Abstract: A computer system, in response to detecting a first input on a rotatable input mechanism, in accordance with a determination that the first input is a first type of input: changes an immersion level associated with display of an extended reality (XR) environment generated by the display generation component to a first immersion level in which display of the XR environment concurrently includes virtual content from an application and a passthrough portion of a physical environment of the computer system. In accordance with a determination that the first input is a second type of input: the computer system performs an operation different from changing the immersion level associated with display of the XR environment.

Abstract: A computer system displays a first application user interface at a first location in a three-dimensional environment. While displaying the first application user interface at the first location in the three-dimensional environment, the computer system detects, at a first time, a first input corresponding to a request to close the first application user interface. In response to detecting the first input corresponding to a request to close the first application user interface: the computer system closes the first application user interface, including ceasing to display the first application user interface in the three-dimensional environment; and, in accordance with a determination that respective criteria are met, the computer system displays a home menu user interface at a respective home menu position that is determined based on the first location of the first application user interface in the three-dimensional environment.

Abstract: A computer system displays a first and second user interface object in a three-dimensional environment. The first and second user interface objects have a first and second spatial relationship to a first and second anchor position corresponding to a location of a user's hand in a physical environment, respectively. While displaying the first and second user interface objects in the three-dimensional environment, the computer system detects movement of the user's hand in the physical environment, corresponding to a translational movement and a rotational movement of the user's hand relative to a viewpoint, and in response, translates the first and second user interface objects relative to the viewpoint in accordance with the translational movement of the user's hand, and rotates the first user interface object relative to the viewpoint in accordance with the rotational movement of the user's hand without rotating the second user interface object.

The use of hydrophobic surface coatings on these inorganic particles have been found to protect and/or minimize the amount of surface degradation over a period of time.

Abstract: A phase shifter using digital counters allows extremely accurate phase shifts. In a parallel circuit arrangement of a number of basic phase shift units, which each includes a dual modulus counter and phase control circuitry for controlling the counter modulus, the outputs of several units are combined in parallel. With the divider ratios of all the dividers of the units consisting of roots of pairwise relatively prime numbers, the total number of phase states is equal to the multiplication of its divider ratios.

Abstract: Discrete phase modulation for modulating the transmit and receive radar signal waveforms in order to control distortion. The signal is modulated by discrete phases which change from pulse-to-pulse. A digital frequency division circuit accurately generates the modulation signals, and allows the discrete phases to be generated with precise accuracy. The discrete phase changes can be a quadratic phase progression for target Doppler and range detection.

Abstract: A phase shifter that employs digital circuitry to achieve arbitrarily fine phase control of reference signals at frequencies extending to the Gigahertz region. The phase shifter includes a cascade of identical phase shift units that provide progressively finer phase control resolution over a full 360 degree range. The phase precision is set by the number of stages used.

Abstract: A precision digital phase shift element for achieving precise phase shift of an input pulse train signal. The output is a pulse train at a frequency equal to the input signal frequency divided by N, and having N equally spaced phase states. The relative phase state of the output signal is reliably controlled by selective deletion of pulses from the input signal pulse train. The selective deletion can be achieved by selectively gating the input pulse train, or by use of a dual modulus frequency divider circuit.

Abstract: The frequencies of N oscillators are summed to provide a signal generator output signal. Because the phase noise power spectral densities of the oscillators add as power, the frequency summed output exhibits a noise degradation over a single oscillator of only 10 log(N). The signal generator is implemented to assure independence of the oscillator noise contributions, with phase locking the oscillators to a common frequency for ease of spurious signal control.

Abstract: A stand for exhibiting and holding articles which includes an elongate and substantially vertical shaft which extends upwardly from a base. One or more article receiving containers are rotatably mounted to the shaft. Each article receiving container includes a plurality of article receiving and holding pockets extending substantially radially outwardly from the shaft, such that the user can rotate an article receiving container, bringing a desired object stored in a distant pocket closer to the user.

Abstract: Unique stretch and chirp waveform formats are described which allow significant simplification of radar signal generation and receive processing hardware. The new formats produce a non-zero intermediate frequency (IF) to facilitate in-phase and quadrature (I/Q) processing but allows the use of a homodyne type of receiver architecture. That architecture greatly simplifies the receiver hardware because the first local oscillator (LO) signal is simply a sample of the transmitter drive signal and no second LO is required. The non-zero IF is achieved by control of the timing and start frequency of the first LO waveform for stretch processing and timing of the transmit signal gating for chirp processing.

Abstract: A wideband frequency synthesized, fault-tolerant microwave signal generator is described, which can generate the spectrally pure transmitter or antenna drive and receiver first local oscillator (LO) signals needed for advanced tactical airborne radar systems. Separate generation of the transmitter drive (TD) and first LO minimizes spurious signal generation over a wide operating band, typically 45% or greater. Extensive fault tolerance is provided without resort to redundant hardware. The sharing of two internal signal generators limits the frequency generation needs to just the operating band for economy of required hardware.

Abstract: A frequency synthesized, microwave signal generator is disclosed that provides multiple channel frequency selection capability with rapid channel change time and low levels of spurious signals and noise. The generator uses a microwave harmonic phase locked loop to lock a microwave VCO to a programmable harmonic of a VHF reference crystal oscillator to provide coarse frequency control in steps equal to that reference frequency. The phase lock loop includes an offset mixer for injecting an offset signal frequency to achieve fine frequency control. A harmonic detection and counting scheme is used to rapidly sweep the harmonic loop and obtain phase lock at the desired harmonic.

Abstract: A system is disclosed for measuring and correcting for waveform modulation errors in a radar system employing FM signals and a digitally controlled waveform generator. The system relies on the assumption that the transmitter and other waveform phase and amplitude error contributions are slowly varying with respect to the radar mode data collection time and that instantaneous pulse-by-pulse correction is not necessary. During a calibration mode, a small portion of the transmitter output is input into the receiver and mixed with the waveform generator signal, with the waveform modulation being removed from the mixer signal, such that the mixer signal is at a constant IF but with phase and amplitude variations that result from the distortions. The radar digital processor measures these distortions, and during normal radar operation predistorts the waveform generator signal with phase distortions in antiphase with the measured distortions to compensate for the measured distortions.
