Abstract: In an example, distance determination can utilize an electronic device including an infrared sensor to detect a thermal signature of a subject at a first location and a thermal signature of the subject at a second location, a distance sensor to determine a distance of the subject at the first location from the electronic device, and a controller to determine a physical size based on the determined distance and the thermal signature of the subject at the first location, and determine a distance of the subject at a second location based on the physical size and a thermal signature of the subject at the second location.

Abstract: Examples disclosed herein provide the ability to communicate alarm events on a premises to client devices remotely located with respect to the premises. In one example, a monitoring device extracts a sound originating from the premises, wherein the sound is detected by microphones of a microphone array. The monitoring device performs pattern matching to identify an alarm event associated with the extracted sound, and determines a location of the alarm event within the premises based on information obtained individually by the microphones of the microphone array. The monitoring device communicates the alarm event and the location of the alarm event to a client device remotely located with respect to the premises.

Abstract: Examples disclose a printed circuit board including an antenna and a matching circuit to match an impedance of the antenna. Further, the examples of the printed circuit board provide the printed circuit board is interchangeable among various types of platforms by adjusting the impedance value of the matching circuit without replacing an electrical component of the matching circuit.

Abstract: Example embodiments disclosed herein relate to a connector assembly that includes a plurality of antennas including a first antenna operating at a first frequency and a second antenna operating at a second frequency different from the first antenna. The SMA connector assembly also includes an SMA socket to mount the plurality of antennas on an SMA aperture of the computing device and a controller to select at least one antenna of the plurality of antennas corresponding to at least one operating frequency. Example methods and machine-readable storage media are also disclosed.
