Abstract: A method and system for collision avoidance that goes beyond automatic steering and braking. A trained artificial intelligence (AI)/machine learning (ML) system is used to detect an impending impact event that exceeds a predetermined severity threshold based on received sensor and vehicle operational data. Upon detecting such an impending impact event, vehicle systems are deployed to avoid or lessen the severity of the impending impact event. These vehicle systems include automatic steering and braking, and automatic tire flattening and vehicle anchor deployment which are intended to stop or slow the vehicle before impact.

Abstract: The present invention relates to a solid oral immediate release dosage form of a pharmaceutically active compound, N-[(1,2,3,4-tetrahydro-5-methyl-8-(4-methylpiperazin-1-yl)-2-naphthyl]-4-morpholinobenzamide, in the form of the free base or pharmaceutically acceptable salts thereof. The invention further relates to processes for preparing said dosage form, the use of said dosage form and a method of prevention and/or treatment of CNS disorders and related medical disturbances using said dosage form.

Abstract: The present invention reduces automatic gain control (AGC) transients using first and second AGC processing branches to receive a signal. A gain is selectively adjusted (if desired) in the one of the AGC processing branches during a first time period. However, a gain is not adjusted in the other AGC processing branch during that first time period. The signals generated by the first and second AGC processing branches are then diversity processed to generate a received signal. The diversity processing effectively reduces the effect of any AGC transient.

Abstract: A method and apparatus for maximizing the signal-to-noise ratio of an output signal from a digital-to-analog converter. In a multicarrier transmitter the power of a plurality of modulated digital data streams are individually adjusted so that the peak power of the sum of the signals of the modulated data streams is equal to a full scale level of a digital-to-analog converter. The power adjusted signals are upconverted to their respective carrier frequencies and combined into a single digital data stream by an adder. The single digital data stream is converted into an analog data stream by the digital-to-analog converter. The power of the analog data stream is adjusted so that the power of each carrier frequency is at a level which provides a corresponding mobile station with a signal of acceptable quality.

Abstract: A digital-to-analog circuit arrangement that can be used, for example, in radio transmitters, includes a Digital-to-Analog Converter (DAC) whose output is connected directly to a mixer. A periodic signal is also provided to the mixer. The frequency of the periodic signal provided to the mixer, is an integer multiple of half the update rate frequency of the DAC. In an embodiment of the invention, the frequency of the periodic signal provided to the mixer, is half the update rate frequency of the DAC. An intermediate frequency (IF) filter can be provided. downstream of the mixer.

Abstract: The present invention reduces the peak-to-average power ratio (PAR) of a signal while at the same time providing improved signal-to-noise-and-distortion and increased dynamic range. In the context of a transmitter, the PAR of an input signal is reduced so that one or more elements of a transmitter can be operated with increased dynamic range. However, the initial PAR is restored before the signal is transmitted thereby removing distortion generated as the result of the PAR reduction. The initial PAR is reduced in the digital domain, converted into the analog domain, and then restored in the analog domain.

Abstract: A digital-to-analog signal conversion method and apparatus provide increased dynamic range. An input signal is mapped to plural digital-to-analog converters. Outputs from two or more of the digital-to-analog converters are combined to generate an output signal having a greater signal-to-noise-and-distortion ratio than would be achieved with a single digital-to-analog converter. In a preferred example embodiment, the output signals are combined without including a quantization noise associated with each of the digital-to-analog converters. Indeed, the combined signal includes the quantization noise associated with only one of the digital-to-analog converters.
