Abstract: A thermal management system that includes a fan assembly, a heat exchanger, and an insulating box is described. The fan assembly can have two impellers and a housing that includes two scroll portions. An internal portion of the scroll wall can be truncated. A motor housing can be connected to the fan housing via multiple struts. The struts can be oriented angularly with a tangential component and can slope inward to increase the effective inlet area. The heat exchanger can be formed of a fin stack that has a curved body that defines an airflow path that turns radially from the inlet to the exhaust. The heat exchanger can have an inlet that is smaller than the exhaust. The heat exchanger can be connected to one or more heat pipes. The insulating box can have a grid that directs air to certain specific directions.

Abstract: AC inlets that have a low profile, are able to withstand side-to-side and axial forces, and are readily manufactured. An example can provide an AC inlet having a low-profile by providing power and ground prongs where the power and ground prongs are attached to flanges that can extend laterally from a back end of each prong. This lateral distribution of power and ground can reduce a depth of the AC inlet and provide the AC inlet with a low profile.

Abstract: Connector receptacles and device enclosures that can provide proper grounding, improved ventilation, and an aesthetically pleasing appearance. An example can include a device enclosure including an enclosure wall and sleeves for a number of connector receptacles. Each sleeve can electrically contact a shield of a corresponding connector receptacle via a conductive structure, such as a conductive gasket, to provide a good ground path. The sleeves can be narrow at the enclosure wall for improved ventilation and an aesthetically pleasing appearance.

Abstract: In a method of device-to-device communication, a user device initially sends an emergency message repeatedly at a first repeating frequency. When a specified number acknowledgement (ACK) messages are received, the user device sends the emergency message repeatedly at a reduced repeating frequency. The repeating frequency may be further reduced when more ACK messages are received.
Abstract: Audio jacks and device enclosures that provide proper grounding, are readily reworkable, provide improved ventilation, and have an aesthetically pleasing appearance. An example can include a device enclosure including an enclosure wall and a sleeve for an audio jack. The sleeve can connect to ground through various paths. The audio jack housing can be inserted in the sleeve and kept in place using a fastener. This arrangement can allow the audio jack to be readily reworkable. The sleeve can be narrow at the enclosure wall for improved ventilation and an aesthetically pleasing appearance.

Abstract: Support for additional components may be specified in a coding scheme for image data. A layer of a coding scheme that specifies color components may also specify additional components. Characteristics of the components may be specified in the same layer or a different layer of the coding scheme. An encoder or decoder may identify the specified components and determine the respective characteristics to perform encoding and decoding of image data.

Abstract: A power control method for device-to-device communication includes dynamically backing off transmit power value for synchronization signals and discovery messages when the distance between the two devices is less than a pre-determined threshold. The threshold distance may correspond to a distance where the receive power may exceed a pre-determined value. Embodiments may loop the transmit power of synchronization signals between a default transmit power value and backed-off values in consecutive slots of each frame.
Abstract: Sockets that have a simplified design and are readily manufactured, and also provide easy access for users to change cards while allowing the use of thinner device enclosures.
Abstract: An accessory communication control protocol can facilitate faster and more secure transmission of status updates from an accessory to a controller (or network base station). An accessory can register with a controller, where the controller can provide some subscription and key generation information to the accessory. The accessory can detect changes to characteristics of the accessory and generate a broadcast notification that includes updates to the state of the characteristic. The broadcast notification can also include a counter, a device identifier, and a key. According to timing or rules, the accessory can transmit the broadcast notification to the controller without the need to establish a secure session with the controller.
Abstract: Mechanisms that may help to secure connector inserts in place when they are plugged into a connector receptacle on an electronic device. One example may provide a connector receptacle having a friction mechanism to provide friction between a connector insert and a connector receptacle when the connector insert is inserted in the connector receptacle. Other examples may provide a connector receptacle having a locking mechanism to hinder or prevent extraction of a connector insert.

Abstract: A damper arrangement may be used in a camera module that includes a first (e.g., stationary) and a second (e.g., dynamic) component. The second component may hold a lens such that the lens moves together with the second component. The damper arrangement may include an interface member that extends from the first or the second component to at least partially into a viscoelastic material within a volumetric space configured in the first component, the second component, or both. The interface member may include a mounting portion having a thickness and a viscoelastic material section, having a different thickness, that interacts with viscoelastic material to dampen motion of the second component, for example, during operation of a lens actuator to move the second component along an optical axis of the lens. The interface member may be a two-piece interface member, such as a pin soldered into a hole in a plate, for example.

Abstract: In a method of device-to-device communication, efficient power management is provided when a primary device has a low battery level. The primary device can send synchronization signals and discovery messages to secondary devices by looping through a sequence of transmit power values in a sequence of consecutive frames, where the sequence of transmitting values includes a default power value and a reduced power value.
Abstract: A portable electronic device is described in this disclosure. The portable electronic device can take many forms including for example a smart watch, a smart phone, or a tablet computing device. The portable electronic device can include a device housing component; and a display assembly coupled to the device housing component. The display assembly includes a protective cover that shields a display component from damage. The portable electronic device also includes an actuator configured to apply a vibratory input to the display assembly. In some embodiments, the actuator contacts both the device housing component and the protective cover of the display assembly. In some embodiments, the actuator is affixed only to an interior-facing surface of the display component.

Abstract: Connectors having contacts that can be highly corrosion resistant, can conserve precious materials, and can be readily manufactured. Examples can provide connector contacts that are highly corrosion resistant. These contacts can be formed of a precious metal or a precious-metal alloy. The precious-metal alloy can be a high-entropy alloy. To conserve the precious materials, a contact can be formed by a stamping a structure that becomes the contact, instead of stamping the contact from a structure. The structure can be a rod. To conserve the precious materials, only contacts that convey high voltages, such as power supplies, might be formed of the precious materials.

Abstract: Embodiments described herein provide a privacy mechanism to protect user data when transmitting the data to a server that estimates a frequency of such data amongst a set of client devices. One embodiment uses a differential privacy mechanism to enhance a user experience by identifying particular websites that exhibit particular characteristics. In one embodiment, websites that are associated with a high resource consumption are identified. High resource consumption can be identified based on threshold of particular resources such as processor, memory, network bandwidth, and power usage.
