Abstract: A radio frequency (RF) tamper detector of an electronic device can offer improved chassis intrusion monitoring to protect the device from software and hardware-based tampering. The tamper detector can monitor RF noise levels in a first frequency band and in a second frequency band to calculate an RF noise level moving average for each frequency band. If the moving averages in both frequency bands exceed a RF noise threshold, the tamper detector can set a cover removal flag to indicate that a cover of the device housing has been removed. The tamper detector can cause the electronic device to lock or disable a system BIOS when cover removal is detected. Additionally, the electronic device can notify remote monitoring systems (e.g., operated by an IT administrator or warranty support center) to receive additional instructions to secure the device.

Abstract: An example electronic device includes a network communication interface to connect to a conference server, a central control device communication interface to connect to a local central control device, a microphone and a processor. The processor is to receive audio at the microphone and send the audio to the local central control device and to the conference server. The processor is to send the audio to the local central control device such that it is received by a nearby electronic device before the audio is received from the conference server by the nearby electronic device.

Abstract: In an example, a computing device in a particular region is detected based on receipt by the computing device of a wireless beacon signal. A peripheral device connected to the computing device is identified in response to the detection. A location of the peripheral device is determined in response to a determination that the computing device has been moved to outside the particular region. A lost device notification is activated in response to the location being inside the particular region.

Abstract: Techniques for antenna disposition in computing devices are described, in an example, a knuckle hinge coupled to a first component allows rotation of the first component relative to a second component. The knuckle hinge may be separated from the first component by a gap. An antenna may be disposed on the first component.
