Introduction – Making Sense of the Sensors Everywhere Around Us Embedding sensor technology into products has been a very strong trend in recent years. From smartphones, fitness bands, gaming controllers, smartwatches, head-mounted displays the list of consumer devices with sensors is rapidly expanding. Traditionally we have seen sensors used to track location and movement (e.g. … Continued

A common method for creating a 6 degree of freedom (DoF) device is to track a single marker with a camera to measure linear position, and use an IMU to measure angular position (orientation). This is often used for AR and VR controllers and head tracking. One key challenge is aligning the coordinate frames of … Continued
Introduction – Sensor Hubs and Beyond While sensor fusion based around inertial motion sensors has been around for some time, recent developments in mobile applications have cast a spotlight on the algorithms, processors and infrastructure for sensor fusion on consumer and industrial devices.
Introduction Scope This document describes the narrowband IoT (NB-IoT) radio access technology, and focuses mainly on the primary synchronization process of the NB-IoT in the downlink, which is activated when the user equipment (UE) attempts to receive data from the base station (BS) when it leaves its dormant state and wakes up. When the UE … Continued
Introduction Challenges toward 5G NR Release 15 Compared to previous LTE releases, 5G NR introduces a significant increase in the throughput, latency, and number of users, as well as in the connection density. Because 5G NR is targeted at supporting the entire frequency band, from low band in UHF up to 100 GHz, a number … Continued
The evolution of 4G wireless baseband indicates there are two evolving technologies that are currently competing for the leading position; namely LTE and WiMAX. WiMAX has emerged as the technology of choice for computing devices and M2M, as well as for fixed wireless connections in underdeveloped areas. It is promoted by the WiMAX forum, led by Intel and other companies. LTE … Continued
As demand for Internet content on television increases, service providers and consumer electronics manufacturers need alternative technologies to the traditional up/down/left/right remote control in order to delight consumers with new interactive experiences on TV. This paper describes why pointing is the right solution for controlling the TV experience, and compares two technologies that enable pointing remote controls: touchpad and motion … Continued
