A power machine (200) can be configured to operate in one or more startup modes during startup processes (300), including during startup processes (310) for displays (286) or other input devices. Access to power machine functionality, including access only to limited power machine functionality, can be enabled during the startup processes (300) according to permissions (332) of the startup mode.

An audio system receives an audio signal from a digital microphone, which has an analog-digital converter with a controllable sampling rate. In response to a determination that a predetermined trigger phrase is not detected in the decimated audio signal, the sampling rate of the analog-digital converter in the digital microphone is controlled such that the audio signal has a first sample rate. In response to a determination that the predetermined trigger phrase is detected in the decimated signal, the sampling rate of the analog-digital converter in the digital microphone is controlled such that the audio signal has a second sample rate higher than the first sample rate, and the audio signal is applied to a spoof detection circuit, to determine whether the received signal contains live speech or replayed speech.

A memory controller, which manages a memory device, receives a memory command. The memory controller determines whether the memory command is encrypted. Upon determining that the memory command is encrypted, the memory controller performs a decryption function corresponding to the memory command. Conditioned on the performance of the decryption function resulting in a successful decryption of the memory command, the memory controller performs an operation on a memory location corresponding to a memory address included in the memory command.

In a display assistant device, a speaker is mounted in a waveguide structure which is at least partially disposed beneath a display screen. The waveguide structure is mounted in an exterior housing which includes speaker grills distributed on a plurality of surfaces of the exterior housing, permitting sound waves from the speaker to be projected outside the exterior housing. A cover structure is disposed on top of the waveguide structure to conceal the waveguide structure and speaker within the exterior housing. The cover structure has a tilted bottom surface configured to be suspended above the waveguide structure and to be separated by a first space. Sound waves projected from an upper portion of the speaker are reflected by the tilted bottom surface and are guided through the first space to exit the device from a speaker grill portion located on a rear side of the exterior housing.

In one example, an electronic device may include a power source to supply power to a peripheral device, a sensor circuit to monitor a power consumption of the peripheral device, and a controller coupled to the sensor circuit to detect that the power consumption of the peripheral device is greater than a threshold and generate a popup message on a user interface of the electronic device based on the detection. The popup message may include an option. Further, the controller may direct the power source to continue to provide the power to the peripheral device in response to a determination that the option is selected prior to an expiration of a timer.

This application is directed to a display assistant device that acts as a voice-activated user interface device. The display assistant device includes a base, a screen and a speaker. The base is configured for sitting on a surface. The screen has a rear surface and is supported by the base at the rear surface. A bottom edge of the screen is configured to be held above the surface by a predefined height, and the base is substantially hidden behind the screen from a front view of the display assistant device. The speaker is concealed inside the base and configured to project sound substantially towards the front view of the display assistant device.

A method for providing a secured client computer that includes peripheral components. Each peripheral component processes a corresponding peripheral component data of a data type that is not compatible with peripheral component data types processed by a processor of other peripheral components. The processor of each peripheral component codes the corresponding data of the data type for establishing a secured peer-to-peer communication with other peripheral components.
