Abstract: A user device can verify a user's identity to a server while protecting user privacy by not sharing personal data with any other device. To ensure user privacy, the user device performs an enrollment process in which the user performs an action sequence. The user device collects action data from the action sequence and uses the action data locally to generate a set of public/private key pairs (or other representation) from which information about the action sequence cannot be extracted. The public keys, but not the underlying action data, are sent to a server to store. To verify user identity, a user device can repeat the collection of action data and the generation of the key pairs. If the device can prove to the server its possession of the private keys to a sufficient degree, the user's identity can be verified.

Abstract: A head-mounted device may include a housing structure, a display module mounted in the housing structure, and adjustable support structures coupled to the housing structure. The adjustable support structures may include a first portion that rests against a user's forehead and second and third portions that rest against the user's cheeks or temples. In some arrangements, the adjustable support structures include posts with adjustable lengths, telescoping layers of material, inflatable structures, and/or elastomeric materials that expand and retract to accommodate different face shapes and sizes. In some arrangements, the adjustable support structures include a cable located in a flexible member. When pressure is applied to a forehead portion of the flexible member, the cable pulls the temple portions of the flexible member towards each other. In some arrangements, the adjustable support structures include a movable member that pivots about a pivot axis.

Abstract: Location-based swing compensation for touch sensor panels can improve touch sensing performance. Due to differences in impedance characteristics of touch nodes at different locations in a touch sensor panel (due to differences in routing to touch nodes and due to differences in impedance with respect to ground (loading effects) of touch nodes), touch nodes can have non-uniform bandwidth characteristics which can manifest as non-uniform signal and signal-to-noise ratio (SNR) across the touch sensor panel. Additionally, the non-uniform signal can reduce the effectiveness of bootstrapping. Swing compensated stimulation signals can be applied to various touch nodes based on location and/or impedance characteristics of the various touch nodes. For example, the stimulation voltage can be increased for touch nodes with longer and/or thinner routing traces so that the signal at the touch node can be uniform with other touch nodes whose routing may be shorter and/or thicker.

Abstract: An electronic device may be provided with a dielectric cover layer, a dielectric substrate, and a phased antenna array on the dielectric substrate for conveying millimeter wave signals through the dielectric cover layer. The array may include conductive traces mounted against the dielectric layer. The conductive traces may form patch elements or parasitic elements for the phased antenna array. The dielectric layer may have a dielectric constant and a thickness selected to form a quarter wave impedance transformer for the array at a wavelength of operation of the array. The substrate may include fences of conductive vias that laterally surround each of the antennas within the array. When configured in this way, signal attenuation, destructive interference, and surface wave generation associated with the presence of the dielectric layer over the phased antenna array may be minimized.

Abstract: Systems, apparatuses, and methods for performing coherence processing and memory cache processing in parallel are disclosed. A system includes a communication fabric and a plurality of dual-processing pipelines. Each dual-processing pipeline includes a coherence processing pipeline and a memory cache processing pipeline. The communication fabric forwards a transaction to a given dual-processing pipeline, with the communication fabric selecting the given dual-processing pipeline, from the plurality of dual-processing pipelines, based on a hash of the address of the transaction. The given dual-processing pipeline performs a duplicate tag lookup in parallel with a memory cache tag lookup for the transaction. By performing the duplicate tag lookup and the memory cache tag lookup in a parallel fashion rather than in a serial fashion, latency and power consumption are reduced while performance is enhanced.

Abstract: An electronic device such as a speaker device may have a curved housing characterized by a vertical longitudinal axis. A layer of fabric may cover the curved housing. A touch sensor may be used to detect touch input on the layer of fabric. The touch sensor may include capacitive touch sensor electrodes including drive lines and sense lines. In some arrangements, the touch sensor is formed from conductive strands in the layer of fabric. In other arrangements, the touch sensor is formed from conductive traces on a substrate. The substrate may be formed from portions of the curved housing or may be formed from a layer that is separate from the housing. Light-emitting components and/or fabric with different visual characteristics may be used to mark where the touch-sensitive regions of the fabric are located. The touch-sensitive regions may be shaped as media control symbols.

In one embodiment, the physical address space of the non-volatile memory may be a mapping from a second physical address space that is used within the system.

Abstract: Methods and devices for a wireless accessory device (AD) comprising a cellular radio to communicate with a cellular network using the cellular radio. The wireless AD establishes a texting session with a network entity through the cellular network and using the cellular radio. The wireless AD initiates a countdown timer in response to establishing the texting session. The wireless AD determines that a companion device to the wireless AD is reachable by the wireless AD. The wireless AD refrains from pairing with the companion device until the countdown timer expires in response to determining that the companion device is reachable by the wireless device. After expiration of the countdown timer, if the companion device is still reachable by the wireless AD, the wireless AD may pair with the companion device and/or power down its cellular radio.

Abstract: An apparatus of a Narrowband Internet-of-Things (NB-IoT) user equipment (UE) includes processing circuitry. To configure the NB-IoT UE for open loop transmit power control, the processing circuitry is to decode a narrowband system information block (NB-SIB) to obtain a narrowband physical random access channel (NPRACH) resource set and power control information associated with the NPRACH resource set. A random access channel (RACH) preamble is encoded for transmission with or without repetitions to a base station during a RACH procedure and using the NPRACH resource set. The transmission has transmission power based on the power control information. A narrowband uplink resource assignment received during the RACH procedure is decoded. A connection setup completion message is encoded for transmission to the base station using the narrowband uplink resource assignment.

Abstract: Keyboards and other input devices are provided with at least one flexible layer that extends over or under the keycaps. The flexible layer spans interkey spaces and lies between inner and outer keycaps. The flexible layer prevents intrusion of invasive material to the keyboard mechanisms and simplifies the appearance of the keyboard area. Some flexible layers help align keycaps by connecting inner and outer keycaps or by providing a mechanical connection interface for the keycaps. Some membranes used in the flexible layer have a layered or composite construction that increases durability and tear resistance by attaching or infusing a mesh material or other tough material to a less durable, elastic material.

Abstract: A comparator circuit included in a computer system employs an inverter circuit as a high-speed comparison circuit. To allow the inverter circuit to compare an input signal to a particular threshold value, a trip point of the inverter circuit is adjusted to match the threshold value by modifying a voltage level of a power supply node coupled to the inverter. To modify the voltage level of the power supply node, a replica of the inverter circuit is biased to generate a bias signal that corresponds to the trip point of the inverter circuit. A comparator circuit compares the bias signal to the threshold value, and adjusts the voltage level of the power supply node using results of the comparison. An output circuit adjusts an output of the inverter circuit to generate a full-rail output signal.
