A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

BLE chip CC2640R2 12.04.2017

The new CC2640R2F BLE chip is a version of the CC2640 with an increased ROM capacity to house most of the Bluetooh low energy stack 4.2 code along with the TI-RTOS operating system components. Now a typical BLE application for a BLE 4.2-enabled peripheral leaves about 80 kB of FLASH memory free, versus 31 kB for the CC2640F128.

In terms of hardware, the new chip comes in the same packages and is fully pin and connection compatible with the CC2640F128. All external components, including quartz, DC/DC converter binding elements and LC matching elements in the antenna matching circuit remain unchanged. This means that in an already developed device, the CC2640F128 chip can be replaced by the CC2640R2F without making any changes to the product circuit.

To get acquainted with the capabilities of the CC2640R2F and develop BLE applications, Texas Instruments releases the SIMPLELINK_CC2640R2_SDK 1.30.00.25 software package designed for compilation in the CCS7.1 environment. When installing the package, the developer receives a set of directories with TI-RTOS, a BLE stack, peripheral drivers, and ready-made sample applications.

Features of SIMPLELINK_CC2640R2_SDK 1.30.00.25 software:

A complete free Bluetooth 4.2 stack supporting all device types: Peripheral, Central, Broadcaster and Observer.
Support for all features of BLE version 4.2 LE: Secure Connections, Data Length Extension and Privacy 1.2.
The ability to work as a single-chip functionally complete device or as a "Network BLE controller" under the control of an external microcontroller.
Full integration with TI-RTOS for real-time applications with flexible power management.
Multi-role mode with 8 simultaneous connections.
Supports over-the-air firmware update using external or built-in FLASH memory.
Includes BT SIG approved HID over GATT (HOGP), Glucose and Heart Rate and custom TI Audio and firmware update (OAD) profiles.
Supports automatic code generation for Bluetooth GATT profiles using the Bluetooth Developer Studio (BDS) software plugin.
Simple Micro BLE Stack configuration for Beacon mode.
Free code generation option in the Code Composer Studio (CCS) v7.1 development environment.
