Abrégé

Disclosed are techniques to temporarily deactivate or activate the ACL link associated with an isochronous link between a central and a peripheral device of a BLE piconet. The central and peripheral devices may agree to enter into an ACL parked mode after an isochronous link is established between the devices. In the parked mode, the ACL link is in a dormant state without any ACL events. If the central or the peripheral device wants to activate the ACL link to transmit one or more control or data packets, the device may use a CIS subevent on the isochronous link to transmit an LL control PDU. The LL control PDU may contain ACL timing information that specifies the timing of the future ACL event.

A digital phase-locked loop includes a first clock divider, a decimation filter, a proportional integral filter, a signal conditioner, and a digitally controlled oscillator. The first clock divider divides a first clock signal including a first clock rate to generate a second clock signal including a second clock rate less than the first clock rate. The decimation filter converts an input signal at the first clock rate to an output signal at the second clock rate. The proportional integral filter filters the output signal at the second clock rate to generate a filtered output signal. The signal conditioner conditions the filtered output signal at the second clock rate to generate a conditioned output signal. The digitally controlled oscillator generates a carrier clock signal in response to the conditioned output signal.

Abrégé

Disclosed are techniques to use existing BLE broadcast-based signaling protocols to achieve sub-1 ms peripheral-to-central latency even when multiple peripheral devices share the air-time. The techniques adapt existing BLE advertising or broadcast signaling protocols to efficiently allocate air-time to support frequent peripheral-to-central transmissions that are relatively short in duration and less frequent central-to-peripheral transmissions. A broadcast isochronous group (BIG) protocol may be used to reduce peripheral-to-central latency by aggregating broadcast isochronous streams (BIS) from peripheral devices into a BIG. A one-to-many broadcast event that may carry other broadcast data from the central device to the peripheral devices may be used for time synchronization by the peripheral devices and to configure time parameters of broadcast from the peripheral devices. A reverse many-to-one broadcast from the peripheral devices to the central device may be based on the time parameters. The techniques yield low peripheral-to-central latency and natively support encryption in a BLE controller.

Abrégé

A Successive Approximation Analog-to-Digital Converter (SAR_ADC) and method of operating the same are provided. Generally, the SAR_ADC includes a comparator having a first input to receive an input voltage (VIN), and a second input coupled to a n-bit capacitive digital-to-analog converter (DAC) to receive a voltage (VDAC), a Successive Approximation Register (SAR) coupled to a comparator output to provide n digital control signals to the DAC, and to store and output an n-bit binary-number approximating VIN, and a reference buffer to provide a voltage (VREF) to the DAC. The DAC sequentially drives each capacitance beginning with a most significant bit towards VREF, while the comparator compares the resulting VDAC to VIN, and the SAR sets or clears a current bit represented by the capacitance driven. The reference buffer includes adaptive power tuning to dynamically tune a drive-strength of the reference buffer based on the current bit.

Abrégé

Measured signal data, detected by a sensor array of a device, is used to create a generated representation from the measured signal data. The generated representation is compared with a measured representation of the measured signal data to create a correlation coefficient corresponding to a correlation between the generated representation and the measured representation of the measured signal data. A hover event is detected for the device if the correlation coefficient exceeds a first threshold. If the correlation coefficient does not exceed the first threshold, then the measured signal data is determined to not be indicative of a hover event.

Abrégé

Disclosed are methods and systems for a WLAN device to select an operating dynamic frequency selection (DFS) channel that minimizes the probability of radar interference by using aiding information. The aiding information may be a crowd-sourced database of geo-tagged radar zones including one or more DFS channels used within the geo-tagged radar zones that are detected by a plurality of WLAN devices. The WLAN device may query the crowd-sourced database for a geo-tagged radar zone that is nearby to determine if a radar operates on an overlapping DFS channel so it may switch to a different channel. In one aspect, the aiding information may be periodic special action frames broadcast by a WLAN beaconing device over the operating channel of the WLAN device. The special action frames may carry information on one or more channels used by a near-by radar and recommended alternative channels to use by the WLAN device.
