I came across few interesting patents from Microsoft that got published by the USPTO recently. Below are the some of them with their abstract content. BATTERY WITH COMPUTING, SENSING AND COMMUNICATION CAPABILTIES Electrical battery apparatus embodiments are presented that generally involve incorporating sensing, computing, and communication capabilities into the one common component that a vast number of electronic devices employ–namely batteries. By integrating these capabilities into disposable and/or rechargeable batteries, new functionality and intelligence can be provided to otherwise stand-alone devices. POWER SAVING WI-FI TETHERING The techniques discussed herein reduce the power consumption of a Wi-Fi tethering device by switching the Wi-Fi functionality of the Wi-Fi tethering device from a normal operational mode to a sleep mode during idle intervals. The techniques implement a sleep protocol where a Wi-Fi tethering device and the Wi-Fi client device coordinate and establish a sleep schedule. Moreover, the techniques describe a sleep interval adaptation algorithm to establish sleep duration intervals based on data packet exchange patterns associated with different applications executing on the Wi-Fi...
