Abstract: Embodiments of the present application relate generally to wireless electronics, wireless portable electronics, wireless media presentation devices, audio/video systems, and more specifically to passive or active RF proximity detection of wireless client devices in an environment that may or may not include wireless access points. A wireless client device may be forced, triggered, or configured to broadcast a wireless scan (e.g., an active WiFi scan) that includes data (e.g., packets) that may be discovered by a wireless media device (e.g., received by RF circuitry in the media device) and information from the wireless scan may be used by the wireless media device to detect presence of the wireless client device and/or its user, to establish a wireless data communications link with the wireless client device, to determine proximity of the wireless client device to the wireless media device, and for near field communication (NFC) with the wireless client device.

Abstract: A system, apparatus, or method for enabling an application developer to access the events, data and functionality of a device, such as a mobile phone, without being limited by the API provided by the device manufacturer. In some embodiments, the present invention utilizes a transparent gateway as a proxy that is inserted into the device stack to enable an application developer to access features and functions of the device beyond those exposed by the manufacturer provided API. For example, the transparent gateway may be inserted into the wireless stack of a mobile phone, in between the Bluetooth stack and the device's API. The transparent gateway may be installed in the mobile phone via an over the air provisioning or another suitable method.

Abstract: One or more wearable devices may measure real-time blood pressure in a body using signals from multiple sensors including but not limited to a multi-axis accelerometer, a bioimpedance (BI) sensor, a capacitive touch sensor, an electrocardiography sensor (ECG), a ballistocardiograph sensor (BCG), a photoplethysmogram (PPG), a pulse oximetery sensor, and a phonocardiograph sensor (PCG), for example. Accelerometry data (e.g., from a multi-axis accelerometer or BCG sensor) may be used to derive effects of acceleration (e.g., gravity) on changes in blood pressure (e.g., due to changes in blood volume as measured using BI signals). The accelerometry data may be used to determine a baseline value for BI voltage signals that are indicative of diastolic and systolic blood pressure (e.g., in mmHg). Combinations of methods, such as BCG, ECG, PPG, blood pressure Pulse Wave and others may be used to determine pulse transit time (PTT), pulse arrival time (PAT), and pre-ejection period (PET).

Abstract: Embodiments relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and portable and wearable media devices. Media devices may include a plurality of RF transceivers and an audio system. The RF transceivers and/or audio system may be used to wirelessly communicate between media devices and allow configuration and other data to be wirelessly transmitted from one media device to another media device. A user device may be used to Bluetooth® (BT) pair with a media device and to install a configuration on the media device. Other media devices may be configured using the configuration without breaking the BT pairing and without the other media device having to BT pair with the user device. Each media device may include at least one antenna and may include an antenna that is de-tunable.

Abstract: Embodiments of the invention relate generally to electrical and electronic hardware, computer software, wired and wireless network communications, and computing devices. More specifically, the embodiments related to structures and techniques for implementing multiple logical representations of audio functions in a wireless audio transmitter, such as a USB dongle configured to transmit and to receive audio data wirelessly via, for example, a Bluetooth link. In one embodiment, a wireless USB audio transceiver can include a multiple mode transmitter configured transmit wireless signals at multiple data rates. Further, the wireless USB audio transceiver can include a first data path modeled as a first audio function, and a second data path modeled as a second audio function. Also, included is a signal detector configured to determine the presence of the audio data on a data path for modifying transmission data rates as a function of the presence of the audio data.

Abstract: Acoustic noise suppression is provided in multiple-microphone systems using Voice Activity Detectors (VAD). A host system receives acoustic signals via multiple microphones. The system also receives information on the vibration of human tissue associated with human voicing activity via the VAD. In response, the system generates a transfer function representative of the received acoustic signals upon determining that voicing information is absent from the received acoustic signals during at least one specified period of time. The system removes noise from the received acoustic signals using the transfer function, thereby producing a denoised acoustic data stream.

Abstract: A hybrid display system for a device includes a high resolution display and a low resolution display that are positioned relative to each other to display an image having mixed resolution. A single high resolution display having a size of 1.5 cm by 10 cm and a first cost may be replaced by a hybrid display having the same overall size but using a smaller size (e.g., 1.5 cm by 4 cm) and lower cost for the high resolution display. To achieve the remaining 6 cm in display size, the low resolution display may have a size of approximately 1.5 cm by 6 cm and a lower cost than either of the high resolution displays, such that a combined cost of the high and low resolution displays in the hybrid display makes the second cost lower than the first cost. The high and low resolution displays may use different display technologies to achieve cost and size tradeoffs.

Abstract: Techniques for respiratory and metabolic monitoring in mobile devices, wearable computing, security, illumination, photography, and other applications may use a phosphor-coated broadband white LED to produce broadband light, which may be transmitted along with ambient light to a target (e.g., ear, face, wrist, or the like). Some scattered light returning from a target may be passed through a spectral filter to produce multiple detector regions sensitive to a different waveband and/or wavelength range, and the detected light may be analyzed to determine a measure of a respiratory rate or effort. In the absence of LED light, ambient light may be sufficient illumination for analysis. The disclosed techniques may provide identifying features of type or status of a tissue target (e.g., respiratory rate, heart rate, heart rate variability, heart function, lung function, fat content, hydration status, confirmation of living tissue, and the like).

Abstract: Mobile device speaker control may include: monitoring one or more devices wirelessly coupled with a data network, receiving one or more data packets from each of the one or more devices, filtering received data packets by evaluating a received signal strength (e.g., RSSI) of the received packets, comparing the received signal strength of each of the received packets to a threshold to determine whether the one or more devices are to perform an action, and performing the action only if one or more indicia other than the received signal strength indicate a near field proximity within the threshold or a direct physical contact between a wireless device receiving the data packets and one of the one or more devices that is wirelessly transmitting the data packets.
