Systems and methods for attaching a virtual input device to a virtual object in a mixed reality (MR) environment are provided. The system includes a memory, a processor communicatively coupled to the memory, and a display device. The display device is configured to display a MR environment provided by at least one application implemented by the processor. The mixed reality environment includes a virtual object corresponding to an application, and a virtual input device. The at least one application docks the virtual input device to the virtual object with an offset relative to the virtual object.

A test and measurement instrument includes an acquisition memory and a processor structured to store a stream of sampled incoming data samples in the acquisition memory. As the memory fills, the instrument automatically decimates either the data samples already stored in the acquisition memory, the incoming data samples, or both. The instrument may also store two copies of the incoming data samples, one at an increased decimation rate. The two copies are tied together with a timestamp or using other methods. The more highly decimated copy may be used to produce a video output of the stored data samples, saving the instrument from generating the video output from the larger sized sample.

A microphone assembly includes a housing including a base, a cover, and a sound port. The microphone assembly further includes an acoustic transducer and an electrical circuit, both of which are disposed in an enclosed volume of the housing. The transducer and electrical circuit work in concert to convert sound waves into a processed digital audio signal. The electrical circuit is configured to process digital data in a series of frames that correspond to a fixed period in time. The electrical circuit is further configured to reduce noise in the resulting signal by varying the current draw required in a randomized or pseudo-randomized fashion between adjacent frames of digital data.

A sampling circuit includes: a first transmission line that transmits an input signal; a second transmission line that transmits a clock signal; and a plurality of sample-hold circuits that are connected to the first and second transmission lines at a constant line distance, wherein the first transmission line transmits the input signal at a first propagation time for each of the line distances, and the second transmission line transmits the clock signal at a second propagation time that is a sum of a preset sampling interval and the first propagation time for each of the line distances.

A touch analog front-end circuit includes a current conveyor and an accumulator. The current conveyor receives a first voltage as an operation voltage, and generates a current signal according to a touch sensing signal received from a touch display panel. The accumulator is coupled to the current conveyor, receives a second voltage as an operation voltage, and generates an accumulating result according to the current signal and a reference voltage. The first voltage is higher than the second voltage.

An analog-to-digital converter (1) includes an S/H circuit (10) that samples and holds an analog input signal in synchronization with a first sampling clock signal (CLK1), a filter circuit (20) that smooths an output signal of the S/H circuit (10), and an ADC circuit (30) that samples an output signal of the filter circuit (20) in synchronization with a second sampling clock signal (CLK2) different from the first sampling clock signal (CLK1), and outputs a digital signal corresponding to an amplitude of the output signal that is sampled.
