplifier for a predetermined operational frequency range. The compensated drive signals (114, 158 and 160) help compensate for the electrical non-linear distortions that occur in amplifier (100) and thereby help reduce the output distortion of amplifier (100).

Abstract: A decoder circuit which employs digital sampling and correlation apparatus to detect the presence of a received tone signal exhibiting a predetermined frequency. Samples of received tone signals are taken and, in effect, multiplied by a substantially rectangualr observation window which includes a bite interval of selected duration and location therein. A correlator correlates the windowed samples to detect samples corresponding to the predetermined frequency (main lobe frequency). A significant decrease in undesired side lobe response is thus achieved.
