Abstract

A system and method for charging a wireless device is described. A charging apparatus includes a power delivery circuit to provide power to the wireless device and a wireless radio to communicate wirelessly with the wireless device. For example, the information about the wireless device may include at least a device type. The charging apparatus further includes a controller to receive information about the wireless device via the wireless radio and to control an amount of current provided by the power delivery circuit, when powering the wireless device, based at least in part on the received information. For example, the controller may determine that the device type is one of a plurality of recognized device types and subsequently enable the power delivery circuit to provide an amount of current to the wireless device that is optimized for the device type.

First claim

What is claimed is:

1. A sensor apparatus, comprising:
a plurality of sensors to generate sensor data;
one or more data queues to store the sensor data, wherein, upon receiving new sensor data from one of the plurality of sensors, each of the one or more data queues replaces existing sensor data stored for that sensor, the one or more data queues including a first data queue to store a first set of sensor data for each of the plurality of sensors; and
a scheduler to dynamically schedule transmissions of sensor data from the one or more data queues to a wireless device, via a first wireless network, based at least in part on a data throughput rate of the first wireless network and a priority of the sensor data, wherein the data throughput rate of the first wireless network varies over time, and wherein the scheduler schedules the first set of sensor data to be transmitted to the wireless device based on a threshold data throughput rate associated with the first wireless network.

2. The sensor apparatus of claim 1 , wherein the first set of sensor data is stored as a linked list.

3. The sensor apparatus of claim 1 , wherein the threshold data throughput rate is a preconfigured value.

4. The sensor apparatus of claim 1 , wherein the threshold data throughput rate is determined by the scheduler.

5. The sensor apparatus of claim 1 , wherein the one or more data queues further comprises:
a second data queue to store a second set of sensor data for one or more of the plurality of sensors, wherein the second set of sensor data has a lower priority than the first set of sensor data.

6. The sensor apparatus of claim 5 , wherein the scheduler is to schedule sensor data from the second set to be transmitted to the wireless device only when the data throughput rate of the first wireless network exceeds the threshold data throughput rate.

7. The sensor apparatus of claim 1 , wherein the first wireless network is a Bluetooth Low Energy (BLE) network.

8. A method of scheduling wireless data transmissions, the method being performed by one or more processors of a computing system and comprising:
receiving sensor data from a plurality of sensors;
storing the sensor data in one or more data queues, the one or more data queues storing a first set of sensor data for each of the plurality of sensors, wherein the storing includes:
upon receiving new sensor data from one of the plurality of sensors, replacing existing sensor data stored for that sensor; and

dynamically transmitting sensor data from each of the one or more data queues to a wireless device, via a first wireless network, based at least in part on a data throughput rate of the first wireless network and a priority of the sensor data, wherein the data throughput rate of the first wireless network varies over time, and wherein the first set of sensor data is scheduled to be transmitted to the wireless device based on a threshold data throughput rate associated with the first wireless network.

9. The method of claim 8 , wherein the first set of sensor data is stored as a linked list.

10. The method of claim 8 , wherein the threshold data throughput rate is a preconfigured value.

11. The method of claim 8 , wherein the threshold data throughput rate is determined by a scheduler.

12. The method of claim 8 , wherein the storing of the sensor data further comprises:
storing a second set of sensor data for one or more of the plurality of sensors, wherein the second set of sensor data has a lower priority than the first set of sensor data.

13. The method of claim 12 , further comprising:
scheduling sensor data from the second set to be transmitted to the wireless device only when the data throughput rate of the first wireless network exceeds the threshold data throughput rate.

14. The method of claim 8 , wherein the first wireless network is based on the Bluetooth low energy (BLE) specification.
